1452 - Redo configuration of "network" libraries (-lsocket and -lnsl) to
1453 deal with IRIX. Thanks to John Hawkinson (jhawk@mit.edu)
1455 - Added -a which tries to translate network and broadcast addresses to
1456 names. Suggested by Rob van Nieuwkerk (robn@verdi.et.tudelft.nl)
1458 - Added a configure option to disable gcc.
1460 - Added a "raw" packet printer.
1462 - Not having an interface address is no longer fatal. Requested by John

1468 using MD5 authentication. Thanks to Brian Wellington
1471 - Fix truncation check bugs in the Kerberos printer. Reported by Ezra
1472 Peisach (epeisach@mit.edu)
1474 - Don't catch SIGHUP when invoked with nohup(1). Thanks to Dave Plonka

1478 directory does not exist. Thanks to Dave Plonka.
1480 - Bit-swap FDDI addresses for BSD/OS too. Thanks to Paul Vixie
1483 - Fix off-by-one bug when testing size of ethernet packets. Thanks to
1484 Marty Leisner (leisner@sdsp.mc.xerox.com)
1486 - Add a local autoconf macro to check for routines in libraries; the
1487 autoconf version is broken (it only puts the library name in the
1488 cache variable name). Thanks to John Hawkinson.
1490 - Add a local autoconf macro to check for types; the autoconf version
1491 is broken (it uses grep instead of actually compiling a code fragment).
1493 - Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
1496 - Extend OSF ip header workaround to versions 1 and 2.
1498 - Fix some signed problems in the nfs printer. As reported by David
1499 Sacerdote (davids@silence.secnet.com)
1501 - Detect group wheel and use it as the default since BSD/OS' install
1502 can't hack numeric groups. Reported by David Sacerdote.
1504 - AIX needs special loader options. Thanks to Jonathan I. Kamens
1507 - Fixed the nfs printer to print port numbers in decimal. Thanks to

1530 - Add missing m4 quoting in AC_LBL_UNALIGNED_ACCESS autoconf macro.
1531 Reported by Joachim Ott (ott@ardala.han.de)
1533 - Enable "ip_hl vs. ip_vhl" workaround for OSF4 too.
1535 - Print arp hardware type in host order. Thanks to Onno van der Linden
1538 - Avoid solaris compiler warnings. Thanks to Bruce Barnett
1539 (barnett@grymoire.crd.ge.com)
1541 - Fix rip printer to not print one more route than is actually in the
1542 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
1543 Bill Fenner (fenner@parc.xerox.com)
1545 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
1547 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
1548 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1550 - Rewrite ospf printer to improve truncation checks.
1552 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1553 (davids@secnet.com). Also, check tcp options to make sure they ar
1554 actually in the tcp header (in addition to the normal truncation
1555 checks). Fix the SACK code to print the N blocks (instead of the
1556 first block N times).
1558 - Don't say really small UDP packets are truncated just because they
1559 aren't big enough to be a RPC. As noted by David Sacerdote.
1561 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1563 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1566 - Print mtu for icmp unreach need frag packets. Thanks to John
1567 Hawkinson (jhawk@mit.edu)
1569 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1572 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1573 (kushida@trl.ibm.co.jp)
1575 - Check igmp checksum if possible. Thanks to John Hawkinson.
1577 - Made changes for SINIX. Thanks to Andrej Borsenkow
1578 (borsenkow.msk@sni.de)
1580 - Use autoconf's idea of the top level directory in install targets.
1581 Thanks to John Hawkinson.
1583 - Avoid infinite loop in tcp options printing code. Thanks to Jeffrey
1584 Mogul (mogul@pa.dec.com)
1586 - Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
1587 Thanks to John Hawkinson.
1589 - Added some more packet truncation checks.
1591 - On systems that have it, use sigset() instead of signal() since
1592 signal() has different semantics on these systems.
1594 - Fixed some more alignment problems on the alpha.
1596 - Add code to massage unprintable characters in the domain and ipx
1597 printers. Thanks to John Hawkinson.
1599 - Added explicit netmask support. Thanks to Steve Nuchia
1600 (steve@research.oknet.com)
1602 - Add "sca" keyword (for DEC cluster services) as suggested by Terry
1603 Kennedy (terry@spcvxa.spc.edu)
1605 - Add "atalk" keyword as suggested by John Hawkinson.
1607 - Added an igrp printer. Thanks to Francis Dupont
1608 (francis.dupont@inria.fr)
1610 - Print IPX net numbers in hex a la Novell Netware. Thanks to Terry
1611 Kennedy (terry@spcvxa.spc.edu)
1613 - Fixed snmp extended tag field parsing bug. Thanks to Pascal Hennequin
1614 (pascal.hennequin@hugo.int-evry.fr)
1616 - Added some ETHERTYPEs missing on some systems.
1618 - Added truncated packet macros and various checks.
1620 - Fixed endian problems with the DECnet printer.
1622 - Use $CC when checking gcc version. Thanks to Carl Lindberg

1628 - Fix bugs in the autoconf misaligned accesses code fragment.
1630 - Include sys/param.h to get BYTE_ORDER in a few places. Thanks to
1631 Pavlin Ivanov Radoslavov (pavlin@cs.titech.ac.jp)
1633 v3.2 Sun Jun 23 02:28:10 PDT 1996
1635 - Print new icmp unreachable codes as suggested by Martin Fredriksson
1636 (martin@msp.se). Also print code value when unknown for icmp redirect
1639 - Fix an alignment endian bug in getname(). Thanks to John Hawkinson.
1641 - Define "new" domain record types if not found in arpa/nameserv.h.
1642 Resulted from a suggestion from John Hawkinson (jhawk@mit.edu). Also
1643 fixed an endian bug when printing mx record and added some new record
1646 - Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
1648 - Added T/TCP options printing. As suggested by Richard Stevens
1651 - Use autoconf to detect architectures that can't handle misaligned
1654 v3.1 Thu Jun 13 20:59:32 PDT 1996
1656 - Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
1657 and bind (as suggested by Charles Hannum).
1659 - Port to GNU autoconf.
1661 - Add support for printing DVMRP and PIM traffic thanks to
1662 Havard Eidnes (Havard.Eidnes@runit.sintef.no).
1664 - Fix AppleTalk, IPX and DECnet byte order problems due to wrong endian
1665 define being referenced. Reported by Terry Kennedy.
1667 - Minor fixes to the man page thanks to Mark Andrews.
1669 - Endian fixes to RTP and vat packet dumpers, thanks to Bruce Mah
1670 (bmah@cs.berkeley.edu).
1672 - Added support for new dns types, thanks to Rainer Orth.

1676 - Document -dd and -ddd. Resulted from a bug report from Charlie Slater
1677 (cslater@imatek.com).
1679 - Check return status from malloc/calloc/etc.
1681 - Check return status from pcap_loop() so we can print an error and
1682 exit with a bad status if there were problems.

1707 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1710 - Don't checksum ip header if we don't have all of it. Thanks to John
1711 Hawkinson (jhawk@mit.edu).
1713 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1714 Honig (jhc@bsdi.com)
1717 v3.1a1 Wed May 3 19:21:11 PDT 1995
1719 - Include time.h when SVR4 is defined to avoid problems under Solaris
1722 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1723 strings, not the local buffer. Thanks to Stefan Petri
1724 (petri@ibr.cs.tu-bs.de).
1726 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1727 that the selected value was not used. Thanks to Pascal Hennequin
1728 (Pascal.Hennequin@hugo.int-evry.fr).
1730 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1732 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1734 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1736 - Although there never was a 3.0.3 release, the linux boys cleverly
1737 "released" one in late 1995.
1739 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1741 - Change configuration to not use gcc v2 flags with gcc v1.
1743 - Redo gmt2local() so that it works under BSDI (which seems to return
1744 an empty timezone struct from gettimeofday()). Based on report from
1745 Terry Kennedy (terry@spcvxa.spc.edu).
1747 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1748 on report from Mark Andrews (mandrews@alias.com).
1750 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1751 Orth (ro@techfak.uni-bielefeld.de).
1753 - Fixed printout of connection id for uncompressed tcp slip packets.
1754 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1756 - Hack around deficiency in Ultrix's make.
1758 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1760 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1762 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1764 v3.0 Mon Jun 20 19:23:27 PDT 1994
1766 - Added support for printing tcp option timestamps thanks to
1767 Mark Andrews (mandrews@alias.com).
1769 - Reorganize protocol dumpers to take const pointers to packets so they
1770 never change the contents (i.e., they used to do endian conversions
1771 in place). Previously, whenever more than one pass was taken over
1772 the packet, the packet contents would be dumped incorrectly (i.e.,
1773 the output form -x would be wrong on little endian machines because
1774 the protocol dumpers would modify the data). Thanks to Charles Hannum
1775 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1777 - Added support for decnet protocol dumping thanks to Jeff Mogul
1780 - Fix bug that caused length of packet to be incorrectly printed
1781 (off by ether header size) for unknown ethernet types thanks
1782 to Greg Miller (gmiller@kayak.mitre.org).
1784 - Added support for IPX protocol dumping thanks to Brad Parker
1787 - Added check to verify IP header checksum under -v thanks to
1788 Brad Parker (brad@fcr.com).
1790 - Move packet capture code to new libpcap library (which is
1791 packaged separately).
1793 - Prototype everything and assume an ansi compiler.
1795 - print-arp.c: Print hardware ethernet addresses if they're not
1798 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1799 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1801 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1804 - print-icmp.c: Byte swap netmask before printing. Thanks to
1805 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1807 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1808 By default, only the inner packet is dumped, appended with the token
1809 "(encap)". Under -v, both the inner and output packets are dumped
1810 (on the same line). Note that the filter applies to the original packet,
1811 not the encapsulated packet. So if you run tcpdump on a net with an
1812 IP Multicast tunnel, you cannot filter out the datagrams using the
1813 conventional syntax. (You can filter away all the ip-in-ip traffic
1814 with "not ip proto 4".)
1816 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1817 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1819 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1821 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1822 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1823 Add && and || operators
1825 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1827 - Fix bug with -c flag.
1829 v2.2 Fri May 22 17:19:41 PDT 1992
1831 - savefile.c: Remove hack that shouldn't have been exported. Add
1834 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1835 matches non-echo/reply ICMP packets.
1837 - Many improvements to filter code optimizer.
1839 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1840 so that protocol qualifications are allowed. For example, "ip broadcast"
1841 and "ether multicast" are valid filters.
1843 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1844 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1845 patches to netinet/if_loop.c.
1847 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1848 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1850 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1852 v2.1 Tue Jan 28 11:00:14 PST 1992
1854 - Internal release (never publicly exported).
1856 v2.0.1 Sun Jan 26 21:10:10 PDT
1858 - Various byte ordering fixes.
1860 - Add truncation checks.
1862 - inet.c: Support BSD style SIOCGIFCONF.
1864 - nametoaddr.c: Handle multi addresses for single host.
1866 - optimize.c: Rewritten.
1868 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1871 - print-atal.c: Fix an alignment bug (thanks to
1872 stanonik@nprdc.navy.mil) Add missing printf() argument.
1874 - print-bootp.c: First attempt at decoding the vendor buffer.
1876 - print-domain.c: Fix truncation checks.
1878 - print-icmp.c: Calculate length of packets from the ip header.
1880 - print-ip.c: Print frag id in decimal (so it's easier to match up
1881 with non-frags). Add support for ospf, egp and igmp.
1883 - print-nfs.c: Lots of changes.
1885 - print-ntp.c: Make some verbose output depend on -v.
1887 - print-snmp.c: New version from John LoVerso.
1889 - print-tcp.c: Print rfc1072 tcp options.
1891 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1892 (microseconds) worth of precision. Fix uid bugs.
1894 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1895 With this option, you can create an architecture independent binary
1896 trace file in real time, without the overhead of the packet printer.
1897 At a later time, the packets can be filtered (again) and printed.
1899 - BSD is supported. You must have BPF in your kernel.
1900 Since the filtering is now done in the kernel, fewer packets are
1901 dropped. In fact, with BPF and the packet dumper option, a measly
1902 Sun 3/50 can keep up with a busy network.
1904 - Compressed SLIP packets can now be dumped, provided you use our
1905 SLIP software and BPF. These packets are dumped as any other IP
1906 packet; the compressed headers are dumped with the '-e' option.
1908 - Machines with little-endian byte ordering are supported (thanks to
1911 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1913 - IBM RT and Stanford Enetfilter support has been added by
1914 Rayan Zachariassen <rayan@canet.ca>. tcpdump has been tested under
1915 both the vanilla Enetfilter interface, and the extended interface
1916 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1918 - TFTP packets are now printed (requests only).
1920 - BOOTP packets are now printed.
1922 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1924 - Sparc architectures, including the Sparcstation-1, are now
1925 supported thanks to Steve McCanne and Craig Leres.
1927 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1928 University (micky@cunixc.cc.columbia.edu).
1930 - IP options are now printed.
1932 - RIP packets are now printed.
1934 - There's a -v flag that prints out more information than the
1935 default (e.g., it will enable printing of IP ttl, tos and id)
1936 and -q flag that prints out less (e.g., it will disable
1937 interpretation of AppleTalk-in-UDP).
1939 - The grammar has undergone substantial changes (if you have an
1940 earlier version of tcpdump, you should re-read the manual
1943 The most useful change is the addition of an expression
1944 syntax that lets you filter on arbitrary fields or values in the
1945 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1946 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1949 The most painful change is that concatenation no longer means
1950 "and" -- e.g., you have to say "host foo and port bar" instead
1951 of "host foo port bar". The up side to this down is that
1952 repeated qualifiers can be omitted, making most filter
1953 expressions shorter. E.g., you can now say "ip host foo and
1954 (bar or baz)" to look at ip traffic between hosts foo and bar or
1955 between hosts foo and baz. [The old way of saying this was "ip
1956 host foo and (ip host bar or ip host baz)".]
1958 v2.0 Sun Jan 13 12:20:40 PST 1991
1960 - Initial public release.
