The configure +script will determine your system attributes and generate an +appropriate Makefile from Makefile.in. Next run "make". If everything +goes well you can su to root and run "make install". However, you need +not install libpcap if you just want to build tcpdump; just make sure +the tcpdump and libpcap directory trees have the same parent +directory. + +If configure says: + + configure: warning: cannot determine packet capture interface + configure: warning: (see INSTALL for more info) + +then your system either does not support packet capture or your system +does support packet capture but libpcap does not support that +particular type. (If you have HP-UX, see below.) If your system uses a +packet capture not supported by libpcap, please send us patches; don't +forget to include an autoconf fragment suitable for use in +configure.ac. + +It is possible to override the default packet capture type, although +the circumstance where this works are limited. For example if you have +installed bpf under SunOS 4 and wish to build a snit libpcap: + + ./configure --with-pcap=snit + +Another example is to force a supported packet capture type in the case +where the configure scripts fails to detect it. + +You will need an ANSI C compiler to build libpcap. The configure script +will abort if your compiler is not ANSI compliant. If this happens, use +the generally available GNU C compiler (GCC). + +You will need either Flex 2.5.31 or later, or a version of Lex +compatible with it (if any exist), to build libpcap. The configure +script will abort if there isn't any such program. If you have an older +version of Flex, or don't have a compatible version of Lex, the current +version of flex is available at flex.sourceforge.net. + +You will need either Bison, Berkeley YACC, or a version of YACC +compatible with them (if any exist), to build libpcap. The configure +script will abort if there isn't any such program. If you don't have +any such program, the current version of Bison can be found at +http://ftp.gnu.org/gnu/bison/ and the current version of Berkeley YACC +can be found at http://invisible-island.net/byacc/. + +Sometimes the stock C compiler does not interact well with Flex and +Bison. The list of problems includes undefined references for alloca. +You can get around this by installing GCC. + +If you use Solaris, there is a bug with bufmod(7) that is fixed in +Solaris 2.3.2 (aka SunOS 5.3.2). Setting a snapshot length with the +broken bufmod(7) results in data be truncated from the FRONT of the +packet instead of the end. The work around is to not set a snapshot +length but this results in performance problems since the entire packet +is copied to user space. If you must run an older version of Solaris, +there is a patch available from Sun; ask for bugid 1149065. After +installing the patch, use "setenv BUFMOD_FIXED" to enable use of +bufmod(7). However, we recommend you run a more current release of +Solaris. + +If you use the SPARCompiler, you must be careful to not use the +/usr/ucb/cc interface. If you do, you will get bogus warnings and +perhaps errors. Either make sure your path has /opt/SUNWspro/bin +before /usr/ucb or else: + + setenv CC /opt/SUNWspro/bin/cc + +before running configure. (You might have to do a "make distclean" +if you already ran configure once). + +If you are trying to do packet capture with a FORE ATM card, you may or +may not be able to. They usually only release their driver in object +code so unless their driver supports packet capture, there's not much +libpcap can do. + +If you get an error like: + + tcpdump: recv_ack: bind error 0x??? + +when using DLPI, look for the DL_ERROR_ACK error return values, usually +in /usr/include/sys/dlpi.h, and find the corresponding value. + +Under {DEC OSF/1, Digital UNIX, Tru64 UNIX}, packet capture must be +enabled before it can be used. For instructions on how to enable packet +filter support, see: + + ftp://ftp.digital.com/pub/Digital/dec-faq/Digital-UNIX + +Look for the "How do I configure the Berkeley Packet Filter and capture +tcpdump traces?" item. + +Once you enable packet filter support, your OSF system will support bpf +natively. + +Under Ultrix, packet capture must be enabled before it can be used. For +instructions on how to enable packet filter support, see: + + ftp://ftp.digital.com/pub/Digital/dec-faq/ultrix + +If you use HP-UX, you must have at least version 9 and either the +version of cc that supports ANSI C (cc -Aa) or else use the GNU C +compiler. You must also buy the optional streams package. If you don't +have: + + /usr/include/sys/dlpi.h + /usr/include/sys/dlpi_ext.h + +then you don't have the streams package. In addition, we believe you +need to install the "9.X LAN and DLPI drivers cumulative" patch +(PHNE_6855) to make the version 9 DLPI work with libpcap. + +The DLPI streams package is standard starting with HP-UX 10. + +The HP implementation of DLPI is a little bit eccentric. Unlike +Solaris, you must attach /dev/dlpi instead of the specific /dev/* +network pseudo device entry in order to capture packets. The PPA is +based on the ifnet "index" number. Under HP-UX 9, it is necessary to +read /dev/kmem and the kernel symbol file (/hp-ux). Under HP-UX 10, +DLPI can provide information for determining the PPA. It does not seem +to be possible to trace the loopback interface. Unlike other DLPI +implementations, PHYS implies MULTI and SAP and you get an error if you +try to enable more than one promiscuous mode at a time. + +It is impossible to capture outbound packets on HP-UX 9. To do so on +HP-UX 10, you will, apparently, need a late "LAN products cumulative +patch" (at one point, it was claimed that this would be PHNE_18173 for +s700/10.20; at another point, it was claimed that the required patches +were PHNE_20892, PHNE_20725 and PHCO_10947, or newer patches), and to do +so on HP-UX 11 you will, apparently, need the latest lancommon/DLPI +patches and the latest driver patch for the interface(s) in use on HP-UX +11 (at one point, it was claimed that patches PHNE_19766, PHNE_19826, +PHNE_20008, and PHNE_20735 did the trick). + +Furthermore, on HP-UX 10, you will need to turn on a kernel switch by +doing + + echo 'lanc_outbound_promisc_flag/W 1' | adb -w /stand/vmunix /dev/mem + +You would have to arrange that this happen on reboots; the right way to +do that would probably be to put it into an executable script file +"/sbin/init.d/outbound_promisc" and making +"/sbin/rc2.d/S350outbound_promisc" a symbolic link to that script. + +Finally, testing shows that there can't be more than one simultaneous +DLPI user per network interface. + +If you use Linux, this version of libpcap is known to compile and run +under Red Hat 4.0 with the 2.0.25 kernel. It may work with earlier 2.X +versions but is guaranteed not to work with 1.X kernels. Running more +than one libpcap program at a time, on a system with a 2.0.X kernel, can +cause problems since promiscuous mode is implemented by twiddling the +interface flags from the libpcap application; the packet capture +mechanism in the 2.2 and later kernels doesn't have this problem. Also, +packet timestamps aren't very good. This appears to be due to haphazard +handling of the timestamp in the kernel. + +Note well: there is rumoured to be a version of tcpdump floating around +called 3.0.3 that includes libpcap and is supposed to support Linux. +You should be advised that neither the Network Research Group at LBNL +nor the Tcpdump Group ever generated a release with this version number. +The LBNL Network Research Group notes with interest that a standard +cracker trick to get people to install trojans is to distribute bogus +packages that have a version number higher than the current release. +They also noted with annoyance that 90% of the Linux related bug reports +they got are due to changes made to unofficial versions of their page. +If you are having trouble but aren't using a version that came from +tcpdump.org, please try that before submitting a bug report! + +On Linux, libpcap will not work if the kernel does not have the packet +socket option enabled; see the README.linux file for information about +this. + +If you use AIX, you may not be able to build libpcap from this release. +We do not have an AIX system in house so it's impossible for us to test +AIX patches submitted to us. We are told that you must link against +/lib/pse.exp, that you must use AIX cc or a GNU C compiler newer than +2.7.2, and that you may need to run strload before running a libpcap +application. + +Read the README.aix file for information on installing libpcap and +configuring your system to be able to support libpcap. + +If you use NeXTSTEP, you will not be able to build libpcap from this +release. + +If you use SINIX, you should be able to build libpcap from this +release. It is known to compile and run on SINIX-Y/N 5.42 with the C-DS +V1.0 or V1.1 compiler. But note that in some releases of SINIX, yacc +emits incorrect code; if grammar.y fails to compile, change every +occurence of: + + #ifdef YYDEBUG + +to: + #if YYDEBUG + +Another workaround is to use flex and bison. + +If you use SCO, you might have trouble building libpcap from this +release. We do not have a machine running SCO and have not had reports +of anyone successfully building on it; the current release of libpcap +does not compile on SCO OpenServer 5. Although SCO apparently supports +DLPI to some extent, the DLPI in OpenServer 5 is very non-standard, and +it appears that completely new code would need to be written to capture +network traffic. SCO do not appear to provide tcpdump binaries for +OpenServer 5 or OpenServer 6 as part of SCO Skunkware: + + http://www.sco.com/skunkware/ + +If you use UnixWare, you might be able to build libpcap from this +release, or you might not. We do not have a machine running UnixWare, +so we have not tested it; however, SCO provide packages for libpcap +0.6.2 and tcpdump 3.7.1 in the UnixWare 7/Open UNIX 8 part of SCO +Skunkware, and the source package for libpcap 0.6.2 is not changed from +the libpcap 0.6.2 source release, so this release of libpcap might also +build without changes on UnixWare 7. + +If linking tcpdump fails with "Undefined: _alloca" when using bison on +a Sun4, your version of Bison is broken. In any case version 1.16 or +higher is recommended (1.14 is known to cause problems 1.16 is known to +work). Either pick up a current version from: + + http://ftp.gnu.org/gnu/bison/ + +or hack around it by inserting the lines: + + #ifdef __GNUC__ + #define alloca __builtin_alloca + #else + #ifdef sparc + #include + #else + char *alloca (); + #endif + #endif + +right after the (100 line!) GNU license comment in bison.simple, remove +grammar.[co] and fire up make again. + +If you use SunOS 4, your kernel must support streams NIT. If you run a +libpcap program and it dies with: + + /dev/nit: No such device + +You must add streams NIT support to your kernel configuration, run +config and boot the new kernel. + +FILES +----- +CHANGES -

Applications include +network statistics collection, security monitoring, network debugging, +etc. Since almost every system vendor provides a different interface +for packet capture, and since we've developed several tools that +require this functionality, we've created this system-independent API +to ease in porting and to alleviate the need for several +system-dependent packet capture modules in each application. + +For some platforms there are README.{system} files that discuss issues +with the OS's interface for packet capture on those platforms, such as +how to enable support for that interface in the OS, if it's not built in +by default. + +The libpcap interface supports a filtering mechanism based on the +architecture in the BSD packet filter. BPF is described in the 1993 +Winter Usenix paper ``The BSD Packet Filter: A New Architecture for +User-level Packet Capture''.

Ideally, libpcap +would translate BPF filters into a filter program that is compatible +with the underlying kernel subsystem, but this is not yet implemented. + +BPF is standard in 4.4BSD, BSD/OS, NetBSD, FreeBSD, OpenBSD, DragonFly +BSD, and macOS; an older, modified and undocumented version is standard +in AIX. {DEC OSF/1, Digital UNIX, Tru64 UNIX} uses the packetfilter +interface but has been extended to accept BPF filters (which libpcap +utilizes).

These targets are +supported: + + - Borland C 4.0+ small or large model. + - Metaware HighC 3.1+ with PharLap DOS-extender + - GNU C 2.7+ with djgpp 2.01+ DOS extender + - Watcom C 11.x with DOS4GW extender + +Note: the files in the libpcap.zip contains short truncated filenames. + So for djgpp to work with these, disable the use of long file names by + setting "LFN=n" in the environment. On the other hand, if you get libpcap + from Github or the official libpcap.tar.gz, some filenames are beyond 8+3. + In this case set "LFN=y". + +Files specific to DOS are pcap-dos.[ch] and the assembly and C files in +the MSDOS sub-directory. Remember to built the libpcap library from the top +install directory. And not from the MSDOS sub-directory. + +Note for djgpp users: + If you got the libpcap from the official site www.tcpdump, then that + distribution does NOT contain any sources for building 32-bit drivers. + Instead get the full version at + http://www.watt-32.net/pcap/libpcap.zip + + and set "USE_32BIT_DRIVERS = 1" in msdos\common.dj. + + + +Requirements +------------ + +DOS-libpcap currently only works reliably with a real-mode Ethernet packet- +driver. This driver must be installed prior to using any program (e.g. +tcpdump) compiled with libpcap. Work is underway to implement protected- +mode drivers for 32-bit targets (djgpp only). The 3Com 3c509 driver is +working almost perfectly. Due to lack of LAN-cards, I've not had the +opportunity to test other drivers. These 32-bit drivers are modified +Linux drivers. + + +Required packages +----------------- + +The following packages and tools must be present for all targets. + +1. Watt-32 tcp/ip library. This library is *not* used to send or + receive network data. It's mostly used to access the 'hosts' + file and other features. Get 'watt32s*.zip' at: + + http://www.watt-32.net + +2. Exception handler and disassember library (libexc.a) is needed if + "USE_EXCEPT = 1" in common.dj. Available at: + + http://www.watt-32.net/misc/exc_dx07.zip + +3. Flex & Bison is used to generate parser for the filter handler + pcap_compile: + ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/flx254b.zip + ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/bsn241b.zip + +4. NASM assembler v 0.98 or later is required when building djgpp and + Watcom targets: + http://www.nasm.us/ + +5. sed (Stream Editor) is required for doing `make depend'. + It's available at: + ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/sed422b.zip + + A touch tool to update the time-stamp of a file. E.g.: + ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/grep29b.zip + +6. For djgpp rm.exe and cp.exe are required. These should already be + part of your djgpp installation. Also required (experimental at the + time) for djgpp is DLX 2.91 or later. This tool is for the generation + of dynamically loadable modules. + + +Compiling libpcap +----------------- + +Follow these steps in building libpcap: + +1. Make sure you've installed Watt-32 properly (see it's `INSTALL' file). + During that installation a environment variable `WATT_ROOT' is set. + This variable is used for building libpcap also (`WATT_INC' is + deducted from `WATT_ROOT'). djgpp users should also define environment + variables `C_INCLUDE_PATH' and `LIBRARY_PATH' to point to the include + directory and library directory respectively. E.g. put this in your + AUTOEXEC.BAT: + set C_INCLUDE_PATH=c:/net/watt/inc + set LIBRARY_PATH=c:/net/watt/lib + +2. Revise the msdos/common.dj file for your djgpp/gcc installation; + - change the value of `GCCLIB' to match location of libgcc.a. + - set `USE_32BIT_DRIVERS = 1' to build 32-bit driver objects. + + +3. Build pcap by using appropriate makefile. For djgpp, use: + `make -f msdos/makefile.dj' (i.e. GNU `make') + + For a Watcom target say: + `wmake -f msdos\makefile.wc' + + For a Borland target say: + `maker -f msdos\Makefile pcap_bc.lib' (Borland's `maker.exe') + + And for a HighC/Pharlap target say: + `maker -f msdos\Makefile pcap_hc.lib' (Borland's `maker.exe') + + You might like to change some `CFLAGS' -- only `DEBUG' define currently + have any effect. It shows a rotating "fan" in upper right corner of + screen. Remove `DEBUG' if you don't like it. You could add + `-fomit-frame-pointer' to `CFLAGS' to speed up the generated code. + But note, this makes debugging and crash-traceback difficult. Only + add it if you're fully confident your application is 100% stable. + + Note: Code in `USE_NDIS2' does not work at the moment. + +4. The resulting library is put in current directory. There's some + test-program for `libpcap': `filtertest.exe', `findalldevstest.exe', + `nonblocktest.exe' and `opentest.exe'. + + But linking the library with `tcpdump' is the ultimate test. DOS/djgpp + should now hopefully be a supported target. Get the sources at: + https://www.tcpdump.org/ + or + https://github.com/the-tcpdump-group/tcpdump/ + + (click on the 'Download ZIP' on the right side of that page.) + + +Extensions to libpcap +--------------------- + +I've included some extra functions to DOS-libpcap: + + `pcap_config_hook (const char *keyword, const char *value)' : + + Allows an application to set values of internal libpcap variables. + `keyword' and an associated `value' should be present in the `debug_tab[]' + array in pcap-dos.c (currently only used to set debug-levels and parameters + for the 32-bit network drivers.) Thus an application using DOS-libpcap can + override the default value during it's configure process (see tcpdump's + msdos/config.c file for an extended example). + + `pcap_set_wait (pcap_t *, void (*)(void), int)' : + + Only effective when reading offline traffic from dump-files. + Function `pcap_offline_read()' will wait (and optionally yield) + before printing next packet. This will simulate the pace the packets + where actually recorded. + + + +Happy sniffing ! + + +Gisle Vanem + +October 1999, 2004, 2006, 2013 + Index: vendor/libpcap/1.9.1/msdos/makefile =================================================================== --- vendor/libpcap/1.9.1/msdos/makefile (nonexistent) +++ vendor/libpcap/1.9.1/msdos/makefile (revision 353142) @@ -0,0 +1,180 @@ +# +# Makefile for dos-libpcap.

FDDI headers contain Ethernet-like source +and destination addresses, and often contain Ethernet-like packet +types, so you can filter on these FDDI fields just as with the +analogous Ethernet fields. +FDDI headers also contain other fields, +but you cannot name them explicitly in a filter expression. +.LP +Similarly, `tr' and `wlan' are aliases for `ether'; the previous +paragraph's statements about FDDI headers also apply to Token Ring +and 802.11 wireless LAN headers.

on all other systems, if +those operators are used, filtering will be done in user mode, which +will increase the overhead of capturing packets and may cause more +packets to be dropped. +.IP +To access data inside the packet, use the following syntax: +.in +.5i +.nf +\fIproto\fB [ \fIexpr\fB : \fIsize\fB ]\fR +.fi +.in -.5i +\fIProto\fR is one of \fBether, fddi, tr, wlan, ppp, slip, link, +ip, arp, rarp, tcp, udp, icmp, ip6\fR or \fBradio\fR, and +indicates the protocol layer for the index operation. +(\fBether, fddi, wlan, tr, ppp, slip\fR and \fBlink\fR all refer to the +link layer. \fBradio\fR refers to the "radio header" added to some +802.11 captures.) +Note that \fItcp, udp\fR and other upper-layer protocol types only +apply to IPv4, not IPv6 (this will be fixed in the future). +The byte offset, relative to the indicated protocol layer, is +given by \fIexpr\fR. +\fISize\fR is optional and indicates the number of bytes in the +field of interest; it can be either one, two, or four, and defaults to one. +The length operator, indicated by the keyword \fBlen\fP, gives the +length of the packet. + +For example, `\fBether[0] & 1 != 0\fP' catches all multicast traffic. +The expression `\fBip[0] & 0xf != 5\fP' +catches all IPv4 packets with options. +The expression +`\fBip[6:2] & 0x1fff = 0\fP' +catches only unfragmented IPv4 datagrams and frag zero of fragmented +IPv4 datagrams. +This check is implicitly applied to the \fBtcp\fP and \fBudp\fP +index operations. +For instance, \fBtcp[0]\fP always means the first +byte of the TCP \fIheader\fP, and never means the first byte of an +intervening fragment. + +Some offsets and field values may be expressed as names rather than +as numeric values. +The following protocol header field offsets are +available: \fBicmptype\fP (ICMP type field), \fBicmp6type (ICMP v6 type field) +\fBicmpcode\fP (ICMP code field), \fBicmp6code\fP (ICMP v6 code field), and +\fBtcpflags\fP (TCP flags field). + +The following ICMP type field values are available: \fBicmp-echoreply\fP, +\fBicmp-unreach\fP, \fBicmp-sourcequench\fP, \fBicmp-redirect\fP, +\fBicmp-echo\fP, \fBicmp-routeradvert\fP, \fBicmp-routersolicit\fP, +\fBicmp-timxceed\fP, \fBicmp-paramprob\fP, \fBicmp-tstamp\fP, +\fBicmp-tstampreply\fP, \fBicmp-ireq\fP, \fBicmp-ireqreply\fP, +\fBicmp-maskreq\fP, \fBicmp-maskreply\fP. + +The following ICMPv6 type fields are available: \fBicmp6-echo\fP, +\fBicmp6-echoreply\fP, \fBicmp6-multicastlistenerquery\fP, +\fBicmp6-multicastlistenerreportv1\fP, \fBicmp6-multicastlistenerdone\fP, +\fBicmp6-routersolicit\fP, \fBicmp6-routeradvert\fP, +\fBicmp6-neighborsolicit\fP, \fBicmp6-neighboradvert\fP, \fBicmp6-redirect\fP, +\fBicmp6-routerrenum\fP, \fBicmp6-nodeinformationquery\fP, +\fBicmp6-nodeinformationresponse\fP, \fBicmp6-ineighbordiscoverysolicit\fP, +\fBicmp6-ineighbordiscoveryadvert\fP, \fBicmp6-multicastlistenerreportv2\fP, +\fBicmp6-homeagentdiscoveryrequest\fP, \fBicmp6-homeagentdiscoveryreply\fP, +\fBicmp6-mobileprefixsolicit\fP, \fBicmp6-mobileprefixadvert\fP, +\fBicmp6-certpathsolicit\fP, \fBicmp6-certpathadvert\fP, +\fBicmp6-multicastrouteradvert\fP, \fBicmp6-multicastroutersolicit\fP, +\fBicmp6-multicastrouterterm\fP. + +The following TCP flags field values are available: \fBtcp-fin\fP, +\fBtcp-syn\fP, \fBtcp-rst\fP, \fBtcp-push\fP, +\fBtcp-ack\fP, \fBtcp-urg\fP, \fBtcp-ece\fP, +\fBtcp-cwr\fP. +.LP +Primitives may be combined using: +.IP +A parenthesized group of primitives and operators. +.IP +Negation (`\fB!\fP' or `\fBnot\fP'). +.IP +Concatenation (`\fB&&\fP' or `\fBand\fP'). +.IP +Alternation (`\fB||\fP' or `\fBor\fP'). +.LP +Negation has highest precedence. +Alternation and concatenation have equal precedence and associate +left to right. +Note that explicit \fBand\fR tokens, not juxtaposition, +are now required for concatenation. +.LP +If an identifier is given without a keyword, the most recent keyword +is assumed. +For example, +.in +.5i +.nf +\fBnot host vs and ace\fR +.fi +.in -.5i +is short for +.in +.5i +.nf +\fBnot host vs and host ace\fR +.fi +.in -.5i +which should not be confused with +.in +.5i +.nf +\fBnot ( host vs or ace )\fR +.fi +.in -.5i +.SH EXAMPLES +.LP +To select all packets arriving at or departing from \fIsundown\fP: +.RS +.nf +\fBhost sundown\fP +.fi +.RE +.LP +To select traffic between \fIhelios\fR and either \fIhot\fR or \fIace\fR: +.RS +.nf +\fBhost helios and \\( hot or ace \\)\fP +.fi +.RE +.LP +To select all IP packets between \fIace\fR and any host except \fIhelios\fR: +.RS +.nf +\fBip host ace and not helios\fP +.fi +.RE +.LP +To select all traffic between local hosts and hosts at Berkeley: +.RS +.nf +.B +net ucb-ether +.fi +.RE +.LP +To select all ftp traffic through internet gateway \fIsnup\fP: +.RS +.nf +.B +gateway snup and (port ftp or ftp-data) +.fi +.RE +.LP +To select traffic neither sourced from nor destined for local hosts +(if you gateway to one other net, this stuff should never make it +onto your local net). +.RS +.nf +.B +ip and not net \fIlocalnet\fP +.fi +.RE +.LP +To select the start and end packets (the SYN and FIN packets) of each +TCP conversation that involves a non-local host. +.RS +.nf +.B +tcp[tcpflags] & (tcp-syn|tcp-fin) != 0 and not src and dst net \fIlocalnet\fP +.fi +.RE +.LP +To select all IPv4 HTTP packets to and from port 80, i.e. print only +packets that contain data, not, for example, SYN and FIN packets and +ACK-only packets.

This is not necessarily the type +of link-layer header that the packets being captured have on the network +from which they're being captured; for example, packets from an IEEE +802.11 network might be provided by libpcap with Ethernet headers that +the network adapter or the network adapter driver generates from the +802.11 headers. The names for those values begin with +.BR DLT_ , +so they are sometimes called "DLT_ values". +.PP +The values stored in the link-layer header type field in the savefile +header are, in most but not all cases, the same as the values returned +by +.BR pcap_datalink() . +The names for those values begin with +.BR LINKTYPE_ . +.PP +The link-layer header types supported by libpcap are described at +https://www.tcpdump.org/linktypes.html. +.SH SEE ALSO +pcap(3PCAP) Property changes on: vendor/libpcap/1.9.1/pcap-linktype.manmisc.in ___________________________________________________________________ Added: svn:eol-style ## -0,0 +1 ## +native \ No newline at end of property Added: svn:keywords ## -0,0 +1 ## +FreeBSD=%H \ No newline at end of property Added: svn:mime-type ## -0,0 +1 ## +text/plain \ No newline at end of property Index: vendor/libpcap/1.9.1/pcap-linux.c =================================================================== --- vendor/libpcap/1.9.1/pcap-linux.c (nonexistent) +++ vendor/libpcap/1.9.1/pcap-linux.c (revision 353142) @@ -0,0 +1,7534 @@ +/* + * pcap-linux.c: Packet capture interface to the Linux kernel + * + * Copyright (c) 2000 Torsten Landschoff + * Sebastian Krahmer + * + * License: BSD + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * + * 1.

It checks for multiple values in order to try + * to handle older rpcap daemons that sent the native OS's 'sockaddr_in' + * or 'sockaddr_in6' structures over the wire with some members + * byte-swapped, and to handle the fact that AF_INET6 has different + * values on different OSes. + * + * For IPv4 addresses, it converts the address family to host byte + * order from network byte order and puts it into the structure, + * sets the length if a sockaddr structure has a length, converts the + * port number to host byte order from network byte order and puts + * it into the structure, copies over the IPv4 address, and zeroes + * out the zero padding. + * + * For IPv6 addresses, it converts the address family to host byte + * order from network byte order and puts it into the structure, + * sets the length if a sockaddr structure has a length, converts the + * port number and flow information to host byte order from network + * byte order and puts them into the structure, copies over the IPv6 + * address, and converts the scope ID to host byte order from network + * byte order and puts it into the structure. + * + * The function will allocate the 'sockaddrout' variable according to the + * address family in use. In case the address does not belong to the + * AF_INET nor AF_INET6 families, 'sockaddrout' is not allocated and a + * NULL pointer is returned. This usually happens because that address + * does not exist on the other host, or is of an address family other + * than AF_INET or AF_INET6, so the RPCAP daemon sent a 'sockaddr_storage' + * structure containing all 'zero' values. + * + * Older RPCAPDs sent the addresses over the wire in the OS's native + * structure format. For most OSes, this looks like the over-the-wire + * format, but might have a different value for AF_INET6 than the value + * on the machine receiving the reply. For OSes with the newer BSD-style + * sockaddr structures, this has, instead of a 2-byte address family, + * a 1-byte structure length followed by a 1-byte address family. The + * RPCAPD code would put the address family in network byte order before + * sending it; that would set it to 0 on a little-endian machine, as + * htons() of any value between 1 and 255 would result in a value > 255, + * with its lower 8 bits zero, so putting that back into a 1-byte field + * would set it to 0. + * + * Therefore, for older RPCAPDs running on an OS with newer BSD-style + * sockaddr structures, the family field, if treated as a big-endian + * (network byte order) 16-bit field, would be: + * + * (length << 8) | family if sent by a big-endian machine + * (length << 8) if sent by a little-endian machine + * + * For current RPCAPDs, and for older RPCAPDs running on an OS with + * older BSD-style sockaddr structures, the family field, if treated + * as a big-endian 16-bit field, would just contain the family. + * + * \param sockaddrin: a 'rpcap_sockaddr' pointer to the variable that has + * to be de-serialized. + * + * \param sockaddrout: a 'sockaddr_storage' pointer to the variable that will contain + * the de-serialized data.

The format of the per-file header is: +.RS +.TS +box; +c s +c | c +c s. +Magic number +_ +Major version Minor version +_ +Time zone offset +_ +Time stamp accuracy +_ +Snapshot length +_ +Link-layer header type +.TE +.RE +.PP +All fields in the per-file header are in the byte order of the host +writing the file. Normally, the first field in the per-file header is a +4-byte magic number, with the value 0xa1b2c3d4. The magic number, when +read by a host with the same byte order as the host that wrote the file, +will have the value 0xa1b2c3d4, and, when read by a host with the +opposite byte order as the host that wrote the file, will have the value +0xd4c3b2a1. That allows software reading the file to determine whether +the byte order of the host that wrote the file is the same as the byte +order of the host on which the file is being read, and thus whether the +values in the per-file and per-packet headers need to be byte-swapped. +.PP +If the magic number has the value 0xa1b23c4d (with the two nibbles of +the two lower-order bytes of the magic number swapped), which would be +read as 0xa1b23c4d by a host with the same byte order as the host that +wrote the file and as 0x4d3cb2a1 by a host with the opposite byte order +as the host that wrote the file, the file format is the same as for +regular files, except that the time stamps for packets are given in +seconds and nanoseconds rather than seconds and microseconds. +.PP +Following this are: +.IP +A 2-byte file format major version number; the current version number is +2. +.IP +A 2-byte file format minor version number; the current version number is +4. +.IP +A 4-byte time zone offset; this is always 0. +.IP +A 4-byte number giving the accuracy of time stamps in the file; this is +always 0. +.IP +A 4-byte number giving the "snapshot length" of the capture; packets +longer than the snapshot length are truncated to the snapshot length, so +that, if the snapshot length is +.IR N , +only the first +.I N +bytes of a packet longer than +.I N +bytes will be saved in the capture. +.IP +a 4-byte number giving the link-layer header type for packets in the +capture; see +.BR pcap-linktype (@MAN_MISC_INFO@) +for the +.B LINKTYPE_ +values that can appear in this field. +.PP +Following the per-file header are zero or more packets; each packet +begins with a per-packet header, which is immediately followed by the +raw packet data. The format of the per-packet header is: +.RS +.TS +box; +c. +Time stamp, seconds value +_ +Time stamp, microseconds or nanoseconds value +_ +Length of captured packet data +_ +Un-truncated length of the packet data +.TE +.RE +.PP +All fields in the per-packet header are in the byte order of the host +writing the file. The per-packet header begins with a time stamp giving +the approximate time the packet was captured; the time stamp consists of +a 4-byte value, giving the time in seconds since January 1, 1970, +00:00:00 UTC, followed by a 4-byte value, giving the time in +microseconds or nanoseconds since that second, depending on the magic +number in the file header. Following that are a 4-byte value giving the +number of bytes of captured data that follow the per-packet header and a +4-byte value giving the number of bytes that would have been present had +the packet not been truncated by the snapshot length. The two lengths +will be equal if the number of bytes of packet data are less than or +equal to the snapshot length. +.SH SEE ALSO +pcap(3PCAP) Property changes on: vendor/libpcap/1.9.1/pcap-savefile.manfile.in ___________________________________________________________________ Added: svn:eol-style ## -0,0 +1 ## +native \ No newline at end of property Added: svn:keywords ## -0,0 +1 ## +FreeBSD=%H \ No newline at end of property Added: svn:mime-type ## -0,0 +1 ## +text/plain \ No newline at end of property Index: vendor/libpcap/1.9.1/pcap-septel.c =================================================================== --- vendor/libpcap/1.9.1/pcap-septel.c (nonexistent) +++ vendor/libpcap/1.9.1/pcap-septel.c (revision 353142) @@ -0,0 +1,354 @@ +/* + * pcap-septel.c: Packet capture interface for Intel/Septel card. + * + * Authors: Gilbert HOYEK (gil_hoyek@hotmail.com), Elias M.

Remote Monitoring LANs & WANs
+ (Design Notes for the SITA ACN device) + 		+ Fulko Hew
SITA INC Canada, Inc.
Revised: October 2, 2007 +
+ + +

SUMMARY

+
    + Note: This document is part of the libpcap Git and was derived from 'pcap.3' (circa Aug/07). +

    + The ACN provides a customized/distributed version of this library that alows SMPs to + interact with the various IOPs within the site providing a standard mechanism + to capture LAN and WAN message traffic. +

    +

    + + + + + + + + + +
    SMPThe Supervisory Management Processor where Wireshark (or equivalent) + runs in conjuction with a libpcap front-end.
    IOPI/O Processors where the monitored ports exist in conjunction + with a custom device driver/libpcap back-end.
    +
    +

    + Each IOP will be capable of supporting multiple connections from an SMP + enabling monitoring of more than one interface at a time, each through + its own seperate connection. The IOP is responsible to ensure and report + an error if any attempt is made to monitor the same interface more than once. +

    + There are three applications that will be supported by the ACN version of libpcap. + They each use a slightly different mode for looping/capturing and termination + as summarized in the following table: +

    +

    + + + + + + + + + + + + + + +
    Application Capture Termination
    wiresharkpcap_dispatch(all packets in one buffer of capture only)pcap_breakloop()
    tsharkpcap_dispatch(one buffer of capture only)Since a CTRL-C was used to terminate the application, pcap_breakloop() is never called.
    tcpdumppcap_loop(all packets in the next buffer, and loop forever)pcap_breakloop()
    +
    +

    + Note: In all cases, the termination of capturing is always (apparently) followed by + pcap_close(). Pcap_breakloop() is only used to stop/suspend looping/processing, + and upon close interpretation of the function definitions, it is possible to resume + capturing following a pcap_breakloop() without any re-initialization. +

    +

    ACN Limitations

    +
      +
    1. Monitoring of backup IOPs is not currently supported. +
    2. Ethernet interfaces cannot be monitored in promiscuous mode. +
    + +
+ +

ROUTINES

+
    + The following list of functions is the sub-set of Pcap functions that have been + altered/enhanced to support the ACN remote monitoring facility. The remainder of the Pcap + functions continue to perform their duties un-altered. Libpcap only supports this + mode of operation if it has been configured/compiled for SITA/ACN support. +

    +

      + pcap_findalldevs
      + pcap_freealldevs
      + pcap_open_live
      + pcap_close
      + pcap_setfilter
      + pcap_dispatch
      + pcap_loop
      + pcap_next
      + pcap_next_ex
      + pcap_stats
      +
    + + These subroutines have been modified for the ACN specific distributed and remote monitoring + ability perform the following basic functions. More detail is provided in the + "SMP/IOP Inter-Process Communication Protocol" section. +

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    pcap_open_live()Used to obtain a packet capture descriptor to look at packets on the network.
    + + + + + + +
    SMP -> IOP + The SMP will open a connection to the selected IOP on its 'sniffer' port + to ensure it is available. It sends a null terminated string identifying + the interface to be monitored. +
    IOP -> SMP + After any required processing is complete, the IOP will return a + null terminated string containing an error message if one occured. + If no error occured, a empty string is still returned. + Errors are: +
      +
    • "Interface (xxx) does not exist." +
    • "Interface (xxx) not configured." +
    • "Interface (xxx) already being monitored." +
    +
    pcap_findalldevs()It constructs a list of network devices that can be opened with pcap_open_live().
    + + + + + + + + + + + + + + + +
    SMP + It obtains a list of IOPs currently available (via /etc/hosts). +
    SMP -> IOP + The SMP will sequentially open a connection to each IOP on its 'sniffer' port to ensure + the IOP is available. + It sends a null terminated empty interface ID followed by the query request command. +
    IOP -> SMPThe IOP returns an error response and its list of devices. +
    SMP -> IOP + The SMP closes the TCP connection with each IOP. +
    SMP + The SMP adds the received information to its internal structure. +
    pcap_freealldevs()Used to free a list allocated by pcap_findalldevs().
    + + + +
    SMP + The SMP frees the structure it built as a result of the previous + invocation of pcap_findalldevs(). +
    pcap_dispatch()Used to collect and process packets.
    + + + + + + + + + + + + +
    SMP -> IOP + On the first invocation of pcap_dispatch(), pcap_loop(), or pcap_next(), or pcap_next_ex() following a pcap_open_live(), + the SMP will pass down the monitor start command and various parameters the IOP should use. +
    IOP -> SMP + The IOP now sends a stream of captured data. +
    SMP + The SMP will read the reverse channel of the connection between the SMP and the + IOP that provides the captured data (via 'p->read_op' which is 'pcap_read_linux()' + until the select() call returns a 'no more data' indication. + It will the process (at most) the next 'cnt' packets and invoke the specified + callback function for each packet processed. +
    IOP + The IOP continues to listen for additional commands as well as capturing and forwarding data to the SMP. +
    pcap_loop() + Is similar to pcap_dispatch() except it keeps reading packets until + the requested number of packets are processed or an error occurs. +
    + + + + + + + + + + + + +
    SMP -> IOP + On the first invocation of pcap_dispatch(), pcap_loop(), or pcap_next(), or pcap_next_ex() following a pcap_open_live(), + the SMP will pass down the monitor start command and various parameters the IOP should use. +
    IOP -> SMP + The IOP now sends a stream of captured data. +
    SMP + The SMP continuously reads the next packet from the reverse channel of the connection + between the SMP and the IOP that provides the captured data (via 'p->read_op' + which is 'pcap_read_linux()' until 'cnt' packets have been received. + The specified callback function will be invoked for each packet received. +
    IOP + The IOP continues to listen for additional commands as well as capturing and forwarding data to the SMP. +
    pcap_next() + It reads the next packet (by calling pcap_dispatch() with a count of 1) + and returns a pointer to the data in that packet. +
    + + + + + + + + + + + + +
    SMP -> IOP + On the first invocation of pcap_dispatch(), pcap_loop(), or pcap_next(), or pcap_next_ex() following a pcap_open_live(), + the SMP will pass down the monitor start command and various parameters the IOP should use. +
    IOP -> SMP + The IOP now sends a stream of captured data. +
    SMP + The SMP reads only the next packet from the reverse channel of the connection + between the SMP and the IOP that provides the captured data (via calling pcap_dispatch() + with a count of 1) and returns a pointer to that data by invoking an internal callback. +
    IOP + The IOP continues to listen for additional commands as well as capturing and forwarding data to the SMP. +
    pcap_next_ex()Reads the next packet and returns a success/failure indication.
    + + + + + + + + + + + + +
    SMP -> IOP + On the first invocation of pcap_dispatch(), pcap_loop(), or pcap_next(), or pcap_next_ex() following a pcap_open_live(), + the SMP will pass down the monitor start command and various parameters the IOP should use. +
    IOP -> SMP + The IOP now sends a stream of captured data. +
    SMP + The SMP reads only the next packet from the reverse channel of the connection + between the SMP and the IOP that provides the captured data (via calling pcap_dispatch() + with a count of 1) and returns seperate pointers to both the + packet header and packet data by invoking an internal callback. +
    IOP + The IOP continues to listen for additional commands as well as capturing and forwarding data to the SMP. +
    pcap_setfilter()Used to specify a filter program.
    + + + + + + +
    SMP -> IOP + The SMP sends a 'set filter' command followed by the BPF commands. +
    IOP -> SMP + The IOP returns a null terminated error string if it failed to accept the filter. + If no error occured, then a NULL terminated empty string is returned instead. + Errors are: +
      +
    • "Invalid BPF." +
    • "Insufficient resources for BPF." +
    +
    pcap_stats()Fills in a pcap_stat struct with packet statistics.
    + + + + + + + + + +
    SMP -> IOP + The SMP sends a message to the IOP requesting its statistics. +
    IOP -> SMP + The IOP returns the statistics. +
    SMP + The SMP fills in the structure provided with the information retrieved from the IOP. +
    pcap_close()Closes the file and deallocates resources.
    + + + + + + +
    SMP -> IOP + The SMP closes the file descriptor, and if the descriptor is that of + the comminucation session with an IOP, it too is terminated. +
    IOP + If the IOP detects that its communication session with an SMP + has closed, it will terminate any monitoring in progress, + release any resources and close its end of the session. + It will not maintain persistance of any information or prior mode of operation. +
    +

+ +

+

SMP/IOP Inter-Process Communication Protocol

+ +
    +

  • Communications between an SMP and an IOP consists of a TCP session + between an ephemeral port on the SMP and the well known port of 49152 + (which is the first available port in the 'dynamic and/or private port' + range) on an IOP. +

  • Following a TCP open operation the IOP receives a null terminated + 'interface ID' string to determine the type of operation that follows: +

  • Every command received by an IOP implies a 'stop trace/stop forwarding' operation must + occur before executing the received command. +

  • A session is closed when the SMP closes the TCP session with the IOP. + Obviously monitoring and forwarding is also stopped at that time. + + Note: All multi-octet entities are sent in network neutral order. +

    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

Interface ID Naming Convention

+
    + Each interface within an IOP will be referred to uniquely. Since an currently contains + 8 monitorable WAN ports and a monitorable Ethernet port, the naming convention is: +

    +

    + + + + + + + + + + + + +
    Interface # Type Name
    1 WAN wan0
    2 WAN wan1
    3 WAN wan2
    4 WAN wan3
    5 WAN wan4
    6 WAN wan5
    7 WAN wan6
    8 WAN wan7
    9 Ethernet eth0

Packet Trace Data Format

+
    + The format of the trace data that is sent to the SMP follows a portion of the libpcap file format + and is summarized here. This format specifies the generic requirements needed to + be able to decode packets, but does not cover ACN specifics such as custom MAC addressing + and WAN protocol support. +

    + + Although a libpcap file begins with a global header followed by zero or + more records for each captured packet, trace data sent to the SMP does NOT begin with a global header. + A trace sequence looks like this: +

    + + + + + + + + + + +
     [Packet Header]  [Packet Data]  [Packet Header]  [Packet Data]  [Packet Header]  [Packet Data] ...
    + +

    Packet Header

    +
      + Each captured packet starts with a header that contains the following values + (in network neutral order): + + + 
      + uint32 tv_sec;  /* timestamp seconds */
+ uint32 tv_usec; /* timestamp microseconds */
+ uint32 caplen;  /* number of octets in the following packet */
+ uint32 len;     /* original length of packet on the wire */
+
      +       + + + + + + + + + + + + + + + + + + +
      tv_secThe date and time when this packet was captured. + This value is in seconds since January 1, 1970 00:00:00 GMT; + this is also known as a UN*X time_t. You can use the ANSI C + time() function from time.h to get this value, + but you might use a more optimized way to get this timestamp value. + If this timestamp isn't based on GMT (UTC), use thiszone + from the global header for adjustments.
      tv_usecThe microseconds when this packet was captured, as an offset to ts_sec. + Beware: this value must never reach 1 second (1,000,000), + in this case ts_sec must be increased instead!
      caplenThe number of bytes actually provided in the capture record. + This value should never become larger than len or the + snaplen value specified during the capture.
      lenThe length of the packet "on the wire" when it was captured. + If caplen and len differ, the actually + saved packet size was limited by the value of snaplen specified + during one of the capture directives such as pcap_dispatch().
      +
    + +

    Packet Data

    +
      + The actual packet data will immediately follow the packet header as a sequence of caplen octets. + Depending on the DLT encoding number assigned to the interface, the packet data will contain an additional + custom header used to convey WAN port related information. +
    + +

    ACN Custom Packet Header

    +
      + PCAP, Wireshark and Tcpdump enhancements have been added to the ACN to support + monitoring of its ports, however each of these facilities were focused on capturing + and displaying traffic from LAN interfaces. The SITA extentions to these facilities + are used to also provide the ability to capture, filter, and display information from + an ACN's WAN ports. +

      + Although each packet follows the standard libpcap format, since there are + two types of interfaces that can be monitored, the format of the data + packet varies slightly. +

      +

        +
      • For Ethernet (like) devices, the packet format is unchanged from the standard Pcap format. +
      • For WAN devices, the packet contains a 5 byte header that preceeds the actual captured data + described by the following table: +
      +

This time is an +approximation of the arrival or transmission time. If it is supplied by +the operating system running on the host on which the capture is being +done, there are several reasons why it might not precisely represent the +arrival or transmission time: +.IP +if the time stamp is applied to the packet when the networking stack +receives the packet, the networking stack might not see the packet until +an interrupt is delivered for the packet or a timer event causes the +networking device driver to poll for packets, and the time stamp might +not be applied until the packet has had some processing done by other +code in the networking stack, so there might be a significant delay +between the time when the last bit of the packet is received by the +capture device and when the networking stack time-stamps the packet; +.IP +the timer used to generate the time stamps might have low resolution, +for example, it might be a timer updated once per host operating system +timer tick, with the host operating system timer ticking once every few +milliseconds; +.IP +a high-resolution timer might use a counter that runs at a rate +dependent on the processor clock speed, and that clock speed might be +adjusted upwards or downwards over time and the timer might not be able +to compensate for all those adjustments; +.IP +the host operating system's clock might be adjusted over time to match a +time standard to which the host is being synchronized, which might be +done by temporarily slowing down or speeding up the clock or by making a +single adjustment; +.IP +different CPU cores on a multi-core or multi-processor system might be +running at different speeds, or might not have time counters all +synchronized, so packets time-stamped by different cores might not have +consistent time stamps. +.LP +In addition, packets time-stamped by different cores might be +time-stamped in one order and added to the queue of packets for libpcap +to read in another order, so time stamps might not be monotonically +increasing. +.LP +Some capture devices on some platforms can provide time stamps for +packets; those time stamps are usually high-resolution time stamps, and +are usually applied to the packet when the first or last bit of the +packet arrives, and are thus more accurate than time stamps provided by +the host operating system. Those time stamps might not, however, be +synchronized with the host operating system's clock, so that, for +example, the time stamp of a packet might not correspond to the time +stamp of an event on the host triggered by the arrival of that packet. +.LP +Depending on the capture device and the software on the host, libpcap +might allow different types of time stamp to be used. The +.BR pcap_list_tstamp_types (3PCAP) +routine provides, for a packet capture handle created by +.BR pcap_create (3PCAP) +but not yet activated by +.BR pcap_activate (3PCAP), +a list of time stamp types supported by the capture device for that +handle. +The list might be empty, in which case no choice of time stamp type is +offered for that capture device. If the list is not empty, the +.BR pcap_set_tstamp_type (3PCAP) +routine can be used after a +.B pcap_create() +call and before a +.B pcap_activate() +call to specify the type of time stamp to be used on the device. +The time stamp types are listed here; the first value is the #define to +use in code, the second value is the value returned by +.B pcap_tstamp_type_val_to_name(3PCAP) +and accepted by +.BR pcap_tstamp_type_name_to_val(3PCAP) . +.RS 5 +.TP 5 +.BR PCAP_TSTAMP_HOST " - " host +Time stamp provided by the host on which the capture is being done. The +precision of this time stamp is unspecified; it might or might not be +synchronized with the host operating system's clock. +.TP 5 +.BR PCAP_TSTAMP_HOST_LOWPREC " - " host_lowprec +Time stamp provided by the host on which the capture is being done. +This is a low-precision time stamp, synchronized with the host operating +system's clock. +.TP 5 +.BR PCAP_TSTAMP_HOST_HIPREC " - " host_hiprec +Time stamp provided by the host on which the capture is being done. +This is a high-precision time stamp; it might or might not be +synchronized with the host operating system's clock. It might be more +expensive to fetch than +.BR PCAP_TSTAMP_HOST_LOWPREC . +.TP 5 +.BR PCAP_TSTAMP_ADAPTER " - " adapter +Time stamp provided by the network adapter on which the capture is being +done. This is a high-precision time stamp, synchronized with the host +operating system's clock. +.TP 5 +.BR PCAP_TSTAMP_ADAPTER_UNSYNCED " - " adapter_unsynced +Time stamp provided by the network adapter on which the capture is being +done. This is a high-precision time stamp; it is not synchronized with +the host operating system's clock. +.RE +.LP +By default, when performing a live capture or reading from a savefile, +time stamps are supplied as seconds since January 1, 1970, 00:00:00 UTC, +and microseconds since that seconds value, even if higher-resolution +time stamps are available from the capture device or in the savefile. +If, when reading a savefile, the time stamps in the file have a higher +resolution than one microsecond, the additional digits of resolution are +discarded. +.LP +The +.BR pcap_set_tstamp_precision (3PCAP) +routine can be used after a +.B pcap_create() +call and after a +.B pcap_activate() +call to specify the resolution of the time stamps to get for the device. +If the hardware or software cannot supply a higher-resolution time +stamp, the +.B pcap_set_tstamp_precision() +call will fail, and the time stamps supplied after the +.B pcap_activate() +call will have microsecond resolution. +.LP +When opening a savefile, the +.BR \%pcap_open_offline_with_tstamp_precision (3PCAP) +and +.BR \%pcap_fopen_offline_with_tstamp_precision (3PCAP) +routines can be used to specify the resolution of time stamps to be read +from the file; if the time stamps in the file have a lower resolution, +the fraction-of-a-second portion of the time stamps will be scaled to +the specified resolution. +.LP +The +.BR pcap_get_tstamp_precision (3PCAP) +routine returns the resolution of time stamps that will be supplied; +when capturing packets, this does not reflect the actual precision of +the time stamp supplied by the hardware or operating system and, when +reading a savefile, this does not indicate the actual precision of time +stamps in the file. +.SH SEE ALSO +pcap(3PCAP) Property changes on: vendor/libpcap/1.9.1/pcap-tstamp.manmisc.in ___________________________________________________________________ Added: svn:eol-style ## -0,0 +1 ## +native \ No newline at end of property Added: svn:keywords ## -0,0 +1 ## +FreeBSD=%H \ No newline at end of property Added: svn:mime-type ## -0,0 +1 ## +text/plain \ No newline at end of property Index: vendor/libpcap/1.9.1/pcap-usb-linux.c =================================================================== --- vendor/libpcap/1.9.1/pcap-usb-linux.c (nonexistent) +++ vendor/libpcap/1.9.1/pcap-usb-linux.c (revision 353142) @@ -0,0 +1,1363 @@ +/* + * Copyright (c) 2006 Paolo Abeni (Italy) + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * + * 1.

All packets +on the network, even those destined for other hosts, are accessible +through this mechanism. +It also supports saving captured packets to a ``savefile'', and reading +packets from a ``savefile''. +.SS Opening a capture handle for reading +To open a handle for a live capture, given the name of the network or +other interface on which the capture should be done, call +.BR pcap_create (), +set the appropriate options on the handle, and then activate it with +.BR pcap_activate (). +.PP +To obtain a list of devices that can be opened for a live capture, call +.BR pcap_findalldevs (); +to free the list returned by +.BR pcap_findalldevs (), +call +.BR pcap_freealldevs (). +.BR pcap_lookupdev () +will return the first device on that list that is not a ``loopback`` +network interface. +.PP +To open a handle for a ``savefile'' from which to read packets, given the +pathname of the ``savefile'', call +.BR pcap_open_offline (); +to set up a handle for a ``savefile'', given a +.B "FILE\ *" +referring to a file already opened for reading, call +.BR pcap_fopen_offline (). +.PP +In order to get a ``fake'' +.B pcap_t +for use in routines that require a +.B pcap_t +as an argument, such as routines to open a ``savefile'' for writing and +to compile a filter expression, call +.BR pcap_open_dead (). +.PP +.BR pcap_create (), +.BR pcap_open_offline (), +.BR pcap_fopen_offline (), +and +.BR pcap_open_dead () +return a pointer to a +.BR pcap_t , +which is the handle used for reading packets from the capture stream or +the ``savefile'', and for finding out information about the capture +stream or ``savefile''. +To close a handle, use +.BR pcap_close (). +.PP +The options that can be set on a capture handle include +.IP "snapshot length" +If, when capturing, you capture the entire contents of the packet, that +requires more CPU time to copy the packet to your application, more disk +and possibly network bandwidth to write the packet data to a file, and +more disk space to save the packet. If you don't need the entire +contents of the packet - for example, if you are only interested in the +TCP headers of packets - you can set the "snapshot length" for the +capture to an appropriate value. If the snapshot length is set to +.IR snaplen , +and +.I snaplen +is less +than the size of a packet that is captured, only the first +.I snaplen +bytes of that packet will be captured and provided as packet data. +.IP +A snapshot length of 65535 should be sufficient, on most if not all +networks, to capture all the data available from the packet. +.IP +The snapshot length is set with +.BR pcap_set_snaplen (). +.IP "promiscuous mode" +On broadcast LANs such as Ethernet, if the network isn't switched, or if +the adapter is connected to a "mirror port" on a switch to which all +packets passing through the switch are sent, a network adapter receives +all packets on the LAN, including unicast or multicast packets not sent +to a network address that the network adapter isn't configured to +recognize. +.IP +Normally, the adapter will discard those packets; however, many network +adapters support "promiscuous mode", which is a mode in which all +packets, even if they are not sent to an address that the adapter +recognizes, are provided to the host. This is useful for passively +capturing traffic between two or more other hosts for analysis. +.IP +Note that even if an application does not set promiscuous mode, the +adapter could well be in promiscuous mode for some other reason. +.IP +For now, this doesn't work on the "any" device; if an argument of "any" +or NULL is supplied, the setting of promiscuous mode is ignored. +.IP +Promiscuous mode is set with +.BR pcap_set_promisc (). +.IP "monitor mode" +On IEEE 802.11 wireless LANs, even if an adapter is in promiscuous mode, +it will supply to the host only frames for the network with which it's +associated. It might also supply only data frames, not management or +control frames, and might not provide the 802.11 header or radio +information pseudo-header for those frames. +.IP +In "monitor mode", sometimes also called "rfmon mode" (for "Radio +Frequency MONitor"), the adapter will supply all frames that it +receives, with 802.11 headers, and might supply a pseudo-header with +radio information about the frame as well. +.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 +Monitor mode is set with +.BR pcap_set_rfmon (), +and +.BR pcap_can_set_rfmon () +can be used to determine whether an adapter can be put into monitor +mode. +.IP "packet buffer timeout" +If, when capturing, packets are delivered as soon as they arrive, the +application capturing the packets will be woken up for each packet as it +arrives, and might have to make one or more calls to the operating +system to fetch each packet. +.IP +If, instead, packets are not delivered as soon as they arrive, but are +delivered after a short delay (called a "packet buffer timeout"), more +than one packet can be accumulated before the packets are delivered, so +that a single wakeup would be done for multiple packets, and each set of +calls made to the operating system would supply multiple packets, rather +than a single packet. This reduces the per-packet CPU overhead if +packets are arriving at a high rate, increasing the number of packets +per second that can be captured. +.IP +The packet buffer timeout is required so that an application won't wait +for the operating system's capture buffer to fill up before packets are +delivered; if packets are arriving slowly, that wait could take an +arbitrarily long period of time. +.IP +Not all platforms support a packet buffer timeout; on platforms that +don't, the packet buffer timeout is ignored. A zero value for the +timeout, on platforms that support a packet buffer timeout, will cause a +read to wait forever to allow enough packets to arrive, with no timeout. +A negative value is invalid; the result of setting the timeout to a +negative value is unpredictable. +.IP +.BR NOTE : +the packet buffer timeout cannot be used to cause calls that read +packets to return within a limited period of time, because, on some +platforms, the packet buffer timeout isn't supported, and, on other +platforms, the timer doesn't start until at least one packet arrives. +This means that the packet buffer timeout should +.B NOT +be used, for example, in an interactive application to allow the packet +capture loop to ``poll'' for user input periodically, as there's no +guarantee that a call reading packets will return after the timeout +expires even if no packets have arrived. +.IP +The packet buffer timeout is set with +.BR pcap_set_timeout (). +.IP "immediate mode" +In immediate mode, packets are always delivered as soon as they arrive, +with no buffering. Immediate mode is set with +.BR pcap_set_immediate_mode (). +.IP "buffer size" +Packets that arrive for a capture are stored in a buffer, so that they +do not have to be read by the application as soon as they arrive. On +some platforms, the buffer's size can be set; a size that's too small +could mean that, if too many packets are being captured and the snapshot +length doesn't limit the amount of data that's buffered, packets could +be dropped if the buffer fills up before the application can read +packets from it, while a size that's too large could use more +non-pageable operating system memory than is necessary to prevent +packets from being dropped. +.IP +The buffer size is set with +.BR pcap_set_buffer_size (). +.IP "timestamp type" +On some platforms, the time stamp given to packets on live captures can +come from different sources that can have different resolutions or that +can have different relationships to the time values for the current time +supplied by routines on the native operating system. See +.BR pcap-tstamp (@MAN_MISC_INFO@) +for a list of time stamp types. +.IP +The time stamp type is set with +.BR pcap_set_tstamp_type (). +.PP +Reading packets from a network interface may require that you have +special privileges: +.TP +.B Under SunOS 3.x or 4.x with NIT or BPF: +You must have read access to +.I /dev/nit +or +.IR /dev/bpf* . +.TP +.B Under Solaris with DLPI: +You must have read/write access to the network pseudo device, e.g. +.IR /dev/le . +On at least some versions of Solaris, however, this is not sufficient to +allow +.I tcpdump +to capture in promiscuous mode; on those versions of Solaris, you must +be root, or the application capturing packets +must be installed setuid to root, in order to capture in promiscuous +mode. Note that, on many (perhaps all) interfaces, if you don't capture +in promiscuous mode, you will not see any outgoing packets, so a capture +not done in promiscuous mode may not be very useful. +.IP +In newer versions of Solaris, you must have been given the +.B net_rawaccess +privilege; this is both necessary and sufficient to give you access to the +network pseudo-device - there is no need to change the privileges on +that device. A user can be given that privilege by, for example, adding +that privilege to the user's +.B defaultpriv +key with the +.B usermod (@MAN_ADMIN_COMMANDS@) +command. +.TP +.B Under HP-UX with DLPI: +You must be root or the application capturing packets must be installed +setuid to root. +.TP +.B Under IRIX with snoop: +You must be root or the application capturing packets must be installed +setuid to root. +.TP +.B Under Linux: +You must be root or the application capturing packets must be installed +setuid to root (unless your distribution has a kernel +that supports capability bits such as CAP_NET_RAW and code to allow +those capability bits to be given to particular accounts and to cause +those bits to be set on a user's initial processes when they log in, in +which case you must have CAP_NET_RAW in order to capture and +CAP_NET_ADMIN to enumerate network devices with, for example, the +.B \-D +flag). +.TP +.B Under ULTRIX and Digital UNIX/Tru64 UNIX: +Any user may capture network traffic. +However, no user (not even the super-user) can capture in promiscuous +mode on an interface unless the super-user has enabled promiscuous-mode +operation on that interface using +.IR pfconfig (8), +and no user (not even the super-user) can capture unicast traffic +received by or sent by the machine on an interface unless the super-user +has enabled copy-all-mode operation on that interface using +.IR pfconfig , +so +.I useful +packet capture on an interface probably requires that either +promiscuous-mode or copy-all-mode operation, or both modes of +operation, be enabled on that interface. +.TP +.B Under BSD (this includes macOS): +You must have read access to +.I /dev/bpf* +on systems that don't have a cloning BPF device, or to +.I /dev/bpf +on systems that do. +On BSDs with a devfs (this includes macOS), this might involve more +than just having somebody with super-user access setting the ownership +or permissions on the BPF devices - it might involve configuring devfs +to set the ownership or permissions every time the system is booted, +if the system even supports that; if it doesn't support that, you might +have to find some other way to make that happen at boot time. +.PP +Reading a saved packet file doesn't require special privileges. +.PP +The packets read from the handle may include a ``pseudo-header'' +containing various forms of packet meta-data, and probably includes a +link-layer header whose contents can differ for different network +interfaces. To determine the format of the packets supplied by the +handle, call +.BR pcap_datalink (); +.I https://www.tcpdump.org/linktypes.html +lists the values it returns and describes the packet formats that +correspond to those values. +.PP +Do +.B NOT +assume that the packets for a given capture or ``savefile`` will have +any given link-layer header type, such as +.B DLT_EN10MB +for Ethernet. For example, the "any" device on Linux will have a +link-layer header type of +.B DLT_LINUX_SLL +even if all devices on the system at the time the "any" device is opened +have some other data link type, such as +.B DLT_EN10MB +for Ethernet. +.PP +To obtain the +.B "FILE\ *" +corresponding to a +.B pcap_t +opened for a ``savefile'', call +.BR pcap_file (). +.TP +.B Routines +.RS +.TP +.BR pcap_create (3PCAP) +get a +.B pcap_t +for live capture +.TP +.BR pcap_activate (3PCAP) +activate a +.B pcap_t +for live capture +.TP +.BR pcap_findalldevs (3PCAP) +get a list of devices that can be opened for a live capture +.TP +.BR pcap_freealldevs (3PCAP) +free list of devices +.TP +.BR pcap_lookupdev (3PCAP) +get first non-loopback device on that list +.TP +.BR pcap_open_offline (3PCAP) +open a +.B pcap_t +for a ``savefile'', given a pathname +.TP +.BR pcap_open_offline_with_tstamp_precision (3PCAP) +open a +.B pcap_t +for a ``savefile'', given a pathname, and specify the precision to +provide for packet time stamps +.TP +.BR pcap_fopen_offline (3PCAP) +open a +.B pcap_t +for a ``savefile'', given a +.B "FILE\ *" +.TP +.BR pcap_fopen_offline_with_tstamp_precision (3PCAP) +open a +.B pcap_t +for a ``savefile'', given a +.BR "FILE\ *" , +and specify the precision to provide for packet time stamps +.TP +.BR pcap_open_dead (3PCAP) +create a ``fake'' +.B pcap_t +.TP +.BR pcap_close (3PCAP) +close a +.B pcap_t +.TP +.BR pcap_set_snaplen (3PCAP) +set the snapshot length for a not-yet-activated +.B pcap_t +for live capture +.TP +.BR pcap_snapshot (3PCAP) +get the snapshot length for a +.B pcap_t +.TP +.BR pcap_set_promisc (3PCAP) +set promiscuous mode for a not-yet-activated +.B pcap_t +for live capture +.TP +.BR pcap_set_protocol_linux (3PCAP) +set capture protocol for a not-yet-activated +.B pcap_t +for live capture (Linux only) +.TP +.BR pcap_set_rfmon (3PCAP) +set monitor mode for a not-yet-activated +.B pcap_t +for live capture +.TP +.BR pcap_can_set_rfmon (3PCAP) +determine whether monitor mode can be set for a +.B pcap_t +for live capture +.TP +.BR pcap_set_timeout (3PCAP) +set packet buffer timeout for a not-yet-activated +.B pcap_t +for live capture +.TP +.BR pcap_set_immediate_mode (3PCAP) +set immediate mode for a not-yet-activated +.B pcap_t +for live capture +.TP +.BR pcap_set_buffer_size (3PCAP) +set buffer size for a not-yet-activated +.B pcap_t +for live capture +.TP +.BR pcap_set_tstamp_type (3PCAP) +set time stamp type for a not-yet-activated +.B pcap_t +for live capture +.TP +.BR pcap_list_tstamp_types (3PCAP) +get list of available time stamp types for a not-yet-activated +.B pcap_t +for live capture +.TP +.BR pcap_free_tstamp_types (3PCAP) +free list of available time stamp types +.TP +.BR pcap_tstamp_type_val_to_name (3PCAP) +get name for a time stamp type +.TP +.BR pcap_tstamp_type_val_to_description (3PCAP) +get description for a time stamp type +.TP +.BR pcap_tstamp_type_name_to_val (3PCAP) +get time stamp type corresponding to a name +.TP +.BR pcap_set_tstamp_precision (3PCAP) +set time stamp precision for a not-yet-activated +.B pcap_t +for live capture +.TP +.BR pcap_get_tstamp_precision (3PCAP) +get the time stamp precision of a +.B pcap_t +for live capture +.TP +.BR pcap_datalink (3PCAP) +get link-layer header type for a +.B pcap_t +.TP +.BR pcap_file (3PCAP) +get the +.B "FILE\ *" +for a +.B pcap_t +opened for a ``savefile'' +.TP +.BR pcap_is_swapped (3PCAP) +determine whether a ``savefile'' being read came from a machine with the +opposite byte order +.TP +.BR pcap_major_version (3PCAP) +.PD 0 +.TP +.BR pcap_minor_version (3PCAP) +get the major and minor version of the file format version for a +``savefile'' +.PD +.RE +.SS Selecting a link-layer header type for a live capture +Some devices may provide more than one link-layer header type. To +obtain a list of all link-layer header types provided by a device, call +.BR pcap_list_datalinks () +on an activated +.B pcap_t +for the device. +To free a list of link-layer header types, call +.BR pcap_free_datalinks (). +To set the link-layer header type for a device, call +.BR pcap_set_datalink (). +This should be done after the device has been activated but before any +packets are read and before any filters are compiled or installed. +.TP +.B Routines +.RS +.TP +.BR pcap_list_datalinks (3PCAP) +get a list of link-layer header types for a device +.TP +.BR pcap_free_datalinks (3PCAP) +free list of link-layer header types +.TP +.BR pcap_set_datalink (3PCAP) +set link-layer header type for a device +.TP +.BR pcap_datalink_val_to_name (3PCAP) +get name for a link-layer header type +.TP +.BR pcap_datalink_val_to_description (3PCAP) +get description for a link-layer header type +.TP +.BR pcap_datalink_name_to_val (3PCAP) +get link-layer header type corresponding to a name +.RE +.SS Reading packets +Packets are read with +.BR pcap_dispatch () +or +.BR pcap_loop (), +which process one or more packets, calling a callback routine for each +packet, or with +.BR pcap_next () +or +.BR pcap_next_ex (), +which return the next packet. +The callback for +.BR pcap_dispatch () +and +.BR pcap_loop () +is supplied a pointer to a +.IR "struct pcap_pkthdr" , +which includes the following members: +.RS +.TP +.B ts +a +.I struct timeval +containing the time when the packet was captured +.TP +.B caplen +a +.I bpf_u_int32 +giving the number of bytes of the packet that are available from the +capture +.TP +.B len +a +.I bpf_u_int32 +giving the length of the packet, in bytes (which might be more than the +number of bytes available from the capture, if the length of the packet +is larger than the maximum number of bytes to capture). +.RE +.PP +The callback is also supplied a +.I const u_char +pointer to the first +.B caplen +(as given in the +.I struct pcap_pkthdr +mentioned above) +bytes of data from the packet. This won't necessarily be the entire +packet; to capture the entire packet, you will have to provide a value +for +.I snaplen +in your call to +.BR pcap_set_snaplen () +that is sufficiently large to get all of the packet's data - a value of +65535 should be sufficient on most if not all networks). When reading +from a ``savefile'', the snapshot length specified when the capture was +performed will limit the amount of packet data available. +.PP +.BR pcap_next () +is passed an argument that points to a +.I struct pcap_pkthdr +structure, and fills it in with the time stamp and length values for the +packet. It returns a +.I const u_char +to the first +.B caplen +bytes of the packet on success, and NULL on error. +.PP +.BR pcap_next_ex () +is passed two pointer arguments, one of which points to a +.IR struct pcap_pkthdr * +and one of which points to a +.IR "const u_char" *. +It sets the first pointer to point to a +.I struct pcap_pkthdr +structure with the time stamp and length values for the packet, and sets +the second pointer to point to the first +.B caplen +bytes of the packet. +.PP +To force the loop in +.BR pcap_dispatch () +or +.BR pcap_loop () +to terminate, call +.BR pcap_breakloop (). +.PP +By default, when reading packets from an interface opened for a live +capture, +.BR pcap_dispatch (), +.BR pcap_next (), +and +.BR pcap_next_ex () +will, if no packets are currently available to be read, block waiting +for packets to become available. On some, but +.I not +all, platforms, if a packet buffer timeout was specified, the wait will +terminate after the packet buffer timeout expires; applications should +be prepared for this, as it happens on some platforms, but should not +rely on it, as it does not happen on other platforms. Note that the +wait might, or might not, terminate even if no packets are available; +applications should be prepared for this to happen, but must not rely on +it happening. +.PP +A handle can be put into ``non-blocking mode'', so that those routines +will, rather than blocking, return an indication that no packets are +available to read. Call +.BR pcap_setnonblock () +to put a handle into non-blocking mode or to take it out of non-blocking +mode; call +.BR pcap_getnonblock () +to determine whether a handle is in non-blocking mode. Note that +non-blocking mode does not work correctly in Mac OS X 10.6. +.PP +Non-blocking mode is often combined with routines such as +.BR select (2) +or +.BR poll (2) +or other routines a platform offers to wait for any of a set of +descriptors to be ready to read. To obtain, for a handle, a descriptor +that can be used in those routines, call +.BR pcap_get_selectable_fd (). +If the routine indicates that data is +available to read on the descriptor, an attempt should be made to read +from the device. +.PP +Not all handles have such a descriptor available; +.BR pcap_get_selectable_fd () +will return +.B PCAP_ERROR +if no such descriptor is available. If no such +descriptor is available, this may be because the device must be polled +periodically for packets; in that case, +.BR pcap_get_required_select_timeout () +will return a pointer to a +.B struct timeval +whose value can be used as a timeout in those routines. When the +routine returns, an attmept should be made to read packets from the +device. If +.BR pcap_get_required_select_timeout () +returns NULL, no such timeout is available, and those routines cannot be +used with the device. +.PP +In addition, for various +reasons, one or more of those routines will not work properly with the +descriptor; the documentation for +.BR pcap_get_selectable_fd () +gives details. Note that, just as an attempt to read packets from a +.B pcap_t +may not return any packets if the packet buffer timeout expires, a +.BR select (), +.BR poll (), +or other such call may, if the packet buffer timeout expires, indicate +that a descriptor is ready to read even if there are no packets +available to read. +.TP +.B Routines +.RS +.TP +.BR pcap_dispatch (3PCAP) +read a bufferful of packets from a +.B pcap_t +open for a live capture or the full set of packets from a +.B pcap_t +open for a ``savefile'' +.TP +.BR pcap_loop (3PCAP) +read packets from a +.B pcap_t +until an interrupt or error occurs +.TP +.BR pcap_next (3PCAP) +read the next packet from a +.B pcap_t +without an indication whether an error occurred +.TP +.BR pcap_next_ex (3PCAP) +read the next packet from a +.B pcap_t +with an error indication on an error +.TP +.BR pcap_breakloop (3PCAP) +prematurely terminate the loop in +.BR pcap_dispatch () +or +.BR pcap_loop () +.TP +.BR pcap_setnonblock (3PCAP) +set or clear non-blocking mode on a +.B pcap_t +.TP +.BR pcap_getnonblock (3PCAP) +get the state of non-blocking mode for a +.B pcap_t +.TP +.BR pcap_get_selectable_fd (3PCAP) +attempt to get a descriptor for a +.B pcap_t +that can be used in calls such as +.BR select (2) +and +.BR poll (2) +.TP +.BR pcap_get_required_select_timeout (3PCAP) +if no descriptor usable with +.BR select (2) +and +.BR poll (2) +is available for the +.BR pcap_t , +attempt to get a timeout usable with those routines +.RE +.SS Filters +In order to cause only certain packets to be returned when reading +packets, a filter can be set on a handle.

The client then sends the appropriate commands +to rpcapd to start the capture. +.LP +Active mode is useful in case +.B rpcapd +is run behind a firewall and +cannot receive connections from the external world. In this case, +.B rpcapd +can be configured to establish the connection to a given host, +which has to be configured in order to wait for that connection. After +establishing the connection, the protocol continues its job in almost +the same way in both active and passive mode. +.SH Configuration file +.LP +The user can create a configuration file in the same folder of the +executable, and put the configuration commands in there. In order for +rpcapd to execute the commands, you have to restart it on Win32, i.e. +the initialization file is parsed only at the beginning). The UNIX +version of rpcapd will reread the configuration file when receiving a +HUP signel. In that case, all the existing connections remain in place, +while the new connections will be created according to the new parameters. +.LP +In case a user does not want to create the configuration file manually, +they can launch rpcapd with the requested parameters plus "-s filename". +Rpcapd will parse all the parameters and save them into the specified +configuration file. +.SH Installing rpcapd on Win32 +.LP +The remote daemon is installed automatically when installing WinPcap. +The installation process places the rpcapd file into the WinPcap folder. +This file can be executed either from the command line, or as a service. +For instance, the installation process updates the list of available +services list and it creates a new item (Remote Packet Capture Protocol +v.0 (experimental) ). To avoid security problems, the service is +inactive and it has to be started manually (control panel - +administrative tools - services - start). +.LP +The service has a set of "standard" parameters, i.e. it is launched +with the +.B \-d +flag (in order to make it run as a service) and the +.B "-f rpcapd.ini" +flag. +.SH Starting rpcapd on Win32 +.LP +The rpcapd executable can be launched directly, i.e. it can run in the +foreground as well (not as a daemon/service).
