- Although there never was a 3.0.3 release, the linux boys cleverly
"released" one in late 1995.
v3.0.2 Thu Apr 20 21:28:16 PDT 1995
- Change configuration to not use gcc v2 flags with gcc v1.
- Redo gmt2local() so that it works under BSDI (which seems to return
an empty timezone struct from gettimeofday()). Based on report from

v3.0 Mon Jun 20 19:23:27 PDT 1994
- Added support for printing tcp option timestamps thanks to
Mark Andrews (mandrews@alias.com).
- Reorganize protocol dumpers to take const pointers to packets so they
never change the contents (i.e., they used to do endian conversions
in place). Previously, whenever more than one pass was taken over
the packet, the packet contents would be dumped incorrectly (i.e.,
the output form -x would be wrong on little endian machines because
the protocol dumpers would modify the data). Thanks to Charles Hannum
(mycroft@gnu.ai.mit.edu) for reporting this problem.
- Added support for decnet protocol dumping thanks to Jeff Mogul
(mogul@pa.dec.com).
- Fix bug that caused length of packet to be incorrectly printed
(off by ether header size) for unknown ethernet types thanks
to Greg Miller (gmiller@kayak.mitre.org).

- print-arp.c: Print hardware ethernet addresses if they're not
what we expect.
- print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
- print-fddi.c: Improvements. Thanks to Jeffrey Mogul
(mogul@pa.dec.com).
- print-icmp.c: Byte swap netmask before printing. Thanks to
Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
- print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
By default, only the inner packet is dumped, appended with the token
"(encap)". Under -v, both the inner and output packets are dumped
(on the same line). Note that the filter applies to the original packet,
not the encapsulated packet. So if you run tcpdump on a net with an
IP Multicast tunnel, you cannot filter out the datagrams using the
conventional syntax. (You can filter away all the ip-in-ip traffic
with "not ip proto 4".)
- print-nfs.c: Keep pending rpc's in circular table. Add generic
nfs header and remove os dependences. Thanks to Jeffrey Mogul.
- print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
- tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
(sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
Add && and || operators
v2.2.1 Tue Jun 6 17:57:22 PDT 1992
- Fix bug with -c flag.
v2.2 Fri May 22 17:19:41 PDT 1992
- savefile.c: Remove hack that shouldn't have been exported. Add
truncate checks.
- Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
matches non-echo/reply ICMP packets.
- Many improvements to filter code optimizer.
- Added 'multicast' keyword and extended the 'broadcast' keyword can now be
so that protocol qualifications are allowed. For example, "ip broadcast"
and "ether multicast" are valid filters.
- Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
patches to netinet/if_loop.c.
- Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
- Added EGP and OSPF printers, thanks to Jeffrey Honig.

- Add truncation checks.
- inet.c: Support BSD style SIOCGIFCONF.
- nametoaddr.c: Handle multi addresses for single host.
- optimize.c: Rewritten.

stanonik@nprdc.navy.mil) Add missing printf() argument.
- print-bootp.c: First attempt at decoding the vendor buffer.
- print-domain.c: Fix truncation checks.
- print-icmp.c: Calculate length of packets from the ip header.
- print-ip.c: Print frag id in decimal (so it's easier to match up
with non-frags). Add support for ospf, egp and igmp.
- print-nfs.c: Lots of changes.
- print-ntp.c: Make some verbose output depend on -v.
- print-snmp.c: New version from John LoVerso.
- print-tcp.c: Print rfc1072 tcp options.
- tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
(microseconds) worth of precision. Fix uid bugs.
- A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
With this option, you can create an architecture independent binary
trace file in real time, without the overhead of the packet printer.
At a later time, the packets can be filtered (again) and printed.
- BSD is supported. You must have BPF in your kernel.
Since the filtering is now done in the kernel, fewer packets are
dropped. In fact, with BPF and the packet dumper option, a measly
Sun 3/50 can keep up with a busy network.
- Compressed SLIP packets can now be dumped, provided you use our
SLIP software and BPF. These packets are dumped as any other IP
packet; the compressed headers are dumped with the '-e' option.
- Machines with little-endian byte ordering are supported (thanks to
Jeff Mogul).
- Ultrix 4.0 is supported (also thanks to Jeff Mogul).
- IBM RT and Stanford Enetfilter support has been added by
- Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
+ Rayan Zachariassen <rayan@canet.ca>. tcpdump has been tested under
both the vanilla Enetfilter interface, and the extended interface
(#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
- TFTP packets are now printed (requests only).
- BOOTP packets are now printed.
- SNMP packets are now printed. (thanks to John LoVerso of Xylogics).

supported thanks to Steve McCanne and Craig Leres.
- SunOS 4 is now supported thanks to Micky Liu of Columbia
University (micky@cunixc.cc.columbia.edu).
- IP options are now printed.
- RIP packets are now printed.
- There's a -v flag that prints out more information than the
default (e.g., it will enable printing of IP ttl, tos and id)
and -q flag that prints out less (e.g., it will disable
interpretation of AppleTalk-in-UDP).
- The grammar has undergone substantial changes (if you have an
earlier version of tcpdump, you should re-read the manual
entry).
The most useful change is the addition of an expression
syntax that lets you filter on arbitrary fields or values in the
packet. E.g., "ip[0] > 0x45" would print only packets with IP
options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
packets.
The most painful change is that concatenation no longer means
"and" -- e.g., you have to say "host foo and port bar" instead
of "host foo port bar". The up side to this down is that
repeated qualifiers can be omitted, making most filter
expressions shorter. E.g., you can now say "ip host foo and
(bar or baz)" to look at ip traffic between hosts foo and bar or
between hosts foo and baz. [The old way of saying this was "ip
host foo and (ip host bar or ip host baz)".]

#
# OK, this is a pain.
#
# When building on NetBSD, with a libpcap installed from pkgsrc,
# a -Wl,-rpath,/usr/pkg/lib option is added to the options when
# linking tcpdump. This puts /usr/pkg/lib into the run-time path.
#
# However, by default, CMake adds a rule to the install CMake script
# a CMake command (using an undocumented subcommand of file()) that
# strips /usr/pkg/lib *out* of the run-time path; the message in the
# output for the "install" target is
#
# -- Set runtime path of "{target-directory}/tcpdump" to ""
#
# I am not certain what the rationale is for doing this, but a
# *consequence* of this is that, when you run the installed tcpdump,
# it fails to find libpcap.so:
#
# $ {target-directory}/tcpdump -h
# {target-directory}/tcpdump: Shared object "libpcap.so.0" not found
#
# It also appears to be the case that, on Ubuntu 22.04, FreeBSD 12,
# DragonFly BSD 5.8, OpenBSD 6.6, and Solaris 11.4,
#
# On Ubuntu and Solaris, even if you have a libpcap in /usr/local, you
# have to provide not only -I/usr/local/include and -L/usr/local/lib,
# you also must provide -Wl,-rpath,/usr/local/lib in order to have
# the run-time linker look in /usr/local/lib for libpcap. If it's not
# specified, then, if the shared library major version number of the
# libpcap in /usr/lib is the same as the shared major version number
# of the libpcap in /usr/local/lib, the run-time linker will find the
# libpcap in /usr/lib; if the versions are different, the run-time
# linker will fail to find the libpcap in /usr/lib, so the program will
# fail to run.
#
# We suppress this by setting CMAKE_INSTALL_RPATH_USE_LINK_PATH to TRUE;
# as the documentation for that variable says:
#
# Add paths to linker search and installed rpath.
#
# CMAKE_INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to True
# will append to the runtime search path (rpath) of installed
# binaries any directories outside the project that are in the linker
# search path or contain linked library files. The directories are
# appended after the value of the INSTALL_RPATH target property.
#
# If, for whatever reason, directories in which we search for external
# libraries, other than the standard system library directories, are
# added to the executable's rpath in the build process, we most
-# defintely want them in the installed image's rpath if they are
+# definitely want them in the installed image's rpath if they are
# necessary in order to find the libraries at run time.

-# OK, this is a royal pain.
+# We explicitly indicate what languages are used in tcpdump to avoid
+# checking for a C++ compiler.
+#
+# One reason to avoid that check is that there's no need to waste
+# configuration time performing it.
+#
+# Another reason is that:
#
# CMake will try to determine the sizes of some data types, including
# void *, early in the process of configuration; apparently, it's done
# as part of processing the project() command.
#
# At least as of CMake 2.8.6, it does so by checking the size of
# "void *" in C, setting CMAKE_C_SIZEOF_DATA_PTR based on that,
# setting CMAKE_SIZEOF_VOID_P to that, and then checking the size
# of "void *" in C++, setting CMAKE_CXX_SIZEOF_DATA_PTR based on
# that, and then setting CMAKE_SIZEOF_VOID_P to *that*.
#
# The compile tests include whatever C flags may have been provided
# to CMake in the CFLAGS and CXXFLAGS environment variables.
#
# If you set an architecture flag such as -m32 or -m64 in CFLAGS
# but *not* in CXXFLAGS, the size for C++ will win, and hilarity
# will ensue.
#
# Or if, at least on Solaris, you have a newer version of GCC
# installed, but *not* a newer version of G++, and you have Oracle
# Studio installed, it will find GCC, which will default to building
# 64-bit, and Oracle Studio's C++ compiler, which will default to
# building 32-bit, the size for C++ will win, and, again, hilarity
# will ensue.

-# C++ code in tcpdump.

# Some Information for Contributors
Thank you for considering to make a contribution to tcpdump! Please use the
guidelines below to achieve the best results and experience for everyone.
## How to report bugs and other problems
**To report a security issue (segfault, buffer overflow, infinite loop, arbitrary
code execution etc) please send an e-mail to security@tcpdump.org, do not use
the bug tracker!**
To report a non-security problem (failure to compile, incorrect output in the
protocol printout, missing support for a particular protocol etc) please check
first that it reproduces with the latest stable release of tcpdump and the latest
stable release of libpcap. If it does, please check that the problem reproduces
with the current git master branch of tcpdump and the current git master branch of
libpcap. If it does (and it is not a security-related problem, otherwise see
above), please navigate to the
[bug tracker](https://github.com/the-tcpdump-group/tcpdump/issues)
and check if the problem has already been reported. If it has not, please open
a new issue and provide the following details:
* tcpdump and libpcap version (`tcpdump --version`)
* operating system name and version and any other details that may be relevant
(`uname -a`, compiler name and version, CPU type etc.)
* custom `configure`/`cmake` flags, if any
* statement of the problem
* steps to reproduce
Please note that if you know exactly how to solve the problem and the solution
would not be too intrusive, it would be best to contribute some development time
and to open a pull request instead as discussed below.
Still not sure how to do? Feel free to
[subscribe to the mailing list](https://www.tcpdump.org/#mailing-lists)
and ask!

Currently, the effect is
* add (via `configure`, in `Makefile`) some warnings options (`-Wall`,
`-Wmissing-prototypes`, `-Wstrict-prototypes`, ...) to the compiler if it
supports these options,

+6) Configure and build

-6) Add/update tests
+7) Add/update tests
The `tests` directory contains regression tests of the dissection of captured
packets. Those captured packets were saved running tcpdump with option
`-w sample.pcap`. Additional options, such as `-n`, are used to create relevant
and reproducible output; `-#` is used to indicate which particular packets
have output that differs. The tests are run with the `TZ` environment
variable set to `GMT0`, so that UTC, rather than the local time where the
tests are being run, is used when "local time" values are printed. The
actual test compares the current text output with the expected result
(`sample.out`) saved from a previous version.
Any new/updated fields in a dissector must be present in a `sample.pcap` file
and the corresponding output file.
Configuration is set in `tests/TESTLIST`.
Each line in this file has the following format:
```
test-name sample.pcap sample.out tcpdump-options
```
The `sample.out` file can be produced as follows:
```
(cd tests && TZ=GMT0 ../tcpdump -# -n -r sample.pcap tcpdump-options > sample.out)
```
Or, for convenience, use `./update-test.sh test-name`
It is often useful to have test outputs with different verbosity levels
(none, `-v`, `-vv`, `-vvv`, etc.) depending on the code.
-7) Test using `make check` (current build options) and `./build_matrix.sh`

## Code style and generic remarks

+1) A thorough reading of some other printers code is useful.
-* Put the normative reference if any as comments (RFC, etc.).
+2) To help learn how tcpdump works or to help debugging:
+ You can configure and build tcpdump with the instrumentation of functions:
+ ```
+ $ ./configure --enable-instrument-functions
+ $ make -s clean all
+ ```
+
+ This generates instrumentation calls for entry and exit to functions.
+ Just after function entry and just before function exit, these
+ profiling functions are called and print the function names with
+ indentation and call level.
+
+ If entering in a function, it prints also the calling function name with
+ file name and line number. There may be a small shift in the line number.
+
+ In some cases, with Clang 11, the file number is unknown (printed '??')
+ or the line number is unknown (printed '?'). In this case, use GCC.
+
+ If the environment variable INSTRUMENT is
+ - unset or set to an empty string, print nothing, like with no
+ instrumentation
+ - set to "all" or "a", print all the functions names
+ - set to "global" or "g", print only the global functions names
+
+ This allows to run:
+ ```
+ $ INSTRUMENT=a ./tcpdump ...
+ $ INSTRUMENT=g ./tcpdump ...
+ $ INSTRUMENT= ./tcpdump ...
+ ```
+ or
+ ```
+ $ export INSTRUMENT=global
+ $ ./tcpdump ...
+ ```
+
+ The library libbfd is used, therefore the binutils-dev package is required.

+3) Put the normative reference if any as comments (RFC, etc.).
+
+4) Put the format of packets/headers/options as comments if there is no
published normative reference.
-* The printer may receive incomplete packet in the buffer, truncated at any
+5) The printer may receive incomplete packet in the buffer, truncated at any
random position, for example by capturing with `-s size` option.
+ This means that an attempt to fetch packet data based on the expected
+ format of the packet may run the risk of overrunning the buffer.
+
+ Furthermore, if the packet is complete, but is not correctly formed,
+ that can also cause a printer to overrun the buffer, as it will be
+ fetching packet data based on the expected format of the packet.
+
+ Therefore, integral, IPv4 address, and octet sequence values should
+ be fetched using the `GET_*()` macros, which are defined in
+ `extract.h`.
+
If your code reads and decodes every byte of the protocol packet, then to
ensure proper and complete bounds checks it would be sufficient to read all
- packet data using the `GET_*()` macros, typically:
- ```
- GET_U_1(p)
- GET_S_1(p)
- GET_BE_U_n(p), n in { 2, 3, 4, 5, 6, 7, 8 }
- GET_BE_S_n(p), n in { 2, 3, 4, 5, 6, 7, 8 }
- ```
+ packet data using the `GET_*()` macros.
+
If your code uses the macros above only on some packet data, then the gaps
would have to be bounds-checked using the `ND_TCHECK_*()` macros:
```
ND_TCHECK_n(p), n in { 1, 2, 3, 4, 5, 6, 7, 8, 16 }
ND_TCHECK_SIZE(p)
ND_TCHECK_LEN(p, l)
```
- For the `ND_TCHECK_*` macros (if not already done):
+
+ where *p* points to the data not being decoded. For `ND_CHECK_n()`,
+ *n* is the length of the gap, in bytes. For `ND_CHECK_SIZE()`, the
+ length of the gap, in bytes, is the size of an item of the data type
+ to which *p* points. For `ND_CHECK_LEN()`, *l* is the length of the
+ gap, in bytes.
+
+ For the `GET_*()` and `ND_TCHECK_*` macros (if not already done):
* Assign: `ndo->ndo_protocol = "protocol";`
* Define: `ND_LONGJMP_FROM_TCHECK` before including `netdissect.h`
* Make sure that the intersection of `GET_*()` and `ND_TCHECK_*()` is minimal,
but at the same time their union covers all packet data in all cases.
You can test the code via:
```
sudo ./tcpdump -s snaplen [-v][v][...] -i lo # in a terminal
sudo tcpreplay -i lo sample.pcap # in another terminal
```
You should try several values for snaplen to do various truncation.
-* Do invalid packet checks in code: Think that your code can receive in input
+* The `GET_*()` macros that fetch integral values are:
+ ```
+ GET_U_1(p)
+ GET_S_1(p)
+ GET_BE_U_n(p), n in { 2, 3, 4, 5, 6, 7, 8 }
+ GET_BE_S_n(p), n in { 2, 3, 4, 5, 6, 7, 8 }
+ GET_LE_U_n(p), n in { 2, 3, 4, 5, 6, 7, 8 }
+ GET_LE_S_n(p), n in { 2, 3, 4, 5, 6, 7, 8 }
+ ```
+
+ where *p* points to the integral value in the packet buffer. The
+ macro returns the integral value at that location.
+
+ `U` indicates that an unsigned value is fetched; `S` indicates that a
+ signed value is fetched. For multi-byte values, `BE` indicates that
+ a big-endian value ("network byte order") is fetched, and `LE`
+ indicates that a little-endian value is fetched. *n* is the length,
+ in bytes, of the multi-byte integral value to be fetched.
+
+ In addition to the bounds checking the `GET_*()` macros perform,
+ using those macros has other advantages:
+
+ * tcpdump runs on both big-endian and little-endian systems, so
+ fetches of multi-byte integral values must be done in a fashion
+ that works regardless of the byte order of the machine running
+ tcpdump. The `GET_BE_*()` macros will fetch a big-endian value and
+ return a host-byte-order value on both big-endian and little-endian
+ machines, and the `GET_LE_*()` macros will fetch a little-endian
+ value and return a host-byte-order value on both big-endian and
+ little-endian machines.
+
+ * tcpdump runs on machines that do not support unaligned access to
+ multi-byte values, and packet values are not guaranteed to be
+ aligned on the proper boundary. The `GET_BE_*()` and `GET_LE_*()`
+ macros will fetch values even if they are not aligned on the proper
+ boundary.
+
+* The `GET_*()` macros that fetch IPv4 address values are:
+ ```
+ GET_IPV4_TO_HOST_ORDER(p)
+ GET_IPV4_TO_NETWORK_ORDER(p)
+ ```
+
+ where *p* points to the address in the packet buffer.
+ `GET_IPV4_TO_HOST_ORDER()` returns the address in the byte order of
+ the host that is running tcpdump; `GET_IPV4_TO_NETWORK_ORDER()`
+ returns it in network byte order.
+
+ Like the integral `GET_*()` macros, these macros work correctly on
+ both big-endian and little-endian machines and will fetch values even
+ if they are not aligned on the proper boundary.
+
+* The `GET_*()` macro that fetches an arbitrary sequences of bytes is:
+ ```
+ GET_CPY_BYTES(dst, p, len)
+ ```
+
+ where *dst* is the destination to which the sequence of bytes should
+ be copied, *p* points to the first byte of the sequence of bytes, and
+ *len* is the number of bytes to be copied. The bytes are copied in
+ the order in which they appear in the packet.
+
+* To fetch a network address and convert it to a printable string, use
+ the following `GET_*()` macros, defined in `addrtoname.h`, to
+ perform bounds checks to make sure the entire address is within the
+ buffer and to translate the address to a string to print:
+ ```
+ GET_IPADDR_STRING(p)
+ GET_IP6ADDR_STRING(p)
+ GET_MAC48_STRING(p)
+ GET_EUI64_STRING(p)
+ GET_EUI64LE_STRING(p)
+ GET_LINKADDR_STRING(p, type, len)
+ GET_ISONSAP_STRING(nsap, nsap_length)
+ ```
+
+ `GET_IPADDR_STRING()` fetches an IPv4 address pointed to by *p* and
+ returns a string that is either a host name, if the `-n` flag wasn't
+ specified and a host name could be found for the address, or the
+ standard XXX.XXX.XXX.XXX-style representation of the address.
+
+ `GET_IP6ADDR_STRING()` fetches an IPv6 address pointed to by *p* and
+ returns a string that is either a host name, if the `-n` flag wasn't
+ specified and a host name could be found for the address, or the
+ standard XXXX::XXXX-style representation of the address.
+
+ `GET_MAC48_STRING()` fetches a 48-bit MAC address (Ethernet, 802.11,
+ etc.) pointed to by *p* and returns a string that is either a host
+ name, if the `-n` flag wasn't specified and a host name could be
+ found in the ethers file for the address, or the standard
+ XX:XX:XX:XX:XX:XX-style representation of the address.
+
+ `GET_EUI64_STRING()` fetches a 64-bit EUI pointed to by *p* and
+ returns a string that is the standard XX:XX:XX:XX:XX:XX:XX:XX-style
+ representation of the address.
+
+ `GET_EUI64LE_STRING()` fetches a 64-bit EUI, in reverse byte order,
+ pointed to by *p* and returns a string that is the standard
+ XX:XX:XX:XX:XX:XX:XX:XX-style representation of the address.
+
+ `GET_LINKADDR_STRING()` fetches an octet string, of length *length*
+ and type *type*, pointed to by *p* and returns a string whose format
+ depends on the value of *type*:
+
+ * `LINKADDR_MAC48` - if the length is 6, the string has the same
+ value as `GET_MAC48_STRING()` would return for that address,
+ otherwise, the string is a sequence of XX:XX:... values for the bytes
+ of the address;
+
+ * `LINKADDR_FRELAY` - the string is "DLCI XXX", where XXX is the
+ DLCI, if the address is a valid Q.922 header, and an error indication
+ otherwise;
+
+ * `LINKADDR_EUI64`, `LINKADDR_ATM`, `LINKADDR_OTHER` -
+ the string is a sequence of XX:XX:... values for the bytes
+ of the address.
+
+6) When defining a structure corresponding to a packet or part of a
+ packet, so that a pointer to packet data can be cast to a pointer to
+ that structure and that structure pointer used to refer to fields in
+ the packet, use the `nd_*` types for the structure members.
+
+ Those types all are aligned only on a 1-byte boundary, so a
+ compiler will not assume that the structure is aligned on a boundary
+ stricter than one byte; there is no guarantee that fields in packets
+ are aligned on any particular boundary.
+
+ This means that all padding in the structure must be explicitly
+ declared as fields in the structure.
+
+ The `nd_*` types for integral values are:
+
+ * `nd_uintN_t`, for unsigned integral values, where *N* is the number
+ of bytes in the value.
+ * `nd_intN_t`, for signed integral values, where *N* is the number
+ of bytes in the value.
+
+ The `nd_*` types for IP addresses are:
+
+ * `nd_ipv4`, for IPv4 addresses;
+ * `nd_ipv6`, for IPv6 addresses.
+
+ The `nd_*` types for link-layer addresses are:

# tcpdump installation notes
If you have not built libpcap, and your system does not have libpcap
installed, install libpcap first. Your system might provide a version
of libpcap that can be installed; if so, to compile tcpdump you might
need to install a "developer" version of libpcap as well as the
-"run-time" version. You can also install tcpdump.org's version of
+"run-time" version. You can also install The Tcpdump Group version of
libpcap; see [this file](README.md) for the location.
You will need a C99 compiler to build tcpdump. The build system
will abort if your compiler is not C99 compliant. If this happens, use
the generally available GNU C compiler (GCC) or Clang.
After libpcap has been built (either install it with `make install` or
make sure both the libpcap and tcpdump source trees are in the same
-directory), run `./configure` (a shell script). `configure` will
+directory), do the following steps:
+
+* If you build from a git clone rather than from a release archive,
+run `./autogen.sh` (a shell script). The autogen.sh script will
+build the `configure` and `config.h.in` files.
+
+On some system, you may need to set the `AUTORECONF` variable, like:
+`AUTORECONF=autoreconf-2.69 ./autogen.sh`
+to select the `autoreconf` version you want to use.
+
+* Run `./configure` (a shell script). The configure script will
determine your system attributes and generate an appropriate `Makefile`
-from `Makefile.in`. Now build tcpdump by running `make`.
+from `Makefile.in`. The configure script has a number of options to
+control the configuration of tcpdump; `./configure --help` will show
+them.
+
+* Next, build tcpdump by running `make`.
+
+On OpenBSD, you may need to set, before the `make`, the `AUTOCONF_VERSION`
+variable like:
+`AUTOCONF_VERSION=2.69 make`
-If everything builds ok, `su` and type `make install`. This will install
+If everything builds fine, `su` and type `make install`. This will install
tcpdump and the manual entry. Any user will be able to use tcpdump to
read saved captures. Whether a user will be able to capture traffic
depends on the OS and the configuration of the system; see the
[tcpdump man page](https://www.tcpdump.org/manpages/tcpdump.1.html)
-for details. DO NOT give untrusted users the ability to
+for details. Do **NOT** give untrusted users the ability to
capture traffic. If a user can capture traffic, he or she could use
utilities such as tcpdump to capture any traffic on your net, including
passwords.
Note that most systems ship tcpdump, but usually an older version.
Building tcpdump from source as explained above will usually install the
binary as `/usr/local/bin/tcpdump`. If your system has other tcpdump
-binaries, you might need to deinstall these or to set the PATH environment
+binaries, you might need to deinstall these or to set the `PATH` environment
variable if you need the `tcpdump` command to run the new binary
(`tcpdump --version` can be used to tell different versions apart).
-If your system is not one which we have tested tcpdump on, you may have
+If your system is not one that we have tested tcpdump on, you may have
to modify the `configure` script and `Makefile.in`. Please
[send us patches](https://www.tcpdump.org/index.html#patches)
for any modifications you need to make.
Please see [this file](README.md) for notes about tested platforms.

# Configuration subroutine to validate and canonicalize a configuration type.
# Supply the specified configuration type as an argument.
# If it is invalid, we print an error message on stderr and exit with code 1.
# Otherwise, we print the canonical config type on stdout and succeed.
# You can get the latest version of this script from:
# https://git.savannah.gnu.org/cgit/config.git/plain/config.sub
# This file is supposed to be the same for all GNU packages
# and recognize all the CPU types, system types and aliases
# that are meaningful with *any* GNU software.
# Each package is responsible for reporting which valid configurations
# it does not support. The user should be able to distinguish
# a failure to support a valid configuration from a meaningless
# configuration.
# The goal of this file is to map all the various variations of a given
# machine specification into a single specification in the form:
# CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
# or in some cases, the newer four-part form:
# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
# It is wrong to echo any other type of specification.
# The "shellcheck disable" line above the timestamp inhibits complaints
# about features and limitations of the classic Bourne shell that were
# superseded or lifted in POSIX. However, this script identifies a wide
# variety of pre-POSIX systems that do not have POSIX shells at all, and
# even some reasonably current systems (Solaris 10 as case-in-point) still
# have a pre-POSIX /bin/sh.

+\`configure' configures tcpdump 4.99.5 to adapt to many kinds of systems.
Usage: $0 [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print \`checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for \`--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or \`..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[$ac_default_prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]

Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
+ PKG_CONFIG path to pkg-config utility
+ PKG_CONFIG_PATH
+ directories to add to pkg-config's search path
+ PKG_CONFIG_LIBDIR
+ path overriding pkg-config's built-in search path
CPP C preprocessor
+ LIBCRYPTO_CFLAGS
+ C compiler flags for libcrypto, overriding pkg-config
+ LIBCRYPTO_LIBS
+ linker flags for libcrypto, overriding pkg-config
+ LIBCRYPTO_LIBS_STATIC
+ static-link linker flags for libcrypto, overriding pkg-config
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
Report bugs to the package provider.

#
# If it supports --static-pcap-only. use that, as we will be
# linking with a static libpcap but won't be linking
# statically with any of the libraries on which it depends;
# those libraries might not even have static versions

#
# That means we need to find out the libraries on which
# libpcap directly depends, so we can link with them, but we
# don't need to link with the libraries on which those
# libraries depend as, on all UN*Xes with which I'm
# familiar, the libraries on which a shared library depends
# are stored in the library and are automatically loaded by
# the run-time linker, without the executable having to be
# linked with those libraries. (This allows a library to be
# changed to depend on more libraries without breaking that
# library's ABI.)
#
# The only way to test for that support is to see if the
# script contains the string "static-pcap-only"; we can't
# try using that flag and checking for errors, as the
# versions of the script that didn't have that flag wouldn't
# report or return an error for an unsupported command-line
# flag. Those older versions provided, with --static, only
# the libraries on which libpcap depends, not the
# dependencies of those libraries; the versions with
# --static-pcap-only provide all the dependencies with
# --static, for the benefit of programs that are completely

-Building tcpdump on Windows with Visual Studio
-==============================================
-
-Unlike the UN*Xes on which libpcap can capture network traffic, Windows
-has no network traffic capture mechanism that libpcap can use.
-Therefore, libpcap requires a driver, and a library to access the
-driver, provided by the Npcap or WinPcap projects.
-
-Those projects include versions of libpcap built to use that driver and
-library; these instructions are for people who want to build libpcap
-source releases, or libpcap from the Git repository, as a replacement
-for the version provided with Npcap or WinPcap.
-
-Npcap and WinPcap SDK
----------------------
-
-In order to build tcpdump, you will need to download Npcap and its
-software development kit (SDK) or WinPcap and its software development
-kit.
-
-Npcap is currently being developed and maintained, and offers many
-additional capabilities that WinPcap does not.
-
-WinPcap is no longer being developed or maintained; it should be used
-only if there is some other requirement to use it rather than Npcap,
-such as a requirement to support versions of Windows earlier than
-Windows Vista, which is the earliest version supported by Npcap.
-
-Npcap and its SDK can be downloaded from its [home page](https://npcap.com).
-The SDK is a ZIP archive; create a folder on your `C:` drive, e.g.
-`C:\npcap-sdk`, and put the contents of the ZIP archive into that folder.
-
-The WinPcap installer can be downloaded from
-[here](https://www.winpcap.org/install/default.htm)
-and the WinPcap Developer's Kit can be downloaded from
-[here](https://www.winpcap.org/devel.htm).
-
-Required build tools
---------------------
-
-The Developer's Kit is a ZIP archive; it contains a folder named
-`WpdPack`, which you should place on your `C:` drive, e.g. `C:\WpdPack`.
-
-Building tcpdump on Windows requires Visual Studio 2015 or later. The
-Community Edition of Visual Studio can be downloaded at no cost from
-[here](https://visualstudio.microsoft.com).
-
-Additional tools are also required. Chocolatey is a package manager for
-Windows with which those tools, and other tools, can be installed; it
-can be downloaded from [here](https://chocolatey.org).
-
-It is a command-line tool; a GUI tool, Chocolatey GUI, is provided as a
-Chocolatey package, which can be installed from the command line:
-
-```
-choco install chocolateygui
-```
-
-For convenience, the `choco install` command can be run with the `-y`
-flag, forcing it to automatically answer all questions asked of the user
-with "yes":
-
-```
-choco install -y chocolateygui
-```
-
-The required tools are:
-
-### CMake ###
-
-libpcap does not provide supported project files for Visual Studio
-(there are currently unsupported project files provided, but we do not
-guarantee that they will work or that we will continue to provide them).
-It does provide files for CMake, which is a cross-platform tool that
-runs on UN\*Xes and on Windows and that can generate project files for
-UN\*X Make, the Ninja build system, and Visual Studio, among other build
-systems.
-
-Visual Studio 2015 does not provide CMake; an installer can be
-downloaded from [here](https://cmake.org/download/).
-
-When you run the installer, you should choose to add CMake to the system
-`PATH` for all users and to create the desktop icon.
-
-CMake can also be installed as the Chocolatey package `cmake`:
-
-```
-choco install -y cmake
-```
-
-Visual Studio 2017 and later provide CMake, so you will not need to
-install CMake if you have installed Visual Studio 2017 or later. They
-include built-in support for CMake-based projects as described
-[here](https://devblogs.microsoft.com/cppblog/cmake-support-in-visual-studio/).
-
-For Visual Studio 2017, make sure "Visual C++ tools for CMake" is
-installed; for Visual Studio 2019, make sure "C++ CMake tools for
-Windows" is installed.
-
-Git
----
-
-An optional tool, required only if you will be building from a Git
-repository rather than from a release source tarball, is Git. Git is
-provided as an optional installation component, "Git for Windows", with
-Visual Studio 2017 and later.
-
-Building from the Visual Studio GUI
------------------------------------
-
-### Visual Studio 2017 ###
-
-Open the folder containing the libpcap source with Open > Folder.
-Visual Studio will run CMake; however, you will need to indicate where
-the Npcap or WinPcap SDK is installed.
-
-To do this, go to Project > "Change CMake Settings" > tcpdump and:
-
-Choose which configuration type to build, if you don't want the default
-Debug build.
-
-In the CMakeSettings.json tab, change cmakeCommandArgs to include
-
-```
--DPacket_ROOT={path-to-sdk}
-```
-
-where `{path-to-sdk}` is the path of the directory containing the Npcap or
-WinPcap SDK. Note that backslashes in the path must be specified as two
-backslashes.
-
-Save the configuration changes with File > "Save CMakeSettings.json" or
-with Control-S.
-
-Visual Studio will then re-run CMake. If that completes without errors,
-you can build with CMake > "Build All".
-
-### Visual Studio 2019 ###
-
-Open the folder containing the libpcap source with Open > Folder.
-Visual Studio will run CMake; however, you will need to indicate where
-the Npcap or WinPcap SDK is installed.
-
-To do this, go to Project > "CMake Settings for tcpdump" and:
-
-Choose which configuration type to build, if you don't want the default
-Debug build.
-
-Scroll down to "Cmake variables and cache", scroll through the list
-looking for the entry for Packet_ROOT, and either type in the path of
-the directory containing the Npcap or WinPcap SDK or use the "Browse..."
-button to browse for that directory.
-
-Save the configuration changes with File > "Save CMakeSettings.json" or
-with Control-S.
-
-Visual Studio will then re-run CMake. If that completes without errors,
-you can build with Build > "Build All".
-
-Building from the command line
-------------------------------
-
-Start the appropriate Native Tools command line prompt.
-
-Change to the directory into which you want to build tcpdump, possibly
-after creating it first. One choice is to create it as a subdirectory
-of the tcpdump source directory.
-
-Run the command
-
-```
-cmake "-DPacket_ROOT={path-to-sdk}" -G {generator} {path-to-tcpdump-source}
-```
-
-`{path-to-sdk}` is the path of the directory containing the Npcap or
-WinPcap SDK.
-
-`{generator}` is the string "Visual Studio N YYYY", where `N` is the
-version of Visual Studio and `YYYY` is the year number for that version;
-if you are building a 64-bit version of tcpdump, `YYYY` must be followed
-by a space and "Win64". For example, to build a 32-bit version of
-tcpdump with Visual Studio 2017, `{generator}` would be "Visual Studio
-15 2017" and to build a 64-bit version of tcpdump with Visual Studio
-2017, `{generator}` would be "Visual Studio 15 2017 Win64".
-
-`{path-to-tcpdump-source}` is the pathname of the top-level source
-directory for tcpdump.
-
-Run the command
-
-```
-msbuild /m /nologo /p:Configuration={configuration} tcpdump.sln
-```
-
-where `{configuration}` can be "Release", "Debug", or "RelWithDebInfo".
-
-Building with MinGW

*
* "sum" is the value of the checksum field, and "computed_sum"

*
* All the arithmetic in question is one's complement, so the

* doing the arithmetic in 32 bits (with no sign-extension),
* and then adding the upper 16 bits of the sum, which contain
* the carry, to the lower 16 bits of the sum, and then do it
* again in case *that* sum produced a carry.
*
* As RFC 1071 notes, the checksum can be computed without
* byte-swapping the 16-bit words; summing 16-bit words
* on a big-endian machine gives a big-endian checksum, which
* can be directly stuffed into the big-endian checksum fields
* in protocol headers, and summing words on a little-endian
* machine gives a little-endian checksum, which must be
* byte-swapped before being stuffed into a big-endian checksum
* field.
*
* "computed_sum" is a network-byte-order value, so we must put
* it in host byte order before subtracting it from the
* host-byte-order value from the header; the adjusted checksum
* will be in host byte order, which is what we'll return.

From Bill Fenner:
The Arista timestamp header consists of the following fields:
1. The Arista ethertype (0xd28b)
2. A 2-byte subtype field; 0x01 indicates the timestamp header
3. A 2-byte version field, described below.
4. A 48-bit or 64-bit timestamp field, depending on the contents of the version field
This header is then followed by the original ethertype and the remainder of the original packet.
0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

The two-byte version value is split into 3 fields:

0 = TAI
1 = UTC
2. The timestamp format and length. Currently assigned values include:
1 = 64-bit timestamp
2 = 48-bit timestamp
3. The hardware info

* Sub-TLVs consume the "extra data" of Babel TLVs (see Section 4.3 of RFC6126),

*
* o Type 0 stands for Pad1 sub-TLV with the same encoding as the Pad1 TLV.
* o Type 1 stands for PadN sub-TLV with the same encoding as the PadN TLV.
* o Type 2 stands for Diversity sub-TLV, which propagates diversity routing
* data. Its body is a variable-length sequence of 8-bit unsigned integers,
* each representing per-hop number of interfering radio channel for the
* prefix. Channel 0 is invalid and must not be used in the sub-TLV, channel
* 255 interferes with any other channel.
* o Type 3 stands for Timestamp sub-TLV, used to compute RTT between
* neighbours. In the case of a Hello TLV, the body stores a 32-bits
* timestamp, while in the case of a IHU TLV, two 32-bits timestamps are
* stored.
*
* Sub-TLV types 0 and 1 are valid for any TLV type, whether sub-TLV type 2 is
* only valid for TLV type 8 (Update). Note that within an Update TLV a missing
* Diversity sub-TLV is not the same as a Diversity sub-TLV with an empty body.
* The former would mean a lack of any claims about the interference, and the
* latter would state that interference is definitely absent.
* A type 3 sub-TLV is valid both for Hello and IHU TLVs, though the exact
* semantic of the sub-TLV is different in each case.

/*
* FDDI support for tcpdump, by Jeffrey Mogul [DECWRL], June 1992
*
* Based in part on code by Van Jacobson, which bears this note:
*
* NOTE: This is a very preliminary hack for FDDI support.
* There are all sorts of wired in constants & nothing (yet)
* to print SMT packets as anything other than hex dumps.
* Most of the necessary changes are waiting on my redoing
* the "header" that a kernel fddi driver supplies to bpf: I
* want it to look like one byte of 'direction' (0 or 1
* depending on whether the packet was inbound or outbound),
* two bytes of system/driver dependent data (anything an
* implementor thinks would be useful to filter on and/or
* save per-packet, then the real 21-byte FDDI header.
* Steve McCanne & I have also talked about adding the
* 'direction' byte to all bpf headers (e.g., in the two
* bytes of padding on an ethernet header). It's not clear
* we could do this in a backwards compatible way & we hate
* the idea of an incompatible bpf change. Discussions are
* proceeding.
*
* Also, to really support FDDI (and better support 802.2
* over ethernet) we really need to re-think the rather simple
* minded assumptions about fixed length & fixed format link
* level headers made in gencode.c. One day...
*

/*
* This module implements decoding of OpenFlow protocol version 1.0 (wire
* protocol 0x01). The decoder implements terse (default), detailed (-v) and
* full (-vv) output formats and, as much as each format implies, detects and
* tries to work around sizing anomalies inside the messages. The decoder marks
* up bogus values of selected message fields and decodes partially captured
* messages up to the snapshot end. It is based on the specification below:
*
* [OF10] https://www.opennetworking.org/wp-content/uploads/2013/04/openflow-spec-v1.0.0.pdf
*
* Most functions in this file take the following arguments:
* * cp -- the pointer to the first octet to decode
* * len -- the declared length of the structure to decode
* The convention is that a printer function returns iff the given structure is
* completely within the packet buffer; otherwise it processes the part that is
* within the buffer, sooner of later takes the "truncated packet" shortcut via
* longjmp() and never returns. With that in mind, the function may return
* without printing the structure completely if it is invalid or the ndo_vflag
* value is not high enough. This way the calling function can try to decode
* the next data item.
*
* Decoding of Ethernet frames nested in OFPT_PACKET_IN and OFPT_PACKET_OUT
* messages is done only when the verbosity level set by command-line argument
* is "-vvv" or higher. In that case the verbosity level is temporarily
* decremented by 3 during the nested frame decoding. For example, running
* tcpdump with "-vvvv" will do full decoding of OpenFlow and "-v" decoding of
* the nested frames.
*
* Partial decoding of Big Switch Networks vendor extensions is done after the
* oftest (OpenFlow Testing Framework) and Loxigen (library generator) source
* code.

* PIMv2 uses encoded address representations.

* specified no encoding for unicast addresses with the unicast
* address length specified in the header. Therefore, we have to
* guess which encoding is being used (Cisco's PIMv2 implementation
* uses the non-RFC encoding). RFC2117 turns a previously "Reserved"
* field into a 'unicast-address-length-in-bytes' field. We guess
* that it's the draft encoding if this reserved field is zero.
*
* RFC2362 goes back to the encoded format, and calls the addr length
* field "reserved" again.
*
* The first byte is the address family, from:
*
* 0 Reserved
* 1 IP (IP version 4)
* 2 IP6 (IP version 6)
* 3 NSAP

*
* That was what the original tcpdump code did.
*
* FreeBSD's "if_ppp.c" *does* set the first octet to 1 for outbound
* packets and 0 for inbound packets - but only if the
* protocol field has the 0x8000 bit set (i.e., it's a network
* control protocol); it does so before running the packet through
* "bpf_filter" to see if it should be discarded, and to see
* if we should update the time we sent the most recent packet...
*
* ...but it puts the original address field back after doing
* so.
*
* NetBSD's "if_ppp.c" doesn't set the first octet in that fashion.
*
* I don't know if any PPP implementation handed up to a BPF
* device packets with the first octet being 1 for outbound and
* 0 for inbound packets, so I (guy@alum.mit.edu) don't know
* whether that ever needs to be checked or not.
*
* Note that NetBSD has a DLT_PPP_SERIAL, which it uses for PPP,
* and its tcpdump appears to assume that the frame always
* begins with an address field and a control field, and that
* the address field might be 0x0f or 0x8f, for Cisco
* point-to-point with HDLC framing as per section 4.3.1 of RFC
* 1547, as well as 0xff, for PPP in HDLC-like framing as per

* followed by the MAC address that appears in the source address in the

* This implementation has been influenced by the CMU SNMP release,

* Additional ASN.1 insight gained from Marshall T. Rose's _The_Open_Book_.
* Earlier forms of this implementation were derived and/or inspired by an
* awk script originally written by C. Philip Wood of LANL (but later
* heavily modified by John Robert LoVerso). The copyright notice for
* that work is preserved below, even though it may not rightly apply
* to this file.
*
* Support for SNMPv2c/SNMPv3 and the ability to link the module against
* the libsmi was added by J. Schoenwaelder, Copyright (c) 1999.
*
* This started out as a very simple program, but the incremental decoding
* (into the BE structure) complicated things.

* The following procedures are supported by the protocol:
*
* PMAPPROC_NULL() returns ()

*
* PMAPPROC_SET(struct pmap) returns (bool_t)
* TRUE is success, FALSE is failure. Registers the tuple
* [prog, vers, prot, port].
*
* PMAPPROC_UNSET(struct pmap) returns (bool_t)
* TRUE is success, FALSE is failure. Un-registers pair
* [prog, vers]. prot and port are ignored.
*
* PMAPPROC_GETPORT(struct pmap) returns (long unsigned).
* 0 is failure. Otherwise returns the port number where the pair
* [prog, vers] is registered. It may lie!
*
* PMAPPROC_DUMP() RETURNS (struct pmaplist *)
*
* PMAPPROC_CALLIT(unsigned, unsigned, unsigned, string<>)
* RETURNS (port, string<>);
* usage: encapsulatedresults = PMAPPROC_CALLIT(prog, vers, proc, encapsulatedargs);
* Calls the procedure on the local machine. If it is not registered,

* XXX - for BSD/OS PPP, what packets get supplied with a PPP header type
* of PPP_VJC and what packets get supplied with a PPP header type of
* PPP_VJNC? PPP_VJNC is for "UNCOMPRESSED_TCP" packets, and PPP_VJC
* is for COMPRESSED_TCP packets (PPP_IP is used for TYPE_IP packets).
*
* RFC 1144 implies that, on the wire, the packet type is *not* needed
* for PPP, as different PPP protocol types can be used; it only needs
* to be put on the wire for SLIP.
*
* It also indicates that, for compressed SLIP:
*
* If the COMPRESSED_TCP bit is set in the first byte, it's
* a COMPRESSED_TCP packet; that byte is the change byte, and
* the COMPRESSED_TCP bit, 0x80, isn't used in the change byte.
*
* If the upper 4 bits of the first byte are 7, it's an
* UNCOMPRESSED_TCP packet; that byte is the first byte of
* the UNCOMPRESSED_TCP modified IP header, with a connection
* number in the protocol field, and with the version field
* being 7, not 4.
*
* Otherwise, the packet is an IPv4 packet (where the upper 4 bits
* of the packet are 4).
*
* So this routine looks as if it's sort-of intended to handle
* compressed SLIP, although it doesn't handle UNCOMPRESSED_TCP
* correctly for that (it doesn't fix the version number and doesn't
* do anything to the protocol field), and doesn't check for COMPRESSED_TCP
* packets correctly for that (you only check the first bit - see
* B.1 in RFC 1144).
*
* But it's called for BSD/OS PPP, not SLIP - perhaps BSD/OS does weird
* things with the headers?
*
* Without a BSD/OS VJC-compressed PPP trace, or knowledge of what the
* BSD/OS VJC code does, we can't say what's the case.
*
* We therefore leave "proto" - which is the PPP protocol type - in place,
* *not* marked as unused, for now, so that GCC warnings about the
* unused argument remind us that we should fix this some day.
*
* XXX - also, it fetches the TCP checksum field in COMPRESSED_TCP
* packets with GET_HE_U_2, rather than with GET_BE_U_2(); RFC 1144 says
* it's "the unmodified TCP checksum", which would imply that it's
* big-endian, but perhaps, on the platform where this was developed,
* the packets were munged by the networking stack before being handed
* to the packet capture mechanism.

* Below is an excerpt from the "13/ZMTP" specification:
*
* A ZMTP message consists of 1 or more frames.
*
* A ZMTP frame consists of a length, followed by a flags field and a frame
* body of (length - 1) octets. Note: the length includes the flags field, so
* an empty frame has a length of 1.
*
* For frames with a length of 1 to 254 octets, the length SHOULD BE encoded
* as a single octet. The minimum valid length of a frame is 1 octet, thus a
* length of 0 is invalid and such frames SHOULD be discarded silently.
*
* For frames with lengths of 255 and greater, the length SHALL BE encoded as
* a single octet with the value 255, followed by the length encoded as a
* 64-bit unsigned integer in network byte order. For frames with lengths of
* 1 to 254 octets this encoding MAY be also used.
*
* The flags field consists of a single octet containing various control
* flags. Bit 0 is the least significant bit.
*
* - Bit 0 (MORE): More frames to follow. A value of 0 indicates that there
* are no more frames to follow. A value of 1 indicates that more frames
* will follow. On messages consisting of a single frame the MORE flag MUST
* be 0.
*
* - Bits 1-7: Reserved. Bits 1-7 are reserved for future use and SHOULD be
* zero.

.SH DESCRIPTION
.LP
\fITcpdump\fP prints out a description of the contents of packets on a
network interface that match the Boolean \fIexpression\fP (see
.BR \%pcap-filter (@MAN_MISC_INFO@)
for the \fIexpression\fP syntax); the
description is preceded by a time stamp, printed, by default, as hours,
minutes, seconds, and fractions of a second since midnight. It can also
be run with the
.B \-w
flag, which causes it to save the packet data to a file for later
analysis, and/or with the
.B \-r
flag, which causes it to read from a saved packet file rather than to
read packets from a network interface. It can also be run with the
.B \-V
flag, which causes it to read a list of saved packet files. In all cases,
only packets that match
.I expression
will be processed by
.IR tcpdump .
.LP
.I Tcpdump
will, if not run with the
.B \-c
flag, continue capturing packets until it is interrupted by a SIGINT
signal (generated, for example, by typing your interrupt character,
typically control-C) or a SIGTERM signal (typically generated with the
.BR kill (1)
command); if run with the
.B \-c
flag, it will capture packets until it is interrupted by a SIGINT or
SIGTERM signal or the specified number of packets have been processed.
.LP
When
.I tcpdump
finishes capturing packets, it will report counts of:
.IP
packets ``captured'' (this is the number of packets that
.I tcpdump
has received and processed);
.IP
packets ``received by filter'' (the meaning of this depends on the OS on
which you're running
.IR tcpdump ,
and possibly on the way the OS was configured - if a filter was
specified on the command line, on some OSes it counts packets regardless
of whether they were matched by the filter expression and, even if they
were matched by the filter expression, regardless of whether
.I tcpdump
has read and processed them yet, on other OSes it counts only packets that were
matched by the filter expression regardless of whether
.I tcpdump
has read and processed them yet, and on other OSes it counts only
packets that were matched by the filter expression and were processed by
.IR tcpdump );
.IP
packets ``dropped by kernel'' (this is the number of packets that were
dropped, due to a lack of buffer space, by the packet capture mechanism
in the OS on which
.I tcpdump
is running, if the OS reports that information to applications; if not,
it will be reported as 0).
.LP
On platforms that support the SIGINFO signal, such as most BSDs
(including macOS) and Digital/Tru64 UNIX, it will report those counts
when it receives a SIGINFO signal (generated, for example, by typing
your ``status'' character, typically control-T, although on some
platforms, such as macOS, the ``status'' character is not set by
default, so you must set it with
.BR stty (1)
in order to use it) and will continue capturing packets. On platforms that
do not support the SIGINFO signal, the same can be achieved by using the
SIGUSR1 signal.
.LP
Using the SIGUSR2 signal along with the
.B \-w
flag will forcibly flush the packet buffer into the output file.
.LP
Reading packets from a network interface may require that you have
special privileges; see the
.BR pcap (3PCAP)
man page for details. Reading a saved packet file doesn't require
special privileges.
.SH OPTIONS
.TP
.B \-A
Print each packet (minus its link level header) in ASCII. Handy for
capturing web pages.
.TP
.B \-b
Print the AS number in BGP packets in ASDOT notation rather than ASPLAIN
notation.
.TP
.BI \-B " buffer_size"
.PD 0
.TP
.BI \-\-buffer\-size= buffer_size
.PD
Set the operating system capture buffer size to \fIbuffer_size\fP, in
units of KiB (1024 bytes).
.TP
.BI \-c " count"
Exit after receiving \fIcount\fP packets.
.TP
.BI \-\-count
Print only on stdout the packet count when reading capture file(s) instead
of parsing/printing the packets. If a filter is specified on the command
line, \fItcpdump\fP counts only packets that were matched by the filter
expression.
.TP
.BI \-C " file_size"
Before writing a raw packet to a savefile, check whether the file is
currently larger than \fIfile_size\fP and, if so, close the current
savefile and open a new one. Savefiles after the first savefile will
have the name specified with the
.B \-w
flag, with a number after it, starting at 1 and continuing upward.
The units of \fIfile_size\fP are millions of bytes (1,000,000 bytes,
not 1,048,576 bytes).
.TP
.B \-d
Dump the compiled packet-matching code in a human readable form to
standard output and stop.
.IP
Please mind that although code compilation is always DLT-specific,
typically it is impossible (and unnecessary) to specify which DLT to use
for the dump because \fItcpdump\fP uses either the DLT of the input pcap
file specified with
.BR -r ,
or the default DLT of the network interface specified with
.BR -i ,
or the particular DLT of the network interface specified with
.B -y
and
.B -i
respectively. In these cases the dump shows the same exact code that
would filter the input file or the network interface without
.BR -d .
.IP
However, when neither
.B -r
nor
.B -i
is specified, specifying
.B -d
prevents \fItcpdump\fP from guessing a suitable network interface (see
.BR -i ).
In this case the DLT defaults to EN10MB and can be set to another valid
value manually with
.BR -y .
.TP
.B \-dd
Dump packet-matching code as a
.B C
program fragment.
.TP
.B \-ddd
Dump packet-matching code as decimal numbers (preceded with a count).
.TP
.B \-D
.PD 0
.TP
.B \-\-list\-interfaces
.PD
Print the list of the network interfaces available on the system and on
which
.I tcpdump
can capture packets. For each network interface, a number and an
interface name, possibly followed by a text description of the
interface, are printed. The interface name or the number can be supplied
to the
.B \-i
flag to specify an interface on which to capture.
.IP
This can be useful on systems that don't have a command to list them
(e.g., Windows systems, or UNIX systems lacking
.BR "ifconfig \-a" );
the number can be useful on Windows 2000 and later systems, where the
interface name is a somewhat complex string.
.IP
The
.B \-D
flag will not be supported if
.I tcpdump
was built with an older version of
.I libpcap
that lacks the
.BR pcap_findalldevs (3PCAP)
function.
.TP
.B \-e
Print the link-level header on each dump line. This can be used, for
example, to print MAC layer addresses for protocols such as Ethernet and
IEEE 802.11.
.TP
.B \-E
Use \fIspi@ipaddr algo:secret\fP for decrypting IPsec ESP packets that
are addressed to \fIaddr\fP and contain Security Parameter Index value
\fIspi\fP. This combination may be repeated with comma or newline separation.
.IP
Note that setting the secret for IPv4 ESP packets is supported at this time.
.IP
Algorithms may be
\fBdes-cbc\fP,
\fB3des-cbc\fP,
\fBblowfish-cbc\fP,
\fBrc3-cbc\fP,
\fBcast128-cbc\fP, or
\fBnone\fP.
The default is \fBdes-cbc\fP.
The ability to decrypt packets is only present if \fItcpdump\fP was compiled
with cryptography enabled.
.IP
\fIsecret\fP is the ASCII text for ESP secret key.
If preceded by 0x, then a hex value will be read.
.IP
The option assumes RFC 2406 ESP, not RFC 1827 ESP.
The option is only for debugging purposes, and
the use of this option with a true `secret' key is discouraged.
By presenting IPsec secret key onto command line
you make it visible to others, via
.IR ps (1)
and other occasions.
.IP
In addition to the above syntax, the syntax \fIfile name\fP may be used
to have tcpdump read the provided file in. The file is opened upon
receiving the first ESP packet, so any special permissions that tcpdump
may have been given should already have been given up.
.TP
.B \-f
Print `foreign' IPv4 addresses numerically rather than symbolically
(this option is intended to get around serious brain damage in
Sun's NIS server \(em usually it hangs forever translating non-local
internet numbers).
.IP
The test for `foreign' IPv4 addresses is done using the IPv4 address and
netmask of the interface on that capture is being done. If that
address or netmask are not available, either because the
interface on that capture is being done has no address or netmask or
because it is the "any" pseudo-interface, which is
available in Linux and in recent versions of macOS and Solaris, and which
can capture on more than one interface, this option will not work
correctly.
.TP
.BI \-F " file"
Use \fIfile\fP as input for the filter expression.
An additional expression given on the command line is ignored.
.TP
.BI \-G " rotate_seconds"
If specified, rotates the dump file specified with the
.B \-w
option every \fIrotate_seconds\fP seconds.
Savefiles will have the name specified by
.B \-w
which should include a time format as defined by
.BR strftime (3).
If no time format is specified, each new file will overwrite the previous.
Whenever a generated filename is not unique, tcpdump will overwrite the
-pre-existing data; providing a time specification that is coarser than the
+preexisting data; providing a time specification that is coarser than the
capture period is therefore not advised.
.IP
If used in conjunction with the
.B \-C
option, filenames will take the form of `\fIfile\fP<count>'.
.TP
.B \-h
.PD 0
.TP
.B \-\-help
.PD
Print the tcpdump and libpcap version strings, print a usage message,
and exit.
.TP
.B \-\-version
.PD
Print the tcpdump and libpcap version strings and exit.
.TP
.B \-H
Attempt to detect 802.11s draft mesh headers.
.TP
.BI \-i " interface"
.PD 0
.TP
.BI \-\-interface= interface
.PD
Listen, report the list of link-layer types, report the list of time
stamp types, or report the results of compiling a filter expression on
\fIinterface\fP. If unspecified and if the
.B -d
flag is not given, \fItcpdump\fP searches the system
interface list for the lowest numbered, configured up interface
(excluding loopback), which may turn out to be, for example, ``eth0''.
.IP
On Linux systems with 2.2 or later kernels and on recent versions of macOS
and Solaris, an
.I interface
argument of ``any'' can be used to capture packets from all interfaces.
Note that captures on the ``any'' pseudo-interface will not be done in promiscuous
mode.
.IP
If the
.B \-D
flag is supported, an interface number as printed by that flag can be
used as the
.I interface
argument, if no interface on the system has that number as a name.
.TP
.B \-I
.PD 0
.TP
.B \-\-monitor\-mode
.PD
Put the interface in "monitor mode"; this is supported only on IEEE
802.11 Wi-Fi interfaces, and supported only on some operating systems.
.IP
Note that in monitor mode the adapter might disassociate from the
network with which it's associated, so that you will not be able to use
any wireless networks with that adapter. This could prevent accessing
files on a network server, or resolving host names or network addresses,
if you are capturing in monitor mode and are not connected to another
network with another adapter.
.IP
This flag will affect the output of the
.B \-L
flag. If
.B \-I
isn't specified, only those link-layer types available when not in
monitor mode will be shown; if
.B \-I
is specified, only those link-layer types available when in monitor mode
will be shown.
.TP
.BI \-\-immediate\-mode
Capture in "immediate mode". In this mode, packets are delivered to
tcpdump as soon as they arrive, rather than being buffered for
efficiency. This is the default when printing packets rather than
saving packets to a ``savefile'' if the packets are being printed to a
terminal rather than to a file or pipe.
.TP
.BI \-j " tstamp_type"
.PD 0
.TP
.BI \-\-time\-stamp\-type= tstamp_type
.PD
Set the time stamp type for the capture to \fItstamp_type\fP. The names
to use for the time stamp types are given in
.BR \%pcap-tstamp (@MAN_MISC_INFO@);
not all the types listed there will necessarily be valid for any given
interface.
.TP
.B \-J
.PD 0
.TP
.B \-\-list\-time\-stamp\-types
.PD
List the supported time stamp types for the interface and exit. If the
time stamp type cannot be set for the interface, no time stamp types are
listed.
.TP
.BI \-\-time\-stamp\-precision= tstamp_precision
When capturing, set the time stamp precision for the capture to
\fItstamp_precision\fP. Note that availability of high precision time
stamps (nanoseconds) and their actual accuracy is platform and hardware
dependent. Also note that when writing captures made with nanosecond
accuracy to a savefile, the time stamps are written with nanosecond
resolution, and the file is written with a different magic number, to
indicate that the time stamps are in seconds and nanoseconds; not all
programs that read pcap savefiles will be able to read those captures.
.IP
When reading a savefile, convert time stamps to the precision specified
by \fItimestamp_precision\fP, and display them with that resolution. If
the precision specified is less than the precision of time stamps in the
file, the conversion will lose precision.
.IP
The supported values for \fItimestamp_precision\fP are \fBmicro\fP for
microsecond resolution and \fBnano\fP for nanosecond resolution. The
default is microsecond resolution.
.TP
.B \-\-micro
.PD 0
.TP
.B \-\-nano
.PD
Shorthands for \fB\-\-time\-stamp\-precision=micro\fP or
\fB\-\-time\-stamp\-precision=nano\fP, adjusting the time stamp
precision accordingly. When reading packets from a savefile, using
\fB\-\-micro\fP truncates time stamps if the savefile was created with
nanosecond precision. In contrast, a savefile created with microsecond
precision will have trailing zeroes added to the time stamp when
\fB\-\-nano\fP is used.
.TP
.B \-K
.PD 0
.TP
.B \-\-dont\-verify\-checksums
.PD
Don't attempt to verify IP, TCP, or UDP checksums. This is useful for
interfaces that perform some or all of those checksum calculation in
hardware; otherwise, all outgoing TCP checksums will be flagged as bad.
.TP
.B \-l
Make stdout line buffered.
Useful if you want to see the data
while capturing it.
E.g.,
.IP
.RS
.RS
.nf
\fBtcpdump \-l | tee dat\fP
.fi
.RE
.RE
.IP
or
.IP
.RS
.RS
.nf
\fBtcpdump \-l > dat & tail \-f dat\fP
.fi
.RE
.RE
.IP
Note that on Windows,``line buffered'' means ``unbuffered'', so that
WinDump will write each character individually if
.B \-l
is specified.
.IP
.B \-U
is similar to
.B \-l
in its behavior, but it will cause output to be ``packet-buffered'', so
that the output is written to stdout at the end of each packet rather
than at the end of each line; this is buffered on all platforms,
including Windows.
.TP
.B \-L
.PD 0

List the known data link types for the interface, in the specified mode,

specified mode; for example, on some platforms, a Wi-Fi interface might
support one set of data link types when not in monitor mode (for
example, it might support only fake Ethernet headers, or might support
802.11 headers but not support 802.11 headers with radio information)
and another set of data link types when in monitor mode (for example, it
might support 802.11 headers, or 802.11 headers with radio information,
only in monitor mode).

.BI \-\-snapshot\-length= snaplen
.PD
Snarf \fIsnaplen\fP bytes of data from each packet rather than the

Packets truncated because of a limited snapshot
are indicated in the output with ``[|\fIproto\fP]'', where \fIproto\fP
is the name of the protocol level at which the truncation has occurred.
.IP
Note that taking larger snapshots both increases
the amount of time it takes to process packets and, effectively,
decreases the amount of packet buffering.
This may cause packets to be
lost.
Note also that taking smaller snapshots will discard data from protocols
above the transport layer, which loses information that may be
important. NFS and AFS requests and replies, for example, are very
large, and much of the detail won't be available if a too-short snapshot
length is selected.
.IP
If you need to reduce the snapshot size below the default, you should
limit \fIsnaplen\fP to the smallest number that will capture the
protocol information you're interested in. Setting
\fIsnaplen\fP to 0 sets it to the default of 262144,
for backwards compatibility with recent older versions of
.IR tcpdump .
.TP
.BI \-T " type"
Force packets selected by "\fIexpression\fP" to be interpreted the

Currently known types are
\fBaodv\fR (Ad-hoc On-demand Distance Vector protocol),
\fBcarp\fR (Common Address Redundancy Protocol),
\fBcnfp\fR (Cisco NetFlow protocol),
\fBdomain\fR (Domain Name System),
\fBlmp\fR (Link Management Protocol),
\fBpgm\fR (Pragmatic General Multicast),
\fBpgm_zmtp1\fR (ZMTP/1.0 inside PGM/EPGM),
\fBptp\fR (Precision Time Protocol),

\fBvat\fR (Visual Audio Tool),
\fBvxlan\fR (Virtual eXtensible Local Area Network),
\fBwb\fR (distributed White Board)

\fBzmtp1\fR (ZeroMQ Message Transport Protocol 1.0).
.IP
Note that the \fBpgm\fR type above affects UDP interpretation only, the native
PGM is always recognised as IP protocol 113 regardless. UDP-encapsulated PGM is
often called "EPGM" or "PGM/UDP".
.IP
Note that the \fBpgm_zmtp1\fR type above affects interpretation of both native
PGM and UDP at once. During the native PGM decoding the application data of an
ODATA/RDATA packet would be decoded as a ZeroMQ datagram with ZMTP/1.0 frames.
During the UDP decoding in addition to that any UDP packet would be treated as
an encapsulated PGM packet.

.B \-\-packet\-buffered
.PD
If the
.B \-w
option is not specified, or if it is specified but the
.B \-\-print
flag is also specified, make the printed packet output
``packet-buffered''; i.e., as the description of the contents of each
packet is printed, it will be written to the standard output, rather
than, when not writing to a terminal, being written only when the output
buffer fills.
.IP
If the
.B \-w
option is specified, make the saved raw packet output
``packet-buffered''; i.e., as each packet is saved, it will be written
to the output file, rather than being written only when the output
buffer fills.
.IP
The
.B \-U
flag will not be supported if
.I tcpdump
was built with an older version of
.I libpcap
that lacks the
.BR pcap_dump_flush (3PCAP)
function.
.TP
.B \-v
When parsing and printing, produce (slightly more) verbose output.
For example, the time to live,
identification, total length and options in an IP packet are printed.
Also enables additional packet integrity checks such as verifying the
IP and ICMP header checksum.
.IP
When writing to a file with the
.B \-w
option and at the same time not reading from a file with the
.B \-r
option, report to stderr, once per second, the number of packets captured. In
Solaris, FreeBSD and possibly other operating systems this periodic update
currently can cause loss of captured packets on their way from the kernel to
tcpdump.
.TP
.B \-vv
Even more verbose output.
For example, additional fields are
printed from NFS reply packets, and SMB packets are fully decoded.
.TP
.B \-vvv
Even more verbose output.
For example,
telnet \fBSB\fP ... \fBSE\fP options
are printed in full.
With
.B \-X
Telnet options are printed in hex as well.
.TP
.BI \-V " file"
Read a list of filenames from \fIfile\fR. Standard input is used
if \fIfile\fR is ``-''.
.TP
.BI \-w " file"
Write the raw packets to \fIfile\fR rather than parsing and printing
them out.
They can later be printed with the \-r option.
Standard output is used if \fIfile\fR is ``-''.
.IP
This output will be buffered if written to a file or pipe, so a program
reading from the file or pipe may not see packets for an arbitrary
amount of time after they are received. Use the
.B \-U
flag to cause packets to be written as soon as they are received.
.IP
The MIME type \fIapplication/vnd.tcpdump.pcap\fP has been registered
with IANA for \fIpcap\fP files. The filename extension \fI.pcap\fP
appears to be the most commonly used along with \fI.cap\fP and
\fI.dmp\fP. \fITcpdump\fP itself doesn't check the extension when
reading capture files and doesn't add an extension when writing them
(it uses magic numbers in the file header instead). However, many
operating systems and applications will use the extension if it is
present and adding one (e.g. .pcap) is recommended.
.IP
See
.BR \%pcap-savefile (@MAN_FILE_FORMATS@)
for a description of the file format.
.TP
.BI \-W " filecount"
Used in conjunction with the
.B \-C
option, this will limit the number
of files created to the specified number, and begin overwriting files
from the beginning, thus creating a 'rotating' buffer.
In addition, it will name
the files with enough leading 0s to support the maximum number of
files, allowing them to sort correctly.
.IP
Used in conjunction with the
.B \-G
option, this will limit the number of rotated dump files that get
created, exiting with status 0 when reaching the limit.
.IP
If used in conjunction with both
.B \-C
and
.B \-G,
the
.B \-W
option will currently be ignored, and will only affect the file name.
.TP
.B \-x
When parsing and printing,
in addition to printing the headers of each packet, print the data of
each packet (minus its link level header) in hex.
The smaller of the entire packet or
.I snaplen
bytes will be printed. Note that this is the entire link-layer
packet, so for link layers that pad (e.g. Ethernet), the padding bytes
will also be printed when the higher layer packet is shorter than the
required padding.
In the current implementation this flag may have the same effect as
.B \-xx
if the packet is truncated.
.TP
.B \-xx
When parsing and printing,
in addition to printing the headers of each packet, print the data of
each packet,
.I including
its link level header, in hex.
.TP
.B \-X
When parsing and printing,
in addition to printing the headers of each packet, print the data of
each packet (minus its link level header) in hex and ASCII.
This is very handy for analysing new protocols.
In the current implementation this flag may have the same effect as
.B \-XX
if the packet is truncated.

.BR -d )
to \fIdatalinktype\fP.
.TP
.BI \-z " postrotate-command"
Used in conjunction with the
.B -C
or
.B -G
options, this will make
.I tcpdump
run "
.I postrotate-command file
" where
.I file
is the savefile being closed after each rotation. For example, specifying
.B \-z gzip
or
.B \-z bzip2
will compress each savefile using gzip or bzip2.
.IP
Note that tcpdump will run the command in parallel to the capture, using
the lowest priority so that this doesn't disturb the capture process.
.IP
And in case you would like to use a command that itself takes flags or
different arguments, you can always write a shell script that will take the
savefile name as the only argument, make the flags & arguments arrangements
and execute the command that you want.

.BI \-Z " user"

.IR user .
.IP
This behavior can also be enabled by default at compile time.
.IP "\fI expression\fP"

.LP
For the \fIexpression\fP syntax, see
.BR \%pcap-filter (@MAN_MISC_INFO@).
.LP
The \fIexpression\fP argument can be passed to \fItcpdump\fP as either a single
Shell argument, or as multiple Shell arguments, whichever is more convenient.
Generally, if the expression contains Shell metacharacters, such as
backslashes used to escape protocol names, it is easier to pass it as
a single, quoted argument rather than to escape the Shell
metacharacters.
Multiple arguments are concatenated with spaces before being parsed.

The timestamp reflects the time the kernel applied a time stamp to the packet.
No attempt is made to account for the time lag between when the network

kernel applied a time stamp to the packet; that time lag could include a
delay between the time when the network interface finished receiving a
packet from the network and the time when an interrupt was delivered to

.LP
If the '-e' option is given, the link level header is printed out.
On Ethernets, the source and destination addresses, protocol,
and packet length are printed.
.LP
On FDDI networks, the '-e' option causes \fItcpdump\fP to print
the `frame control' field, the source and destination addresses,
and the packet length.
(The `frame control' field governs the
interpretation of the rest of the packet.
Normal packets (such
as those containing IP datagrams) are `async' packets, with a priority
value between 0 and 7; for example, `\fBasync4\fR'.
Such packets
are assumed to contain an 802.2 Logical Link Control (LLC) packet;
the LLC header is printed if it is \fInot\fR an ISO datagram or a
so-called SNAP packet.
.LP
On Token Ring networks, the '-e' option causes \fItcpdump\fP to print
the `access control' and `frame control' fields, the source and
destination addresses, and the packet length.
As on FDDI networks,
packets are assumed to contain an LLC packet.
Regardless of whether
the '-e' option is specified or not, the source routing information is
printed for source-routed packets.
.LP
On 802.11 networks, the '-e' option causes \fItcpdump\fP to print
the `frame control' fields, all of the addresses in the 802.11 header,

\fI(N.B.: The following description assumes familiarity with
the SLIP compression algorithm described in RFC 1144.)\fP

On SLIP links, a direction indicator (``I'' for inbound, ``O'' for outbound),
packet type, and compression information are printed out.
The packet type is printed first.
The three types are \fIip\fP, \fIutcp\fP, and \fIctcp\fP.
No further link information is printed for \fIip\fR packets.
For TCP packets, the connection identifier is printed following the type.
If the packet is compressed, its encoded header is printed out.
The special cases are printed out as
\fB*S+\fIn\fR and \fB*SA+\fIn\fR, where \fIn\fR is the amount by which
the sequence number (or sequence number and ack) has changed.
If it is not a special case,
zero or more changes are printed.
A change is indicated by U (urgent pointer), W (window), A (ack),
S (sequence number), and I (packet ID), followed by a delta (+n or -n),
or a new value (=n).
Finally, the amount of data in the packet and compressed header length
are printed.

For example, the following line shows an outbound compressed TCP packet,

The first line says that TCP port 1023 on rtsg sent a packet
to port \fIlogin\fP
on csam.
The \fBS\fP indicates that the \fISYN\fP flag was set.
The packet sequence number was 768512 and it contained no data.
(The notation is `first:last' which means `sequence
numbers \fIfirst\fP
up to but not including \fIlast\fP'.)
There was no piggy-backed ACK, the available receive window was 4096
bytes and there was a max-segment-size option requesting an MSS of
1024 bytes.
.LP
Csam replies with a similar packet except it includes a piggy-backed
ACK for rtsg's SYN.
Rtsg then ACKs csam's SYN.
The `.' means the ACK flag was set.
The packet contained no data so there is no data sequence number or length.
Note that the ACK sequence
number is a small integer (1).
The first time \fItcpdump\fP sees a
TCP `conversation', it prints the sequence number from the packet.
On subsequent packets of the conversation, the difference between
the current packet's sequence number and this initial sequence number
is printed.
This means that sequence numbers after the
first can be interpreted
as relative byte positions in the conversation's data stream (with the
first data byte each direction being `1').
`-S' will override this
feature, causing the original sequence numbers to be output.
.LP
On the 6th line, rtsg sends csam 19 bytes of data (bytes 2 through 20
in the rtsg \(-> csam side of the conversation).
The PSH flag is set in the packet.
On the 7th line, csam says it's received data sent by rtsg up to
but not including byte 21.
Most of this data is apparently sitting in the
socket buffer since csam's receive window has gotten 19 bytes smaller.
Csam also sends one byte of data to rtsg in this packet.
On the 8th and 9th lines,
csam sends two bytes of urgent, pushed data to rtsg.
.LP
If the snapshot was small enough that \fItcpdump\fP didn't capture
the full TCP header, it interprets as much of the header as it can
and then reports ``[|\fItcp\fP]'' to indicate the remainder could not
be interpreted.
If the header contains a bogus option (one with a length
that's either too small or beyond the end of the header), \fItcpdump\fP
reports it as ``[\fIbad opt\fP]'' and does not interpret any further
options (since it's impossible to tell where they start).
If the header
length indicates options are present but the IP datagram length is not
long enough for the options to actually be there, \fItcpdump\fP reports
it as ``[\fIbad hdr length\fP]''.

Now we're interested in capturing packets that have only the

Note that we don't want packets from step 2

What we need is a correct filter
expression for \fItcpdump\fP.

Recall the structure of a TCP header without options:

.PP
A TCP header usually holds 20 octets of data, unless options are
present.
The first line of the graph contains octets 0 - 3, the
second line shows octets 4 - 7 etc.
.PP
Starting to count with 0, the relevant TCP control bits are contained
in octet 13:
.PP
.nf
0 7| 15| 23| 31

| HL | rsvd |C|E|U|A|P|R|S|F| window size |

Let's have a closer look at octet no. 13:
.PP
.nf
| |
|---------------|
|C|E|U|A|P|R|S|F|
|---------------|
|7 5 3 0|
.fi
.PP
These are the TCP control bits we are interested
in.
We have numbered the bits in this octet from 0 to 7, right to
left, so the PSH bit is bit number 3, while the URG bit is number 5.
.PP
Recall that we want to capture packets with only SYN set.
Let's see what happens to octet 13 if a TCP datagram arrives
with the SYN bit set in its header:
.PP
.nf
|C|E|U|A|P|R|S|F|
|---------------|
|0 0 0 0 0 0 1 0|
|---------------|
|7 6 5 4 3 2 1 0|
.fi
.PP
Looking at the
control bits section we see that only bit number 1 (SYN) is set.
.PP
Assuming that octet number 13 is an 8-bit unsigned integer in
network byte order, the binary value of this octet is
.IP
00000010
.PP
and its decimal representation is
.PP
.nf
7 6 5 4 3 2 1 0
0*2 + 0*2 + 0*2 + 0*2 + 0*2 + 0*2 + 1*2 + 0*2 = 2
.fi
.PP
We're almost done, because now we know that if only SYN is set,
the value of the 13th octet in the TCP header, when interpreted
as a 8-bit unsigned integer in network byte order, must be exactly 2.
.PP
This relationship can be expressed as
.RS
.B
tcp[13] == 2
.RE
.PP
We can use this expression as the filter for \fItcpdump\fP in order
to watch packets which have only SYN set:
.RS
.B
-tcpdump -i xl0 tcp[13] == 2
+tcpdump -i xl0 'tcp[13] == 2'
.RE
.PP
The expression says "let the 13th octet of a TCP datagram have
the decimal value 2", which is exactly what we want.
.PP
Now, let's assume that we need to capture SYN packets, but we
don't care if ACK or any other TCP control bit is set at the
same time.
Let's see what happens to octet 13 when a TCP datagram
with SYN-ACK set arrives:
.PP
.nf
|C|E|U|A|P|R|S|F|
|---------------|
|0 0 0 1 0 0 1 0|
|---------------|
|7 6 5 4 3 2 1 0|
.fi
.PP
Now bits 1 and 4 are set in the 13th octet.
The binary value of
octet 13 is
.IP
00010010
.PP
which translates to decimal
.PP
.nf
7 6 5 4 3 2 1 0
0*2 + 0*2 + 0*2 + 1*2 + 0*2 + 0*2 + 1*2 + 0*2 = 18
.fi
.PP
Now we can't just use 'tcp[13] == 18' in the \fItcpdump\fP filter
expression, because that would select only those packets that have
SYN-ACK set, but not those with only SYN set.
Remember that we don't care
if ACK or any other control bit is set as long as SYN is set.
.PP
In order to achieve our goal, we need to logically AND the
binary value of octet 13 with some other value to preserve
the SYN bit.
We know that we want SYN to be set in any case,
so we'll logically AND the value in the 13th octet with
the binary value of a SYN:
.PP
.nf
00010010 SYN-ACK 00000010 SYN
AND 00000010 (we want SYN) AND 00000010 (we want SYN)
-------- --------
= 00000010 = 00000010
.fi
.PP
We see that this AND operation delivers the same result
regardless whether ACK or another TCP control bit is set.
The decimal representation of the AND value as well as
the result of this operation is 2 (binary 00000010),
so we know that for packets with SYN set the following
relation must hold true:
.IP
( ( value of octet 13 ) AND ( 2 ) ) == ( 2 )
.PP
This points us to the \fItcpdump\fP filter expression

.RE
Jssmag.209 initiates transaction id 12266 with host helios by requesting
up to 8 packets (the `<0-7>').
The hex number at the end of the line
is the value of the `userdata' field in the request.
.LP
Helios responds with 8 512-byte packets.
The `:digit' following the
transaction id gives the packet sequence number in the transaction
and the number in parens is the amount of data in the packet,
excluding the ATP header.
The `*' on packet 7 indicates that the
EOM bit was set.
.LP
Jssmag.209 then requests that packets 3 & 5 be retransmitted.
Helios
resends them then jssmag.209 releases the transaction.
Finally,
jssmag.209 initiates the next request.
The `*' on the request
indicates that XO (`exactly once') was \fInot\fP set.

NIT doesn't let you watch your own outbound traffic, BPF will.
We recommend that you use the latter.
.LP
-On Linux systems with 2.0[.x] kernels:
-.IP
-packets on the loopback device will be seen twice;
-.IP
-packet filtering cannot be done in the kernel, so that all packets must
-be copied from the kernel in order to be filtered in user mode;
-.IP
-all of a packet, not just the part that's within the snapshot length,
-will be copied from the kernel (the 2.0[.x] packet capture mechanism, if
-asked to copy only part of a packet to userspace, will not report the
-true length of the packet; this would cause most IP packets to get an
-error from
-.BR tcpdump );
-.IP
-capturing on some PPP devices won't work correctly.
-.LP
-We recommend that you upgrade to a 2.2 or later kernel.
-.LP
Some attempt should be made to reassemble IP fragments or, at least
to compute the right length for the higher level protocol.
.LP
Name server inverse queries are not dumped correctly: the (empty)
question section is printed rather than real query in the answer
section.
Some believe that inverse queries are themselves a bug and
prefer to fix the program generating them rather than \fItcpdump\fP.
.LP
A packet trace that crosses a daylight savings time change will give
skewed time stamps (the time change is ignored).
.LP
Filter expressions on fields other than those in Token Ring headers will
not correctly handle source-routed Token Ring packets.
.LP
Filter expressions on fields other than those in 802.11 headers will not
correctly handle 802.11 data packets with both To DS and From DS set.
.LP
.BR "ip6 proto"
should chase header chain, but at this moment it does not.
.BR "ip6 protochain"
is supplied for this behavior.
.LP
Arithmetic expression against transport layer headers, like \fBtcp[0]\fP,
does not work against IPv6 packets.
It only looks at IPv4 packets.

/*
* Ensure that, on a dump file's descriptor, we have all the rights
* necessary to make the standard I/O library work with an fdopen()ed
* FILE * from that descriptor.
*
* A long time ago in a galaxy far, far away, AT&T decided that, instead
* of providing separate APIs for getting and setting the FD_ flags on a
* descriptor, getting and setting the O_ flags on a descriptor, and
* locking files, they'd throw them all into a kitchen-sink fcntl() call
* along the lines of ioctl(), the fact that ioctl() operations are
* largely specific to particular character devices but fcntl() operations
* are either generic to all descriptors or generic to all descriptors for
- * regular files nonwithstanding.
+ * regular files notwithstanding.
*
* The Capsicum people decided that fine-grained control of descriptor
* operations was required, so that you need to grant permission for
* reading, writing, seeking, and fcntl-ing. The latter, courtesy of
* AT&T's decision, means that "fcntl-ing" isn't a thing, but a motley
* collection of things, so there are *individual* fcntls for which
* permission needs to be granted.
*
* The FreeBSD standard I/O people implemented some optimizations that
* requires that the standard I/O routines be able to determine whether
* the descriptor for the FILE * is open append-only or not; as that
* descriptor could have come from an open() rather than an fopen(),
* that requires that it be able to do an F_GETFL fcntl() to read
* the O_ flags.
*
* Tcpdump uses ftell() to determine how much data has been written
* to a file in order to, when used with -C, determine when it's time
* to rotate capture files. ftell() therefore needs to do an lseek()
* to find out the file offset and must, thanks to the aforementioned
* optimization, also know whether the descriptor is open append-only
* or not.
*
* The net result of all the above is that we need to grant CAP_SEEK,
* CAP_WRITE, and CAP_FCNTL with the CAP_FCNTL_GETFL subcapability.
*
* Perhaps this is the universe's way of saying that either
*
* 1) there needs to be an fopenat() call and a pcap_dump_openat() call
* using it, so that Capsicum-capable tcpdump wouldn't need to do
* an fdopen()
*
* or
*
* 2) there needs to be a cap_fdopen() call in the FreeBSD standard
* I/O library that knows what rights are needed by the standard
* I/O library, based on the open mode, and assigns them, perhaps
* with an additional argument indicating, for example, whether
* seeking should be allowed, so that tcpdump doesn't need to know
* what the standard I/O library happens to require this week.
