599 autoconf version is broken (it only puts the library name in the
600 cache variable name). Thanks to John Hawkinson.
602 - Add a local autoconf macro to check for types; the autoconf version
603 is broken (it uses grep instead of actually compiling a code fragment).

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

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

704 signal() has different semantics on these systems.
706 - Fixed some more alignment problems on the alpha.
708 - Add code to massage unprintable characters in the domain and ipx
709 printers. Thanks to John Hawkinson.
711 - Added explicit netmask support. Thanks to Steve Nuchia

714 - Add "sca" keyword (for DEC cluster services) as suggested by Terry
715 Kennedy (terry@spcvxa.spc.edu)
717 - Add "atalk" keyword as suggested by John Hawkinson.
719 - Added an igrp printer. Thanks to Francis Dupont
720 (francis.dupont@inria.fr)
722 - Print IPX net numbers in hex a la Novell Netware. Thanks to Terry

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

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

872 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
874 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
876 v3.0 Mon Jun 20 19:23:27 PDT 1994
878 - Added support for printing tcp option timestamps thanks to
879 Mark Andrews (mandrews@alias.com).
881 - Reorganize protocol dumpers to take const pointers to packets so they
882 never change the contents (i.e., they used to do endian conversions
883 in place). Previously, whenever more than one pass was taken over
884 the packet, the packet contents would be dumped incorrectly (i.e.,
885 the output form -x would be wrong on little endian machines because
886 the protocol dumpers would modify the data). Thanks to Charles Hannum
887 (mycroft@gnu.ai.mit.edu) for reporting this problem.
889 - Added support for decnet protocol dumping thanks to Jeff Mogul
892 - Fix bug that caused length of packet to be incorrectly printed
893 (off by ether header size) for unknown ethernet types thanks
894 to Greg Miller (gmiller@kayak.mitre.org).
896 - Added support for IPX protocol dumping thanks to Brad Parker
899 - Added check to verify IP header checksum under -v thanks to
900 Brad Parker (brad@fcr.com).
902 - Move packet capture code to new libpcap library (which is
903 packaged separately).
905 - Prototype everything and assume an ansi compiler.
907 - print-arp.c: Print hardware ethernet addresses if they're not
910 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
911 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
913 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
916 - print-icmp.c: Byte swap netmask before printing. Thanks to
917 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
919 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
920 By default, only the inner packet is dumped, appended with the token
921 "(encap)". Under -v, both the inner and output packets are dumped
922 (on the same line). Note that the filter applies to the original packet,
923 not the encapsulated packet. So if you run tcpdump on a net with an
924 IP Multicast tunnel, you cannot filter out the datagrams using the
925 conventional syntax. (You can filter away all the ip-in-ip traffic
926 with "not ip proto 4".)
928 - print-nfs.c: Keep pending rpc's in circular table. Add generic
929 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
931 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
933 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
934 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
935 Add && and || operators
937 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
939 - Fix bug with -c flag.
941 v2.2 Fri May 22 17:19:41 PDT 1992
943 - savefile.c: Remove hack that shouldn't have been exported. Add
946 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
947 matches non-echo/reply ICMP packets.
949 - Many improvements to filter code optimizer.
951 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
952 so that protocol qualifications are allowed. For example, "ip broadcast"
953 and "ether multicast" are valid filters.
955 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
956 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
957 patches to netinet/if_loop.c.
959 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
960 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
962 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
964 v2.1 Tue Jan 28 11:00:14 PST 1992
966 - Internal release (never publically exported).
968 v2.0.1 Sun Jan 26 21:10:10 PDT
970 - Various byte ordering fixes.
972 - Add truncation checks.
974 - inet.c: Support BSD style SIOCGIFCONF.
976 - nametoaddr.c: Handle multi addresses for single host.
978 - optimize.c: Rewritten.
980 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
983 - print-atal.c: Fix an alignment bug (thanks to
984 stanonik@nprdc.navy.mil) Add missing printf() argument.
986 - print-bootp.c: First attempt at decoding the vendor buffer.
988 - print-domain.c: Fix truncation checks.
990 - print-icmp.c: Calculate length of packets from the ip header.
992 - print-ip.c: Print frag id in decimal (so it's easier to match up
993 with non-frags). Add support for ospf, egp and igmp.
995 - print-nfs.c: Lots of changes.
997 - print-ntp.c: Make some verbose output depend on -v.
999 - print-snmp.c: New version from John LoVerso.
1001 - print-tcp.c: Print rfc1072 tcp options.
1003 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1004 (microseconds) worth of precision. Fix uid bugs.
1006 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1007 With this option, you can create an architecture independent binary
1008 trace file in real time, without the overhead of the packet printer.
1009 At a later time, the packets can be filtered (again) and printed.
1011 - BSD is supported. You must have BPF in your kernel.
1012 Since the filtering is now done in the kernel, fewer packets are
1013 dropped. In fact, with BPF and the packet dumper option, a measly
1014 Sun 3/50 can keep up with a busy network.
1016 - Compressed SLIP packets can now be dumped, provided you use our
1017 SLIP software and BPF. These packets are dumped as any other IP
1018 packet; the compressed headers are dumped with the '-e' option.
1020 - Machines with little-endian byte ordering are supported (thanks to
1023 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1025 - IBM RT and Stanford Enetfilter support has been added by
1026 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1027 both the vanilla Enetfilter interface, and the extended interface
1028 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1030 - TFTP packets are now printed (requests only).
1032 - BOOTP packets are now printed.
1034 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1036 - Sparc architectures, including the Sparcstation-1, are now
1037 supported thanks to Steve McCanne and Craig Leres.
1039 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1040 University (micky@cunixc.cc.columbia.edu).
1042 - IP options are now printed.
1044 - RIP packets are now printed.
1046 - There's a -v flag that prints out more information than the
1047 default (e.g., it will enable printing of IP ttl, tos and id)
1048 and -q flag that prints out less (e.g., it will disable
1049 interpretation of AppleTalk-in-UDP).
1051 - The grammar has undergone substantial changes (if you have an
1052 earlier version of tcpdump, you should re-read the manual
1055 The most useful change is the addition of an expression
1056 syntax that lets you filter on arbitrary fields or values in the
1057 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1058 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1061 The most painful change is that concatenation no longer means
1062 "and" -- e.g., you have to say "host foo and port bar" instead
1063 of "host foo port bar". The up side to this down is that
1064 repeated qualifiers can be omitted, making most filter
1065 expressions shorter. E.g., you can now say "ip host foo and
1066 (bar or baz)" to look at ip traffic between hosts foo and bar or
1067 between hosts foo and baz. [The old way of saying this was "ip
1068 host foo and (ip host bar or ip host baz)".]
1070 v2.0 Sun Jan 13 12:20:40 PST 1991
1072 - Initial public release.
