537 - Created tcpdump.org repository
539 v3.4 Sat Jul 25 12:40:55 PDT 1998
541 - Hardwire Linux slip support since it's too hard to detect.
543 - Redo configuration of "network" libraries (-lsocket and -lnsl) to
544 deal with IRIX. Thanks to John Hawkinson (jhawk@mit.edu)

559 using MD5 authentication. Thanks to Brian Wellington
562 - Fix truncation check bugs in the Kerberos printer. Reported by Ezra
563 Peisach (epeisach@mit.edu)
565 - Don't catch SIGHUP when invoked with nohup(1). Thanks to Dave Plonka

575 Marty Leisner (leisner@sdsp.mc.xerox.com)
577 - Add a local autoconf macro to check for routines in libraries; the
578 autoconf version is broken (it only puts the library name in the
579 cache variable name). Thanks to John Hawkinson.
581 - Add a local autoconf macro to check for types; the autoconf version
582 is broken (it uses grep instead of actually compiling a code fragment).
584 - Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
587 - Extend OSF ip header workaround to versions 1 and 2.
589 - Fix some signed problems in the nfs printer. As reported by David
590 Sacerdote (davids@silence.secnet.com)
592 - Detect group wheel and use it as the default since BSD/OS' install
593 can't hack numeric groups. Reported by David Sacerdote.
595 - AIX needs special loader options. Thanks to Jonathan I. Kamens
598 - Fixed the nfs printer to print port numbers in decimal. Thanks to

605 - Attempt to detect "egcs" versions of gcc.
607 - Add missing closing double quotes when displaying bootp strings.
608 Reported by Viet-Trung Luu (vluu@picard.math.uwaterloo.ca)

629 - Avoid solaris compiler warnings. Thanks to Bruce Barnett
630 (barnett@grymoire.crd.ge.com)
632 - Fix rip printer to not print one more route than is actually in the
633 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
634 Bill Fenner (fenner@parc.xerox.com)
636 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
638 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
639 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
641 - Rewrite ospf printer to improve truncation checks.
643 - Don't parse tcp options past the EOL. As noted by David Sacerdote
644 (davids@secnet.com). Also, check tcp options to make sure they ar
645 actually in the tcp header (in addition to the normal truncation
646 checks). Fix the SACK code to print the N blocks (instead of the
647 first block N times).
649 - Don't say really small UDP packets are truncated just because they
650 aren't big enough to be a RPC. As noted by David Sacerdote.
652 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
654 - Added rfc1716 icmp codes as suggested by Martin Fredriksson

678 Thanks to John Hawkinson.
680 - Added some more packet truncation checks.
682 - On systems that have it, use sigset() instead of signal() since
683 signal() has different semantics on these systems.
685 - Fixed some more alignment problems on the alpha.
687 - Add code to massage unprintable characters in the domain and ipx
688 printers. Thanks to John Hawkinson.
690 - Added explicit netmask support. Thanks to Steve Nuchia
691 (steve@research.oknet.com)
693 - Add "sca" keyword (for DEC cluster services) as suggested by Terry
694 Kennedy (terry@spcvxa.spc.edu)
696 - Add "atalk" keyword as suggested by John Hawkinson.
698 - Added an igrp printer. Thanks to Francis Dupont
699 (francis.dupont@inria.fr)
701 - Print IPX net numbers in hex a la Novell Netware. Thanks to Terry
702 Kennedy (terry@spcvxa.spc.edu)

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

789 "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).
791 - Rewrote tcp options printer code to check for truncation. Added
792 selective acknowledgment case.
794 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
797 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
798 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
801 - Don't checksum ip header if we don't have all of it. Thanks to John
802 Hawkinson (jhawk@mit.edu).
804 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
808 v3.1a1 Wed May 3 19:21:11 PDT 1995
810 - Include time.h when SVR4 is defined to avoid problems under Solaris
813 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
814 strings, not the local buffer. Thanks to Stefan Petri
815 (petri@ibr.cs.tu-bs.de).
817 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
818 that the selected value was not used. Thanks to Pascal Hennequin
819 (Pascal.Hennequin@hugo.int-evry.fr).
821 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
823 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
825 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
827 - Although there never was a 3.0.3 release, the linux boys cleverly
828 "released" one in late 1995.
830 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
832 - Change configuration to not use gcc v2 flags with gcc v1.
834 - Redo gmt2local() so that it works under BSDI (which seems to return
835 an empty timezone struct from gettimeofday()). Based on report from
836 Terry Kennedy (terry@spcvxa.spc.edu).
838 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
839 on report from Mark Andrews (mandrews@alias.com).
841 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
842 Orth (ro@techfak.uni-bielefeld.de).

851 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
853 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
855 v3.0 Mon Jun 20 19:23:27 PDT 1994
857 - Added support for printing tcp option timestamps thanks to
858 Mark Andrews (mandrews@alias.com).
860 - Reorganize protocol dumpers to take const pointers to packets so they
861 never change the contents (i.e., they used to do endian conversions
862 in place). Previously, whenever more than one pass was taken over
863 the packet, the packet contents would be dumped incorrectly (i.e.,
864 the output form -x would be wrong on little endian machines because
865 the protocol dumpers would modify the data). Thanks to Charles Hannum
866 (mycroft@gnu.ai.mit.edu) for reporting this problem.
868 - Added support for decnet protocol dumping thanks to Jeff Mogul
871 - Fix bug that caused length of packet to be incorrectly printed
872 (off by ether header size) for unknown ethernet types thanks
873 to Greg Miller (gmiller@kayak.mitre.org).
875 - Added support for IPX protocol dumping thanks to Brad Parker
878 - Added check to verify IP header checksum under -v thanks to
879 Brad Parker (brad@fcr.com).
881 - Move packet capture code to new libpcap library (which is
882 packaged separately).
884 - Prototype everything and assume an ansi compiler.
886 - print-arp.c: Print hardware ethernet addresses if they're not
889 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
890 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
892 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
895 - print-icmp.c: Byte swap netmask before printing. Thanks to
896 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
898 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
899 By default, only the inner packet is dumped, appended with the token
900 "(encap)". Under -v, both the inner and output packets are dumped
901 (on the same line). Note that the filter applies to the original packet,
902 not the encapsulated packet. So if you run tcpdump on a net with an
903 IP Multicast tunnel, you cannot filter out the datagrams using the
904 conventional syntax. (You can filter away all the ip-in-ip traffic
905 with "not ip proto 4".)
907 - print-nfs.c: Keep pending rpc's in circular table. Add generic
908 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
910 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
912 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
913 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
914 Add && and || operators
916 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
918 - Fix bug with -c flag.
920 v2.2 Fri May 22 17:19:41 PDT 1992
922 - savefile.c: Remove hack that shouldn't have been exported. Add
925 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
926 matches non-echo/reply ICMP packets.
928 - Many improvements to filter code optimizer.
930 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
931 so that protocol qualifications are allowed. For example, "ip broadcast"
932 and "ether multicast" are valid filters.
934 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
935 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
936 patches to netinet/if_loop.c.
938 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
939 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
941 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
943 v2.1 Tue Jan 28 11:00:14 PST 1992
945 - Internal release (never publically exported).
947 v2.0.1 Sun Jan 26 21:10:10 PDT
949 - Various byte ordering fixes.
951 - Add truncation checks.
953 - inet.c: Support BSD style SIOCGIFCONF.
955 - nametoaddr.c: Handle multi addresses for single host.
957 - optimize.c: Rewritten.
959 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
962 - print-atal.c: Fix an alignment bug (thanks to
963 stanonik@nprdc.navy.mil) Add missing printf() argument.
965 - print-bootp.c: First attempt at decoding the vendor buffer.
967 - print-domain.c: Fix truncation checks.
969 - print-icmp.c: Calculate length of packets from the ip header.
971 - print-ip.c: Print frag id in decimal (so it's easier to match up
972 with non-frags). Add support for ospf, egp and igmp.
974 - print-nfs.c: Lots of changes.
976 - print-ntp.c: Make some verbose output depend on -v.
978 - print-snmp.c: New version from John LoVerso.
980 - print-tcp.c: Print rfc1072 tcp options.
982 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
983 (microseconds) worth of precision. Fix uid bugs.
985 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
986 With this option, you can create an architecture independent binary
987 trace file in real time, without the overhead of the packet printer.
988 At a later time, the packets can be filtered (again) and printed.
990 - BSD is supported. You must have BPF in your kernel.
991 Since the filtering is now done in the kernel, fewer packets are
992 dropped. In fact, with BPF and the packet dumper option, a measly
993 Sun 3/50 can keep up with a busy network.
995 - Compressed SLIP packets can now be dumped, provided you use our
996 SLIP software and BPF. These packets are dumped as any other IP
997 packet; the compressed headers are dumped with the '-e' option.
999 - Machines with little-endian byte ordering are supported (thanks to
1002 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1004 - IBM RT and Stanford Enetfilter support has been added by
1005 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1006 both the vanilla Enetfilter interface, and the extended interface
1007 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1009 - TFTP packets are now printed (requests only).
1011 - BOOTP packets are now printed.
1013 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1015 - Sparc architectures, including the Sparcstation-1, are now
1016 supported thanks to Steve McCanne and Craig Leres.
1018 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1019 University (micky@cunixc.cc.columbia.edu).
1021 - IP options are now printed.
1023 - RIP packets are now printed.
1025 - There's a -v flag that prints out more information than the
1026 default (e.g., it will enable printing of IP ttl, tos and id)
1027 and -q flag that prints out less (e.g., it will disable
1028 interpretation of AppleTalk-in-UDP).
1030 - The grammar has undergone substantial changes (if you have an
1031 earlier version of tcpdump, you should re-read the manual
1034 The most useful change is the addition of an expression
1035 syntax that lets you filter on arbitrary fields or values in the
1036 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1037 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1040 The most painful change is that concatenation no longer means
1041 "and" -- e.g., you have to say "host foo and port bar" instead
1042 of "host foo port bar". The up side to this down is that
1043 repeated qualifiers can be omitted, making most filter
1044 expressions shorter. E.g., you can now say "ip host foo and
1045 (bar or baz)" to look at ip traffic between hosts foo and bar or
1046 between hosts foo and baz. [The old way of saying this was "ip
1047 host foo and (ip host bar or ip host baz)".]
1049 v2.0 Sun Jan 13 12:20:40 PST 1991
1051 - Initial public release.
