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

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

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

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

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

905 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
907 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
909 v3.0 Mon Jun 20 19:23:27 PDT 1994
911 - Added support for printing tcp option timestamps thanks to
912 Mark Andrews (mandrews@alias.com).
914 - Reorganize protocol dumpers to take const pointers to packets so they
915 never change the contents (i.e., they used to do endian conversions
916 in place). Previously, whenever more than one pass was taken over
917 the packet, the packet contents would be dumped incorrectly (i.e.,
918 the output form -x would be wrong on little endian machines because
919 the protocol dumpers would modify the data). Thanks to Charles Hannum
920 (mycroft@gnu.ai.mit.edu) for reporting this problem.
922 - Added support for decnet protocol dumping thanks to Jeff Mogul
925 - Fix bug that caused length of packet to be incorrectly printed
926 (off by ether header size) for unknown ethernet types thanks
927 to Greg Miller (gmiller@kayak.mitre.org).
929 - Added support for IPX protocol dumping thanks to Brad Parker
932 - Added check to verify IP header checksum under -v thanks to
933 Brad Parker (brad@fcr.com).
935 - Move packet capture code to new libpcap library (which is
936 packaged separately).
938 - Prototype everything and assume an ansi compiler.
940 - print-arp.c: Print hardware ethernet addresses if they're not
943 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
944 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
946 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
949 - print-icmp.c: Byte swap netmask before printing. Thanks to
950 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
952 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
953 By default, only the inner packet is dumped, appended with the token
954 "(encap)". Under -v, both the inner and output packets are dumped
955 (on the same line). Note that the filter applies to the original packet,
956 not the encapsulated packet. So if you run tcpdump on a net with an
957 IP Multicast tunnel, you cannot filter out the datagrams using the
958 conventional syntax. (You can filter away all the ip-in-ip traffic
959 with "not ip proto 4".)
961 - print-nfs.c: Keep pending rpc's in circular table. Add generic
962 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
964 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
966 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
967 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
968 Add && and || operators
970 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
972 - Fix bug with -c flag.
974 v2.2 Fri May 22 17:19:41 PDT 1992
976 - savefile.c: Remove hack that shouldn't have been exported. Add
979 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
980 matches non-echo/reply ICMP packets.
982 - Many improvements to filter code optimizer.
984 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
985 so that protocol qualifications are allowed. For example, "ip broadcast"
986 and "ether multicast" are valid filters.
988 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
989 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
990 patches to netinet/if_loop.c.
992 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
993 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
995 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
997 v2.1 Tue Jan 28 11:00:14 PST 1992
999 - Internal release (never publically exported).
1001 v2.0.1 Sun Jan 26 21:10:10 PDT
1003 - Various byte ordering fixes.
1005 - Add truncation checks.
1007 - inet.c: Support BSD style SIOCGIFCONF.
1009 - nametoaddr.c: Handle multi addresses for single host.
1011 - optimize.c: Rewritten.
1013 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1016 - print-atal.c: Fix an alignment bug (thanks to
1017 stanonik@nprdc.navy.mil) Add missing printf() argument.
1019 - print-bootp.c: First attempt at decoding the vendor buffer.
1021 - print-domain.c: Fix truncation checks.
1023 - print-icmp.c: Calculate length of packets from the ip header.
1025 - print-ip.c: Print frag id in decimal (so it's easier to match up
1026 with non-frags). Add support for ospf, egp and igmp.
1028 - print-nfs.c: Lots of changes.
1030 - print-ntp.c: Make some verbose output depend on -v.
1032 - print-snmp.c: New version from John LoVerso.
1034 - print-tcp.c: Print rfc1072 tcp options.
1036 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1037 (microseconds) worth of precision. Fix uid bugs.
1039 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1040 With this option, you can create an architecture independent binary
1041 trace file in real time, without the overhead of the packet printer.
1042 At a later time, the packets can be filtered (again) and printed.
1044 - BSD is supported. You must have BPF in your kernel.
1045 Since the filtering is now done in the kernel, fewer packets are
1046 dropped. In fact, with BPF and the packet dumper option, a measly
1047 Sun 3/50 can keep up with a busy network.
1049 - Compressed SLIP packets can now be dumped, provided you use our
1050 SLIP software and BPF. These packets are dumped as any other IP
1051 packet; the compressed headers are dumped with the '-e' option.
1053 - Machines with little-endian byte ordering are supported (thanks to
1056 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1058 - IBM RT and Stanford Enetfilter support has been added by
1059 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1060 both the vanilla Enetfilter interface, and the extended interface
1061 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1063 - TFTP packets are now printed (requests only).
1065 - BOOTP packets are now printed.
1067 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1069 - Sparc architectures, including the Sparcstation-1, are now
1070 supported thanks to Steve McCanne and Craig Leres.
1072 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1073 University (micky@cunixc.cc.columbia.edu).
1075 - IP options are now printed.
1077 - RIP packets are now printed.
1079 - There's a -v flag that prints out more information than the
1080 default (e.g., it will enable printing of IP ttl, tos and id)
1081 and -q flag that prints out less (e.g., it will disable
1082 interpretation of AppleTalk-in-UDP).
1084 - The grammar has undergone substantial changes (if you have an
1085 earlier version of tcpdump, you should re-read the manual
1088 The most useful change is the addition of an expression
1089 syntax that lets you filter on arbitrary fields or values in the
1090 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1091 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1094 The most painful change is that concatenation no longer means
1095 "and" -- e.g., you have to say "host foo and port bar" instead
1096 of "host foo port bar". The up side to this down is that
1097 repeated qualifiers can be omitted, making most filter
1098 expressions shorter. E.g., you can now say "ip host foo and
1099 (bar or baz)" to look at ip traffic between hosts foo and bar or
1100 between hosts foo and baz. [The old way of saying this was "ip
1101 host foo and (ip host bar or ip host baz)".]
1103 v2.0 Sun Jan 13 12:20:40 PST 1991
1105 - Initial public release.
