1495 (barnett@grymoire.crd.ge.com)
1497 - Fix rip printer to not print one more route than is actually in the
1498 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
1499 Bill Fenner (fenner@parc.xerox.com)
1501 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
1503 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
1504 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1506 - Rewrite ospf printer to improve truncation checks.
1508 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1509 (davids@secnet.com). Also, check tcp options to make sure they ar
1510 actually in the tcp header (in addition to the normal truncation
1511 checks). Fix the SACK code to print the N blocks (instead of the
1512 first block N times).
1514 - Don't say really small UDP packets are truncated just because they
1515 aren't big enough to be a RPC. As noted by David Sacerdote.

1621 define being referenced. Reported by Terry Kennedy.
1623 - Minor fixes to the man page thanks to Mark Andrews.
1625 - Endian fixes to RTP and vat packet dumpers, thanks to Bruce Mah

1657 selective acknowledgment case.
1659 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
1662 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
1663 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1666 - Don't checksum ip header if we don't have all of it. Thanks to John
1667 Hawkinson (jhawk@mit.edu).
1669 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1670 Honig (jhc@bsdi.com)
1673 v3.1a1 Wed May 3 19:21:11 PDT 1995
1675 - Include time.h when SVR4 is defined to avoid problems under Solaris
1678 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1679 strings, not the local buffer. Thanks to Stefan Petri
1680 (petri@ibr.cs.tu-bs.de).
1682 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1683 that the selected value was not used. Thanks to Pascal Hennequin
1684 (Pascal.Hennequin@hugo.int-evry.fr).
1686 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1688 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1690 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1692 - Although there never was a 3.0.3 release, the linux boys cleverly
1693 "released" one in late 1995.
1695 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1697 - Change configuration to not use gcc v2 flags with gcc v1.
1699 - Redo gmt2local() so that it works under BSDI (which seems to return
1700 an empty timezone struct from gettimeofday()). Based on report from
1701 Terry Kennedy (terry@spcvxa.spc.edu).
1703 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1704 on report from Mark Andrews (mandrews@alias.com).
1706 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1707 Orth (ro@techfak.uni-bielefeld.de).
1709 - Fixed printout of connection id for uncompressed tcp slip packets.
1710 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1712 - Hack around deficiency in Ultrix's make.
1714 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1716 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1718 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1720 v3.0 Mon Jun 20 19:23:27 PDT 1994
1722 - Added support for printing tcp option timestamps thanks to
1723 Mark Andrews (mandrews@alias.com).
1725 - Reorganize protocol dumpers to take const pointers to packets so they
1726 never change the contents (i.e., they used to do endian conversions
1727 in place). Previously, whenever more than one pass was taken over
1728 the packet, the packet contents would be dumped incorrectly (i.e.,
1729 the output form -x would be wrong on little endian machines because
1730 the protocol dumpers would modify the data). Thanks to Charles Hannum
1731 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1733 - Added support for decnet protocol dumping thanks to Jeff Mogul
1736 - Fix bug that caused length of packet to be incorrectly printed
1737 (off by ether header size) for unknown ethernet types thanks
1738 to Greg Miller (gmiller@kayak.mitre.org).
1740 - Added support for IPX protocol dumping thanks to Brad Parker
1743 - Added check to verify IP header checksum under -v thanks to
1744 Brad Parker (brad@fcr.com).
1746 - Move packet capture code to new libpcap library (which is
1747 packaged separately).
1749 - Prototype everything and assume an ansi compiler.
1751 - print-arp.c: Print hardware ethernet addresses if they're not
1754 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1755 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1757 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1760 - print-icmp.c: Byte swap netmask before printing. Thanks to
1761 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1763 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1764 By default, only the inner packet is dumped, appended with the token
1765 "(encap)". Under -v, both the inner and output packets are dumped
1766 (on the same line). Note that the filter applies to the original packet,
1767 not the encapsulated packet. So if you run tcpdump on a net with an
1768 IP Multicast tunnel, you cannot filter out the datagrams using the
1769 conventional syntax. (You can filter away all the ip-in-ip traffic
1770 with "not ip proto 4".)
1772 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1773 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1775 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1777 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1778 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1779 Add && and || operators
1781 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1783 - Fix bug with -c flag.
1785 v2.2 Fri May 22 17:19:41 PDT 1992
1787 - savefile.c: Remove hack that shouldn't have been exported. Add
1790 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1791 matches non-echo/reply ICMP packets.
1793 - Many improvements to filter code optimizer.
1795 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1796 so that protocol qualifications are allowed. For example, "ip broadcast"
1797 and "ether multicast" are valid filters.
1799 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1800 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1801 patches to netinet/if_loop.c.
1803 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1804 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1806 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1808 v2.1 Tue Jan 28 11:00:14 PST 1992
1810 - Internal release (never publicly exported).
1812 v2.0.1 Sun Jan 26 21:10:10 PDT
1814 - Various byte ordering fixes.
1816 - Add truncation checks.
1818 - inet.c: Support BSD style SIOCGIFCONF.
1820 - nametoaddr.c: Handle multi addresses for single host.
1822 - optimize.c: Rewritten.
1824 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1827 - print-atal.c: Fix an alignment bug (thanks to
1828 stanonik@nprdc.navy.mil) Add missing printf() argument.
1830 - print-bootp.c: First attempt at decoding the vendor buffer.
1832 - print-domain.c: Fix truncation checks.
1834 - print-icmp.c: Calculate length of packets from the ip header.
1836 - print-ip.c: Print frag id in decimal (so it's easier to match up
1837 with non-frags). Add support for ospf, egp and igmp.
1839 - print-nfs.c: Lots of changes.
1841 - print-ntp.c: Make some verbose output depend on -v.
1843 - print-snmp.c: New version from John LoVerso.
1845 - print-tcp.c: Print rfc1072 tcp options.
1847 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1848 (microseconds) worth of precision. Fix uid bugs.
1850 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1851 With this option, you can create an architecture independent binary
1852 trace file in real time, without the overhead of the packet printer.
1853 At a later time, the packets can be filtered (again) and printed.
1855 - BSD is supported. You must have BPF in your kernel.
1856 Since the filtering is now done in the kernel, fewer packets are
1857 dropped. In fact, with BPF and the packet dumper option, a measly
1858 Sun 3/50 can keep up with a busy network.
1860 - Compressed SLIP packets can now be dumped, provided you use our
1861 SLIP software and BPF. These packets are dumped as any other IP
1862 packet; the compressed headers are dumped with the '-e' option.
1864 - Machines with little-endian byte ordering are supported (thanks to
1867 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1869 - IBM RT and Stanford Enetfilter support has been added by
1870 Rayan Zachariassen <rayan@canet.ca>. tcpdump has been tested under
1871 both the vanilla Enetfilter interface, and the extended interface
1872 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1874 - TFTP packets are now printed (requests only).
1876 - BOOTP packets are now printed.
1878 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1880 - Sparc architectures, including the Sparcstation-1, are now
1881 supported thanks to Steve McCanne and Craig Leres.
1883 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1884 University (micky@cunixc.cc.columbia.edu).
1886 - IP options are now printed.
1888 - RIP packets are now printed.
1890 - There's a -v flag that prints out more information than the
1891 default (e.g., it will enable printing of IP ttl, tos and id)
1892 and -q flag that prints out less (e.g., it will disable
1893 interpretation of AppleTalk-in-UDP).
1895 - The grammar has undergone substantial changes (if you have an
1896 earlier version of tcpdump, you should re-read the manual
1899 The most useful change is the addition of an expression
1900 syntax that lets you filter on arbitrary fields or values in the
1901 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1902 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1905 The most painful change is that concatenation no longer means
1906 "and" -- e.g., you have to say "host foo and port bar" instead
1907 of "host foo port bar". The up side to this down is that
1908 repeated qualifiers can be omitted, making most filter
1909 expressions shorter. E.g., you can now say "ip host foo and
1910 (bar or baz)" to look at ip traffic between hosts foo and bar or
1911 between hosts foo and baz. [The old way of saying this was "ip
1912 host foo and (ip host bar or ip host baz)".]
1914 v2.0 Sun Jan 13 12:20:40 PST 1991
1916 - Initial public release.
