1480 checks). Fix the SACK code to print the N blocks (instead of the
1481 first block N times).
1483 - Don't say really small UDP packets are truncated just because they

1655 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1657 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1659 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1661 - Although there never was a 3.0.3 release, the linux boys cleverly
1662 "released" one in late 1995.
1664 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1666 - Change configuration to not use gcc v2 flags with gcc v1.
1668 - Redo gmt2local() so that it works under BSDI (which seems to return
1669 an empty timezone struct from gettimeofday()). Based on report from
1670 Terry Kennedy (terry@spcvxa.spc.edu).
1672 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1673 on report from Mark Andrews (mandrews@alias.com).
1675 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1676 Orth (ro@techfak.uni-bielefeld.de).
1678 - Fixed printout of connection id for uncompressed tcp slip packets.

1685 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1687 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1689 v3.0 Mon Jun 20 19:23:27 PDT 1994
1691 - Added support for printing tcp option timestamps thanks to
1692 Mark Andrews (mandrews@alias.com).
1694 - Reorganize protocol dumpers to take const pointers to packets so they
1695 never change the contents (i.e., they used to do endian conversions
1696 in place). Previously, whenever more than one pass was taken over
1697 the packet, the packet contents would be dumped incorrectly (i.e.,
1698 the output form -x would be wrong on little endian machines because
1699 the protocol dumpers would modify the data). Thanks to Charles Hannum
1700 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1702 - Added support for decnet protocol dumping thanks to Jeff Mogul
1705 - Fix bug that caused length of packet to be incorrectly printed
1706 (off by ether header size) for unknown ethernet types thanks
1707 to Greg Miller (gmiller@kayak.mitre.org).
1709 - Added support for IPX protocol dumping thanks to Brad Parker
1712 - Added check to verify IP header checksum under -v thanks to
1713 Brad Parker (brad@fcr.com).
1715 - Move packet capture code to new libpcap library (which is
1716 packaged separately).
1718 - Prototype everything and assume an ansi compiler.
1720 - print-arp.c: Print hardware ethernet addresses if they're not
1723 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1724 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1726 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1729 - print-icmp.c: Byte swap netmask before printing. Thanks to
1730 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1732 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1733 By default, only the inner packet is dumped, appended with the token
1734 "(encap)". Under -v, both the inner and output packets are dumped
1735 (on the same line). Note that the filter applies to the original packet,
1736 not the encapsulated packet. So if you run tcpdump on a net with an
1737 IP Multicast tunnel, you cannot filter out the datagrams using the
1738 conventional syntax. (You can filter away all the ip-in-ip traffic
1739 with "not ip proto 4".)
1741 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1742 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1744 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1746 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1747 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1748 Add && and || operators
1750 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1752 - Fix bug with -c flag.
1754 v2.2 Fri May 22 17:19:41 PDT 1992
1756 - savefile.c: Remove hack that shouldn't have been exported. Add
1759 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1760 matches non-echo/reply ICMP packets.
1762 - Many improvements to filter code optimizer.
1764 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1765 so that protocol qualifications are allowed. For example, "ip broadcast"
1766 and "ether multicast" are valid filters.
1768 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1769 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1770 patches to netinet/if_loop.c.
1772 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1773 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1775 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1777 v2.1 Tue Jan 28 11:00:14 PST 1992
1779 - Internal release (never publicly exported).
1781 v2.0.1 Sun Jan 26 21:10:10 PDT
1783 - Various byte ordering fixes.
1785 - Add truncation checks.
1787 - inet.c: Support BSD style SIOCGIFCONF.
1789 - nametoaddr.c: Handle multi addresses for single host.
1791 - optimize.c: Rewritten.
1793 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1796 - print-atal.c: Fix an alignment bug (thanks to
1797 stanonik@nprdc.navy.mil) Add missing printf() argument.
1799 - print-bootp.c: First attempt at decoding the vendor buffer.
1801 - print-domain.c: Fix truncation checks.
1803 - print-icmp.c: Calculate length of packets from the ip header.
1805 - print-ip.c: Print frag id in decimal (so it's easier to match up
1806 with non-frags). Add support for ospf, egp and igmp.
1808 - print-nfs.c: Lots of changes.
1810 - print-ntp.c: Make some verbose output depend on -v.
1812 - print-snmp.c: New version from John LoVerso.
1814 - print-tcp.c: Print rfc1072 tcp options.
1816 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1817 (microseconds) worth of precision. Fix uid bugs.
1819 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1820 With this option, you can create an architecture independent binary
1821 trace file in real time, without the overhead of the packet printer.
1822 At a later time, the packets can be filtered (again) and printed.
1824 - BSD is supported. You must have BPF in your kernel.
1825 Since the filtering is now done in the kernel, fewer packets are
1826 dropped. In fact, with BPF and the packet dumper option, a measly
1827 Sun 3/50 can keep up with a busy network.
1829 - Compressed SLIP packets can now be dumped, provided you use our
1830 SLIP software and BPF. These packets are dumped as any other IP
1831 packet; the compressed headers are dumped with the '-e' option.
1833 - Machines with little-endian byte ordering are supported (thanks to
1836 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1838 - IBM RT and Stanford Enetfilter support has been added by
1839 Rayan Zachariassen <rayan@canet.ca>. tcpdump has been tested under
1840 both the vanilla Enetfilter interface, and the extended interface
1841 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1843 - TFTP packets are now printed (requests only).
1845 - BOOTP packets are now printed.
1847 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1849 - Sparc architectures, including the Sparcstation-1, are now
1850 supported thanks to Steve McCanne and Craig Leres.
1852 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1853 University (micky@cunixc.cc.columbia.edu).
1855 - IP options are now printed.
1857 - RIP packets are now printed.
1859 - There's a -v flag that prints out more information than the
1860 default (e.g., it will enable printing of IP ttl, tos and id)
1861 and -q flag that prints out less (e.g., it will disable
1862 interpretation of AppleTalk-in-UDP).
1864 - The grammar has undergone substantial changes (if you have an
1865 earlier version of tcpdump, you should re-read the manual
1868 The most useful change is the addition of an expression
1869 syntax that lets you filter on arbitrary fields or values in the
1870 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1871 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1874 The most painful change is that concatenation no longer means
1875 "and" -- e.g., you have to say "host foo and port bar" instead
1876 of "host foo port bar". The up side to this down is that
1877 repeated qualifiers can be omitted, making most filter
1878 expressions shorter. E.g., you can now say "ip host foo and
1879 (bar or baz)" to look at ip traffic between hosts foo and bar or
1880 between hosts foo and baz. [The old way of saying this was "ip
1881 host foo and (ip host bar or ip host baz)".]
1883 v2.0 Sun Jan 13 12:20:40 PST 1991
1885 - Initial public release.
