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

750 Thanks to John Hawkinson.
752 - Added some more packet truncation checks.
754 - On systems that have it, use sigset() instead of signal() since
755 signal() has different semantics on these systems.
757 - Fixed some more alignment problems on the alpha.
759 - Add code to massage unprintable characters in the domain and ipx
760 printers. Thanks to John Hawkinson.

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

870 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
873 - Don't checksum ip header if we don't have all of it. Thanks to John
874 Hawkinson (jhawk@mit.edu).
876 - Print out hostnames if possible in egp printer. Thanks to Jeffrey

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

923 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
925 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
927 v3.0 Mon Jun 20 19:23:27 PDT 1994
929 - Added support for printing tcp option timestamps thanks to
930 Mark Andrews (mandrews@alias.com).
932 - Reorganize protocol dumpers to take const pointers to packets so they
933 never change the contents (i.e., they used to do endian conversions
934 in place). Previously, whenever more than one pass was taken over
935 the packet, the packet contents would be dumped incorrectly (i.e.,
936 the output form -x would be wrong on little endian machines because
937 the protocol dumpers would modify the data). Thanks to Charles Hannum
938 (mycroft@gnu.ai.mit.edu) for reporting this problem.
940 - Added support for decnet protocol dumping thanks to Jeff Mogul
943 - Fix bug that caused length of packet to be incorrectly printed
944 (off by ether header size) for unknown ethernet types thanks
945 to Greg Miller (gmiller@kayak.mitre.org).
947 - Added support for IPX protocol dumping thanks to Brad Parker
950 - Added check to verify IP header checksum under -v thanks to
951 Brad Parker (brad@fcr.com).
953 - Move packet capture code to new libpcap library (which is
954 packaged separately).
956 - Prototype everything and assume an ansi compiler.
958 - print-arp.c: Print hardware ethernet addresses if they're not
961 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
962 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
964 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
967 - print-icmp.c: Byte swap netmask before printing. Thanks to
968 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
970 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
971 By default, only the inner packet is dumped, appended with the token
972 "(encap)". Under -v, both the inner and output packets are dumped
973 (on the same line). Note that the filter applies to the original packet,
974 not the encapsulated packet. So if you run tcpdump on a net with an
975 IP Multicast tunnel, you cannot filter out the datagrams using the
976 conventional syntax. (You can filter away all the ip-in-ip traffic
977 with "not ip proto 4".)
979 - print-nfs.c: Keep pending rpc's in circular table. Add generic
980 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
982 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
984 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
985 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
986 Add && and || operators
988 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
990 - Fix bug with -c flag.
992 v2.2 Fri May 22 17:19:41 PDT 1992
994 - savefile.c: Remove hack that shouldn't have been exported. Add
997 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
998 matches non-echo/reply ICMP packets.
1000 - Many improvements to filter code optimizer.
1002 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1003 so that protocol qualifications are allowed. For example, "ip broadcast"
1004 and "ether multicast" are valid filters.
1006 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1007 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1008 patches to netinet/if_loop.c.
1010 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1011 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1013 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1015 v2.1 Tue Jan 28 11:00:14 PST 1992
1017 - Internal release (never publically exported).
1019 v2.0.1 Sun Jan 26 21:10:10 PDT
1021 - Various byte ordering fixes.
1023 - Add truncation checks.
1025 - inet.c: Support BSD style SIOCGIFCONF.
1027 - nametoaddr.c: Handle multi addresses for single host.
1029 - optimize.c: Rewritten.
1031 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1034 - print-atal.c: Fix an alignment bug (thanks to
1035 stanonik@nprdc.navy.mil) Add missing printf() argument.
1037 - print-bootp.c: First attempt at decoding the vendor buffer.
1039 - print-domain.c: Fix truncation checks.
1041 - print-icmp.c: Calculate length of packets from the ip header.
1043 - print-ip.c: Print frag id in decimal (so it's easier to match up
1044 with non-frags). Add support for ospf, egp and igmp.
1046 - print-nfs.c: Lots of changes.
1048 - print-ntp.c: Make some verbose output depend on -v.
1050 - print-snmp.c: New version from John LoVerso.
1052 - print-tcp.c: Print rfc1072 tcp options.
1054 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1055 (microseconds) worth of precision. Fix uid bugs.
1057 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1058 With this option, you can create an architecture independent binary
1059 trace file in real time, without the overhead of the packet printer.
1060 At a later time, the packets can be filtered (again) and printed.
1062 - BSD is supported. You must have BPF in your kernel.
1063 Since the filtering is now done in the kernel, fewer packets are
1064 dropped. In fact, with BPF and the packet dumper option, a measly
1065 Sun 3/50 can keep up with a busy network.
1067 - Compressed SLIP packets can now be dumped, provided you use our
1068 SLIP software and BPF. These packets are dumped as any other IP
1069 packet; the compressed headers are dumped with the '-e' option.
1071 - Machines with little-endian byte ordering are supported (thanks to
1074 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1076 - IBM RT and Stanford Enetfilter support has been added by
1077 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1078 both the vanilla Enetfilter interface, and the extended interface
1079 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1081 - TFTP packets are now printed (requests only).
1083 - BOOTP packets are now printed.
1085 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1087 - Sparc architectures, including the Sparcstation-1, are now
1088 supported thanks to Steve McCanne and Craig Leres.
1090 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1091 University (micky@cunixc.cc.columbia.edu).
1093 - IP options are now printed.
1095 - RIP packets are now printed.
1097 - There's a -v flag that prints out more information than the
1098 default (e.g., it will enable printing of IP ttl, tos and id)
1099 and -q flag that prints out less (e.g., it will disable
1100 interpretation of AppleTalk-in-UDP).
1102 - The grammar has undergone substantial changes (if you have an
1103 earlier version of tcpdump, you should re-read the manual
1106 The most useful change is the addition of an expression
1107 syntax that lets you filter on arbitrary fields or values in the
1108 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1109 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1112 The most painful change is that concatenation no longer means
1113 "and" -- e.g., you have to say "host foo and port bar" instead
1114 of "host foo port bar". The up side to this down is that
1115 repeated qualifiers can be omitted, making most filter
1116 expressions shorter. E.g., you can now say "ip host foo and
1117 (bar or baz)" to look at ip traffic between hosts foo and bar or
1118 between hosts foo and baz. [The old way of saying this was "ip
1119 host foo and (ip host bar or ip host baz)".]
1121 v2.0 Sun Jan 13 12:20:40 PST 1991
1123 - Initial public release.
