1411 checks). Fix the SACK code to print the N blocks (instead of the
1412 first block N times).
1414 - Don't say really small UDP packets are truncated just because they
1415 aren't big enough to be a RPC. As noted by David Sacerdote.

1532 - Document -dd and -ddd. Resulted from a bug report from Charlie Slater
1533 (cslater@imatek.com).
1535 - Check return status from malloc/calloc/etc.
1537 - Check return status from pcap_loop() so we can print an error and
1538 exit with a bad status if there were problems.
1540 - Bail if ip option length is <= 0. Resulted from a bug report from
1541 Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).

1554 "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).
1556 - Rewrote tcp options printer code to check for truncation. Added
1557 selective acknowledgment case.
1559 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
1562 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
1563 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1566 - Don't checksum ip header if we don't have all of it. Thanks to John
1567 Hawkinson (jhawk@mit.edu).
1569 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1570 Honig (jhc@bsdi.com)
1573 v3.1a1 Wed May 3 19:21:11 PDT 1995
1575 - Include time.h when SVR4 is defined to avoid problems under Solaris
1578 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1579 strings, not the local buffer. Thanks to Stefan Petri
1580 (petri@ibr.cs.tu-bs.de).
1582 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1583 that the selected value was not used. Thanks to Pascal Hennequin
1584 (Pascal.Hennequin@hugo.int-evry.fr).
1586 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1588 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1590 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1592 - Although there never was a 3.0.3 release, the linux boys cleverly
1593 "released" one in late 1995.
1595 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1597 - Change configuration to not use gcc v2 flags with gcc v1.
1599 - Redo gmt2local() so that it works under BSDI (which seems to return
1600 an empty timezone struct from gettimeofday()). Based on report from
1601 Terry Kennedy (terry@spcvxa.spc.edu).
1603 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1604 on report from Mark Andrews (mandrews@alias.com).
1606 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1607 Orth (ro@techfak.uni-bielefeld.de).
1609 - Fixed printout of connection id for uncompressed tcp slip packets.
1610 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1612 - Hack around deficiency in Ultrix's make.
1614 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1616 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1618 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1620 v3.0 Mon Jun 20 19:23:27 PDT 1994
1622 - Added support for printing tcp option timestamps thanks to
1623 Mark Andrews (mandrews@alias.com).
1625 - Reorganize protocol dumpers to take const pointers to packets so they
1626 never change the contents (i.e., they used to do endian conversions
1627 in place). Previously, whenever more than one pass was taken over
1628 the packet, the packet contents would be dumped incorrectly (i.e.,
1629 the output form -x would be wrong on little endian machines because
1630 the protocol dumpers would modify the data). Thanks to Charles Hannum
1631 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1633 - Added support for decnet protocol dumping thanks to Jeff Mogul
1636 - Fix bug that caused length of packet to be incorrectly printed
1637 (off by ether header size) for unknown ethernet types thanks
1638 to Greg Miller (gmiller@kayak.mitre.org).
1640 - Added support for IPX protocol dumping thanks to Brad Parker
1643 - Added check to verify IP header checksum under -v thanks to
1644 Brad Parker (brad@fcr.com).
1646 - Move packet capture code to new libpcap library (which is
1647 packaged separately).
1649 - Prototype everything and assume an ansi compiler.
1651 - print-arp.c: Print hardware ethernet addresses if they're not
1654 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1655 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1657 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1660 - print-icmp.c: Byte swap netmask before printing. Thanks to
1661 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1663 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1664 By default, only the inner packet is dumped, appended with the token
1665 "(encap)". Under -v, both the inner and output packets are dumped
1666 (on the same line). Note that the filter applies to the original packet,
1667 not the encapsulated packet. So if you run tcpdump on a net with an
1668 IP Multicast tunnel, you cannot filter out the datagrams using the
1669 conventional syntax. (You can filter away all the ip-in-ip traffic
1670 with "not ip proto 4".)
1672 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1673 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1675 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1677 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1678 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1679 Add && and || operators
1681 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1683 - Fix bug with -c flag.
1685 v2.2 Fri May 22 17:19:41 PDT 1992
1687 - savefile.c: Remove hack that shouldn't have been exported. Add
1690 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1691 matches non-echo/reply ICMP packets.
1693 - Many improvements to filter code optimizer.
1695 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1696 so that protocol qualifications are allowed. For example, "ip broadcast"
1697 and "ether multicast" are valid filters.
1699 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1700 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1701 patches to netinet/if_loop.c.
1703 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1704 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1706 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1708 v2.1 Tue Jan 28 11:00:14 PST 1992
1710 - Internal release (never publicly exported).
1712 v2.0.1 Sun Jan 26 21:10:10 PDT
1714 - Various byte ordering fixes.
1716 - Add truncation checks.
1718 - inet.c: Support BSD style SIOCGIFCONF.
1720 - nametoaddr.c: Handle multi addresses for single host.
1722 - optimize.c: Rewritten.
1724 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1727 - print-atal.c: Fix an alignment bug (thanks to
1728 stanonik@nprdc.navy.mil) Add missing printf() argument.
1730 - print-bootp.c: First attempt at decoding the vendor buffer.
1732 - print-domain.c: Fix truncation checks.
1734 - print-icmp.c: Calculate length of packets from the ip header.
1736 - print-ip.c: Print frag id in decimal (so it's easier to match up
1737 with non-frags). Add support for ospf, egp and igmp.
1739 - print-nfs.c: Lots of changes.
1741 - print-ntp.c: Make some verbose output depend on -v.
1743 - print-snmp.c: New version from John LoVerso.
1745 - print-tcp.c: Print rfc1072 tcp options.
1747 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1748 (microseconds) worth of precision. Fix uid bugs.
1750 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1751 With this option, you can create an architecture independent binary
1752 trace file in real time, without the overhead of the packet printer.
1753 At a later time, the packets can be filtered (again) and printed.
1755 - BSD is supported. You must have BPF in your kernel.
1756 Since the filtering is now done in the kernel, fewer packets are
1757 dropped. In fact, with BPF and the packet dumper option, a measly
1758 Sun 3/50 can keep up with a busy network.
1760 - Compressed SLIP packets can now be dumped, provided you use our
1761 SLIP software and BPF. These packets are dumped as any other IP
1762 packet; the compressed headers are dumped with the '-e' option.
1764 - Machines with little-endian byte ordering are supported (thanks to
1767 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1769 - IBM RT and Stanford Enetfilter support has been added by
1770 Rayan Zachariassen <rayan@canet.ca>. tcpdump has been tested under
1771 both the vanilla Enetfilter interface, and the extended interface
1772 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1774 - TFTP packets are now printed (requests only).
1776 - BOOTP packets are now printed.
1778 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1780 - Sparc architectures, including the Sparcstation-1, are now
1781 supported thanks to Steve McCanne and Craig Leres.
1783 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1784 University (micky@cunixc.cc.columbia.edu).
1786 - IP options are now printed.
1788 - RIP packets are now printed.
1790 - There's a -v flag that prints out more information than the
1791 default (e.g., it will enable printing of IP ttl, tos and id)
1792 and -q flag that prints out less (e.g., it will disable
1793 interpretation of AppleTalk-in-UDP).
1795 - The grammar has undergone substantial changes (if you have an
1796 earlier version of tcpdump, you should re-read the manual
1799 The most useful change is the addition of an expression
1800 syntax that lets you filter on arbitrary fields or values in the
1801 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1802 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1805 The most painful change is that concatenation no longer means
1806 "and" -- e.g., you have to say "host foo and port bar" instead
1807 of "host foo port bar". The up side to this down is that
1808 repeated qualifiers can be omitted, making most filter
1809 expressions shorter. E.g., you can now say "ip host foo and
1810 (bar or baz)" to look at ip traffic between hosts foo and bar or
1811 between hosts foo and baz. [The old way of saying this was "ip
1812 host foo and (ip host bar or ip host baz)".]
1814 v2.0 Sun Jan 13 12:20:40 PST 1991
