1465 - Detect group wheel and use it as the default since BSD/OS' install
1466 can't hack numeric groups. Reported by David Sacerdote.
1468 - AIX needs special loader options. Thanks to Jonathan I. Kamens
1471 - Fixed the nfs printer to print port numbers in decimal. Thanks to
1472 Kent Vander Velden (graphix@iastate.edu)

1503 (barnett@grymoire.crd.ge.com)
1505 - Fix rip printer to not print one more route than is actually in the
1506 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
1507 Bill Fenner (fenner@parc.xerox.com)
1509 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
1511 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
1512 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1514 - Rewrite ospf printer to improve truncation checks.
1516 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1517 (davids@secnet.com). Also, check tcp options to make sure they ar
1518 actually in the tcp header (in addition to the normal truncation
1519 checks). Fix the SACK code to print the N blocks (instead of the
1520 first block N times).
1522 - Don't say really small UDP packets are truncated just because they
1523 aren't big enough to be a RPC. As noted by David Sacerdote.

1551 Thanks to John Hawkinson.
1553 - Added some more packet truncation checks.

1629 define being referenced. Reported by Terry Kennedy.
1631 - Minor fixes to the man page thanks to Mark Andrews.
1633 - Endian fixes to RTP and vat packet dumpers, thanks to Bruce Mah

1671 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1674 - Don't checksum ip header if we don't have all of it. Thanks to John
1675 Hawkinson (jhawk@mit.edu).
1677 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1678 Honig (jhc@bsdi.com)
1681 v3.1a1 Wed May 3 19:21:11 PDT 1995
1683 - Include time.h when SVR4 is defined to avoid problems under Solaris
1686 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1687 strings, not the local buffer. Thanks to Stefan Petri
1688 (petri@ibr.cs.tu-bs.de).
1690 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1691 that the selected value was not used. Thanks to Pascal Hennequin
1692 (Pascal.Hennequin@hugo.int-evry.fr).
1694 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1696 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1698 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1700 - Although there never was a 3.0.3 release, the linux boys cleverly
1701 "released" one in late 1995.
1703 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1705 - Change configuration to not use gcc v2 flags with gcc v1.
1707 - Redo gmt2local() so that it works under BSDI (which seems to return
1708 an empty timezone struct from gettimeofday()). Based on report from
1709 Terry Kennedy (terry@spcvxa.spc.edu).
1711 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1712 on report from Mark Andrews (mandrews@alias.com).
1714 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1715 Orth (ro@techfak.uni-bielefeld.de).
1717 - Fixed printout of connection id for uncompressed tcp slip packets.
1718 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1720 - Hack around deficiency in Ultrix's make.
1722 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1724 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1726 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1728 v3.0 Mon Jun 20 19:23:27 PDT 1994
1730 - Added support for printing tcp option timestamps thanks to
1731 Mark Andrews (mandrews@alias.com).
1733 - Reorganize protocol dumpers to take const pointers to packets so they
1734 never change the contents (i.e., they used to do endian conversions
1735 in place). Previously, whenever more than one pass was taken over
1736 the packet, the packet contents would be dumped incorrectly (i.e.,
1737 the output form -x would be wrong on little endian machines because
1738 the protocol dumpers would modify the data). Thanks to Charles Hannum
1739 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1741 - Added support for decnet protocol dumping thanks to Jeff Mogul
1744 - Fix bug that caused length of packet to be incorrectly printed
1745 (off by ether header size) for unknown ethernet types thanks
1746 to Greg Miller (gmiller@kayak.mitre.org).
1748 - Added support for IPX protocol dumping thanks to Brad Parker
1751 - Added check to verify IP header checksum under -v thanks to
1752 Brad Parker (brad@fcr.com).
1754 - Move packet capture code to new libpcap library (which is
1755 packaged separately).
1757 - Prototype everything and assume an ansi compiler.
1759 - print-arp.c: Print hardware ethernet addresses if they're not
1762 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1763 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1765 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1768 - print-icmp.c: Byte swap netmask before printing. Thanks to
1769 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1771 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1772 By default, only the inner packet is dumped, appended with the token
1773 "(encap)". Under -v, both the inner and output packets are dumped
1774 (on the same line). Note that the filter applies to the original packet,
1775 not the encapsulated packet. So if you run tcpdump on a net with an
1776 IP Multicast tunnel, you cannot filter out the datagrams using the
1777 conventional syntax. (You can filter away all the ip-in-ip traffic
1778 with "not ip proto 4".)
1780 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1781 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1783 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1785 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1786 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1787 Add && and || operators
1789 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1791 - Fix bug with -c flag.
1793 v2.2 Fri May 22 17:19:41 PDT 1992
1795 - savefile.c: Remove hack that shouldn't have been exported. Add
1798 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1799 matches non-echo/reply ICMP packets.
1801 - Many improvements to filter code optimizer.
1803 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1804 so that protocol qualifications are allowed. For example, "ip broadcast"
1805 and "ether multicast" are valid filters.
1807 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1808 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1809 patches to netinet/if_loop.c.
1811 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1812 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1814 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1816 v2.1 Tue Jan 28 11:00:14 PST 1992
1818 - Internal release (never publicly exported).
1820 v2.0.1 Sun Jan 26 21:10:10 PDT
1822 - Various byte ordering fixes.
1824 - Add truncation checks.
1826 - inet.c: Support BSD style SIOCGIFCONF.
1828 - nametoaddr.c: Handle multi addresses for single host.
1830 - optimize.c: Rewritten.
1832 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1835 - print-atal.c: Fix an alignment bug (thanks to
1836 stanonik@nprdc.navy.mil) Add missing printf() argument.
1838 - print-bootp.c: First attempt at decoding the vendor buffer.
1840 - print-domain.c: Fix truncation checks.
1842 - print-icmp.c: Calculate length of packets from the ip header.
1844 - print-ip.c: Print frag id in decimal (so it's easier to match up
1845 with non-frags). Add support for ospf, egp and igmp.
1847 - print-nfs.c: Lots of changes.
1849 - print-ntp.c: Make some verbose output depend on -v.
1851 - print-snmp.c: New version from John LoVerso.
1853 - print-tcp.c: Print rfc1072 tcp options.
1855 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1856 (microseconds) worth of precision. Fix uid bugs.
1858 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1859 With this option, you can create an architecture independent binary
1860 trace file in real time, without the overhead of the packet printer.
1861 At a later time, the packets can be filtered (again) and printed.
1863 - BSD is supported. You must have BPF in your kernel.
1864 Since the filtering is now done in the kernel, fewer packets are
1865 dropped. In fact, with BPF and the packet dumper option, a measly
1866 Sun 3/50 can keep up with a busy network.
1868 - Compressed SLIP packets can now be dumped, provided you use our
1869 SLIP software and BPF. These packets are dumped as any other IP
1870 packet; the compressed headers are dumped with the '-e' option.
1872 - Machines with little-endian byte ordering are supported (thanks to
1875 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1877 - IBM RT and Stanford Enetfilter support has been added by
1878 Rayan Zachariassen <rayan@canet.ca>. tcpdump has been tested under
1879 both the vanilla Enetfilter interface, and the extended interface
1880 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1882 - TFTP packets are now printed (requests only).
1884 - BOOTP packets are now printed.
1886 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1888 - Sparc architectures, including the Sparcstation-1, are now
1889 supported thanks to Steve McCanne and Craig Leres.
1891 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1892 University (micky@cunixc.cc.columbia.edu).
1894 - IP options are now printed.
1896 - RIP packets are now printed.
1898 - There's a -v flag that prints out more information than the
1899 default (e.g., it will enable printing of IP ttl, tos and id)
1900 and -q flag that prints out less (e.g., it will disable
1901 interpretation of AppleTalk-in-UDP).
1903 - The grammar has undergone substantial changes (if you have an
1904 earlier version of tcpdump, you should re-read the manual
1907 The most useful change is the addition of an expression
1908 syntax that lets you filter on arbitrary fields or values in the
1909 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1910 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1913 The most painful change is that concatenation no longer means
1914 "and" -- e.g., you have to say "host foo and port bar" instead
1915 of "host foo port bar". The up side to this down is that
1916 repeated qualifiers can be omitted, making most filter
1917 expressions shorter. E.g., you can now say "ip host foo and
1918 (bar or baz)" to look at ip traffic between hosts foo and bar or
1919 between hosts foo and baz. [The old way of saying this was "ip
1920 host foo and (ip host bar or ip host baz)".]
1922 v2.0 Sun Jan 13 12:20:40 PST 1991
1924 - Initial public release.
