1378 first block N times).
1380 - Don't say really small UDP packets are truncated just because they
1381 aren't big enough to be a RPC. As noted by David Sacerdote.

1548 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1549 that the selected value was not used. Thanks to Pascal Hennequin
1550 (Pascal.Hennequin@hugo.int-evry.fr).
1552 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1554 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1556 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1558 - Although there never was a 3.0.3 release, the linux boys cleverly
1559 "released" one in late 1995.
1561 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1563 - Change configuration to not use gcc v2 flags with gcc v1.
1565 - Redo gmt2local() so that it works under BSDI (which seems to return
1566 an empty timezone struct from gettimeofday()). Based on report from
1567 Terry Kennedy (terry@spcvxa.spc.edu).
1569 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1570 on report from Mark Andrews (mandrews@alias.com).
1572 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1573 Orth (ro@techfak.uni-bielefeld.de).
1575 - Fixed printout of connection id for uncompressed tcp slip packets.
1576 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1578 - Hack around deficiency in Ultrix's make.
1580 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1582 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1584 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1586 v3.0 Mon Jun 20 19:23:27 PDT 1994
1588 - Added support for printing tcp option timestamps thanks to
1589 Mark Andrews (mandrews@alias.com).
1591 - Reorganize protocol dumpers to take const pointers to packets so they
1592 never change the contents (i.e., they used to do endian conversions
1593 in place). Previously, whenever more than one pass was taken over
1594 the packet, the packet contents would be dumped incorrectly (i.e.,
1595 the output form -x would be wrong on little endian machines because
1596 the protocol dumpers would modify the data). Thanks to Charles Hannum
1597 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1599 - Added support for decnet protocol dumping thanks to Jeff Mogul
1602 - Fix bug that caused length of packet to be incorrectly printed
1603 (off by ether header size) for unknown ethernet types thanks
1604 to Greg Miller (gmiller@kayak.mitre.org).
1606 - Added support for IPX protocol dumping thanks to Brad Parker
1609 - Added check to verify IP header checksum under -v thanks to
1610 Brad Parker (brad@fcr.com).
1612 - Move packet capture code to new libpcap library (which is
1613 packaged separately).
1615 - Prototype everything and assume an ansi compiler.
1617 - print-arp.c: Print hardware ethernet addresses if they're not
1620 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1621 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1623 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1626 - print-icmp.c: Byte swap netmask before printing. Thanks to
1627 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1629 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1630 By default, only the inner packet is dumped, appended with the token
1631 "(encap)". Under -v, both the inner and output packets are dumped
1632 (on the same line). Note that the filter applies to the original packet,
1633 not the encapsulated packet. So if you run tcpdump on a net with an
1634 IP Multicast tunnel, you cannot filter out the datagrams using the
1635 conventional syntax. (You can filter away all the ip-in-ip traffic
1636 with "not ip proto 4".)
1638 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1639 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1641 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1643 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1644 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1645 Add && and || operators
1647 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1649 - Fix bug with -c flag.
1651 v2.2 Fri May 22 17:19:41 PDT 1992
1653 - savefile.c: Remove hack that shouldn't have been exported. Add
1656 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1657 matches non-echo/reply ICMP packets.
1659 - Many improvements to filter code optimizer.
1661 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1662 so that protocol qualifications are allowed. For example, "ip broadcast"
1663 and "ether multicast" are valid filters.
1665 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1666 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1667 patches to netinet/if_loop.c.
1669 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1670 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1672 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1674 v2.1 Tue Jan 28 11:00:14 PST 1992
1676 - Internal release (never publicly exported).
1678 v2.0.1 Sun Jan 26 21:10:10 PDT
1680 - Various byte ordering fixes.
1682 - Add truncation checks.
1684 - inet.c: Support BSD style SIOCGIFCONF.
1686 - nametoaddr.c: Handle multi addresses for single host.
1688 - optimize.c: Rewritten.
1690 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1693 - print-atal.c: Fix an alignment bug (thanks to
1694 stanonik@nprdc.navy.mil) Add missing printf() argument.
1696 - print-bootp.c: First attempt at decoding the vendor buffer.
1698 - print-domain.c: Fix truncation checks.
1700 - print-icmp.c: Calculate length of packets from the ip header.
1702 - print-ip.c: Print frag id in decimal (so it's easier to match up
1703 with non-frags). Add support for ospf, egp and igmp.
1705 - print-nfs.c: Lots of changes.
1707 - print-ntp.c: Make some verbose output depend on -v.
1709 - print-snmp.c: New version from John LoVerso.
1711 - print-tcp.c: Print rfc1072 tcp options.
1713 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1714 (microseconds) worth of precision. Fix uid bugs.
1716 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1717 With this option, you can create an architecture independent binary
1718 trace file in real time, without the overhead of the packet printer.
1719 At a later time, the packets can be filtered (again) and printed.
1721 - BSD is supported. You must have BPF in your kernel.
1722 Since the filtering is now done in the kernel, fewer packets are
1723 dropped. In fact, with BPF and the packet dumper option, a measly
1724 Sun 3/50 can keep up with a busy network.
1726 - Compressed SLIP packets can now be dumped, provided you use our
1727 SLIP software and BPF. These packets are dumped as any other IP
1728 packet; the compressed headers are dumped with the '-e' option.
1730 - Machines with little-endian byte ordering are supported (thanks to
1733 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1735 - IBM RT and Stanford Enetfilter support has been added by
1736 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1737 both the vanilla Enetfilter interface, and the extended interface
1738 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1740 - TFTP packets are now printed (requests only).
1742 - BOOTP packets are now printed.
1744 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1746 - Sparc architectures, including the Sparcstation-1, are now
1747 supported thanks to Steve McCanne and Craig Leres.
1749 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1750 University (micky@cunixc.cc.columbia.edu).
1752 - IP options are now printed.
1754 - RIP packets are now printed.
1756 - There's a -v flag that prints out more information than the
1757 default (e.g., it will enable printing of IP ttl, tos and id)
1758 and -q flag that prints out less (e.g., it will disable
1759 interpretation of AppleTalk-in-UDP).
1761 - The grammar has undergone substantial changes (if you have an
1762 earlier version of tcpdump, you should re-read the manual
1765 The most useful change is the addition of an expression
1766 syntax that lets you filter on arbitrary fields or values in the
1767 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1768 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1771 The most painful change is that concatenation no longer means
1772 "and" -- e.g., you have to say "host foo and port bar" instead
1773 of "host foo port bar". The up side to this down is that
1774 repeated qualifiers can be omitted, making most filter
1775 expressions shorter. E.g., you can now say "ip host foo and
1776 (bar or baz)" to look at ip traffic between hosts foo and bar or
1777 between hosts foo and baz. [The old way of saying this was "ip
1778 host foo and (ip host bar or ip host baz)".]
1780 v2.0 Sun Jan 13 12:20:40 PST 1991
1782 - Initial public release.
