543 Marty Leisner (leisner@sdsp.mc.xerox.com)
545 - Add a local autoconf macro to check for routines in libraries; the
546 autoconf version is broken (it only puts the library name in the
547 cache variable name). Thanks to John Hawkinson.
549 - Add a local autoconf macro to check for types; the autoconf version
550 is broken (it uses grep instead of actually compiling a code fragment).
552 - Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
555 - Extend OSF ip header workaround to versions 1 and 2.
557 - Fix some signed problems in the nfs printer. As reported by David
558 Sacerdote (davids@silence.secnet.com)
560 - Detect group wheel and use it as the default since BSD/OS' install
561 can't hack numeric groups. Reported by David Sacerdote.
563 - AIX needs special loader options. Thanks to Jonathan I. Kamens
566 - Fixed the nfs printer to print port numbers in decimal. Thanks to
567 Kent Vander Velden (graphix@iastate.edu)

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

597 - Avoid solaris compiler warnings. Thanks to Bruce Barnett
598 (barnett@grymoire.crd.ge.com)
600 - Fix rip printer to not print one more route than is actually in the
601 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
602 Bill Fenner (fenner@parc.xerox.com)
604 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
606 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
607 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
609 - Rewrite ospf printer to improve truncation checks.
611 - Don't parse tcp options past the EOL. As noted by David Sacerdote
612 (davids@secnet.com). Also, check tcp options to make sure they ar
613 actually in the tcp header (in addition to the normal truncation
614 checks). Fix the SACK code to print the N blocks (instead of the
615 first block N times).
617 - Don't say really small UDP packets are truncated just because they
618 aren't big enough to be a RPC. As noted by David Sacerdote.
620 v3.2.1 Sun Jul 14 03:02:26 PDT 1996

646 Thanks to John Hawkinson.
648 - Added some more packet truncation checks.
650 - On systems that have it, use sigset() instead of signal() since
651 signal() has different semantics on these systems.
653 - Fixed some more alignment problems on the alpha.
655 - Add code to massage unprintable characters in the domain and ipx
656 printers. Thanks to John Hawkinson.
658 - Added explicit netmask support. Thanks to Steve Nuchia
659 (steve@research.oknet.com)
661 - Add "sca" keyword (for DEC cluster services) as suggested by Terry
662 Kennedy (terry@spcvxa.spc.edu)
664 - Add "atalk" keyword as suggested by John Hawkinson.
666 - Added an igrp printer. Thanks to Francis Dupont
667 (francis.dupont@inria.fr)
669 - Print IPX net numbers in hex a la Novell Netware. Thanks to Terry

718 - Port to GNU autoconf.
720 - Add support for printing DVMRP and PIM traffic thanks to
721 Havard Eidnes (Havard.Eidnes@runit.sintef.no).

740 - Check return status from pcap_loop() so we can print an error and
741 exit with a bad status if there were problems.
743 - Bail if ip option length is <= 0. Resulted from a bug report from
744 Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).

757 "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).
759 - Rewrote tcp options printer code to check for truncation. Added
760 selective acknowledgment case.
762 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
765 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
766 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
769 - Don't checksum ip header if we don't have all of it. Thanks to John
770 Hawkinson (jhawk@mit.edu).
772 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
776 v3.1a1 Wed May 3 19:21:11 PDT 1995
778 - Include time.h when SVR4 is defined to avoid problems under Solaris
781 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
782 strings, not the local buffer. Thanks to Stefan Petri
783 (petri@ibr.cs.tu-bs.de).
785 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
786 that the selected value was not used. Thanks to Pascal Hennequin
787 (Pascal.Hennequin@hugo.int-evry.fr).
789 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
791 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
793 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
795 - Although there never was a 3.0.3 release, the linux boys cleverly
796 "released" one in late 1995.
798 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
800 - Change configuration to not use gcc v2 flags with gcc v1.
802 - Redo gmt2local() so that it works under BSDI (which seems to return
803 an empty timezone struct from gettimeofday()). Based on report from
804 Terry Kennedy (terry@spcvxa.spc.edu).
806 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
807 on report from Mark Andrews (mandrews@alias.com).
809 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
810 Orth (ro@techfak.uni-bielefeld.de).

813 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
815 - Hack around deficiency in Ultrix's make.
817 - Add ETHERTYPE_TRAIL define which is missing from irix5.
819 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
821 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
823 v3.0 Mon Jun 20 19:23:27 PDT 1994
825 - Added support for printing tcp option timestamps thanks to
826 Mark Andrews (mandrews@alias.com).
828 - Reorganize protocol dumpers to take const pointers to packets so they
829 never change the contents (i.e., they used to do endian conversions
830 in place). Previously, whenever more than one pass was taken over
831 the packet, the packet contents would be dumped incorrectly (i.e.,
832 the output form -x would be wrong on little endian machines because
833 the protocol dumpers would modify the data). Thanks to Charles Hannum
834 (mycroft@gnu.ai.mit.edu) for reporting this problem.
836 - Added support for decnet protocol dumping thanks to Jeff Mogul
839 - Fix bug that caused length of packet to be incorrectly printed
840 (off by ether header size) for unknown ethernet types thanks
841 to Greg Miller (gmiller@kayak.mitre.org).
843 - Added support for IPX protocol dumping thanks to Brad Parker
846 - Added check to verify IP header checksum under -v thanks to
847 Brad Parker (brad@fcr.com).
849 - Move packet capture code to new libpcap library (which is
850 packaged separately).
852 - Prototype everything and assume an ansi compiler.
854 - print-arp.c: Print hardware ethernet addresses if they're not
857 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
858 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
860 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
863 - print-icmp.c: Byte swap netmask before printing. Thanks to
864 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
866 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
867 By default, only the inner packet is dumped, appended with the token
868 "(encap)". Under -v, both the inner and output packets are dumped
869 (on the same line). Note that the filter applies to the original packet,
870 not the encapsulated packet. So if you run tcpdump on a net with an
871 IP Multicast tunnel, you cannot filter out the datagrams using the
872 conventional syntax. (You can filter away all the ip-in-ip traffic
873 with "not ip proto 4".)
875 - print-nfs.c: Keep pending rpc's in circular table. Add generic
876 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
878 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
880 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
881 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
882 Add && and || operators
884 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
886 - Fix bug with -c flag.
888 v2.2 Fri May 22 17:19:41 PDT 1992
890 - savefile.c: Remove hack that shouldn't have been exported. Add
893 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
894 matches non-echo/reply ICMP packets.
896 - Many improvements to filter code optimizer.
898 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
899 so that protocol qualifications are allowed. For example, "ip broadcast"
900 and "ether multicast" are valid filters.
902 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
903 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
904 patches to netinet/if_loop.c.
906 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
907 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
909 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
911 v2.1 Tue Jan 28 11:00:14 PST 1992
913 - Internal release (never publically exported).
915 v2.0.1 Sun Jan 26 21:10:10 PDT
917 - Various byte ordering fixes.
919 - Add truncation checks.
921 - inet.c: Support BSD style SIOCGIFCONF.
923 - nametoaddr.c: Handle multi addresses for single host.
925 - optimize.c: Rewritten.
927 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
930 - print-atal.c: Fix an alignment bug (thanks to
931 stanonik@nprdc.navy.mil) Add missing printf() argument.
933 - print-bootp.c: First attempt at decoding the vendor buffer.
935 - print-domain.c: Fix truncation checks.
937 - print-icmp.c: Calculate length of packets from the ip header.
939 - print-ip.c: Print frag id in decimal (so it's easier to match up
940 with non-frags). Add support for ospf, egp and igmp.
942 - print-nfs.c: Lots of changes.
944 - print-ntp.c: Make some verbose output depend on -v.
946 - print-snmp.c: New version from John LoVerso.
948 - print-tcp.c: Print rfc1072 tcp options.
950 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
951 (microseconds) worth of precision. Fix uid bugs.
953 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
954 With this option, you can create an architecture independent binary
955 trace file in real time, without the overhead of the packet printer.
956 At a later time, the packets can be filtered (again) and printed.
958 - BSD is supported. You must have BPF in your kernel.
959 Since the filtering is now done in the kernel, fewer packets are
960 dropped. In fact, with BPF and the packet dumper option, a measly
961 Sun 3/50 can keep up with a busy network.
963 - Compressed SLIP packets can now be dumped, provided you use our
964 SLIP software and BPF. These packets are dumped as any other IP
965 packet; the compressed headers are dumped with the '-e' option.
967 - Machines with little-endian byte ordering are supported (thanks to
970 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
972 - IBM RT and Stanford Enetfilter support has been added by
973 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
974 both the vanilla Enetfilter interface, and the extended interface
975 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
977 - TFTP packets are now printed (requests only).
979 - BOOTP packets are now printed.
981 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
983 - Sparc architectures, including the Sparcstation-1, are now
984 supported thanks to Steve McCanne and Craig Leres.
986 - SunOS 4 is now supported thanks to Micky Liu of Columbia
987 University (micky@cunixc.cc.columbia.edu).
989 - IP options are now printed.
991 - RIP packets are now printed.
993 - There's a -v flag that prints out more information than the
994 default (e.g., it will enable printing of IP ttl, tos and id)
995 and -q flag that prints out less (e.g., it will disable
996 interpretation of AppleTalk-in-UDP).
998 - The grammar has undergone substantial changes (if you have an
999 earlier version of tcpdump, you should re-read the manual
1002 The most useful change is the addition of an expression
1003 syntax that lets you filter on arbitrary fields or values in the
1004 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1005 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1008 The most painful change is that concatenation no longer means
1009 "and" -- e.g., you have to say "host foo and port bar" instead
1010 of "host foo port bar". The up side to this down is that
1011 repeated qualifiers can be omitted, making most filter
1012 expressions shorter. E.g., you can now say "ip host foo and
1013 (bar or baz)" to look at ip traffic between hosts foo and bar or
1014 between hosts foo and baz. [The old way of saying this was "ip
1015 host foo and (ip host bar or ip host baz)".]
1017 v2.0 Sun Jan 13 12:20:40 PST 1991
1019 - Initial public release.
