1370 checks). Fix the SACK code to print the N blocks (instead of the
1371 first block N times).
1373 - Don't say really small UDP packets are truncated just because they
1374 aren't big enough to be a RPC. As noted by David Sacerdote.

1549 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1551 - Although there never was a 3.0.3 release, the linux boys cleverly
1552 "released" one in late 1995.
1554 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1556 - Change configuration to not use gcc v2 flags with gcc v1.
1558 - Redo gmt2local() so that it works under BSDI (which seems to return
1559 an empty timezone struct from gettimeofday()). Based on report from
1560 Terry Kennedy (terry@spcvxa.spc.edu).
1562 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1563 on report from Mark Andrews (mandrews@alias.com).
1565 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1566 Orth (ro@techfak.uni-bielefeld.de).
1568 - Fixed printout of connection id for uncompressed tcp slip packets.
1569 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1571 - Hack around deficiency in Ultrix's make.
1573 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1575 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1577 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1579 v3.0 Mon Jun 20 19:23:27 PDT 1994
1581 - Added support for printing tcp option timestamps thanks to
1582 Mark Andrews (mandrews@alias.com).
1584 - Reorganize protocol dumpers to take const pointers to packets so they
1585 never change the contents (i.e., they used to do endian conversions
1586 in place). Previously, whenever more than one pass was taken over
1587 the packet, the packet contents would be dumped incorrectly (i.e.,
1588 the output form -x would be wrong on little endian machines because
1589 the protocol dumpers would modify the data). Thanks to Charles Hannum
1590 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1592 - Added support for decnet protocol dumping thanks to Jeff Mogul
1595 - Fix bug that caused length of packet to be incorrectly printed
1596 (off by ether header size) for unknown ethernet types thanks
1597 to Greg Miller (gmiller@kayak.mitre.org).
1599 - Added support for IPX protocol dumping thanks to Brad Parker
1602 - Added check to verify IP header checksum under -v thanks to
1603 Brad Parker (brad@fcr.com).
1605 - Move packet capture code to new libpcap library (which is
1606 packaged separately).
1608 - Prototype everything and assume an ansi compiler.
1610 - print-arp.c: Print hardware ethernet addresses if they're not
1613 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1614 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1616 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1619 - print-icmp.c: Byte swap netmask before printing. Thanks to
1620 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1622 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1623 By default, only the inner packet is dumped, appended with the token
1624 "(encap)". Under -v, both the inner and output packets are dumped
1625 (on the same line). Note that the filter applies to the original packet,
1626 not the encapsulated packet. So if you run tcpdump on a net with an
1627 IP Multicast tunnel, you cannot filter out the datagrams using the
1628 conventional syntax. (You can filter away all the ip-in-ip traffic
1629 with "not ip proto 4".)
1631 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1632 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1634 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1636 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1637 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1638 Add && and || operators
1640 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1642 - Fix bug with -c flag.
1644 v2.2 Fri May 22 17:19:41 PDT 1992
1646 - savefile.c: Remove hack that shouldn't have been exported. Add
1649 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1650 matches non-echo/reply ICMP packets.
1652 - Many improvements to filter code optimizer.
1654 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1655 so that protocol qualifications are allowed. For example, "ip broadcast"
1656 and "ether multicast" are valid filters.
1658 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1659 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1660 patches to netinet/if_loop.c.
1662 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1663 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1665 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1667 v2.1 Tue Jan 28 11:00:14 PST 1992
1669 - Internal release (never publicly exported).
1671 v2.0.1 Sun Jan 26 21:10:10 PDT
1673 - Various byte ordering fixes.
1675 - Add truncation checks.
1677 - inet.c: Support BSD style SIOCGIFCONF.
1679 - nametoaddr.c: Handle multi addresses for single host.
1681 - optimize.c: Rewritten.
1683 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1686 - print-atal.c: Fix an alignment bug (thanks to
1687 stanonik@nprdc.navy.mil) Add missing printf() argument.
1689 - print-bootp.c: First attempt at decoding the vendor buffer.
1691 - print-domain.c: Fix truncation checks.
1693 - print-icmp.c: Calculate length of packets from the ip header.
1695 - print-ip.c: Print frag id in decimal (so it's easier to match up
1696 with non-frags). Add support for ospf, egp and igmp.
1698 - print-nfs.c: Lots of changes.
1700 - print-ntp.c: Make some verbose output depend on -v.
1702 - print-snmp.c: New version from John LoVerso.
1704 - print-tcp.c: Print rfc1072 tcp options.
1706 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1707 (microseconds) worth of precision. Fix uid bugs.
1709 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1710 With this option, you can create an architecture independent binary
1711 trace file in real time, without the overhead of the packet printer.
1712 At a later time, the packets can be filtered (again) and printed.
1714 - BSD is supported. You must have BPF in your kernel.
1715 Since the filtering is now done in the kernel, fewer packets are
1716 dropped. In fact, with BPF and the packet dumper option, a measly
1717 Sun 3/50 can keep up with a busy network.
1719 - Compressed SLIP packets can now be dumped, provided you use our
1720 SLIP software and BPF. These packets are dumped as any other IP
1721 packet; the compressed headers are dumped with the '-e' option.
1723 - Machines with little-endian byte ordering are supported (thanks to
1726 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1728 - IBM RT and Stanford Enetfilter support has been added by
1729 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1730 both the vanilla Enetfilter interface, and the extended interface
1731 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1733 - TFTP packets are now printed (requests only).
1735 - BOOTP packets are now printed.
1737 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1739 - Sparc architectures, including the Sparcstation-1, are now
1740 supported thanks to Steve McCanne and Craig Leres.
1742 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1743 University (micky@cunixc.cc.columbia.edu).
1745 - IP options are now printed.
1747 - RIP packets are now printed.
1749 - There's a -v flag that prints out more information than the
1750 default (e.g., it will enable printing of IP ttl, tos and id)
1751 and -q flag that prints out less (e.g., it will disable
1752 interpretation of AppleTalk-in-UDP).
1754 - The grammar has undergone substantial changes (if you have an
1755 earlier version of tcpdump, you should re-read the manual
1758 The most useful change is the addition of an expression
1759 syntax that lets you filter on arbitrary fields or values in the
1760 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1761 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1764 The most painful change is that concatenation no longer means
1765 "and" -- e.g., you have to say "host foo and port bar" instead
1766 of "host foo port bar". The up side to this down is that
1767 repeated qualifiers can be omitted, making most filter
1768 expressions shorter. E.g., you can now say "ip host foo and
1769 (bar or baz)" to look at ip traffic between hosts foo and bar or
1770 between hosts foo and baz. [The old way of saying this was "ip
1771 host foo and (ip host bar or ip host baz)".]
