1511 Marty Leisner (leisner@sdsp.mc.xerox.com)
1513 - Add a local autoconf macro to check for routines in libraries; the
1514 autoconf version is broken (it only puts the library name in the
1515 cache variable name). Thanks to John Hawkinson.
1517 - Add a local autoconf macro to check for types; the autoconf version
1518 is broken (it uses grep instead of actually compiling a code fragment).
1520 - Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header

1560 - Enable "ip_hl vs. ip_vhl" workaround for OSF4 too.
1562 - Print arp hardware type in host order. Thanks to Onno van der Linden
1565 - Avoid solaris compiler warnings. Thanks to Bruce Barnett
1566 (barnett@grymoire.crd.ge.com)
1568 - Fix rip printer to not print one more route than is actually in the
1569 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
1570 Bill Fenner (fenner@parc.xerox.com)
1572 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
1574 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
1575 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1577 - Rewrite ospf printer to improve truncation checks.
1579 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1580 (davids@secnet.com). Also, check tcp options to make sure they ar
1581 actually in the tcp header (in addition to the normal truncation
1582 checks). Fix the SACK code to print the N blocks (instead of the
1583 first block N times).
1585 - Don't say really small UDP packets are truncated just because they
1586 aren't big enough to be a RPC. As noted by David Sacerdote.
1588 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1590 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1593 - Print mtu for icmp unreach need frag packets. Thanks to John
1594 Hawkinson (jhawk@mit.edu)
1596 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1599 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1600 (kushida@trl.ibm.co.jp)
1602 - Check igmp checksum if possible. Thanks to John Hawkinson.
1604 - Made changes for SINIX. Thanks to Andrej Borsenkow
1605 (borsenkow.msk@sni.de)

1614 Thanks to John Hawkinson.
1616 - Added some more packet truncation checks.

1619 signal() has different semantics on these systems.
1621 - Fixed some more alignment problems on the alpha.
1623 - Add code to massage unprintable characters in the domain and ipx
1624 printers. Thanks to John Hawkinson.

1734 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1737 - Don't checksum ip header if we don't have all of it. Thanks to John
1738 Hawkinson (jhawk@mit.edu).
1740 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1741 Honig (jhc@bsdi.com)
1744 v3.1a1 Wed May 3 19:21:11 PDT 1995
1746 - Include time.h when SVR4 is defined to avoid problems under Solaris
1749 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1750 strings, not the local buffer. Thanks to Stefan Petri
1751 (petri@ibr.cs.tu-bs.de).
1753 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1754 that the selected value was not used. Thanks to Pascal Hennequin
1755 (Pascal.Hennequin@hugo.int-evry.fr).
1757 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1759 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1761 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1763 - Although there never was a 3.0.3 release, the linux boys cleverly
1764 "released" one in late 1995.
1766 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1768 - Change configuration to not use gcc v2 flags with gcc v1.
1770 - Redo gmt2local() so that it works under BSDI (which seems to return
1771 an empty timezone struct from gettimeofday()). Based on report from
1772 Terry Kennedy (terry@spcvxa.spc.edu).
1774 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1775 on report from Mark Andrews (mandrews@alias.com).
1777 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1778 Orth (ro@techfak.uni-bielefeld.de).
1780 - Fixed printout of connection id for uncompressed tcp slip packets.
1781 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1783 - Hack around deficiency in Ultrix's make.
1785 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1787 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1789 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1791 v3.0 Mon Jun 20 19:23:27 PDT 1994
1793 - Added support for printing tcp option timestamps thanks to
1794 Mark Andrews (mandrews@alias.com).
1796 - Reorganize protocol dumpers to take const pointers to packets so they
1797 never change the contents (i.e., they used to do endian conversions
1798 in place). Previously, whenever more than one pass was taken over
1799 the packet, the packet contents would be dumped incorrectly (i.e.,
1800 the output form -x would be wrong on little endian machines because
1801 the protocol dumpers would modify the data). Thanks to Charles Hannum
1802 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1804 - Added support for decnet protocol dumping thanks to Jeff Mogul
1807 - Fix bug that caused length of packet to be incorrectly printed
1808 (off by ether header size) for unknown ethernet types thanks
1809 to Greg Miller (gmiller@kayak.mitre.org).
1811 - Added support for IPX protocol dumping thanks to Brad Parker
1814 - Added check to verify IP header checksum under -v thanks to
1815 Brad Parker (brad@fcr.com).
1817 - Move packet capture code to new libpcap library (which is
1818 packaged separately).
1820 - Prototype everything and assume an ansi compiler.
1822 - print-arp.c: Print hardware ethernet addresses if they're not
1825 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1826 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1828 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1831 - print-icmp.c: Byte swap netmask before printing. Thanks to
1832 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1834 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1835 By default, only the inner packet is dumped, appended with the token
1836 "(encap)". Under -v, both the inner and output packets are dumped
1837 (on the same line). Note that the filter applies to the original packet,
1838 not the encapsulated packet. So if you run tcpdump on a net with an
1839 IP Multicast tunnel, you cannot filter out the datagrams using the
1840 conventional syntax. (You can filter away all the ip-in-ip traffic
1841 with "not ip proto 4".)
1843 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1844 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1846 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1848 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1849 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1850 Add && and || operators
1852 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1854 - Fix bug with -c flag.
1856 v2.2 Fri May 22 17:19:41 PDT 1992
1858 - savefile.c: Remove hack that shouldn't have been exported. Add
1861 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1862 matches non-echo/reply ICMP packets.
1864 - Many improvements to filter code optimizer.
1866 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1867 so that protocol qualifications are allowed. For example, "ip broadcast"
1868 and "ether multicast" are valid filters.
1870 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1871 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1872 patches to netinet/if_loop.c.
1874 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1875 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1877 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1879 v2.1 Tue Jan 28 11:00:14 PST 1992
1881 - Internal release (never publicly exported).
1883 v2.0.1 Sun Jan 26 21:10:10 PDT
1885 - Various byte ordering fixes.
1887 - Add truncation checks.
1889 - inet.c: Support BSD style SIOCGIFCONF.
1891 - nametoaddr.c: Handle multi addresses for single host.
1893 - optimize.c: Rewritten.
1895 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1898 - print-atal.c: Fix an alignment bug (thanks to
1899 stanonik@nprdc.navy.mil) Add missing printf() argument.
1901 - print-bootp.c: First attempt at decoding the vendor buffer.
1903 - print-domain.c: Fix truncation checks.
1905 - print-icmp.c: Calculate length of packets from the ip header.
1907 - print-ip.c: Print frag id in decimal (so it's easier to match up
1908 with non-frags). Add support for ospf, egp and igmp.
1910 - print-nfs.c: Lots of changes.
1912 - print-ntp.c: Make some verbose output depend on -v.
1914 - print-snmp.c: New version from John LoVerso.
1916 - print-tcp.c: Print rfc1072 tcp options.
1918 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1919 (microseconds) worth of precision. Fix uid bugs.
1921 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1922 With this option, you can create an architecture independent binary
1923 trace file in real time, without the overhead of the packet printer.
1924 At a later time, the packets can be filtered (again) and printed.
1926 - BSD is supported. You must have BPF in your kernel.
1927 Since the filtering is now done in the kernel, fewer packets are
1928 dropped. In fact, with BPF and the packet dumper option, a measly
1929 Sun 3/50 can keep up with a busy network.
1931 - Compressed SLIP packets can now be dumped, provided you use our
1932 SLIP software and BPF. These packets are dumped as any other IP
1933 packet; the compressed headers are dumped with the '-e' option.
1935 - Machines with little-endian byte ordering are supported (thanks to
1938 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1940 - IBM RT and Stanford Enetfilter support has been added by
1941 Rayan Zachariassen <rayan@canet.ca>. tcpdump has been tested under
1942 both the vanilla Enetfilter interface, and the extended interface
1943 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1945 - TFTP packets are now printed (requests only).
1947 - BOOTP packets are now printed.
1949 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1951 - Sparc architectures, including the Sparcstation-1, are now
1952 supported thanks to Steve McCanne and Craig Leres.
1954 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1955 University (micky@cunixc.cc.columbia.edu).
1957 - IP options are now printed.
1959 - RIP packets are now printed.
1961 - There's a -v flag that prints out more information than the
1962 default (e.g., it will enable printing of IP ttl, tos and id)
1963 and -q flag that prints out less (e.g., it will disable
1964 interpretation of AppleTalk-in-UDP).
1966 - The grammar has undergone substantial changes (if you have an
1967 earlier version of tcpdump, you should re-read the manual
1970 The most useful change is the addition of an expression
1971 syntax that lets you filter on arbitrary fields or values in the
1972 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1973 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1976 The most painful change is that concatenation no longer means
1977 "and" -- e.g., you have to say "host foo and port bar" instead
1978 of "host foo port bar". The up side to this down is that
1979 repeated qualifiers can be omitted, making most filter
1980 expressions shorter. E.g., you can now say "ip host foo and
1981 (bar or baz)" to look at ip traffic between hosts foo and bar or
1982 between hosts foo and baz. [The old way of saying this was "ip
1983 host foo and (ip host bar or ip host baz)".]
1985 v2.0 Sun Jan 13 12:20:40 PST 1991
1987 - Initial public release.
