1397 first block N times).
1399 - Don't say really small UDP packets are truncated just because they
1400 aren't big enough to be a RPC. As noted by David Sacerdote.

1541 - Rewrote tcp options printer code to check for truncation. Added
1542 selective acknowledgment case.
1544 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
1547 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
1548 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1551 - Don't checksum ip header if we don't have all of it. Thanks to John
1552 Hawkinson (jhawk@mit.edu).
1554 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1555 Honig (jhc@bsdi.com)
1558 v3.1a1 Wed May 3 19:21:11 PDT 1995
1560 - Include time.h when SVR4 is defined to avoid problems under Solaris
1563 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1564 strings, not the local buffer. Thanks to Stefan Petri
1565 (petri@ibr.cs.tu-bs.de).
1567 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1568 that the selected value was not used. Thanks to Pascal Hennequin
1569 (Pascal.Hennequin@hugo.int-evry.fr).
1571 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1573 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1575 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1577 - Although there never was a 3.0.3 release, the linux boys cleverly
1578 "released" one in late 1995.
1580 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1582 - Change configuration to not use gcc v2 flags with gcc v1.
1584 - Redo gmt2local() so that it works under BSDI (which seems to return
1585 an empty timezone struct from gettimeofday()). Based on report from
1586 Terry Kennedy (terry@spcvxa.spc.edu).
1588 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1589 on report from Mark Andrews (mandrews@alias.com).
1591 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1592 Orth (ro@techfak.uni-bielefeld.de).
1594 - Fixed printout of connection id for uncompressed tcp slip packets.
1595 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1597 - Hack around deficiency in Ultrix's make.
1599 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1601 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1603 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1605 v3.0 Mon Jun 20 19:23:27 PDT 1994
1607 - Added support for printing tcp option timestamps thanks to
1608 Mark Andrews (mandrews@alias.com).
1610 - Reorganize protocol dumpers to take const pointers to packets so they
1611 never change the contents (i.e., they used to do endian conversions
1612 in place). Previously, whenever more than one pass was taken over
1613 the packet, the packet contents would be dumped incorrectly (i.e.,
1614 the output form -x would be wrong on little endian machines because
1615 the protocol dumpers would modify the data). Thanks to Charles Hannum
1616 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1618 - Added support for decnet protocol dumping thanks to Jeff Mogul
1621 - Fix bug that caused length of packet to be incorrectly printed
1622 (off by ether header size) for unknown ethernet types thanks
1623 to Greg Miller (gmiller@kayak.mitre.org).
1625 - Added support for IPX protocol dumping thanks to Brad Parker
1628 - Added check to verify IP header checksum under -v thanks to
1629 Brad Parker (brad@fcr.com).
1631 - Move packet capture code to new libpcap library (which is
1632 packaged separately).
1634 - Prototype everything and assume an ansi compiler.
1636 - print-arp.c: Print hardware ethernet addresses if they're not
1639 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1640 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1642 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1645 - print-icmp.c: Byte swap netmask before printing. Thanks to
1646 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1648 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1649 By default, only the inner packet is dumped, appended with the token
1650 "(encap)". Under -v, both the inner and output packets are dumped
1651 (on the same line). Note that the filter applies to the original packet,
1652 not the encapsulated packet. So if you run tcpdump on a net with an
1653 IP Multicast tunnel, you cannot filter out the datagrams using the
1654 conventional syntax. (You can filter away all the ip-in-ip traffic
1655 with "not ip proto 4".)
1657 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1658 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1660 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1662 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1663 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1664 Add && and || operators
1666 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1668 - Fix bug with -c flag.
1670 v2.2 Fri May 22 17:19:41 PDT 1992
1672 - savefile.c: Remove hack that shouldn't have been exported. Add
1675 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1676 matches non-echo/reply ICMP packets.
1678 - Many improvements to filter code optimizer.
1680 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1681 so that protocol qualifications are allowed. For example, "ip broadcast"
1682 and "ether multicast" are valid filters.
1684 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1685 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1686 patches to netinet/if_loop.c.
1688 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1689 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1691 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1693 v2.1 Tue Jan 28 11:00:14 PST 1992
1695 - Internal release (never publicly exported).
1697 v2.0.1 Sun Jan 26 21:10:10 PDT
1699 - Various byte ordering fixes.
1701 - Add truncation checks.
1703 - inet.c: Support BSD style SIOCGIFCONF.
1705 - nametoaddr.c: Handle multi addresses for single host.
1707 - optimize.c: Rewritten.
1709 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1712 - print-atal.c: Fix an alignment bug (thanks to
1713 stanonik@nprdc.navy.mil) Add missing printf() argument.
1715 - print-bootp.c: First attempt at decoding the vendor buffer.
1717 - print-domain.c: Fix truncation checks.
1719 - print-icmp.c: Calculate length of packets from the ip header.
1721 - print-ip.c: Print frag id in decimal (so it's easier to match up
1722 with non-frags). Add support for ospf, egp and igmp.
1724 - print-nfs.c: Lots of changes.
1726 - print-ntp.c: Make some verbose output depend on -v.
1728 - print-snmp.c: New version from John LoVerso.
1730 - print-tcp.c: Print rfc1072 tcp options.
1732 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1733 (microseconds) worth of precision. Fix uid bugs.
1735 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1736 With this option, you can create an architecture independent binary
1737 trace file in real time, without the overhead of the packet printer.
1738 At a later time, the packets can be filtered (again) and printed.
1740 - BSD is supported. You must have BPF in your kernel.
1741 Since the filtering is now done in the kernel, fewer packets are
1742 dropped. In fact, with BPF and the packet dumper option, a measly
1743 Sun 3/50 can keep up with a busy network.
1745 - Compressed SLIP packets can now be dumped, provided you use our
1746 SLIP software and BPF. These packets are dumped as any other IP
1747 packet; the compressed headers are dumped with the '-e' option.
1749 - Machines with little-endian byte ordering are supported (thanks to
1752 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1754 - IBM RT and Stanford Enetfilter support has been added by
1755 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1756 both the vanilla Enetfilter interface, and the extended interface
1757 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1759 - TFTP packets are now printed (requests only).
1761 - BOOTP packets are now printed.
1763 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1765 - Sparc architectures, including the Sparcstation-1, are now
1766 supported thanks to Steve McCanne and Craig Leres.
1768 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1769 University (micky@cunixc.cc.columbia.edu).
1771 - IP options are now printed.
1773 - RIP packets are now printed.
1775 - There's a -v flag that prints out more information than the
1776 default (e.g., it will enable printing of IP ttl, tos and id)
1777 and -q flag that prints out less (e.g., it will disable
1778 interpretation of AppleTalk-in-UDP).
1780 - The grammar has undergone substantial changes (if you have an
1781 earlier version of tcpdump, you should re-read the manual
1784 The most useful change is the addition of an expression
1785 syntax that lets you filter on arbitrary fields or values in the
1786 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1787 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1790 The most painful change is that concatenation no longer means
1791 "and" -- e.g., you have to say "host foo and port bar" instead
1792 of "host foo port bar". The up side to this down is that
1793 repeated qualifiers can be omitted, making most filter
1794 expressions shorter. E.g., you can now say "ip host foo and
1795 (bar or baz)" to look at ip traffic between hosts foo and bar or
1796 between hosts foo and baz. [The old way of saying this was "ip
1797 host foo and (ip host bar or ip host baz)".]
1799 v2.0 Sun Jan 13 12:20:40 PST 1991
1801 - Initial public release.
