 702
 703 - GRE encapsulated packet printer thanks to John Hawkinson
 704   (jhawk@mit.edu)
 705
 706 - Rewrite gmt2local() to avoid problematic os dependencies.
 707
 708 - Suppress nfs truncation message on errors.
 709
 710 - Add missing m4 quoting in AC_LBL_UNALIGNED_ACCESS autoconf macro.
 711   Reported by Joachim Ott (ott@ardala.han.de)
 712
 713 - Enable "ip_hl vs. ip_vhl" workaround for OSF4 too.
 714
 715 - Print arp hardware type in host order. Thanks to Onno van der Linden
 716   (onno@simplex.nl)
 717
 718 - Avoid solaris compiler warnings. Thanks to Bruce Barnett
 719   (barnett@grymoire.crd.ge.com)
 720
 721 - Fix rip printer to not print one more route than is actually in the
 722   packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
 723   Bill Fenner (fenner@parc.xerox.com)
 724
 725 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
 726
 727 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
 728   Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
 729
 730 - Rewrite ospf printer to improve truncation checks.
 731
 732 - Don't parse tcp options past the EOL. As noted by David Sacerdote
 733   (davids@secnet.com). Also, check tcp options to make sure they ar
 734   actually in the tcp header (in addition to the normal truncation
 735   checks). Fix the SACK code to print the N blocks (instead of the
 736   first block N times).
 737
 738 - Don't say really small UDP packets are truncated just because they
 739   aren't big enough to be a RPC. As noted by David Sacerdote.
 740
 741 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
 742

 753   (kushida@trl.ibm.co.jp)
 754
 755 - Check igmp checksum if possible. Thanks to John Hawkinson.

 767   Thanks to John Hawkinson.
 768
 769 - Added some more packet truncation checks.
 770
 771 - On systems that have it, use sigset() instead of signal() since

 773
 774 - Fixed some more alignment problems on the alpha.
 775
 776 - Add code to massage unprintable characters in the domain and ipx

 790 - Print IPX net numbers in hex a la Novell Netware. Thanks to Terry
 791   Kennedy (terry@spcvxa.spc.edu)
 792
 793 - Fixed snmp extended tag field parsing bug. Thanks to Pascal Hennequin
 794   (pascal.hennequin@hugo.int-evry.fr)

 796 - Added some ETHERTYPEs missing on some systems.
 797
 798 - Added truncated packet macros and various checks.
 799
 800 - Fixed endian problems with the DECnet printer.
 801
 802 - Use $CC when checking gcc version. Thanks to Carl Lindberg
 803   (carl_lindberg@blacksmith.com)
 804
 805 - Fixes for AIX (although this system is not yet supported). Thanks to
 806   John Hawkinson.
 807
 808 - Fix bugs in the autoconf misaligned accesses code fragment.

 814
 815 - Print new icmp unreachable codes as suggested by Martin Fredriksson
 816   (martin@msp.se). Also print code value when unknown for icmp redirect
 817   and time exceeded.
 818
 819 - Fix an alignment endian bug in getname(). Thanks to John Hawkinson.
 820
 821 - Define "new" domain record types if not found in arpa/nameserv.h.
 822   Resulted from a suggestion from John Hawkinson (jhawk@mit.edu). Also
 823   fixed an endian bug when printing mx record and added some new record
 824   types.
 825
 826 - Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
 827
 828 - Added T/TCP options printing. As suggested by Richard Stevens
 829   (rstevens@noao.edu)
 830
 831 - Use autoconf to detect architectures that can't handle misaligned
 832   accesses.
 833
 834 v3.1 Thu Jun 13 20:59:32 PDT 1996
 835
 836 - Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
 837   and bind (as suggested by Charles Hannum).
 838
 839 - Port to GNU autoconf.
 840
 841 - Add support for printing DVMRP and PIM traffic thanks to
 842   Havard Eidnes (Havard.Eidnes@runit.sintef.no).
 843

 855
 856 - Document -dd and -ddd. Resulted from a bug report from Charlie Slater
 857   (cslater@imatek.com).
 858
 859 - Check return status from malloc/calloc/etc.
 860
 861 - Check return status from pcap_loop() so we can print an error and
 862   exit with a bad status if there were problems.
 863
 864 - Bail if ip option length is <= 0. Resulted from a bug report from
 865   Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).
 866
 867 - Print out a little more information for sun rpc packets.
 868
 869 - Add suport for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu).
 870
 871 - Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were

 873
 874 - Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
 875   (crawdad@fnal.gov).
 876
 877 - Fix ntp_print() to not print garbage when the stratum is
 878   "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).

 887   octet for the sa_family member. Thanks to Yoshitaka Tokugawa
 888   (toku@dit.co.jp)
 889
 890 - Don't checksum ip header if we don't have all of it. Thanks to John
 891   Hawkinson (jhawk@mit.edu).
 892
 893 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
 894   Honig (jhc@bsdi.com)
 895
 896
 897 v3.1a1 Wed May  3 19:21:11 PDT 1995
 898
 899 - Include time.h when SVR4 is defined to avoid problems under Solaris
 900   2.3.
 901
 902 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
 903   strings, not the local buffer. Thanks to Stefan Petri
 904   (petri@ibr.cs.tu-bs.de).
 905
 906 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
 907   that the selected value was not used. Thanks to Pascal Hennequin
 908   (Pascal.Hennequin@hugo.int-evry.fr).
 909
 910 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
 911
 912 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
 913
 914 v3.0.3 Sun Oct  1 18:35:00 GMT 1995
 915
 916 - Although there never was a 3.0.3 release, the linux boys cleverly
 917   "released" one in late 1995.
 918
 919 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
 920
 921 - Change configuration to not use gcc v2 flags with gcc v1.
 922
 923 - Redo gmt2local() so that it works under BSDI (which seems to return
 924   an empty timezone struct from gettimeofday()). Based on report from
 925   Terry Kennedy (terry@spcvxa.spc.edu).
 926
 927 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
 928   on report from Mark Andrews (mandrews@alias.com).
 929
 930 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
 931   Orth (ro@techfak.uni-bielefeld.de).
 932
 933 - Fixed printout of connection id for uncompressed tcp slip packets.
 934   Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
 935
 936 - Hack around deficiency in Ultrix's make.
 937
 938 - Add ETHERTYPE_TRAIL define which is missing from irix5.
 939
 940 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
 941
 942 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
 943
 944 v3.0 Mon Jun 20 19:23:27 PDT 1994
 945
 946 - Added support for printing tcp option timestamps thanks to
 947   Mark Andrews (mandrews@alias.com).
 948
 949 - Reorganize protocol dumpers to take const pointers to packets so they
 950   never change the contents (i.e., they used to do endian conversions
 951   in place).  Previously, whenever more than one pass was taken over
 952   the packet, the packet contents would be dumped incorrectly (i.e.,
 953   the output form -x would be wrong on little endian machines because
 954   the protocol dumpers would modify the data).  Thanks to Charles Hannum
 955   (mycroft@gnu.ai.mit.edu) for reporting this problem.
 956
 957 - Added support for decnet protocol dumping thanks to Jeff Mogul
 958   (mogul@pa.dec.com).
 959
 960 - Fix bug that caused length of packet to be incorrectly printed
 961   (off by ether header size) for unknown ethernet types thanks
 962   to Greg Miller (gmiller@kayak.mitre.org).
 963
 964 - Added support for IPX protocol dumping thanks to Brad Parker
 965   (brad@fcr.com).
 966
 967 - Added check to verify IP header checksum under -v thanks to
 968   Brad Parker (brad@fcr.com).
 969
 970 - Move packet capture code to new libpcap library (which is
 971   packaged separately).
 972
 973 - Prototype everything and assume an ansi compiler.
 974
 975 - print-arp.c: Print hardware ethernet addresses if they're not
 976   what we expect.
 977
 978 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
 979   Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
 980
 981 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
 982   (mogul@pa.dec.com).
 983
 984 - print-icmp.c: Byte swap netmask before printing. Thanks to
 985   Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
 986
 987 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
 988   By default, only the inner packet is dumped, appended with the token
 989   "(encap)".  Under -v, both the inner and output packets are dumped
 990   (on the same line).  Note that the filter applies to the original packet,
 991   not the encapsulated packet.  So if you run tcpdump on a net with an
 992   IP Multicast tunnel, you cannot filter out the datagrams using the
 993   conventional syntax.  (You can filter away all the ip-in-ip traffic
 994   with "not ip proto 4".)
 995
 996 - print-nfs.c: Keep pending rpc's in circular table. Add generic
 997   nfs header and remove os dependences. Thanks to Jeffrey Mogul.
 998
 999 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1000
1001 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1002   (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1003   Add && and || operators
1004
1005 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1006
1007 - Fix bug with -c flag.
1008
1009 v2.2 Fri May 22 17:19:41 PDT 1992
1010
1011 - savefile.c: Remove hack that shouldn't have been exported. Add
1012   truncate checks.
1013
1014 - Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
1015   matches non-echo/reply ICMP packets.
1016
1017 - Many improvements to filter code optimizer.
1018
1019 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1020   so that protocol qualifications are allowed. For example, "ip broadcast"
1021   and "ether multicast" are valid filters.
1022
1023 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1024   Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1025   patches to netinet/if_loop.c.
1026
1027 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1028   Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1029
1030 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1031
1032 v2.1 Tue Jan 28 11:00:14 PST 1992
1033
1034 - Internal release (never publically exported).
1035
1036 v2.0.1 Sun Jan 26 21:10:10 PDT
1037
1038 - Various byte ordering fixes.
1039
1040 - Add truncation checks.
1041
1042 - inet.c: Support BSD style SIOCGIFCONF.
1043
1044 - nametoaddr.c: Handle multi addresses for single host.
1045
1046 - optimize.c: Rewritten.
1047
1048 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1049   for broadcast nets.
1050
1051 - print-atal.c: Fix an alignment bug (thanks to
1052   stanonik@nprdc.navy.mil) Add missing printf() argument.
1053
1054 - print-bootp.c: First attempt at decoding the vendor buffer.
1055
1056 - print-domain.c: Fix truncation checks.
1057
1058 - print-icmp.c: Calculate length of packets from the ip header.
1059
1060 - print-ip.c: Print frag id in decimal (so it's easier to match up
1061   with non-frags). Add support for ospf, egp and igmp.
1062
1063 - print-nfs.c: Lots of changes.
1064
1065 - print-ntp.c: Make some verbose output depend on -v.
1066
1067 - print-snmp.c: New version from John LoVerso.
1068
1069 - print-tcp.c: Print rfc1072 tcp options.
1070
1071 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1072   (microseconds) worth of precision. Fix uid bugs.
1073
1074 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1075   With this option, you can create an architecture independent binary
1076   trace file in real time, without the overhead of the packet printer.
1077   At a later time, the packets can be filtered (again) and printed.
1078
1079 - BSD is supported.  You must have BPF in your kernel.
1080   Since the filtering is now done in the kernel, fewer packets are
1081   dropped.  In fact, with BPF and the packet dumper option, a measly
1082   Sun 3/50 can keep up with a busy network.
1083
1084 - Compressed SLIP packets can now be dumped, provided you use our
1085   SLIP software and BPF.  These packets are dumped as any other IP
1086   packet; the compressed headers are dumped with the '-e' option.
1087
1088 - Machines with little-endian byte ordering are supported (thanks to
1089   Jeff Mogul).
1090
1091 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1092
1093 - IBM RT and Stanford Enetfilter support has been added by
1094   Rayan Zachariassen <rayan@canet.ca>.  Tcpdump has been tested under
1095   both the vanilla Enetfilter interface, and the extended interface
1096   (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1097
1098 - TFTP packets are now printed (requests only).
1099
1100 - BOOTP packets are now printed.
1101
1102 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1103
1104 - Sparc architectures, including the Sparcstation-1, are now
1105   supported thanks to Steve McCanne and Craig Leres.
1106
1107 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1108   University (micky@cunixc.cc.columbia.edu).
1109
1110 - IP options are now printed.
1111
1112 - RIP packets are now printed.
1113
1114 - There's a -v flag that prints out more information than the
1115   default (e.g., it will enable printing of IP ttl, tos and id)
1116   and -q flag that prints out less (e.g., it will disable
1117   interpretation of AppleTalk-in-UDP).
1118
1119 - The grammar has undergone substantial changes (if you have an
1120   earlier version of tcpdump, you should re-read the manual
1121   entry).
1122
1123   The most useful change is the addition of an expression
1124   syntax that lets you filter on arbitrary fields or values in the
1125   packet.  E.g., "ip[0] > 0x45" would print only packets with IP
1126   options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1127   packets.
1128
1129   The most painful change is that concatenation no longer means
1130   "and" -- e.g., you have to say "host foo and port bar" instead
1131   of "host foo port bar".  The up side to this down is that
1132   repeated qualifiers can be omitted, making most filter
1133   expressions shorter.  E.g., you can now say "ip host foo and
1134   (bar or baz)" to look at ip traffic between hosts foo and bar or
1135   between hosts foo and baz.  [The old way of saying this was "ip
1136   host foo and (ip host bar or ip host baz)".]
1137
1138 v2.0 Sun Jan 13 12:20:40 PST 1991
1139
1140 - Initial public release.
