577 Marty Leisner (leisner@sdsp.mc.xerox.com)
579 - Add a local autoconf macro to check for routines in libraries; the
580 autoconf version is broken (it only puts the library name in the
581 cache variable name). Thanks to John Hawkinson.
583 - Add a local autoconf macro to check for types; the autoconf version
584 is broken (it uses grep instead of actually compiling a code fragment).
586 - Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header

591 - Fix some signed problems in the nfs printer. As reported by David
592 Sacerdote (davids@silence.secnet.com)
594 - Detect group wheel and use it as the default since BSD/OS' install
595 can't hack numeric groups. Reported by David Sacerdote.
597 - AIX needs special loader options. Thanks to Jonathan I. Kamens

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

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

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

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

853 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
855 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
857 v3.0 Mon Jun 20 19:23:27 PDT 1994
859 - Added support for printing tcp option timestamps thanks to
860 Mark Andrews (mandrews@alias.com).
862 - Reorganize protocol dumpers to take const pointers to packets so they
863 never change the contents (i.e., they used to do endian conversions
864 in place). Previously, whenever more than one pass was taken over
865 the packet, the packet contents would be dumped incorrectly (i.e.,
866 the output form -x would be wrong on little endian machines because
867 the protocol dumpers would modify the data). Thanks to Charles Hannum
868 (mycroft@gnu.ai.mit.edu) for reporting this problem.
870 - Added support for decnet protocol dumping thanks to Jeff Mogul
873 - Fix bug that caused length of packet to be incorrectly printed
874 (off by ether header size) for unknown ethernet types thanks
875 to Greg Miller (gmiller@kayak.mitre.org).
877 - Added support for IPX protocol dumping thanks to Brad Parker
880 - Added check to verify IP header checksum under -v thanks to
881 Brad Parker (brad@fcr.com).
883 - Move packet capture code to new libpcap library (which is
884 packaged separately).
886 - Prototype everything and assume an ansi compiler.
888 - print-arp.c: Print hardware ethernet addresses if they're not
891 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
892 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
894 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
897 - print-icmp.c: Byte swap netmask before printing. Thanks to
898 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
900 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
901 By default, only the inner packet is dumped, appended with the token
902 "(encap)". Under -v, both the inner and output packets are dumped
903 (on the same line). Note that the filter applies to the original packet,
904 not the encapsulated packet. So if you run tcpdump on a net with an
905 IP Multicast tunnel, you cannot filter out the datagrams using the
906 conventional syntax. (You can filter away all the ip-in-ip traffic
907 with "not ip proto 4".)
909 - print-nfs.c: Keep pending rpc's in circular table. Add generic
910 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
912 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
914 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
915 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
916 Add && and || operators
918 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
920 - Fix bug with -c flag.
922 v2.2 Fri May 22 17:19:41 PDT 1992
924 - savefile.c: Remove hack that shouldn't have been exported. Add
927 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
928 matches non-echo/reply ICMP packets.
930 - Many improvements to filter code optimizer.
932 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
933 so that protocol qualifications are allowed. For example, "ip broadcast"
934 and "ether multicast" are valid filters.
936 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
937 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
938 patches to netinet/if_loop.c.
940 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
941 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
943 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
945 v2.1 Tue Jan 28 11:00:14 PST 1992
947 - Internal release (never publically exported).
949 v2.0.1 Sun Jan 26 21:10:10 PDT
951 - Various byte ordering fixes.
953 - Add truncation checks.
955 - inet.c: Support BSD style SIOCGIFCONF.
957 - nametoaddr.c: Handle multi addresses for single host.
959 - optimize.c: Rewritten.
961 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
964 - print-atal.c: Fix an alignment bug (thanks to
965 stanonik@nprdc.navy.mil) Add missing printf() argument.
967 - print-bootp.c: First attempt at decoding the vendor buffer.
969 - print-domain.c: Fix truncation checks.
971 - print-icmp.c: Calculate length of packets from the ip header.
973 - print-ip.c: Print frag id in decimal (so it's easier to match up
974 with non-frags). Add support for ospf, egp and igmp.
976 - print-nfs.c: Lots of changes.
978 - print-ntp.c: Make some verbose output depend on -v.
980 - print-snmp.c: New version from John LoVerso.
982 - print-tcp.c: Print rfc1072 tcp options.
984 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
985 (microseconds) worth of precision. Fix uid bugs.
987 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
988 With this option, you can create an architecture independent binary
989 trace file in real time, without the overhead of the packet printer.
990 At a later time, the packets can be filtered (again) and printed.
992 - BSD is supported. You must have BPF in your kernel.
993 Since the filtering is now done in the kernel, fewer packets are
994 dropped. In fact, with BPF and the packet dumper option, a measly
995 Sun 3/50 can keep up with a busy network.
997 - Compressed SLIP packets can now be dumped, provided you use our
998 SLIP software and BPF. These packets are dumped as any other IP
999 packet; the compressed headers are dumped with the '-e' option.
1001 - Machines with little-endian byte ordering are supported (thanks to
1004 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1006 - IBM RT and Stanford Enetfilter support has been added by
1007 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1008 both the vanilla Enetfilter interface, and the extended interface
1009 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1011 - TFTP packets are now printed (requests only).
1013 - BOOTP packets are now printed.
1015 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1017 - Sparc architectures, including the Sparcstation-1, are now
1018 supported thanks to Steve McCanne and Craig Leres.
1020 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1021 University (micky@cunixc.cc.columbia.edu).
1023 - IP options are now printed.
1025 - RIP packets are now printed.
1027 - There's a -v flag that prints out more information than the
1028 default (e.g., it will enable printing of IP ttl, tos and id)
1029 and -q flag that prints out less (e.g., it will disable
1030 interpretation of AppleTalk-in-UDP).
1032 - The grammar has undergone substantial changes (if you have an
1033 earlier version of tcpdump, you should re-read the manual
1036 The most useful change is the addition of an expression
1037 syntax that lets you filter on arbitrary fields or values in the
1038 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1039 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1042 The most painful change is that concatenation no longer means
1043 "and" -- e.g., you have to say "host foo and port bar" instead
1044 of "host foo port bar". The up side to this down is that
1045 repeated qualifiers can be omitted, making most filter
1046 expressions shorter. E.g., you can now say "ip host foo and
1047 (bar or baz)" to look at ip traffic between hosts foo and bar or
1048 between hosts foo and baz. [The old way of saying this was "ip
1049 host foo and (ip host bar or ip host baz)".]
1051 v2.0 Sun Jan 13 12:20:40 PST 1991
1053 - Initial public release.
