1490 - Print arp hardware type in host order. Thanks to Onno van der Linden
1493 - Avoid solaris compiler warnings. Thanks to Bruce Barnett
1494 (barnett@grymoire.crd.ge.com)
1496 - Fix rip printer to not print one more route than is actually in the
1497 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
1498 Bill Fenner (fenner@parc.xerox.com)
1500 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
1502 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
1503 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1505 - Rewrite ospf printer to improve truncation checks.
1507 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1508 (davids@secnet.com). Also, check tcp options to make sure they ar
1509 actually in the tcp header (in addition to the normal truncation
1510 checks). Fix the SACK code to print the N blocks (instead of the
1511 first block N times).
1513 - Don't say really small UDP packets are truncated just because they
1514 aren't big enough to be a RPC. As noted by David Sacerdote.

1542 Thanks to John Hawkinson.
1544 - Added some more packet truncation checks.

1620 define being referenced. Reported by Terry Kennedy.
1622 - Minor fixes to the man page thanks to Mark Andrews.
1624 - Endian fixes to RTP and vat packet dumpers, thanks to Bruce Mah

1656 selective acknowledgment case.
1658 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig

1662 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1665 - Don't checksum ip header if we don't have all of it. Thanks to John
1666 Hawkinson (jhawk@mit.edu).
1668 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1669 Honig (jhc@bsdi.com)
1672 v3.1a1 Wed May 3 19:21:11 PDT 1995
1674 - Include time.h when SVR4 is defined to avoid problems under Solaris
1677 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1678 strings, not the local buffer. Thanks to Stefan Petri
1679 (petri@ibr.cs.tu-bs.de).
1681 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1682 that the selected value was not used. Thanks to Pascal Hennequin
1683 (Pascal.Hennequin@hugo.int-evry.fr).
1685 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1687 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1689 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1691 - Although there never was a 3.0.3 release, the linux boys cleverly
1692 "released" one in late 1995.
1694 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1696 - Change configuration to not use gcc v2 flags with gcc v1.
1698 - Redo gmt2local() so that it works under BSDI (which seems to return
1699 an empty timezone struct from gettimeofday()). Based on report from
1700 Terry Kennedy (terry@spcvxa.spc.edu).
1702 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1703 on report from Mark Andrews (mandrews@alias.com).
1705 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1706 Orth (ro@techfak.uni-bielefeld.de).
1708 - Fixed printout of connection id for uncompressed tcp slip packets.
1709 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1711 - Hack around deficiency in Ultrix's make.
1713 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1715 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1717 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1719 v3.0 Mon Jun 20 19:23:27 PDT 1994
1721 - Added support for printing tcp option timestamps thanks to
1722 Mark Andrews (mandrews@alias.com).
1724 - Reorganize protocol dumpers to take const pointers to packets so they
1725 never change the contents (i.e., they used to do endian conversions
1726 in place). Previously, whenever more than one pass was taken over
1727 the packet, the packet contents would be dumped incorrectly (i.e.,
1728 the output form -x would be wrong on little endian machines because
1729 the protocol dumpers would modify the data). Thanks to Charles Hannum
1730 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1732 - Added support for decnet protocol dumping thanks to Jeff Mogul
1735 - Fix bug that caused length of packet to be incorrectly printed
1736 (off by ether header size) for unknown ethernet types thanks
1737 to Greg Miller (gmiller@kayak.mitre.org).
1739 - Added support for IPX protocol dumping thanks to Brad Parker
1742 - Added check to verify IP header checksum under -v thanks to
1743 Brad Parker (brad@fcr.com).
1745 - Move packet capture code to new libpcap library (which is
1746 packaged separately).
1748 - Prototype everything and assume an ansi compiler.
1750 - print-arp.c: Print hardware ethernet addresses if they're not
1753 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1754 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1756 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1759 - print-icmp.c: Byte swap netmask before printing. Thanks to
1760 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1762 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1763 By default, only the inner packet is dumped, appended with the token
1764 "(encap)". Under -v, both the inner and output packets are dumped
1765 (on the same line). Note that the filter applies to the original packet,
1766 not the encapsulated packet. So if you run tcpdump on a net with an
1767 IP Multicast tunnel, you cannot filter out the datagrams using the
1768 conventional syntax. (You can filter away all the ip-in-ip traffic
1769 with "not ip proto 4".)
1771 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1772 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1774 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1776 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1777 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1778 Add && and || operators
1780 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1782 - Fix bug with -c flag.
1784 v2.2 Fri May 22 17:19:41 PDT 1992
1786 - savefile.c: Remove hack that shouldn't have been exported. Add
1789 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1790 matches non-echo/reply ICMP packets.
1792 - Many improvements to filter code optimizer.
1794 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1795 so that protocol qualifications are allowed. For example, "ip broadcast"
1796 and "ether multicast" are valid filters.
1798 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1799 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1800 patches to netinet/if_loop.c.
1802 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1803 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1805 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1807 v2.1 Tue Jan 28 11:00:14 PST 1992
1809 - Internal release (never publicly exported).
1811 v2.0.1 Sun Jan 26 21:10:10 PDT
1813 - Various byte ordering fixes.
1815 - Add truncation checks.
1817 - inet.c: Support BSD style SIOCGIFCONF.
1819 - nametoaddr.c: Handle multi addresses for single host.
1821 - optimize.c: Rewritten.
1823 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1826 - print-atal.c: Fix an alignment bug (thanks to
1827 stanonik@nprdc.navy.mil) Add missing printf() argument.
1829 - print-bootp.c: First attempt at decoding the vendor buffer.
1831 - print-domain.c: Fix truncation checks.
1833 - print-icmp.c: Calculate length of packets from the ip header.
1835 - print-ip.c: Print frag id in decimal (so it's easier to match up
1836 with non-frags). Add support for ospf, egp and igmp.
1838 - print-nfs.c: Lots of changes.
1840 - print-ntp.c: Make some verbose output depend on -v.
1842 - print-snmp.c: New version from John LoVerso.
1844 - print-tcp.c: Print rfc1072 tcp options.
1846 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1847 (microseconds) worth of precision. Fix uid bugs.
1849 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1850 With this option, you can create an architecture independent binary
1851 trace file in real time, without the overhead of the packet printer.
1852 At a later time, the packets can be filtered (again) and printed.
1854 - BSD is supported. You must have BPF in your kernel.
1855 Since the filtering is now done in the kernel, fewer packets are
1856 dropped. In fact, with BPF and the packet dumper option, a measly
1857 Sun 3/50 can keep up with a busy network.
1859 - Compressed SLIP packets can now be dumped, provided you use our
1860 SLIP software and BPF. These packets are dumped as any other IP
1861 packet; the compressed headers are dumped with the '-e' option.
1863 - Machines with little-endian byte ordering are supported (thanks to
1866 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1868 - IBM RT and Stanford Enetfilter support has been added by
1869 Rayan Zachariassen <rayan@canet.ca>. tcpdump has been tested under
1870 both the vanilla Enetfilter interface, and the extended interface
1871 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1873 - TFTP packets are now printed (requests only).
1875 - BOOTP packets are now printed.
1877 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1879 - Sparc architectures, including the Sparcstation-1, are now
1880 supported thanks to Steve McCanne and Craig Leres.
1882 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1883 University (micky@cunixc.cc.columbia.edu).
1885 - IP options are now printed.
1887 - RIP packets are now printed.
1889 - There's a -v flag that prints out more information than the
1890 default (e.g., it will enable printing of IP ttl, tos and id)
1891 and -q flag that prints out less (e.g., it will disable
1892 interpretation of AppleTalk-in-UDP).
1894 - The grammar has undergone substantial changes (if you have an
1895 earlier version of tcpdump, you should re-read the manual
1898 The most useful change is the addition of an expression
1899 syntax that lets you filter on arbitrary fields or values in the
1900 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1901 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1904 The most painful change is that concatenation no longer means
1905 "and" -- e.g., you have to say "host foo and port bar" instead
1906 of "host foo port bar". The up side to this down is that
1907 repeated qualifiers can be omitted, making most filter
1908 expressions shorter. E.g., you can now say "ip host foo and
1909 (bar or baz)" to look at ip traffic between hosts foo and bar or
1910 between hosts foo and baz. [The old way of saying this was "ip
1911 host foo and (ip host bar or ip host baz)".]
1913 v2.0 Sun Jan 13 12:20:40 PST 1991
1915 - Initial public release.
