574 - Avoid solaris compiler warnings. Thanks to Bruce Barnett
575 (barnett@grymoire.crd.ge.com)
577 - Fix rip printer to not print one more route than is actually in the
578 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
579 Bill Fenner (fenner@parc.xerox.com)
581 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.

584 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
586 - Rewrite ospf printer to improve truncation checks.
588 - Don't parse tcp options past the EOL. As noted by David Sacerdote
589 (davids@secnet.com). Also, check tcp options to make sure they ar
590 actually in the tcp header (in addition to the normal truncation
591 checks). Fix the SACK code to print the N blocks (instead of the
592 first block N times).
594 - Don't say really small UDP packets are truncated just because they
595 aren't big enough to be a RPC. As noted by David Sacerdote.

737 selective acknowledgment case.
739 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
742 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
743 octet for the sa_family member. Thanks to Yoshitaka Tokugawa

753 v3.1a1 Wed May 3 19:21:11 PDT 1995
755 - Include time.h when SVR4 is defined to avoid problems under Solaris
758 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
759 strings, not the local buffer. Thanks to Stefan Petri
760 (petri@ibr.cs.tu-bs.de).
762 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
763 that the selected value was not used. Thanks to Pascal Hennequin
764 (Pascal.Hennequin@hugo.int-evry.fr).
766 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
768 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
770 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
772 - Although there never was a 3.0.3 release, the linux boys cleverly
773 "released" one in late 1995.
775 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
777 - Change configuration to not use gcc v2 flags with gcc v1.
779 - Redo gmt2local() so that it works under BSDI (which seems to return
780 an empty timezone struct from gettimeofday()). Based on report from
781 Terry Kennedy (terry@spcvxa.spc.edu).
783 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
784 on report from Mark Andrews (mandrews@alias.com).
786 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
787 Orth (ro@techfak.uni-bielefeld.de).

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