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

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

743 - Add "sca" keyword (for DEC cluster services) as suggested by Terry
744 Kennedy (terry@spcvxa.spc.edu)
746 - Add "atalk" keyword as suggested by John Hawkinson.
748 - Added an igrp printer. Thanks to Francis Dupont
749 (francis.dupont@inria.fr)
751 - Print IPX net numbers in hex a la Novell Netware. Thanks to Terry

842 selective acknowledgment case.
844 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
847 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
848 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
851 - Don't checksum ip header if we don't have all of it. Thanks to John
852 Hawkinson (jhawk@mit.edu).
854 - Print out hostnames if possible in egp printer. Thanks to Jeffrey

864 strings, not the local buffer. Thanks to Stefan Petri
865 (petri@ibr.cs.tu-bs.de).
867 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
868 that the selected value was not used. Thanks to Pascal Hennequin
869 (Pascal.Hennequin@hugo.int-evry.fr).
871 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
873 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
875 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
877 - Although there never was a 3.0.3 release, the linux boys cleverly
878 "released" one in late 1995.
880 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
882 - Change configuration to not use gcc v2 flags with gcc v1.
884 - Redo gmt2local() so that it works under BSDI (which seems to return
885 an empty timezone struct from gettimeofday()). Based on report from
886 Terry Kennedy (terry@spcvxa.spc.edu).
888 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
889 on report from Mark Andrews (mandrews@alias.com).
891 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer

901 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
903 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
905 v3.0 Mon Jun 20 19:23:27 PDT 1994
907 - Added support for printing tcp option timestamps thanks to
908 Mark Andrews (mandrews@alias.com).
910 - Reorganize protocol dumpers to take const pointers to packets so they
911 never change the contents (i.e., they used to do endian conversions
912 in place). Previously, whenever more than one pass was taken over
913 the packet, the packet contents would be dumped incorrectly (i.e.,
914 the output form -x would be wrong on little endian machines because
915 the protocol dumpers would modify the data). Thanks to Charles Hannum
916 (mycroft@gnu.ai.mit.edu) for reporting this problem.
918 - Added support for decnet protocol dumping thanks to Jeff Mogul
921 - Fix bug that caused length of packet to be incorrectly printed
922 (off by ether header size) for unknown ethernet types thanks
923 to Greg Miller (gmiller@kayak.mitre.org).
925 - Added support for IPX protocol dumping thanks to Brad Parker
928 - Added check to verify IP header checksum under -v thanks to
929 Brad Parker (brad@fcr.com).
931 - Move packet capture code to new libpcap library (which is
932 packaged separately).
934 - Prototype everything and assume an ansi compiler.
936 - print-arp.c: Print hardware ethernet addresses if they're not
939 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
940 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
942 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
945 - print-icmp.c: Byte swap netmask before printing. Thanks to
946 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
948 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
949 By default, only the inner packet is dumped, appended with the token
950 "(encap)". Under -v, both the inner and output packets are dumped
951 (on the same line). Note that the filter applies to the original packet,
952 not the encapsulated packet. So if you run tcpdump on a net with an
953 IP Multicast tunnel, you cannot filter out the datagrams using the
954 conventional syntax. (You can filter away all the ip-in-ip traffic
955 with "not ip proto 4".)
957 - print-nfs.c: Keep pending rpc's in circular table. Add generic
958 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
960 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
962 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
963 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
964 Add && and || operators
966 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
968 - Fix bug with -c flag.
970 v2.2 Fri May 22 17:19:41 PDT 1992
972 - savefile.c: Remove hack that shouldn't have been exported. Add
975 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
976 matches non-echo/reply ICMP packets.
978 - Many improvements to filter code optimizer.
980 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
981 so that protocol qualifications are allowed. For example, "ip broadcast"
982 and "ether multicast" are valid filters.
984 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
985 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
986 patches to netinet/if_loop.c.
988 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
989 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
991 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
993 v2.1 Tue Jan 28 11:00:14 PST 1992
995 - Internal release (never publically exported).
997 v2.0.1 Sun Jan 26 21:10:10 PDT
999 - Various byte ordering fixes.
1001 - Add truncation checks.
1003 - inet.c: Support BSD style SIOCGIFCONF.
1005 - nametoaddr.c: Handle multi addresses for single host.
1007 - optimize.c: Rewritten.
1009 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1012 - print-atal.c: Fix an alignment bug (thanks to
1013 stanonik@nprdc.navy.mil) Add missing printf() argument.
1015 - print-bootp.c: First attempt at decoding the vendor buffer.
1017 - print-domain.c: Fix truncation checks.
1019 - print-icmp.c: Calculate length of packets from the ip header.
1021 - print-ip.c: Print frag id in decimal (so it's easier to match up
1022 with non-frags). Add support for ospf, egp and igmp.
1024 - print-nfs.c: Lots of changes.
1026 - print-ntp.c: Make some verbose output depend on -v.
1028 - print-snmp.c: New version from John LoVerso.
1030 - print-tcp.c: Print rfc1072 tcp options.
1032 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1033 (microseconds) worth of precision. Fix uid bugs.
1035 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1036 With this option, you can create an architecture independent binary
1037 trace file in real time, without the overhead of the packet printer.
1038 At a later time, the packets can be filtered (again) and printed.
1040 - BSD is supported. You must have BPF in your kernel.
1041 Since the filtering is now done in the kernel, fewer packets are
1042 dropped. In fact, with BPF and the packet dumper option, a measly
1043 Sun 3/50 can keep up with a busy network.
1045 - Compressed SLIP packets can now be dumped, provided you use our
1046 SLIP software and BPF. These packets are dumped as any other IP
1047 packet; the compressed headers are dumped with the '-e' option.
1049 - Machines with little-endian byte ordering are supported (thanks to
1052 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1054 - IBM RT and Stanford Enetfilter support has been added by
1055 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1056 both the vanilla Enetfilter interface, and the extended interface
1057 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1059 - TFTP packets are now printed (requests only).
1061 - BOOTP packets are now printed.
1063 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1065 - Sparc architectures, including the Sparcstation-1, are now
1066 supported thanks to Steve McCanne and Craig Leres.
1068 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1069 University (micky@cunixc.cc.columbia.edu).
1071 - IP options are now printed.
1073 - RIP packets are now printed.
1075 - There's a -v flag that prints out more information than the
1076 default (e.g., it will enable printing of IP ttl, tos and id)
1077 and -q flag that prints out less (e.g., it will disable
1078 interpretation of AppleTalk-in-UDP).
1080 - The grammar has undergone substantial changes (if you have an
1081 earlier version of tcpdump, you should re-read the manual
1084 The most useful change is the addition of an expression
1085 syntax that lets you filter on arbitrary fields or values in the
1086 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1087 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1090 The most painful change is that concatenation no longer means
1091 "and" -- e.g., you have to say "host foo and port bar" instead
1092 of "host foo port bar". The up side to this down is that
1093 repeated qualifiers can be omitted, making most filter
1094 expressions shorter. E.g., you can now say "ip host foo and
1095 (bar or baz)" to look at ip traffic between hosts foo and bar or
1096 between hosts foo and baz. [The old way of saying this was "ip
1097 host foo and (ip host bar or ip host baz)".]
1099 v2.0 Sun Jan 13 12:20:40 PST 1991
1101 - Initial public release.
