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

597 - Fix some signed problems in the nfs printer. As reported by David
598 Sacerdote (davids@silence.secnet.com)
600 - Detect group wheel and use it as the default since BSD/OS' install
601 can't hack numeric groups. Reported by David Sacerdote.

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

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

685 - Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
686 Thanks to John Hawkinson.
688 - Added some more packet truncation checks.
690 - On systems that have it, use sigset() instead of signal() since
691 signal() has different semantics on these systems.
693 - Fixed some more alignment problems on the alpha.
695 - Add code to massage unprintable characters in the domain and ipx
696 printers. Thanks to John Hawkinson.
698 - Added explicit netmask support. Thanks to Steve Nuchia
699 (steve@research.oknet.com)
701 - Add "sca" keyword (for DEC cluster services) as suggested by Terry
702 Kennedy (terry@spcvxa.spc.edu)
704 - Add "atalk" keyword as suggested by John Hawkinson.
706 - Added an igrp printer. Thanks to Francis Dupont
707 (francis.dupont@inria.fr)
709 - Print IPX net numbers in hex a la Novell Netware. Thanks to Terry
710 Kennedy (terry@spcvxa.spc.edu)

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

859 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
861 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
863 v3.0 Mon Jun 20 19:23:27 PDT 1994
865 - Added support for printing tcp option timestamps thanks to
866 Mark Andrews (mandrews@alias.com).
868 - Reorganize protocol dumpers to take const pointers to packets so they
869 never change the contents (i.e., they used to do endian conversions
870 in place). Previously, whenever more than one pass was taken over
871 the packet, the packet contents would be dumped incorrectly (i.e.,
872 the output form -x would be wrong on little endian machines because
873 the protocol dumpers would modify the data). Thanks to Charles Hannum
874 (mycroft@gnu.ai.mit.edu) for reporting this problem.
876 - Added support for decnet protocol dumping thanks to Jeff Mogul
879 - Fix bug that caused length of packet to be incorrectly printed
880 (off by ether header size) for unknown ethernet types thanks
881 to Greg Miller (gmiller@kayak.mitre.org).
883 - Added support for IPX protocol dumping thanks to Brad Parker
886 - Added check to verify IP header checksum under -v thanks to
887 Brad Parker (brad@fcr.com).
889 - Move packet capture code to new libpcap library (which is
890 packaged separately).
892 - Prototype everything and assume an ansi compiler.
894 - print-arp.c: Print hardware ethernet addresses if they're not
897 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
898 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
900 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
903 - print-icmp.c: Byte swap netmask before printing. Thanks to
904 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
906 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
907 By default, only the inner packet is dumped, appended with the token
908 "(encap)". Under -v, both the inner and output packets are dumped
909 (on the same line). Note that the filter applies to the original packet,
910 not the encapsulated packet. So if you run tcpdump on a net with an
911 IP Multicast tunnel, you cannot filter out the datagrams using the
912 conventional syntax. (You can filter away all the ip-in-ip traffic
913 with "not ip proto 4".)
915 - print-nfs.c: Keep pending rpc's in circular table. Add generic
916 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
918 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
920 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
921 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
922 Add && and || operators
924 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
926 - Fix bug with -c flag.
928 v2.2 Fri May 22 17:19:41 PDT 1992
930 - savefile.c: Remove hack that shouldn't have been exported. Add
933 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
934 matches non-echo/reply ICMP packets.
936 - Many improvements to filter code optimizer.
938 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
939 so that protocol qualifications are allowed. For example, "ip broadcast"
940 and "ether multicast" are valid filters.
942 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
943 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
944 patches to netinet/if_loop.c.
946 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
947 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
949 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
951 v2.1 Tue Jan 28 11:00:14 PST 1992
953 - Internal release (never publically exported).
955 v2.0.1 Sun Jan 26 21:10:10 PDT
957 - Various byte ordering fixes.
959 - Add truncation checks.
961 - inet.c: Support BSD style SIOCGIFCONF.
963 - nametoaddr.c: Handle multi addresses for single host.
965 - optimize.c: Rewritten.
967 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
970 - print-atal.c: Fix an alignment bug (thanks to
971 stanonik@nprdc.navy.mil) Add missing printf() argument.
973 - print-bootp.c: First attempt at decoding the vendor buffer.
975 - print-domain.c: Fix truncation checks.
977 - print-icmp.c: Calculate length of packets from the ip header.
979 - print-ip.c: Print frag id in decimal (so it's easier to match up
980 with non-frags). Add support for ospf, egp and igmp.
982 - print-nfs.c: Lots of changes.
984 - print-ntp.c: Make some verbose output depend on -v.
986 - print-snmp.c: New version from John LoVerso.
988 - print-tcp.c: Print rfc1072 tcp options.
990 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
991 (microseconds) worth of precision. Fix uid bugs.
993 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
994 With this option, you can create an architecture independent binary
995 trace file in real time, without the overhead of the packet printer.
996 At a later time, the packets can be filtered (again) and printed.
998 - BSD is supported. You must have BPF in your kernel.
999 Since the filtering is now done in the kernel, fewer packets are
1000 dropped. In fact, with BPF and the packet dumper option, a measly
1001 Sun 3/50 can keep up with a busy network.
1003 - Compressed SLIP packets can now be dumped, provided you use our
1004 SLIP software and BPF. These packets are dumped as any other IP
1005 packet; the compressed headers are dumped with the '-e' option.
1007 - Machines with little-endian byte ordering are supported (thanks to
1010 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1012 - IBM RT and Stanford Enetfilter support has been added by
1013 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1014 both the vanilla Enetfilter interface, and the extended interface
1015 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1017 - TFTP packets are now printed (requests only).
1019 - BOOTP packets are now printed.
1021 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1023 - Sparc architectures, including the Sparcstation-1, are now
1024 supported thanks to Steve McCanne and Craig Leres.
1026 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1027 University (micky@cunixc.cc.columbia.edu).
1029 - IP options are now printed.
1031 - RIP packets are now printed.
1033 - There's a -v flag that prints out more information than the
1034 default (e.g., it will enable printing of IP ttl, tos and id)
1035 and -q flag that prints out less (e.g., it will disable
1036 interpretation of AppleTalk-in-UDP).
1038 - The grammar has undergone substantial changes (if you have an
1039 earlier version of tcpdump, you should re-read the manual
1042 The most useful change is the addition of an expression
1043 syntax that lets you filter on arbitrary fields or values in the
1044 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1045 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1048 The most painful change is that concatenation no longer means
1049 "and" -- e.g., you have to say "host foo and port bar" instead
1050 of "host foo port bar". The up side to this down is that
1051 repeated qualifiers can be omitted, making most filter
1052 expressions shorter. E.g., you can now say "ip host foo and
1053 (bar or baz)" to look at ip traffic between hosts foo and bar or
1054 between hosts foo and baz. [The old way of saying this was "ip
1055 host foo and (ip host bar or ip host baz)".]
1057 v2.0 Sun Jan 13 12:20:40 PST 1991
1059 - Initial public release.
