1477 checks). Fix the SACK code to print the N blocks (instead of the
1478 first block N times).
1480 - Don't say really small UDP packets are truncated just because they
1481 aren't big enough to be a RPC. As noted by David Sacerdote.

1652 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1654 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1656 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1658 - Although there never was a 3.0.3 release, the linux boys cleverly
1659 "released" one in late 1995.
1661 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1663 - Change configuration to not use gcc v2 flags with gcc v1.
1665 - Redo gmt2local() so that it works under BSDI (which seems to return
1666 an empty timezone struct from gettimeofday()). Based on report from
1667 Terry Kennedy (terry@spcvxa.spc.edu).
1669 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1670 on report from Mark Andrews (mandrews@alias.com).
1672 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1673 Orth (ro@techfak.uni-bielefeld.de).
1675 - Fixed printout of connection id for uncompressed tcp slip packets.
1676 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1678 - Hack around deficiency in Ultrix's make.

1682 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1684 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1686 v3.0 Mon Jun 20 19:23:27 PDT 1994
1688 - Added support for printing tcp option timestamps thanks to
1689 Mark Andrews (mandrews@alias.com).
1691 - Reorganize protocol dumpers to take const pointers to packets so they
1692 never change the contents (i.e., they used to do endian conversions
1693 in place). Previously, whenever more than one pass was taken over
1694 the packet, the packet contents would be dumped incorrectly (i.e.,
1695 the output form -x would be wrong on little endian machines because
1696 the protocol dumpers would modify the data). Thanks to Charles Hannum
1697 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1699 - Added support for decnet protocol dumping thanks to Jeff Mogul
1702 - Fix bug that caused length of packet to be incorrectly printed
1703 (off by ether header size) for unknown ethernet types thanks
1704 to Greg Miller (gmiller@kayak.mitre.org).
1706 - Added support for IPX protocol dumping thanks to Brad Parker
1709 - Added check to verify IP header checksum under -v thanks to
1710 Brad Parker (brad@fcr.com).
1712 - Move packet capture code to new libpcap library (which is
1713 packaged separately).
1715 - Prototype everything and assume an ansi compiler.
1717 - print-arp.c: Print hardware ethernet addresses if they're not
1720 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1721 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1723 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1726 - print-icmp.c: Byte swap netmask before printing. Thanks to
1727 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1729 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1730 By default, only the inner packet is dumped, appended with the token
1731 "(encap)". Under -v, both the inner and output packets are dumped
1732 (on the same line). Note that the filter applies to the original packet,
1733 not the encapsulated packet. So if you run tcpdump on a net with an
1734 IP Multicast tunnel, you cannot filter out the datagrams using the
1735 conventional syntax. (You can filter away all the ip-in-ip traffic
1736 with "not ip proto 4".)
1738 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1739 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1741 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1743 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1744 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1745 Add && and || operators
1747 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1749 - Fix bug with -c flag.
1751 v2.2 Fri May 22 17:19:41 PDT 1992
1753 - savefile.c: Remove hack that shouldn't have been exported. Add
1756 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1757 matches non-echo/reply ICMP packets.
1759 - Many improvements to filter code optimizer.
1761 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1762 so that protocol qualifications are allowed. For example, "ip broadcast"
1763 and "ether multicast" are valid filters.
1765 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1766 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1767 patches to netinet/if_loop.c.
1769 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1770 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1772 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1774 v2.1 Tue Jan 28 11:00:14 PST 1992
1776 - Internal release (never publicly exported).
1778 v2.0.1 Sun Jan 26 21:10:10 PDT
1780 - Various byte ordering fixes.
1782 - Add truncation checks.
1784 - inet.c: Support BSD style SIOCGIFCONF.
1786 - nametoaddr.c: Handle multi addresses for single host.
1788 - optimize.c: Rewritten.
1790 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1793 - print-atal.c: Fix an alignment bug (thanks to
1794 stanonik@nprdc.navy.mil) Add missing printf() argument.
1796 - print-bootp.c: First attempt at decoding the vendor buffer.
1798 - print-domain.c: Fix truncation checks.
1800 - print-icmp.c: Calculate length of packets from the ip header.
1802 - print-ip.c: Print frag id in decimal (so it's easier to match up
1803 with non-frags). Add support for ospf, egp and igmp.
1805 - print-nfs.c: Lots of changes.
1807 - print-ntp.c: Make some verbose output depend on -v.
1809 - print-snmp.c: New version from John LoVerso.
1811 - print-tcp.c: Print rfc1072 tcp options.
1813 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1814 (microseconds) worth of precision. Fix uid bugs.
1816 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1817 With this option, you can create an architecture independent binary
1818 trace file in real time, without the overhead of the packet printer.
1819 At a later time, the packets can be filtered (again) and printed.
1821 - BSD is supported. You must have BPF in your kernel.
1822 Since the filtering is now done in the kernel, fewer packets are
1823 dropped. In fact, with BPF and the packet dumper option, a measly
1824 Sun 3/50 can keep up with a busy network.
1826 - Compressed SLIP packets can now be dumped, provided you use our
1827 SLIP software and BPF. These packets are dumped as any other IP
1828 packet; the compressed headers are dumped with the '-e' option.
1830 - Machines with little-endian byte ordering are supported (thanks to
1833 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1835 - IBM RT and Stanford Enetfilter support has been added by
1836 Rayan Zachariassen <rayan@canet.ca>. tcpdump has been tested under
1837 both the vanilla Enetfilter interface, and the extended interface
1838 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1840 - TFTP packets are now printed (requests only).
1842 - BOOTP packets are now printed.
1844 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1846 - Sparc architectures, including the Sparcstation-1, are now
1847 supported thanks to Steve McCanne and Craig Leres.
1849 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1850 University (micky@cunixc.cc.columbia.edu).
1852 - IP options are now printed.
1854 - RIP packets are now printed.
1856 - There's a -v flag that prints out more information than the
1857 default (e.g., it will enable printing of IP ttl, tos and id)
1858 and -q flag that prints out less (e.g., it will disable
1859 interpretation of AppleTalk-in-UDP).
1861 - The grammar has undergone substantial changes (if you have an
1862 earlier version of tcpdump, you should re-read the manual
1865 The most useful change is the addition of an expression
1866 syntax that lets you filter on arbitrary fields or values in the
1867 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1868 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1871 The most painful change is that concatenation no longer means
1872 "and" -- e.g., you have to say "host foo and port bar" instead
1873 of "host foo port bar". The up side to this down is that
1874 repeated qualifiers can be omitted, making most filter
1875 expressions shorter. E.g., you can now say "ip host foo and
1876 (bar or baz)" to look at ip traffic between hosts foo and bar or
1877 between hosts foo and baz. [The old way of saying this was "ip
1878 host foo and (ip host bar or ip host baz)".]
1880 v2.0 Sun Jan 13 12:20:40 PST 1991
1882 - Initial public release.
