 425 - Hardwire Linux slip support since it's too hard to detect.
 426
 427 - Redo configuration of "network" libraries (-lsocket and -lnsl) to
 428   deal with IRIX. Thanks to John Hawkinson (jhawk@mit.edu)

 432
 433 - Added a configure option to disable gcc.
 434

 462   autoconf version is broken (it only puts the library name in the
 463   cache variable name). Thanks to John Hawkinson.
 464
 465 - Add a local autoconf macro to check for types; the autoconf version
 466   is broken (it uses grep instead of actually compiling a code fragment).

 469   formats.
 470
 471 - Extend OSF ip header workaround to versions 1 and 2.

 518   Bill Fenner (fenner@parc.xerox.com)
 519
 520 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
 521
 522 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
 523   Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
 524
 525 - Rewrite ospf printer to improve truncation checks.
 526
 527 - Don't parse tcp options past the EOL. As noted by David Sacerdote
 528   (davids@secnet.com). Also, check tcp options to make sure they ar
 529   actually in the tcp header (in addition to the normal truncation
 530   checks). Fix the SACK code to print the N blocks (instead of the
 531   first block N times).
 532
 533 - Don't say really small UDP packets are truncated just because they
 534   aren't big enough to be a RPC. As noted by David Sacerdote.
 535

 549
 550 - Check igmp checksum if possible. Thanks to John Hawkinson.
 551
 552 - Made changes for SINIX. Thanks to Andrej Borsenkow

 554
 555 - Use autoconf's idea of the top level directory in install targets.

 562   Thanks to John Hawkinson.
 563
 564 - Added some more packet truncation checks.

 615
 616 - Define "new" domain record types if not found in arpa/nameserv.h.
 617   Resulted from a suggestion from John Hawkinson (jhawk@mit.edu). Also
 618   fixed an endian bug when printing mx record and added some new record
 619   types.
 620
 621 - Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
 622
 623 - Added T/TCP options printing. As suggested by Richard Stevens
 624   (rstevens@noao.edu)
 625
 626 - Use autoconf to detect architectures that can't handle misaligned
 627   accesses.
 628
 629 v3.1 Thu Jun 13 20:59:32 PDT 1996
 630
 631 - Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
 632   and bind (as suggested by Charles Hannum).
 633
 634 - Port to GNU autoconf.
 635
 636 - Add support for printing DVMRP and PIM traffic thanks to
 637   Havard Eidnes (Havard.Eidnes@runit.sintef.no).

 650
 651 - Document -dd and -ddd. Resulted from a bug report from Charlie Slater
 652   (cslater@imatek.com).
 653
 654 - Check return status from malloc/calloc/etc.
 655
 656 - Check return status from pcap_loop() so we can print an error and
 657   exit with a bad status if there were problems.
 658
 659 - Bail if ip option length is <= 0. Resulted from a bug report from
 660   Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).
 661
 662 - Print out a little more information for sun rpc packets.
 663
 664 - Add suport for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu).
 665
 666 - Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were
 667   wrong on little endian machines).
 668
 669 - Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
 670   (crawdad@fnal.gov).
 671

 693
 694 - Include time.h when SVR4 is defined to avoid problems under Solaris
 695   2.3.
 696
 697 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
 698   strings, not the local buffer. Thanks to Stefan Petri
 699   (petri@ibr.cs.tu-bs.de).
 700
 701 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
 702   that the selected value was not used. Thanks to Pascal Hennequin
 703   (Pascal.Hennequin@hugo.int-evry.fr).
 704
 705 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
 706

 712   "released" one in late 1995.
 713
 714 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
 715
 716 - Change configuration to not use gcc v2 flags with gcc v1.
 717
 718 - Redo gmt2local() so that it works under BSDI (which seems to return
 719   an empty timezone struct from gettimeofday()). Based on report from
 720   Terry Kennedy (terry@spcvxa.spc.edu).
 721
 722 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
 723   on report from Mark Andrews (mandrews@alias.com).
 724
 725 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
 726   Orth (ro@techfak.uni-bielefeld.de).
 727
 728 - Fixed printout of connection id for uncompressed tcp slip packets.
 729   Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
 730
 731 - Hack around deficiency in Ultrix's make.
 732
 733 - Add ETHERTYPE_TRAIL define which is missing from irix5.
 734

 736
 737 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
 738
 739 v3.0 Mon Jun 20 19:23:27 PDT 1994
 740
 741 - Added support for printing tcp option timestamps thanks to
 742   Mark Andrews (mandrews@alias.com).
 743
 744 - Reorganize protocol dumpers to take const pointers to packets so they
 745   never change the contents (i.e., they used to do endian conversions
 746   in place).  Previously, whenever more than one pass was taken over
 747   the packet, the packet contents would be dumped incorrectly (i.e.,
 748   the output form -x would be wrong on little endian machines because
 749   the protocol dumpers would modify the data).  Thanks to Charles Hannum
 750   (mycroft@gnu.ai.mit.edu) for reporting this problem.
 751
 752 - Added support for decnet protocol dumping thanks to Jeff Mogul
 753   (mogul@pa.dec.com).
 754
 755 - Fix bug that caused length of packet to be incorrectly printed
 756   (off by ether header size) for unknown ethernet types thanks
 757   to Greg Miller (gmiller@kayak.mitre.org).
 758
 759 - Added support for IPX protocol dumping thanks to Brad Parker
 760   (brad@fcr.com).
 761
 762 - Added check to verify IP header checksum under -v thanks to
 763   Brad Parker (brad@fcr.com).
 764
 765 - Move packet capture code to new libpcap library (which is
 766   packaged separately).
 767
 768 - Prototype everything and assume an ansi compiler.
 769
 770 - print-arp.c: Print hardware ethernet addresses if they're not
 771   what we expect.
 772
 773 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
 774   Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
 775
 776 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
 777   (mogul@pa.dec.com).
 778
 779 - print-icmp.c: Byte swap netmask before printing. Thanks to
 780   Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
 781
 782 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
 783   By default, only the inner packet is dumped, appended with the token
 784   "(encap)".  Under -v, both the inner and output packets are dumped
 785   (on the same line).  Note that the filter applies to the original packet,
 786   not the encapsulated packet.  So if you run tcpdump on a net with an
 787   IP Multicast tunnel, you cannot filter out the datagrams using the
 788   conventional syntax.  (You can filter away all the ip-in-ip traffic
 789   with "not ip proto 4".)
 790
 791 - print-nfs.c: Keep pending rpc's in circular table. Add generic
 792   nfs header and remove os dependences. Thanks to Jeffrey Mogul.
 793
 794 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
 795
 796 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
 797   (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
 798   Add && and || operators
 799

 802 - Fix bug with -c flag.
 803
 804 v2.2 Fri May 22 17:19:41 PDT 1992
 805
 806 - savefile.c: Remove hack that shouldn't have been exported. Add
 807   truncate checks.
 808
 809 - Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
 810   matches non-echo/reply ICMP packets.
 811
 812 - Many improvements to filter code optimizer.
 813
 814 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
 815   so that protocol qualifications are allowed. For example, "ip broadcast"
 816   and "ether multicast" are valid filters.
 817
 818 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
 819   Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
 820   patches to netinet/if_loop.c.
 821
 822 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
 823   Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
 824
 825 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
 826
 827 v2.1 Tue Jan 28 11:00:14 PST 1992
 828
 829 - Internal release (never publically exported).
 830
 831 v2.0.1 Sun Jan 26 21:10:10 PDT
 832
 833 - Various byte ordering fixes.
 834
 835 - Add truncation checks.
 836
 837 - inet.c: Support BSD style SIOCGIFCONF.
 838
 839 - nametoaddr.c: Handle multi addresses for single host.
 840
 841 - optimize.c: Rewritten.
 842
 843 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
 844   for broadcast nets.
 845
 846 - print-atal.c: Fix an alignment bug (thanks to
 847   stanonik@nprdc.navy.mil) Add missing printf() argument.
 848
 849 - print-bootp.c: First attempt at decoding the vendor buffer.
 850
 851 - print-domain.c: Fix truncation checks.
 852
 853 - print-icmp.c: Calculate length of packets from the ip header.
 854
 855 - print-ip.c: Print frag id in decimal (so it's easier to match up
 856   with non-frags). Add support for ospf, egp and igmp.
 857
 858 - print-nfs.c: Lots of changes.
 859
 860 - print-ntp.c: Make some verbose output depend on -v.
 861
 862 - print-snmp.c: New version from John LoVerso.
 863
 864 - print-tcp.c: Print rfc1072 tcp options.
 865
 866 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
 867   (microseconds) worth of precision. Fix uid bugs.
 868
 869 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
 870   With this option, you can create an architecture independent binary
 871   trace file in real time, without the overhead of the packet printer.
 872   At a later time, the packets can be filtered (again) and printed.
 873
 874 - BSD is supported.  You must have BPF in your kernel.
 875   Since the filtering is now done in the kernel, fewer packets are
 876   dropped.  In fact, with BPF and the packet dumper option, a measly
 877   Sun 3/50 can keep up with a busy network.
 878
 879 - Compressed SLIP packets can now be dumped, provided you use our
 880   SLIP software and BPF.  These packets are dumped as any other IP
 881   packet; the compressed headers are dumped with the '-e' option.
 882
 883 - Machines with little-endian byte ordering are supported (thanks to
 884   Jeff Mogul).
 885
 886 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
 887
 888 - IBM RT and Stanford Enetfilter support has been added by
 889   Rayan Zachariassen <rayan@canet.ca>.  Tcpdump has been tested under
 890   both the vanilla Enetfilter interface, and the extended interface
 891   (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
 892
 893 - TFTP packets are now printed (requests only).
 894
 895 - BOOTP packets are now printed.
 896
 897 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
 898
 899 - Sparc architectures, including the Sparcstation-1, are now
 900   supported thanks to Steve McCanne and Craig Leres.
 901
 902 - SunOS 4 is now supported thanks to Micky Liu of Columbia
 903   University (micky@cunixc.cc.columbia.edu).
 904
 905 - IP options are now printed.
 906
 907 - RIP packets are now printed.
 908
 909 - There's a -v flag that prints out more information than the
 910   default (e.g., it will enable printing of IP ttl, tos and id)
 911   and -q flag that prints out less (e.g., it will disable
 912   interpretation of AppleTalk-in-UDP).
 913
 914 - The grammar has undergone substantial changes (if you have an
 915   earlier version of tcpdump, you should re-read the manual
 916   entry).
 917
 918   The most useful change is the addition of an expression
 919   syntax that lets you filter on arbitrary fields or values in the
 920   packet.  E.g., "ip[0] > 0x45" would print only packets with IP
 921   options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
 922   packets.
 923
 924   The most painful change is that concatenation no longer means
 925   "and" -- e.g., you have to say "host foo and port bar" instead
 926   of "host foo port bar".  The up side to this down is that
 927   repeated qualifiers can be omitted, making most filter
 928   expressions shorter.  E.g., you can now say "ip host foo and
 929   (bar or baz)" to look at ip traffic between hosts foo and bar or
 930   between hosts foo and baz.  [The old way of saying this was "ip
 931   host foo and (ip host bar or ip host baz)".]
