1512 Marty Leisner (leisner@sdsp.mc.xerox.com)
1514 - Add a local autoconf macro to check for routines in libraries; the
1515 autoconf version is broken (it only puts the library name in the
1516 cache variable name). Thanks to John Hawkinson.
1518 - Add a local autoconf macro to check for types; the autoconf version
1519 is broken (it uses grep instead of actually compiling a code fragment).
1521 - Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
1524 - Extend OSF ip header workaround to versions 1 and 2.
1526 - Fix some signed problems in the nfs printer. As reported by David

1566 - Avoid solaris compiler warnings. Thanks to Bruce Barnett
1567 (barnett@grymoire.crd.ge.com)
1569 - Fix rip printer to not print one more route than is actually in the
1570 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
1571 Bill Fenner (fenner@parc.xerox.com)
1573 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
1575 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
1576 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1578 - Rewrite ospf printer to improve truncation checks.
1580 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1581 (davids@secnet.com). Also, check tcp options to make sure they ar
1582 actually in the tcp header (in addition to the normal truncation
1583 checks). Fix the SACK code to print the N blocks (instead of the
1584 first block N times).
1586 - Don't say really small UDP packets are truncated just because they
1587 aren't big enough to be a RPC. As noted by David Sacerdote.
1589 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1591 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1594 - Print mtu for icmp unreach need frag packets. Thanks to John
1595 Hawkinson (jhawk@mit.edu)
1597 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1600 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1601 (kushida@trl.ibm.co.jp)
1603 - Check igmp checksum if possible. Thanks to John Hawkinson.
1605 - Made changes for SINIX. Thanks to Andrej Borsenkow

1615 Thanks to John Hawkinson.
1617 - Added some more packet truncation checks.

1620 signal() has different semantics on these systems.
1622 - Fixed some more alignment problems on the alpha.
1624 - Add code to massage unprintable characters in the domain and ipx
1625 printers. Thanks to John Hawkinson.

1735 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1738 - Don't checksum ip header if we don't have all of it. Thanks to John
1739 Hawkinson (jhawk@mit.edu).
1741 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1742 Honig (jhc@bsdi.com)
1745 v3.1a1 Wed May 3 19:21:11 PDT 1995
1747 - Include time.h when SVR4 is defined to avoid problems under Solaris
1750 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1751 strings, not the local buffer. Thanks to Stefan Petri
1752 (petri@ibr.cs.tu-bs.de).
1754 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1755 that the selected value was not used. Thanks to Pascal Hennequin
1756 (Pascal.Hennequin@hugo.int-evry.fr).
1758 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1760 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1762 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1764 - Although there never was a 3.0.3 release, the linux boys cleverly
1765 "released" one in late 1995.
1767 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1769 - Change configuration to not use gcc v2 flags with gcc v1.
1771 - Redo gmt2local() so that it works under BSDI (which seems to return
1772 an empty timezone struct from gettimeofday()). Based on report from
1773 Terry Kennedy (terry@spcvxa.spc.edu).
1775 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1776 on report from Mark Andrews (mandrews@alias.com).
1778 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1779 Orth (ro@techfak.uni-bielefeld.de).
1781 - Fixed printout of connection id for uncompressed tcp slip packets.
1782 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1784 - Hack around deficiency in Ultrix's make.
1786 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1788 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1790 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1792 v3.0 Mon Jun 20 19:23:27 PDT 1994
1794 - Added support for printing tcp option timestamps thanks to
1795 Mark Andrews (mandrews@alias.com).
1797 - Reorganize protocol dumpers to take const pointers to packets so they
1798 never change the contents (i.e., they used to do endian conversions
1799 in place). Previously, whenever more than one pass was taken over
1800 the packet, the packet contents would be dumped incorrectly (i.e.,
1801 the output form -x would be wrong on little endian machines because
1802 the protocol dumpers would modify the data). Thanks to Charles Hannum
1803 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1805 - Added support for decnet protocol dumping thanks to Jeff Mogul
1808 - Fix bug that caused length of packet to be incorrectly printed
1809 (off by ether header size) for unknown ethernet types thanks
1810 to Greg Miller (gmiller@kayak.mitre.org).
1812 - Added support for IPX protocol dumping thanks to Brad Parker
1815 - Added check to verify IP header checksum under -v thanks to
1816 Brad Parker (brad@fcr.com).
1818 - Move packet capture code to new libpcap library (which is
1819 packaged separately).
1821 - Prototype everything and assume an ansi compiler.
1823 - print-arp.c: Print hardware ethernet addresses if they're not
1826 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1827 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1829 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1832 - print-icmp.c: Byte swap netmask before printing. Thanks to
1833 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1835 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1836 By default, only the inner packet is dumped, appended with the token
1837 "(encap)". Under -v, both the inner and output packets are dumped
1838 (on the same line). Note that the filter applies to the original packet,
1839 not the encapsulated packet. So if you run tcpdump on a net with an
1840 IP Multicast tunnel, you cannot filter out the datagrams using the
1841 conventional syntax. (You can filter away all the ip-in-ip traffic
1842 with "not ip proto 4".)
1844 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1845 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1847 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1849 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1850 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1851 Add && and || operators
1853 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1855 - Fix bug with -c flag.
1857 v2.2 Fri May 22 17:19:41 PDT 1992
1859 - savefile.c: Remove hack that shouldn't have been exported. Add
1862 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1863 matches non-echo/reply ICMP packets.
1865 - Many improvements to filter code optimizer.
1867 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1868 so that protocol qualifications are allowed. For example, "ip broadcast"
1869 and "ether multicast" are valid filters.
1871 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1872 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1873 patches to netinet/if_loop.c.
1875 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1876 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1878 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1880 v2.1 Tue Jan 28 11:00:14 PST 1992
1882 - Internal release (never publicly exported).
1884 v2.0.1 Sun Jan 26 21:10:10 PDT
1886 - Various byte ordering fixes.
1888 - Add truncation checks.
1890 - inet.c: Support BSD style SIOCGIFCONF.
1892 - nametoaddr.c: Handle multi addresses for single host.
1894 - optimize.c: Rewritten.
1896 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1899 - print-atal.c: Fix an alignment bug (thanks to
1900 stanonik@nprdc.navy.mil) Add missing printf() argument.
1902 - print-bootp.c: First attempt at decoding the vendor buffer.
1904 - print-domain.c: Fix truncation checks.
1906 - print-icmp.c: Calculate length of packets from the ip header.
1908 - print-ip.c: Print frag id in decimal (so it's easier to match up
1909 with non-frags). Add support for ospf, egp and igmp.
1911 - print-nfs.c: Lots of changes.
1913 - print-ntp.c: Make some verbose output depend on -v.
1915 - print-snmp.c: New version from John LoVerso.
1917 - print-tcp.c: Print rfc1072 tcp options.
1919 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1920 (microseconds) worth of precision. Fix uid bugs.
1922 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1923 With this option, you can create an architecture independent binary
1924 trace file in real time, without the overhead of the packet printer.
1925 At a later time, the packets can be filtered (again) and printed.
1927 - BSD is supported. You must have BPF in your kernel.
1928 Since the filtering is now done in the kernel, fewer packets are
1929 dropped. In fact, with BPF and the packet dumper option, a measly
1930 Sun 3/50 can keep up with a busy network.
1932 - Compressed SLIP packets can now be dumped, provided you use our
1933 SLIP software and BPF. These packets are dumped as any other IP
1934 packet; the compressed headers are dumped with the '-e' option.
1936 - Machines with little-endian byte ordering are supported (thanks to
1939 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1941 - IBM RT and Stanford Enetfilter support has been added by
1942 Rayan Zachariassen <rayan@canet.ca>. tcpdump has been tested under
1943 both the vanilla Enetfilter interface, and the extended interface
1944 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1946 - TFTP packets are now printed (requests only).
1948 - BOOTP packets are now printed.
1950 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1952 - Sparc architectures, including the Sparcstation-1, are now
1953 supported thanks to Steve McCanne and Craig Leres.
1955 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1956 University (micky@cunixc.cc.columbia.edu).
1958 - IP options are now printed.
1960 - RIP packets are now printed.
1962 - There's a -v flag that prints out more information than the
1963 default (e.g., it will enable printing of IP ttl, tos and id)
1964 and -q flag that prints out less (e.g., it will disable
1965 interpretation of AppleTalk-in-UDP).
1967 - The grammar has undergone substantial changes (if you have an
1968 earlier version of tcpdump, you should re-read the manual
1971 The most useful change is the addition of an expression
1972 syntax that lets you filter on arbitrary fields or values in the
1973 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1974 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1977 The most painful change is that concatenation no longer means
1978 "and" -- e.g., you have to say "host foo and port bar" instead
1979 of "host foo port bar". The up side to this down is that
1980 repeated qualifiers can be omitted, making most filter
1981 expressions shorter. E.g., you can now say "ip host foo and
1982 (bar or baz)" to look at ip traffic between hosts foo and bar or
1983 between hosts foo and baz. [The old way of saying this was "ip
1984 host foo and (ip host bar or ip host baz)".]
1986 v2.0 Sun Jan 13 12:20:40 PST 1991
1988 - Initial public release.
