595 (cslater@imatek.com).
597 - Check return status from malloc/calloc/etc.
599 - Check return status from pcap_loop() so we can print an error and
600 exit with a bad status if there were problems.

612 - Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
615 - Fix ntp_print() to not print garbage when the stratum is
616 "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).
618 - Rewrote tcp options printer code to check for truncation. Added
619 selective acknowledgment case.
621 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
624 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
625 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
628 - Don't checksum ip header if we don't have all of it. Thanks to John
629 Hawkinson (jhawk@mit.edu).
631 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
635 v3.1a1 Wed May 3 19:21:11 PDT 1995
637 - Include time.h when SVR4 is defined to avoid problems under Solaris
640 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
641 strings, not the local buffer. Thanks to Stefan Petri
642 (petri@ibr.cs.tu-bs.de).
644 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
645 that the selected value was not used. Thanks to Pascal Hennequin

648 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
650 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
652 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
654 - Although there never was a 3.0.3 release, the linux boys cleverly
655 "released" one in late 1995.
657 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
659 - Change configuration to not use gcc v2 flags with gcc v1.
661 - Redo gmt2local() so that it works under BSDI (which seems to return
662 an empty timezone struct from gettimeofday()). Based on report from
663 Terry Kennedy (terry@spcvxa.spc.edu).
665 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
666 on report from Mark Andrews (mandrews@alias.com).
668 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
669 Orth (ro@techfak.uni-bielefeld.de).
671 - Fixed printout of connection id for uncompressed tcp slip packets.
672 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
674 - Hack around deficiency in Ultrix's make.
676 - Add ETHERTYPE_TRAIL define which is missing from irix5.
678 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
680 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
682 v3.0 Mon Jun 20 19:23:27 PDT 1994
684 - Added support for printing tcp option timestamps thanks to
685 Mark Andrews (mandrews@alias.com).
687 - Reorganize protocol dumpers to take const pointers to packets so they
688 never change the contents (i.e., they used to do endian conversions
689 in place). Previously, whenever more than one pass was taken over
690 the packet, the packet contents would be dumped incorrectly (i.e.,
691 the output form -x would be wrong on little endian machines because
692 the protocol dumpers would modify the data). Thanks to Charles Hannum
693 (mycroft@gnu.ai.mit.edu) for reporting this problem.
695 - Added support for decnet protocol dumping thanks to Jeff Mogul
698 - Fix bug that caused length of packet to be incorrectly printed
699 (off by ether header size) for unknown ethernet types thanks
700 to Greg Miller (gmiller@kayak.mitre.org).
702 - Added support for IPX protocol dumping thanks to Brad Parker
705 - Added check to verify IP header checksum under -v thanks to
706 Brad Parker (brad@fcr.com).
708 - Move packet capture code to new libpcap library (which is
709 packaged separately).
711 - Prototype everything and assume an ansi compiler.
713 - print-arp.c: Print hardware ethernet addresses if they're not
716 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
717 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
719 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
722 - print-icmp.c: Byte swap netmask before printing. Thanks to
723 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
725 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
726 By default, only the inner packet is dumped, appended with the token
727 "(encap)". Under -v, both the inner and output packets are dumped
728 (on the same line). Note that the filter applies to the original packet,
729 not the encapsulated packet. So if you run tcpdump on a net with an
730 IP Multicast tunnel, you cannot filter out the datagrams using the
731 conventional syntax. (You can filter away all the ip-in-ip traffic
732 with "not ip proto 4".)
734 - print-nfs.c: Keep pending rpc's in circular table. Add generic
735 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
737 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
739 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
740 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
741 Add && and || operators
743 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
745 - Fix bug with -c flag.
747 v2.2 Fri May 22 17:19:41 PDT 1992
749 - savefile.c: Remove hack that shouldn't have been exported. Add
752 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
753 matches non-echo/reply ICMP packets.
755 - Many improvements to filter code optimizer.
757 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
758 so that protocol qualifications are allowed. For example, "ip broadcast"
759 and "ether multicast" are valid filters.
761 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
762 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
763 patches to netinet/if_loop.c.
765 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
766 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
768 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
770 v2.1 Tue Jan 28 11:00:14 PST 1992
772 - Internal release (never publically exported).
774 v2.0.1 Sun Jan 26 21:10:10 PDT
776 - Various byte ordering fixes.
778 - Add truncation checks.
780 - inet.c: Support BSD style SIOCGIFCONF.
782 - nametoaddr.c: Handle multi addresses for single host.
784 - optimize.c: Rewritten.
786 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
789 - print-atal.c: Fix an alignment bug (thanks to
790 stanonik@nprdc.navy.mil) Add missing printf() argument.
792 - print-bootp.c: First attempt at decoding the vendor buffer.
794 - print-domain.c: Fix truncation checks.
796 - print-icmp.c: Calculate length of packets from the ip header.
798 - print-ip.c: Print frag id in decimal (so it's easier to match up
799 with non-frags). Add support for ospf, egp and igmp.
801 - print-nfs.c: Lots of changes.
803 - print-ntp.c: Make some verbose output depend on -v.
805 - print-snmp.c: New version from John LoVerso.
807 - print-tcp.c: Print rfc1072 tcp options.
809 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
810 (microseconds) worth of precision. Fix uid bugs.
812 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
813 With this option, you can create an architecture independent binary
814 trace file in real time, without the overhead of the packet printer.
815 At a later time, the packets can be filtered (again) and printed.
817 - BSD is supported. You must have BPF in your kernel.
818 Since the filtering is now done in the kernel, fewer packets are
819 dropped. In fact, with BPF and the packet dumper option, a measly
820 Sun 3/50 can keep up with a busy network.
822 - Compressed SLIP packets can now be dumped, provided you use our
823 SLIP software and BPF. These packets are dumped as any other IP
824 packet; the compressed headers are dumped with the '-e' option.
826 - Machines with little-endian byte ordering are supported (thanks to
829 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
831 - IBM RT and Stanford Enetfilter support has been added by
832 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
833 both the vanilla Enetfilter interface, and the extended interface
834 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
836 - TFTP packets are now printed (requests only).
838 - BOOTP packets are now printed.
840 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
842 - Sparc architectures, including the Sparcstation-1, are now
843 supported thanks to Steve McCanne and Craig Leres.
845 - SunOS 4 is now supported thanks to Micky Liu of Columbia
846 University (micky@cunixc.cc.columbia.edu).
848 - IP options are now printed.
850 - RIP packets are now printed.
852 - There's a -v flag that prints out more information than the
853 default (e.g., it will enable printing of IP ttl, tos and id)
854 and -q flag that prints out less (e.g., it will disable
855 interpretation of AppleTalk-in-UDP).
857 - The grammar has undergone substantial changes (if you have an
858 earlier version of tcpdump, you should re-read the manual
861 The most useful change is the addition of an expression
862 syntax that lets you filter on arbitrary fields or values in the
863 packet. E.g., "ip[0] > 0x45" would print only packets with IP
864 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
867 The most painful change is that concatenation no longer means
868 "and" -- e.g., you have to say "host foo and port bar" instead
869 of "host foo port bar". The up side to this down is that
870 repeated qualifiers can be omitted, making most filter
871 expressions shorter. E.g., you can now say "ip host foo and
872 (bar or baz)" to look at ip traffic between hosts foo and bar or
873 between hosts foo and baz. [The old way of saying this was "ip
874 host foo and (ip host bar or ip host baz)".]
876 v2.0 Sun Jan 13 12:20:40 PST 1991
878 - Initial public release.
