267 (davids@secnet.com). Also, check tcp options to make sure they ar
268 actually in the tcp header (in addition to the normal truncation
269 checks). Fix the SACK code to print the N blocks (instead of the
270 first block N times).
272 - Don't say really small UDP packets are truncated just because they
273 aren't big enough to be a RPC. As noted by David Sacerdote.
275 v3.2.1 Sun Jul 14 03:02:26 PDT 1996

305 - On systems that have it, use sigset() instead of signal() since
306 signal() has different semantics on these systems.
308 - Fixed some more alignment problems on the alpha.
310 - Add code to massage unprintable characters in the domain and ipx
311 printers. Thanks to John Hawkinson.

448 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
450 - Although there never was a 3.0.3 release, the linux boys cleverly
451 "released" one in late 1995.
453 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
455 - Change configuration to not use gcc v2 flags with gcc v1.
457 - Redo gmt2local() so that it works under BSDI (which seems to return
458 an empty timezone struct from gettimeofday()). Based on report from
459 Terry Kennedy (terry@spcvxa.spc.edu).
461 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
462 on report from Mark Andrews (mandrews@alias.com).

476 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
478 v3.0 Mon Jun 20 19:23:27 PDT 1994
480 - Added support for printing tcp option timestamps thanks to
481 Mark Andrews (mandrews@alias.com).
483 - Reorganize protocol dumpers to take const pointers to packets so they
484 never change the contents (i.e., they used to do endian conversions
485 in place). Previously, whenever more than one pass was taken over
486 the packet, the packet contents would be dumped incorrectly (i.e.,
487 the output form -x would be wrong on little endian machines because
488 the protocol dumpers would modify the data). Thanks to Charles Hannum
489 (mycroft@gnu.ai.mit.edu) for reporting this problem.
491 - Added support for decnet protocol dumping thanks to Jeff Mogul
494 - Fix bug that caused length of packet to be incorrectly printed
495 (off by ether header size) for unknown ethernet types thanks
496 to Greg Miller (gmiller@kayak.mitre.org).
498 - Added support for IPX protocol dumping thanks to Brad Parker
501 - Added check to verify IP header checksum under -v thanks to
502 Brad Parker (brad@fcr.com).
504 - Move packet capture code to new libpcap library (which is
505 packaged separately).
507 - Prototype everything and assume an ansi compiler.
509 - print-arp.c: Print hardware ethernet addresses if they're not
512 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
513 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
515 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
518 - print-icmp.c: Byte swap netmask before printing. Thanks to
519 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
521 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
522 By default, only the inner packet is dumped, appended with the token
523 "(encap)". Under -v, both the inner and output packets are dumped
524 (on the same line). Note that the filter applies to the original packet,
525 not the encapsulated packet. So if you run tcpdump on a net with an
526 IP Multicast tunnel, you cannot filter out the datagrams using the
527 conventional syntax. (You can filter away all the ip-in-ip traffic
528 with "not ip proto 4".)
530 - print-nfs.c: Keep pending rpc's in circular table. Add generic
531 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
533 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
535 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
536 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
537 Add && and || operators
539 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
541 - Fix bug with -c flag.
543 v2.2 Fri May 22 17:19:41 PDT 1992
545 - savefile.c: Remove hack that shouldn't have been exported. Add
548 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
549 matches non-echo/reply ICMP packets.
551 - Many improvements to filter code optimizer.
553 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
554 so that protocol qualifications are allowed. For example, "ip broadcast"
555 and "ether multicast" are valid filters.
557 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
558 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
559 patches to netinet/if_loop.c.
561 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
562 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
564 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
566 v2.1 Tue Jan 28 11:00:14 PST 1992
568 - Internal release (never publically exported).
570 v2.0.1 Sun Jan 26 21:10:10 PDT
572 - Various byte ordering fixes.
574 - Add truncation checks.
576 - inet.c: Support BSD style SIOCGIFCONF.
578 - nametoaddr.c: Handle multi addresses for single host.
580 - optimize.c: Rewritten.
582 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
585 - print-atal.c: Fix an alignment bug (thanks to
586 stanonik@nprdc.navy.mil) Add missing printf() argument.
588 - print-bootp.c: First attempt at decoding the vendor buffer.
590 - print-domain.c: Fix truncation checks.
592 - print-icmp.c: Calculate length of packets from the ip header.
594 - print-ip.c: Print frag id in decimal (so it's easier to match up
595 with non-frags). Add support for ospf, egp and igmp.
597 - print-nfs.c: Lots of changes.
599 - print-ntp.c: Make some verbose output depend on -v.
601 - print-snmp.c: New version from John LoVerso.
603 - print-tcp.c: Print rfc1072 tcp options.
605 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
606 (microseconds) worth of precision. Fix uid bugs.
608 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
609 With this option, you can create an architecture independent binary
610 trace file in real time, without the overhead of the packet printer.
611 At a later time, the packets can be filtered (again) and printed.
613 - BSD is supported. You must have BPF in your kernel.
614 Since the filtering is now done in the kernel, fewer packets are
615 dropped. In fact, with BPF and the packet dumper option, a measly
616 Sun 3/50 can keep up with a busy network.
618 - Compressed SLIP packets can now be dumped, provided you use our
619 SLIP software and BPF. These packets are dumped as any other IP
620 packet; the compressed headers are dumped with the '-e' option.
622 - Machines with little-endian byte ordering are supported (thanks to
625 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
627 - IBM RT and Stanford Enetfilter support has been added by
628 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
629 both the vanilla Enetfilter interface, and the extended interface
630 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
632 - TFTP packets are now printed (requests only).
634 - BOOTP packets are now printed.
636 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
638 - Sparc architectures, including the Sparcstation-1, are now
639 supported thanks to Steve McCanne and Craig Leres.
641 - SunOS 4 is now supported thanks to Micky Liu of Columbia
642 University (micky@cunixc.cc.columbia.edu).
644 - IP options are now printed.
646 - RIP packets are now printed.
648 - There's a -v flag that prints out more information than the
649 default (e.g., it will enable printing of IP ttl, tos and id)
650 and -q flag that prints out less (e.g., it will disable
651 interpretation of AppleTalk-in-UDP).
653 - The grammar has undergone substantial changes (if you have an
654 earlier version of tcpdump, you should re-read the manual
657 The most useful change is the addition of an expression
658 syntax that lets you filter on arbitrary fields or values in the
659 packet. E.g., "ip[0] > 0x45" would print only packets with IP
660 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
663 The most painful change is that concatenation no longer means
664 "and" -- e.g., you have to say "host foo and port bar" instead
665 of "host foo port bar". The up side to this down is that
666 repeated qualifiers can be omitted, making most filter
667 expressions shorter. E.g., you can now say "ip host foo and
668 (bar or baz)" to look at ip traffic between hosts foo and bar or
669 between hosts foo and baz. [The old way of saying this was "ip
670 host foo and (ip host bar or ip host baz)".]
