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

729 (davids@secnet.com). Also, check tcp options to make sure they ar
730 actually in the tcp header (in addition to the normal truncation
731 checks). Fix the SACK code to print the N blocks (instead of the
732 first block N times).
734 - Don't say really small UDP packets are truncated just because they
735 aren't big enough to be a RPC. As noted by David Sacerdote.
737 v3.2.1 Sun Jul 14 03:02:26 PDT 1996

768 signal() has different semantics on these systems.
770 - Fixed some more alignment problems on the alpha.
772 - Add code to massage unprintable characters in the domain and ipx
773 printers. Thanks to John Hawkinson.

779 Kennedy (terry@spcvxa.spc.edu)
781 - Add "atalk" keyword as suggested by John Hawkinson.
783 - Added an igrp printer. Thanks to Francis Dupont

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

936 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
938 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
940 v3.0 Mon Jun 20 19:23:27 PDT 1994
942 - Added support for printing tcp option timestamps thanks to
943 Mark Andrews (mandrews@alias.com).
945 - Reorganize protocol dumpers to take const pointers to packets so they
946 never change the contents (i.e., they used to do endian conversions
947 in place). Previously, whenever more than one pass was taken over
948 the packet, the packet contents would be dumped incorrectly (i.e.,
949 the output form -x would be wrong on little endian machines because
950 the protocol dumpers would modify the data). Thanks to Charles Hannum
951 (mycroft@gnu.ai.mit.edu) for reporting this problem.
953 - Added support for decnet protocol dumping thanks to Jeff Mogul
956 - Fix bug that caused length of packet to be incorrectly printed
957 (off by ether header size) for unknown ethernet types thanks
958 to Greg Miller (gmiller@kayak.mitre.org).
960 - Added support for IPX protocol dumping thanks to Brad Parker
963 - Added check to verify IP header checksum under -v thanks to
964 Brad Parker (brad@fcr.com).
966 - Move packet capture code to new libpcap library (which is
967 packaged separately).
969 - Prototype everything and assume an ansi compiler.
971 - print-arp.c: Print hardware ethernet addresses if they're not
974 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
975 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
977 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
980 - print-icmp.c: Byte swap netmask before printing. Thanks to
981 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
983 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
984 By default, only the inner packet is dumped, appended with the token
985 "(encap)". Under -v, both the inner and output packets are dumped
986 (on the same line). Note that the filter applies to the original packet,
987 not the encapsulated packet. So if you run tcpdump on a net with an
988 IP Multicast tunnel, you cannot filter out the datagrams using the
989 conventional syntax. (You can filter away all the ip-in-ip traffic
990 with "not ip proto 4".)
992 - print-nfs.c: Keep pending rpc's in circular table. Add generic
993 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
995 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
997 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
998 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
999 Add && and || operators
1001 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1003 - Fix bug with -c flag.
1005 v2.2 Fri May 22 17:19:41 PDT 1992
1007 - savefile.c: Remove hack that shouldn't have been exported. Add
1010 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1011 matches non-echo/reply ICMP packets.
1013 - Many improvements to filter code optimizer.
1015 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1016 so that protocol qualifications are allowed. For example, "ip broadcast"
1017 and "ether multicast" are valid filters.
1019 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1020 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1021 patches to netinet/if_loop.c.
1023 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1024 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1026 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1028 v2.1 Tue Jan 28 11:00:14 PST 1992
1030 - Internal release (never publically exported).
1032 v2.0.1 Sun Jan 26 21:10:10 PDT
1034 - Various byte ordering fixes.
1036 - Add truncation checks.
1038 - inet.c: Support BSD style SIOCGIFCONF.
1040 - nametoaddr.c: Handle multi addresses for single host.
1042 - optimize.c: Rewritten.
1044 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1047 - print-atal.c: Fix an alignment bug (thanks to
1048 stanonik@nprdc.navy.mil) Add missing printf() argument.
1050 - print-bootp.c: First attempt at decoding the vendor buffer.
1052 - print-domain.c: Fix truncation checks.
1054 - print-icmp.c: Calculate length of packets from the ip header.
1056 - print-ip.c: Print frag id in decimal (so it's easier to match up
1057 with non-frags). Add support for ospf, egp and igmp.
1059 - print-nfs.c: Lots of changes.
1061 - print-ntp.c: Make some verbose output depend on -v.
1063 - print-snmp.c: New version from John LoVerso.
1065 - print-tcp.c: Print rfc1072 tcp options.
1067 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1068 (microseconds) worth of precision. Fix uid bugs.
1070 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1071 With this option, you can create an architecture independent binary
1072 trace file in real time, without the overhead of the packet printer.
1073 At a later time, the packets can be filtered (again) and printed.
1075 - BSD is supported. You must have BPF in your kernel.
1076 Since the filtering is now done in the kernel, fewer packets are
1077 dropped. In fact, with BPF and the packet dumper option, a measly
1078 Sun 3/50 can keep up with a busy network.
1080 - Compressed SLIP packets can now be dumped, provided you use our
1081 SLIP software and BPF. These packets are dumped as any other IP
1082 packet; the compressed headers are dumped with the '-e' option.
1084 - Machines with little-endian byte ordering are supported (thanks to
1087 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1089 - IBM RT and Stanford Enetfilter support has been added by
1090 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1091 both the vanilla Enetfilter interface, and the extended interface
1092 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1094 - TFTP packets are now printed (requests only).
1096 - BOOTP packets are now printed.
1098 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1100 - Sparc architectures, including the Sparcstation-1, are now
1101 supported thanks to Steve McCanne and Craig Leres.
1103 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1104 University (micky@cunixc.cc.columbia.edu).
1106 - IP options are now printed.
1108 - RIP packets are now printed.
1110 - There's a -v flag that prints out more information than the
1111 default (e.g., it will enable printing of IP ttl, tos and id)
1112 and -q flag that prints out less (e.g., it will disable
1113 interpretation of AppleTalk-in-UDP).
1115 - The grammar has undergone substantial changes (if you have an
1116 earlier version of tcpdump, you should re-read the manual
1119 The most useful change is the addition of an expression
1120 syntax that lets you filter on arbitrary fields or values in the
1121 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1122 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1125 The most painful change is that concatenation no longer means
1126 "and" -- e.g., you have to say "host foo and port bar" instead
1127 of "host foo port bar". The up side to this down is that
1128 repeated qualifiers can be omitted, making most filter
1129 expressions shorter. E.g., you can now say "ip host foo and
1130 (bar or baz)" to look at ip traffic between hosts foo and bar or
1131 between hosts foo and baz. [The old way of saying this was "ip
1132 host foo and (ip host bar or ip host baz)".]
1134 v2.0 Sun Jan 13 12:20:40 PST 1991
1136 - Initial public release.
