1326 actually in the tcp header (in addition to the normal truncation
1327 checks). Fix the SACK code to print the N blocks (instead of the
1328 first block N times).
1330 - Don't say really small UDP packets are truncated just because they
1331 aren't big enough to be a RPC. As noted by David Sacerdote.

1516 an empty timezone struct from gettimeofday()). Based on report from
1517 Terry Kennedy (terry@spcvxa.spc.edu).
1519 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based

1538 - Added support for printing tcp option timestamps thanks to
1539 Mark Andrews (mandrews@alias.com).
1541 - Reorganize protocol dumpers to take const pointers to packets so they
1542 never change the contents (i.e., they used to do endian conversions
1543 in place). Previously, whenever more than one pass was taken over
1544 the packet, the packet contents would be dumped incorrectly (i.e.,
1545 the output form -x would be wrong on little endian machines because
1546 the protocol dumpers would modify the data). Thanks to Charles Hannum
1547 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1549 - Added support for decnet protocol dumping thanks to Jeff Mogul
1552 - Fix bug that caused length of packet to be incorrectly printed

1559 - Added check to verify IP header checksum under -v thanks to
1560 Brad Parker (brad@fcr.com).
1562 - Move packet capture code to new libpcap library (which is
1563 packaged separately).
1565 - Prototype everything and assume an ansi compiler.
1567 - print-arp.c: Print hardware ethernet addresses if they're not
1570 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1571 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1573 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1576 - print-icmp.c: Byte swap netmask before printing. Thanks to
1577 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1579 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1580 By default, only the inner packet is dumped, appended with the token
1581 "(encap)". Under -v, both the inner and output packets are dumped
1582 (on the same line). Note that the filter applies to the original packet,
1583 not the encapsulated packet. So if you run tcpdump on a net with an
1584 IP Multicast tunnel, you cannot filter out the datagrams using the
1585 conventional syntax. (You can filter away all the ip-in-ip traffic
1586 with "not ip proto 4".)
1588 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1589 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1591 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1593 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1594 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1595 Add && and || operators
1597 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1599 - Fix bug with -c flag.
1601 v2.2 Fri May 22 17:19:41 PDT 1992
1603 - savefile.c: Remove hack that shouldn't have been exported. Add
1606 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1607 matches non-echo/reply ICMP packets.
1609 - Many improvements to filter code optimizer.
1611 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1612 so that protocol qualifications are allowed. For example, "ip broadcast"
1613 and "ether multicast" are valid filters.
1615 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1616 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1617 patches to netinet/if_loop.c.
1619 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1620 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1622 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1624 v2.1 Tue Jan 28 11:00:14 PST 1992
1626 - Internal release (never publicly exported).
1628 v2.0.1 Sun Jan 26 21:10:10 PDT
1630 - Various byte ordering fixes.
1632 - Add truncation checks.
1634 - inet.c: Support BSD style SIOCGIFCONF.
1636 - nametoaddr.c: Handle multi addresses for single host.
1638 - optimize.c: Rewritten.
1640 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1643 - print-atal.c: Fix an alignment bug (thanks to
1644 stanonik@nprdc.navy.mil) Add missing printf() argument.
1646 - print-bootp.c: First attempt at decoding the vendor buffer.
1648 - print-domain.c: Fix truncation checks.
1650 - print-icmp.c: Calculate length of packets from the ip header.
1652 - print-ip.c: Print frag id in decimal (so it's easier to match up
1653 with non-frags). Add support for ospf, egp and igmp.
1655 - print-nfs.c: Lots of changes.
1657 - print-ntp.c: Make some verbose output depend on -v.
1659 - print-snmp.c: New version from John LoVerso.
1661 - print-tcp.c: Print rfc1072 tcp options.
1663 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1664 (microseconds) worth of precision. Fix uid bugs.
1666 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1667 With this option, you can create an architecture independent binary
1668 trace file in real time, without the overhead of the packet printer.
1669 At a later time, the packets can be filtered (again) and printed.
1671 - BSD is supported. You must have BPF in your kernel.
1672 Since the filtering is now done in the kernel, fewer packets are
1673 dropped. In fact, with BPF and the packet dumper option, a measly
1674 Sun 3/50 can keep up with a busy network.
1676 - Compressed SLIP packets can now be dumped, provided you use our
1677 SLIP software and BPF. These packets are dumped as any other IP
1678 packet; the compressed headers are dumped with the '-e' option.
1680 - Machines with little-endian byte ordering are supported (thanks to
1683 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1685 - IBM RT and Stanford Enetfilter support has been added by
1686 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1687 both the vanilla Enetfilter interface, and the extended interface
1688 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1690 - TFTP packets are now printed (requests only).
1692 - BOOTP packets are now printed.
1694 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1696 - Sparc architectures, including the Sparcstation-1, are now
1697 supported thanks to Steve McCanne and Craig Leres.
1699 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1700 University (micky@cunixc.cc.columbia.edu).
1702 - IP options are now printed.
1704 - RIP packets are now printed.
1706 - There's a -v flag that prints out more information than the
1707 default (e.g., it will enable printing of IP ttl, tos and id)
1708 and -q flag that prints out less (e.g., it will disable
1709 interpretation of AppleTalk-in-UDP).
1711 - The grammar has undergone substantial changes (if you have an
1712 earlier version of tcpdump, you should re-read the manual
1715 The most useful change is the addition of an expression
1716 syntax that lets you filter on arbitrary fields or values in the
1717 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1718 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1721 The most painful change is that concatenation no longer means
1722 "and" -- e.g., you have to say "host foo and port bar" instead
1723 of "host foo port bar". The up side to this down is that
1724 repeated qualifiers can be omitted, making most filter
1725 expressions shorter. E.g., you can now say "ip host foo and
1726 (bar or baz)" to look at ip traffic between hosts foo and bar or
1727 between hosts foo and baz. [The old way of saying this was "ip
1728 host foo and (ip host bar or ip host baz)".]
