1510 Marty Leisner (leisner@sdsp.mc.xerox.com)
1512 - Add a local autoconf macro to check for routines in libraries; the
1513 autoconf version is broken (it only puts the library name in the
1514 cache variable name). Thanks to John Hawkinson.
1516 - Add a local autoconf macro to check for types; the autoconf version
1517 is broken (it uses grep instead of actually compiling a code fragment).
1519 - Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header

1561 - Print arp hardware type in host order. Thanks to Onno van der Linden
1564 - Avoid solaris compiler warnings. Thanks to Bruce Barnett
1565 (barnett@grymoire.crd.ge.com)
1567 - Fix rip printer to not print one more route than is actually in the
1568 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and

1571 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
1573 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
1574 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1576 - Rewrite ospf printer to improve truncation checks.
1578 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1579 (davids@secnet.com). Also, check tcp options to make sure they ar
1580 actually in the tcp header (in addition to the normal truncation
1581 checks). Fix the SACK code to print the N blocks (instead of the
1582 first block N times).
1584 - Don't say really small UDP packets are truncated just because they
1585 aren't big enough to be a RPC. As noted by David Sacerdote.
1587 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1589 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1592 - Print mtu for icmp unreach need frag packets. Thanks to John
1593 Hawkinson (jhawk@mit.edu)
1595 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1598 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1599 (kushida@trl.ibm.co.jp)
1601 - Check igmp checksum if possible. Thanks to John Hawkinson.
1603 - Made changes for SINIX. Thanks to Andrej Borsenkow
1604 (borsenkow.msk@sni.de)

1613 Thanks to John Hawkinson.
1615 - Added some more packet truncation checks.

1618 signal() has different semantics on these systems.
1620 - Fixed some more alignment problems on the alpha.
1622 - Add code to massage unprintable characters in the domain and ipx
1623 printers. Thanks to John Hawkinson.

1733 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1736 - Don't checksum ip header if we don't have all of it. Thanks to John
1737 Hawkinson (jhawk@mit.edu).
1739 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1740 Honig (jhc@bsdi.com)
1743 v3.1a1 Wed May 3 19:21:11 PDT 1995
1745 - Include time.h when SVR4 is defined to avoid problems under Solaris
1748 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1749 strings, not the local buffer. Thanks to Stefan Petri
1750 (petri@ibr.cs.tu-bs.de).
1752 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1753 that the selected value was not used. Thanks to Pascal Hennequin
1754 (Pascal.Hennequin@hugo.int-evry.fr).
1756 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1758 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1760 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1762 - Although there never was a 3.0.3 release, the linux boys cleverly
1763 "released" one in late 1995.
1765 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1767 - Change configuration to not use gcc v2 flags with gcc v1.
1769 - Redo gmt2local() so that it works under BSDI (which seems to return
1770 an empty timezone struct from gettimeofday()). Based on report from
1771 Terry Kennedy (terry@spcvxa.spc.edu).
1773 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1774 on report from Mark Andrews (mandrews@alias.com).
1776 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1777 Orth (ro@techfak.uni-bielefeld.de).
1779 - Fixed printout of connection id for uncompressed tcp slip packets.
1780 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1782 - Hack around deficiency in Ultrix's make.
1784 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1786 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1788 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1790 v3.0 Mon Jun 20 19:23:27 PDT 1994
1792 - Added support for printing tcp option timestamps thanks to
1793 Mark Andrews (mandrews@alias.com).
1795 - Reorganize protocol dumpers to take const pointers to packets so they
1796 never change the contents (i.e., they used to do endian conversions
1797 in place). Previously, whenever more than one pass was taken over
1798 the packet, the packet contents would be dumped incorrectly (i.e.,
1799 the output form -x would be wrong on little endian machines because
1800 the protocol dumpers would modify the data). Thanks to Charles Hannum
1801 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1803 - Added support for decnet protocol dumping thanks to Jeff Mogul
1806 - Fix bug that caused length of packet to be incorrectly printed
1807 (off by ether header size) for unknown ethernet types thanks
1808 to Greg Miller (gmiller@kayak.mitre.org).
1810 - Added support for IPX protocol dumping thanks to Brad Parker
1813 - Added check to verify IP header checksum under -v thanks to
1814 Brad Parker (brad@fcr.com).
1816 - Move packet capture code to new libpcap library (which is
1817 packaged separately).
1819 - Prototype everything and assume an ansi compiler.
1821 - print-arp.c: Print hardware ethernet addresses if they're not
1824 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1825 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1827 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1830 - print-icmp.c: Byte swap netmask before printing. Thanks to
1831 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1833 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1834 By default, only the inner packet is dumped, appended with the token
1835 "(encap)". Under -v, both the inner and output packets are dumped
1836 (on the same line). Note that the filter applies to the original packet,
1837 not the encapsulated packet. So if you run tcpdump on a net with an
1838 IP Multicast tunnel, you cannot filter out the datagrams using the
1839 conventional syntax. (You can filter away all the ip-in-ip traffic
1840 with "not ip proto 4".)
1842 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1843 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1845 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1847 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1848 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1849 Add && and || operators
1851 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1853 - Fix bug with -c flag.
1855 v2.2 Fri May 22 17:19:41 PDT 1992
1857 - savefile.c: Remove hack that shouldn't have been exported. Add
1860 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1861 matches non-echo/reply ICMP packets.
1863 - Many improvements to filter code optimizer.
1865 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1866 so that protocol qualifications are allowed. For example, "ip broadcast"
1867 and "ether multicast" are valid filters.
1869 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1870 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1871 patches to netinet/if_loop.c.
1873 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1874 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1876 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1878 v2.1 Tue Jan 28 11:00:14 PST 1992
1880 - Internal release (never publicly exported).
1882 v2.0.1 Sun Jan 26 21:10:10 PDT
1884 - Various byte ordering fixes.
1886 - Add truncation checks.
1888 - inet.c: Support BSD style SIOCGIFCONF.
1890 - nametoaddr.c: Handle multi addresses for single host.
1892 - optimize.c: Rewritten.
1894 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1897 - print-atal.c: Fix an alignment bug (thanks to
1898 stanonik@nprdc.navy.mil) Add missing printf() argument.
1900 - print-bootp.c: First attempt at decoding the vendor buffer.
1902 - print-domain.c: Fix truncation checks.
1904 - print-icmp.c: Calculate length of packets from the ip header.
1906 - print-ip.c: Print frag id in decimal (so it's easier to match up
1907 with non-frags). Add support for ospf, egp and igmp.
1909 - print-nfs.c: Lots of changes.
1911 - print-ntp.c: Make some verbose output depend on -v.
1913 - print-snmp.c: New version from John LoVerso.
1915 - print-tcp.c: Print rfc1072 tcp options.
1917 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1918 (microseconds) worth of precision. Fix uid bugs.
1920 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1921 With this option, you can create an architecture independent binary
1922 trace file in real time, without the overhead of the packet printer.
1923 At a later time, the packets can be filtered (again) and printed.
1925 - BSD is supported. You must have BPF in your kernel.
1926 Since the filtering is now done in the kernel, fewer packets are
1927 dropped. In fact, with BPF and the packet dumper option, a measly
1928 Sun 3/50 can keep up with a busy network.
1930 - Compressed SLIP packets can now be dumped, provided you use our
1931 SLIP software and BPF. These packets are dumped as any other IP
1932 packet; the compressed headers are dumped with the '-e' option.
1934 - Machines with little-endian byte ordering are supported (thanks to
1937 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1939 - IBM RT and Stanford Enetfilter support has been added by
1940 Rayan Zachariassen <rayan@canet.ca>. tcpdump has been tested under
1941 both the vanilla Enetfilter interface, and the extended interface
1942 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1944 - TFTP packets are now printed (requests only).
1946 - BOOTP packets are now printed.
1948 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1950 - Sparc architectures, including the Sparcstation-1, are now
1951 supported thanks to Steve McCanne and Craig Leres.
1953 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1954 University (micky@cunixc.cc.columbia.edu).
1956 - IP options are now printed.
1958 - RIP packets are now printed.
1960 - There's a -v flag that prints out more information than the
1961 default (e.g., it will enable printing of IP ttl, tos and id)
1962 and -q flag that prints out less (e.g., it will disable
1963 interpretation of AppleTalk-in-UDP).
1965 - The grammar has undergone substantial changes (if you have an
1966 earlier version of tcpdump, you should re-read the manual
1969 The most useful change is the addition of an expression
1970 syntax that lets you filter on arbitrary fields or values in the
1971 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1972 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1975 The most painful change is that concatenation no longer means
1976 "and" -- e.g., you have to say "host foo and port bar" instead
1977 of "host foo port bar". The up side to this down is that
1978 repeated qualifiers can be omitted, making most filter
1979 expressions shorter. E.g., you can now say "ip host foo and
1980 (bar or baz)" to look at ip traffic between hosts foo and bar or
1981 between hosts foo and baz. [The old way of saying this was "ip
1982 host foo and (ip host bar or ip host baz)".]
1984 v2.0 Sun Jan 13 12:20:40 PST 1991
1986 - Initial public release.
