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

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

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

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

671 - Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
672 Thanks to John Hawkinson.
674 - Added some more packet truncation checks.
676 - On systems that have it, use sigset() instead of signal() since
677 signal() has different semantics on these systems.
679 - Fixed some more alignment problems on the alpha.
681 - Add code to massage unprintable characters in the domain and ipx
682 printers. Thanks to John Hawkinson.
684 - Added explicit netmask support. Thanks to Steve Nuchia
685 (steve@research.oknet.com)
687 - Add "sca" keyword (for DEC cluster services) as suggested by Terry
688 Kennedy (terry@spcvxa.spc.edu)
690 - Add "atalk" keyword as suggested by John Hawkinson.
692 - Added an igrp printer. Thanks to Francis Dupont
693 (francis.dupont@inria.fr)
695 - Print IPX net numbers in hex a la Novell Netware. Thanks to Terry
696 Kennedy (terry@spcvxa.spc.edu)
698 - Fixed snmp extended tag field parsing bug. Thanks to Pascal Hennequin
699 (pascal.hennequin@hugo.int-evry.fr)

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

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

783 "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).
785 - Rewrote tcp options printer code to check for truncation. Added
786 selective acknowledgment case.
788 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
791 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
792 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
795 - Don't checksum ip header if we don't have all of it. Thanks to John
796 Hawkinson (jhawk@mit.edu).
798 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
802 v3.1a1 Wed May 3 19:21:11 PDT 1995
804 - Include time.h when SVR4 is defined to avoid problems under Solaris
807 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
808 strings, not the local buffer. Thanks to Stefan Petri
809 (petri@ibr.cs.tu-bs.de).
811 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
812 that the selected value was not used. Thanks to Pascal Hennequin
813 (Pascal.Hennequin@hugo.int-evry.fr).
815 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
817 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
819 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
821 - Although there never was a 3.0.3 release, the linux boys cleverly
822 "released" one in late 1995.
824 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
826 - Change configuration to not use gcc v2 flags with gcc v1.
828 - Redo gmt2local() so that it works under BSDI (which seems to return
829 an empty timezone struct from gettimeofday()). Based on report from
830 Terry Kennedy (terry@spcvxa.spc.edu).
832 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
833 on report from Mark Andrews (mandrews@alias.com).
835 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
836 Orth (ro@techfak.uni-bielefeld.de).
838 - Fixed printout of connection id for uncompressed tcp slip packets.
839 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
841 - Hack around deficiency in Ultrix's make.
843 - Add ETHERTYPE_TRAIL define which is missing from irix5.
845 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
847 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
849 v3.0 Mon Jun 20 19:23:27 PDT 1994
851 - Added support for printing tcp option timestamps thanks to
852 Mark Andrews (mandrews@alias.com).
854 - Reorganize protocol dumpers to take const pointers to packets so they
855 never change the contents (i.e., they used to do endian conversions
856 in place). Previously, whenever more than one pass was taken over
857 the packet, the packet contents would be dumped incorrectly (i.e.,
858 the output form -x would be wrong on little endian machines because
859 the protocol dumpers would modify the data). Thanks to Charles Hannum
860 (mycroft@gnu.ai.mit.edu) for reporting this problem.
862 - Added support for decnet protocol dumping thanks to Jeff Mogul
865 - Fix bug that caused length of packet to be incorrectly printed
866 (off by ether header size) for unknown ethernet types thanks
867 to Greg Miller (gmiller@kayak.mitre.org).
869 - Added support for IPX protocol dumping thanks to Brad Parker
872 - Added check to verify IP header checksum under -v thanks to
873 Brad Parker (brad@fcr.com).
875 - Move packet capture code to new libpcap library (which is
876 packaged separately).
878 - Prototype everything and assume an ansi compiler.
880 - print-arp.c: Print hardware ethernet addresses if they're not
883 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
884 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
886 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
889 - print-icmp.c: Byte swap netmask before printing. Thanks to
890 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
892 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
893 By default, only the inner packet is dumped, appended with the token
894 "(encap)". Under -v, both the inner and output packets are dumped
895 (on the same line). Note that the filter applies to the original packet,
896 not the encapsulated packet. So if you run tcpdump on a net with an
897 IP Multicast tunnel, you cannot filter out the datagrams using the
898 conventional syntax. (You can filter away all the ip-in-ip traffic
899 with "not ip proto 4".)
901 - print-nfs.c: Keep pending rpc's in circular table. Add generic
902 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
904 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
906 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
907 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
908 Add && and || operators
910 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
912 - Fix bug with -c flag.
914 v2.2 Fri May 22 17:19:41 PDT 1992
916 - savefile.c: Remove hack that shouldn't have been exported. Add
919 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
920 matches non-echo/reply ICMP packets.
922 - Many improvements to filter code optimizer.
924 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
925 so that protocol qualifications are allowed. For example, "ip broadcast"
926 and "ether multicast" are valid filters.
928 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
929 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
930 patches to netinet/if_loop.c.
932 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
933 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
935 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
937 v2.1 Tue Jan 28 11:00:14 PST 1992
939 - Internal release (never publically exported).
941 v2.0.1 Sun Jan 26 21:10:10 PDT
943 - Various byte ordering fixes.
945 - Add truncation checks.
947 - inet.c: Support BSD style SIOCGIFCONF.
949 - nametoaddr.c: Handle multi addresses for single host.
951 - optimize.c: Rewritten.
953 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
956 - print-atal.c: Fix an alignment bug (thanks to
957 stanonik@nprdc.navy.mil) Add missing printf() argument.
959 - print-bootp.c: First attempt at decoding the vendor buffer.
961 - print-domain.c: Fix truncation checks.
963 - print-icmp.c: Calculate length of packets from the ip header.
965 - print-ip.c: Print frag id in decimal (so it's easier to match up
966 with non-frags). Add support for ospf, egp and igmp.
968 - print-nfs.c: Lots of changes.
970 - print-ntp.c: Make some verbose output depend on -v.
972 - print-snmp.c: New version from John LoVerso.
974 - print-tcp.c: Print rfc1072 tcp options.
976 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
977 (microseconds) worth of precision. Fix uid bugs.
979 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
980 With this option, you can create an architecture independent binary
981 trace file in real time, without the overhead of the packet printer.
982 At a later time, the packets can be filtered (again) and printed.
984 - BSD is supported. You must have BPF in your kernel.
985 Since the filtering is now done in the kernel, fewer packets are
986 dropped. In fact, with BPF and the packet dumper option, a measly
987 Sun 3/50 can keep up with a busy network.
989 - Compressed SLIP packets can now be dumped, provided you use our
990 SLIP software and BPF. These packets are dumped as any other IP
991 packet; the compressed headers are dumped with the '-e' option.
993 - Machines with little-endian byte ordering are supported (thanks to
996 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
998 - IBM RT and Stanford Enetfilter support has been added by
999 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1000 both the vanilla Enetfilter interface, and the extended interface
1001 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1003 - TFTP packets are now printed (requests only).
1005 - BOOTP packets are now printed.
1007 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1009 - Sparc architectures, including the Sparcstation-1, are now
1010 supported thanks to Steve McCanne and Craig Leres.
1012 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1013 University (micky@cunixc.cc.columbia.edu).
1015 - IP options are now printed.
1017 - RIP packets are now printed.
1019 - There's a -v flag that prints out more information than the
1020 default (e.g., it will enable printing of IP ttl, tos and id)
1021 and -q flag that prints out less (e.g., it will disable
1022 interpretation of AppleTalk-in-UDP).
1024 - The grammar has undergone substantial changes (if you have an
1025 earlier version of tcpdump, you should re-read the manual
1028 The most useful change is the addition of an expression
1029 syntax that lets you filter on arbitrary fields or values in the
1030 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1031 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1034 The most painful change is that concatenation no longer means
1035 "and" -- e.g., you have to say "host foo and port bar" instead
1036 of "host foo port bar". The up side to this down is that
1037 repeated qualifiers can be omitted, making most filter
1038 expressions shorter. E.g., you can now say "ip host foo and
1039 (bar or baz)" to look at ip traffic between hosts foo and bar or
1040 between hosts foo and baz. [The old way of saying this was "ip
1041 host foo and (ip host bar or ip host baz)".]
1043 v2.0 Sun Jan 13 12:20:40 PST 1991
1045 - Initial public release.
