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

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

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

873 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
876 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
877 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
880 - Don't checksum ip header if we don't have all of it. Thanks to John
881 Hawkinson (jhawk@mit.edu).
883 - Print out hostnames if possible in egp printer. Thanks to Jeffrey

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

930 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
932 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
934 v3.0 Mon Jun 20 19:23:27 PDT 1994
936 - Added support for printing tcp option timestamps thanks to
937 Mark Andrews (mandrews@alias.com).
939 - Reorganize protocol dumpers to take const pointers to packets so they
940 never change the contents (i.e., they used to do endian conversions
941 in place). Previously, whenever more than one pass was taken over
942 the packet, the packet contents would be dumped incorrectly (i.e.,
943 the output form -x would be wrong on little endian machines because
944 the protocol dumpers would modify the data). Thanks to Charles Hannum
945 (mycroft@gnu.ai.mit.edu) for reporting this problem.
947 - Added support for decnet protocol dumping thanks to Jeff Mogul
950 - Fix bug that caused length of packet to be incorrectly printed
951 (off by ether header size) for unknown ethernet types thanks
952 to Greg Miller (gmiller@kayak.mitre.org).
954 - Added support for IPX protocol dumping thanks to Brad Parker
957 - Added check to verify IP header checksum under -v thanks to
958 Brad Parker (brad@fcr.com).
960 - Move packet capture code to new libpcap library (which is
961 packaged separately).
963 - Prototype everything and assume an ansi compiler.
965 - print-arp.c: Print hardware ethernet addresses if they're not
968 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
969 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
971 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
974 - print-icmp.c: Byte swap netmask before printing. Thanks to
975 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
977 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
978 By default, only the inner packet is dumped, appended with the token
979 "(encap)". Under -v, both the inner and output packets are dumped
980 (on the same line). Note that the filter applies to the original packet,
981 not the encapsulated packet. So if you run tcpdump on a net with an
982 IP Multicast tunnel, you cannot filter out the datagrams using the
983 conventional syntax. (You can filter away all the ip-in-ip traffic
984 with "not ip proto 4".)
986 - print-nfs.c: Keep pending rpc's in circular table. Add generic
987 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
989 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
991 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
992 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
993 Add && and || operators
995 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
997 - Fix bug with -c flag.
999 v2.2 Fri May 22 17:19:41 PDT 1992
1001 - savefile.c: Remove hack that shouldn't have been exported. Add
1004 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1005 matches non-echo/reply ICMP packets.
1007 - Many improvements to filter code optimizer.
1009 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1010 so that protocol qualifications are allowed. For example, "ip broadcast"
1011 and "ether multicast" are valid filters.
1013 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1014 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1015 patches to netinet/if_loop.c.
1017 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1018 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1020 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1022 v2.1 Tue Jan 28 11:00:14 PST 1992
1024 - Internal release (never publically exported).
1026 v2.0.1 Sun Jan 26 21:10:10 PDT
1028 - Various byte ordering fixes.
1030 - Add truncation checks.
1032 - inet.c: Support BSD style SIOCGIFCONF.
1034 - nametoaddr.c: Handle multi addresses for single host.
1036 - optimize.c: Rewritten.
1038 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1041 - print-atal.c: Fix an alignment bug (thanks to
1042 stanonik@nprdc.navy.mil) Add missing printf() argument.
1044 - print-bootp.c: First attempt at decoding the vendor buffer.
1046 - print-domain.c: Fix truncation checks.
1048 - print-icmp.c: Calculate length of packets from the ip header.
1050 - print-ip.c: Print frag id in decimal (so it's easier to match up
1051 with non-frags). Add support for ospf, egp and igmp.
1053 - print-nfs.c: Lots of changes.
1055 - print-ntp.c: Make some verbose output depend on -v.
1057 - print-snmp.c: New version from John LoVerso.
1059 - print-tcp.c: Print rfc1072 tcp options.
1061 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1062 (microseconds) worth of precision. Fix uid bugs.
1064 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1065 With this option, you can create an architecture independent binary
1066 trace file in real time, without the overhead of the packet printer.
1067 At a later time, the packets can be filtered (again) and printed.
1069 - BSD is supported. You must have BPF in your kernel.
1070 Since the filtering is now done in the kernel, fewer packets are
1071 dropped. In fact, with BPF and the packet dumper option, a measly
1072 Sun 3/50 can keep up with a busy network.
1074 - Compressed SLIP packets can now be dumped, provided you use our
1075 SLIP software and BPF. These packets are dumped as any other IP
1076 packet; the compressed headers are dumped with the '-e' option.
1078 - Machines with little-endian byte ordering are supported (thanks to
1081 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1083 - IBM RT and Stanford Enetfilter support has been added by
1084 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1085 both the vanilla Enetfilter interface, and the extended interface
1086 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1088 - TFTP packets are now printed (requests only).
1090 - BOOTP packets are now printed.
1092 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1094 - Sparc architectures, including the Sparcstation-1, are now
1095 supported thanks to Steve McCanne and Craig Leres.
1097 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1098 University (micky@cunixc.cc.columbia.edu).
1100 - IP options are now printed.
1102 - RIP packets are now printed.
1104 - There's a -v flag that prints out more information than the
1105 default (e.g., it will enable printing of IP ttl, tos and id)
1106 and -q flag that prints out less (e.g., it will disable
1107 interpretation of AppleTalk-in-UDP).
1109 - The grammar has undergone substantial changes (if you have an
1110 earlier version of tcpdump, you should re-read the manual
1113 The most useful change is the addition of an expression
1114 syntax that lets you filter on arbitrary fields or values in the
1115 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1116 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1119 The most painful change is that concatenation no longer means
1120 "and" -- e.g., you have to say "host foo and port bar" instead
1121 of "host foo port bar". The up side to this down is that
1122 repeated qualifiers can be omitted, making most filter
1123 expressions shorter. E.g., you can now say "ip host foo and
1124 (bar or baz)" to look at ip traffic between hosts foo and bar or
1125 between hosts foo and baz. [The old way of saying this was "ip
1126 host foo and (ip host bar or ip host baz)".]
1128 v2.0 Sun Jan 13 12:20:40 PST 1991
1130 - Initial public release.
