595 - Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were
596 wrong on little endian machines).
598 - Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
601 - Fix ntp_print() to not print garbage when the stratum is
602 "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).
604 - Rewrote tcp options printer code to check for truncation. Added
605 selective acknowledgment case.
607 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
610 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
611 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
614 - Don't checksum ip header if we don't have all of it. Thanks to John
615 Hawkinson (jhawk@mit.edu).
617 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
621 v3.1a1 Wed May 3 19:21:11 PDT 1995
623 - Include time.h when SVR4 is defined to avoid problems under Solaris
626 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
627 strings, not the local buffer. Thanks to Stefan Petri
628 (petri@ibr.cs.tu-bs.de).
630 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
631 that the selected value was not used. Thanks to Pascal Hennequin
632 (Pascal.Hennequin@hugo.int-evry.fr).
634 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
636 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
638 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
640 - Although there never was a 3.0.3 release, the linux boys cleverly
641 "released" one in late 1995.
643 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
645 - Change configuration to not use gcc v2 flags with gcc v1.
647 - Redo gmt2local() so that it works under BSDI (which seems to return
648 an empty timezone struct from gettimeofday()). Based on report from
649 Terry Kennedy (terry@spcvxa.spc.edu).
651 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
652 on report from Mark Andrews (mandrews@alias.com).
654 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
655 Orth (ro@techfak.uni-bielefeld.de).
657 - Fixed printout of connection id for uncompressed tcp slip packets.
658 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
660 - Hack around deficiency in Ultrix's make.
662 - Add ETHERTYPE_TRAIL define which is missing from irix5.
664 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
666 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
668 v3.0 Mon Jun 20 19:23:27 PDT 1994
670 - Added support for printing tcp option timestamps thanks to
671 Mark Andrews (mandrews@alias.com).
673 - Reorganize protocol dumpers to take const pointers to packets so they
674 never change the contents (i.e., they used to do endian conversions
675 in place). Previously, whenever more than one pass was taken over
676 the packet, the packet contents would be dumped incorrectly (i.e.,
677 the output form -x would be wrong on little endian machines because
678 the protocol dumpers would modify the data). Thanks to Charles Hannum
679 (mycroft@gnu.ai.mit.edu) for reporting this problem.
681 - Added support for decnet protocol dumping thanks to Jeff Mogul
684 - Fix bug that caused length of packet to be incorrectly printed
685 (off by ether header size) for unknown ethernet types thanks
686 to Greg Miller (gmiller@kayak.mitre.org).
688 - Added support for IPX protocol dumping thanks to Brad Parker
691 - Added check to verify IP header checksum under -v thanks to
692 Brad Parker (brad@fcr.com).
694 - Move packet capture code to new libpcap library (which is
695 packaged separately).
697 - Prototype everything and assume an ansi compiler.
699 - print-arp.c: Print hardware ethernet addresses if they're not
702 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
703 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
705 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
708 - print-icmp.c: Byte swap netmask before printing. Thanks to
709 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
711 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
712 By default, only the inner packet is dumped, appended with the token
713 "(encap)". Under -v, both the inner and output packets are dumped
714 (on the same line). Note that the filter applies to the original packet,
715 not the encapsulated packet. So if you run tcpdump on a net with an
716 IP Multicast tunnel, you cannot filter out the datagrams using the
717 conventional syntax. (You can filter away all the ip-in-ip traffic
718 with "not ip proto 4".)
720 - print-nfs.c: Keep pending rpc's in circular table. Add generic
721 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
723 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
725 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
726 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
727 Add && and || operators
729 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
731 - Fix bug with -c flag.
733 v2.2 Fri May 22 17:19:41 PDT 1992
735 - savefile.c: Remove hack that shouldn't have been exported. Add
738 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
739 matches non-echo/reply ICMP packets.
741 - Many improvements to filter code optimizer.
743 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
744 so that protocol qualifications are allowed. For example, "ip broadcast"
745 and "ether multicast" are valid filters.
747 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
748 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
749 patches to netinet/if_loop.c.
751 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
752 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
754 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
756 v2.1 Tue Jan 28 11:00:14 PST 1992
758 - Internal release (never publically exported).
760 v2.0.1 Sun Jan 26 21:10:10 PDT
762 - Various byte ordering fixes.
764 - Add truncation checks.
766 - inet.c: Support BSD style SIOCGIFCONF.
768 - nametoaddr.c: Handle multi addresses for single host.
770 - optimize.c: Rewritten.
772 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
775 - print-atal.c: Fix an alignment bug (thanks to
776 stanonik@nprdc.navy.mil) Add missing printf() argument.
778 - print-bootp.c: First attempt at decoding the vendor buffer.
780 - print-domain.c: Fix truncation checks.
782 - print-icmp.c: Calculate length of packets from the ip header.
784 - print-ip.c: Print frag id in decimal (so it's easier to match up
785 with non-frags). Add support for ospf, egp and igmp.
787 - print-nfs.c: Lots of changes.
789 - print-ntp.c: Make some verbose output depend on -v.
791 - print-snmp.c: New version from John LoVerso.
793 - print-tcp.c: Print rfc1072 tcp options.
795 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
796 (microseconds) worth of precision. Fix uid bugs.
798 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
799 With this option, you can create an architecture independent binary
800 trace file in real time, without the overhead of the packet printer.
801 At a later time, the packets can be filtered (again) and printed.
803 - BSD is supported. You must have BPF in your kernel.
804 Since the filtering is now done in the kernel, fewer packets are
805 dropped. In fact, with BPF and the packet dumper option, a measly
806 Sun 3/50 can keep up with a busy network.
808 - Compressed SLIP packets can now be dumped, provided you use our
809 SLIP software and BPF. These packets are dumped as any other IP
810 packet; the compressed headers are dumped with the '-e' option.
812 - Machines with little-endian byte ordering are supported (thanks to
815 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
817 - IBM RT and Stanford Enetfilter support has been added by
818 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
819 both the vanilla Enetfilter interface, and the extended interface
820 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
822 - TFTP packets are now printed (requests only).
824 - BOOTP packets are now printed.
826 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
828 - Sparc architectures, including the Sparcstation-1, are now
829 supported thanks to Steve McCanne and Craig Leres.
831 - SunOS 4 is now supported thanks to Micky Liu of Columbia
832 University (micky@cunixc.cc.columbia.edu).
834 - IP options are now printed.
836 - RIP packets are now printed.
838 - There's a -v flag that prints out more information than the
839 default (e.g., it will enable printing of IP ttl, tos and id)
840 and -q flag that prints out less (e.g., it will disable
841 interpretation of AppleTalk-in-UDP).
843 - The grammar has undergone substantial changes (if you have an
844 earlier version of tcpdump, you should re-read the manual
847 The most useful change is the addition of an expression
848 syntax that lets you filter on arbitrary fields or values in the
849 packet. E.g., "ip[0] > 0x45" would print only packets with IP
850 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
853 The most painful change is that concatenation no longer means
854 "and" -- e.g., you have to say "host foo and port bar" instead
855 of "host foo port bar". The up side to this down is that
856 repeated qualifiers can be omitted, making most filter
857 expressions shorter. E.g., you can now say "ip host foo and
858 (bar or baz)" to look at ip traffic between hosts foo and bar or
859 between hosts foo and baz. [The old way of saying this was "ip
860 host foo and (ip host bar or ip host baz)".]
862 v2.0 Sun Jan 13 12:20:40 PST 1991
864 - Initial public release.
