580  formats.
581
582- Extend OSF ip header workaround to versions 1 and 2.

589
590- AIX needs special loader options. Thanks to Jonathan I. Kamens
591  (jik@cam.ov.com)

630
631- Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
632
633- Fix dvmrp printer truncation checks and add a dvmrp probe printer.
634  Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
635
636- Rewrite ospf printer to improve truncation checks.
637
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).
643
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.
646
647v3.2.1 Sun Jul 14 03:02:26 PDT 1996

673  Thanks to John Hawkinson.
674
675- Added some more packet truncation checks.
676

730  types.
731
732- Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
733
734- Added T/TCP options printing. As suggested by Richard Stevens
735  (rstevens@noao.edu)
736
737- Use autoconf to detect architectures that can't handle misaligned
738  accesses.
739
740v3.1 Thu Jun 13 20:59:32 PDT 1996
741
742- Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
743  and bind (as suggested by Charles Hannum).
744
745- Port to GNU autoconf.
746
747- Add support for printing DVMRP and PIM traffic thanks to
748  Havard Eidnes (Havard.Eidnes@runit.sintef.no).

763  (cslater@imatek.com).
764
765- Check return status from malloc/calloc/etc.
766
767- Check return status from pcap_loop() so we can print an error and
768  exit with a bad status if there were problems.
769
770- Bail if ip option length is <= 0. Resulted from a bug report from
771  Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).
772
773- Print out a little more information for sun rpc packets.
774
775- Add suport for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu).

804
805- Include time.h when SVR4 is defined to avoid problems under Solaris
806  2.3.
807
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).
811
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).
815
816- Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
817
818- BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
819
820v3.0.3 Sun Oct  1 18:35:00 GMT 1995
821
822- Although there never was a 3.0.3 release, the linux boys cleverly
823  "released" one in late 1995.
824
825v3.0.2 Thu Apr 20 21:28:16 PDT 1995
826
827- Change configuration to not use gcc v2 flags with gcc v1.
828
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).
832
833- Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
834  on report from Mark Andrews (mandrews@alias.com).
835
836- Don't pass cc flags to gcc. Resulted from a bug report from Rainer
837  Orth (ro@techfak.uni-bielefeld.de).
838
839- Fixed printout of connection id for uncompressed tcp slip packets.
840  Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
841
842- Hack around deficiency in Ultrix's make.
843
844- Add ETHERTYPE_TRAIL define which is missing from irix5.
845
846v3.0.1 Wed Aug 31 22:42:26 PDT 1994
847
848- Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
849
850v3.0 Mon Jun 20 19:23:27 PDT 1994
851
852- Added support for printing tcp option timestamps thanks to
853  Mark Andrews (mandrews@alias.com).
854
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.
862
863- Added support for decnet protocol dumping thanks to Jeff Mogul
864  (mogul@pa.dec.com).
865
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).
869
870- Added support for IPX protocol dumping thanks to Brad Parker
871  (brad@fcr.com).
872
873- Added check to verify IP header checksum under -v thanks to
874  Brad Parker (brad@fcr.com).
875
876- Move packet capture code to new libpcap library (which is
877  packaged separately).
878
879- Prototype everything and assume an ansi compiler.
880
881- print-arp.c: Print hardware ethernet addresses if they're not
882  what we expect.
883
884- print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
885  Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
886
887- print-fddi.c: Improvements. Thanks to Jeffrey Mogul
888  (mogul@pa.dec.com).
889
890- print-icmp.c: Byte swap netmask before printing. Thanks to
891  Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
892
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".)
901
902- print-nfs.c: Keep pending rpc's in circular table. Add generic
903  nfs header and remove os dependences. Thanks to Jeffrey Mogul.
904
905- print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
906
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
910
911v2.2.1 Tue Jun 6 17:57:22 PDT 1992
912
913- Fix bug with -c flag.
914
915v2.2 Fri May 22 17:19:41 PDT 1992
916
917- savefile.c: Remove hack that shouldn't have been exported. Add
918  truncate checks.
919
920- Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
921  matches non-echo/reply ICMP packets.
922
923- Many improvements to filter code optimizer.
924
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.
928
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.
932
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.
935
936- Added EGP and OSPF printers, thanks to Jeffrey Honig.

943
944- Various byte ordering fixes.
945
946- Add truncation checks.
947
948- inet.c: Support BSD style SIOCGIFCONF.
949
950- nametoaddr.c: Handle multi addresses for single host.
951
952- optimize.c: Rewritten.
953
954- pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
955  for broadcast nets.
956
957- print-atal.c: Fix an alignment bug (thanks to
958  stanonik@nprdc.navy.mil) Add missing printf() argument.
959
960- print-bootp.c: First attempt at decoding the vendor buffer.
961
962- print-domain.c: Fix truncation checks.
963
964- print-icmp.c: Calculate length of packets from the ip header.
965
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.
968
969- print-nfs.c: Lots of changes.
970
971- print-ntp.c: Make some verbose output depend on -v.
972
973- print-snmp.c: New version from John LoVerso.
974
975- print-tcp.c: Print rfc1072 tcp options.
976
977- tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
978  (microseconds) worth of precision. Fix uid bugs.
979
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.
984
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.
989
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.
993
994- Machines with little-endian byte ordering are supported (thanks to
995  Jeff Mogul).
996
997- Ultrix 4.0 is supported (also thanks to Jeff Mogul).
998
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.
1003
1004- TFTP packets are now printed (requests only).
1005
1006- BOOTP packets are now printed.
1007
1008- SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1009
1010- Sparc architectures, including the Sparcstation-1, are now
1011  supported thanks to Steve McCanne and Craig Leres.
1012
1013- SunOS 4 is now supported thanks to Micky Liu of Columbia
1014  University (micky@cunixc.cc.columbia.edu).
1015
1016- IP options are now printed.
1017
1018- RIP packets are now printed.
1019
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).
1024
1025- The grammar has undergone substantial changes (if you have an
1026  earlier version of tcpdump, you should re-read the manual
1027  entry).
1028
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
1033  packets.
1034
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)".]
