The problem was introduced in 81c1099d22b81ebfd20a334ce986c4f753b0db29 where the code from upstream was merged before the audit_event call when it should have been merged right before the _exit call in order to honor the comment that just mentions an override of the exit value. commit 16eaf9d401e70996f89f3f417738a8db421aa959 Author: djm@openbsd.org Date: Wed Aug 28 12:08:26 2024 +0000 upstream: fix test: -F is the argument to specify a non-default ssh_config, not -f (this is sadly not a new bug) OpenBSD-Regress-ID: 45a7bda4cf33f2cea218507d8b6a55cddbcfb322 commit 10ccf611ab8ecba9ce6b0548c5ccd8c1220baf92 Author: deraadt@openbsd.org Date: Fri Aug 23 04:51:00 2024 +0000 upstream: As defined in the RFC, the SSH protocol has negotiable compression support (which is requested as the name "zlib"). Compression starts very early in the session. Relative early in OpenSSH lifetime, privsep was added to sshd, and this required a shared-memory hack so the two processes could see what was going on in the dataflow. This shared-memory hack was soon recognized as a tremendous complexity risk, because it put libz (which very much trusts it's memory) in a dangerous place, and a new option ("zlib@openssh.com") was added begins compression after authentication (aka delayed-compression). That change also permitted removal of the shared-memory hack. Despite removal from the server, the old "zlib" support remained in the client, to allow negotiation with non-OpenSSH daemons which lack the delayed-compression option. This commit deletes support for the older "zlib" option in the client. It reduces our featureset in a small way, and encourages other servers to move to a better design. The SSH protocol is different enough that compressed-key-material attacks like BEAST are unlikely, but who wants to take the chance? We encourage other ssh servers who care about optional compression support to add delayed-zlib support. (Some already do "zlib@openssh.com") ok djm markus OpenBSD-Commit-ID: 6df986f38e4ab389f795a6e39e7c6857a763ba72 commit aee54878255d71bf93aa6e91bbd4eb1825c0d1b9 Author: djm@openbsd.org Date: Thu Aug 22 23:11:30 2024 +0000 upstream: sntrup761x25519-sha512 now has an IANA codepoint assigned, so we can make the algorithm available without the @openssh.com suffix too. ok markus@ deraadt@ OpenBSD-Commit-ID: eeed8fcde688143a737729d3d56d20ab4353770f commit a76a6b85108e3032c8175611ecc5746e7131f876 Author: Darren Tucker Date: Thu Aug 22 20:36:12 2024 +1000 Move rekey test into valgrind-2.

Splitting sshd into sshd/sshd-session broke this, as the process that starts PAM is always sshd-session and the user has no control over this. Hardcode "sshd" as the default PAM service name unless/until we figure out a better way. Should unbreak OSX integration tests. commit bf204bd05c3ae650f87e2b96527688579f59774c Author: Damien Miller Date: Thu Jun 13 15:00:28 2024 +1000 prepare for checking in autogenerated files We plan to check in automatically generated files (config.h.in, etc) on release branches.

This brings back a minimal version of the previous special treatment for Cygwin (and any other platform that sets DISABLE_FD_PASSING): privilege separation remains enabled, but PTY allocation happens in the post-auth user process rather than the monitor. This either requires PTY allocation to not need privilege to begin with (this appears to be the case on Cygwin), or the post-auth privsep process retain privilege (other platforms that set the DISABLE_FD_PASSING option). Keeping privileges here is bad, but the non-Cygwin systems that set DISABLE_FD_PASSING are so deeply legacy that this is likely to be the least of their problems. commit f66d4df5749551380a8c4ae642347675a0b6a2e9 Author: Damien Miller Date: Thu Jun 13 11:33:09 2024 +1000 delay lookup of privsep user until config loaded sshd-session attempting to use options.kerberos_authentication to decide whether it needed to lookup the privsep user before the configuration was loaded. This caused it to get a placeholder value that caused it always to try to lookup the privsep user, breaking at least one test environment. commit f1c42858b94f5d9b58867b34dce3afb39c6b56a8 Author: Damien Miller Date: Thu Jun 13 11:16:57 2024 +1000 missing file for PerSourcePenalties regress test commit 4de80ff4e6fab5a6bb0028e7d57c6c23d1485adb Author: djm@openbsd.org Date: Wed Jun 12 22:36:00 2024 +0000 upstream: split PerSourcePenalties address tracking. Previously it used one shared table and overflow policy for IPv4 and IPv6 addresses, now it will use separate tables and optionally different overflow policies. This prevents misbehaviour from IPv6 addresses (which are vastly easier to obtain many of) from affecting IPv4 connections and may allow for stricter overflow policies. ok deraadt@ OpenBSD-Commit-ID: 12637ed0aa4d5f1f3e702da42ea967cbd8bfdfd9 commit 06ab4c6931b0aaa4334db2faaa7e1069e76d0df6 Author: jmc@openbsd.org Date: Tue Jun 11 05:24:39 2024 +0000 upstream: do not mark up "(default: 20ms)"; OpenBSD-Commit-ID: 54151ecdecfa1b67dcdda4fd24826ef6e2148ad4 commit cfe243cd9fde148ed060637876e27bb55ac78be9 Author: djm@openbsd.org Date: Tue Jun 11 02:54:51 2024 +0000 upstream: reap preauth net child if it hangs up during privsep message send, not just message receive OpenBSD-Commit-ID: 02a093f4ab4f8f83f0cd1ea2bb35b9ca420448f0 commit b0a711c00b9c64afd1c9d6fb538275c6604a2676 Author: djm@openbsd.org Date: Tue Jun 11 01:58:27 2024 +0000 upstream: fix PIDFILE handling, broken for SUDO=doas in last commit here OpenBSD-Regress-ID: 96fec579af228f87a036e94801eb294af9074625 commit 90fb801e2d9241be50a2a7ff79428386442a041f Author: djm@openbsd.org Date: Tue Jun 11 02:00:30 2024 +0000 upstream: reap the pre-auth [net] child if it hangs up during privsep message sending, not just receiving OpenBSD-Commit-ID: f7341605bf08c4c15830910446e6775323f2f8cb commit ef878d58798f6688c7f4d4e417dc0c29023ea831 Author: djm@openbsd.org Date: Tue Jun 11 01:23:25 2024 +0000 upstream: a little more RB_TREE paranoia OpenBSD-Commit-ID: 8dc2fd21eebd8830c4a4d25461ac4fe228e11156 commit fc4e96b2174d6a894d2033421699d091679baced Author: djm@openbsd.org Date: Tue Jun 11 01:22:25 2024 +0000 upstream: fix off-by-one comparison for PerSourcePenalty OpenBSD-Commit-ID: af4f5d01c41ef870b23e55655bfbf73474a6c02b commit 82c836df4ff41145553cd7adb11c5b985aeaa06f Author: djm@openbsd.org Date: Tue Jun 11 01:21:41 2024 +0000 upstream: move tree init before possible early return OpenBSD-Commit-ID: 72e2c5b69f151c08a7c5bf5ad929b97a92c273df commit a2300f015cc4939c4d9c564b58b74e71202dc978 Author: djm@openbsd.org Date: Tue Jun 11 01:07:35 2024 +0000 upstream: update to mention that PerSourcePenalties default to being enabled and document the default values for each parameter.

When PerSourcePenalties are enabled, sshd(8) will monitor the exit status of its child pre-auth session processes. Through the exit status, it can observe situations where the session did not authenticate as expected. These conditions include when the client repeatedly attempted authentication unsucessfully (possibly indicating an attack against one or more accounts, e.g. password guessing), or when client behaviour caused sshd to crash (possibly indicating attempts to exploit sshd). When such a condition is observed, sshd will record a penalty of some duration (e.g. 30 seconds) against the client's address. If this time is above a minimum threshold specified by the PerSourcePenalties, then connections from the client address will be refused (along with any others in the same PerSourceNetBlockSize CIDR range). Repeated offenses by the same client address will accrue greater penalties, up to a configurable maximum. A PerSourcePenaltyExemptList option allows certain address ranges to be exempt from all penalties. We hope these options will make it significantly more difficult for attackers to find accounts with weak/guessable passwords or exploit bugs in sshd(8) itself. PerSourcePenalties is off by default, but we expect to enable it automatically in the near future. much feedback markus@ and others, ok markus@ OpenBSD-Commit-ID: 89ded70eccb2b4926ef0366a4d58a693de366cca commit 916b0b6174e203cf2c5ec9bcf409472eb7ffbf43 Author: Damien Miller Date: Fri Jun 7 03:31:02 2024 +1000 whitespace commit 49b55e44182b8294419aa580cbf043d5b9e3d953 Author: deraadt@openbsd.org Date: Tue Jun 4 15:14:45 2024 +0000 upstream: enable -fret-clean on amd64, for libc libcrypto ld.so kernel, and all the ssh tools.

This step splits sshd into a listener and a session binary. More splits are planned. After this changes, the listener binary will validate the configuration, load the hostkeys, listen on port 22 and manage MaxStartups only. All session handling will be performed by a new sshd-session binary that the listener fork+execs. This reduces the listener process to the minimum necessary and sets us up for future work on the sshd-session binary. feedback/ok markus@ deraadt@ NB. if you're updating via source, please restart sshd after installing, otherwise you run the risk of locking yourself out.

Instead of trying to infer the type of the self hosted tests in each of the driver scripts (inconsistently...), set one of the following variables to "true" in the workflow: VM: tests run in a virtual machine. EPHEMERAL: tests run on an ephemeral virtual machine. PERSISTENT: tests run on a persistent virtual machine REMOTE: tests run on a physical remote host. EPHEMERAL VMs can have multiple instances of any given VM can exist simultaneously and are run by a runner pool. The other types have a dedicated runner instance and can only run a single test at a time. Other settings: SSHFS: We need to sshfs mount over the repo so the workflow can collect build artifacts. This also implies the tests must be run over ssh.

Some programs that invoke ssh(1) using untrusted data do not filter metacharacters in arguments they supply. This could create interactions with user-specified ProxyCommand and other directives that allow shell injection attacks to occur. It's a mistake to invoke ssh(1) with arbitrary untrusted arguments, but getting this stuff right can be tricky, so this should prevent most obvious ways of creating risky situations. It however is not and cannot be perfect: ssh(1) has no practical way of interpreting what shell quoting rules are in use and how they interact with the user's specified ProxyCommand. To allow configurations that use strange user or hostnames to continue to work, this strictness is applied only to names coming from the commandline. Names specified using User or Hostname directives in ssh_config(5) are not affected. feedback/ok millert@ markus@ dtucker@ deraadt@ OpenBSD-Commit-ID: 3b487348b5964f3e77b6b4d3da4c3b439e94b2d9 commit 0cb50eefdd29f0fec31d0e71cc4b004a5f704e67 Author: djm@openbsd.org Date: Mon Dec 18 14:47:20 2023 +0000 upstream: stricter handling of channel window limits This makes ssh/sshd more strict in handling non-compliant peers that send more data than the advertised channel window allows.

We tried working around this (on OpenSSL <1.1 you could define OPENSSL_NO_SHA, NetBSD had USE_LIBC_SHA2, various #define hacks) with varying levels of success. Since OpenSSL >=1.1 removed OPENSSL_NO_SHA and including most OpenSSL headers would bring sha.h in, even if it wasn't used directly this was a constant hassle.

The old behaviour of allowing remote clients from loading providers can be restored using `ssh-agent -O allow-remote-pkcs11`. Detection of local/remote clients requires a ssh(1) that supports the `session-bind@openssh.com` extension. Forwarding access to a ssh-agent socket using non-OpenSSH tools may circumvent this control. ok markus@ OpenBSD-Commit-ID: 4c2bdf79b214ae7e60cc8c39a45501344fa7bd7c commit 892506b13654301f69f9545f48213fc210e5c5cc Author: djm@openbsd.org Date: Wed Jul 19 13:55:53 2023 +0000 upstream: terminate process if requested to load a PKCS#11 provider that isn't a PKCS#11 provider; from / ok markus@ OpenBSD-Commit-ID: 39532cf18b115881bb4cfaee32084497aadfa05c commit f3f56df8ec476b2de6cbdbdfdb77a2a61087829d Author: Damien Miller Date: Wed Jul 19 12:07:18 2023 +1000 agent_fuzz doesn't want stdint.h conditionalised commit 750911fd31d307a767cc86e3bfa90bbbb77b1a25 Author: Damien Miller Date: Tue Jul 18 15:41:12 2023 +1000 conditionalise stdint.h inclusion on HAVE_STDINT_H fixes build on AIX5 at least commit ff047504fa6e008c4092f8929881816b8993bea0 Author: Damien Miller Date: Tue Jul 18 15:30:45 2023 +1000 conditionalise match localnetwork on ifaddrs.h Fixes build breakage on platforms that lack getifaddrs() commit b87b03282e466ca2927954ce93f5dbf0bfdc68f6 Author: djm@openbsd.org Date: Mon Jul 17 06:16:33 2023 +0000 upstream: missing match localnetwork negation check OpenBSD-Commit-ID: 9a08ed8dae27d3f38cf280f1b28d4e0ff41a737a commit 6d6e185ba29ef4274164b77eab4dc763907f8821 Author: jmc@openbsd.org Date: Mon Jul 17 05:41:53 2023 +0000 upstream: - add -P to usage() - sync the arg name to -J in usage() with that in ssh.1 - reformat usage() to match what "man ssh" does on 80width OpenBSD-Commit-ID: 5235dd7aa42e5bf90ae54579d519f92fc107036e commit f1a9898283a0638667b587ee4a950afd61ab51b0 Author: jmc@openbsd.org Date: Mon Jul 17 05:38:10 2023 +0000 upstream: -P before -p in SYNOPSIS; OpenBSD-Commit-ID: 535f5257c779e26c6a662a038d241b017f8cab7c commit eef4d7e873568e1c84c36bb4034e2c3378250a61 Author: jsg@openbsd.org Date: Mon Jul 17 05:36:14 2023 +0000 upstream: configuation -> configuration OpenBSD-Commit-ID: 4776ced33b780f1db0b2902faec99312f26a726b commit dc1dbe94cf6532bd546a3373ad436404f8850e5f Author: djm@openbsd.org Date: Mon Jul 17 05:26:38 2023 +0000 upstream: move other RCSIDs to before their respective license blocks too no code change OpenBSD-Commit-ID: ef5bf46b57726e4260a63b032b0b5ac3b4fe9cd4 commit ebe11044681caff78834ca6b78311ad19c1860b8 Author: djm@openbsd.org Date: Mon Jul 17 05:22:30 2023 +0000 upstream: Move RCSID to before license block and away from #includes, where it caused merge conflict in -portable for each commit :( OpenBSD-Commit-ID: 756ebac963df3245258b962e88150ebab9d5fc20 commit 05c08e5f628de3ecf6f7ea20947735bcfa3201e0 Author: djm@openbsd.org Date: Mon Jul 17 05:20:15 2023 +0000 upstream: return SSH_ERR_KRL_BAD_MAGIC when a KRL doesn't contain a valid magic number and not SSH_ERR_MESSAGE_INCOMPLETE; the former is needed to fall back to text revocation lists in some cases; fixes t-cert-hostkey.

However, the code to sign KRLs and verify KRL signatues was never completed in OpenSSH. Now, some years later, we have SSHSIG support in ssh-keygen that is more general, well tested and actually works. So this removes the semi-finished KRL signing/verification support from OpenSSH and refactors the remaining code to realise the benefit - primarily, we no longer need to perform multiple parsing passes over KRL objects. ok markus@ OpenBSD-Commit-ID: 517437bab3d8180f695c775410c052340e038804 commit 449566f64c21b4578d5c0c431badd0328adc53ed Author: djm@openbsd.org Date: Mon Jul 17 03:57:21 2023 +0000 upstream: Support for KRL extensions.

We tracked the highest contiguous block transferred to deal with this case, but our naive tracking doesn't deal with servers that reorder requests - a misfeature strictly permitted by the protocol but seldom implemented. Adjust the logic to ftruncate() at the highest absolute block received when the transfer is successful. feedback deraadt@ ok markus@ prompted by https://github.com/openssh/openssh-portable/commit/9b733#commitcomment-110679778 OpenBSD-Commit-ID: 4af7fac75958ad8507b4fea58706f3ff0cfddb1b commit c8eb3941758615c8284a48fff47872db926da63c Author: djm@openbsd.org Date: Wed Apr 26 01:36:03 2023 +0000 upstream: Check for ProxyJump=none in CanonicalizeHostname logic.

OpenBSD-Regress-ID: 7e7ddc0beb73e945e1c4c58d51c8a125b518120f commit 131fcbcaffd1e3bcf5ab766ec497b5d768955310 Author: Darren Tucker Date: Wed Mar 1 23:23:02 2023 +1100 Adjust test jobs for new log directory. commit a6f4ac8a2baf77e5361cfa017d0dc250d1409bec Author: dtucker@openbsd.org Date: Wed Mar 1 09:29:32 2023 +0000 upstream: Rework logging for the regression tests. Previously we would log to ssh.log and sshd.log, but that is insufficient for tests that have more than one concurent ssh/sshd. Instead, we'll log to separate datestamped files in a $OBJ/log/ and leave a symlink at the previous location pointing at the most recent instance with an entry in regress.log showing which files were created at each point. This should be sufficient to reconstruct what happened even for tests that use multiple instances of each program. If the test fails, tar up all of the logs for later analysis. This will let us also capture the output from some of the other tools which was previously sent to /dev/null although most of those will be in future commits.

Meaning that the default size of - fd_set is quite sufficient. - -commit 419aa8a312e8d8f491933ca3d5933e602cb05aae -Author: Darren Tucker -Date: Tue Nov 8 12:42:52 2022 +1100 - - Shutdown any VM before trying to check out repo. - - In the case where the previous run did not clean up, the checkout will - fail as it'll leave a stale mount. - -commit a32c07cbb78f65d8527642b96474a83b413f8108 -Author: Darren Tucker -Date: Tue Nov 8 11:33:25 2022 +1100 - - Run vm startup and shutdown from runner temp dir. - - Should work even if the github workspace dir is on a stale sshfs mount. - -commit 2b40a7dfcdb8e616155b9504145aa52b271455aa -Author: Darren Tucker -Date: Tue Nov 8 11:03:31 2022 +1100 - - Add valrind-5 test here too. - -commit 2ea03d1f6d0a05ee2b63ed2dc0f2d54f1e4655a1 -Author: Darren Tucker -Date: Tue Nov 8 09:21:10 2022 +1100 - - Update checkout and upload actions. - - Update actions/checkout and actions/upload-artifact to main branch for - compatibility with node.js v16. - -commit 4e316ff0f18a118232bb9ac6512ee62773a9e8ea -Author: Darren Tucker -Date: Tue Nov 8 09:17:04 2022 +1100 - - Split out rekey test since it runs the longest. - -commit 21625a6424258a92a96a3bb73ae6aabc5ed8a6b4 -Author: dtucker@openbsd.org -Date: Mon Nov 7 10:09:28 2022 +0000 - - upstream: The IdentityFile option in ssh_config can also be used to - - specify a public key file, as documented in ssh.1 for the -i option.

Please read https://www.openssh.com/report.html for bug reporting instructions and note that we do not use Github for bug reporting or patch/pull-request management. This is the port of OpenBSD's excellent OpenSSH[0] to Linux and other Unices. OpenSSH is based on the last free version of Tatu Ylonen's sample implementation with all patent-encumbered algorithms removed (to external libraries), all known security bugs fixed, new features reintroduced and many other clean-ups. OpenSSH has been created by Aaron Campbell, Bob Beck, Markus Friedl, Niels Provos, Theo de Raadt, and Dug Song. It has a homepage at https://www.openssh.com/ This port consists of the re-introduction of autoconf support, PAM support, EGD/PRNGD support and replacements for OpenBSD library functions that are (regrettably) absent from other unices. This port has been best tested on AIX, Cygwin, HP-UX, Linux, MacOS/X, FreeBSD, NetBSD, OpenBSD, OpenServer, Solaris and UnixWare. This version actively tracks changes in the OpenBSD CVS repository. The PAM support is now more functional than the popular packages of commercial ssh-1.2.x. It checks "account" and "session" modules for all logins, not just when using password authentication. There is now several mailing lists for this port of OpenSSH. Please refer to https://www.openssh.com/list.html for details on how to join. Please send bug reports and patches to https://bugzilla.mindrot.org or the mailing list openssh-unix-dev@mindrot.org. To mitigate spam, the list only allows posting from subscribed addresses. Code contribution are welcomed, but please follow the OpenBSD style guidelines[1]. Please refer to the INSTALL document for information on dependencies and how to install OpenSSH on your system. Damien Miller Miscellania - This version of OpenSSH is based upon code retrieved from the OpenBSD CVS repository which in turn was based on the last free sample implementation released by Tatu Ylonen.

X11 connections and arbitrary TCP/IP ports can also be forwarded over the secure channel. OpenSSH is OpenBSD's version of the last free version of SSH, bringing it up to date in terms of security and features, as well as removing all patented algorithms to separate libraries. This package includes the core files necessary for both the OpenSSH client and server. To make this package useful, you should also install openssh-clients, openssh-server, or both. %description clients OpenSSH is a free version of SSH (Secure SHell), a program for logging into and executing commands on a remote machine. This package includes the clients necessary to make encrypted connections to SSH servers. You'll also need to install the openssh package on OpenSSH clients. %description server OpenSSH is a free version of SSH (Secure SHell), a program for logging into and executing commands on a remote machine. This package contains the secure shell daemon (sshd). The sshd daemon allows SSH clients to securely connect to your SSH server. You also need to have the openssh package installed. %description askpass OpenSSH is a free version of SSH (Secure SHell), a program for logging into and executing commands on a remote machine. This package contains an X11 passphrase dialog for OpenSSH. %description askpass-gnome OpenSSH is a free version of SSH (Secure SHell), a program for logging into and executing commands on a remote machine. This package contains an X11 passphrase dialog for OpenSSH and the GNOME GUI desktop environment. %prep %if ! %{no_x11_askpass} %setup -q -a 1 %else %setup -q %endif %build %if %{rescue} CFLAGS="$RPM_OPT_FLAGS -Os"; export CFLAGS %endif %configure \ --sysconfdir=%{_sysconfdir}/ssh \ --libexecdir=%{_libexecdir}/openssh \ --datadir=%{_datadir}/openssh \ --with-default-path=/usr/local/bin:/bin:/usr/bin \ --with-superuser-path=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin \ --with-privsep-path=%{_var}/empty/sshd \ --mandir=%{_mandir} \ --with-mantype=man \ --disable-strip \ %if %{without_openssl} --without-openssl \ %endif %if %{scard} --with-smartcard \ %endif %if %{rescue} --without-pam \ %else --with-pam \ %endif %if %{kerberos5} --with-kerberos5=$K5DIR \ %endif %if %{static_libcrypto} perl -pi -e "s|-lcrypto|%{_libdir}/libcrypto.a|g" Makefile %endif make %if ! %{no_x11_askpass} pushd x11-ssh-askpass-%{aversion} %configure --libexecdir=%{_libexecdir}/openssh xmkmf -a make popd %endif # Define a variable to toggle gnome1/gtk2 building.

Overhaul to deal with newer versions of SuSE and OpenSSH * Mon Jun 12 2000 Damien Miller - Glob manpages to catch compressed files * Wed Mar 15 2000 Damien Miller - Updated for new location - Updated for new gnome-ssh-askpass build * Sun Dec 26 1999 Chris Saia - Made symlink to gnome-ssh-askpass called ssh-askpass * Wed Nov 24 1999 Chris Saia - Removed patches that included /etc/pam.d/sshd, /sbin/init.d/rc.sshd, and /var/adm/fillup-templates/rc.config.sshd, since Damien merged these into his released tarfile - Changed permissions on ssh_config in the install procedure to 644 from 600 even though it was correct in the %files section and thus right in the RPMs - Postinstall script for the server now only prints "Generating SSH host key..." if we need to actually do this, in order to eliminate a confusing message if an SSH host key is already in place - Marked all manual pages as %doc(umentation) * Mon Nov 22 1999 Chris Saia - Added flag to configure daemon with TCP Wrappers support - Added building prerequisites (works in RPM 3.0 and newer) * Thu Nov 18 1999 Chris Saia - Made this package correct for SuSE. - Changed instances of pam_pwdb.so to pam_unix.so, since it works more properly with SuSE, and lib_pwdb.so isn't installed by default. * Mon Nov 15 1999 Damien Miller - Split subpackages further based on patch from jim knoble * Sat Nov 13 1999 Damien Miller - Added 'Obsoletes' directives * Tue Nov 09 1999 Damien Miller - Use make install - Subpackages * Mon Nov 08 1999 Damien Miller -

For utmp systems * this usually means login() and logout() or setutent() etc., probably * in libutil, along with logwtmp() etc. On these systems, we fall back * to writing the files directly if we have to, though this method * requires very thorough testing so we do not corrupt local auditing * information. These files and their access methods are very system * specific indeed. * * For utmpx systems, the corresponding library functions are * setutxent() etc. To the author's knowledge, all utmpx systems have * these library functions and so no direct write is attempted. If such * a system exists and needs support, direct analogues of the [uw]tmp * code should suffice. * * Retrieving the time of last login ('lastlog') is in some ways even * more problemmatic than login recording. Some systems provide a * simple table of all users which we seek based on uid and retrieve a * relatively standard structure. Others record the same information in * a directory with a separate file, and others don't record the * information separately at all. For systems in the latter category, * we look backwards in the wtmp or wtmpx file for the last login entry * for our user. Naturally this is slower and on busy systems could * incur a significant performance penalty. * * Calling the new code * -------------------- * * In OpenSSH all login recording and retrieval is performed in * login.c. Here you'll find working examples. Also, in the logintest.c * program there are more examples. * * Internal handler calling method * ------------------------------- * * When a call is made to login_login() or login_logout(), both * routines set a struct logininfo flag defining which action (log in, * or log out) is to be taken. They both then call login_write(), which * calls whichever of the many structure-specific handlers autoconf * selects for the local system. * * The handlers themselves handle system data structure specifics. Both * struct utmp and struct utmpx have utility functions (see * construct_utmp*()) to try to make it simpler to add extra systems * that introduce new features to either structure. * * While it may seem terribly wasteful to replicate so much similar * code for each method, experience has shown that maintaining code to * write both struct utmp and utmpx in one function, whilst maintaining * support for all systems whether they have library support or not, is * a difficult and time-consuming task. * * Lastlog support proceeds similarly. Functions login_get_lastlog() * (and its OpenSSH-tuned friend login_get_lastlog_time()) call * getlast_entry(), which tries one of three methods to find the last * login time. It uses local system lastlog support if it can, * otherwise it tries wtmp or wtmpx before giving up and returning 0, * meaning "tilt". * * Maintenance * ----------- * * In many cases it's possible to tweak autoconf to select the correct * methods for a particular platform, either by improving the detection * code (best), or by presetting DISABLE_ or CONF__FILE * symbols for the platform. * * Use logintest to check which symbols are defined before modifying * configure.ac and loginrec.c. (You have to build logintest yourself * with 'make logintest' as it's not built by default.) * * Otherwise, patches to the specific method(s) are very helpful! */ #include "includes.h" #include #include #include #ifdef HAVE_SYS_TIME_H # include #endif #include #include #include #include #ifdef HAVE_PATHS_H # include #endif #include #include #include #include #include #include #include "xmalloc.h" #include "sshkey.h" #include "hostfile.h" #include "ssh.h" #include "loginrec.h" #include "log.h" #include "atomicio.h" #include "packet.h" #include "canohost.h" #include "auth.h" #include "sshbuf.h" #include "ssherr.h" #include "misc.h" #ifdef HAVE_UTIL_H # include #endif /** ** prototypes for helper functions in this file **/ #if HAVE_UTMP_H void set_utmp_time(struct logininfo *li, struct utmp *ut); void construct_utmp(struct logininfo *li, struct utmp *ut); #endif #ifdef HAVE_UTMPX_H void set_utmpx_time(struct logininfo *li, struct utmpx *ut); void construct_utmpx(struct logininfo *li, struct utmpx *ut); #endif int utmp_write_entry(struct logininfo *li); int utmpx_write_entry(struct logininfo *li); int wtmp_write_entry(struct logininfo *li); int wtmpx_write_entry(struct logininfo *li); int lastlog_write_entry(struct logininfo *li); int syslogin_write_entry(struct logininfo *li); int getlast_entry(struct logininfo *li); int lastlog_get_entry(struct logininfo *li); int utmpx_get_entry(struct logininfo *li); int wtmp_get_entry(struct logininfo *li); int wtmpx_get_entry(struct logininfo *li); extern struct sshbuf *loginmsg; /* pick the shortest string */ #define MIN_SIZEOF(s1,s2) (sizeof(s1) < sizeof(s2) ? sizeof(s1) : sizeof(s2)) /** ** platform-independent login functions **/ /* * login_login(struct logininfo *) - Record a login * * Call with a pointer to a struct logininfo initialised with * login_init_entry() or login_alloc_entry() * * Returns: * >0 if successful * 0 on failure (will use OpenSSH's logging facilities for diagnostics) */ int login_login(struct logininfo *li) { li->type = LTYPE_LOGIN; return (login_write(li)); } /* * login_logout(struct logininfo *) - Record a logout * * Call as with login_login() * * Returns: * >0 if successful * 0 on failure (will use OpenSSH's logging facilities for diagnostics) */ int login_logout(struct logininfo *li) { li->type = LTYPE_LOGOUT; return (login_write(li)); } /* * login_get_lastlog_time(int) - Retrieve the last login time * * Retrieve the last login time for the given uid.

New moduli may be generated with ssh-keygen(1) using a two-step process. An initial candidate generation pass, using ssh-keygen -M generate, calculates numbers that are likely to be useful. A second primality testing pass, using ssh-keygen -M screen, provides a high degree of assurance that the numbers are prime and are safe for use in Diffie- Hellman operations by sshd(8). This moduli format is used as the output from each pass. The file consists of newline-separated records, one per modulus, containing seven space-separated fields. These fields are as follows: timestamp The time that the modulus was last processed as YYYYMMDDHHMMSS. type Decimal number specifying the internal structure of the prime modulus. Supported types are: 0 Unknown, not tested. 2 "Safe" prime; (p-1)/2 is also prime. 4 Sophie Germain; 2p+1 is also prime. Moduli candidates initially produced by ssh-keygen(1) are Sophie Germain primes (type 4). Further primality testing with ssh-keygen(1) produces safe prime moduli (type 2) that are ready for use in sshd(8). Other types are not used by OpenSSH. tests Decimal number indicating the type of primality tests that the number has been subjected to represented as a bitmask of the following values: 0x00 Not tested. 0x01 Composite number M-bM-^@M-^S not prime. 0x02 Sieve of Eratosthenes. 0x04 Probabilistic Miller-Rabin primality tests. The ssh-keygen(1) moduli candidate generation uses the Sieve of Eratosthenes (flag 0x02). Subsequent ssh-keygen(1) primality tests are Miller-Rabin tests (flag 0x04). trials Decimal number indicating the number of primality trials that have been performed on the modulus. size Decimal number indicating the size of the prime in bits. generator The recommended generator for use with this modulus (hexadecimal). modulus The modulus itself in hexadecimal. When performing Diffie-Hellman Group Exchange, sshd(8) first estimates the size of the modulus required to produce enough Diffie-Hellman output to sufficiently key the selected symmetric cipher. sshd(8) then randomly selects a modulus from /etc/moduli that best meets the size requirement.

The source and target may be specified as a local pathname, a remote host with optional path in the form [user@]host:[path], or a URI in the form scp://[user@]host[:port][/path]. Local file names can be made explicit using absolute or relative pathnames to avoid scp treating file names containing M-bM-^@M-^X:M-bM-^@M-^Y as host specifiers. When copying between two remote hosts, if the URI format is used, a port cannot be specified on the target if the -R option is used. The options are as follows: -3 Copies between two remote hosts are transferred through the local host. Without this option the data is copied directly between the two remote hosts. Note that, when using the legacy SCP protocol (via the -O flag), this option selects batch mode for the second host as scp cannot ask for passwords or passphrases for both hosts. This mode is the default. -4 Forces scp to use IPv4 addresses only. -6 Forces scp to use IPv6 addresses only. -A Allows forwarding of ssh-agent(1) to the remote system. The default is not to forward an authentication agent. -B Selects batch mode (prevents asking for passwords or passphrases). -C Compression enable. Passes the -C flag to ssh(1) to enable compression. -c cipher Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1). -D sftp_server_path Connect directly to a local SFTP server program rather than a remote one via ssh(1). This option may be useful in debugging the client and server. -F ssh_config Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1). -i identity_file Selects the file from which the identity (private key) for public key authentication is read. This option is directly passed to ssh(1). -J destination Connect to the target host by first making an scp connection to the jump host described by destination and then establishing a TCP forwarding to the ultimate destination from there. Multiple jump hops may be specified separated by comma characters. This is a shortcut to specify a ProxyJump configuration directive. This option is directly passed to ssh(1). -l limit Limits the used bandwidth, specified in Kbit/s. -O Use the legacy SCP protocol for file transfers instead of the SFTP protocol. Forcing the use of the SCP protocol may be necessary for servers that do not implement SFTP, for backwards- compatibility for particular filename wildcard patterns and for expanding paths with a M-bM-^@M-^X~M-bM-^@M-^Y prefix for older SFTP servers. -o ssh_option Can be used to pass options to ssh in the format used in ssh_config(5). This is useful for specifying options for which there is no separate scp command-line flag. For full details of the options listed below, and their possible values, see ssh_config(5).

Note that this option is written with a capital M-bM-^@M-^XPM-bM-^@M-^Y, because -p is already reserved for preserving the times and mode bits of the file. -p Preserves modification times, access times, and file mode bits from the source file. -q Quiet mode: disables the progress meter as well as warning and diagnostic messages from ssh(1). -R Copies between two remote hosts are performed by connecting to the origin host and executing scp there. This requires that scp running on the origin host can authenticate to the destination host without requiring a password. -r Recursively copy entire directories. Note that scp follows symbolic links encountered in the tree traversal. -S program Name of program to use for the encrypted connection. The program must understand ssh(1) options. -T Disable strict filename checking. By default when copying files from a remote host to a local directory scp checks that the received filenames match those requested on the command-line to prevent the remote end from sending unexpected or unwanted files. Because of differences in how various operating systems and shells interpret filename wildcards, these checks may cause wanted files to be rejected. This option disables these checks at the expense of fully trusting that the server will not send unexpected filenames. -v Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection, authentication, and configuration problems. -X sftp_option Specify an option that controls aspects of SFTP protocol behaviour. The valid options are: nrequests=value Controls how many concurrent SFTP read or write requests may be in progress at any point in time during a download or upload. By default 64 requests may be active concurrently. buffer=value Controls the maximum buffer size for a single SFTP read/write operation used during download or upload. By default a 32KB buffer is used. EXIT STATUS The scp utility exitsM-BM- 0 on success, andM-BM- >0 if an error occurs.

Since OpenSSH 9.0, scp has used the SFTP protocol for transfers by default. AUTHORS Timo Rinne Tatu Ylonen CAVEATS The legacy SCP protocol (selected by the -O flag) requires execution of the remote user's shell to perform glob(3) pattern matching. This requires careful quoting of any characters that have special meaning to the remote shell, such as quote characters. -OpenBSD 7.5 December 16, 2022 OpenBSD 7.5 +OpenBSD 7.6 December 16, 2022 OpenBSD 7.6 diff --git a/servconf.c b/servconf.c index 89b8413e87d7..bef1b511ed5d 100644 --- a/servconf.c +++ b/servconf.c @@ -1,3375 +1,3404 @@ -/* $OpenBSD: servconf.c,v 1.418 2024/09/15 03:09:44 djm Exp $ */ +/* $OpenBSD: servconf.c,v 1.419 2024/09/25 01:24:04 djm Exp $ */ /* * Copyright (c) 1995 Tatu Ylonen , Espoo, Finland * All rights reserved * * As far as I am concerned, the code I have written for this software * can be used freely for any purpose.

Command-line flags to sftp-server should be specified in the Subsystem declaration. See sshd_config(5) for more information. Valid options are: -d start_directory Specifies an alternate starting directory for users. The pathname may contain the following tokens that are expanded at runtime: %% is replaced by a literal '%', %d is replaced by the home directory of the user being authenticated, and %u is replaced by the username of that user. The default is to use the user's home directory. This option is useful in conjunction with the sshd_config(5) ChrootDirectory option. -e Causes sftp-server to print logging information to stderr instead of syslog for debugging. -f log_facility Specifies the facility code that is used when logging messages from sftp-server. The possible values are: DAEMON, USER, AUTH, LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7. The default is AUTH. -h Displays sftp-server usage information. -l log_level Specifies which messages will be logged by sftp-server. The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2, and DEBUG3. INFO and VERBOSE log transactions that sftp-server performs on behalf of the client. DEBUG and DEBUG1 are equivalent. DEBUG2 and DEBUG3 each specify higher levels of debugging output. The default is ERROR. -P denied_requests Specifies a comma-separated list of SFTP protocol requests that are banned by the server. sftp-server will reply to any denied request with a failure. The -Q flag can be used to determine the supported request types. If both denied and allowed lists are specified, then the denied list is applied before the allowed list. -p allowed_requests Specifies a comma-separated list of SFTP protocol requests that are permitted by the server. All request types that are not on the allowed list will be logged and replied to with a failure message. Care must be taken when using this feature to ensure that requests made implicitly by SFTP clients are permitted. -Q protocol_feature Queries protocol features supported by sftp-server. At present the only feature that may be queried is M-bM-^@M-^\requestsM-bM-^@M-^], which may be used to deny or allow specific requests (flags -P and -p respectively). -R Places this instance of sftp-server into a read-only mode. Attempts to open files for writing, as well as other operations that change the state of the filesystem, will be denied. -u umask Sets an explicit umask(2) to be applied to newly-created files and directories, instead of the user's default mask. On some systems, sftp-server must be able to access /dev/log for logging to work, and use of sftp-server in a chroot configuration therefore requires that syslogd(8) establish a logging socket inside the chroot directory.

It may also use many features of ssh, such as public key authentication and compression. The destination may be specified either as [user@]host[:path] or as a URI in the form sftp://[user@]host[:port][/path]. If the destination includes a path and it is not a directory, sftp will retrieve files automatically if a non-interactive authentication method is used; otherwise it will do so after successful interactive authentication. If no path is specified, or if the path is a directory, sftp will log in to the specified host and enter interactive command mode, changing to the remote directory if one was specified. An optional trailing slash can be used to force the path to be interpreted as a directory. Since the destination formats use colon characters to delimit host names from path names or port numbers, IPv6 addresses must be enclosed in square brackets to avoid ambiguity. The options are as follows: -4 Forces sftp to use IPv4 addresses only. -6 Forces sftp to use IPv6 addresses only. -A Allows forwarding of ssh-agent(1) to the remote system. The default is not to forward an authentication agent. -a Attempt to continue interrupted transfers rather than overwriting existing partial or complete copies of files. If the partial contents differ from those being transferred, then the resultant file is likely to be corrupt. -B buffer_size Specify the size of the buffer that sftp uses when transferring files. Larger buffers require fewer round trips at the cost of higher memory consumption. The default is 32768 bytes. -b batchfile Batch mode reads a series of commands from an input batchfile instead of stdin. Since it lacks user interaction, it should be used in conjunction with non-interactive authentication to obviate the need to enter a password at connection time (see sshd(8) and ssh-keygen(1) for details). A batchfile of M-bM-^@M-^X-M-bM-^@M-^Y may be used to indicate standard input. sftp will abort if any of the following commands fail: get, put, reget, reput, rename, ln, rm, mkdir, chdir, ls, lchdir, copy, cp, chmod, chown, chgrp, lpwd, df, symlink, and lmkdir. Termination on error can be suppressed on a command by command basis by prefixing the command with a M-bM-^@M-^X-M-bM-^@M-^Y character (for example, -rm /tmp/blah*). Echo of the command may be suppressed by prefixing the command with a M-bM-^@M-^X@M-bM-^@M-^Y character. These two prefixes may be combined in any order, for example -@ls /bsd. -C Enables compression (via ssh's -C flag). -c cipher Selects the cipher to use for encrypting the data transfers. This option is directly passed to ssh(1). -D sftp_server_command Connect directly to a local sftp server (rather than via ssh(1)). A command and arguments may be specified, for example "/path/sftp-server -el debug3". This option may be useful in debugging the client and server. -F ssh_config Specifies an alternative per-user configuration file for ssh(1). This option is directly passed to ssh(1). -f Requests that files be flushed to disk immediately after transfer. When uploading files, this feature is only enabled if the server implements the "fsync@openssh.com" extension. -i identity_file Selects the file from which the identity (private key) for public key authentication is read. This option is directly passed to ssh(1). -J destination Connect to the target host by first making an sftp connection to the jump host described by destination and then establishing a TCP forwarding to the ultimate destination from there. Multiple jump hops may be specified separated by comma characters. This is a shortcut to specify a ProxyJump configuration directive. This option is directly passed to ssh(1). -l limit Limits the used bandwidth, specified in Kbit/s. -N Disables quiet mode, e.g. to override the implicit quiet mode set by the -b flag. -o ssh_option Can be used to pass options to ssh in the format used in ssh_config(5). This is useful for specifying options for which there is no separate sftp command-line flag. For example, to specify an alternate port use: sftp -oPort=24. For full details of the options listed below, and their possible values, see ssh_config(5).

Increasing this may slightly improve file transfer speed but will increase memory usage. The default is 64 outstanding requests. -r Recursively copy entire directories when uploading and downloading. Note that sftp does not follow symbolic links encountered in the tree traversal. -S program Name of the program to use for the encrypted connection. The program must understand ssh(1) options. -s subsystem | sftp_server Specifies the SSH2 subsystem or the path for an sftp server on the remote host. A path is useful when the remote sshd(8) does not have an sftp subsystem configured. -v Raise logging level. This option is also passed to ssh. -X sftp_option Specify an option that controls aspects of SFTP protocol behaviour. The valid options are: nrequests=value Controls how many concurrent SFTP read or write requests may be in progress at any point in time during a download or upload. By default 64 requests may be active concurrently. buffer=value Controls the maximum buffer size for a single SFTP read/write operation used during download or upload. By default a 32KB buffer is used. INTERACTIVE COMMANDS Once in interactive mode, sftp understands a set of commands similar to those of ftp(1). Commands are case insensitive. Pathnames that contain spaces must be enclosed in quotes. Any special characters contained within pathnames that are recognized by glob(3) must be escaped with backslashes (M-bM-^@M-^X\M-bM-^@M-^Y). bye Quit sftp. cd [path] Change remote directory to path. If path is not specified, then change directory to the one the session started in. chgrp [-h] grp path Change group of file path to grp. path may contain glob(7) characters and may match multiple files. grp must be a numeric GID. If the -h flag is specified, then symlinks will not be followed. Note that this is only supported by servers that implement the "lsetstat@openssh.com" extension. chmod [-h] mode path Change permissions of file path to mode. path may contain glob(7) characters and may match multiple files. If the -h flag is specified, then symlinks will not be followed. Note that this is only supported by servers that implement the "lsetstat@openssh.com" extension. chown [-h] own path Change owner of file path to own. path may contain glob(7) characters and may match multiple files. own must be a numeric UID. If the -h flag is specified, then symlinks will not be followed. Note that this is only supported by servers that implement the "lsetstat@openssh.com" extension. copy oldpath newpath Copy remote file from oldpath to newpath. Note that this is only supported by servers that implement the "copy-data" extension. cp oldpath newpath Alias to copy command. df [-hi] [path] Display usage information for the filesystem holding the current directory (or path if specified). If the -h flag is specified, the capacity information will be displayed using "human-readable" suffixes. The -i flag requests display of inode information in addition to capacity information. This command is only supported on servers that implement the M-bM-^@M-^\statvfs@openssh.comM-bM-^@M-^] extension. exit Quit sftp. get [-afpR] remote-path [local-path] Retrieve the remote-path and store it on the local machine. If the local path name is not specified, it is given the same name it has on the remote machine. remote-path may contain glob(7) characters and may match multiple files. If it does and local-path is specified, then local-path must specify a directory. If the -a flag is specified, then attempt to resume partial transfers of existing files. Note that resumption assumes that any partial copy of the local file matches the remote copy. If the remote file contents differ from the partial local copy then the resultant file is likely to be corrupt. If the -f flag is specified, then fsync(2) will be called after the file transfer has completed to flush the file to disk. If the -p flag is specified, then full file permissions and access times are copied too. If the -R flag is specified then directories will be copied recursively. Note that sftp does not follow symbolic links when performing recursive transfers. help Display help text. lcd [path] Change local directory to path. If path is not specified, then change directory to the local user's home directory. lls [ls-options [path]] Display local directory listing of either path or current directory if path is not specified. ls-options may contain any flags supported by the local system's ls(1) command. path may contain glob(7) characters and may match multiple files. lmkdir path Create local directory specified by path. ln [-s] oldpath newpath Create a link from oldpath to newpath. If the -s flag is specified the created link is a symbolic link, otherwise it is a hard link. lpwd Print local working directory. ls [-1afhlnrSt] [path] Display a remote directory listing of either path or the current directory if path is not specified. path may contain glob(7) characters and may match multiple files. The following flags are recognized and alter the behaviour of ls accordingly: -1 Produce single columnar output. -a List files beginning with a dot (M-bM-^@M-^X.M-bM-^@M-^Y). -f Do not sort the listing. The default sort order is lexicographical. -h When used with a long format option, use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte, Petabyte, and Exabyte in order to reduce the number of digits to four or fewer using powers of 2 for sizes (K=1024, M=1048576, etc.). -l Display additional details including permissions and ownership information. -n Produce a long listing with user and group information presented numerically. -r Reverse the sort order of the listing. -S Sort the listing by file size. -t Sort the listing by last modification time. lumask umask Set local umask to umask. mkdir path Create remote directory specified by path. progress Toggle display of progress meter. put [-afpR] local-path [remote-path] Upload local-path and store it on the remote machine. If the remote path name is not specified, it is given the same name it has on the local machine. local-path may contain glob(7) characters and may match multiple files. If it does and remote-path is specified, then remote-path must specify a directory. If the -a flag is specified, then attempt to resume partial transfers of existing files. Note that resumption assumes that any partial copy of the remote file matches the local copy. If the local file contents differ from the remote local copy then the resultant file is likely to be corrupt. If the -f flag is specified, then a request will be sent to the server to call fsync(2) after the file has been transferred. Note that this is only supported by servers that implement the "fsync@openssh.com" extension. If the -p flag is specified, then full file permissions and access times are copied too. If the -R flag is specified then directories will be copied recursively. Note that sftp does not follow symbolic links when performing recursive transfers. pwd Display remote working directory. quit Quit sftp. reget [-fpR] remote-path [local-path] Resume download of remote-path. Equivalent to get with the -a flag set. reput [-fpR] local-path [remote-path] Resume upload of local-path.

After loading a private key, ssh-add will try to load corresponding certificate information from the filename obtained by appending -cert.pub to the name of the private key file. Alternative file names can be given on the command line. If any file requires a passphrase, ssh-add asks for the passphrase from the user. The passphrase is read from the user's tty. ssh-add retries the last passphrase if multiple identity files are given. The authentication agent must be running and the SSH_AUTH_SOCK environment variable must contain the name of its socket for ssh-add to work. The options are as follows: -C When loading keys into or deleting keys from the agent, process certificates only and skip plain keys. -c Indicates that added identities should be subject to confirmation before being used for authentication. Confirmation is performed by ssh-askpass(1). Successful confirmation is signaled by a zero exit status from ssh-askpass(1), rather than text entered into the requester. -D Deletes all identities from the agent. -d Instead of adding identities, removes identities from the agent. If ssh-add has been run without arguments, the keys for the default identities and their corresponding certificates will be removed. Otherwise, the argument list will be interpreted as a list of paths to public key files to specify keys and certificates to be removed from the agent. If no public key is found at a given path, ssh-add will append .pub and retry. If the argument list consists of M-bM-^@M-^\-M-bM-^@M-^] then ssh-add will read public keys to be removed from standard input. -E fingerprint_hash Specifies the hash algorithm used when displaying key fingerprints. Valid options are: M-bM-^@M-^\md5M-bM-^@M-^] and M-bM-^@M-^\sha256M-bM-^@M-^]. The default is M-bM-^@M-^\sha256M-bM-^@M-^]. -e pkcs11 Remove keys provided by the PKCS#11 shared library pkcs11. -H hostkey_file Specifies a known hosts file to look up hostkeys when using destination-constrained keys via the -h flag. This option may be specified multiple times to allow multiple files to be searched. If no files are specified, ssh-add will use the default ssh_config(5) known hosts files: ~/.ssh/known_hosts, ~/.ssh/known_hosts2, /etc/ssh/ssh_known_hosts, and /etc/ssh/ssh_known_hosts2. -h destination_constraint When adding keys, constrain them to be usable only through specific hosts or to specific destinations. Destination constraints of the form M-bM-^@M-^X[user@]dest-hostnameM-bM-^@M-^Y permit use of the key only from the origin host (the one running ssh-agent(1)) to the listed destination host, with optional user name. Constraints of the form M-bM-^@M-^Xsrc-hostname>[user@]dst-hostnameM-bM-^@M-^Y allow a key available on a forwarded ssh-agent(1) to be used through a particular host (as specified by M-bM-^@M-^Xsrc-hostnameM-bM-^@M-^Y) to authenticate to a further host, specified by M-bM-^@M-^Xdst-hostnameM-bM-^@M-^Y. Multiple destination constraints may be added when loading keys. When attempting authentication with a key that has destination constraints, the whole connection path, including ssh-agent(1) forwarding, is tested against those constraints and each hop must be permitted for the attempt to succeed. For example, if key is forwarded to a remote host, M-bM-^@M-^Xhost-bM-bM-^@M-^Y, and is attempting authentication to another host, M-bM-^@M-^Xhost-cM-bM-^@M-^Y, then the operation will be successful only if M-bM-^@M-^Xhost-bM-bM-^@M-^Y was permitted from the origin host and the subsequent M-bM-^@M-^Xhost-b>host-cM-bM-^@M-^Y hop is also permitted by destination constraints. Hosts are identified by their host keys, and are looked up from known hosts files by ssh-add. Wildcards patterns may be used for hostnames and certificate host keys are supported. By default, keys added by ssh-add are not destination constrained. Destination constraints were added in OpenSSH release 8.9. Support in both the remote SSH client and server is required when using destination-constrained keys over a forwarded ssh-agent(1) channel. It is also important to note that destination constraints can only be enforced by ssh-agent(1) when a key is used, or when it is forwarded by a cooperating ssh(1). Specifically, it does not prevent an attacker with access to a remote SSH_AUTH_SOCK from forwarding it again and using it on a different host (but only to a permitted destination). -K Load resident keys from a FIDO authenticator. -k When loading keys into or deleting keys from the agent, process plain private keys only and skip certificates. -L Lists public key parameters of all identities currently represented by the agent. -l Lists fingerprints of all identities currently represented by the agent. -q Be quiet after a successful operation. -S provider Specifies a path to a library that will be used when adding FIDO authenticator-hosted keys, overriding the default of using the internal USB HID support. -s pkcs11 Add keys provided by the PKCS#11 shared library pkcs11. Certificate files may optionally be listed as command-line arguments. If these are present, then they will be loaded into the agent using any corresponding private keys loaded from the PKCS#11 token. -T pubkey ... Tests whether the private keys that correspond to the specified pubkey files are usable by performing sign and verify operations on each. -t life Set a maximum lifetime when adding identities to an agent. The lifetime may be specified in seconds or in a time format specified in sshd_config(5). -v Verbose mode. Causes ssh-add to print debugging messages about its progress. This is helpful in debugging problems. Multiple -v options increase the verbosity. The maximum is 3. -X Unlock the agent. -x Lock the agent with a password. ENVIRONMENT DISPLAY, SSH_ASKPASS and SSH_ASKPASS_REQUIRE If ssh-add needs a passphrase, it will read the passphrase from the current terminal if it was run from a terminal. If ssh-add does not have a terminal associated with it but DISPLAY and SSH_ASKPASS are set, it will execute the program specified by SSH_ASKPASS (by default M-bM-^@M-^\ssh-askpassM-bM-^@M-^]) and open an X11 window to read the passphrase. This is particularly useful when calling ssh-add from a .xsession or related script. SSH_ASKPASS_REQUIRE allows further control over the use of an askpass program. If this variable is set to M-bM-^@M-^\neverM-bM-^@M-^] then ssh-add will never attempt to use one. If it is set to M-bM-^@M-^\preferM-bM-^@M-^], then ssh-add will prefer to use the askpass program instead of the TTY when requesting passwords. Finally, if the variable is set to M-bM-^@M-^\forceM-bM-^@M-^], then the askpass program will be used for all passphrase input regardless of whether DISPLAY is set. SSH_AUTH_SOCK Identifies the path of a UNIX-domain socket used to communicate with the agent. SSH_SK_PROVIDER Specifies a path to a library that will be used when loading any FIDO authenticator-hosted keys, overriding the default of using the built-in USB HID support. FILES ~/.ssh/id_ecdsa ~/.ssh/id_ecdsa_sk ~/.ssh/id_ed25519 ~/.ssh/id_ed25519_sk ~/.ssh/id_rsa Contains the ECDSA, authenticator-hosted ECDSA, Ed25519, authenticator-hosted Ed25519 or RSA authentication identity of the user. Identity files should not be readable by anyone but the user. Note that ssh-add ignores identity files if they are accessible by others. EXIT STATUS Exit status is 0 on success, 1 if the specified command fails, and 2 if ssh-add is unable to contact the authentication agent.

Through use of environment variables the agent can be located and automatically used for authentication when logging in to other machines using ssh(1). The options are as follows: -a bind_address Bind the agent to the UNIX-domain socket bind_address. The default is $TMPDIR/ssh-XXXXXXXXXX/agent.. -c Generate C-shell commands on stdout. This is the default if SHELL looks like it's a csh style of shell. -D Foreground mode. When this option is specified, ssh-agent will not fork. -d Debug mode. When this option is specified, ssh-agent will not fork and will write debug information to standard error. -E fingerprint_hash Specifies the hash algorithm used when displaying key fingerprints. Valid options are: M-bM-^@M-^\md5M-bM-^@M-^] and M-bM-^@M-^\sha256M-bM-^@M-^]. The default is M-bM-^@M-^\sha256M-bM-^@M-^]. -k Kill the current agent (given by the SSH_AGENT_PID environment variable). -O option Specify an option when starting ssh-agent. Currently two options are supported: allow-remote-pkcs11 and no-restrict-websafe. The allow-remote-pkcs11 option allows clients of a forwarded ssh-agent to load PKCS#11 or FIDO provider libraries. By default only local clients may perform this operation. Note that signalling that an ssh-agent client is remote is performed by ssh(1), and use of other tools to forward access to the agent socket may circumvent this restriction. The no-restrict-websafe option instructs ssh-agent to permit signatures using FIDO keys that might be web authentication requests. By default, ssh-agent refuses signature requests for FIDO keys where the key application string does not start with M-bM-^@M-^\ssh:M-bM-^@M-^] and when the data to be signed does not appear to be a ssh(1) user authentication request or a ssh-keygen(1) signature. The default behaviour prevents forwarded access to a FIDO key from also implicitly forwarding the ability to authenticate to websites. -P allowed_providers Specify a pattern-list of acceptable paths for PKCS#11 provider and FIDO authenticator middleware shared libraries that may be used with the -S or -s options to ssh-add(1). Libraries that do not match the pattern list will be refused. See PATTERNS in ssh_config(5) for a description of pattern-list syntax. The default list is M-bM-^@M-^\usr/lib*/*,/usr/local/lib*/*M-bM-^@M-^]. -s Generate Bourne shell commands on stdout. This is the default if SHELL does not look like it's a csh style of shell. -t life Set a default value for the maximum lifetime of identities added to the agent. The lifetime may be specified in seconds or in a time format specified in sshd_config(5). A lifetime specified for an identity with ssh-add(1) overrides this value. Without this option the default maximum lifetime is forever. command [arg ...] If a command (and optional arguments) is given, this is executed as a subprocess of the agent. The agent exits automatically when the command given on the command line terminates. There are two main ways to get an agent set up. The first is at the start of an X session, where all other windows or programs are started as children of the ssh-agent program. The agent starts a command under which its environment variables are exported, for example ssh-agent xterm &. When the command terminates, so does the agent. The second method is used for a login session. When ssh-agent is started, it prints the shell commands required to set its environment variables, which in turn can be evaluated in the calling shell, for example eval `ssh-agent -s`. In both cases, ssh(1) looks at these environment variables and uses them to establish a connection to the agent. The agent initially does not have any private keys. Keys are added using ssh-add(1) or by ssh(1) when AddKeysToAgent is set in ssh_config(5). Multiple identities may be stored in ssh-agent concurrently and ssh(1) will automatically use them if present. ssh-add(1) is also used to remove keys from ssh-agent and to query the keys that are held in one. Connections to ssh-agent may be forwarded from further remote hosts using the -A option to ssh(1) (but see the caveats documented therein), avoiding the need for authentication data to be stored on other machines. Authentication passphrases and private keys never go over the network: the connection to the agent is forwarded over SSH remote connections and the result is returned to the requester, allowing the user access to their identities anywhere in the network in a secure fashion. ENVIRONMENT SSH_AGENT_PID When ssh-agent starts, it stores the name of the agent's process ID (PID) in this variable. SSH_AUTH_SOCK When ssh-agent starts, it creates a UNIX-domain socket and stores its pathname in this variable. It is accessible only to the current user, but is easily abused by root or another instance of the same user. FILES $TMPDIR/ssh-XXXXXXXXXX/agent. UNIX-domain sockets used to contain the connection to the authentication agent. These sockets should only be readable by the owner. The sockets should get automatically removed when the agent exits.

The type of key to be generated is specified with the -t option. If invoked without any arguments, ssh-keygen will generate an Ed25519 key. ssh-keygen is also used to generate groups for use in Diffie-Hellman group exchange (DH-GEX). See the MODULI GENERATION section for details. Finally, ssh-keygen can be used to generate and update Key Revocation Lists, and to test whether given keys have been revoked by one. See the KEY REVOCATION LISTS section for details. Normally each user wishing to use SSH with public key authentication runs this once to create the authentication key in ~/.ssh/id_ecdsa, ~/.ssh/id_ecdsa_sk, ~/.ssh/id_ed25519, ~/.ssh/id_ed25519_sk or ~/.ssh/id_rsa. Additionally, the system administrator may use this to generate host keys, as seen in /etc/rc. Normally this program generates the key and asks for a file in which to store the private key. The public key is stored in a file with the same name but M-bM-^@M-^\.pubM-bM-^@M-^] appended. The program also asks for a passphrase. The passphrase may be empty to indicate no passphrase (host keys must have an empty passphrase), or it may be a string of arbitrary length. A passphrase is similar to a password, except it can be a phrase with a series of words, punctuation, numbers, whitespace, or any string of characters you want. Good passphrases are 10-30 characters long, are not simple sentences or otherwise easily guessable (English prose has only 1-2 bits of entropy per character, and provides very bad passphrases), and contain a mix of upper and lowercase letters, numbers, and non- alphanumeric characters. The passphrase can be changed later by using the -p option. There is no way to recover a lost passphrase. If the passphrase is lost or forgotten, a new key must be generated and the corresponding public key copied to other machines. ssh-keygen will by default write keys in an OpenSSH-specific format. This format is preferred as it offers better protection for keys at rest as well as allowing storage of key comments within the private key file itself. The key comment may be useful to help identify the key. The comment is initialized to M-bM-^@M-^\user@hostM-bM-^@M-^] when the key is created, but can be changed using the -c option. It is still possible for ssh-keygen to write the previously-used PEM format private keys using the -m flag. This may be used when generating new keys, and existing new-format keys may be converted using this option in conjunction with the -p (change passphrase) flag. After a key is generated, ssh-keygen will ask where the keys should be placed to be activated. The options are as follows: -A Generate host keys of all default key types (rsa, ecdsa, and ed25519) if they do not already exist. The host keys are generated with the default key file path, an empty passphrase, default bits for the key type, and default comment. If -f has also been specified, its argument is used as a prefix to the default path for the resulting host key files. This is used by /etc/rc to generate new host keys. -a rounds When saving a private key, this option specifies the number of KDF (key derivation function, currently bcrypt_pbkdf(3)) rounds used. Higher numbers result in slower passphrase verification and increased resistance to brute-force password cracking (should the keys be stolen). The default is 16 rounds. -B Show the bubblebabble digest of specified private or public key file. -b bits Specifies the number of bits in the key to create. For RSA keys, the minimum size is 1024 bits and the default is 3072 bits. Generally, 3072 bits is considered sufficient. For ECDSA keys, the -b flag determines the key length by selecting from one of three elliptic curve sizes: 256, 384 or 521 bits. Attempting to use bit lengths other than these three values for ECDSA keys will fail. ECDSA-SK, Ed25519 and Ed25519-SK keys have a fixed length and the -b flag will be ignored. -C comment Provides a new comment. -c Requests changing the comment in the private and public key files. The program will prompt for the file containing the private keys, for the passphrase if the key has one, and for the new comment. -D pkcs11 Download the public keys provided by the PKCS#11 shared library pkcs11. When used in combination with -s, this option indicates that a CA key resides in a PKCS#11 token (see the CERTIFICATES section for details). -E fingerprint_hash Specifies the hash algorithm used when displaying key fingerprints. Valid options are: M-bM-^@M-^\md5M-bM-^@M-^] and M-bM-^@M-^\sha256M-bM-^@M-^]. The default is M-bM-^@M-^\sha256M-bM-^@M-^]. -e This option will read a private or public OpenSSH key file and print to stdout a public key in one of the formats specified by the -m option. The default export format is M-bM-^@M-^\RFC4716M-bM-^@M-^]. This option allows exporting OpenSSH keys for use by other programs, including several commercial SSH implementations. -F hostname | [hostname]:port Search for the specified hostname (with optional port number) in a known_hosts file, listing any occurrences found. This option is useful to find hashed host names or addresses and may also be used in conjunction with the -H option to print found keys in a hashed format. -f filename Specifies the filename of the key file. -g Use generic DNS format when printing fingerprint resource records using the -r command. -H Hash a known_hosts file. This replaces all hostnames and addresses with hashed representations within the specified file; the original content is moved to a file with a .old suffix. These hashes may be used normally by ssh and sshd, but they do not reveal identifying information should the file's contents be disclosed. This option will not modify existing hashed hostnames and is therefore safe to use on files that mix hashed and non- hashed names. -h When signing a key, create a host certificate instead of a user certificate. See the CERTIFICATES section for details. -I certificate_identity Specify the key identity when signing a public key. See the CERTIFICATES section for details. -i This option will read an unencrypted private (or public) key file in the format specified by the -m option and print an OpenSSH compatible private (or public) key to stdout. This option allows importing keys from other software, including several commercial SSH implementations. The default import format is M-bM-^@M-^\RFC4716M-bM-^@M-^]. -K Download resident keys from a FIDO authenticator. Public and private key files will be written to the current directory for each downloaded key. If multiple FIDO authenticators are attached, keys will be downloaded from the first touched authenticator. See the FIDO AUTHENTICATOR section for more information. -k Generate a KRL file. In this mode, ssh-keygen will generate a KRL file at the location specified via the -f flag that revokes every key or certificate presented on the command line. Keys/certificates to be revoked may be specified by public key file or using the format described in the KEY REVOCATION LISTS section. -L Prints the contents of one or more certificates. -l Show fingerprint of specified public key file. ssh-keygen will try to find the matching public key file and prints its fingerprint. If combined with -v, a visual ASCII art representation of the key is supplied with the fingerprint. -M generate Generate candidate Diffie-Hellman Group Exchange (DH-GEX) parameters for eventual use by the M-bM-^@M-^Xdiffie-hellman-group-exchange-*M-bM-^@M-^Y key exchange methods. The numbers generated by this operation must be further screened before use. See the MODULI GENERATION section for more information. -M screen Screen candidate parameters for Diffie-Hellman Group Exchange. This will accept a list of candidate numbers and test that they are safe (Sophie Germain) primes with acceptable group generators. The results of this operation may be added to the /etc/moduli file. See the MODULI GENERATION section for more information. -m key_format Specify a key format for key generation, the -i (import), -e (export) conversion options, and the -p change passphrase operation. The latter may be used to convert between OpenSSH private key and PEM private key formats. The supported key formats are: M-bM-^@M-^\RFC4716M-bM-^@M-^] (RFC 4716/SSH2 public or private key), M-bM-^@M-^\PKCS8M-bM-^@M-^] (PKCS8 public or private key) or M-bM-^@M-^\PEMM-bM-^@M-^] (PEM public key). By default OpenSSH will write newly-generated private keys in its own format, but when converting public keys for export the default format is M-bM-^@M-^\RFC4716M-bM-^@M-^]. Setting a format of M-bM-^@M-^\PEMM-bM-^@M-^] when generating or updating a supported private key type will cause the key to be stored in the legacy PEM private key format. -N new_passphrase Provides the new passphrase. -n principals Specify one or more principals (user or host names) to be included in a certificate when signing a key. Multiple principals may be specified, separated by commas. See the CERTIFICATES section for details. -O option Specify a key/value option. These are specific to the operation that ssh-keygen has been requested to perform. When signing certificates, one of the options listed in the CERTIFICATES section may be specified here. When performing moduli generation or screening, one of the options listed in the MODULI GENERATION section may be specified. When generating FIDO authenticator-backed keys, the options listed in the FIDO AUTHENTICATOR section may be specified. When performing signature-related options using the -Y flag, the following options are accepted: hashalg=algorithm Selects the hash algorithm to use for hashing the message to be signed. Valid algorithms are M-bM-^@M-^\sha256M-bM-^@M-^] and M-bM-^@M-^\sha512.M-bM-^@M-^] The default is M-bM-^@M-^\sha512.M-bM-^@M-^] print-pubkey Print the full public key to standard output after signature verification. verify-time=timestamp Specifies a time to use when validating signatures instead of the current time. The time may be specified as a date or time in the YYYYMMDD[Z] or in YYYYMMDDHHMM[SS][Z] formats. Dates and times will be interpreted in the current system time zone unless suffixed with a Z character, which causes them to be interpreted in the UTC time zone. When generating SSHFP DNS records from public keys using the -r flag, the following options are accepted: hashalg=algorithm Selects a hash algorithm to use when printing SSHFP records using the -D flag. Valid algorithms are M-bM-^@M-^\sha1M-bM-^@M-^] and M-bM-^@M-^\sha256M-bM-^@M-^]. The default is to print both. The -O option may be specified multiple times. -P passphrase Provides the (old) passphrase. -p Requests changing the passphrase of a private key file instead of creating a new private key. The program will prompt for the file containing the private key, for the old passphrase, and twice for the new passphrase. -Q Test whether keys have been revoked in a KRL. If the -l option is also specified then the contents of the KRL will be printed. -q Silence ssh-keygen. -R hostname | [hostname]:port Removes all keys belonging to the specified hostname (with optional port number) from a known_hosts file. This option is useful to delete hashed hosts (see the -H option above). -r hostname Print the SSHFP fingerprint resource record named hostname for the specified public key file. -s ca_key Certify (sign) a public key using the specified CA key. See the CERTIFICATES section for details. When generating a KRL, -s specifies a path to a CA public key file used to revoke certificates directly by key ID or serial number. See the KEY REVOCATION LISTS section for details. -t ecdsa | ecdsa-sk | ed25519 | ed25519-sk | rsa Specifies the type of key to create. The possible values are M-bM-^@M-^\ecdsaM-bM-^@M-^], M-bM-^@M-^\ecdsa-skM-bM-^@M-^], M-bM-^@M-^\ed25519 (the default),M-bM-^@M-^] M-bM-^@M-^\ed25519-skM-bM-^@M-^], or M-bM-^@M-^\rsaM-bM-^@M-^]. This flag may also be used to specify the desired signature type when signing certificates using an RSA CA key. The available RSA signature variants are M-bM-^@M-^\ssh-rsaM-bM-^@M-^] (SHA1 signatures, not recommended), M-bM-^@M-^\rsa-sha2-256M-bM-^@M-^], and M-bM-^@M-^\rsa-sha2-512M-bM-^@M-^] (the default for RSA keys). -U When used in combination with -s or -Y sign, this option indicates that a CA key resides in a ssh-agent(1). See the CERTIFICATES section for more information. -u Update a KRL. When specified with -k, keys listed via the command line are added to the existing KRL rather than a new KRL being created. -V validity_interval Specify a validity interval when signing a certificate. A validity interval may consist of a single time, indicating that the certificate is valid beginning now and expiring at that time, or may consist of two times separated by a colon to indicate an explicit time interval. The start time may be specified as: M-bM-^@M-M-bM-^@M-" The string M-bM-^@M-^\alwaysM-bM-^@M-^] to indicate the certificate has no specified start time. M-bM-^@M-M-bM-^@M-" A date or time in the system time zone formatted as YYYYMMDD or YYYYMMDDHHMM[SS]. M-bM-^@M-M-bM-^@M-" A date or time in the UTC time zone as YYYYMMDDZ or YYYYMMDDHHMM[SS]Z. M-bM-^@M-M-bM-^@M-" A relative time before the current system time consisting of a minus sign followed by an interval in the format described in the TIME FORMATS section of sshd_config(5). M-bM-^@M-M-bM-^@M-" A raw seconds since epoch (Jan 1 1970 00:00:00 UTC) as a hexadecimal number beginning with M-bM-^@M-^\0xM-bM-^@M-^]. The end time may be specified similarly to the start time: M-bM-^@M-M-bM-^@M-" The string M-bM-^@M-^\foreverM-bM-^@M-^] to indicate the certificate has no specified end time. M-bM-^@M-M-bM-^@M-" A date or time in the system time zone formatted as YYYYMMDD or YYYYMMDDHHMM[SS]. M-bM-^@M-M-bM-^@M-" A date or time in the UTC time zone as YYYYMMDDZ or YYYYMMDDHHMM[SS]Z. M-bM-^@M-M-bM-^@M-" A relative time after the current system time consisting of a plus sign followed by an interval in the format described in the TIME FORMATS section of sshd_config(5). M-bM-^@M-M-bM-^@M-" A raw seconds since epoch (Jan 1 1970 00:00:00 UTC) as a hexadecimal number beginning with M-bM-^@M-^\0xM-bM-^@M-^]. For example: +52w1d Valid from now to 52 weeks and one day from now. -4w:+4w Valid from four weeks ago to four weeks from now. 20100101123000:20110101123000 Valid from 12:30 PM, January 1st, 2010 to 12:30 PM, January 1st, 2011. 20100101123000Z:20110101123000Z Similar, but interpreted in the UTC time zone rather than the system time zone. -1d:20110101 Valid from yesterday to midnight, January 1st, 2011. 0x1:0x2000000000 Valid from roughly early 1970 to May 2033. -1m:forever Valid from one minute ago and never expiring. -v Verbose mode. Causes ssh-keygen to print debugging messages about its progress. This is helpful for debugging moduli generation. Multiple -v options increase the verbosity. The maximum is 3. -w provider Specifies a path to a library that will be used when creating FIDO authenticator-hosted keys, overriding the default of using the internal USB HID support. -Y find-principals Find the principal(s) associated with the public key of a signature, provided using the -s flag in an authorized signers file provided using the -f flag. The format of the allowed signers file is documented in the ALLOWED SIGNERS section below. If one or more matching principals are found, they are returned on standard output. -Y match-principals Find principal matching the principal name provided using the -I flag in the authorized signers file specified using the -f flag. If one or more matching principals are found, they are returned on standard output. -Y check-novalidate Checks that a signature generated using ssh-keygen -Y sign has a valid structure. This does not validate if a signature comes from an authorized signer. When testing a signature, ssh-keygen accepts a message on standard input and a signature namespace using -n. A file containing the corresponding signature must also be supplied using the -s flag. Successful testing of the signature is signalled by ssh-keygen returning a zero exit status. -Y sign Cryptographically sign a file or some data using an SSH key. When signing, ssh-keygen accepts zero or more files to sign on the command-line - if no files are specified then ssh-keygen will sign data presented on standard input. Signatures are written to the path of the input file with M-bM-^@M-^\.sigM-bM-^@M-^] appended, or to standard output if the message to be signed was read from standard input. The key used for signing is specified using the -f option and may refer to either a private key, or a public key with the private half available via ssh-agent(1). An additional signature namespace, used to prevent signature confusion across different domains of use (e.g. file signing vs email signing) must be provided via the -n flag. Namespaces are arbitrary strings, and may include: M-bM-^@M-^\fileM-bM-^@M-^] for file signing, M-bM-^@M-^\emailM-bM-^@M-^] for email signing. For custom uses, it is recommended to use names following a NAMESPACE@YOUR.DOMAIN pattern to generate unambiguous namespaces. -Y verify Request to verify a signature generated using ssh-keygen -Y sign as described above. When verifying a signature, ssh-keygen accepts a message on standard input and a signature namespace using -n. A file containing the corresponding signature must also be supplied using the -s flag, along with the identity of the signer using -I and a list of allowed signers via the -f flag. The format of the allowed signers file is documented in the ALLOWED SIGNERS section below. A file containing revoked keys can be passed using the -r flag. The revocation file may be a KRL or a one-per-line list of public keys. Successful verification by an authorized signer is signalled by ssh-keygen returning a zero exit status. -y This option will read a private OpenSSH format file and print an OpenSSH public key to stdout. -Z cipher Specifies the cipher to use for encryption when writing an OpenSSH-format private key file. The list of available ciphers may be obtained using "ssh -Q cipher". The default is M-bM-^@M-^\aes256-ctrM-bM-^@M-^]. -z serial_number Specifies a serial number to be embedded in the certificate to distinguish this certificate from others from the same CA. If the serial_number is prefixed with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the serial number will be incremented for each certificate signed on a single command-line. The default serial number is zero. When generating a KRL, the -z flag is used to specify a KRL version number. MODULI GENERATION ssh-keygen may be used to generate groups for the Diffie-Hellman Group Exchange (DH-GEX) protocol. Generating these groups is a two-step process: first, candidate primes are generated using a fast, but memory intensive process. These candidate primes are then tested for suitability (a CPU-intensive process). Generation of primes is performed using the -M generate option. The desired length of the primes may be specified by the -O bits option. For example: # ssh-keygen -M generate -O bits=2048 moduli-2048.candidates By default, the search for primes begins at a random point in the desired length range. This may be overridden using the -O start option, which specifies a different start point (in hex). Once a set of candidates have been generated, they must be screened for suitability. This may be performed using the -M screen option. In this mode ssh-keygen will read candidates from standard input (or a file specified using the -f option). For example: # ssh-keygen -M screen -f moduli-2048.candidates moduli-2048 By default, each candidate will be subjected to 100 primality tests. This may be overridden using the -O prime-tests option. The DH generator value will be chosen automatically for the prime under consideration. If a specific generator is desired, it may be requested using the -O generator option. Valid generator values are 2, 3, and 5. Screened DH groups may be installed in /etc/moduli. It is important that this file contains moduli of a range of bit lengths. A number of options are available for moduli generation and screening via the -O flag: lines=number Exit after screening the specified number of lines while performing DH candidate screening. start-line=line-number Start screening at the specified line number while performing DH candidate screening. checkpoint=filename Write the last line processed to the specified file while performing DH candidate screening. This will be used to skip lines in the input file that have already been processed if the job is restarted. memory=mbytes Specify the amount of memory to use (in megabytes) when generating candidate moduli for DH-GEX. start=hex-value Specify start point (in hex) when generating candidate moduli for DH-GEX. generator=value Specify desired generator (in decimal) when testing candidate moduli for DH-GEX. CERTIFICATES ssh-keygen supports signing of keys to produce certificates that may be used for user or host authentication. Certificates consist of a public key, some identity information, zero or more principal (user or host) names and a set of options that are signed by a Certification Authority (CA) key. Clients or servers may then trust only the CA key and verify its signature on a certificate rather than trusting many user/host keys. Note that OpenSSH certificates are a different, and much simpler, format to the X.509 certificates used in ssl(8). ssh-keygen supports two types of certificates: user and host. User certificates authenticate users to servers, whereas host certificates authenticate server hosts to users. To generate a user certificate: $ ssh-keygen -s /path/to/ca_key -I key_id /path/to/user_key.pub The resultant certificate will be placed in /path/to/user_key-cert.pub. A host certificate requires the -h option: $ ssh-keygen -s /path/to/ca_key -I key_id -h /path/to/host_key.pub The host certificate will be output to /path/to/host_key-cert.pub. It is possible to sign using a CA key stored in a PKCS#11 token by providing the token library using -D and identifying the CA key by providing its public half as an argument to -s: $ ssh-keygen -s ca_key.pub -D libpkcs11.so -I key_id user_key.pub Similarly, it is possible for the CA key to be hosted in a ssh-agent(1). This is indicated by the -U flag and, again, the CA key must be identified by its public half. $ ssh-keygen -Us ca_key.pub -I key_id user_key.pub In all cases, key_id is a "key identifier" that is logged by the server when the certificate is used for authentication. Certificates may be limited to be valid for a set of principal (user/host) names. By default, generated certificates are valid for all users or hosts. To generate a certificate for a specified set of principals: $ ssh-keygen -s ca_key -I key_id -n user1,user2 user_key.pub $ ssh-keygen -s ca_key -I key_id -h -n host.domain host_key.pub Additional limitations on the validity and use of user certificates may be specified through certificate options. A certificate option may disable features of the SSH session, may be valid only when presented from particular source addresses or may force the use of a specific command. The options that are valid for user certificates are: clear Clear all enabled permissions. This is useful for clearing the default set of permissions so permissions may be added individually. critical:name[=contents] extension:name[=contents] Includes an arbitrary certificate critical option or extension. The specified name should include a domain suffix, e.g. M-bM-^@M-^\name@example.comM-bM-^@M-^]. If contents is specified then it is included as the contents of the extension/option encoded as a string, otherwise the extension/option is created with no contents (usually indicating a flag). Extensions may be ignored by a client or server that does not recognise them, whereas unknown critical options will cause the certificate to be refused. force-command=command Forces the execution of command instead of any shell or command specified by the user when the certificate is used for authentication. no-agent-forwarding Disable ssh-agent(1) forwarding (permitted by default). no-port-forwarding Disable port forwarding (permitted by default). no-pty Disable PTY allocation (permitted by default). no-user-rc Disable execution of ~/.ssh/rc by sshd(8) (permitted by default). no-x11-forwarding Disable X11 forwarding (permitted by default). permit-agent-forwarding Allows ssh-agent(1) forwarding. permit-port-forwarding Allows port forwarding. permit-pty Allows PTY allocation. permit-user-rc Allows execution of ~/.ssh/rc by sshd(8). permit-X11-forwarding Allows X11 forwarding. no-touch-required Do not require signatures made using this key include demonstration of user presence (e.g. by having the user touch the authenticator). This option only makes sense for the FIDO authenticator algorithms ecdsa-sk and ed25519-sk. source-address=address_list Restrict the source addresses from which the certificate is considered valid. The address_list is a comma-separated list of one or more address/netmask pairs in CIDR format. verify-required Require signatures made using this key indicate that the user was first verified. This option only makes sense for the FIDO authenticator algorithms ecdsa-sk and ed25519-sk. Currently PIN authentication is the only supported verification method, but other methods may be supported in the future. At present, no standard options are valid for host keys. Finally, certificates may be defined with a validity lifetime. The -V option allows specification of certificate start and end times. A certificate that is presented at a time outside this range will not be considered valid. By default, certificates are valid from the UNIX Epoch to the distant future. For certificates to be used for user or host authentication, the CA public key must be trusted by sshd(8) or ssh(1). Refer to those manual pages for details. FIDO AUTHENTICATOR ssh-keygen is able to generate FIDO authenticator-backed keys, after which they may be used much like any other key type supported by OpenSSH, so long as the hardware authenticator is attached when the keys are used. FIDO authenticators generally require the user to explicitly authorise operations by touching or tapping them. FIDO keys consist of two parts: a key handle part stored in the private key file on disk, and a per- device private key that is unique to each FIDO authenticator and that cannot be exported from the authenticator hardware. These are combined by the hardware at authentication time to derive the real key that is used to sign authentication challenges. Supported key types are ecdsa-sk and ed25519-sk. The options that are valid for FIDO keys are: application Override the default FIDO application/origin string of M-bM-^@M-^\ssh:M-bM-^@M-^]. This may be useful when generating host or domain-specific resident keys. The specified application string must begin with M-bM-^@M-^\ssh:M-bM-^@M-^]. challenge=path Specifies a path to a challenge string that will be passed to the FIDO authenticator during key generation. The challenge string may be used as part of an out-of-band protocol for key enrollment (a random challenge is used by default). device Explicitly specify a fido(4) device to use, rather than letting the authenticator middleware select one. no-touch-required Indicate that the generated private key should not require touch events (user presence) when making signatures. Note that sshd(8) will refuse such signatures by default, unless overridden via an authorized_keys option. resident Indicate that the key handle should be stored on the FIDO authenticator itself. This makes it easier to use the authenticator on multiple computers. Resident keys may be supported on FIDO2 authenticators and typically require that a PIN be set on the authenticator prior to generation. Resident keys may be loaded off the authenticator using ssh-add(1). Storing both parts of a key on a FIDO authenticator increases the likelihood of an attacker being able to use a stolen authenticator device. user A username to be associated with a resident key, overriding the empty default username. Specifying a username may be useful when generating multiple resident keys for the same application name. verify-required Indicate that this private key should require user verification for each signature. Not all FIDO authenticators support this option. Currently PIN authentication is the only supported verification method, but other methods may be supported in the future. write-attestation=path May be used at key generation time to record the attestation data returned from FIDO authenticators during key generation. This information is potentially sensitive. By default, this information is discarded. KEY REVOCATION LISTS ssh-keygen is able to manage OpenSSH format Key Revocation Lists (KRLs). These binary files specify keys or certificates to be revoked using a compact format, taking as little as one bit per certificate if they are being revoked by serial number. KRLs may be generated using the -k flag. This option reads one or more files from the command line and generates a new KRL. The files may either contain a KRL specification (see below) or public keys, listed one per line. Plain public keys are revoked by listing their hash or contents in the KRL and certificates revoked by serial number or key ID (if the serial is zero or not available). Revoking keys using a KRL specification offers explicit control over the types of record used to revoke keys and may be used to directly revoke certificates by serial number or key ID without having the complete original certificate on hand. A KRL specification consists of lines containing one of the following directives followed by a colon and some directive-specific information. serial: serial_number[-serial_number] Revokes a certificate with the specified serial number. Serial numbers are 64-bit values, not including zero and may be expressed in decimal, hex or octal. If two serial numbers are specified separated by a hyphen, then the range of serial numbers including and between each is revoked. The CA key must have been specified on the ssh-keygen command line using the -s option. id: key_id Revokes a certificate with the specified key ID string. The CA key must have been specified on the ssh-keygen command line using the -s option. key: public_key Revokes the specified key. If a certificate is listed, then it is revoked as a plain public key. sha1: public_key Revokes the specified key by including its SHA1 hash in the KRL. sha256: public_key Revokes the specified key by including its SHA256 hash in the KRL. KRLs that revoke keys by SHA256 hash are not supported by OpenSSH versions prior to 7.9. hash: fingerprint Revokes a key using a fingerprint hash, as obtained from a sshd(8) authentication log message or the ssh-keygen -l flag. Only SHA256 fingerprints are supported here and resultant KRLs are not supported by OpenSSH versions prior to 7.9. KRLs may be updated using the -u flag in addition to -k. When this option is specified, keys listed via the command line are merged into the KRL, adding to those already there. It is also possible, given a KRL, to test whether it revokes a particular key (or keys). The -Q flag will query an existing KRL, testing each key specified on the command line. If any key listed on the command line has been revoked (or an error encountered) then ssh-keygen will exit with a non-zero exit status. A zero exit status will only be returned if no key was revoked. ALLOWED SIGNERS When verifying signatures, ssh-keygen uses a simple list of identities and keys to determine whether a signature comes from an authorized source. This "allowed signers" file uses a format patterned after the AUTHORIZED_KEYS FILE FORMAT described in sshd(8). Each line of the file contains the following space-separated fields: principals, options, keytype, base64-encoded key. Empty lines and lines starting with a M-bM-^@M-^X#M-bM-^@M-^Y are ignored as comments. The principals field is a pattern-list (see PATTERNS in ssh_config(5)) consisting of one or more comma-separated USER@DOMAIN identity patterns that are accepted for signing. When verifying, the identity presented via the -I option must match a principals pattern in order for the corresponding key to be considered acceptable for verification. The options (if present) consist of comma-separated option specifications. No spaces are permitted, except within double quotes. The following option specifications are supported (note that option keywords are case-insensitive): cert-authority Indicates that this key is accepted as a certificate authority (CA) and that certificates signed by this CA may be accepted for verification. namespaces=namespace-list Specifies a pattern-list of namespaces that are accepted for this key. If this option is present, the signature namespace embedded in the signature object and presented on the verification command-line must match the specified list before the key will be considered acceptable. valid-after=timestamp Indicates that the key is valid for use at or after the specified timestamp, which may be a date or time in the YYYYMMDD[Z] or YYYYMMDDHHMM[SS][Z] formats. Dates and times will be interpreted in the current system time zone unless suffixed with a Z character, which causes them to be interpreted in the UTC time zone. valid-before=timestamp Indicates that the key is valid for use at or before the specified timestamp. When verifying signatures made by certificates, the expected principal name must match both the principals pattern in the allowed signers file and the principals embedded in the certificate itself. An example allowed signers file: # Comments allowed at start of line user1@example.com,user2@example.com ssh-rsa AAAAX1... # A certificate authority, trusted for all principals in a domain. *@example.com cert-authority ssh-ed25519 AAAB4... # A key that is accepted only for file signing. user2@example.com namespaces="file" ssh-ed25519 AAA41... ENVIRONMENT SSH_SK_PROVIDER Specifies a path to a library that will be used when loading any FIDO authenticator-hosted keys, overriding the default of using the built-in USB HID support. FILES ~/.ssh/id_ecdsa ~/.ssh/id_ecdsa_sk ~/.ssh/id_ed25519 ~/.ssh/id_ed25519_sk ~/.ssh/id_rsa Contains the ECDSA, authenticator-hosted ECDSA, Ed25519, authenticator-hosted Ed25519 or RSA authentication identity of the user. This file should not be readable by anyone but the user. It is possible to specify a passphrase when generating the key; that passphrase will be used to encrypt the private part of this file using 128-bit AES. This file is not automatically accessed by ssh-keygen but it is offered as the default file for the private key. ssh(1) will read this file when a login attempt is made. ~/.ssh/id_ecdsa.pub ~/.ssh/id_ecdsa_sk.pub ~/.ssh/id_ed25519.pub ~/.ssh/id_ed25519_sk.pub ~/.ssh/id_rsa.pub Contains the ECDSA, authenticator-hosted ECDSA, Ed25519, authenticator-hosted Ed25519 or RSA public key for authentication. The contents of this file should be added to ~/.ssh/authorized_keys on all machines where the user wishes to log in using public key authentication. There is no need to keep the contents of this file secret. /etc/moduli Contains Diffie-Hellman groups used for DH-GEX. The file format is described in moduli(5).

It was designed to aid in building and verifying ssh_known_hosts files, the format of which is documented in sshd(8). ssh-keyscan provides a minimal interface suitable for use by shell and perl scripts. ssh-keyscan uses non-blocking socket I/O to contact as many hosts as possible in parallel, so it is very efficient. The keys from a domain of 1,000 hosts can be collected in tens of seconds, even when some of those hosts are down or do not run sshd(8). For scanning, one does not need login access to the machines that are being scanned, nor does the scanning process involve any encryption. Hosts to be scanned may be specified by hostname, address or by CIDR network range (e.g. 192.168.16/28). If a network range is specified, then all addresses in that range will be scanned. The options are as follows: -4 Force ssh-keyscan to use IPv4 addresses only. -6 Force ssh-keyscan to use IPv6 addresses only. -c Request certificates from target hosts instead of plain keys. -D Print keys found as SSHFP DNS records. The default is to print keys in a format usable as a ssh(1) known_hosts file. -f file Read hosts or M-bM-^@M-^\addrlist namelistM-bM-^@M-^] pairs from file, one per line. If M-bM-^@M-^X-M-bM-^@M-^Y is supplied instead of a filename, ssh-keyscan will read from the standard input. Names read from a file must start with an address, hostname or CIDR network range to be scanned. Addresses and hostnames may optionally be followed by comma- separated name or address aliases that will be copied to the output. For example: 192.168.11.0/24 10.20.1.1 happy.example.org 10.0.0.1,sad.example.org -H Hash all hostnames and addresses in the output. Hashed names may be used normally by ssh(1) and sshd(8), but they do not reveal identifying information should the file's contents be disclosed. -O option Specify a key/value option. At present, only a single option is supported: hashalg=algorithm Selects a hash algorithm to use when printing SSHFP records using the -D flag. Valid algorithms are M-bM-^@M-^\sha1M-bM-^@M-^] and M-bM-^@M-^\sha256M-bM-^@M-^]. The default is to print both. -p port Connect to port on the remote host. -q Quiet mode: do not print server host name and banners in comments. -T timeout Set the timeout for connection attempts. If timeout seconds have elapsed since a connection was initiated to a host or since the last time anything was read from that host, the connection is closed and the host in question considered unavailable. The default is 5 seconds. -t type Specify the type of the key to fetch from the scanned hosts. The possible values are M-bM-^@M-^\ecdsaM-bM-^@M-^], M-bM-^@M-^\ed25519M-bM-^@M-^], M-bM-^@M-^\ecdsa-skM-bM-^@M-^], M-bM-^@M-^\ed25519-skM-bM-^@M-^], or M-bM-^@M-^\rsaM-bM-^@M-^]. Multiple values may be specified by separating them with commas. The default is to fetch all the above key types. -v Verbose mode: print debugging messages about progress. If an ssh_known_hosts file is constructed using ssh-keyscan without verifying the keys, users will be vulnerable to man in the middle attacks. On the other hand, if the security model allows such a risk, ssh-keyscan can help in the detection of tampered keyfiles or man in the middle attacks which have begun after the ssh_known_hosts file was created.

It is intended to provide secure encrypted communications between two untrusted hosts over an insecure network. X11 connections, arbitrary TCP ports and UNIX-domain sockets can also be forwarded over the secure channel. ssh connects and logs into the specified destination, which may be specified as either [user@]hostname or a URI of the form ssh://[user@]hostname[:port]. The user must prove their identity to the remote machine using one of several methods (see below). If a command is specified, it will be executed on the remote host instead of a login shell. A complete command line may be specified as command, or it may have additional arguments. If supplied, the arguments will be appended to the command, separated by spaces, before it is sent to the server to be executed. The options are as follows: -4 Forces ssh to use IPv4 addresses only. -6 Forces ssh to use IPv6 addresses only. -A Enables forwarding of connections from an authentication agent such as ssh-agent(1). This can also be specified on a per-host basis in a configuration file. Agent forwarding should be enabled with caution. Users with the ability to bypass file permissions on the remote host (for the agent's UNIX-domain socket) can access the local agent through the forwarded connection. An attacker cannot obtain key material from the agent, however they can perform operations on the keys that enable them to authenticate using the identities loaded into the agent. A safer alternative may be to use a jump host (see -J). -a Disables forwarding of the authentication agent connection. -B bind_interface Bind to the address of bind_interface before attempting to connect to the destination host. This is only useful on systems with more than one address. -b bind_address Use bind_address on the local machine as the source address of the connection. Only useful on systems with more than one address. -C Requests compression of all data (including stdin, stdout, stderr, and data for forwarded X11, TCP and UNIX-domain connections). The compression algorithm is the same used by gzip(1). Compression is desirable on modem lines and other slow connections, but will only slow down things on fast networks. The default value can be set on a host-by-host basis in the configuration files; see the Compression option in ssh_config(5). -c cipher_spec Selects the cipher specification for encrypting the session. cipher_spec is a comma-separated list of ciphers listed in order of preference. See the Ciphers keyword in ssh_config(5) for more information. -D [bind_address:]port Specifies a local M-bM-^@M-^\dynamicM-bM-^@M-^] application-level port forwarding. This works by allocating a socket to listen to port on the local side, optionally bound to the specified bind_address. Whenever a connection is made to this port, the connection is forwarded over the secure channel, and the application protocol is then used to determine where to connect to from the remote machine. Currently the SOCKS4 and SOCKS5 protocols are supported, and ssh will act as a SOCKS server. Only root can forward privileged ports. Dynamic port forwardings can also be specified in the configuration file. IPv6 addresses can be specified by enclosing the address in square brackets. Only the superuser can forward privileged ports. By default, the local port is bound in accordance with the GatewayPorts setting. However, an explicit bind_address may be used to bind the connection to a specific address. The bind_address of M-bM-^@M-^\localhostM-bM-^@M-^] indicates that the listening port be bound for local use only, while an empty address or M-bM-^@M-^X*M-bM-^@M-^Y indicates that the port should be available from all interfaces. -E log_file Append debug logs to log_file instead of standard error. -e escape_char Sets the escape character for sessions with a pty (default: M-bM-^@M-^X~M-bM-^@M-^Y). The escape character is only recognized at the beginning of a line. The escape character followed by a dot (M-bM-^@M-^X.M-bM-^@M-^Y) closes the connection; followed by control-Z suspends the connection; and followed by itself sends the escape character once. Setting the character to M-bM-^@M-^\noneM-bM-^@M-^] disables any escapes and makes the session fully transparent. -F configfile Specifies an alternative per-user configuration file. If a configuration file is given on the command line, the system-wide configuration file (/etc/ssh/ssh_config) will be ignored. The default for the per-user configuration file is ~/.ssh/config. If set to M-bM-^@M-^\noneM-bM-^@M-^], no configuration files will be read. -f Requests ssh to go to background just before command execution. This is useful if ssh is going to ask for passwords or passphrases, but the user wants it in the background. This implies -n. The recommended way to start X11 programs at a remote site is with something like ssh -f host xterm. If the ExitOnForwardFailure configuration option is set to M-bM-^@M-^\yesM-bM-^@M-^], then a client started with -f will wait for all remote port forwards to be successfully established before placing itself in the background. Refer to the description of ForkAfterAuthentication in ssh_config(5) for details. -G Causes ssh to print its configuration after evaluating Host and Match blocks and exit. -g Allows remote hosts to connect to local forwarded ports. If used on a multiplexed connection, then this option must be specified on the master process. -I pkcs11 Specify the PKCS#11 shared library ssh should use to communicate with a PKCS#11 token providing keys for user authentication. -i identity_file Selects a file from which the identity (private key) for public key authentication is read. You can also specify a public key file to use the corresponding private key that is loaded in ssh-agent(1) when the private key file is not present locally. The default is ~/.ssh/id_rsa, ~/.ssh/id_ecdsa, ~/.ssh/id_ecdsa_sk, ~/.ssh/id_ed25519 and ~/.ssh/id_ed25519_sk. Identity files may also be specified on a per-host basis in the configuration file. It is possible to have multiple -i options (and multiple identities specified in configuration files). If no certificates have been explicitly specified by the CertificateFile directive, ssh will also try to load certificate information from the filename obtained by appending -cert.pub to identity filenames. -J destination Connect to the target host by first making an ssh connection to the jump host described by destination and then establishing a TCP forwarding to the ultimate destination from there. Multiple jump hops may be specified separated by comma characters. IPv6 addresses can be specified by enclosing the address in square brackets. This is a shortcut to specify a ProxyJump configuration directive. Note that configuration directives supplied on the command-line generally apply to the destination host and not any specified jump hosts. Use ~/.ssh/config to specify configuration for jump hosts. -K Enables GSSAPI-based authentication and forwarding (delegation) of GSSAPI credentials to the server. -k Disables forwarding (delegation) of GSSAPI credentials to the server. -L [bind_address:]port:host:hostport -L [bind_address:]port:remote_socket -L local_socket:host:hostport -L local_socket:remote_socket Specifies that connections to the given TCP port or Unix socket on the local (client) host are to be forwarded to the given host and port, or Unix socket, on the remote side. This works by allocating a socket to listen to either a TCP port on the local side, optionally bound to the specified bind_address, or to a Unix socket. Whenever a connection is made to the local port or socket, the connection is forwarded over the secure channel, and a connection is made to either host port hostport, or the Unix socket remote_socket, from the remote machine. Port forwardings can also be specified in the configuration file. Only the superuser can forward privileged ports. IPv6 addresses can be specified by enclosing the address in square brackets. By default, the local port is bound in accordance with the GatewayPorts setting. However, an explicit bind_address may be used to bind the connection to a specific address. The bind_address of M-bM-^@M-^\localhostM-bM-^@M-^] indicates that the listening port be bound for local use only, while an empty address or M-bM-^@M-^X*M-bM-^@M-^Y indicates that the port should be available from all interfaces. -l login_name Specifies the user to log in as on the remote machine. This also may be specified on a per-host basis in the configuration file. -M Places the ssh client into M-bM-^@M-^\masterM-bM-^@M-^] mode for connection sharing. Multiple -M options places ssh into M-bM-^@M-^\masterM-bM-^@M-^] mode but with confirmation required using ssh-askpass(1) before each operation that changes the multiplexing state (e.g. opening a new session). Refer to the description of ControlMaster in ssh_config(5) for details. -m mac_spec A comma-separated list of MAC (message authentication code) algorithms, specified in order of preference. See the MACs keyword in ssh_config(5) for more information. -N Do not execute a remote command. This is useful for just forwarding ports. Refer to the description of SessionType in ssh_config(5) for details. -n Redirects stdin from /dev/null (actually, prevents reading from stdin). This must be used when ssh is run in the background. A common trick is to use this to run X11 programs on a remote machine. For example, ssh -n shadows.cs.hut.fi emacs & will start an emacs on shadows.cs.hut.fi, and the X11 connection will be automatically forwarded over an encrypted channel. The ssh program will be put in the background. (This does not work if ssh needs to ask for a password or passphrase; see also the -f option.) Refer to the description of StdinNull in ssh_config(5) for details. -O ctl_cmd Control an active connection multiplexing master process. When the -O option is specified, the ctl_cmd argument is interpreted and passed to the master process. Valid commands are: M-bM-^@M-^\checkM-bM-^@M-^] (check that the master process is running), M-bM-^@M-^\forwardM-bM-^@M-^] (request forwardings without command execution), M-bM-^@M-^\cancelM-bM-^@M-^] (cancel forwardings), M-bM-^@M-^\proxyM-bM-^@M-^] (connect to a running multiplexing master in proxy mode), M-bM-^@M-^\exitM-bM-^@M-^] (request the master to exit), and M-bM-^@M-^\stopM-bM-^@M-^] (request the master to stop accepting further multiplexing requests). -o option Can be used to give options in the format used in the configuration file. This is useful for specifying options for which there is no separate command-line flag. For full details of the options listed below, and their possible values, see ssh_config(5).

Refer to the Tag and Match keywords in ssh_config(5) for more information. -p port Port to connect to on the remote host. This can be specified on a per-host basis in the configuration file. -Q query_option Queries for the algorithms supported by one of the following features: cipher (supported symmetric ciphers), cipher-auth (supported symmetric ciphers that support authenticated encryption), help (supported query terms for use with the -Q flag), mac (supported message integrity codes), kex (key exchange algorithms), key (key types), key-ca-sign (valid CA signature algorithms for certificates), key-cert (certificate key types), key-plain (non-certificate key types), key-sig (all key types and signature algorithms), protocol-version (supported SSH protocol versions), and sig (supported signature algorithms). Alternatively, any keyword from ssh_config(5) or sshd_config(5) that takes an algorithm list may be used as an alias for the corresponding query_option. -q Quiet mode. Causes most warning and diagnostic messages to be suppressed. -R [bind_address:]port:host:hostport -R [bind_address:]port:local_socket -R remote_socket:host:hostport -R remote_socket:local_socket -R [bind_address:]port Specifies that connections to the given TCP port or Unix socket on the remote (server) host are to be forwarded to the local side. This works by allocating a socket to listen to either a TCP port or to a Unix socket on the remote side. Whenever a connection is made to this port or Unix socket, the connection is forwarded over the secure channel, and a connection is made from the local machine to either an explicit destination specified by host port hostport, or local_socket, or, if no explicit destination was specified, ssh will act as a SOCKS 4/5 proxy and forward connections to the destinations requested by the remote SOCKS client. Port forwardings can also be specified in the configuration file. Privileged ports can be forwarded only when logging in as root on the remote machine. IPv6 addresses can be specified by enclosing the address in square brackets. By default, TCP listening sockets on the server will be bound to the loopback interface only. This may be overridden by specifying a bind_address. An empty bind_address, or the address M-bM-^@M-^X*M-bM-^@M-^Y, indicates that the remote socket should listen on all interfaces. Specifying a remote bind_address will only succeed if the server's GatewayPorts option is enabled (see sshd_config(5)). If the port argument is M-bM-^@M-^X0M-bM-^@M-^Y, the listen port will be dynamically allocated on the server and reported to the client at run time. When used together with -O forward, the allocated port will be printed to the standard output. -S ctl_path Specifies the location of a control socket for connection sharing, or the string M-bM-^@M-^\noneM-bM-^@M-^] to disable connection sharing. Refer to the description of ControlPath and ControlMaster in ssh_config(5) for details. -s May be used to request invocation of a subsystem on the remote system. Subsystems facilitate the use of SSH as a secure transport for other applications (e.g. sftp(1)). The subsystem is specified as the remote command. Refer to the description of SessionType in ssh_config(5) for details. -T Disable pseudo-terminal allocation. -t Force pseudo-terminal allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing menu services. Multiple -t options force tty allocation, even if ssh has no local tty. -V Display the version number and exit. -v Verbose mode. Causes ssh to print debugging messages about its progress. This is helpful in debugging connection, authentication, and configuration problems. Multiple -v options increase the verbosity. The maximum is 3. -W host:port Requests that standard input and output on the client be forwarded to host on port over the secure channel. Implies -N, -T, ExitOnForwardFailure and ClearAllForwardings, though these can be overridden in the configuration file or using -o command line options. -w local_tun[:remote_tun] Requests tunnel device forwarding with the specified tun(4) devices between the client (local_tun) and the server (remote_tun). The devices may be specified by numerical ID or the keyword M-bM-^@M-^\anyM-bM-^@M-^], which uses the next available tunnel device. If remote_tun is not specified, it defaults to M-bM-^@M-^\anyM-bM-^@M-^]. See also the Tunnel and TunnelDevice directives in ssh_config(5). If the Tunnel directive is unset, it will be set to the default tunnel mode, which is M-bM-^@M-^\point-to-pointM-bM-^@M-^]. If a different Tunnel forwarding mode it desired, then it should be specified before -w. -X Enables X11 forwarding. This can also be specified on a per-host basis in a configuration file. X11 forwarding should be enabled with caution. Users with the ability to bypass file permissions on the remote host (for the user's X authorization database) can access the local X11 display through the forwarded connection. An attacker may then be able to perform activities such as keystroke monitoring. For this reason, X11 forwarding is subjected to X11 SECURITY extension restrictions by default. Refer to the ssh -Y option and the ForwardX11Trusted directive in ssh_config(5) for more information. -x Disables X11 forwarding. -Y Enables trusted X11 forwarding. Trusted X11 forwardings are not subjected to the X11 SECURITY extension controls. -y Send log information using the syslog(3) system module. By default this information is sent to stderr. ssh may additionally obtain configuration data from a per-user configuration file and a system-wide configuration file. The file format and configuration options are described in ssh_config(5). AUTHENTICATION The OpenSSH SSH client supports SSH protocol 2. The methods available for authentication are: GSSAPI-based authentication, host-based authentication, public key authentication, keyboard-interactive authentication, and password authentication. Authentication methods are tried in the order specified above, though PreferredAuthentications can be used to change the default order. Host-based authentication works as follows: If the machine the user logs in from is listed in /etc/hosts.equiv or /etc/shosts.equiv on the remote machine, the user is non-root and the user names are the same on both sides, or if the files ~/.rhosts or ~/.shosts exist in the user's home directory on the remote machine and contain a line containing the name of the client machine and the name of the user on that machine, the user is considered for login. Additionally, the server must be able to verify the client's host key (see the description of /etc/ssh/ssh_known_hosts and ~/.ssh/known_hosts, below) for login to be permitted. This authentication method closes security holes due to IP spoofing, DNS spoofing, and routing spoofing. [Note to the administrator: /etc/hosts.equiv, ~/.rhosts, and the rlogin/rsh protocol in general, are inherently insecure and should be disabled if security is desired.] Public key authentication works as follows: The scheme is based on public-key cryptography, using cryptosystems where encryption and decryption are done using separate keys, and it is unfeasible to derive the decryption key from the encryption key. The idea is that each user creates a public/private key pair for authentication purposes. The server knows the public key, and only the user knows the private key. ssh implements public key authentication protocol automatically, using one of the ECDSA, Ed25519 or RSA algorithms. The file ~/.ssh/authorized_keys lists the public keys that are permitted for logging in. When the user logs in, the ssh program tells the server which key pair it would like to use for authentication. The client proves that it has access to the private key and the server checks that the corresponding public key is authorized to accept the account. The server may inform the client of errors that prevented public key authentication from succeeding after authentication completes using a different method. These may be viewed by increasing the LogLevel to DEBUG or higher (e.g. by using the -v flag). The user creates their key pair by running ssh-keygen(1). This stores the private key in ~/.ssh/id_ecdsa (ECDSA), ~/.ssh/id_ecdsa_sk (authenticator-hosted ECDSA), ~/.ssh/id_ed25519 (Ed25519), ~/.ssh/id_ed25519_sk (authenticator-hosted Ed25519), or ~/.ssh/id_rsa (RSA) and stores the public key in ~/.ssh/id_ecdsa.pub (ECDSA), ~/.ssh/id_ecdsa_sk.pub (authenticator-hosted ECDSA), ~/.ssh/id_ed25519.pub (Ed25519), ~/.ssh/id_ed25519_sk.pub (authenticator- hosted Ed25519), or ~/.ssh/id_rsa.pub (RSA) in the user's home directory. The user should then copy the public key to ~/.ssh/authorized_keys in their home directory on the remote machine. The authorized_keys file corresponds to the conventional ~/.rhosts file, and has one key per line, though the lines can be very long. After this, the user can log in without giving the password. A variation on public key authentication is available in the form of certificate authentication: instead of a set of public/private keys, signed certificates are used. This has the advantage that a single trusted certification authority can be used in place of many public/private keys. See the CERTIFICATES section of ssh-keygen(1) for more information. The most convenient way to use public key or certificate authentication may be with an authentication agent. See ssh-agent(1) and (optionally) the AddKeysToAgent directive in ssh_config(5) for more information. Keyboard-interactive authentication works as follows: The server sends an arbitrary "challenge" text and prompts for a response, possibly multiple times. Examples of keyboard-interactive authentication include BSD Authentication (see login.conf(5)) and PAM (some non-OpenBSD systems). Finally, if other authentication methods fail, ssh prompts the user for a password. The password is sent to the remote host for checking; however, since all communications are encrypted, the password cannot be seen by someone listening on the network. ssh automatically maintains and checks a database containing identification for all hosts it has ever been used with. Host keys are stored in ~/.ssh/known_hosts in the user's home directory. Additionally, the file /etc/ssh/ssh_known_hosts is automatically checked for known hosts. Any new hosts are automatically added to the user's file. If a host's identification ever changes, ssh warns about this and disables password authentication to prevent server spoofing or man-in-the-middle attacks, which could otherwise be used to circumvent the encryption. The StrictHostKeyChecking option can be used to control logins to machines whose host key is not known or has changed. When the user's identity has been accepted by the server, the server either executes the given command in a non-interactive session or, if no command has been specified, logs into the machine and gives the user a normal shell as an interactive session. All communication with the remote command or shell will be automatically encrypted. If an interactive session is requested, ssh by default will only request a pseudo-terminal (pty) for interactive sessions when the client has one. The flags -T and -t can be used to override this behaviour. If a pseudo-terminal has been allocated, the user may use the escape characters noted below. If no pseudo-terminal has been allocated, the session is transparent and can be used to reliably transfer binary data. On most systems, setting the escape character to M-bM-^@M-^\noneM-bM-^@M-^] will also make the session transparent even if a tty is used. The session terminates when the command or shell on the remote machine exits and all X11 and TCP connections have been closed. ESCAPE CHARACTERS When a pseudo-terminal has been requested, ssh supports a number of functions through the use of an escape character. A single tilde character can be sent as ~~ or by following the tilde by a character other than those described below. The escape character must always follow a newline to be interpreted as special. The escape character can be changed in configuration files using the EscapeChar configuration directive or on the command line by the -e option. The supported escapes (assuming the default M-bM-^@M-^X~M-bM-^@M-^Y) are: ~. Disconnect. ~^Z Background ssh. ~# List forwarded connections. ~& Background ssh at logout when waiting for forwarded connection / X11 sessions to terminate. ~? Display a list of escape characters. ~B Send a BREAK to the remote system (only useful if the peer supports it). ~C Open command line. Currently this allows the addition of port forwardings using the -L, -R and -D options (see above). It also allows the cancellation of existing port-forwardings with -KL[bind_address:]port for local, -KR[bind_address:]port for remote and -KD[bind_address:]port for dynamic port-forwardings. !command allows the user to execute a local command if the PermitLocalCommand option is enabled in ssh_config(5). Basic help is available, using the -h option. ~R Request rekeying of the connection (only useful if the peer supports it). ~V Decrease the verbosity (LogLevel) when errors are being written to stderr. ~v Increase the verbosity (LogLevel) when errors are being written to stderr. TCP FORWARDING Forwarding of arbitrary TCP connections over a secure channel can be specified either on the command line or in a configuration file. One possible application of TCP forwarding is a secure connection to a mail server; another is going through firewalls. In the example below, we look at encrypting communication for an IRC client, even though the IRC server it connects to does not directly support encrypted communication. This works as follows: the user connects to the remote host using ssh, specifying the ports to be used to forward the connection. After that it is possible to start the program locally, and ssh will encrypt and forward the connection to the remote server. The following example tunnels an IRC session from the client to an IRC server at M-bM-^@M-^\server.example.comM-bM-^@M-^], joining channel M-bM-^@M-^\#usersM-bM-^@M-^], nickname M-bM-^@M-^\pinkyM-bM-^@M-^], using the standard IRC port, 6667: $ ssh -f -L 6667:localhost:6667 server.example.com sleep 10 $ irc -c '#users' pinky IRC/127.0.0.1 The -f option backgrounds ssh and the remote command M-bM-^@M-^\sleep 10M-bM-^@M-^] is specified to allow an amount of time (10 seconds, in the example) to start the program which is going to use the tunnel. If no connections are made within the time specified, ssh will exit. X11 FORWARDING If the ForwardX11 variable is set to M-bM-^@M-^\yesM-bM-^@M-^] (or see the description of the -X, -x, and -Y options above) and the user is using X11 (the DISPLAY environment variable is set), the connection to the X11 display is automatically forwarded to the remote side in such a way that any X11 programs started from the shell (or command) will go through the encrypted channel, and the connection to the real X server will be made from the local machine. The user should not manually set DISPLAY. Forwarding of X11 connections can be configured on the command line or in configuration files. The DISPLAY value set by ssh will point to the server machine, but with a display number greater than zero. This is normal, and happens because ssh creates a M-bM-^@M-^\proxyM-bM-^@M-^] X server on the server machine for forwarding the connections over the encrypted channel. ssh will also automatically set up Xauthority data on the server machine. For this purpose, it will generate a random authorization cookie, store it in Xauthority on the server, and verify that any forwarded connections carry this cookie and replace it by the real cookie when the connection is opened. The real authentication cookie is never sent to the server machine (and no cookies are sent in the plain). If the ForwardAgent variable is set to M-bM-^@M-^\yesM-bM-^@M-^] (or see the description of the -A and -a options above) and the user is using an authentication agent, the connection to the agent is automatically forwarded to the remote side. VERIFYING HOST KEYS When connecting to a server for the first time, a fingerprint of the server's public key is presented to the user (unless the option StrictHostKeyChecking has been disabled). Fingerprints can be determined using ssh-keygen(1): $ ssh-keygen -l -f /etc/ssh/ssh_host_rsa_key If the fingerprint is already known, it can be matched and the key can be accepted or rejected. If only legacy (MD5) fingerprints for the server are available, the ssh-keygen(1) -E option may be used to downgrade the fingerprint algorithm to match. Because of the difficulty of comparing host keys just by looking at fingerprint strings, there is also support to compare host keys visually, using random art. By setting the VisualHostKey option to M-bM-^@M-^\yesM-bM-^@M-^], a small ASCII graphic gets displayed on every login to a server, no matter if the session itself is interactive or not. By learning the pattern a known server produces, a user can easily find out that the host key has changed when a completely different pattern is displayed. Because these patterns are not unambiguous however, a pattern that looks similar to the pattern remembered only gives a good probability that the host key is the same, not guaranteed proof. To get a listing of the fingerprints along with their random art for all known hosts, the following command line can be used: $ ssh-keygen -lv -f ~/.ssh/known_hosts If the fingerprint is unknown, an alternative method of verification is available: SSH fingerprints verified by DNS. An additional resource record (RR), SSHFP, is added to a zonefile and the connecting client is able to match the fingerprint with that of the key presented. In this example, we are connecting a client to a server, M-bM-^@M-^\host.example.comM-bM-^@M-^]. The SSHFP resource records should first be added to the zonefile for host.example.com: $ ssh-keygen -r host.example.com. The output lines will have to be added to the zonefile. To check that the zone is answering fingerprint queries: $ dig -t SSHFP host.example.com Finally the client connects: $ ssh -o "VerifyHostKeyDNS ask" host.example.com [...] Matching host key fingerprint found in DNS. Are you sure you want to continue connecting (yes/no)? See the VerifyHostKeyDNS option in ssh_config(5) for more information. SSH-BASED VIRTUAL PRIVATE NETWORKS ssh contains support for Virtual Private Network (VPN) tunnelling using the tun(4) network pseudo-device, allowing two networks to be joined securely. The sshd_config(5) configuration option PermitTunnel controls whether the server supports this, and at what level (layer 2 or 3 traffic). The following example would connect client network 10.0.50.0/24 with remote network 10.0.99.0/24 using a point-to-point connection from 10.1.1.1 to 10.1.1.2, provided that the SSH server running on the gateway to the remote network, at 192.168.1.15, allows it. On the client: # ssh -f -w 0:1 192.168.1.15 true # ifconfig tun0 10.1.1.1 10.1.1.2 netmask 255.255.255.252 # route add 10.0.99.0/24 10.1.1.2 On the server: # ifconfig tun1 10.1.1.2 10.1.1.1 netmask 255.255.255.252 # route add 10.0.50.0/24 10.1.1.1 Client access may be more finely tuned via the /root/.ssh/authorized_keys file (see below) and the PermitRootLogin server option. The following entry would permit connections on tun(4) device 1 from user M-bM-^@M-^\janeM-bM-^@M-^] and on tun device 2 from user M-bM-^@M-^\johnM-bM-^@M-^], if PermitRootLogin is set to M-bM-^@M-^\forced-commands-onlyM-bM-^@M-^]: tunnel="1",command="sh /etc/netstart tun1" ssh-rsa ... jane tunnel="2",command="sh /etc/netstart tun2" ssh-rsa ... john Since an SSH-based setup entails a fair amount of overhead, it may be more suited to temporary setups, such as for wireless VPNs. More permanent VPNs are better provided by tools such as ipsecctl(8) and isakmpd(8). ENVIRONMENT ssh will normally set the following environment variables: DISPLAY The DISPLAY variable indicates the location of the X11 server. It is automatically set by ssh to point to a value of the form M-bM-^@M-^\hostname:nM-bM-^@M-^], where M-bM-^@M-^\hostnameM-bM-^@M-^] indicates the host where the shell runs, and M-bM-^@M-^XnM-bM-^@M-^Y is an integer M-bM-^IM-% 1. ssh uses this special value to forward X11 connections over the secure channel. The user should normally not set DISPLAY explicitly, as that will render the X11 connection insecure (and will require the user to manually copy any required authorization cookies). HOME Set to the path of the user's home directory. LOGNAME Synonym for USER; set for compatibility with systems that use this variable. MAIL Set to the path of the user's mailbox. PATH Set to the default PATH, as specified when compiling ssh. SSH_ASKPASS If ssh needs a passphrase, it will read the passphrase from the current terminal if it was run from a terminal. If ssh does not have a terminal associated with it but DISPLAY and SSH_ASKPASS are set, it will execute the program specified by SSH_ASKPASS and open an X11 window to read the passphrase. This is particularly useful when calling ssh from a .xsession or related script. (Note that on some machines it may be necessary to redirect the input from /dev/null to make this work.) SSH_ASKPASS_REQUIRE Allows further control over the use of an askpass program. If this variable is set to M-bM-^@M-^\neverM-bM-^@M-^] then ssh will never attempt to use one. If it is set to M-bM-^@M-^\preferM-bM-^@M-^], then ssh will prefer to use the askpass program instead of the TTY when requesting passwords. Finally, if the variable is set to M-bM-^@M-^\forceM-bM-^@M-^], then the askpass program will be used for all passphrase input regardless of whether DISPLAY is set. SSH_AUTH_SOCK Identifies the path of a UNIX-domain socket used to communicate with the agent. SSH_CONNECTION Identifies the client and server ends of the connection. The variable contains four space- separated values: client IP address, client port number, server IP address, and server port number. SSH_ORIGINAL_COMMAND This variable contains the original command line if a forced command is executed. It can be used to extract the original arguments. SSH_TTY This is set to the name of the tty (path to the device) associated with the current shell or command. If the current session has no tty, this variable is not set. SSH_TUNNEL Optionally set by sshd(8) to contain the interface names assigned if tunnel forwarding was requested by the client. SSH_USER_AUTH Optionally set by sshd(8), this variable may contain a pathname to a file that lists the authentication methods successfully used when the session was established, including any public keys that were used. TZ This variable is set to indicate the present time zone if it was set when the daemon was started (i.e. the daemon passes the value on to new connections). USER Set to the name of the user logging in. Additionally, ssh reads ~/.ssh/environment, and adds lines of the format M-bM-^@M-^\VARNAME=valueM-bM-^@M-^] to the environment if the file exists and users are allowed to change their environment. For more information, see the PermitUserEnvironment option in sshd_config(5). FILES ~/.rhosts This file is used for host-based authentication (see above). On some machines this file may need to be world-readable if the user's home directory is on an NFS partition, because sshd(8) reads it as root. Additionally, this file must be owned by the user, and must not have write permissions for anyone else. The recommended permission for most machines is read/write for the user, and not accessible by others. ~/.shosts This file is used in exactly the same way as .rhosts, but allows host-based authentication without permitting login with rlogin/rsh. ~/.ssh/ This directory is the default location for all user-specific configuration and authentication information. There is no general requirement to keep the entire contents of this directory secret, but the recommended permissions are read/write/execute for the user, and not accessible by others. ~/.ssh/authorized_keys Lists the public keys (ECDSA, Ed25519, RSA) that can be used for logging in as this user. The format of this file is described in the sshd(8) manual page. This file is not highly sensitive, but the recommended permissions are read/write for the user, and not accessible by others. ~/.ssh/config This is the per-user configuration file. The file format and configuration options are described in ssh_config(5). Because of the potential for abuse, this file must have strict permissions: read/write for the user, and not writable by others. ~/.ssh/environment Contains additional definitions for environment variables; see ENVIRONMENT, above. ~/.ssh/id_ecdsa ~/.ssh/id_ecdsa_sk ~/.ssh/id_ed25519 ~/.ssh/id_ed25519_sk ~/.ssh/id_rsa Contains the private key for authentication. These files contain sensitive data and should be readable by the user but not accessible by others (read/write/execute). ssh will simply ignore a private key file if it is accessible by others. It is possible to specify a passphrase when generating the key which will be used to encrypt the sensitive part of this file using AES-128. ~/.ssh/id_ecdsa.pub ~/.ssh/id_ecdsa_sk.pub ~/.ssh/id_ed25519.pub ~/.ssh/id_ed25519_sk.pub ~/.ssh/id_rsa.pub Contains the public key for authentication. These files are not sensitive and can (but need not) be readable by anyone. ~/.ssh/known_hosts Contains a list of host keys for all hosts the user has logged into that are not already in the systemwide list of known host keys. See sshd(8) for further details of the format of this file. ~/.ssh/rc Commands in this file are executed by ssh when the user logs in, just before the user's shell (or command) is started. See the sshd(8) manual page for more information. /etc/hosts.equiv This file is for host-based authentication (see above). It should only be writable by root. /etc/shosts.equiv This file is used in exactly the same way as hosts.equiv, but allows host-based authentication without permitting login with rlogin/rsh. /etc/ssh/ssh_config Systemwide configuration file. The file format and configuration options are described in ssh_config(5). /etc/ssh/ssh_host_ecdsa_key /etc/ssh/ssh_host_ed25519_key /etc/ssh/ssh_host_rsa_key These files contain the private parts of the host keys and are used for host-based authentication. /etc/ssh/ssh_known_hosts Systemwide list of known host keys. This file should be prepared by the system administrator to contain the public host keys of all machines in the organization. It should be world-readable. See sshd(8) for further details of the format of this file. /etc/ssh/sshrc Commands in this file are executed by ssh when the user logs in, just before the user's shell (or command) is started. See the sshd(8) manual page for more information. EXIT STATUS ssh exits with the exit status of the remote command or with 255 if an error occurred.

The configuration files contain sections separated by Host specifications, and that section is only applied for hosts that match one of the patterns given in the specification. The matched host name is usually the one given on the command line (see the CanonicalizeHostname option for exceptions). Since the first obtained value for each parameter is used, more host- specific declarations should be given near the beginning of the file, and general defaults at the end. The file contains keyword-argument pairs, one per line. Lines starting with M-bM-^@M-^X#M-bM-^@M-^Y and empty lines are interpreted as comments. Arguments may optionally be enclosed in double quotes (") in order to represent arguments containing spaces. Configuration options may be separated by whitespace or optional whitespace and exactly one M-bM-^@M-^X=M-bM-^@M-^Y; the latter format is useful to avoid the need to quote whitespace when specifying configuration options using the ssh, scp, and sftp -o option. The possible keywords and their meanings are as follows (note that keywords are case-insensitive and arguments are case-sensitive): Host Restricts the following declarations (up to the next Host or Match keyword) to be only for those hosts that match one of the patterns given after the keyword. If more than one pattern is provided, they should be separated by whitespace. A single M-bM-^@M-^X*M-bM-^@M-^Y as a pattern can be used to provide global defaults for all hosts. The host is usually the hostname argument given on the command line (see the CanonicalizeHostname keyword for exceptions). A pattern entry may be negated by prefixing it with an exclamation mark (M-bM-^@M-^X!M-bM-^@M-^Y). If a negated entry is matched, then the Host entry is ignored, regardless of whether any other patterns on the line match. Negated matches are therefore useful to provide exceptions for wildcard matches. See PATTERNS for more information on patterns. Match Restricts the following declarations (up to the next Host or Match keyword) to be used only when the conditions following the Match keyword are satisfied. Match conditions are specified using one or more criteria or the single token all which always matches. The available criteria keywords are: canonical, final, exec, localnetwork, host, originalhost, tagged, user, and localuser. The all criteria must appear alone or immediately after canonical or final. Other criteria may be combined arbitrarily. All criteria but all, canonical, and final require an argument. Criteria may be negated by prepending an exclamation mark (M-bM-^@M-^X!M-bM-^@M-^Y). The canonical keyword matches only when the configuration file is being re-parsed after hostname canonicalization (see the CanonicalizeHostname option). This may be useful to specify conditions that work with canonical host names only. The final keyword requests that the configuration be re-parsed (regardless of whether CanonicalizeHostname is enabled), and matches only during this final pass. If CanonicalizeHostname is enabled, then canonical and final match during the same pass. The exec keyword executes the specified command under the user's shell. If the command returns a zero exit status then the condition is considered true. Commands containing whitespace characters must be quoted. Arguments to exec accept the tokens described in the TOKENS section. The localnetwork keyword matches the addresses of active local network interfaces against the supplied list of networks in CIDR format. This may be convenient for varying the effective configuration on devices that roam between networks. Note that network address is not a trustworthy criteria in many situations (e.g. when the network is automatically configured using DHCP) and so caution should be applied if using it to control security- sensitive configuration. The other keywords' criteria must be single entries or comma- separated lists and may use the wildcard and negation operators described in the PATTERNS section. The criteria for the host keyword are matched against the target hostname, after any substitution by the Hostname or CanonicalizeHostname options. The originalhost keyword matches against the hostname as it was specified on the command-line. The tagged keyword matches a tag name specified by a prior Tag directive or on the ssh(1) command- line using the -P flag. The user keyword matches against the target username on the remote host. The localuser keyword matches against the name of the local user running ssh(1) (this keyword may be useful in system-wide ssh_config files). AddKeysToAgent Specifies whether keys should be automatically added to a running ssh-agent(1). If this option is set to yes and a key is loaded from a file, the key and its passphrase are added to the agent with the default lifetime, as if by ssh-add(1). If this option is set to ask, ssh(1) will require confirmation using the SSH_ASKPASS program before adding a key (see ssh-add(1) for details). If this option is set to confirm, each use of the key must be confirmed, as if the -c option was specified to ssh-add(1). If this option is set to no, no keys are added to the agent. Alternately, this option may be specified as a time interval using the format described in the TIME FORMATS section of sshd_config(5) to specify the key's lifetime in ssh-agent(1), after which it will automatically be removed. The argument must be no (the default), yes, confirm (optionally followed by a time interval), ask or a time interval. AddressFamily Specifies which address family to use when connecting. Valid arguments are any (the default), inet (use IPv4 only), or inet6 (use IPv6 only). BatchMode If set to yes, user interaction such as password prompts and host key confirmation requests will be disabled. This option is useful in scripts and other batch jobs where no user is present to interact with ssh(1). The argument must be yes or no (the default). BindAddress Use the specified address on the local machine as the source address of the connection. Only useful on systems with more than one address. BindInterface Use the address of the specified interface on the local machine as the source address of the connection. CanonicalDomains When CanonicalizeHostname is enabled, this option specifies the list of domain suffixes in which to search for the specified destination host. CanonicalizeFallbackLocal Specifies whether to fail with an error when hostname canonicalization fails. The default, yes, will attempt to look up the unqualified hostname using the system resolver's search rules. A value of no will cause ssh(1) to fail instantly if CanonicalizeHostname is enabled and the target hostname cannot be found in any of the domains specified by CanonicalDomains. CanonicalizeHostname Controls whether explicit hostname canonicalization is performed. The default, no, is not to perform any name rewriting and let the system resolver handle all hostname lookups. If set to yes then, for connections that do not use a ProxyCommand or ProxyJump, ssh(1) will attempt to canonicalize the hostname specified on the command line using the CanonicalDomains suffixes and CanonicalizePermittedCNAMEs rules. If CanonicalizeHostname is set to always, then canonicalization is applied to proxied connections too. If this option is enabled, then the configuration files are processed again using the new target name to pick up any new configuration in matching Host and Match stanzas. A value of none disables the use of a ProxyJump host. CanonicalizeMaxDots Specifies the maximum number of dot characters in a hostname before canonicalization is disabled. The default, 1, allows a single dot (i.e. hostname.subdomain). CanonicalizePermittedCNAMEs Specifies rules to determine whether CNAMEs should be followed when canonicalizing hostnames. The rules consist of one or more arguments of source_domain_list:target_domain_list, where source_domain_list is a pattern-list of domains that may follow CNAMEs in canonicalization, and target_domain_list is a pattern- list of domains that they may resolve to. For example, "*.a.example.com:*.b.example.com,*.c.example.com" will allow hostnames matching "*.a.example.com" to be canonicalized to names in the "*.b.example.com" or "*.c.example.com" domains. A single argument of "none" causes no CNAMEs to be considered for canonicalization. This is the default behaviour. CASignatureAlgorithms Specifies which algorithms are allowed for signing of certificates by certificate authorities (CAs). The default is: ssh-ed25519,ecdsa-sha2-nistp256, ecdsa-sha2-nistp384,ecdsa-sha2-nistp521, sk-ssh-ed25519@openssh.com, sk-ecdsa-sha2-nistp256@openssh.com, rsa-sha2-512,rsa-sha2-256 If the specified list begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified algorithms will be appended to the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified algorithms (including wildcards) will be removed from the default set instead of replacing them. ssh(1) will not accept host certificates signed using algorithms other than those specified. CertificateFile Specifies a file from which the user's certificate is read. A corresponding private key must be provided separately in order to use this certificate either from an IdentityFile directive or -i flag to ssh(1), via ssh-agent(1), or via a PKCS11Provider or SecurityKeyProvider. Arguments to CertificateFile may use the tilde syntax to refer to a user's home directory, the tokens described in the TOKENS section and environment variables as described in the ENVIRONMENT VARIABLES section. It is possible to have multiple certificate files specified in configuration files; these certificates will be tried in sequence. Multiple CertificateFile directives will add to the list of certificates used for authentication. ChannelTimeout Specifies whether and how quickly ssh(1) should close inactive channels. Timeouts are specified as one or more M-bM-^@M-^\type=intervalM-bM-^@M-^] pairs separated by whitespace, where the M-bM-^@M-^\typeM-bM-^@M-^] must be the special keyword M-bM-^@M-^\globalM-bM-^@M-^] or a channel type name from the list below, optionally containing wildcard characters. The timeout value M-bM-^@M-^\intervalM-bM-^@M-^] is specified in seconds or may use any of the units documented in the TIME FORMATS section. For example, M-bM-^@M-^\session=5mM-bM-^@M-^] would cause interactive sessions to terminate after five minutes of inactivity. Specifying a zero value disables the inactivity timeout. The special timeout M-bM-^@M-^\globalM-bM-^@M-^] applies to all active channels, taken together. Traffic on any active channel will reset the timeout, but when the timeout expires then all open channels will be closed. Note that this global timeout is not matched by wildcards and must be specified explicitly. The available channel type names include: agent-connection Open connections to ssh-agent(1). direct-tcpip, direct-streamlocal@openssh.com Open TCP or Unix socket (respectively) connections that have been established from a ssh(1) local forwarding, i.e. LocalForward or DynamicForward. forwarded-tcpip, forwarded-streamlocal@openssh.com Open TCP or Unix socket (respectively) connections that have been established to a sshd(8) listening on behalf of a ssh(1) remote forwarding, i.e. RemoteForward. session The interactive main session, including shell session, command execution, scp(1), sftp(1), etc. tun-connection Open TunnelForward connections. x11-connection Open X11 forwarding sessions. Note that in all the above cases, terminating an inactive session does not guarantee to remove all resources associated with the session, e.g. shell processes or X11 clients relating to the session may continue to execute. Moreover, terminating an inactive channel or session does not necessarily close the SSH connection, nor does it prevent a client from requesting another channel of the same type. In particular, expiring an inactive forwarding session does not prevent another identical forwarding from being subsequently created. The default is not to expire channels of any type for inactivity. CheckHostIP If set to yes, ssh(1) will additionally check the host IP address in the known_hosts file. This allows it to detect if a host key changed due to DNS spoofing and will add addresses of destination hosts to ~/.ssh/known_hosts in the process, regardless of the setting of StrictHostKeyChecking. If the option is set to no (the default), the check will not be executed. Ciphers Specifies the ciphers allowed and their order of preference. Multiple ciphers must be comma-separated. If the specified list begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified ciphers will be appended to the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified ciphers (including wildcards) will be removed from the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X^M-bM-^@M-^Y character, then the specified ciphers will be placed at the head of the default set. The supported ciphers are: 3des-cbc aes128-cbc aes192-cbc aes256-cbc aes128-ctr aes192-ctr aes256-ctr aes128-gcm@openssh.com aes256-gcm@openssh.com chacha20-poly1305@openssh.com The default is: chacha20-poly1305@openssh.com, aes128-ctr,aes192-ctr,aes256-ctr, aes128-gcm@openssh.com,aes256-gcm@openssh.com The list of available ciphers may also be obtained using "ssh -Q cipher". ClearAllForwardings Specifies that all local, remote, and dynamic port forwardings specified in the configuration files or on the command line be cleared. This option is primarily useful when used from the ssh(1) command line to clear port forwardings set in configuration files, and is automatically set by scp(1) and sftp(1). The argument must be yes or no (the default). Compression Specifies whether to use compression. The argument must be yes or no (the default). ConnectionAttempts Specifies the number of tries (one per second) to make before exiting. The argument must be an integer. This may be useful in scripts if the connection sometimes fails. The default is 1. ConnectTimeout Specifies the timeout (in seconds) used when connecting to the SSH server, instead of using the default system TCP timeout. This timeout is applied both to establishing the connection and to performing the initial SSH protocol handshake and key exchange. ControlMaster Enables the sharing of multiple sessions over a single network connection. When set to yes, ssh(1) will listen for connections on a control socket specified using the ControlPath argument. Additional sessions can connect to this socket using the same ControlPath with ControlMaster set to no (the default). These sessions will try to reuse the master instance's network connection rather than initiating new ones, but will fall back to connecting normally if the control socket does not exist, or is not listening. Setting this to ask will cause ssh(1) to listen for control connections, but require confirmation using ssh-askpass(1). If the ControlPath cannot be opened, ssh(1) will continue without connecting to a master instance. X11 and ssh-agent(1) forwarding is supported over these multiplexed connections, however the display and agent forwarded will be the one belonging to the master connection i.e. it is not possible to forward multiple displays or agents. Two additional options allow for opportunistic multiplexing: try to use a master connection but fall back to creating a new one if one does not already exist. These options are: auto and autoask. The latter requires confirmation like the ask option. ControlPath Specify the path to the control socket used for connection sharing as described in the ControlMaster section above or the string none to disable connection sharing. Arguments to ControlPath may use the tilde syntax to refer to a user's home directory, the tokens described in the TOKENS section and environment variables as described in the ENVIRONMENT VARIABLES section. It is recommended that any ControlPath used for opportunistic connection sharing include at least %h, %p, and %r (or alternatively %C) and be placed in a directory that is not writable by other users. This ensures that shared connections are uniquely identified. ControlPersist When used in conjunction with ControlMaster, specifies that the master connection should remain open in the background (waiting for future client connections) after the initial client connection has been closed. If set to no (the default), then the master connection will not be placed into the background, and will close as soon as the initial client connection is closed. If set to yes or 0, then the master connection will remain in the background indefinitely (until killed or closed via a mechanism such as the "ssh -O exit"). If set to a time in seconds, or a time in any of the formats documented in sshd_config(5), then the backgrounded master connection will automatically terminate after it has remained idle (with no client connections) for the specified time. DynamicForward Specifies that a TCP port on the local machine be forwarded over the secure channel, and the application protocol is then used to determine where to connect to from the remote machine. The argument must be [bind_address:]port. IPv6 addresses can be specified by enclosing addresses in square brackets. By default, the local port is bound in accordance with the GatewayPorts setting. However, an explicit bind_address may be used to bind the connection to a specific address. The bind_address of localhost indicates that the listening port be bound for local use only, while an empty address or M-bM-^@M-^X*M-bM-^@M-^Y indicates that the port should be available from all interfaces. Currently the SOCKS4 and SOCKS5 protocols are supported, and ssh(1) will act as a SOCKS server. Multiple forwardings may be specified, and additional forwardings can be given on the command line. Only the superuser can forward privileged ports. EnableEscapeCommandline Enables the command line option in the EscapeChar menu for interactive sessions (default M-bM-^@M-^X~CM-bM-^@M-^Y). By default, the command line is disabled. EnableSSHKeysign Setting this option to yes in the global client configuration file /etc/ssh/ssh_config enables the use of the helper program ssh-keysign(8) during HostbasedAuthentication. The argument must be yes or no (the default). This option should be placed in the non-hostspecific section. See ssh-keysign(8) for more information. EscapeChar Sets the escape character (default: M-bM-^@M-^X~M-bM-^@M-^Y). The escape character can also be set on the command line. The argument should be a single character, M-bM-^@M-^X^M-bM-^@M-^Y followed by a letter, or none to disable the escape character entirely (making the connection transparent for binary data). ExitOnForwardFailure Specifies whether ssh(1) should terminate the connection if it cannot set up all requested dynamic, tunnel, local, and remote port forwardings, (e.g. if either end is unable to bind and listen on a specified port). Note that ExitOnForwardFailure does not apply to connections made over port forwardings and will not, for example, cause ssh(1) to exit if TCP connections to the ultimate forwarding destination fail. The argument must be yes or no (the default). FingerprintHash Specifies the hash algorithm used when displaying key fingerprints. Valid options are: md5 and sha256 (the default). ForkAfterAuthentication Requests ssh to go to background just before command execution. This is useful if ssh is going to ask for passwords or passphrases, but the user wants it in the background. This implies the StdinNull configuration option being set to M-bM-^@M-^\yesM-bM-^@M-^]. The recommended way to start X11 programs at a remote site is with something like ssh -f host xterm, which is the same as ssh host xterm if the ForkAfterAuthentication configuration option is set to M-bM-^@M-^\yesM-bM-^@M-^]. If the ExitOnForwardFailure configuration option is set to M-bM-^@M-^\yesM-bM-^@M-^], then a client started with the ForkAfterAuthentication configuration option being set to M-bM-^@M-^\yesM-bM-^@M-^] will wait for all remote port forwards to be successfully established before placing itself in the background. The argument to this keyword must be yes (same as the -f option) or no (the default). ForwardAgent Specifies whether the connection to the authentication agent (if any) will be forwarded to the remote machine. The argument may be yes, no (the default), an explicit path to an agent socket or the name of an environment variable (beginning with M-bM-^@M-^X$M-bM-^@M-^Y) in which to find the path. Agent forwarding should be enabled with caution. Users with the ability to bypass file permissions on the remote host (for the agent's Unix-domain socket) can access the local agent through the forwarded connection. An attacker cannot obtain key material from the agent, however they can perform operations on the keys that enable them to authenticate using the identities loaded into the agent. ForwardX11 Specifies whether X11 connections will be automatically redirected over the secure channel and DISPLAY set. The argument must be yes or no (the default). X11 forwarding should be enabled with caution. Users with the ability to bypass file permissions on the remote host (for the user's X11 authorization database) can access the local X11 display through the forwarded connection. An attacker may then be able to perform activities such as keystroke monitoring if the ForwardX11Trusted option is also enabled. ForwardX11Timeout Specify a timeout for untrusted X11 forwarding using the format described in the TIME FORMATS section of sshd_config(5). X11 connections received by ssh(1) after this time will be refused. Setting ForwardX11Timeout to zero will disable the timeout and permit X11 forwarding for the life of the connection. The default is to disable untrusted X11 forwarding after twenty minutes has elapsed. ForwardX11Trusted If this option is set to yes, remote X11 clients will have full access to the original X11 display. If this option is set to no (the default), remote X11 clients will be considered untrusted and prevented from stealing or tampering with data belonging to trusted X11 clients. Furthermore, the xauth(1) token used for the session will be set to expire after 20 minutes. Remote clients will be refused access after this time. See the X11 SECURITY extension specification for full details on the restrictions imposed on untrusted clients. GatewayPorts Specifies whether remote hosts are allowed to connect to local forwarded ports. By default, ssh(1) binds local port forwardings to the loopback address. This prevents other remote hosts from connecting to forwarded ports. GatewayPorts can be used to specify that ssh should bind local port forwardings to the wildcard address, thus allowing remote hosts to connect to forwarded ports. The argument must be yes or no (the default). GlobalKnownHostsFile Specifies one or more files to use for the global host key database, separated by whitespace. The default is /etc/ssh/ssh_known_hosts, /etc/ssh/ssh_known_hosts2. GSSAPIAuthentication Specifies whether user authentication based on GSSAPI is allowed. The default is no. GSSAPIDelegateCredentials Forward (delegate) credentials to the server. The default is no. HashKnownHosts Indicates that ssh(1) should hash host names and addresses when they are added to ~/.ssh/known_hosts. These hashed names may be used normally by ssh(1) and sshd(8), but they do not visually reveal identifying information if the file's contents are disclosed. The default is no. Note that existing names and addresses in known hosts files will not be converted automatically, but may be manually hashed using ssh-keygen(1). HostbasedAcceptedAlgorithms Specifies the signature algorithms that will be used for hostbased authentication as a comma-separated list of patterns. Alternately if the specified list begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified signature algorithms will be appended to the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified signature algorithms (including wildcards) will be removed from the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X^M-bM-^@M-^Y character, then the specified signature algorithms will be placed at the head of the default set. The default for this option is: ssh-ed25519-cert-v01@openssh.com, ecdsa-sha2-nistp256-cert-v01@openssh.com, ecdsa-sha2-nistp384-cert-v01@openssh.com, ecdsa-sha2-nistp521-cert-v01@openssh.com, sk-ssh-ed25519-cert-v01@openssh.com, sk-ecdsa-sha2-nistp256-cert-v01@openssh.com, rsa-sha2-512-cert-v01@openssh.com, rsa-sha2-256-cert-v01@openssh.com, ssh-ed25519, ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521, sk-ssh-ed25519@openssh.com, sk-ecdsa-sha2-nistp256@openssh.com, rsa-sha2-512,rsa-sha2-256 The -Q option of ssh(1) may be used to list supported signature algorithms. This was formerly named HostbasedKeyTypes. HostbasedAuthentication Specifies whether to try rhosts based authentication with public key authentication. The argument must be yes or no (the default). HostKeyAlgorithms Specifies the host key signature algorithms that the client wants to use in order of preference. Alternately if the specified list begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified signature algorithms will be appended to the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified signature algorithms (including wildcards) will be removed from the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X^M-bM-^@M-^Y character, then the specified signature algorithms will be placed at the head of the default set. The default for this option is: ssh-ed25519-cert-v01@openssh.com, ecdsa-sha2-nistp256-cert-v01@openssh.com, ecdsa-sha2-nistp384-cert-v01@openssh.com, ecdsa-sha2-nistp521-cert-v01@openssh.com, sk-ssh-ed25519-cert-v01@openssh.com, sk-ecdsa-sha2-nistp256-cert-v01@openssh.com, rsa-sha2-512-cert-v01@openssh.com, rsa-sha2-256-cert-v01@openssh.com, ssh-ed25519, ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521, sk-ecdsa-sha2-nistp256@openssh.com, sk-ssh-ed25519@openssh.com, rsa-sha2-512,rsa-sha2-256 If hostkeys are known for the destination host then this default is modified to prefer their algorithms. The list of available signature algorithms may also be obtained using "ssh -Q HostKeyAlgorithms". HostKeyAlias Specifies an alias that should be used instead of the real host name when looking up or saving the host key in the host key database files and when validating host certificates. This option is useful for tunneling SSH connections or for multiple servers running on a single host. Hostname Specifies the real host name to log into. This can be used to specify nicknames or abbreviations for hosts. Arguments to Hostname accept the tokens described in the TOKENS section. Numeric IP addresses are also permitted (both on the command line and in Hostname specifications). The default is the name given on the command line. IdentitiesOnly Specifies that ssh(1) should only use the configured authentication identity and certificate files (either the default files, or those explicitly configured in the ssh_config files or passed on the ssh(1) command-line), even if ssh-agent(1) or a PKCS11Provider or SecurityKeyProvider offers more identities. The argument to this keyword must be yes or no (the default). This option is intended for situations where ssh-agent offers many different identities. IdentityAgent Specifies the UNIX-domain socket used to communicate with the authentication agent. This option overrides the SSH_AUTH_SOCK environment variable and can be used to select a specific agent. Setting the socket name to none disables the use of an authentication agent. If the string "SSH_AUTH_SOCK" is specified, the location of the socket will be read from the SSH_AUTH_SOCK environment variable. Otherwise if the specified value begins with a M-bM-^@M-^X$M-bM-^@M-^Y character, then it will be treated as an environment variable containing the location of the socket. Arguments to IdentityAgent may use the tilde syntax to refer to a user's home directory, the tokens described in the TOKENS section and environment variables as described in the ENVIRONMENT VARIABLES section. IdentityFile Specifies a file from which the user's ECDSA, authenticator- hosted ECDSA, Ed25519, authenticator-hosted Ed25519 or RSA authentication identity is read. You can also specify a public key file to use the corresponding private key that is loaded in ssh-agent(1) when the private key file is not present locally. The default is ~/.ssh/id_rsa, ~/.ssh/id_ecdsa, ~/.ssh/id_ecdsa_sk, ~/.ssh/id_ed25519 and ~/.ssh/id_ed25519_sk. Additionally, any identities represented by the authentication agent will be used for authentication unless IdentitiesOnly is set. If no certificates have been explicitly specified by CertificateFile, ssh(1) will try to load certificate information from the filename obtained by appending -cert.pub to the path of a specified IdentityFile. Arguments to IdentityFile may use the tilde syntax to refer to a user's home directory or the tokens described in the TOKENS section. Alternately an argument of none may be used to indicate no identity files should be loaded. It is possible to have multiple identity files specified in configuration files; all these identities will be tried in sequence. Multiple IdentityFile directives will add to the list of identities tried (this behaviour differs from that of other configuration directives). IdentityFile may be used in conjunction with IdentitiesOnly to select which identities in an agent are offered during authentication. IdentityFile may also be used in conjunction with CertificateFile in order to provide any certificate also needed for authentication with the identity. IgnoreUnknown Specifies a pattern-list of unknown options to be ignored if they are encountered in configuration parsing. This may be used to suppress errors if ssh_config contains options that are unrecognised by ssh(1). It is recommended that IgnoreUnknown be listed early in the configuration file as it will not be applied to unknown options that appear before it. Include Include the specified configuration file(s). Multiple pathnames may be specified and each pathname may contain glob(7) wildcards, tokens as described in the TOKENS section, environment variables as described in the ENVIRONMENT VARIABLES section and, for user configurations, shell-like M-bM-^@M-^X~M-bM-^@M-^Y references to user home directories. Wildcards will be expanded and processed in lexical order. Files without absolute paths are assumed to be in ~/.ssh if included in a user configuration file or /etc/ssh if included from the system configuration file. Include directive may appear inside a Match or Host block to perform conditional inclusion. IPQoS Specifies the IPv4 type-of-service or DSCP class for connections. Accepted values are af11, af12, af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, cs0, cs1, cs2, cs3, cs4, cs5, cs6, cs7, ef, le, lowdelay, throughput, reliability, a numeric value, or none to use the operating system default. This option may take one or two arguments, separated by whitespace. If one argument is specified, it is used as the packet class unconditionally. If two values are specified, the first is automatically selected for interactive sessions and the second for non-interactive sessions. The default is af21 (Low-Latency Data) for interactive sessions and cs1 (Lower Effort) for non- interactive sessions. KbdInteractiveAuthentication Specifies whether to use keyboard-interactive authentication. The argument to this keyword must be yes (the default) or no. ChallengeResponseAuthentication is a deprecated alias for this. KbdInteractiveDevices Specifies the list of methods to use in keyboard-interactive authentication. Multiple method names must be comma-separated. The default is to use the server specified list. The methods available vary depending on what the server supports. For an OpenSSH server, it may be zero or more of: bsdauth and pam. KexAlgorithms Specifies the permitted KEX (Key Exchange) algorithms that will be used and their preference order. The selected algorithm will be the first algorithm in this list that the server also supports. Multiple algorithms must be comma-separated. If the specified list begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified algorithms will be appended to the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified algorithms (including wildcards) will be removed from the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X^M-bM-^@M-^Y character, then the specified algorithms will be placed at the head of the default set. The default is: sntrup761x25519-sha512,sntrup761x25519-sha512@openssh.com, mlkem768x25519-sha256, curve25519-sha256,curve25519-sha256@libssh.org, ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521, diffie-hellman-group-exchange-sha256, diffie-hellman-group16-sha512, diffie-hellman-group18-sha512, diffie-hellman-group14-sha256 The list of supported key exchange algorithms may also be obtained using "ssh -Q kex". KnownHostsCommand Specifies a command to use to obtain a list of host keys, in addition to those listed in UserKnownHostsFile and GlobalKnownHostsFile. This command is executed after the files have been read. It may write host key lines to standard output in identical format to the usual files (described in the VERIFYING HOST KEYS section in ssh(1)). Arguments to KnownHostsCommand accept the tokens described in the TOKENS section. The command may be invoked multiple times per connection: once when preparing the preference list of host key algorithms to use, again to obtain the host key for the requested host name and, if CheckHostIP is enabled, one more time to obtain the host key matching the server's address. If the command exits abnormally or returns a non-zero exit status then the connection is terminated. LocalCommand Specifies a command to execute on the local machine after successfully connecting to the server. The command string extends to the end of the line, and is executed with the user's shell. Arguments to LocalCommand accept the tokens described in the TOKENS section. The command is run synchronously and does not have access to the session of the ssh(1) that spawned it. It should not be used for interactive commands. This directive is ignored unless PermitLocalCommand has been enabled. LocalForward Specifies that a TCP port on the local machine be forwarded over the secure channel to the specified host and port from the remote machine. The first argument specifies the listener and may be [bind_address:]port or a Unix domain socket path. The second argument is the destination and may be host:hostport or a Unix domain socket path if the remote host supports it. IPv6 addresses can be specified by enclosing addresses in square brackets. Multiple forwardings may be specified, and additional forwardings can be given on the command line. Only the superuser can forward privileged ports. By default, the local port is bound in accordance with the GatewayPorts setting. However, an explicit bind_address may be used to bind the connection to a specific address. The bind_address of localhost indicates that the listening port be bound for local use only, while an empty address or M-bM-^@M-^X*M-bM-^@M-^Y indicates that the port should be available from all interfaces. Unix domain socket paths may use the tokens described in the TOKENS section and environment variables as described in the ENVIRONMENT VARIABLES section. LogLevel Gives the verbosity level that is used when logging messages from ssh(1). The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2, and DEBUG3. The default is INFO. DEBUG and DEBUG1 are equivalent. DEBUG2 and DEBUG3 each specify higher levels of verbose output. LogVerbose Specify one or more overrides to LogLevel. An override consists of one or more pattern lists that matches the source file, function and line number to force detailed logging for. For example, an override pattern of: kex.c:*:1000,*:kex_exchange_identification():*,packet.c:* would enable detailed logging for line 1000 of kex.c, everything in the kex_exchange_identification() function, and all code in the packet.c file. This option is intended for debugging and no overrides are enabled by default. MACs Specifies the MAC (message authentication code) algorithms in order of preference. The MAC algorithm is used for data integrity protection. Multiple algorithms must be comma- separated. If the specified list begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified algorithms will be appended to the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified algorithms (including wildcards) will be removed from the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X^M-bM-^@M-^Y character, then the specified algorithms will be placed at the head of the default set. The algorithms that contain "-etm" calculate the MAC after encryption (encrypt-then-mac). These are considered safer and their use recommended. The default is: umac-64-etm@openssh.com,umac-128-etm@openssh.com, hmac-sha2-256-etm@openssh.com,hmac-sha2-512-etm@openssh.com, hmac-sha1-etm@openssh.com, umac-64@openssh.com,umac-128@openssh.com, hmac-sha2-256,hmac-sha2-512,hmac-sha1 The list of available MAC algorithms may also be obtained using "ssh -Q mac". NoHostAuthenticationForLocalhost Disable host authentication for localhost (loopback addresses). The argument to this keyword must be yes or no (the default). NumberOfPasswordPrompts Specifies the number of password prompts before giving up. The argument to this keyword must be an integer. The default is 3. ObscureKeystrokeTiming Specifies whether ssh(1) should try to obscure inter-keystroke timings from passive observers of network traffic. If enabled, then for interactive sessions, ssh(1) will send keystrokes at fixed intervals of a few tens of milliseconds and will send fake keystroke packets for some time after typing ceases. The argument to this keyword must be yes, no or an interval specifier of the form interval:milliseconds (e.g. interval:80 for 80 milliseconds). The default is to obscure keystrokes using a 20ms packet interval. Note that smaller intervals will result in higher fake keystroke packet rates. PasswordAuthentication Specifies whether to use password authentication. The argument to this keyword must be yes (the default) or no. PermitLocalCommand Allow local command execution via the LocalCommand option or using the !command escape sequence in ssh(1). The argument must be yes or no (the default). PermitRemoteOpen Specifies the destinations to which remote TCP port forwarding is permitted when RemoteForward is used as a SOCKS proxy. The forwarding specification must be one of the following forms: PermitRemoteOpen host:port PermitRemoteOpen IPv4_addr:port PermitRemoteOpen [IPv6_addr]:port Multiple forwards may be specified by separating them with whitespace. An argument of any can be used to remove all restrictions and permit any forwarding requests. An argument of none can be used to prohibit all forwarding requests. The wildcard M-bM-^@M-^X*M-bM-^@M-^Y can be used for host or port to allow all hosts or ports respectively. Otherwise, no pattern matching or address lookups are performed on supplied names. PKCS11Provider Specifies which PKCS#11 provider to use or none to indicate that no provider should be used (the default). The argument to this keyword is a path to the PKCS#11 shared library ssh(1) should use to communicate with a PKCS#11 token providing keys for user authentication. Port Specifies the port number to connect on the remote host. The default is 22. PreferredAuthentications Specifies the order in which the client should try authentication methods. This allows a client to prefer one method (e.g. keyboard-interactive) over another method (e.g. password). The default is: gssapi-with-mic,hostbased,publickey, keyboard-interactive,password ProxyCommand Specifies the command to use to connect to the server. The command string extends to the end of the line, and is executed using the user's shell M-bM-^@M-^XexecM-bM-^@M-^Y directive to avoid a lingering shell process. Arguments to ProxyCommand accept the tokens described in the TOKENS section. The command can be basically anything, and should read from its standard input and write to its standard output. It should eventually connect an sshd(8) server running on some machine, or execute sshd -i somewhere. Host key management will be done using the Hostname of the host being connected (defaulting to the name typed by the user). Setting the command to none disables this option entirely. Note that CheckHostIP is not available for connects with a proxy command. This directive is useful in conjunction with nc(1) and its proxy support. For example, the following directive would connect via an HTTP proxy at 192.0.2.0: ProxyCommand /usr/bin/nc -X connect -x 192.0.2.0:8080 %h %p ProxyJump Specifies one or more jump proxies as either [user@]host[:port] or an ssh URI. Multiple proxies may be separated by comma characters and will be visited sequentially. Setting this option will cause ssh(1) to connect to the target host by first making a ssh(1) connection to the specified ProxyJump host and then establishing a TCP forwarding to the ultimate target from there. Setting the host to none disables this option entirely. Note that this option will compete with the ProxyCommand option - whichever is specified first will prevent later instances of the other from taking effect. Note also that the configuration for the destination host (either supplied via the command-line or the configuration file) is not generally applied to jump hosts. ~/.ssh/config should be used if specific configuration is required for jump hosts. ProxyUseFdpass Specifies that ProxyCommand will pass a connected file descriptor back to ssh(1) instead of continuing to execute and pass data. The default is no. PubkeyAcceptedAlgorithms Specifies the signature algorithms that will be used for public key authentication as a comma-separated list of patterns. If the specified list begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the algorithms after it will be appended to the default instead of replacing it. If the specified list begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified algorithms (including wildcards) will be removed from the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X^M-bM-^@M-^Y character, then the specified algorithms will be placed at the head of the default set. The default for this option is: ssh-ed25519-cert-v01@openssh.com, ecdsa-sha2-nistp256-cert-v01@openssh.com, ecdsa-sha2-nistp384-cert-v01@openssh.com, ecdsa-sha2-nistp521-cert-v01@openssh.com, sk-ssh-ed25519-cert-v01@openssh.com, sk-ecdsa-sha2-nistp256-cert-v01@openssh.com, rsa-sha2-512-cert-v01@openssh.com, rsa-sha2-256-cert-v01@openssh.com, ssh-ed25519, ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521, sk-ssh-ed25519@openssh.com, sk-ecdsa-sha2-nistp256@openssh.com, rsa-sha2-512,rsa-sha2-256 The list of available signature algorithms may also be obtained using "ssh -Q PubkeyAcceptedAlgorithms". PubkeyAuthentication Specifies whether to try public key authentication. The argument to this keyword must be yes (the default), no, unbound or host-bound. The final two options enable public key authentication while respectively disabling or enabling the OpenSSH host-bound authentication protocol extension required for restricted ssh-agent(1) forwarding. RekeyLimit Specifies the maximum amount of data that may be transmitted or received before the session key is renegotiated, optionally followed by a maximum amount of time that may pass before the session key is renegotiated. The first argument is specified in bytes and may have a suffix of M-bM-^@M-^XKM-bM-^@M-^Y, M-bM-^@M-^XMM-bM-^@M-^Y, or M-bM-^@M-^XGM-bM-^@M-^Y to indicate Kilobytes, Megabytes, or Gigabytes, respectively. The default is between M-bM-^@M-^X1GM-bM-^@M-^Y and M-bM-^@M-^X4GM-bM-^@M-^Y, depending on the cipher. The optional second value is specified in seconds and may use any of the units documented in the TIME FORMATS section of sshd_config(5). The default value for RekeyLimit is default none, which means that rekeying is performed after the cipher's default amount of data has been sent or received and no time based rekeying is done. RemoteCommand Specifies a command to execute on the remote machine after successfully connecting to the server. The command string extends to the end of the line, and is executed with the user's shell. Arguments to RemoteCommand accept the tokens described in the TOKENS section. RemoteForward Specifies that a TCP port on the remote machine be forwarded over the secure channel. The remote port may either be forwarded to a specified host and port from the local machine, or may act as a SOCKS 4/5 proxy that allows a remote client to connect to arbitrary destinations from the local machine. The first argument is the listening specification and may be [bind_address:]port or, if the remote host supports it, a Unix domain socket path. If forwarding to a specific destination then the second argument must be host:hostport or a Unix domain socket path, otherwise if no destination argument is specified then the remote forwarding will be established as a SOCKS proxy. When acting as a SOCKS proxy, the destination of the connection can be restricted by PermitRemoteOpen. IPv6 addresses can be specified by enclosing addresses in square brackets. Multiple forwardings may be specified, and additional forwardings can be given on the command line. Privileged ports can be forwarded only when logging in as root on the remote machine. Unix domain socket paths may use the tokens described in the TOKENS section and environment variables as described in the ENVIRONMENT VARIABLES section. If the port argument is 0, the listen port will be dynamically allocated on the server and reported to the client at run time. If the bind_address is not specified, the default is to only bind to loopback addresses. If the bind_address is M-bM-^@M-^X*M-bM-^@M-^Y or an empty string, then the forwarding is requested to listen on all interfaces. Specifying a remote bind_address will only succeed if the server's GatewayPorts option is enabled (see sshd_config(5)). RequestTTY Specifies whether to request a pseudo-tty for the session. The argument may be one of: no (never request a TTY), yes (always request a TTY when standard input is a TTY), force (always request a TTY) or auto (request a TTY when opening a login session). This option mirrors the -t and -T flags for ssh(1). RequiredRSASize Specifies the minimum RSA key size (in bits) that ssh(1) will accept. User authentication keys smaller than this limit will be ignored. Servers that present host keys smaller than this limit will cause the connection to be terminated. The default is 1024 bits. Note that this limit may only be raised from the default. RevokedHostKeys Specifies revoked host public keys. Keys listed in this file will be refused for host authentication. Note that if this file does not exist or is not readable, then host authentication will be refused for all hosts. Keys may be specified as a text file, listing one public key per line, or as an OpenSSH Key Revocation List (KRL) as generated by ssh-keygen(1). For more information on KRLs, see the KEY REVOCATION LISTS section in ssh-keygen(1). Arguments to RevokedHostKeys may use the tilde syntax to refer to a user's home directory, the tokens described in the TOKENS section and environment variables as described in the ENVIRONMENT VARIABLES section. SecurityKeyProvider Specifies a path to a library that will be used when loading any FIDO authenticator-hosted keys, overriding the default of using the built-in USB HID support. If the specified value begins with a M-bM-^@M-^X$M-bM-^@M-^Y character, then it will be treated as an environment variable containing the path to the library. SendEnv Specifies what variables from the local environ(7) should be sent to the server. The server must also support it, and the server must be configured to accept these environment variables. Note that the TERM environment variable is always sent whenever a pseudo-terminal is requested as it is required by the protocol. Refer to AcceptEnv in sshd_config(5) for how to configure the server. Variables are specified by name, which may contain wildcard characters. Multiple environment variables may be separated by whitespace or spread across multiple SendEnv directives. See PATTERNS for more information on patterns. It is possible to clear previously set SendEnv variable names by prefixing patterns with -. The default is not to send any environment variables. ServerAliveCountMax Sets the number of server alive messages (see below) which may be sent without ssh(1) receiving any messages back from the server. If this threshold is reached while server alive messages are being sent, ssh will disconnect from the server, terminating the session. It is important to note that the use of server alive messages is very different from TCPKeepAlive (below). The server alive messages are sent through the encrypted channel and therefore will not be spoofable. The TCP keepalive option enabled by TCPKeepAlive is spoofable. The server alive mechanism is valuable when the client or server depend on knowing when a connection has become unresponsive. The default value is 3. If, for example, ServerAliveInterval (see below) is set to 15 and ServerAliveCountMax is left at the default, if the server becomes unresponsive, ssh will disconnect after approximately 45 seconds. ServerAliveInterval Sets a timeout interval in seconds after which if no data has been received from the server, ssh(1) will send a message through the encrypted channel to request a response from the server. The default is 0, indicating that these messages will not be sent to the server. SessionType May be used to either request invocation of a subsystem on the remote system, or to prevent the execution of a remote command at all. The latter is useful for just forwarding ports. The argument to this keyword must be none (same as the -N option), subsystem (same as the -s option) or default (shell or command execution). SetEnv Directly specify one or more environment variables and their contents to be sent to the server. Similarly to SendEnv, with the exception of the TERM variable, the server must be prepared to accept the environment variable. StdinNull Redirects stdin from /dev/null (actually, prevents reading from stdin). Either this or the equivalent -n option must be used when ssh is run in the background. The argument to this keyword must be yes (same as the -n option) or no (the default). StreamLocalBindMask Sets the octal file creation mode mask (umask) used when creating a Unix-domain socket file for local or remote port forwarding. This option is only used for port forwarding to a Unix-domain socket file. The default value is 0177, which creates a Unix-domain socket file that is readable and writable only by the owner. Note that not all operating systems honor the file mode on Unix-domain socket files. StreamLocalBindUnlink Specifies whether to remove an existing Unix-domain socket file for local or remote port forwarding before creating a new one. If the socket file already exists and StreamLocalBindUnlink is not enabled, ssh will be unable to forward the port to the Unix- domain socket file. This option is only used for port forwarding to a Unix-domain socket file. The argument must be yes or no (the default). StrictHostKeyChecking If this flag is set to yes, ssh(1) will never automatically add host keys to the ~/.ssh/known_hosts file, and refuses to connect to hosts whose host key has changed. This provides maximum protection against man-in-the-middle (MITM) attacks, though it can be annoying when the /etc/ssh/ssh_known_hosts file is poorly maintained or when connections to new hosts are frequently made. This option forces the user to manually add all new hosts. If this flag is set to accept-new then ssh will automatically add new host keys to the user's known_hosts file, but will not permit connections to hosts with changed host keys. If this flag is set to no or off, ssh will automatically add new host keys to the user known hosts files and allow connections to hosts with changed hostkeys to proceed, subject to some restrictions. If this flag is set to ask (the default), new host keys will be added to the user known host files only after the user has confirmed that is what they really want to do, and ssh will refuse to connect to hosts whose host key has changed. The host keys of known hosts will be verified automatically in all cases. SyslogFacility Gives the facility code that is used when logging messages from ssh(1). The possible values are: DAEMON, USER, AUTH, LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7. The default is USER. TCPKeepAlive Specifies whether the system should send TCP keepalive messages to the other side. If they are sent, death of the connection or crash of one of the machines will be properly noticed. However, this means that connections will die if the route is down temporarily, and some people find it annoying. The default is yes (to send TCP keepalive messages), and the client will notice if the network goes down or the remote host dies. This is important in scripts, and many users want it too. To disable TCP keepalive messages, the value should be set to no. See also ServerAliveInterval for protocol-level keepalives. Tag Specify a configuration tag name that may be later used by a Match directive to select a block of configuration. Tunnel Request tun(4) device forwarding between the client and the server. The argument must be yes, point-to-point (layer 3), ethernet (layer 2), or no (the default). Specifying yes requests the default tunnel mode, which is point-to-point. TunnelDevice Specifies the tun(4) devices to open on the client (local_tun) and the server (remote_tun). The argument must be local_tun[:remote_tun]. The devices may be specified by numerical ID or the keyword any, which uses the next available tunnel device. If remote_tun is not specified, it defaults to any. The default is any:any. UpdateHostKeys Specifies whether ssh(1) should accept notifications of additional hostkeys from the server sent after authentication has completed and add them to UserKnownHostsFile. The argument must be yes, no or ask. This option allows learning alternate hostkeys for a server and supports graceful key rotation by allowing a server to send replacement public keys before old ones are removed. Additional hostkeys are only accepted if the key used to authenticate the host was already trusted or explicitly accepted by the user, the host was authenticated via UserKnownHostsFile (i.e. not GlobalKnownHostsFile) and the host was authenticated using a plain key and not a certificate. UpdateHostKeys is enabled by default if the user has not overridden the default UserKnownHostsFile setting and has not enabled VerifyHostKeyDNS, otherwise UpdateHostKeys will be set to no. If UpdateHostKeys is set to ask, then the user is asked to confirm the modifications to the known_hosts file. Confirmation is currently incompatible with ControlPersist, and will be disabled if it is enabled. Presently, only sshd(8) from OpenSSH 6.8 and greater support the "hostkeys@openssh.com" protocol extension used to inform the client of all the server's hostkeys. User Specifies the user to log in as. This can be useful when a different user name is used on different machines. This saves the trouble of having to remember to give the user name on the command line. UserKnownHostsFile Specifies one or more files to use for the user host key database, separated by whitespace. Each filename may use tilde notation to refer to the user's home directory, the tokens described in the TOKENS section and environment variables as described in the ENVIRONMENT VARIABLES section. A value of none causes ssh(1) to ignore any user-specific known hosts files. The default is ~/.ssh/known_hosts, ~/.ssh/known_hosts2. VerifyHostKeyDNS Specifies whether to verify the remote key using DNS and SSHFP resource records. If this option is set to yes, the client will implicitly trust keys that match a secure fingerprint from DNS. Insecure fingerprints will be handled as if this option was set to ask. If this option is set to ask, information on fingerprint match will be displayed, but the user will still need to confirm new host keys according to the StrictHostKeyChecking option. The default is no. See also VERIFYING HOST KEYS in ssh(1). VisualHostKey If this flag is set to yes, an ASCII art representation of the remote host key fingerprint is printed in addition to the fingerprint string at login and for unknown host keys. If this flag is set to no (the default), no fingerprint strings are printed at login and only the fingerprint string will be printed for unknown host keys. XAuthLocation Specifies the full pathname of the xauth(1) program. The default is /usr/X11R6/bin/xauth. PATTERNS A pattern consists of zero or more non-whitespace characters, M-bM-^@M-^X*M-bM-^@M-^Y (a wildcard that matches zero or more characters), or M-bM-^@M-^X?M-bM-^@M-^Y (a wildcard that matches exactly one character). For example, to specify a set of declarations for any host in the ".co.uk" set of domains, the following pattern could be used: Host *.co.uk The following pattern would match any host in the 192.168.0.[0-9] network range: Host 192.168.0.? A pattern-list is a comma-separated list of patterns. Patterns within pattern-lists may be negated by preceding them with an exclamation mark (M-bM-^@M-^X!M-bM-^@M-^Y). For example, to allow a key to be used from anywhere within an organization except from the "dialup" pool, the following entry (in authorized_keys) could be used: from="!*.dialup.example.com,*.example.com" Note that a negated match will never produce a positive result by itself. For example, attempting to match "host3" against the following pattern- list will fail: from="!host1,!host2" The solution here is to include a term that will yield a positive match, such as a wildcard: from="!host1,!host2,*" TOKENS Arguments to some keywords can make use of tokens, which are expanded at runtime: %% A literal M-bM-^@M-^X%M-bM-^@M-^Y. %C Hash of %l%h%p%r%j. %d Local user's home directory. %f The fingerprint of the server's host key. %H The known_hosts hostname or address that is being searched for. %h The remote hostname. %I A string describing the reason for a KnownHostsCommand execution: either ADDRESS when looking up a host by address (only when CheckHostIP is enabled), HOSTNAME when searching by hostname, or ORDER when preparing the host key algorithm preference list to use for the destination host. %i The local user ID. %j The contents of the ProxyJump option, or the empty string if this option is unset. %K The base64 encoded host key. %k The host key alias if specified, otherwise the original remote hostname given on the command line. %L The local hostname. %l The local hostname, including the domain name. %n The original remote hostname, as given on the command line. %p The remote port. %r The remote username. %T The local tun(4) or tap(4) network interface assigned if tunnel forwarding was requested, or "NONE" otherwise. %t The type of the server host key, e.g. ssh-ed25519. %u The local username. CertificateFile, ControlPath, IdentityAgent, IdentityFile, Include, KnownHostsCommand, LocalForward, Match exec, RemoteCommand, RemoteForward, RevokedHostKeys, and UserKnownHostsFile accept the tokens %%, %C, %d, %h, %i, %j, %k, %L, %l, %n, %p, %r, and %u. KnownHostsCommand additionally accepts the tokens %f, %H, %I, %K and %t. Hostname accepts the tokens %% and %h. LocalCommand accepts all tokens. ProxyCommand and ProxyJump accept the tokens %%, %h, %n, %p, and %r. Note that some of these directives build commands for execution via the shell. Because ssh(1) performs no filtering or escaping of characters that have special meaning in shell commands (e.g. quotes), it is the user's responsibility to ensure that the arguments passed to ssh(1) do not contain such characters and that tokens are appropriately quoted when used. ENVIRONMENT VARIABLES Arguments to some keywords can be expanded at runtime from environment variables on the client by enclosing them in ${}, for example ${HOME}/.ssh would refer to the user's .ssh directory. If a specified environment variable does not exist then an error will be returned and the setting for that keyword will be ignored. The keywords CertificateFile, ControlPath, IdentityAgent, IdentityFile, Include, KnownHostsCommand, and UserKnownHostsFile support environment variables. The keywords LocalForward and RemoteForward support environment variables only for Unix domain socket paths. FILES ~/.ssh/config This is the per-user configuration file. The format of this file is described above. This file is used by the SSH client. Because of the potential for abuse, this file must have strict permissions: read/write for the user, and not writable by others. /etc/ssh/ssh_config Systemwide configuration file. This file provides defaults for those values that are not specified in the user's configuration file, and for those users who do not have a configuration file. This file must be world-readable.

It provides secure encrypted communications between two untrusted hosts over an insecure network. sshd listens for connections from clients. It is normally started at boot from /etc/rc. It forks a new daemon for each incoming connection. The forked daemons handle key exchange, encryption, authentication, command execution, and data exchange. sshd can be configured using command-line options or a configuration file (by default sshd_config(5)); command-line options override values specified in the configuration file. sshd rereads its configuration file when it receives a hangup signal, SIGHUP, by executing itself with the name and options it was started with, e.g. /usr/sbin/sshd. The options are as follows: -4 Forces sshd to use IPv4 addresses only. -6 Forces sshd to use IPv6 addresses only. -C connection_spec Specify the connection parameters to use for the -T extended test mode. If provided, any Match directives in the configuration file that would apply are applied before the configuration is written to standard output. The connection parameters are supplied as keyword=value pairs and may be supplied in any order, either with multiple -C options or as a comma-separated list. The keywords are M-bM-^@M-^\addrM-bM-^@M-^], M-bM-^@M-^\userM-bM-^@M-^], M-bM-^@M-^\hostM-bM-^@M-^], M-bM-^@M-^\laddrM-bM-^@M-^], M-bM-^@M-^\lportM-bM-^@M-^], and M-bM-^@M-^\rdomainM-bM-^@M-^] and correspond to source address, user, resolved source host name, local address, local port number and routing domain respectively. Additionally the M-bM-^@M-^\invalid-userM-bM-^@M-^] flag (which does not take a value argument) may be specified to simulate a connection from an unrecognised username. -c host_certificate_file Specifies a path to a certificate file to identify sshd during key exchange. The certificate file must match a host key file specified using the -h option or the HostKey configuration directive. -D When this option is specified, sshd will not detach and does not become a daemon. This allows easy monitoring of sshd. -d Debug mode. The server sends verbose debug output to standard error, and does not put itself in the background. The server also will not fork(2) and will only process one connection. This option is only intended for debugging for the server. Multiple -d options increase the debugging level. Maximum is 3. -E log_file Append debug logs to log_file instead of the system log. -e Write debug logs to standard error instead of the system log. -f config_file Specifies the name of the configuration file. The default is /etc/ssh/sshd_config. sshd refuses to start if there is no configuration file. -G Parse and print configuration file. Check the validity of the configuration file, output the effective configuration to stdout and then exit. Optionally, Match rules may be applied by specifying the connection parameters using one or more -C options. -g login_grace_time Gives the grace time for clients to authenticate themselves (default 120 seconds). If the client fails to authenticate the user within this many seconds, the server disconnects and exits. A value of zero indicates no limit. -h host_key_file Specifies a file from which a host key is read. This option must be given if sshd is not run as root (as the normal host key files are normally not readable by anyone but root). The default is /etc/ssh/ssh_host_ecdsa_key, /etc/ssh/ssh_host_ed25519_key and /etc/ssh/ssh_host_rsa_key. It is possible to have multiple host key files for the different host key algorithms. -i Specifies that sshd is being run from inetd(8). -o option Can be used to give options in the format used in the configuration file. This is useful for specifying options for which there is no separate command-line flag. For full details of the options, and their values, see sshd_config(5). -p port Specifies the port on which the server listens for connections (default 22). Multiple port options are permitted. Ports specified in the configuration file with the Port option are ignored when a command-line port is specified. Ports specified using the ListenAddress option override command-line ports. -q Quiet mode. Nothing is sent to the system log. Normally the beginning, authentication, and termination of each connection is logged. -T Extended test mode. Check the validity of the configuration file, output the effective configuration to stdout and then exit. Optionally, Match rules may be applied by specifying the connection parameters using one or more -C options. This is similar to the -G flag, but it includes the additional testing performed by the -t flag. -t Test mode. Only check the validity of the configuration file and sanity of the keys. This is useful for updating sshd reliably as configuration options may change. -u len This option is used to specify the size of the field in the utmp structure that holds the remote host name. If the resolved host name is longer than len, the dotted decimal value will be used instead. This allows hosts with very long host names that overflow this field to still be uniquely identified. Specifying -u0 indicates that only dotted decimal addresses should be put into the utmp file. -u0 may also be used to prevent sshd from making DNS requests unless the authentication mechanism or configuration requires it. Authentication mechanisms that may require DNS include HostbasedAuthentication and using a from="pattern-list" option in a key file. Configuration options that require DNS include using a USER@HOST pattern in AllowUsers or DenyUsers. -V Display the version number and exit. AUTHENTICATION The OpenSSH SSH daemon supports SSH protocol 2 only. Each host has a host-specific key, used to identify the host. Whenever a client connects, the daemon responds with its public host key. The client compares the host key against its own database to verify that it has not changed. Forward secrecy is provided through a Diffie-Hellman key agreement. This key agreement results in a shared session key. The rest of the session is encrypted using a symmetric cipher. The client selects the encryption algorithm to use from those offered by the server. Additionally, session integrity is provided through a cryptographic message authentication code (MAC). Finally, the server and the client enter an authentication dialog. The client tries to authenticate itself using host-based authentication, public key authentication, challenge-response authentication, or password authentication. Regardless of the authentication type, the account is checked to ensure that it is accessible. An account is not accessible if it is locked, listed in DenyUsers or its group is listed in DenyGroups . The definition of a locked account is system dependent. Some platforms have their own account database (eg AIX) and some modify the passwd field ( M-bM-^@M-^X*LK*M-bM-^@M-^Y on Solaris and UnixWare, M-bM-^@M-^X*M-bM-^@M-^Y on HP-UX, containing M-bM-^@M-^XNologinM-bM-^@M-^Y on Tru64, a leading M-bM-^@M-^X*LOCKED*M-bM-^@M-^Y on FreeBSD and a leading M-bM-^@M-^X!M-bM-^@M-^Y on most Linuxes). If there is a requirement to disable password authentication for the account while allowing still public-key, then the passwd field should be set to something other than these values (eg M-bM-^@M-^XNPM-bM-^@M-^Y or M-bM-^@M-^X*NP*M-bM-^@M-^Y ). If the client successfully authenticates itself, a dialog for preparing the session is entered. At this time the client may request things like allocating a pseudo-tty, forwarding X11 connections, forwarding TCP connections, or forwarding the authentication agent connection over the secure channel. After this, the client either requests an interactive shell or execution of a non-interactive command, which sshd will execute via the user's shell using its -c option. The sides then enter session mode. In this mode, either side may send data at any time, and such data is forwarded to/from the shell or command on the server side, and the user terminal in the client side. When the user program terminates and all forwarded X11 and other connections have been closed, the server sends command exit status to the client, and both sides exit. LOGIN PROCESS When a user successfully logs in, sshd does the following: 1. If the login is on a tty, and no command has been specified, prints last login time and /etc/motd (unless prevented in the configuration file or by ~/.hushlogin; see the FILES section). 2. If the login is on a tty, records login time. 3. Checks /etc/nologin; if it exists, prints contents and quits (unless root). 4. Changes to run with normal user privileges. 5. Sets up basic environment. 6. Reads the file ~/.ssh/environment, if it exists, and users are allowed to change their environment. See the PermitUserEnvironment option in sshd_config(5). 7. Changes to user's home directory. 8. If ~/.ssh/rc exists and the sshd_config(5) PermitUserRC option is set, runs it; else if /etc/ssh/sshrc exists, runs it; otherwise runs xauth(1). The M-bM-^@M-^\rcM-bM-^@M-^] files are given the X11 authentication protocol and cookie in standard input. See SSHRC, below. 9. Runs user's shell or command. All commands are run under the user's login shell as specified in the system password database. SSHRC If the file ~/.ssh/rc exists, sh(1) runs it after reading the environment files but before starting the user's shell or command. It must not produce any output on stdout; stderr must be used instead. If X11 forwarding is in use, it will receive the "proto cookie" pair in its standard input (and DISPLAY in its environment). The script must call xauth(1) because sshd will not run xauth automatically to add X11 cookies. The primary purpose of this file is to run any initialization routines which may be needed before the user's home directory becomes accessible; AFS is a particular example of such an environment. This file will probably contain some initialization code followed by something similar to: if read proto cookie && [ -n "$DISPLAY" ]; then if [ `echo $DISPLAY | cut -c1-10` = 'localhost:' ]; then # X11UseLocalhost=yes echo add unix:`echo $DISPLAY | cut -c11-` $proto $cookie else # X11UseLocalhost=no echo add $DISPLAY $proto $cookie fi | xauth -q - fi If this file does not exist, /etc/ssh/sshrc is run, and if that does not exist either, xauth is used to add the cookie. AUTHORIZED_KEYS FILE FORMAT AuthorizedKeysFile specifies the files containing public keys for public key authentication; if this option is not specified, the default is ~/.ssh/authorized_keys and ~/.ssh/authorized_keys2. Each line of the file contains one key (empty lines and lines starting with a M-bM-^@M-^X#M-bM-^@M-^Y are ignored as comments). Public keys consist of the following space- separated fields: options, keytype, base64-encoded key, comment. The options field is optional. The supported key types are: sk-ecdsa-sha2-nistp256@openssh.com ecdsa-sha2-nistp256 ecdsa-sha2-nistp384 ecdsa-sha2-nistp521 sk-ssh-ed25519@openssh.com ssh-ed25519 ssh-rsa The comment field is not used for anything (but may be convenient for the user to identify the key). Note that lines in this file can be several hundred bytes long (because of the size of the public key encoding) up to a limit of 8 kilobytes, which permits RSA keys up to 16 kilobits. You don't want to type them in; instead, copy the id_ecdsa.pub, id_ecdsa_sk.pub, id_ed25519.pub, id_ed25519_sk.pub, or the id_rsa.pub file and edit it. sshd enforces a minimum RSA key modulus size of 1024 bits. The options (if present) consist of comma-separated option specifications. No spaces are permitted, except within double quotes. The following option specifications are supported (note that option keywords are case-insensitive): agent-forwarding Enable authentication agent forwarding previously disabled by the restrict option. cert-authority Specifies that the listed key is a certification authority (CA) that is trusted to validate signed certificates for user authentication. Certificates may encode access restrictions similar to these key options. If both certificate restrictions and key options are present, the most restrictive union of the two is applied. command="command" Specifies that the command is executed whenever this key is used for authentication. The command supplied by the user (if any) is ignored. The command is run on a pty if the client requests a pty; otherwise it is run without a tty. If an 8-bit clean channel is required, one must not request a pty or should specify no-pty. A quote may be included in the command by quoting it with a backslash. This option might be useful to restrict certain public keys to perform just a specific operation. An example might be a key that permits remote backups but nothing else. Note that the client may specify TCP and/or X11 forwarding unless they are explicitly prohibited, e.g. using the restrict key option. The command originally supplied by the client is available in the SSH_ORIGINAL_COMMAND environment variable. Note that this option applies to shell, command or subsystem execution. Also note that this command may be superseded by a sshd_config(5) ForceCommand directive. If a command is specified and a forced-command is embedded in a certificate used for authentication, then the certificate will be accepted only if the two commands are identical. environment="NAME=value" Specifies that the string is to be added to the environment when logging in using this key. Environment variables set this way override other default environment values. Multiple options of this type are permitted. Environment processing is disabled by default and is controlled via the PermitUserEnvironment option. expiry-time="timespec" Specifies a time after which the key will not be accepted. The time may be specified as a YYYYMMDD[Z] date or a YYYYMMDDHHMM[SS][Z] time. Dates and times will be interpreted in the system time zone unless suffixed by a Z character, in which case they will be interpreted in the UTC time zone. from="pattern-list" Specifies that in addition to public key authentication, either the canonical name of the remote host or its IP address must be present in the comma-separated list of patterns. See PATTERNS in ssh_config(5) for more information on patterns. In addition to the wildcard matching that may be applied to hostnames or addresses, a from stanza may match IP addresses using CIDR address/masklen notation. The purpose of this option is to optionally increase security: public key authentication by itself does not trust the network or name servers or anything (but the key); however, if somebody somehow steals the key, the key permits an intruder to log in from anywhere in the world. This additional option makes using a stolen key more difficult (name servers and/or routers would have to be compromised in addition to just the key). no-agent-forwarding Forbids authentication agent forwarding when this key is used for authentication. no-port-forwarding Forbids TCP forwarding when this key is used for authentication. Any port forward requests by the client will return an error. This might be used, e.g. in connection with the command option. no-pty Prevents tty allocation (a request to allocate a pty will fail). no-user-rc Disables execution of ~/.ssh/rc. no-X11-forwarding Forbids X11 forwarding when this key is used for authentication. Any X11 forward requests by the client will return an error. permitlisten="[host:]port" Limit remote port forwarding with the ssh(1) -R option such that it may only listen on the specified host (optional) and port. IPv6 addresses can be specified by enclosing the address in square brackets. Multiple permitlisten options may be applied separated by commas. Hostnames may include wildcards as described in the PATTERNS section in ssh_config(5). A port specification of * matches any port. Note that the setting of GatewayPorts may further restrict listen addresses. Note that ssh(1) will send a hostname of M-bM-^@M-^\localhostM-bM-^@M-^] if a listen host was not specified when the forwarding was requested, and that this name is treated differently to the explicit localhost addresses M-bM-^@M-^\127.0.0.1M-bM-^@M-^] and M-bM-^@M-^\::1M-bM-^@M-^]. permitopen="host:port" Limit local port forwarding with the ssh(1) -L option such that it may only connect to the specified host and port. IPv6 addresses can be specified by enclosing the address in square brackets. Multiple permitopen options may be applied separated by commas. No pattern matching or name lookup is performed on the specified hostnames, they must be literal host names and/or addresses. A port specification of * matches any port. port-forwarding Enable port forwarding previously disabled by the restrict option. principals="principals" On a cert-authority line, specifies allowed principals for certificate authentication as a comma-separated list. At least one name from the list must appear in the certificate's list of principals for the certificate to be accepted. This option is ignored for keys that are not marked as trusted certificate signers using the cert-authority option. pty Permits tty allocation previously disabled by the restrict option. no-touch-required Do not require demonstration of user presence for signatures made using this key. This option only makes sense for the FIDO authenticator algorithms ecdsa-sk and ed25519-sk. verify-required Require that signatures made using this key attest that they verified the user, e.g. via a PIN. This option only makes sense for the FIDO authenticator algorithms ecdsa-sk and ed25519-sk. restrict Enable all restrictions, i.e. disable port, agent and X11 forwarding, as well as disabling PTY allocation and execution of ~/.ssh/rc. If any future restriction capabilities are added to authorized_keys files, they will be included in this set. tunnel="n" Force a tun(4) device on the server. Without this option, the next available device will be used if the client requests a tunnel. user-rc Enables execution of ~/.ssh/rc previously disabled by the restrict option. X11-forwarding Permits X11 forwarding previously disabled by the restrict option. An example authorized_keys file: # Comments are allowed at start of line. Blank lines are allowed. # Plain key, no restrictions ssh-rsa ... # Forced command, disable PTY and all forwarding restrict,command="dump /home" ssh-rsa ... # Restriction of ssh -L forwarding destinations permitopen="192.0.2.1:80",permitopen="192.0.2.2:25" ssh-rsa ... # Restriction of ssh -R forwarding listeners permitlisten="localhost:8080",permitlisten="[::1]:22000" ssh-rsa ... # Configuration for tunnel forwarding tunnel="0",command="sh /etc/netstart tun0" ssh-rsa ... # Override of restriction to allow PTY allocation restrict,pty,command="nethack" ssh-rsa ... # Allow FIDO key without requiring touch no-touch-required sk-ecdsa-sha2-nistp256@openssh.com ... # Require user-verification (e.g. PIN or biometric) for FIDO key verify-required sk-ecdsa-sha2-nistp256@openssh.com ... # Trust CA key, allow touch-less FIDO if requested in certificate cert-authority,no-touch-required,principals="user_a" ssh-rsa ... SSH_KNOWN_HOSTS FILE FORMAT The /etc/ssh/ssh_known_hosts and ~/.ssh/known_hosts files contain host public keys for all known hosts. The global file should be prepared by the administrator (optional), and the per-user file is maintained automatically: whenever the user connects to an unknown host, its key is added to the per-user file. Each line in these files contains the following fields: marker (optional), hostnames, keytype, base64-encoded key, comment. The fields are separated by spaces. The marker is optional, but if it is present then it must be one of M-bM-^@M-^\@cert-authorityM-bM-^@M-^], to indicate that the line contains a certification authority (CA) key, or M-bM-^@M-^\@revokedM-bM-^@M-^], to indicate that the key contained on the line is revoked and must not ever be accepted. Only one marker should be used on a key line. Hostnames is a comma-separated list of patterns (M-bM-^@M-^X*M-bM-^@M-^Y and M-bM-^@M-^X?M-bM-^@M-^Y act as wildcards); each pattern in turn is matched against the host name. When sshd is authenticating a client, such as when using HostbasedAuthentication, this will be the canonical client host name. When ssh(1) is authenticating a server, this will be the host name given by the user, the value of the ssh(1) HostkeyAlias if it was specified, or the canonical server hostname if the ssh(1) CanonicalizeHostname option was used. A pattern may also be preceded by M-bM-^@M-^X!M-bM-^@M-^Y to indicate negation: if the host name matches a negated pattern, it is not accepted (by that line) even if it matched another pattern on the line. A hostname or address may optionally be enclosed within M-bM-^@M-^X[M-bM-^@M-^Y and M-bM-^@M-^X]M-bM-^@M-^Y brackets then followed by M-bM-^@M-^X:M-bM-^@M-^Y and a non-standard port number. Alternately, hostnames may be stored in a hashed form which hides host names and addresses should the file's contents be disclosed. Hashed hostnames start with a M-bM-^@M-^X|M-bM-^@M-^Y character. Only one hashed hostname may appear on a single line and none of the above negation or wildcard operators may be applied. The keytype and base64-encoded key are taken directly from the host key; they can be obtained, for example, from /etc/ssh/ssh_host_rsa_key.pub. The optional comment field continues to the end of the line, and is not used. Lines starting with M-bM-^@M-^X#M-bM-^@M-^Y and empty lines are ignored as comments. When performing host authentication, authentication is accepted if any matching line has the proper key; either one that matches exactly or, if the server has presented a certificate for authentication, the key of the certification authority that signed the certificate. For a key to be trusted as a certification authority, it must use the M-bM-^@M-^\@cert-authorityM-bM-^@M-^] marker described above. The known hosts file also provides a facility to mark keys as revoked, for example when it is known that the associated private key has been stolen. Revoked keys are specified by including the M-bM-^@M-^\@revokedM-bM-^@M-^] marker at the beginning of the key line, and are never accepted for authentication or as certification authorities, but instead will produce a warning from ssh(1) when they are encountered. It is permissible (but not recommended) to have several lines or different host keys for the same names. This will inevitably happen when short forms of host names from different domains are put in the file. It is possible that the files contain conflicting information; authentication is accepted if valid information can be found from either file. Note that the lines in these files are typically hundreds of characters long, and you definitely don't want to type in the host keys by hand. Rather, generate them by a script, ssh-keyscan(1) or by taking, for example, /etc/ssh/ssh_host_rsa_key.pub and adding the host names at the front. ssh-keygen(1) also offers some basic automated editing for ~/.ssh/known_hosts including removing hosts matching a host name and converting all host names to their hashed representations. An example ssh_known_hosts file: # Comments allowed at start of line cvs.example.net,192.0.2.10 ssh-rsa AAAA1234.....= # A hashed hostname |1|JfKTdBh7rNbXkVAQCRp4OQoPfmI=|USECr3SWf1JUPsms5AqfD5QfxkM= ssh-rsa AAAA1234.....= # A revoked key @revoked * ssh-rsa AAAAB5W... # A CA key, accepted for any host in *.mydomain.com or *.mydomain.org @cert-authority *.mydomain.org,*.mydomain.com ssh-rsa AAAAB5W... FILES ~/.hushlogin This file is used to suppress printing the last login time and /etc/motd, if PrintLastLog and PrintMotd, respectively, are enabled. It does not suppress printing of the banner specified by Banner. ~/.rhosts This file is used for host-based authentication (see ssh(1) for more information). On some machines this file may need to be world-readable if the user's home directory is on an NFS partition, because sshd reads it as root. Additionally, this file must be owned by the user, and must not have write permissions for anyone else. The recommended permission for most machines is read/write for the user, and not accessible by others. ~/.shosts This file is used in exactly the same way as .rhosts, but allows host-based authentication without permitting login with rlogin/rsh. ~/.ssh/ This directory is the default location for all user-specific configuration and authentication information. There is no general requirement to keep the entire contents of this directory secret, but the recommended permissions are read/write/execute for the user, and not accessible by others. ~/.ssh/authorized_keys Lists the public keys (ECDSA, Ed25519, RSA) that can be used for logging in as this user. The format of this file is described above. The content of the file is not highly sensitive, but the recommended permissions are read/write for the user, and not accessible by others. If this file, the ~/.ssh directory, or the user's home directory are writable by other users, then the file could be modified or replaced by unauthorized users. In this case, sshd will not allow it to be used unless the StrictModes option has been set to M-bM-^@M-^\noM-bM-^@M-^]. ~/.ssh/environment This file is read into the environment at login (if it exists). It can only contain empty lines, comment lines (that start with M-bM-^@M-^X#M-bM-^@M-^Y), and assignment lines of the form name=value. The file should be writable only by the user; it need not be readable by anyone else. Environment processing is disabled by default and is controlled via the PermitUserEnvironment option. ~/.ssh/known_hosts Contains a list of host keys for all hosts the user has logged into that are not already in the systemwide list of known host keys. The format of this file is described above. This file should be writable only by root/the owner and can, but need not be, world-readable. ~/.ssh/rc Contains initialization routines to be run before the user's home directory becomes accessible. This file should be writable only by the user, and need not be readable by anyone else. /etc/hosts.equiv This file is for host-based authentication (see ssh(1)). It should only be writable by root. /etc/moduli Contains Diffie-Hellman groups used for the "Diffie-Hellman Group Exchange" key exchange method. The file format is described in moduli(5). If no usable groups are found in this file then fixed internal groups will be used. /etc/motd See motd(5). /etc/nologin If this file exists, sshd refuses to let anyone except root log in. The contents of the file are displayed to anyone trying to log in, and non-root connections are refused. The file should be world-readable. /etc/shosts.equiv This file is used in exactly the same way as hosts.equiv, but allows host-based authentication without permitting login with rlogin/rsh. /etc/ssh/ssh_host_ecdsa_key /etc/ssh/ssh_host_ed25519_key /etc/ssh/ssh_host_rsa_key These files contain the private parts of the host keys. These files should only be owned by root, readable only by root, and not accessible to others. Note that sshd does not start if these files are group/world-accessible. /etc/ssh/ssh_host_ecdsa_key.pub /etc/ssh/ssh_host_ed25519_key.pub /etc/ssh/ssh_host_rsa_key.pub These files contain the public parts of the host keys. These files should be world-readable but writable only by root. Their contents should match the respective private parts. These files are not really used for anything; they are provided for the convenience of the user so their contents can be copied to known hosts files. These files are created using ssh-keygen(1). /etc/ssh/ssh_known_hosts Systemwide list of known host keys. This file should be prepared by the system administrator to contain the public host keys of all machines in the organization. The format of this file is described above. This file should be writable only by root/the owner and should be world-readable. /etc/ssh/sshd_config Contains configuration data for sshd. The file format and configuration options are described in sshd_config(5). /etc/ssh/sshrc Similar to ~/.ssh/rc, it can be used to specify machine-specific login-time initializations globally. This file should be writable only by root, and should be world-readable. /var/empty chroot(2) directory used by sshd during privilege separation in the pre-authentication phase. The directory should not contain any files and must be owned by root and not group or world- writable. /var/run/sshd.pid Contains the process ID of the sshd listening for connections (if there are several daemons running concurrently for different ports, this contains the process ID of the one started last). The content of this file is not sensitive; it can be world- readable.

The file contains keyword- argument pairs, one per line. Unless noted otherwise, for each keyword, the first obtained value will be used. Lines starting with M-bM-^@M-^X#M-bM-^@M-^Y and empty lines are interpreted as comments. Arguments may optionally be enclosed in double quotes (") in order to represent arguments containing spaces. The possible keywords and their meanings are as follows (note that keywords are case-insensitive and arguments are case-sensitive): AcceptEnv Specifies what environment variables sent by the client will be copied into the session's environ(7). See SendEnv and SetEnv in ssh_config(5) for how to configure the client. The TERM environment variable is always accepted whenever the client requests a pseudo-terminal as it is required by the protocol. Variables are specified by name, which may contain the wildcard characters M-bM-^@M-^X*M-bM-^@M-^Y and M-bM-^@M-^X?M-bM-^@M-^Y. Multiple environment variables may be separated by whitespace or spread across multiple AcceptEnv directives. Be warned that some environment variables could be used to bypass restricted user environments. For this reason, care should be taken in the use of this directive. The default is not to accept any environment variables. AddressFamily Specifies which address family should be used by sshd(8). Valid arguments are any (the default), inet (use IPv4 only), or inet6 (use IPv6 only). AllowAgentForwarding Specifies whether ssh-agent(1) forwarding is permitted. The default is yes. Note that disabling agent forwarding does not improve security unless users are also denied shell access, as they can always install their own forwarders. AllowGroups This keyword can be followed by a list of group name patterns, separated by spaces. If specified, login is allowed only for users whose primary group or supplementary group list matches one of the patterns. Only group names are valid; a numerical group ID is not recognized. By default, login is allowed for all groups. The allow/deny groups directives are processed in the following order: DenyGroups, AllowGroups. See PATTERNS in ssh_config(5) for more information on patterns. This keyword may appear multiple times in sshd_config with each instance appending to the list. AllowStreamLocalForwarding Specifies whether StreamLocal (Unix-domain socket) forwarding is permitted. The available options are yes (the default) or all to allow StreamLocal forwarding, no to prevent all StreamLocal forwarding, local to allow local (from the perspective of ssh(1)) forwarding only or remote to allow remote forwarding only. Note that disabling StreamLocal forwarding does not improve security unless users are also denied shell access, as they can always install their own forwarders. AllowTcpForwarding Specifies whether TCP forwarding is permitted. The available options are yes (the default) or all to allow TCP forwarding, no to prevent all TCP forwarding, local to allow local (from the perspective of ssh(1)) forwarding only or remote to allow remote forwarding only. Note that disabling TCP forwarding does not improve security unless users are also denied shell access, as they can always install their own forwarders. AllowUsers This keyword can be followed by a list of user name patterns, separated by spaces. If specified, login is allowed only for user names that match one of the patterns. Only user names are valid; a numerical user ID is not recognized. By default, login is allowed for all users. If the pattern takes the form USER@HOST then USER and HOST are separately checked, restricting logins to particular users from particular hosts. HOST criteria may additionally contain addresses to match in CIDR address/masklen format. The allow/deny users directives are processed in the following order: DenyUsers, AllowUsers. See PATTERNS in ssh_config(5) for more information on patterns. This keyword may appear multiple times in sshd_config with each instance appending to the list. AuthenticationMethods Specifies the authentication methods that must be successfully completed for a user to be granted access. This option must be followed by one or more lists of comma-separated authentication method names, or by the single string any to indicate the default behaviour of accepting any single authentication method. If the default is overridden, then successful authentication requires completion of every method in at least one of these lists. For example, "publickey,password publickey,keyboard-interactive" would require the user to complete public key authentication, followed by either password or keyboard interactive authentication. Only methods that are next in one or more lists are offered at each stage, so for this example it would not be possible to attempt password or keyboard-interactive authentication before public key. For keyboard interactive authentication it is also possible to restrict authentication to a specific device by appending a colon followed by the device identifier bsdauth or pam. depending on the server configuration. For example, "keyboard-interactive:bsdauth" would restrict keyboard interactive authentication to the bsdauth device. If the publickey method is listed more than once, sshd(8) verifies that keys that have been used successfully are not reused for subsequent authentications. For example, "publickey,publickey" requires successful authentication using two different public keys. Note that each authentication method listed should also be explicitly enabled in the configuration. The available authentication methods are: "gssapi-with-mic", "hostbased", "keyboard-interactive", "none" (used for access to password-less accounts when PermitEmptyPasswords is enabled), "password" and "publickey". AuthorizedKeysCommand Specifies a program to be used to look up the user's public keys. The program must be owned by root, not writable by group or others and specified by an absolute path. Arguments to AuthorizedKeysCommand accept the tokens described in the TOKENS section. If no arguments are specified then the username of the target user is used. The program should produce on standard output zero or more lines of authorized_keys output (see AUTHORIZED_KEYS in sshd(8)). AuthorizedKeysCommand is tried after the usual AuthorizedKeysFile files and will not be executed if a matching key is found there. By default, no AuthorizedKeysCommand is run. AuthorizedKeysCommandUser Specifies the user under whose account the AuthorizedKeysCommand is run. It is recommended to use a dedicated user that has no other role on the host than running authorized keys commands. If AuthorizedKeysCommand is specified but AuthorizedKeysCommandUser is not, then sshd(8) will refuse to start. AuthorizedKeysFile Specifies the file that contains the public keys used for user authentication. The format is described in the AUTHORIZED_KEYS FILE FORMAT section of sshd(8). Arguments to AuthorizedKeysFile accept the tokens described in the TOKENS section. After expansion, AuthorizedKeysFile is taken to be an absolute path or one relative to the user's home directory. Multiple files may be listed, separated by whitespace. Alternately this option may be set to none to skip checking for user keys in files. The default is ".ssh/authorized_keys .ssh/authorized_keys2". AuthorizedPrincipalsCommand Specifies a program to be used to generate the list of allowed certificate principals as per AuthorizedPrincipalsFile. The program must be owned by root, not writable by group or others and specified by an absolute path. Arguments to AuthorizedPrincipalsCommand accept the tokens described in the TOKENS section. If no arguments are specified then the username of the target user is used. The program should produce on standard output zero or more lines of AuthorizedPrincipalsFile output. If either AuthorizedPrincipalsCommand or AuthorizedPrincipalsFile is specified, then certificates offered by the client for authentication must contain a principal that is listed. By default, no AuthorizedPrincipalsCommand is run. AuthorizedPrincipalsCommandUser Specifies the user under whose account the AuthorizedPrincipalsCommand is run. It is recommended to use a dedicated user that has no other role on the host than running authorized principals commands. If AuthorizedPrincipalsCommand is specified but AuthorizedPrincipalsCommandUser is not, then sshd(8) will refuse to start. AuthorizedPrincipalsFile Specifies a file that lists principal names that are accepted for certificate authentication. When using certificates signed by a key listed in TrustedUserCAKeys, this file lists names, one of which must appear in the certificate for it to be accepted for authentication. Names are listed one per line preceded by key options (as described in AUTHORIZED_KEYS FILE FORMAT in sshd(8)). Empty lines and comments starting with M-bM-^@M-^X#M-bM-^@M-^Y are ignored. Arguments to AuthorizedPrincipalsFile accept the tokens described in the TOKENS section. After expansion, AuthorizedPrincipalsFile is taken to be an absolute path or one relative to the user's home directory. The default is none, i.e. not to use a principals file M-bM-^@M-^S in this case, the username of the user must appear in a certificate's principals list for it to be accepted. Note that AuthorizedPrincipalsFile is only used when authentication proceeds using a CA listed in TrustedUserCAKeys and is not consulted for certification authorities trusted via ~/.ssh/authorized_keys, though the principals= key option offers a similar facility (see sshd(8) for details). Banner The contents of the specified file are sent to the remote user before authentication is allowed. If the argument is none then no banner is displayed. By default, no banner is displayed. CASignatureAlgorithms Specifies which algorithms are allowed for signing of certificates by certificate authorities (CAs). The default is: ssh-ed25519,ecdsa-sha2-nistp256, ecdsa-sha2-nistp384,ecdsa-sha2-nistp521, sk-ssh-ed25519@openssh.com, sk-ecdsa-sha2-nistp256@openssh.com, rsa-sha2-512,rsa-sha2-256 If the specified list begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified algorithms will be appended to the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified algorithms (including wildcards) will be removed from the default set instead of replacing them. Certificates signed using other algorithms will not be accepted for public key or host-based authentication. ChannelTimeout Specifies whether and how quickly sshd(8) should close inactive channels. Timeouts are specified as one or more M-bM-^@M-^\type=intervalM-bM-^@M-^] pairs separated by whitespace, where the M-bM-^@M-^\typeM-bM-^@M-^] must be the special keyword M-bM-^@M-^\globalM-bM-^@M-^] or a channel type name from the list below, optionally containing wildcard characters. The timeout value M-bM-^@M-^\intervalM-bM-^@M-^] is specified in seconds or may use any of the units documented in the TIME FORMATS section. For example, M-bM-^@M-^\session=5mM-bM-^@M-^] would cause interactive sessions to terminate after five minutes of inactivity. Specifying a zero value disables the inactivity timeout. The special timeout M-bM-^@M-^\globalM-bM-^@M-^] applies to all active channels, taken together. Traffic on any active channel will reset the timeout, but when the timeout expires then all open channels will be closed. Note that this global timeout is not matched by wildcards and must be specified explicitly. The available channel type names include: agent-connection Open connections to ssh-agent(1). direct-tcpip, direct-streamlocal@openssh.com Open TCP or Unix socket (respectively) connections that have been established from a ssh(1) local forwarding, i.e. LocalForward or DynamicForward. forwarded-tcpip, forwarded-streamlocal@openssh.com Open TCP or Unix socket (respectively) connections that have been established to a sshd(8) listening on behalf of a ssh(1) remote forwarding, i.e. RemoteForward. session The interactive main session, including shell session, command execution, scp(1), sftp(1), etc. tun-connection Open TunnelForward connections. x11-connection Open X11 forwarding sessions. Note that in all the above cases, terminating an inactive session does not guarantee to remove all resources associated with the session, e.g. shell processes or X11 clients relating to the session may continue to execute. Moreover, terminating an inactive channel or session does not necessarily close the SSH connection, nor does it prevent a client from requesting another channel of the same type. In particular, expiring an inactive forwarding session does not prevent another identical forwarding from being subsequently created. The default is not to expire channels of any type for inactivity. ChrootDirectory Specifies the pathname of a directory to chroot(2) to after authentication. At session startup sshd(8) checks that all components of the pathname are root-owned directories which are not writable by group or others. After the chroot, sshd(8) changes the working directory to the user's home directory. Arguments to ChrootDirectory accept the tokens described in the TOKENS section. The ChrootDirectory must contain the necessary files and directories to support the user's session. For an interactive session this requires at least a shell, typically sh(1), and basic /dev nodes such as null(4), zero(4), stdin(4), stdout(4), stderr(4), and tty(4) devices. For file transfer sessions using SFTP no additional configuration of the environment is necessary if the in-process sftp-server is used, though sessions which use logging may require /dev/log inside the chroot directory on some operating systems (see sftp-server(8) for details). For safety, it is very important that the directory hierarchy be prevented from modification by other processes on the system (especially those outside the jail). Misconfiguration can lead to unsafe environments which sshd(8) cannot detect. The default is none, indicating not to chroot(2). Ciphers Specifies the ciphers allowed. Multiple ciphers must be comma- separated. If the specified list begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified ciphers will be appended to the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified ciphers (including wildcards) will be removed from the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X^M-bM-^@M-^Y character, then the specified ciphers will be placed at the head of the default set. The supported ciphers are: 3des-cbc aes128-cbc aes192-cbc aes256-cbc aes128-ctr aes192-ctr aes256-ctr aes128-gcm@openssh.com aes256-gcm@openssh.com chacha20-poly1305@openssh.com The default is: chacha20-poly1305@openssh.com, aes128-ctr,aes192-ctr,aes256-ctr, aes128-gcm@openssh.com,aes256-gcm@openssh.com The list of available ciphers may also be obtained using "ssh -Q cipher". ClientAliveCountMax Sets the number of client alive messages which may be sent without sshd(8) receiving any messages back from the client. If this threshold is reached while client alive messages are being sent, sshd will disconnect the client, terminating the session. It is important to note that the use of client alive messages is very different from TCPKeepAlive. The client alive messages are sent through the encrypted channel and therefore will not be spoofable. The TCP keepalive option enabled by TCPKeepAlive is spoofable. The client alive mechanism is valuable when the client or server depend on knowing when a connection has become unresponsive. The default value is 3. If ClientAliveInterval is set to 15, and ClientAliveCountMax is left at the default, unresponsive SSH clients will be disconnected after approximately 45 seconds. Setting a zero ClientAliveCountMax disables connection termination. ClientAliveInterval Sets a timeout interval in seconds after which if no data has been received from the client, sshd(8) will send a message through the encrypted channel to request a response from the client. The default is 0, indicating that these messages will not be sent to the client. Compression Specifies whether compression is enabled after the user has authenticated successfully. The argument must be yes, delayed (a legacy synonym for yes) or no. The default is yes. DenyGroups This keyword can be followed by a list of group name patterns, separated by spaces. Login is disallowed for users whose primary group or supplementary group list matches one of the patterns. Only group names are valid; a numerical group ID is not recognized. By default, login is allowed for all groups. The allow/deny groups directives are processed in the following order: DenyGroups, AllowGroups. See PATTERNS in ssh_config(5) for more information on patterns. This keyword may appear multiple times in sshd_config with each instance appending to the list. DenyUsers This keyword can be followed by a list of user name patterns, separated by spaces. Login is disallowed for user names that match one of the patterns. Only user names are valid; a numerical user ID is not recognized. By default, login is allowed for all users. If the pattern takes the form USER@HOST then USER and HOST are separately checked, restricting logins to particular users from particular hosts. HOST criteria may additionally contain addresses to match in CIDR address/masklen format. The allow/deny users directives are processed in the following order: DenyUsers, AllowUsers. See PATTERNS in ssh_config(5) for more information on patterns. This keyword may appear multiple times in sshd_config with each instance appending to the list. DisableForwarding Disables all forwarding features, including X11, ssh-agent(1), TCP and StreamLocal. This option overrides all other forwarding- related options and may simplify restricted configurations. ExposeAuthInfo Writes a temporary file containing a list of authentication methods and public credentials (e.g. keys) used to authenticate the user. The location of the file is exposed to the user session through the SSH_USER_AUTH environment variable. The default is no. FingerprintHash Specifies the hash algorithm used when logging key fingerprints. Valid options are: md5 and sha256. The default is sha256. ForceCommand Forces the execution of the command specified by ForceCommand, ignoring any command supplied by the client and ~/.ssh/rc if present. The command is invoked by using the user's login shell with the -c option. This applies to shell, command, or subsystem execution. It is most useful inside a Match block. The command originally supplied by the client is available in the SSH_ORIGINAL_COMMAND environment variable. Specifying a command of internal-sftp will force the use of an in-process SFTP server that requires no support files when used with ChrootDirectory. The default is none. GatewayPorts Specifies whether remote hosts are allowed to connect to ports forwarded for the client. By default, sshd(8) binds remote port forwardings to the loopback address. This prevents other remote hosts from connecting to forwarded ports. GatewayPorts can be used to specify that sshd should allow remote port forwardings to bind to non-loopback addresses, thus allowing other hosts to connect. The argument may be no to force remote port forwardings to be available to the local host only, yes to force remote port forwardings to bind to the wildcard address, or clientspecified to allow the client to select the address to which the forwarding is bound. The default is no. GSSAPIAuthentication Specifies whether user authentication based on GSSAPI is allowed. The default is no. GSSAPICleanupCredentials Specifies whether to automatically destroy the user's credentials cache on logout. The default is yes. GSSAPIStrictAcceptorCheck Determines whether to be strict about the identity of the GSSAPI acceptor a client authenticates against. If set to yes then the client must authenticate against the host service on the current hostname. If set to no then the client may authenticate against any service key stored in the machine's default store. This facility is provided to assist with operation on multi homed machines. The default is yes. HostbasedAcceptedAlgorithms Specifies the signature algorithms that will be accepted for hostbased authentication as a list of comma-separated patterns. Alternately if the specified list begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified signature algorithms will be appended to the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified signature algorithms (including wildcards) will be removed from the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X^M-bM-^@M-^Y character, then the specified signature algorithms will be placed at the head of the default set. The default for this option is: ssh-ed25519-cert-v01@openssh.com, ecdsa-sha2-nistp256-cert-v01@openssh.com, ecdsa-sha2-nistp384-cert-v01@openssh.com, ecdsa-sha2-nistp521-cert-v01@openssh.com, sk-ssh-ed25519-cert-v01@openssh.com, sk-ecdsa-sha2-nistp256-cert-v01@openssh.com, rsa-sha2-512-cert-v01@openssh.com, rsa-sha2-256-cert-v01@openssh.com, ssh-ed25519, ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521, sk-ssh-ed25519@openssh.com, sk-ecdsa-sha2-nistp256@openssh.com, rsa-sha2-512,rsa-sha2-256 The list of available signature algorithms may also be obtained using "ssh -Q HostbasedAcceptedAlgorithms". This was formerly named HostbasedAcceptedKeyTypes. HostbasedAuthentication Specifies whether rhosts or /etc/hosts.equiv authentication together with successful public key client host authentication is allowed (host-based authentication). The default is no. HostbasedUsesNameFromPacketOnly Specifies whether or not the server will attempt to perform a reverse name lookup when matching the name in the ~/.shosts, ~/.rhosts, and /etc/hosts.equiv files during HostbasedAuthentication. A setting of yes means that sshd(8) uses the name supplied by the client rather than attempting to resolve the name from the TCP connection itself. The default is no. HostCertificate Specifies a file containing a public host certificate. The certificate's public key must match a private host key already specified by HostKey. The default behaviour of sshd(8) is not to load any certificates. HostKey Specifies a file containing a private host key used by SSH. The defaults are /etc/ssh/ssh_host_ecdsa_key, /etc/ssh/ssh_host_ed25519_key and /etc/ssh/ssh_host_rsa_key. Note that sshd(8) will refuse to use a file if it is group/world- accessible and that the HostKeyAlgorithms option restricts which of the keys are actually used by sshd(8). It is possible to have multiple host key files. It is also possible to specify public host key files instead. In this case operations on the private key will be delegated to an ssh-agent(1). HostKeyAgent Identifies the UNIX-domain socket used to communicate with an agent that has access to the private host keys. If the string "SSH_AUTH_SOCK" is specified, the location of the socket will be read from the SSH_AUTH_SOCK environment variable. HostKeyAlgorithms Specifies the host key signature algorithms that the server offers. The default for this option is: ssh-ed25519-cert-v01@openssh.com, ecdsa-sha2-nistp256-cert-v01@openssh.com, ecdsa-sha2-nistp384-cert-v01@openssh.com, ecdsa-sha2-nistp521-cert-v01@openssh.com, sk-ssh-ed25519-cert-v01@openssh.com, sk-ecdsa-sha2-nistp256-cert-v01@openssh.com, rsa-sha2-512-cert-v01@openssh.com, rsa-sha2-256-cert-v01@openssh.com, ssh-ed25519, ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521, sk-ssh-ed25519@openssh.com, sk-ecdsa-sha2-nistp256@openssh.com, rsa-sha2-512,rsa-sha2-256 The list of available signature algorithms may also be obtained using "ssh -Q HostKeyAlgorithms". IgnoreRhosts Specifies whether to ignore per-user .rhosts and .shosts files during HostbasedAuthentication. The system-wide /etc/hosts.equiv and /etc/shosts.equiv are still used regardless of this setting. Accepted values are yes (the default) to ignore all per-user files, shosts-only to allow the use of .shosts but to ignore .rhosts or no to allow both .shosts and rhosts. IgnoreUserKnownHosts Specifies whether sshd(8) should ignore the user's ~/.ssh/known_hosts during HostbasedAuthentication and use only the system-wide known hosts file /etc/ssh/ssh_known_hosts. The default is M-bM-^@M-^\noM-bM-^@M-^]. Include Include the specified configuration file(s). Multiple pathnames may be specified and each pathname may contain glob(7) wildcards that will be expanded and processed in lexical order. Files without absolute paths are assumed to be in /etc/ssh. An Include directive may appear inside a Match block to perform conditional inclusion. IPQoS Specifies the IPv4 type-of-service or DSCP class for the connection. Accepted values are af11, af12, af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, cs0, cs1, cs2, cs3, cs4, cs5, cs6, cs7, ef, le, lowdelay, throughput, reliability, a numeric value, or none to use the operating system default. This option may take one or two arguments, separated by whitespace. If one argument is specified, it is used as the packet class unconditionally. If two values are specified, the first is automatically selected for interactive sessions and the second for non-interactive sessions. The default is af21 (Low-Latency Data) for interactive sessions and cs1 (Lower Effort) for non- interactive sessions. KbdInteractiveAuthentication Specifies whether to allow keyboard-interactive authentication. All authentication styles from login.conf(5) are supported. The default is yes. The argument to this keyword must be yes or no. ChallengeResponseAuthentication is a deprecated alias for this. KerberosAuthentication Specifies whether the password provided by the user for PasswordAuthentication will be validated through the Kerberos KDC. To use this option, the server needs a Kerberos servtab which allows the verification of the KDC's identity. The default is no. KerberosGetAFSToken If AFS is active and the user has a Kerberos 5 TGT, attempt to acquire an AFS token before accessing the user's home directory. The default is no. KerberosOrLocalPasswd If password authentication through Kerberos fails then the password will be validated via any additional local mechanism such as /etc/passwd. The default is yes. KerberosTicketCleanup Specifies whether to automatically destroy the user's ticket cache file on logout. The default is yes. KexAlgorithms Specifies the permitted KEX (Key Exchange) algorithms that the server will offer to clients. The ordering of this list is not important, as the client specifies the preference order. Multiple algorithms must be comma-separated. If the specified list begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified algorithms will be appended to the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified algorithms (including wildcards) will be removed from the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X^M-bM-^@M-^Y character, then the specified algorithms will be placed at the head of the default set. The supported algorithms are: curve25519-sha256 curve25519-sha256@libssh.org diffie-hellman-group1-sha1 diffie-hellman-group14-sha1 diffie-hellman-group14-sha256 diffie-hellman-group16-sha512 diffie-hellman-group18-sha512 diffie-hellman-group-exchange-sha1 diffie-hellman-group-exchange-sha256 ecdh-sha2-nistp256 ecdh-sha2-nistp384 ecdh-sha2-nistp521 mlkem768x25519-sha256 sntrup761x25519-sha512 sntrup761x25519-sha512@openssh.com The default is: sntrup761x25519-sha512,sntrup761x25519-sha512@openssh.com, mlkem768x25519-sha256, curve25519-sha256,curve25519-sha256@libssh.org, ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521, diffie-hellman-group-exchange-sha256, diffie-hellman-group16-sha512,diffie-hellman-group18-sha512, diffie-hellman-group14-sha256 The list of supported key exchange algorithms may also be obtained using "ssh -Q KexAlgorithms". ListenAddress Specifies the local addresses sshd(8) should listen on. The following forms may be used: ListenAddress hostname|address [rdomain domain] ListenAddress hostname:port [rdomain domain] ListenAddress IPv4_address:port [rdomain domain] ListenAddress [hostname|address]:port [rdomain domain] The optional rdomain qualifier requests sshd(8) listen in an explicit routing domain. If port is not specified, sshd will listen on the address and all Port options specified. The default is to listen on all local addresses on the current default routing domain. Multiple ListenAddress options are permitted. For more information on routing domains, see rdomain(4). LoginGraceTime The server disconnects after this time if the user has not successfully logged in. If the value is 0, there is no time limit. The default is 120 seconds. LogLevel Gives the verbosity level that is used when logging messages from sshd(8). The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1, DEBUG2, and DEBUG3. The default is INFO. DEBUG and DEBUG1 are equivalent. DEBUG2 and DEBUG3 each specify higher levels of debugging output. Logging with a DEBUG level violates the privacy of users and is not recommended. LogVerbose Specify one or more overrides to LogLevel. An override consists of one or more pattern lists that matches the source file, function and line number to force detailed logging for. For example, an override pattern of: kex.c:*:1000,*:kex_exchange_identification():*,packet.c:* would enable detailed logging for line 1000 of kex.c, everything in the kex_exchange_identification() function, and all code in the packet.c file. This option is intended for debugging and no overrides are enabled by default. MACs Specifies the available MAC (message authentication code) algorithms. The MAC algorithm is used for data integrity protection. Multiple algorithms must be comma-separated. If the specified list begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified algorithms will be appended to the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified algorithms (including wildcards) will be removed from the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X^M-bM-^@M-^Y character, then the specified algorithms will be placed at the head of the default set. The algorithms that contain "-etm" calculate the MAC after encryption (encrypt-then-mac). These are considered safer and their use recommended. The supported MACs are: hmac-md5 hmac-md5-96 hmac-sha1 hmac-sha1-96 hmac-sha2-256 hmac-sha2-512 umac-64@openssh.com umac-128@openssh.com hmac-md5-etm@openssh.com hmac-md5-96-etm@openssh.com hmac-sha1-etm@openssh.com hmac-sha1-96-etm@openssh.com hmac-sha2-256-etm@openssh.com hmac-sha2-512-etm@openssh.com umac-64-etm@openssh.com umac-128-etm@openssh.com The default is: umac-64-etm@openssh.com,umac-128-etm@openssh.com, hmac-sha2-256-etm@openssh.com,hmac-sha2-512-etm@openssh.com, hmac-sha1-etm@openssh.com, umac-64@openssh.com,umac-128@openssh.com, hmac-sha2-256,hmac-sha2-512,hmac-sha1 The list of available MAC algorithms may also be obtained using "ssh -Q mac". Match Introduces a conditional block. If all of the criteria on the Match line are satisfied, the keywords on the following lines override those set in the global section of the config file, until either another Match line or the end of the file. If a keyword appears in multiple Match blocks that are satisfied, only the first instance of the keyword is applied. The arguments to Match are one or more criteria-pattern pairs or one of the single token criteria: All, which matches all criteria, or Invalid-User, which matches when the requested user- name does not match any known account. The available criteria are User, Group, Host, LocalAddress, LocalPort, RDomain, and Address (with RDomain representing the rdomain(4) on which the connection was received). The match patterns may consist of single entries or comma- separated lists and may use the wildcard and negation operators described in the PATTERNS section of ssh_config(5). The patterns in an Address criteria may additionally contain addresses to match in CIDR address/masklen format, such as 192.0.2.0/24 or 2001:db8::/32. Note that the mask length provided must be consistent with the address - it is an error to specify a mask length that is too long for the address or one with bits set in this host portion of the address. For example, 192.0.2.0/33 and 192.0.2.0/8, respectively. Only a subset of keywords may be used on the lines following a Match keyword. Available keywords are AcceptEnv, AllowAgentForwarding, AllowGroups, AllowStreamLocalForwarding, AllowTcpForwarding, AllowUsers, AuthenticationMethods, AuthorizedKeysCommand, AuthorizedKeysCommandUser, AuthorizedKeysFile, AuthorizedPrincipalsCommand, AuthorizedPrincipalsCommandUser, AuthorizedPrincipalsFile, Banner, CASignatureAlgorithms, ChannelTimeout, ChrootDirectory, ClientAliveCountMax, ClientAliveInterval, DenyGroups, DenyUsers, DisableForwarding, ExposeAuthInfo, ForceCommand, GatewayPorts, GSSAPIAuthentication, HostbasedAcceptedAlgorithms, HostbasedAuthentication, HostbasedUsesNameFromPacketOnly, IgnoreRhosts, Include, IPQoS, KbdInteractiveAuthentication, KerberosAuthentication, LogLevel, MaxAuthTries, MaxSessions, PAMServiceName, PasswordAuthentication, PermitEmptyPasswords, PermitListen, PermitOpen, PermitRootLogin, PermitTTY, PermitTunnel, PermitUserRC, PubkeyAcceptedAlgorithms, PubkeyAuthentication, PubkeyAuthOptions, RefuseConnection, RekeyLimit, RevokedKeys, RDomain, SetEnv, StreamLocalBindMask, StreamLocalBindUnlink, TrustedUserCAKeys, UnusedConnectionTimeout, X11DisplayOffset, X11Forwarding and X11UseLocalhost. MaxAuthTries Specifies the maximum number of authentication attempts permitted per connection. Once the number of failures reaches half this value, additional failures are logged. The default is 6. MaxSessions Specifies the maximum number of open shell, login or subsystem (e.g. sftp) sessions permitted per network connection. Multiple sessions may be established by clients that support connection multiplexing. Setting MaxSessions to 1 will effectively disable session multiplexing, whereas setting it to 0 will prevent all shell, login and subsystem sessions while still permitting forwarding. The default is 10. MaxStartups Specifies the maximum number of concurrent unauthenticated connections to the SSH daemon. Additional connections will be dropped until authentication succeeds or the LoginGraceTime expires for a connection. The default is 10:30:100. Alternatively, random early drop can be enabled by specifying the three colon separated values start:rate:full (e.g. "10:30:60"). sshd(8) will refuse connection attempts with a probability of rate/100 (30%) if there are currently start (10) unauthenticated connections. The probability increases linearly and all connection attempts are refused if the number of unauthenticated connections reaches full (60). ModuliFile Specifies the moduli(5) file that contains the Diffie-Hellman groups used for the M-bM-^@M-^\diffie-hellman-group-exchange-sha1M-bM-^@M-^] and M-bM-^@M-^\diffie-hellman-group-exchange-sha256M-bM-^@M-^] key exchange methods. The default is /etc/moduli. PAMServiceName Specifies the service name used for Pluggable Authentication Modules (PAM) authentication, authorisation and session controls when UsePAM is enabled. The default is sshd. PasswordAuthentication Specifies whether password authentication is allowed. The default is yes. PermitEmptyPasswords When password authentication is allowed, it specifies whether the server allows login to accounts with empty password strings. The default is no. PermitListen Specifies the addresses/ports on which a remote TCP port forwarding may listen. The listen specification must be one of the following forms: PermitListen port PermitListen host:port Multiple permissions may be specified by separating them with whitespace. An argument of any can be used to remove all restrictions and permit any listen requests. An argument of none can be used to prohibit all listen requests. The host name may contain wildcards as described in the PATTERNS section in ssh_config(5). The wildcard M-bM-^@M-^X*M-bM-^@M-^Y can also be used in place of a port number to allow all ports. By default all port forwarding listen requests are permitted. Note that the GatewayPorts option may further restrict which addresses may be listened on. Note also that ssh(1) will request a listen host of M-bM-^@M-^\localhostM-bM-^@M-^] if no listen host was specifically requested, and this name is treated differently to explicit localhost addresses of M-bM-^@M-^\127.0.0.1M-bM-^@M-^] and M-bM-^@M-^\::1M-bM-^@M-^]. PermitOpen Specifies the destinations to which TCP port forwarding is permitted. The forwarding specification must be one of the following forms: PermitOpen host:port PermitOpen IPv4_addr:port PermitOpen [IPv6_addr]:port Multiple forwards may be specified by separating them with whitespace. An argument of any can be used to remove all restrictions and permit any forwarding requests. An argument of none can be used to prohibit all forwarding requests. The wildcard M-bM-^@M-^X*M-bM-^@M-^Y can be used for host or port to allow all hosts or ports respectively. Otherwise, no pattern matching or address lookups are performed on supplied names. By default all port forwarding requests are permitted. PermitRootLogin Specifies whether root can log in using ssh(1). The argument must be yes, prohibit-password, forced-commands-only, or no. The default is prohibit-password. If this option is set to prohibit-password (or its deprecated alias, without-password), password and keyboard-interactive authentication are disabled for root. If this option is set to forced-commands-only, root login with public key authentication will be allowed, but only if the command option has been specified (which may be useful for taking remote backups even if root login is normally not allowed). All other authentication methods are disabled for root. If this option is set to no, root is not allowed to log in. PermitTTY Specifies whether pty(4) allocation is permitted. The default is yes. PermitTunnel Specifies whether tun(4) device forwarding is allowed. The argument must be yes, point-to-point (layer 3), ethernet (layer 2), or no. Specifying yes permits both point-to-point and ethernet. The default is no. Independent of this setting, the permissions of the selected tun(4) device must allow access to the user. PermitUserEnvironment Specifies whether ~/.ssh/environment and environment= options in ~/.ssh/authorized_keys are processed by sshd(8). Valid options are yes, no or a pattern-list specifying which environment variable names to accept (for example "LANG,LC_*"). The default is no. Enabling environment processing may enable users to bypass access restrictions in some configurations using mechanisms such as LD_PRELOAD. PermitUserRC Specifies whether any ~/.ssh/rc file is executed. The default is yes. PerSourceMaxStartups Specifies the number of unauthenticated connections allowed from a given source address, or M-bM-^@M-^\noneM-bM-^@M-^] if there is no limit. This limit is applied in addition to MaxStartups, whichever is lower. The default is none. PerSourceNetBlockSize Specifies the number of bits of source address that are grouped together for the purposes of applying PerSourceMaxStartups limits. Values for IPv4 and optionally IPv6 may be specified, separated by a colon. The default is 32:128, which means each address is considered individually. PerSourcePenalties Controls penalties for various conditions that may represent attacks on sshd(8). If a penalty is enforced against a client then its source address and any others in the same network, as defined by PerSourceNetBlockSize, will be refused connection for a period. A penalty doesn't affect concurrent connections in progress, but multiple penalties from the same source from concurrent connections will accumulate up to a maximum. Conversely, penalties are not applied until a minimum threshold time has been accumulated. Penalties are enabled by default with the default settings listed below but may disabled using the no keyword. The defaults may be overridden by specifying one or more of the keywords below, separated by whitespace. All keywords accept arguments, e.g. "crash:2m". crash:duration Specifies how long to refuse clients that cause a crash of sshd(8) (default: 90s). authfail:duration Specifies how long to refuse clients that disconnect after making one or more unsuccessful authentication attempts (default: 5s). refuseconnection:duration Specifies how long to refuse clients that were administratively prohibited connection via the RefuseConnection option (default: 10s). noauth:duration Specifies how long to refuse clients that disconnect without attempting authentication (default: 1s). This timeout should be used cautiously otherwise it may penalise legitimate scanning tools such as ssh-keyscan(1). grace-exceeded:duration Specifies how long to refuse clients that fail to authenticate after LoginGraceTime (default: 10s). max:duration Specifies the maximum time a particular source address range will be refused access for (default: 10m). Repeated penalties will accumulate up to this maximum. min:duration Specifies the minimum penalty that must accrue before enforcement begins (default: 15s). max-sources4:number, max-sources6:number Specifies the maximum number of client IPv4 and IPv6 address ranges to track for penalties (default: 65536 for both). overflow:mode Controls how the server behaves when max-sources4 or max-sources6 is exceeded. There are two operating modes: deny-all, which denies all incoming connections other than those exempted via PerSourcePenaltyExemptList until a penalty expires, and permissive, which allows new connections by removing existing penalties early (default: permissive). Note that client penalties below the min threshold count against the total number of tracked penalties. IPv4 and IPv6 addresses are tracked separately, so an overflow in one will not affect the other. overflow6:mode Allows specifying a different overflow mode for IPv6 addresses. The default it to use the same overflow mode as was specified for IPv4. PerSourcePenaltyExemptList Specifies a comma-separated list of addresses to exempt from penalties. This list may contain wildcards and CIDR address/masklen ranges. Note that the mask length provided must be consistent with the address - it is an error to specify a mask length that is too long for the address or one with bits set in this host portion of the address. For example, 192.0.2.0/33 and 192.0.2.0/8, respectively. The default is not to exempt any addresses. PidFile Specifies the file that contains the process ID of the SSH daemon, or none to not write one. The default is /var/run/sshd.pid. Port Specifies the port number that sshd(8) listens on. The default is 22. Multiple options of this type are permitted. See also ListenAddress. PrintLastLog Specifies whether sshd(8) should print the date and time of the last user login when a user logs in interactively. The default is yes. PrintMotd Specifies whether sshd(8) should print /etc/motd when a user logs in interactively. (On some systems it is also printed by the shell, /etc/profile, or equivalent.) The default is yes. PubkeyAcceptedAlgorithms Specifies the signature algorithms that will be accepted for public key authentication as a list of comma-separated patterns. Alternately if the specified list begins with a M-bM-^@M-^X+M-bM-^@M-^Y character, then the specified algorithms will be appended to the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X-M-bM-^@M-^Y character, then the specified algorithms (including wildcards) will be removed from the default set instead of replacing them. If the specified list begins with a M-bM-^@M-^X^M-bM-^@M-^Y character, then the specified algorithms will be placed at the head of the default set. The default for this option is: ssh-ed25519-cert-v01@openssh.com, ecdsa-sha2-nistp256-cert-v01@openssh.com, ecdsa-sha2-nistp384-cert-v01@openssh.com, ecdsa-sha2-nistp521-cert-v01@openssh.com, sk-ssh-ed25519-cert-v01@openssh.com, sk-ecdsa-sha2-nistp256-cert-v01@openssh.com, rsa-sha2-512-cert-v01@openssh.com, rsa-sha2-256-cert-v01@openssh.com, ssh-ed25519, ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521, sk-ssh-ed25519@openssh.com, sk-ecdsa-sha2-nistp256@openssh.com, rsa-sha2-512,rsa-sha2-256 The list of available signature algorithms may also be obtained using "ssh -Q PubkeyAcceptedAlgorithms". PubkeyAuthOptions Sets one or more public key authentication options. The supported keywords are: none (the default; indicating no additional options are enabled), touch-required and verify-required. The touch-required option causes public key authentication using a FIDO authenticator algorithm (i.e. ecdsa-sk or ed25519-sk) to always require the signature to attest that a physically present user explicitly confirmed the authentication (usually by touching the authenticator). By default, sshd(8) requires user presence unless overridden with an authorized_keys option. The touch-required flag disables this override. The verify-required option requires a FIDO key signature attest that the user was verified, e.g. via a PIN. Neither the touch-required or verify-required options have any effect for other, non-FIDO, public key types. PubkeyAuthentication Specifies whether public key authentication is allowed. The default is yes. RefuseConnection Indicates that sshd(8) should unconditionally terminate the connection. Additionally, a refuseconnection penalty may be recorded against the source of the connection if PerSourcePenalties are enabled. This option is only really useful in a Match block. RekeyLimit Specifies the maximum amount of data that may be transmitted or received before the session key is renegotiated, optionally followed by a maximum amount of time that may pass before the session key is renegotiated. The first argument is specified in bytes and may have a suffix of M-bM-^@M-^XKM-bM-^@M-^Y, M-bM-^@M-^XMM-bM-^@M-^Y, or M-bM-^@M-^XGM-bM-^@M-^Y to indicate Kilobytes, Megabytes, or Gigabytes, respectively. The default is between M-bM-^@M-^X1GM-bM-^@M-^Y and M-bM-^@M-^X4GM-bM-^@M-^Y, depending on the cipher. The optional second value is specified in seconds and may use any of the units documented in the TIME FORMATS section. The default value for RekeyLimit is default none, which means that rekeying is performed after the cipher's default amount of data has been sent or received and no time based rekeying is done. RequiredRSASize Specifies the minimum RSA key size (in bits) that sshd(8) will accept. User and host-based authentication keys smaller than this limit will be refused. The default is 1024 bits. Note that this limit may only be raised from the default. RevokedKeys Specifies revoked public keys file, or none to not use one. Keys listed in this file will be refused for public key authentication. Note that if this file is not readable, then public key authentication will be refused for all users. Keys may be specified as a text file, listing one public key per line, or as an OpenSSH Key Revocation List (KRL) as generated by ssh-keygen(1). For more information on KRLs, see the KEY REVOCATION LISTS section in ssh-keygen(1). RDomain Specifies an explicit routing domain that is applied after authentication has completed. The user session, as well as any forwarded or listening IP sockets, will be bound to this rdomain(4). If the routing domain is set to %D, then the domain in which the incoming connection was received will be applied. SecurityKeyProvider Specifies a path to a library that will be used when loading FIDO authenticator-hosted keys, overriding the default of using the built-in USB HID support. SetEnv Specifies one or more environment variables to set in child sessions started by sshd(8) as M-bM-^@M-^\NAME=VALUEM-bM-^@M-^]. The environment value may be quoted (e.g. if it contains whitespace characters). Environment variables set by SetEnv override the default environment and any variables specified by the user via AcceptEnv or PermitUserEnvironment. SshdSessionPath Overrides the default path to the sshd-session binary that is invoked to handle each connection. The default is /usr/libexec/sshd-session. This option is intended for use by tests. StreamLocalBindMask Sets the octal file creation mode mask (umask) used when creating a Unix-domain socket file for local or remote port forwarding. This option is only used for port forwarding to a Unix-domain socket file. The default value is 0177, which creates a Unix-domain socket file that is readable and writable only by the owner. Note that not all operating systems honor the file mode on Unix-domain socket files. StreamLocalBindUnlink Specifies whether to remove an existing Unix-domain socket file for local or remote port forwarding before creating a new one. If the socket file already exists and StreamLocalBindUnlink is not enabled, sshd will be unable to forward the port to the Unix- domain socket file. This option is only used for port forwarding to a Unix-domain socket file. The argument must be yes or no. The default is no. StrictModes Specifies whether sshd(8) should check file modes and ownership of the user's files and home directory before accepting login. This is normally desirable because novices sometimes accidentally leave their directory or files world-writable. The default is yes. Note that this does not apply to ChrootDirectory, whose permissions and ownership are checked unconditionally. Subsystem Configures an external subsystem (e.g. file transfer daemon). Arguments should be a subsystem name and a command (with optional arguments) to execute upon subsystem request. The command sftp-server implements the SFTP file transfer subsystem. Alternately the name internal-sftp implements an in-process SFTP server. This may simplify configurations using ChrootDirectory to force a different filesystem root on clients. It accepts the same command line arguments as sftp-server and even though it is in-process, settings such as LogLevel or SyslogFacility do not apply to it and must be set explicitly via command line arguments. By default no subsystems are defined. SyslogFacility Gives the facility code that is used when logging messages from sshd(8). The possible values are: DAEMON, USER, AUTH, LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7. The default is AUTH. TCPKeepAlive Specifies whether the system should send TCP keepalive messages to the other side. If they are sent, death of the connection or crash of one of the machines will be properly noticed. However, this means that connections will die if the route is down temporarily, and some people find it annoying. On the other hand, if TCP keepalives are not sent, sessions may hang indefinitely on the server, leaving "ghost" users and consuming server resources. The default is yes (to send TCP keepalive messages), and the server will notice if the network goes down or the client host crashes. This avoids infinitely hanging sessions. To disable TCP keepalive messages, the value should be set to no. TrustedUserCAKeys Specifies a file containing public keys of certificate authorities that are trusted to sign user certificates for authentication, or none to not use one. Keys are listed one per line; empty lines and comments starting with M-bM-^@M-^X#M-bM-^@M-^Y are allowed. If a certificate is presented for authentication and has its signing CA key listed in this file, then it may be used for authentication for any user listed in the certificate's principals list. Note that certificates that lack a list of principals will not be permitted for authentication using TrustedUserCAKeys. For more details on certificates, see the CERTIFICATES section in ssh-keygen(1). UnusedConnectionTimeout Specifies whether and how quickly sshd(8) should close client connections with no open channels. Open channels include active shell, command execution or subsystem sessions, connected network, socket, agent or X11 forwardings. Forwarding listeners, such as those from the ssh(1) -R flag, are not considered as open channels and do not prevent the timeout. The timeout value is specified in seconds or may use any of the units documented in the TIME FORMATS section. Note that this timeout starts when the client connection completes user authentication but before the client has an opportunity to open any channels. Caution should be used when using short timeout values, as they may not provide sufficient time for the client to request and open its channels before terminating the connection. The default none is to never expire connections for having no open channels. This option may be useful in conjunction with ChannelTimeout. UseDNS Specifies whether sshd(8) should look up the remote host name, and to check that the resolved host name for the remote IP address maps back to the very same IP address. If this option is set to no (the default) then only addresses and not host names may be used in ~/.ssh/authorized_keys from and sshd_config Match Host directives. UsePAM Enables the Pluggable Authentication Module interface. If set to yes this will enable PAM authentication using KbdInteractiveAuthentication and PasswordAuthentication in addition to PAM account and session module processing for all authentication types. Because PAM keyboard-interactive authentication usually serves an equivalent role to password authentication, you should disable either PasswordAuthentication or KbdInteractiveAuthentication. If UsePAM is enabled, you will not be able to run sshd(8) as a non-root user. The default is no. VersionAddendum Optionally specifies additional text to append to the SSH protocol banner sent by the server upon connection. The default is none. X11DisplayOffset Specifies the first display number available for sshd(8)'s X11 forwarding. This prevents sshd from interfering with real X11 servers. The default is 10. X11Forwarding Specifies whether X11 forwarding is permitted. The argument must be yes or no. The default is no. When X11 forwarding is enabled, there may be additional exposure to the server and to client displays if the sshd(8) proxy display is configured to listen on the wildcard address (see X11UseLocalhost), though this is not the default. Additionally, the authentication spoofing and authentication data verification and substitution occur on the client side. The security risk of using X11 forwarding is that the client's X11 display server may be exposed to attack when the SSH client requests forwarding (see the warnings for ForwardX11 in ssh_config(5)). A system administrator may have a stance in which they want to protect clients that may expose themselves to attack by unwittingly requesting X11 forwarding, which can warrant a no setting. Note that disabling X11 forwarding does not prevent users from forwarding X11 traffic, as users can always install their own forwarders. X11UseLocalhost Specifies whether sshd(8) should bind the X11 forwarding server to the loopback address or to the wildcard address. By default, sshd binds the forwarding server to the loopback address and sets the hostname part of the DISPLAY environment variable to localhost. This prevents remote hosts from connecting to the proxy display. However, some older X11 clients may not function with this configuration. X11UseLocalhost may be set to no to specify that the forwarding server should be bound to the wildcard address. The argument must be yes or no. The default is yes. XAuthLocation Specifies the full pathname of the xauth(1) program, or none to not use one. The default is /usr/X11R6/bin/xauth. TIME FORMATS sshd(8) command-line arguments and configuration file options that specify time may be expressed using a sequence of the form: time[qualifier], where time is a positive integer value and qualifier is one of the following: M-bM-^_M-(noneM-bM-^_M-) seconds s | S seconds m | M minutes h | H hours d | D days w | W weeks Each member of the sequence is added together to calculate the total time value. Time format examples: 600 600 seconds (10 minutes) 10m 10 minutes 1h30m 1 hour 30 minutes (90 minutes) TOKENS Arguments to some keywords can make use of tokens, which are expanded at runtime: %% A literal M-bM-^@M-^X%M-bM-^@M-^Y. %C Identifies the connection endpoints, containing four space- separated values: client address, client port number, server address, and server port number. %D The routing domain in which the incoming connection was received. %F The fingerprint of the CA key. %f The fingerprint of the key or certificate. %h The home directory of the user. %i The key ID in the certificate. %K The base64-encoded CA key. %k The base64-encoded key or certificate for authentication. %s The serial number of the certificate. %T The type of the CA key. %t The key or certificate type. %U The numeric user ID of the target user. %u The username. AuthorizedKeysCommand accepts the tokens %%, %C, %D, %f, %h, %k, %t, %U, and %u. AuthorizedKeysFile accepts the tokens %%, %h, %U, and %u. AuthorizedPrincipalsCommand accepts the tokens %%, %C, %D, %F, %f, %h, %i, %K, %k, %s, %T, %t, %U, and %u. AuthorizedPrincipalsFile accepts the tokens %%, %h, %U, and %u. ChrootDirectory accepts the tokens %%, %h, %U, and %u. RoutingDomain accepts the token %D. FILES /etc/ssh/sshd_config Contains configuration data for sshd(8). This file should be writable by root only, but it is recommended (though not necessary) that it be world-readable.
