1371 checks). Fix the SACK code to print the N blocks (instead of the
1372 first block N times).
1374 - Don't say really small UDP packets are truncated just because they
1375 aren't big enough to be a RPC. As noted by David Sacerdote.

1546 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1548 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1550 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1552 - Although there never was a 3.0.3 release, the linux boys cleverly
1553 "released" one in late 1995.
1555 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1557 - Change configuration to not use gcc v2 flags with gcc v1.
1559 - Redo gmt2local() so that it works under BSDI (which seems to return
1560 an empty timezone struct from gettimeofday()). Based on report from
1561 Terry Kennedy (terry@spcvxa.spc.edu).
1563 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1564 on report from Mark Andrews (mandrews@alias.com).
1566 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1567 Orth (ro@techfak.uni-bielefeld.de).
1569 - Fixed printout of connection id for uncompressed tcp slip packets.
1570 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1572 - Hack around deficiency in Ultrix's make.
1574 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1576 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1578 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1580 v3.0 Mon Jun 20 19:23:27 PDT 1994
1582 - Added support for printing tcp option timestamps thanks to
1583 Mark Andrews (mandrews@alias.com).
1585 - Reorganize protocol dumpers to take const pointers to packets so they
1586 never change the contents (i.e., they used to do endian conversions
1587 in place). Previously, whenever more than one pass was taken over
1588 the packet, the packet contents would be dumped incorrectly (i.e.,
1589 the output form -x would be wrong on little endian machines because
1590 the protocol dumpers would modify the data). Thanks to Charles Hannum
1591 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1593 - Added support for decnet protocol dumping thanks to Jeff Mogul
1596 - Fix bug that caused length of packet to be incorrectly printed
1597 (off by ether header size) for unknown ethernet types thanks
1598 to Greg Miller (gmiller@kayak.mitre.org).
1600 - Added support for IPX protocol dumping thanks to Brad Parker
1603 - Added check to verify IP header checksum under -v thanks to
1604 Brad Parker (brad@fcr.com).
1606 - Move packet capture code to new libpcap library (which is
1607 packaged separately).
1609 - Prototype everything and assume an ansi compiler.
1611 - print-arp.c: Print hardware ethernet addresses if they're not
1614 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1615 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1617 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1620 - print-icmp.c: Byte swap netmask before printing. Thanks to
1621 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1623 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1624 By default, only the inner packet is dumped, appended with the token
1625 "(encap)". Under -v, both the inner and output packets are dumped
1626 (on the same line). Note that the filter applies to the original packet,
1627 not the encapsulated packet. So if you run tcpdump on a net with an
1628 IP Multicast tunnel, you cannot filter out the datagrams using the
1629 conventional syntax. (You can filter away all the ip-in-ip traffic
1630 with "not ip proto 4".)
1632 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1633 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1635 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1637 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1638 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1639 Add && and || operators
1641 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1643 - Fix bug with -c flag.
1645 v2.2 Fri May 22 17:19:41 PDT 1992
1647 - savefile.c: Remove hack that shouldn't have been exported. Add
1650 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1651 matches non-echo/reply ICMP packets.
1653 - Many improvements to filter code optimizer.
1655 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1656 so that protocol qualifications are allowed. For example, "ip broadcast"
1657 and "ether multicast" are valid filters.
1659 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1660 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1661 patches to netinet/if_loop.c.
1663 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1664 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1666 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1668 v2.1 Tue Jan 28 11:00:14 PST 1992
1670 - Internal release (never publicly exported).
1672 v2.0.1 Sun Jan 26 21:10:10 PDT
1674 - Various byte ordering fixes.
1676 - Add truncation checks.
1678 - inet.c: Support BSD style SIOCGIFCONF.
1680 - nametoaddr.c: Handle multi addresses for single host.
1682 - optimize.c: Rewritten.
1684 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1687 - print-atal.c: Fix an alignment bug (thanks to
1688 stanonik@nprdc.navy.mil) Add missing printf() argument.
1690 - print-bootp.c: First attempt at decoding the vendor buffer.
1692 - print-domain.c: Fix truncation checks.
1694 - print-icmp.c: Calculate length of packets from the ip header.
1696 - print-ip.c: Print frag id in decimal (so it's easier to match up
1697 with non-frags). Add support for ospf, egp and igmp.
1699 - print-nfs.c: Lots of changes.
1701 - print-ntp.c: Make some verbose output depend on -v.
1703 - print-snmp.c: New version from John LoVerso.
1705 - print-tcp.c: Print rfc1072 tcp options.
1707 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1708 (microseconds) worth of precision. Fix uid bugs.
1710 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1711 With this option, you can create an architecture independent binary
1712 trace file in real time, without the overhead of the packet printer.
1713 At a later time, the packets can be filtered (again) and printed.
1715 - BSD is supported. You must have BPF in your kernel.
1716 Since the filtering is now done in the kernel, fewer packets are
1717 dropped. In fact, with BPF and the packet dumper option, a measly
1718 Sun 3/50 can keep up with a busy network.
1720 - Compressed SLIP packets can now be dumped, provided you use our
1721 SLIP software and BPF. These packets are dumped as any other IP
1722 packet; the compressed headers are dumped with the '-e' option.
1724 - Machines with little-endian byte ordering are supported (thanks to
1727 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1729 - IBM RT and Stanford Enetfilter support has been added by
1730 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1731 both the vanilla Enetfilter interface, and the extended interface
1732 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1734 - TFTP packets are now printed (requests only).
1736 - BOOTP packets are now printed.
1738 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1740 - Sparc architectures, including the Sparcstation-1, are now
1741 supported thanks to Steve McCanne and Craig Leres.
1743 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1744 University (micky@cunixc.cc.columbia.edu).
1746 - IP options are now printed.
1748 - RIP packets are now printed.
1750 - There's a -v flag that prints out more information than the
1751 default (e.g., it will enable printing of IP ttl, tos and id)
1752 and -q flag that prints out less (e.g., it will disable
1753 interpretation of AppleTalk-in-UDP).
1755 - The grammar has undergone substantial changes (if you have an
1756 earlier version of tcpdump, you should re-read the manual
1759 The most useful change is the addition of an expression
1760 syntax that lets you filter on arbitrary fields or values in the
1761 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1762 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1765 The most painful change is that concatenation no longer means
1766 "and" -- e.g., you have to say "host foo and port bar" instead
1767 of "host foo port bar". The up side to this down is that
1768 repeated qualifiers can be omitted, making most filter
1769 expressions shorter. E.g., you can now say "ip host foo and
1770 (bar or baz)" to look at ip traffic between hosts foo and bar or
1771 between hosts foo and baz. [The old way of saying this was "ip
1772 host foo and (ip host bar or ip host baz)".]
1774 v2.0 Sun Jan 13 12:20:40 PST 1991
1776 - Initial public release.
