640 formats.
641
642 - Extend OSF ip header workaround to versions 1 and 2.

694 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
695
696 - Rewrite ospf printer to improve truncation checks.
697
698 - Don't parse tcp options past the EOL. As noted by David Sacerdote
699 (davids@secnet.com). Also, check tcp options to make sure they ar
700 actually in the tcp header (in addition to the normal truncation
701 checks). Fix the SACK code to print the N blocks (instead of the
702 first block N times).
703
704 - Don't say really small UDP packets are truncated just because they
705 aren't big enough to be a RPC. As noted by David Sacerdote.
706
707 v3.2.1 Sun Jul 14 03:02:26 PDT 1996

733 Thanks to John Hawkinson.
734
735 - Added some more packet truncation checks.

791
792 - Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
793
794 - Added T/TCP options printing. As suggested by Richard Stevens

823 (cslater@imatek.com).
824
825 - Check return status from malloc/calloc/etc.
826
827 - Check return status from pcap_loop() so we can print an error and
828 exit with a bad status if there were problems.
829
830 - Bail if ip option length is <= 0. Resulted from a bug report from
831 Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).
832
833 - Print out a little more information for sun rpc packets.
834
835 - Add suport for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu).

869 strings, not the local buffer. Thanks to Stefan Petri
870 (petri@ibr.cs.tu-bs.de).
871
872 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
873 that the selected value was not used. Thanks to Pascal Hennequin
874 (Pascal.Hennequin@hugo.int-evry.fr).
875
876 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.

879
880 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
881
882 - Although there never was a 3.0.3 release, the linux boys cleverly
883 "released" one in late 1995.
884
885 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
886
887 - Change configuration to not use gcc v2 flags with gcc v1.
888
889 - Redo gmt2local() so that it works under BSDI (which seems to return
890 an empty timezone struct from gettimeofday()). Based on report from
891 Terry Kennedy (terry@spcvxa.spc.edu).
892
893 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
894 on report from Mark Andrews (mandrews@alias.com).
895
896 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
897 Orth (ro@techfak.uni-bielefeld.de).
898
899 - Fixed printout of connection id for uncompressed tcp slip packets.
900 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
901
902 - Hack around deficiency in Ultrix's make.
903
904 - Add ETHERTYPE_TRAIL define which is missing from irix5.
905
906 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
907
908 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
909
910 v3.0 Mon Jun 20 19:23:27 PDT 1994
911
912 - Added support for printing tcp option timestamps thanks to
913 Mark Andrews (mandrews@alias.com).
914
915 - Reorganize protocol dumpers to take const pointers to packets so they
916 never change the contents (i.e., they used to do endian conversions
917 in place). Previously, whenever more than one pass was taken over
918 the packet, the packet contents would be dumped incorrectly (i.e.,
919 the output form -x would be wrong on little endian machines because
920 the protocol dumpers would modify the data). Thanks to Charles Hannum
921 (mycroft@gnu.ai.mit.edu) for reporting this problem.
922
923 - Added support for decnet protocol dumping thanks to Jeff Mogul
924 (mogul@pa.dec.com).
925
926 - Fix bug that caused length of packet to be incorrectly printed
927 (off by ether header size) for unknown ethernet types thanks
928 to Greg Miller (gmiller@kayak.mitre.org).
929
930 - Added support for IPX protocol dumping thanks to Brad Parker
931 (brad@fcr.com).
932
933 - Added check to verify IP header checksum under -v thanks to
934 Brad Parker (brad@fcr.com).
935
936 - Move packet capture code to new libpcap library (which is
937 packaged separately).
938
939 - Prototype everything and assume an ansi compiler.
940
941 - print-arp.c: Print hardware ethernet addresses if they're not
942 what we expect.
943
944 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
945 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
946
947 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
948 (mogul@pa.dec.com).
949
950 - print-icmp.c: Byte swap netmask before printing. Thanks to
951 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
952
953 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
954 By default, only the inner packet is dumped, appended with the token
955 "(encap)". Under -v, both the inner and output packets are dumped
956 (on the same line). Note that the filter applies to the original packet,
957 not the encapsulated packet. So if you run tcpdump on a net with an
958 IP Multicast tunnel, you cannot filter out the datagrams using the
959 conventional syntax. (You can filter away all the ip-in-ip traffic
960 with "not ip proto 4".)
961
962 - print-nfs.c: Keep pending rpc's in circular table. Add generic
963 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
964
965 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
966
967 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
968 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
969 Add && and || operators
970
971 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
972
973 - Fix bug with -c flag.
974
975 v2.2 Fri May 22 17:19:41 PDT 1992
976
977 - savefile.c: Remove hack that shouldn't have been exported. Add
978 truncate checks.
979
980 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
981 matches non-echo/reply ICMP packets.
982
983 - Many improvements to filter code optimizer.
984
985 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
986 so that protocol qualifications are allowed. For example, "ip broadcast"
987 and "ether multicast" are valid filters.
988
989 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
990 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
991 patches to netinet/if_loop.c.
992
993 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
994 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
995
996 - Added EGP and OSPF printers, thanks to Jeffrey Honig.

1000 - Internal release (never publically exported).
1001
1002 v2.0.1 Sun Jan 26 21:10:10 PDT
1003
1004 - Various byte ordering fixes.
1005
1006 - Add truncation checks.
1007
1008 - inet.c: Support BSD style SIOCGIFCONF.
1009
1010 - nametoaddr.c: Handle multi addresses for single host.
1011
1012 - optimize.c: Rewritten.
1013
1014 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1015 for broadcast nets.
1016
1017 - print-atal.c: Fix an alignment bug (thanks to
1018 stanonik@nprdc.navy.mil) Add missing printf() argument.
1019
1020 - print-bootp.c: First attempt at decoding the vendor buffer.
1021
1022 - print-domain.c: Fix truncation checks.
1023
1024 - print-icmp.c: Calculate length of packets from the ip header.
1025
1026 - print-ip.c: Print frag id in decimal (so it's easier to match up
1027 with non-frags). Add support for ospf, egp and igmp.
1028
1029 - print-nfs.c: Lots of changes.
1030
1031 - print-ntp.c: Make some verbose output depend on -v.
1032
1033 - print-snmp.c: New version from John LoVerso.
1034
1035 - print-tcp.c: Print rfc1072 tcp options.
1036
1037 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1038 (microseconds) worth of precision. Fix uid bugs.
1039
1040 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1041 With this option, you can create an architecture independent binary
1042 trace file in real time, without the overhead of the packet printer.
1043 At a later time, the packets can be filtered (again) and printed.
1044
1045 - BSD is supported. You must have BPF in your kernel.
1046 Since the filtering is now done in the kernel, fewer packets are
1047 dropped. In fact, with BPF and the packet dumper option, a measly
1048 Sun 3/50 can keep up with a busy network.
1049
1050 - Compressed SLIP packets can now be dumped, provided you use our
1051 SLIP software and BPF. These packets are dumped as any other IP
1052 packet; the compressed headers are dumped with the '-e' option.
1053
1054 - Machines with little-endian byte ordering are supported (thanks to
1055 Jeff Mogul).
1056
1057 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1058
1059 - IBM RT and Stanford Enetfilter support has been added by
1060 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1061 both the vanilla Enetfilter interface, and the extended interface
1062 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1063
1064 - TFTP packets are now printed (requests only).
1065
1066 - BOOTP packets are now printed.
1067
1068 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1069
1070 - Sparc architectures, including the Sparcstation-1, are now
1071 supported thanks to Steve McCanne and Craig Leres.
1072
1073 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1074 University (micky@cunixc.cc.columbia.edu).
1075
1076 - IP options are now printed.
1077
1078 - RIP packets are now printed.
1079
1080 - There's a -v flag that prints out more information than the
1081 default (e.g., it will enable printing of IP ttl, tos and id)
1082 and -q flag that prints out less (e.g., it will disable
1083 interpretation of AppleTalk-in-UDP).
1084
1085 - The grammar has undergone substantial changes (if you have an
1086 earlier version of tcpdump, you should re-read the manual
1087 entry).
1088
1089 The most useful change is the addition of an expression
1090 syntax that lets you filter on arbitrary fields or values in the
1091 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1092 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1093 packets.
1094
1095 The most painful change is that concatenation no longer means
1096 "and" -- e.g., you have to say "host foo and port bar" instead
1097 of "host foo port bar". The up side to this down is that
1098 repeated qualifiers can be omitted, making most filter
1099 expressions shorter. E.g., you can now say "ip host foo and
1100 (bar or baz)" to look at ip traffic between hosts foo and bar or
1101 between hosts foo and baz. [The old way of saying this was "ip
1102 host foo and (ip host bar or ip host baz)".]
