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

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

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

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

855 - Include time.h when SVR4 is defined to avoid problems under Solaris
858 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
859 strings, not the local buffer. Thanks to Stefan Petri
860 (petri@ibr.cs.tu-bs.de).
862 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
863 that the selected value was not used. Thanks to Pascal Hennequin
864 (Pascal.Hennequin@hugo.int-evry.fr).
866 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
868 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
870 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
872 - Although there never was a 3.0.3 release, the linux boys cleverly
873 "released" one in late 1995.
875 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
877 - Change configuration to not use gcc v2 flags with gcc v1.
879 - Redo gmt2local() so that it works under BSDI (which seems to return
880 an empty timezone struct from gettimeofday()). Based on report from
881 Terry Kennedy (terry@spcvxa.spc.edu).
883 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
884 on report from Mark Andrews (mandrews@alias.com).
886 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer

896 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
898 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
900 v3.0 Mon Jun 20 19:23:27 PDT 1994
902 - Added support for printing tcp option timestamps thanks to
903 Mark Andrews (mandrews@alias.com).
905 - Reorganize protocol dumpers to take const pointers to packets so they
906 never change the contents (i.e., they used to do endian conversions
907 in place). Previously, whenever more than one pass was taken over
908 the packet, the packet contents would be dumped incorrectly (i.e.,
909 the output form -x would be wrong on little endian machines because
910 the protocol dumpers would modify the data). Thanks to Charles Hannum
911 (mycroft@gnu.ai.mit.edu) for reporting this problem.
913 - Added support for decnet protocol dumping thanks to Jeff Mogul
916 - Fix bug that caused length of packet to be incorrectly printed
917 (off by ether header size) for unknown ethernet types thanks
918 to Greg Miller (gmiller@kayak.mitre.org).
920 - Added support for IPX protocol dumping thanks to Brad Parker
923 - Added check to verify IP header checksum under -v thanks to
924 Brad Parker (brad@fcr.com).
926 - Move packet capture code to new libpcap library (which is
927 packaged separately).
929 - Prototype everything and assume an ansi compiler.
931 - print-arp.c: Print hardware ethernet addresses if they're not
934 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
935 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
937 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
940 - print-icmp.c: Byte swap netmask before printing. Thanks to
941 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
943 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
944 By default, only the inner packet is dumped, appended with the token
945 "(encap)". Under -v, both the inner and output packets are dumped
946 (on the same line). Note that the filter applies to the original packet,
947 not the encapsulated packet. So if you run tcpdump on a net with an
948 IP Multicast tunnel, you cannot filter out the datagrams using the
949 conventional syntax. (You can filter away all the ip-in-ip traffic
950 with "not ip proto 4".)
952 - print-nfs.c: Keep pending rpc's in circular table. Add generic
953 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
955 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
957 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
958 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
959 Add && and || operators
961 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
963 - Fix bug with -c flag.
965 v2.2 Fri May 22 17:19:41 PDT 1992
967 - savefile.c: Remove hack that shouldn't have been exported. Add
970 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
971 matches non-echo/reply ICMP packets.
973 - Many improvements to filter code optimizer.
975 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
976 so that protocol qualifications are allowed. For example, "ip broadcast"
977 and "ether multicast" are valid filters.
979 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
980 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
981 patches to netinet/if_loop.c.
983 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
984 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
986 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
988 v2.1 Tue Jan 28 11:00:14 PST 1992
990 - Internal release (never publically exported).
992 v2.0.1 Sun Jan 26 21:10:10 PDT
994 - Various byte ordering fixes.
996 - Add truncation checks.
998 - inet.c: Support BSD style SIOCGIFCONF.
1000 - nametoaddr.c: Handle multi addresses for single host.
1002 - optimize.c: Rewritten.
1004 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1007 - print-atal.c: Fix an alignment bug (thanks to
1008 stanonik@nprdc.navy.mil) Add missing printf() argument.
1010 - print-bootp.c: First attempt at decoding the vendor buffer.
1012 - print-domain.c: Fix truncation checks.
1014 - print-icmp.c: Calculate length of packets from the ip header.
1016 - print-ip.c: Print frag id in decimal (so it's easier to match up
1017 with non-frags). Add support for ospf, egp and igmp.
1019 - print-nfs.c: Lots of changes.
1021 - print-ntp.c: Make some verbose output depend on -v.
1023 - print-snmp.c: New version from John LoVerso.
1025 - print-tcp.c: Print rfc1072 tcp options.
1027 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1028 (microseconds) worth of precision. Fix uid bugs.
1030 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1031 With this option, you can create an architecture independent binary
1032 trace file in real time, without the overhead of the packet printer.
1033 At a later time, the packets can be filtered (again) and printed.
1035 - BSD is supported. You must have BPF in your kernel.
1036 Since the filtering is now done in the kernel, fewer packets are
1037 dropped. In fact, with BPF and the packet dumper option, a measly
1038 Sun 3/50 can keep up with a busy network.
1040 - Compressed SLIP packets can now be dumped, provided you use our
1041 SLIP software and BPF. These packets are dumped as any other IP
1042 packet; the compressed headers are dumped with the '-e' option.
1044 - Machines with little-endian byte ordering are supported (thanks to
1047 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1049 - IBM RT and Stanford Enetfilter support has been added by
1050 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1051 both the vanilla Enetfilter interface, and the extended interface
1052 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1054 - TFTP packets are now printed (requests only).
1056 - BOOTP packets are now printed.
1058 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1060 - Sparc architectures, including the Sparcstation-1, are now
1061 supported thanks to Steve McCanne and Craig Leres.
1063 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1064 University (micky@cunixc.cc.columbia.edu).
1066 - IP options are now printed.
1068 - RIP packets are now printed.
1070 - There's a -v flag that prints out more information than the
1071 default (e.g., it will enable printing of IP ttl, tos and id)
1072 and -q flag that prints out less (e.g., it will disable
1073 interpretation of AppleTalk-in-UDP).
1075 - The grammar has undergone substantial changes (if you have an
1076 earlier version of tcpdump, you should re-read the manual
1079 The most useful change is the addition of an expression
1080 syntax that lets you filter on arbitrary fields or values in the
1081 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1082 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1085 The most painful change is that concatenation no longer means
1086 "and" -- e.g., you have to say "host foo and port bar" instead
1087 of "host foo port bar". The up side to this down is that
1088 repeated qualifiers can be omitted, making most filter
1089 expressions shorter. E.g., you can now say "ip host foo and
1090 (bar or baz)" to look at ip traffic between hosts foo and bar or
1091 between hosts foo and baz. [The old way of saying this was "ip
1092 host foo and (ip host bar or ip host baz)".]
1094 v2.0 Sun Jan 13 12:20:40 PST 1991
1096 - Initial public release.
