1323 checks). Fix the SACK code to print the N blocks (instead of the
1324 first block N times).
1326 - Don't say really small UDP packets are truncated just because they
1327 aren't big enough to be a RPC. As noted by David Sacerdote.

1512 an empty timezone struct from gettimeofday()). Based on report from
1513 Terry Kennedy (terry@spcvxa.spc.edu).
1515 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based

1534 - Added support for printing tcp option timestamps thanks to
1535 Mark Andrews (mandrews@alias.com).
1537 - Reorganize protocol dumpers to take const pointers to packets so they
1538 never change the contents (i.e., they used to do endian conversions
1539 in place). Previously, whenever more than one pass was taken over
1540 the packet, the packet contents would be dumped incorrectly (i.e.,
1541 the output form -x would be wrong on little endian machines because
1542 the protocol dumpers would modify the data). Thanks to Charles Hannum
1543 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1545 - Added support for decnet protocol dumping thanks to Jeff Mogul
1548 - Fix bug that caused length of packet to be incorrectly printed
1549 (off by ether header size) for unknown ethernet types thanks

1555 - Added check to verify IP header checksum under -v thanks to

1559 packaged separately).
1561 - Prototype everything and assume an ansi compiler.
1563 - print-arp.c: Print hardware ethernet addresses if they're not
1566 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1567 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1569 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1572 - print-icmp.c: Byte swap netmask before printing. Thanks to
1573 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1575 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1576 By default, only the inner packet is dumped, appended with the token
1577 "(encap)". Under -v, both the inner and output packets are dumped
1578 (on the same line). Note that the filter applies to the original packet,
1579 not the encapsulated packet. So if you run tcpdump on a net with an
1580 IP Multicast tunnel, you cannot filter out the datagrams using the
1581 conventional syntax. (You can filter away all the ip-in-ip traffic
1582 with "not ip proto 4".)
1584 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1585 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1587 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1589 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1590 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1591 Add && and || operators
1593 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1595 - Fix bug with -c flag.
1597 v2.2 Fri May 22 17:19:41 PDT 1992
1599 - savefile.c: Remove hack that shouldn't have been exported. Add
1602 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1603 matches non-echo/reply ICMP packets.
1605 - Many improvements to filter code optimizer.
1607 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1608 so that protocol qualifications are allowed. For example, "ip broadcast"
1609 and "ether multicast" are valid filters.
1611 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1612 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1613 patches to netinet/if_loop.c.
1615 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1616 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1618 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1620 v2.1 Tue Jan 28 11:00:14 PST 1992
1622 - Internal release (never publicly exported).
1624 v2.0.1 Sun Jan 26 21:10:10 PDT
1626 - Various byte ordering fixes.
1628 - Add truncation checks.
1630 - inet.c: Support BSD style SIOCGIFCONF.
1632 - nametoaddr.c: Handle multi addresses for single host.
1634 - optimize.c: Rewritten.
1636 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1639 - print-atal.c: Fix an alignment bug (thanks to
1640 stanonik@nprdc.navy.mil) Add missing printf() argument.
1642 - print-bootp.c: First attempt at decoding the vendor buffer.
1644 - print-domain.c: Fix truncation checks.
1646 - print-icmp.c: Calculate length of packets from the ip header.
1648 - print-ip.c: Print frag id in decimal (so it's easier to match up
1649 with non-frags). Add support for ospf, egp and igmp.
1651 - print-nfs.c: Lots of changes.
1653 - print-ntp.c: Make some verbose output depend on -v.
1655 - print-snmp.c: New version from John LoVerso.
1657 - print-tcp.c: Print rfc1072 tcp options.
1659 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1660 (microseconds) worth of precision. Fix uid bugs.
1662 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1663 With this option, you can create an architecture independent binary
1664 trace file in real time, without the overhead of the packet printer.
1665 At a later time, the packets can be filtered (again) and printed.
1667 - BSD is supported. You must have BPF in your kernel.
1668 Since the filtering is now done in the kernel, fewer packets are
1669 dropped. In fact, with BPF and the packet dumper option, a measly
1670 Sun 3/50 can keep up with a busy network.
1672 - Compressed SLIP packets can now be dumped, provided you use our
1673 SLIP software and BPF. These packets are dumped as any other IP
1674 packet; the compressed headers are dumped with the '-e' option.
1676 - Machines with little-endian byte ordering are supported (thanks to
1679 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1681 - IBM RT and Stanford Enetfilter support has been added by
1682 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1683 both the vanilla Enetfilter interface, and the extended interface
1684 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1686 - TFTP packets are now printed (requests only).
1688 - BOOTP packets are now printed.
1690 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1692 - Sparc architectures, including the Sparcstation-1, are now
1693 supported thanks to Steve McCanne and Craig Leres.
1695 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1696 University (micky@cunixc.cc.columbia.edu).
1698 - IP options are now printed.
1700 - RIP packets are now printed.
1702 - There's a -v flag that prints out more information than the
1703 default (e.g., it will enable printing of IP ttl, tos and id)
1704 and -q flag that prints out less (e.g., it will disable
1705 interpretation of AppleTalk-in-UDP).
1707 - The grammar has undergone substantial changes (if you have an
1708 earlier version of tcpdump, you should re-read the manual
1711 The most useful change is the addition of an expression
1712 syntax that lets you filter on arbitrary fields or values in the
1713 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1714 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1717 The most painful change is that concatenation no longer means
1718 "and" -- e.g., you have to say "host foo and port bar" instead
1719 of "host foo port bar". The up side to this down is that
1720 repeated qualifiers can be omitted, making most filter
1721 expressions shorter. E.g., you can now say "ip host foo and
1722 (bar or baz)" to look at ip traffic between hosts foo and bar or
1723 between hosts foo and baz. [The old way of saying this was "ip
1724 host foo and (ip host bar or ip host baz)".]
1726 v2.0 Sun Jan 13 12:20:40 PST 1991
