698 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
700 - Rewrite ospf printer to improve truncation checks.

703 (davids@secnet.com). Also, check tcp options to make sure they ar
704 actually in the tcp header (in addition to the normal truncation
705 checks). Fix the SACK code to print the N blocks (instead of the
706 first block N times).
708 - Don't say really small UDP packets are truncated just because they
709 aren't big enough to be a RPC. As noted by David Sacerdote.
711 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
713 - Added rfc1716 icmp codes as suggested by Martin Fredriksson

737 Thanks to John Hawkinson.
739 - Added some more packet truncation checks.
741 - On systems that have it, use sigset() instead of signal() since
742 signal() has different semantics on these systems.
744 - Fixed some more alignment problems on the alpha.
746 - Add code to massage unprintable characters in the domain and ipx
747 printers. Thanks to John Hawkinson.
749 - Added explicit netmask support. Thanks to Steve Nuchia

752 - Add "sca" keyword (for DEC cluster services) as suggested by Terry
753 Kennedy (terry@spcvxa.spc.edu)
755 - Add "atalk" keyword as suggested by John Hawkinson.
757 - Added an igrp printer. Thanks to Francis Dupont
758 (francis.dupont@inria.fr)
760 - Print IPX net numbers in hex a la Novell Netware. Thanks to Terry
761 Kennedy (terry@spcvxa.spc.edu)

851 selective acknowledgment case.
853 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
856 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
857 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
860 - Don't checksum ip header if we don't have all of it. Thanks to John
861 Hawkinson (jhawk@mit.edu).
863 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
867 v3.1a1 Wed May 3 19:21:11 PDT 1995
869 - Include time.h when SVR4 is defined to avoid problems under Solaris
872 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
873 strings, not the local buffer. Thanks to Stefan Petri
874 (petri@ibr.cs.tu-bs.de).
876 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
877 that the selected value was not used. Thanks to Pascal Hennequin
878 (Pascal.Hennequin@hugo.int-evry.fr).
880 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
882 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
884 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
886 - Although there never was a 3.0.3 release, the linux boys cleverly
887 "released" one in late 1995.
889 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
891 - Change configuration to not use gcc v2 flags with gcc v1.
893 - Redo gmt2local() so that it works under BSDI (which seems to return
894 an empty timezone struct from gettimeofday()). Based on report from
895 Terry Kennedy (terry@spcvxa.spc.edu).
897 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
898 on report from Mark Andrews (mandrews@alias.com).
900 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
901 Orth (ro@techfak.uni-bielefeld.de).

910 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
912 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
914 v3.0 Mon Jun 20 19:23:27 PDT 1994
916 - Added support for printing tcp option timestamps thanks to
917 Mark Andrews (mandrews@alias.com).
919 - Reorganize protocol dumpers to take const pointers to packets so they
920 never change the contents (i.e., they used to do endian conversions
921 in place). Previously, whenever more than one pass was taken over
922 the packet, the packet contents would be dumped incorrectly (i.e.,
923 the output form -x would be wrong on little endian machines because
924 the protocol dumpers would modify the data). Thanks to Charles Hannum
925 (mycroft@gnu.ai.mit.edu) for reporting this problem.
927 - Added support for decnet protocol dumping thanks to Jeff Mogul
930 - Fix bug that caused length of packet to be incorrectly printed
931 (off by ether header size) for unknown ethernet types thanks
932 to Greg Miller (gmiller@kayak.mitre.org).
934 - Added support for IPX protocol dumping thanks to Brad Parker
937 - Added check to verify IP header checksum under -v thanks to
938 Brad Parker (brad@fcr.com).
940 - Move packet capture code to new libpcap library (which is
941 packaged separately).
943 - Prototype everything and assume an ansi compiler.
945 - print-arp.c: Print hardware ethernet addresses if they're not
948 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
949 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
951 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
954 - print-icmp.c: Byte swap netmask before printing. Thanks to
955 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
957 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
958 By default, only the inner packet is dumped, appended with the token
959 "(encap)". Under -v, both the inner and output packets are dumped
960 (on the same line). Note that the filter applies to the original packet,
961 not the encapsulated packet. So if you run tcpdump on a net with an
962 IP Multicast tunnel, you cannot filter out the datagrams using the
963 conventional syntax. (You can filter away all the ip-in-ip traffic
964 with "not ip proto 4".)
966 - print-nfs.c: Keep pending rpc's in circular table. Add generic
967 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
969 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
971 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
972 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
973 Add && and || operators
975 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
977 - Fix bug with -c flag.
979 v2.2 Fri May 22 17:19:41 PDT 1992
981 - savefile.c: Remove hack that shouldn't have been exported. Add
984 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
985 matches non-echo/reply ICMP packets.
987 - Many improvements to filter code optimizer.
989 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
990 so that protocol qualifications are allowed. For example, "ip broadcast"
991 and "ether multicast" are valid filters.
993 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
994 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
995 patches to netinet/if_loop.c.
997 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
998 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1000 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1002 v2.1 Tue Jan 28 11:00:14 PST 1992
1004 - Internal release (never publically exported).
1006 v2.0.1 Sun Jan 26 21:10:10 PDT
1008 - Various byte ordering fixes.
1010 - Add truncation checks.
1012 - inet.c: Support BSD style SIOCGIFCONF.
1014 - nametoaddr.c: Handle multi addresses for single host.
1016 - optimize.c: Rewritten.
1018 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1021 - print-atal.c: Fix an alignment bug (thanks to
1022 stanonik@nprdc.navy.mil) Add missing printf() argument.
1024 - print-bootp.c: First attempt at decoding the vendor buffer.
1026 - print-domain.c: Fix truncation checks.
1028 - print-icmp.c: Calculate length of packets from the ip header.
1030 - print-ip.c: Print frag id in decimal (so it's easier to match up
1031 with non-frags). Add support for ospf, egp and igmp.
1033 - print-nfs.c: Lots of changes.
1035 - print-ntp.c: Make some verbose output depend on -v.
1037 - print-snmp.c: New version from John LoVerso.
1039 - print-tcp.c: Print rfc1072 tcp options.
1041 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1042 (microseconds) worth of precision. Fix uid bugs.
1044 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1045 With this option, you can create an architecture independent binary
1046 trace file in real time, without the overhead of the packet printer.
1047 At a later time, the packets can be filtered (again) and printed.
1049 - BSD is supported. You must have BPF in your kernel.
1050 Since the filtering is now done in the kernel, fewer packets are
1051 dropped. In fact, with BPF and the packet dumper option, a measly
1052 Sun 3/50 can keep up with a busy network.
1054 - Compressed SLIP packets can now be dumped, provided you use our
1055 SLIP software and BPF. These packets are dumped as any other IP
1056 packet; the compressed headers are dumped with the '-e' option.
1058 - Machines with little-endian byte ordering are supported (thanks to
1061 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1063 - IBM RT and Stanford Enetfilter support has been added by
1064 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1065 both the vanilla Enetfilter interface, and the extended interface
1066 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1068 - TFTP packets are now printed (requests only).
1070 - BOOTP packets are now printed.
1072 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1074 - Sparc architectures, including the Sparcstation-1, are now
1075 supported thanks to Steve McCanne and Craig Leres.
1077 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1078 University (micky@cunixc.cc.columbia.edu).
1080 - IP options are now printed.
1082 - RIP packets are now printed.
1084 - There's a -v flag that prints out more information than the
1085 default (e.g., it will enable printing of IP ttl, tos and id)
1086 and -q flag that prints out less (e.g., it will disable
1087 interpretation of AppleTalk-in-UDP).
1089 - The grammar has undergone substantial changes (if you have an
1090 earlier version of tcpdump, you should re-read the manual
1093 The most useful change is the addition of an expression
1094 syntax that lets you filter on arbitrary fields or values in the
1095 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1096 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1099 The most painful change is that concatenation no longer means
1100 "and" -- e.g., you have to say "host foo and port bar" instead
1101 of "host foo port bar". The up side to this down is that
1102 repeated qualifiers can be omitted, making most filter
1103 expressions shorter. E.g., you can now say "ip host foo and
1104 (bar or baz)" to look at ip traffic between hosts foo and bar or
1105 between hosts foo and baz. [The old way of saying this was "ip
1106 host foo and (ip host bar or ip host baz)".]
1108 v2.0 Sun Jan 13 12:20:40 PST 1991
1110 - Initial public release.
