1164 autoconf version is broken (it only puts the library name in the
1165 cache variable name). Thanks to John Hawkinson.
1167 - Add a local autoconf macro to check for types; the autoconf version
1168 is broken (it uses grep instead of actually compiling a code fragment).

1230 (davids@secnet.com). Also, check tcp options to make sure they ar
1231 actually in the tcp header (in addition to the normal truncation
1232 checks). Fix the SACK code to print the N blocks (instead of the
1233 first block N times).
1235 - Don't say really small UDP packets are truncated just because they
1236 aren't big enough to be a RPC. As noted by David Sacerdote.
1238 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1240 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1243 - Print mtu for icmp unreach need frag packets. Thanks to John
1244 Hawkinson (jhawk@mit.edu)
1246 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1249 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1250 (kushida@trl.ibm.co.jp)
1252 - Check igmp checksum if possible. Thanks to John Hawkinson.
1254 - Made changes for SINIX. Thanks to Andrej Borsenkow

1384 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1387 - Don't checksum ip header if we don't have all of it. Thanks to John
1388 Hawkinson (jhawk@mit.edu).

1400 strings, not the local buffer. Thanks to Stefan Petri
1401 (petri@ibr.cs.tu-bs.de).
1403 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1404 that the selected value was not used. Thanks to Pascal Hennequin

1407 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1409 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1411 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1413 - Although there never was a 3.0.3 release, the linux boys cleverly
1414 "released" one in late 1995.
1416 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1418 - Change configuration to not use gcc v2 flags with gcc v1.
1420 - Redo gmt2local() so that it works under BSDI (which seems to return
1421 an empty timezone struct from gettimeofday()). Based on report from
1422 Terry Kennedy (terry@spcvxa.spc.edu).
1424 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1425 on report from Mark Andrews (mandrews@alias.com).
1427 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1428 Orth (ro@techfak.uni-bielefeld.de).
1430 - Fixed printout of connection id for uncompressed tcp slip packets.
1431 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1433 - Hack around deficiency in Ultrix's make.

1437 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1439 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1441 v3.0 Mon Jun 20 19:23:27 PDT 1994
1443 - Added support for printing tcp option timestamps thanks to
1444 Mark Andrews (mandrews@alias.com).
1446 - Reorganize protocol dumpers to take const pointers to packets so they
1447 never change the contents (i.e., they used to do endian conversions
1448 in place). Previously, whenever more than one pass was taken over
1449 the packet, the packet contents would be dumped incorrectly (i.e.,
1450 the output form -x would be wrong on little endian machines because
1451 the protocol dumpers would modify the data). Thanks to Charles Hannum
1452 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1454 - Added support for decnet protocol dumping thanks to Jeff Mogul
1457 - Fix bug that caused length of packet to be incorrectly printed
1458 (off by ether header size) for unknown ethernet types thanks
1459 to Greg Miller (gmiller@kayak.mitre.org).
1461 - Added support for IPX protocol dumping thanks to Brad Parker
1464 - Added check to verify IP header checksum under -v thanks to
1465 Brad Parker (brad@fcr.com).
1467 - Move packet capture code to new libpcap library (which is
1468 packaged separately).
1470 - Prototype everything and assume an ansi compiler.
1472 - print-arp.c: Print hardware ethernet addresses if they're not
1475 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1476 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1478 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1481 - print-icmp.c: Byte swap netmask before printing. Thanks to
1482 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1484 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1485 By default, only the inner packet is dumped, appended with the token
1486 "(encap)". Under -v, both the inner and output packets are dumped
1487 (on the same line). Note that the filter applies to the original packet,
1488 not the encapsulated packet. So if you run tcpdump on a net with an
1489 IP Multicast tunnel, you cannot filter out the datagrams using the
1490 conventional syntax. (You can filter away all the ip-in-ip traffic
1491 with "not ip proto 4".)
1493 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1494 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1496 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1498 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1499 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1500 Add && and || operators
1502 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1504 - Fix bug with -c flag.
1506 v2.2 Fri May 22 17:19:41 PDT 1992
1508 - savefile.c: Remove hack that shouldn't have been exported. Add
1511 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1512 matches non-echo/reply ICMP packets.
1514 - Many improvements to filter code optimizer.
1516 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1517 so that protocol qualifications are allowed. For example, "ip broadcast"
1518 and "ether multicast" are valid filters.
1520 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1521 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1522 patches to netinet/if_loop.c.
1524 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1525 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1527 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1529 v2.1 Tue Jan 28 11:00:14 PST 1992
1531 - Internal release (never publicly exported).
1533 v2.0.1 Sun Jan 26 21:10:10 PDT
1535 - Various byte ordering fixes.
1537 - Add truncation checks.
1539 - inet.c: Support BSD style SIOCGIFCONF.
1541 - nametoaddr.c: Handle multi addresses for single host.
1543 - optimize.c: Rewritten.
1545 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1548 - print-atal.c: Fix an alignment bug (thanks to
1549 stanonik@nprdc.navy.mil) Add missing printf() argument.
1551 - print-bootp.c: First attempt at decoding the vendor buffer.
1553 - print-domain.c: Fix truncation checks.
1555 - print-icmp.c: Calculate length of packets from the ip header.
1557 - print-ip.c: Print frag id in decimal (so it's easier to match up
1558 with non-frags). Add support for ospf, egp and igmp.
1560 - print-nfs.c: Lots of changes.
1562 - print-ntp.c: Make some verbose output depend on -v.
1564 - print-snmp.c: New version from John LoVerso.
1566 - print-tcp.c: Print rfc1072 tcp options.
1568 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1569 (microseconds) worth of precision. Fix uid bugs.
1571 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1572 With this option, you can create an architecture independent binary
1573 trace file in real time, without the overhead of the packet printer.
1574 At a later time, the packets can be filtered (again) and printed.
1576 - BSD is supported. You must have BPF in your kernel.
1577 Since the filtering is now done in the kernel, fewer packets are
1578 dropped. In fact, with BPF and the packet dumper option, a measly
1579 Sun 3/50 can keep up with a busy network.
1581 - Compressed SLIP packets can now be dumped, provided you use our
1582 SLIP software and BPF. These packets are dumped as any other IP
1583 packet; the compressed headers are dumped with the '-e' option.
1585 - Machines with little-endian byte ordering are supported (thanks to
1588 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1590 - IBM RT and Stanford Enetfilter support has been added by
1591 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1592 both the vanilla Enetfilter interface, and the extended interface
1593 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1595 - TFTP packets are now printed (requests only).
1597 - BOOTP packets are now printed.
1599 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1601 - Sparc architectures, including the Sparcstation-1, are now
1602 supported thanks to Steve McCanne and Craig Leres.
1604 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1605 University (micky@cunixc.cc.columbia.edu).
1607 - IP options are now printed.
1609 - RIP packets are now printed.
1611 - There's a -v flag that prints out more information than the
1612 default (e.g., it will enable printing of IP ttl, tos and id)
1613 and -q flag that prints out less (e.g., it will disable
1614 interpretation of AppleTalk-in-UDP).
1616 - The grammar has undergone substantial changes (if you have an
1617 earlier version of tcpdump, you should re-read the manual
1620 The most useful change is the addition of an expression
1621 syntax that lets you filter on arbitrary fields or values in the
1622 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1623 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1626 The most painful change is that concatenation no longer means
1627 "and" -- e.g., you have to say "host foo and port bar" instead
1628 of "host foo port bar". The up side to this down is that
1629 repeated qualifiers can be omitted, making most filter
1630 expressions shorter. E.g., you can now say "ip host foo and
1631 (bar or baz)" to look at ip traffic between hosts foo and bar or
1632 between hosts foo and baz. [The old way of saying this was "ip
1633 host foo and (ip host bar or ip host baz)".]
