497 Michael C. Richardson <mcr@sandelman.ottawa.on.ca>
498 - Created tcpdump.org repository
500 v3.4 Sat Jul 25 12:40:55 PDT 1998
502 - Hardwire Linux slip support since it's too hard to detect.
504 - Redo configuration of "network" libraries (-lsocket and -lnsl) to
505 deal with IRIX. Thanks to John Hawkinson (jhawk@mit.edu)
507 - Added -a which tries to translate network and broadcast addresses to
508 names. Suggested by Rob van Nieuwkerk (robn@verdi.et.tudelft.nl)
510 - Added a configure option to disable gcc.
512 - Added a "raw" packet printer.
514 - Not having an interface address is no longer fatal. Requested by John
515 Hawkinson.

533 (paul@vix.com)
535 - Fix off-by-one bug when testing size of ethernet packets. Thanks to
536 Marty Leisner (leisner@sdsp.mc.xerox.com)
538 - Add a local autoconf macro to check for routines in libraries; the
539 autoconf version is broken (it only puts the library name in the
540 cache variable name). Thanks to John Hawkinson.
542 - Add a local autoconf macro to check for types; the autoconf version
543 is broken (it uses grep instead of actually compiling a code fragment).
545 - Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
546 formats.
548 - Extend OSF ip header workaround to versions 1 and 2.
550 - Fix some signed problems in the nfs printer. As reported by David
551 Sacerdote (davids@silence.secnet.com)
553 - Detect group wheel and use it as the default since BSD/OS' install
554 can't hack numeric groups. Reported by David Sacerdote.
556 - AIX needs special loader options. Thanks to Jonathan I. Kamens
557 (jik@cam.ov.com)
559 - Fixed the nfs printer to print port numbers in decimal. Thanks to

582 - Add missing m4 quoting in AC_LBL_UNALIGNED_ACCESS autoconf macro.
583 Reported by Joachim Ott (ott@ardala.han.de)
585 - Enable "ip_hl vs. ip_vhl" workaround for OSF4 too.
587 - Print arp hardware type in host order. Thanks to Onno van der Linden
588 (onno@simplex.nl)
590 - Avoid solaris compiler warnings. Thanks to Bruce Barnett
591 (barnett@grymoire.crd.ge.com)
593 - Fix rip printer to not print one more route than is actually in the
594 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
595 Bill Fenner (fenner@parc.xerox.com)
597 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
599 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
600 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
602 - Rewrite ospf printer to improve truncation checks.
604 - Don't parse tcp options past the EOL. As noted by David Sacerdote
605 (davids@secnet.com). Also, check tcp options to make sure they ar
606 actually in the tcp header (in addition to the normal truncation
607 checks). Fix the SACK code to print the N blocks (instead of the
608 first block N times).
610 - Don't say really small UDP packets are truncated just because they
611 aren't big enough to be a RPC. As noted by David Sacerdote.
613 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
615 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
616 (martin@msp.se)
618 - Print mtu for icmp unreach need frag packets. Thanks to John
619 Hawkinson (jhawk@mit.edu)
621 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
622 (jch@bsdi.com)
624 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
625 (kushida@trl.ibm.co.jp)
627 - Check igmp checksum if possible. Thanks to John Hawkinson.
629 - Made changes for SINIX. Thanks to Andrej Borsenkow
630 (borsenkow.msk@sni.de)
632 - Use autoconf's idea of the top level directory in install targets.
633 Thanks to John Hawkinson.
635 - Avoid infinite loop in tcp options printing code. Thanks to Jeffrey
636 Mogul (mogul@pa.dec.com)
638 - Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
639 Thanks to John Hawkinson.
641 - Added some more packet truncation checks.
643 - On systems that have it, use sigset() instead of signal() since
644 signal() has different semantics on these systems.
646 - Fixed some more alignment problems on the alpha.
648 - Add code to massage unprintable characters in the domain and ipx
649 printers. Thanks to John Hawkinson.
651 - Added explicit netmask support. Thanks to Steve Nuchia
652 (steve@research.oknet.com)
654 - Add "sca" keyword (for DEC cluster services) as suggested by Terry
655 Kennedy (terry@spcvxa.spc.edu)

659 - Added an igrp printer. Thanks to Francis Dupont
660 (francis.dupont@inria.fr)
662 - Print IPX net numbers in hex a la Novell Netware. Thanks to Terry
663 Kennedy (terry@spcvxa.spc.edu)
665 - Fixed snmp extended tag field parsing bug. Thanks to Pascal Hennequin
666 (pascal.hennequin@hugo.int-evry.fr)
668 - Added some ETHERTYPEs missing on some systems.
670 - Added truncated packet macros and various checks.
672 - Fixed endian problems with the DECnet printer.
674 - Use $CC when checking gcc version. Thanks to Carl Lindberg
675 (carl_lindberg@blacksmith.com)

678 John Hawkinson.
680 - Fix bugs in the autoconf misaligned accesses code fragment.
682 - Include sys/param.h to get BYTE_ORDER in a few places. Thanks to
683 Pavlin Ivanov Radoslavov (pavlin@cs.titech.ac.jp)
685 v3.2 Sun Jun 23 02:28:10 PDT 1996
687 - Print new icmp unreachable codes as suggested by Martin Fredriksson
688 (martin@msp.se). Also print code value when unknown for icmp redirect
689 and time exceeded.
691 - Fix an alignment endian bug in getname(). Thanks to John Hawkinson.
693 - Define "new" domain record types if not found in arpa/nameserv.h.

695 fixed an endian bug when printing mx record and added some new record
696 types.
698 - Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
700 - Added T/TCP options printing. As suggested by Richard Stevens
701 (rstevens@noao.edu)

704 accesses.
706 v3.1 Thu Jun 13 20:59:32 PDT 1996
708 - Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
709 and bind (as suggested by Charles Hannum).
711 - Port to GNU autoconf.
713 - Add support for printing DVMRP and PIM traffic thanks to
714 Havard Eidnes (Havard.Eidnes@runit.sintef.no).
716 - Fix AppleTalk, IPX and DECnet byte order problems due to wrong endian
717 define being referenced. Reported by Terry Kennedy.
719 - Minor fixes to the man page thanks to Mark Andrews.
721 - Endian fixes to RTP and vat packet dumpers, thanks to Bruce Mah

733 - Check return status from pcap_loop() so we can print an error and
734 exit with a bad status if there were problems.
736 - Bail if ip option length is <= 0. Resulted from a bug report from
737 Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).

746 - Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
747 (crawdad@fnal.gov).
749 - Fix ntp_print() to not print garbage when the stratum is

753 selective acknowledgment case.
755 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
756 (jch@bsdi.com)

759 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
760 (toku@dit.co.jp)
762 - Don't checksum ip header if we don't have all of it. Thanks to John
763 Hawkinson (jhawk@mit.edu).
765 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
766 Honig (jhc@bsdi.com)
769 v3.1a1 Wed May 3 19:21:11 PDT 1995
771 - Include time.h when SVR4 is defined to avoid problems under Solaris
772 2.3.
774 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
775 strings, not the local buffer. Thanks to Stefan Petri
776 (petri@ibr.cs.tu-bs.de).
778 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
779 that the selected value was not used. Thanks to Pascal Hennequin
780 (Pascal.Hennequin@hugo.int-evry.fr).
782 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
784 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
786 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
788 - Although there never was a 3.0.3 release, the linux boys cleverly
789 "released" one in late 1995.
791 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
793 - Change configuration to not use gcc v2 flags with gcc v1.
795 - Redo gmt2local() so that it works under BSDI (which seems to return
796 an empty timezone struct from gettimeofday()). Based on report from
797 Terry Kennedy (terry@spcvxa.spc.edu).
799 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
800 on report from Mark Andrews (mandrews@alias.com).
802 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
803 Orth (ro@techfak.uni-bielefeld.de).
805 - Fixed printout of connection id for uncompressed tcp slip packets.
806 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
808 - Hack around deficiency in Ultrix's make.
810 - Add ETHERTYPE_TRAIL define which is missing from irix5.
812 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
814 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
816 v3.0 Mon Jun 20 19:23:27 PDT 1994
818 - Added support for printing tcp option timestamps thanks to
819 Mark Andrews (mandrews@alias.com).
821 - Reorganize protocol dumpers to take const pointers to packets so they
822 never change the contents (i.e., they used to do endian conversions
823 in place). Previously, whenever more than one pass was taken over
824 the packet, the packet contents would be dumped incorrectly (i.e.,
825 the output form -x would be wrong on little endian machines because
826 the protocol dumpers would modify the data). Thanks to Charles Hannum
827 (mycroft@gnu.ai.mit.edu) for reporting this problem.
829 - Added support for decnet protocol dumping thanks to Jeff Mogul
830 (mogul@pa.dec.com).
832 - Fix bug that caused length of packet to be incorrectly printed
833 (off by ether header size) for unknown ethernet types thanks
834 to Greg Miller (gmiller@kayak.mitre.org).
836 - Added support for IPX protocol dumping thanks to Brad Parker
837 (brad@fcr.com).
839 - Added check to verify IP header checksum under -v thanks to
840 Brad Parker (brad@fcr.com).
842 - Move packet capture code to new libpcap library (which is
843 packaged separately).
845 - Prototype everything and assume an ansi compiler.
847 - print-arp.c: Print hardware ethernet addresses if they're not
848 what we expect.
850 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
851 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
853 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
854 (mogul@pa.dec.com).
856 - print-icmp.c: Byte swap netmask before printing. Thanks to
857 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
859 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
860 By default, only the inner packet is dumped, appended with the token
861 "(encap)". Under -v, both the inner and output packets are dumped
862 (on the same line). Note that the filter applies to the original packet,
863 not the encapsulated packet. So if you run tcpdump on a net with an
864 IP Multicast tunnel, you cannot filter out the datagrams using the
865 conventional syntax. (You can filter away all the ip-in-ip traffic
866 with "not ip proto 4".)
868 - print-nfs.c: Keep pending rpc's in circular table. Add generic
869 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
871 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
873 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
874 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
875 Add && and || operators
877 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
879 - Fix bug with -c flag.
881 v2.2 Fri May 22 17:19:41 PDT 1992
883 - savefile.c: Remove hack that shouldn't have been exported. Add
884 truncate checks.
886 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
887 matches non-echo/reply ICMP packets.
889 - Many improvements to filter code optimizer.
891 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
892 so that protocol qualifications are allowed. For example, "ip broadcast"
893 and "ether multicast" are valid filters.
895 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
896 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
897 patches to netinet/if_loop.c.
899 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
900 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
902 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
904 v2.1 Tue Jan 28 11:00:14 PST 1992
906 - Internal release (never publically exported).
908 v2.0.1 Sun Jan 26 21:10:10 PDT
910 - Various byte ordering fixes.
912 - Add truncation checks.
914 - inet.c: Support BSD style SIOCGIFCONF.
916 - nametoaddr.c: Handle multi addresses for single host.
918 - optimize.c: Rewritten.
920 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
921 for broadcast nets.
923 - print-atal.c: Fix an alignment bug (thanks to
924 stanonik@nprdc.navy.mil) Add missing printf() argument.
926 - print-bootp.c: First attempt at decoding the vendor buffer.
928 - print-domain.c: Fix truncation checks.
930 - print-icmp.c: Calculate length of packets from the ip header.
932 - print-ip.c: Print frag id in decimal (so it's easier to match up
933 with non-frags). Add support for ospf, egp and igmp.
935 - print-nfs.c: Lots of changes.
937 - print-ntp.c: Make some verbose output depend on -v.
939 - print-snmp.c: New version from John LoVerso.
941 - print-tcp.c: Print rfc1072 tcp options.
943 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
944 (microseconds) worth of precision. Fix uid bugs.
946 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
947 With this option, you can create an architecture independent binary
948 trace file in real time, without the overhead of the packet printer.
949 At a later time, the packets can be filtered (again) and printed.
951 - BSD is supported. You must have BPF in your kernel.
952 Since the filtering is now done in the kernel, fewer packets are
953 dropped. In fact, with BPF and the packet dumper option, a measly
954 Sun 3/50 can keep up with a busy network.
956 - Compressed SLIP packets can now be dumped, provided you use our
957 SLIP software and BPF. These packets are dumped as any other IP
958 packet; the compressed headers are dumped with the '-e' option.
960 - Machines with little-endian byte ordering are supported (thanks to
961 Jeff Mogul).
963 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
965 - IBM RT and Stanford Enetfilter support has been added by
966 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
967 both the vanilla Enetfilter interface, and the extended interface
968 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
970 - TFTP packets are now printed (requests only).
972 - BOOTP packets are now printed.
974 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
976 - Sparc architectures, including the Sparcstation-1, are now
977 supported thanks to Steve McCanne and Craig Leres.
979 - SunOS 4 is now supported thanks to Micky Liu of Columbia
980 University (micky@cunixc.cc.columbia.edu).
982 - IP options are now printed.
984 - RIP packets are now printed.
986 - There's a -v flag that prints out more information than the
987 default (e.g., it will enable printing of IP ttl, tos and id)
988 and -q flag that prints out less (e.g., it will disable
989 interpretation of AppleTalk-in-UDP).
991 - The grammar has undergone substantial changes (if you have an
992 earlier version of tcpdump, you should re-read the manual
993 entry).
995 The most useful change is the addition of an expression
996 syntax that lets you filter on arbitrary fields or values in the
997 packet. E.g., "ip[0] > 0x45" would print only packets with IP
998 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
999 packets.
1001 The most painful change is that concatenation no longer means
1002 "and" -- e.g., you have to say "host foo and port bar" instead
1003 of "host foo port bar". The up side to this down is that
1004 repeated qualifiers can be omitted, making most filter
1005 expressions shorter. E.g., you can now say "ip host foo and
1006 (bar or baz)" to look at ip traffic between hosts foo and bar or
1007 between hosts foo and baz. [The old way of saying this was "ip
1008 host foo and (ip host bar or ip host baz)".]
1010 v2.0 Sun Jan 13 12:20:40 PST 1991
1012 - Initial public release.
