534 v3.4 Sat Jul 25 12:40:55 PDT 1998
536 - Hardwire Linux slip support since it's too hard to detect.
538 - Redo configuration of "network" libraries (-lsocket and -lnsl) to
539 deal with IRIX. Thanks to John Hawkinson (jhawk@mit.edu)
541 - Added -a which tries to translate network and broadcast addresses to
542 names. Suggested by Rob van Nieuwkerk (robn@verdi.et.tudelft.nl)
544 - Added a configure option to disable gcc.
546 - Added a "raw" packet printer.
548 - Not having an interface address is no longer fatal. Requested by John
551 - Rework signal setup to accommodate Linux.
553 - OSPF truncation check fix. Also display the type of OSPF packets
554 using MD5 authentication. Thanks to Brian Wellington
557 - Fix truncation check bugs in the Kerberos printer. Reported by Ezra
558 Peisach (epeisach@mit.edu)
560 - Don't catch SIGHUP when invoked with nohup(1). Thanks to Dave Plonka
563 - Specify full install target as a way of detecting if install
564 directory does not exist. Thanks to Dave Plonka.
566 - Bit-swap FDDI addresses for BSD/OS too. Thanks to Paul Vixie
569 - Fix off-by-one bug when testing size of ethernet packets. Thanks to
570 Marty Leisner (leisner@sdsp.mc.xerox.com)
572 - Add a local autoconf macro to check for routines in libraries; the
573 autoconf version is broken (it only puts the library name in the
574 cache variable name). Thanks to John Hawkinson.
576 - Add a local autoconf macro to check for types; the autoconf version
577 is broken (it uses grep instead of actually compiling a code fragment).
579 - Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
582 - Extend OSF ip header workaround to versions 1 and 2.
584 - Fix some signed problems in the nfs printer. As reported by David
585 Sacerdote (davids@silence.secnet.com)
587 - Detect group wheel and use it as the default since BSD/OS' install
588 can't hack numeric groups. Reported by David Sacerdote.
590 - AIX needs special loader options. Thanks to Jonathan I. Kamens
593 - Fixed the nfs printer to print port numbers in decimal. Thanks to
594 Kent Vander Velden (graphix@iastate.edu)

598 - Disallow network masks with non-network bits set.
600 - Attempt to detect "egcs" versions of gcc.
602 - Add missing closing double quotes when displaying bootp strings.
603 Reported by Viet-Trung Luu (vluu@picard.math.uwaterloo.ca)

624 - Avoid solaris compiler warnings. Thanks to Bruce Barnett
625 (barnett@grymoire.crd.ge.com)
627 - Fix rip printer to not print one more route than is actually in the
628 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
629 Bill Fenner (fenner@parc.xerox.com)
631 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
633 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
634 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
636 - Rewrite ospf printer to improve truncation checks.
638 - Don't parse tcp options past the EOL. As noted by David Sacerdote
639 (davids@secnet.com). Also, check tcp options to make sure they ar
640 actually in the tcp header (in addition to the normal truncation
641 checks). Fix the SACK code to print the N blocks (instead of the
642 first block N times).
644 - Don't say really small UDP packets are truncated just because they
645 aren't big enough to be a RPC. As noted by David Sacerdote.
647 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
649 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
652 - Print mtu for icmp unreach need frag packets. Thanks to John
653 Hawkinson (jhawk@mit.edu)

664 (borsenkow.msk@sni.de)
666 - Use autoconf's idea of the top level directory in install targets.
667 Thanks to John Hawkinson.
669 - Avoid infinite loop in tcp options printing code. Thanks to Jeffrey

672 - Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
673 Thanks to John Hawkinson.
675 - Added some more packet truncation checks.
677 - On systems that have it, use sigset() instead of signal() since
678 signal() has different semantics on these systems.
680 - Fixed some more alignment problems on the alpha.
682 - Add code to massage unprintable characters in the domain and ipx
683 printers. Thanks to John Hawkinson.
685 - Added explicit netmask support. Thanks to Steve Nuchia
686 (steve@research.oknet.com)
688 - Add "sca" keyword (for DEC cluster services) as suggested by Terry
689 Kennedy (terry@spcvxa.spc.edu)
691 - Add "atalk" keyword as suggested by John Hawkinson.
693 - Added an igrp printer. Thanks to Francis Dupont
694 (francis.dupont@inria.fr)
696 - Print IPX net numbers in hex a la Novell Netware. Thanks to Terry
697 Kennedy (terry@spcvxa.spc.edu)

725 - Fix an alignment endian bug in getname(). Thanks to John Hawkinson.
727 - Define "new" domain record types if not found in arpa/nameserv.h.
728 Resulted from a suggestion from John Hawkinson (jhawk@mit.edu). Also
729 fixed an endian bug when printing mx record and added some new record
732 - Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
734 - Added T/TCP options printing. As suggested by Richard Stevens
737 - Use autoconf to detect architectures that can't handle misaligned
740 v3.1 Thu Jun 13 20:59:32 PDT 1996
742 - Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
743 and bind (as suggested by Charles Hannum).
745 - Port to GNU autoconf.
747 - Add support for printing DVMRP and PIM traffic thanks to
748 Havard Eidnes (Havard.Eidnes@runit.sintef.no).

762 - Document -dd and -ddd. Resulted from a bug report from Charlie Slater
763 (cslater@imatek.com).
765 - Check return status from malloc/calloc/etc.
767 - Check return status from pcap_loop() so we can print an error and
768 exit with a bad status if there were problems.
770 - Bail if ip option length is <= 0. Resulted from a bug report from
771 Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).

784 "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).
786 - Rewrote tcp options printer code to check for truncation. Added
787 selective acknowledgment case.
789 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
792 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
793 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
796 - Don't checksum ip header if we don't have all of it. Thanks to John
797 Hawkinson (jhawk@mit.edu).
799 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
803 v3.1a1 Wed May 3 19:21:11 PDT 1995
805 - Include time.h when SVR4 is defined to avoid problems under Solaris
808 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
809 strings, not the local buffer. Thanks to Stefan Petri
810 (petri@ibr.cs.tu-bs.de).
812 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
813 that the selected value was not used. Thanks to Pascal Hennequin
814 (Pascal.Hennequin@hugo.int-evry.fr).
816 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
818 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
820 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
822 - Although there never was a 3.0.3 release, the linux boys cleverly
823 "released" one in late 1995.
825 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
827 - Change configuration to not use gcc v2 flags with gcc v1.
829 - Redo gmt2local() so that it works under BSDI (which seems to return
830 an empty timezone struct from gettimeofday()). Based on report from
831 Terry Kennedy (terry@spcvxa.spc.edu).
833 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
834 on report from Mark Andrews (mandrews@alias.com).
836 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
837 Orth (ro@techfak.uni-bielefeld.de).
839 - Fixed printout of connection id for uncompressed tcp slip packets.
840 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
842 - Hack around deficiency in Ultrix's make.
844 - Add ETHERTYPE_TRAIL define which is missing from irix5.
846 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
848 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
850 v3.0 Mon Jun 20 19:23:27 PDT 1994
852 - Added support for printing tcp option timestamps thanks to
853 Mark Andrews (mandrews@alias.com).
855 - Reorganize protocol dumpers to take const pointers to packets so they
856 never change the contents (i.e., they used to do endian conversions
857 in place). Previously, whenever more than one pass was taken over
858 the packet, the packet contents would be dumped incorrectly (i.e.,
859 the output form -x would be wrong on little endian machines because
860 the protocol dumpers would modify the data). Thanks to Charles Hannum
861 (mycroft@gnu.ai.mit.edu) for reporting this problem.
863 - Added support for decnet protocol dumping thanks to Jeff Mogul
866 - Fix bug that caused length of packet to be incorrectly printed
867 (off by ether header size) for unknown ethernet types thanks
868 to Greg Miller (gmiller@kayak.mitre.org).
870 - Added support for IPX protocol dumping thanks to Brad Parker
873 - Added check to verify IP header checksum under -v thanks to
874 Brad Parker (brad@fcr.com).
876 - Move packet capture code to new libpcap library (which is
877 packaged separately).
879 - Prototype everything and assume an ansi compiler.
881 - print-arp.c: Print hardware ethernet addresses if they're not
884 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
885 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
887 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
890 - print-icmp.c: Byte swap netmask before printing. Thanks to
891 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
893 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
894 By default, only the inner packet is dumped, appended with the token
895 "(encap)". Under -v, both the inner and output packets are dumped
896 (on the same line). Note that the filter applies to the original packet,
897 not the encapsulated packet. So if you run tcpdump on a net with an
898 IP Multicast tunnel, you cannot filter out the datagrams using the
899 conventional syntax. (You can filter away all the ip-in-ip traffic
900 with "not ip proto 4".)
902 - print-nfs.c: Keep pending rpc's in circular table. Add generic
903 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
905 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
907 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
908 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
909 Add && and || operators
911 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
913 - Fix bug with -c flag.
915 v2.2 Fri May 22 17:19:41 PDT 1992
917 - savefile.c: Remove hack that shouldn't have been exported. Add
920 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
921 matches non-echo/reply ICMP packets.
923 - Many improvements to filter code optimizer.
925 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
926 so that protocol qualifications are allowed. For example, "ip broadcast"
927 and "ether multicast" are valid filters.
929 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
930 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
931 patches to netinet/if_loop.c.
933 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
934 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
936 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
938 v2.1 Tue Jan 28 11:00:14 PST 1992
940 - Internal release (never publically exported).
942 v2.0.1 Sun Jan 26 21:10:10 PDT
944 - Various byte ordering fixes.
946 - Add truncation checks.
948 - inet.c: Support BSD style SIOCGIFCONF.
950 - nametoaddr.c: Handle multi addresses for single host.
952 - optimize.c: Rewritten.
954 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
957 - print-atal.c: Fix an alignment bug (thanks to
958 stanonik@nprdc.navy.mil) Add missing printf() argument.
960 - print-bootp.c: First attempt at decoding the vendor buffer.
962 - print-domain.c: Fix truncation checks.
964 - print-icmp.c: Calculate length of packets from the ip header.
966 - print-ip.c: Print frag id in decimal (so it's easier to match up
967 with non-frags). Add support for ospf, egp and igmp.
969 - print-nfs.c: Lots of changes.
971 - print-ntp.c: Make some verbose output depend on -v.
973 - print-snmp.c: New version from John LoVerso.
975 - print-tcp.c: Print rfc1072 tcp options.
977 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
978 (microseconds) worth of precision. Fix uid bugs.
980 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
981 With this option, you can create an architecture independent binary
982 trace file in real time, without the overhead of the packet printer.
983 At a later time, the packets can be filtered (again) and printed.
985 - BSD is supported. You must have BPF in your kernel.
986 Since the filtering is now done in the kernel, fewer packets are
987 dropped. In fact, with BPF and the packet dumper option, a measly
988 Sun 3/50 can keep up with a busy network.
990 - Compressed SLIP packets can now be dumped, provided you use our
991 SLIP software and BPF. These packets are dumped as any other IP
992 packet; the compressed headers are dumped with the '-e' option.
994 - Machines with little-endian byte ordering are supported (thanks to
997 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
999 - IBM RT and Stanford Enetfilter support has been added by
1000 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1001 both the vanilla Enetfilter interface, and the extended interface
1002 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1004 - TFTP packets are now printed (requests only).
1006 - BOOTP packets are now printed.
1008 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1010 - Sparc architectures, including the Sparcstation-1, are now
1011 supported thanks to Steve McCanne and Craig Leres.
1013 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1014 University (micky@cunixc.cc.columbia.edu).
1016 - IP options are now printed.
1018 - RIP packets are now printed.
1020 - There's a -v flag that prints out more information than the
1021 default (e.g., it will enable printing of IP ttl, tos and id)
1022 and -q flag that prints out less (e.g., it will disable
1023 interpretation of AppleTalk-in-UDP).
1025 - The grammar has undergone substantial changes (if you have an
1026 earlier version of tcpdump, you should re-read the manual
1029 The most useful change is the addition of an expression
1030 syntax that lets you filter on arbitrary fields or values in the
1031 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1032 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1035 The most painful change is that concatenation no longer means
1036 "and" -- e.g., you have to say "host foo and port bar" instead
1037 of "host foo port bar". The up side to this down is that
1038 repeated qualifiers can be omitted, making most filter
1039 expressions shorter. E.g., you can now say "ip host foo and
1040 (bar or baz)" to look at ip traffic between hosts foo and bar or
1041 between hosts foo and baz. [The old way of saying this was "ip
1042 host foo and (ip host bar or ip host baz)".]
1044 v2.0 Sun Jan 13 12:20:40 PST 1991
1046 - Initial public release.
