1078 Marty Leisner (leisner@sdsp.mc.xerox.com)
1080 - Add a local autoconf macro to check for routines in libraries; the
1081 autoconf version is broken (it only puts the library name in the
1082 cache variable name). Thanks to John Hawkinson.
1084 - Add a local autoconf macro to check for types; the autoconf version
1085 is broken (it uses grep instead of actually compiling a code fragment).
1087 - Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header

1127 - Enable "ip_hl vs. ip_vhl" workaround for OSF4 too.
1129 - Print arp hardware type in host order. Thanks to Onno van der Linden
1132 - Avoid solaris compiler warnings. Thanks to Bruce Barnett
1133 (barnett@grymoire.crd.ge.com)
1135 - Fix rip printer to not print one more route than is actually in the
1136 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
1137 Bill Fenner (fenner@parc.xerox.com)
1139 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.

1142 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1144 - Rewrite ospf printer to improve truncation checks.
1146 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1147 (davids@secnet.com). Also, check tcp options to make sure they ar
1148 actually in the tcp header (in addition to the normal truncation
1149 checks). Fix the SACK code to print the N blocks (instead of the
1150 first block N times).
1152 - Don't say really small UDP packets are truncated just because they
1153 aren't big enough to be a RPC. As noted by David Sacerdote.
1155 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1157 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1160 - Print mtu for icmp unreach need frag packets. Thanks to John
1161 Hawkinson (jhawk@mit.edu)
1163 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1166 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1167 (kushida@trl.ibm.co.jp)
1169 - Check igmp checksum if possible. Thanks to John Hawkinson.
1171 - Made changes for SINIX. Thanks to Andrej Borsenkow
1172 (borsenkow.msk@sni.de)

1181 Thanks to John Hawkinson.
1183 - Added some more packet truncation checks.

1186 signal() has different semantics on these systems.
1188 - Fixed some more alignment problems on the alpha.
1190 - Add code to massage unprintable characters in the domain and ipx
1191 printers. Thanks to John Hawkinson.

1201 - Added an igrp printer. Thanks to Francis Dupont
1202 (francis.dupont@inria.fr)
1204 - Print IPX net numbers in hex a la Novell Netware. Thanks to Terry
1205 Kennedy (terry@spcvxa.spc.edu)

1253 - Port to GNU autoconf.
1255 - Add support for printing DVMRP and PIM traffic thanks to
1256 Havard Eidnes (Havard.Eidnes@runit.sintef.no).

1259 define being referenced. Reported by Terry Kennedy.
1261 - Minor fixes to the man page thanks to Mark Andrews.
1263 - Endian fixes to RTP and vat packet dumpers, thanks to Bruce Mah

1305 Hawkinson (jhawk@mit.edu).
1307 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1308 Honig (jhc@bsdi.com)
1311 v3.1a1 Wed May 3 19:21:11 PDT 1995
1313 - Include time.h when SVR4 is defined to avoid problems under Solaris
1316 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1317 strings, not the local buffer. Thanks to Stefan Petri
1318 (petri@ibr.cs.tu-bs.de).
1320 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1321 that the selected value was not used. Thanks to Pascal Hennequin
1322 (Pascal.Hennequin@hugo.int-evry.fr).
1324 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1326 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1328 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1330 - Although there never was a 3.0.3 release, the linux boys cleverly
1331 "released" one in late 1995.
1333 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1335 - Change configuration to not use gcc v2 flags with gcc v1.
1337 - Redo gmt2local() so that it works under BSDI (which seems to return
1338 an empty timezone struct from gettimeofday()). Based on report from
1339 Terry Kennedy (terry@spcvxa.spc.edu).
1341 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1342 on report from Mark Andrews (mandrews@alias.com).
1344 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1345 Orth (ro@techfak.uni-bielefeld.de).
1347 - Fixed printout of connection id for uncompressed tcp slip packets.
1348 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1350 - Hack around deficiency in Ultrix's make.
1352 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1354 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1356 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1358 v3.0 Mon Jun 20 19:23:27 PDT 1994
1360 - Added support for printing tcp option timestamps thanks to
1361 Mark Andrews (mandrews@alias.com).
1363 - Reorganize protocol dumpers to take const pointers to packets so they
1364 never change the contents (i.e., they used to do endian conversions
1365 in place). Previously, whenever more than one pass was taken over
1366 the packet, the packet contents would be dumped incorrectly (i.e.,
1367 the output form -x would be wrong on little endian machines because
1368 the protocol dumpers would modify the data). Thanks to Charles Hannum
1369 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1371 - Added support for decnet protocol dumping thanks to Jeff Mogul
1374 - Fix bug that caused length of packet to be incorrectly printed
1375 (off by ether header size) for unknown ethernet types thanks
1376 to Greg Miller (gmiller@kayak.mitre.org).
1378 - Added support for IPX protocol dumping thanks to Brad Parker
1381 - Added check to verify IP header checksum under -v thanks to
1382 Brad Parker (brad@fcr.com).
1384 - Move packet capture code to new libpcap library (which is
1385 packaged separately).
1387 - Prototype everything and assume an ansi compiler.
1389 - print-arp.c: Print hardware ethernet addresses if they're not
1392 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1393 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1395 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1398 - print-icmp.c: Byte swap netmask before printing. Thanks to
1399 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1401 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1402 By default, only the inner packet is dumped, appended with the token
1403 "(encap)". Under -v, both the inner and output packets are dumped
1404 (on the same line). Note that the filter applies to the original packet,
1405 not the encapsulated packet. So if you run tcpdump on a net with an
1406 IP Multicast tunnel, you cannot filter out the datagrams using the
1407 conventional syntax. (You can filter away all the ip-in-ip traffic
1408 with "not ip proto 4".)
1410 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1411 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1413 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1415 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1416 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1417 Add && and || operators
1419 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1421 - Fix bug with -c flag.
1423 v2.2 Fri May 22 17:19:41 PDT 1992
1425 - savefile.c: Remove hack that shouldn't have been exported. Add
1428 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1429 matches non-echo/reply ICMP packets.
1431 - Many improvements to filter code optimizer.
1433 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1434 so that protocol qualifications are allowed. For example, "ip broadcast"
1435 and "ether multicast" are valid filters.
1437 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1438 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1439 patches to netinet/if_loop.c.
1441 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1442 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1444 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1446 v2.1 Tue Jan 28 11:00:14 PST 1992
1448 - Internal release (never publicly exported).
1450 v2.0.1 Sun Jan 26 21:10:10 PDT
1452 - Various byte ordering fixes.
1454 - Add truncation checks.
1456 - inet.c: Support BSD style SIOCGIFCONF.
1458 - nametoaddr.c: Handle multi addresses for single host.
1460 - optimize.c: Rewritten.
1462 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1465 - print-atal.c: Fix an alignment bug (thanks to
1466 stanonik@nprdc.navy.mil) Add missing printf() argument.
1468 - print-bootp.c: First attempt at decoding the vendor buffer.
1470 - print-domain.c: Fix truncation checks.
1472 - print-icmp.c: Calculate length of packets from the ip header.
1474 - print-ip.c: Print frag id in decimal (so it's easier to match up
1475 with non-frags). Add support for ospf, egp and igmp.
1477 - print-nfs.c: Lots of changes.
1479 - print-ntp.c: Make some verbose output depend on -v.
1481 - print-snmp.c: New version from John LoVerso.
1483 - print-tcp.c: Print rfc1072 tcp options.
1485 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1486 (microseconds) worth of precision. Fix uid bugs.
1488 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1489 With this option, you can create an architecture independent binary
1490 trace file in real time, without the overhead of the packet printer.
1491 At a later time, the packets can be filtered (again) and printed.
1493 - BSD is supported. You must have BPF in your kernel.
1494 Since the filtering is now done in the kernel, fewer packets are
1495 dropped. In fact, with BPF and the packet dumper option, a measly
1496 Sun 3/50 can keep up with a busy network.
1498 - Compressed SLIP packets can now be dumped, provided you use our
1499 SLIP software and BPF. These packets are dumped as any other IP
1500 packet; the compressed headers are dumped with the '-e' option.
1502 - Machines with little-endian byte ordering are supported (thanks to
1505 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1507 - IBM RT and Stanford Enetfilter support has been added by
1508 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1509 both the vanilla Enetfilter interface, and the extended interface
1510 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1512 - TFTP packets are now printed (requests only).
1514 - BOOTP packets are now printed.
1516 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1518 - Sparc architectures, including the Sparcstation-1, are now
1519 supported thanks to Steve McCanne and Craig Leres.
1521 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1522 University (micky@cunixc.cc.columbia.edu).
1524 - IP options are now printed.
1526 - RIP packets are now printed.
1528 - There's a -v flag that prints out more information than the
1529 default (e.g., it will enable printing of IP ttl, tos and id)
1530 and -q flag that prints out less (e.g., it will disable
1531 interpretation of AppleTalk-in-UDP).
1533 - The grammar has undergone substantial changes (if you have an
1534 earlier version of tcpdump, you should re-read the manual
1537 The most useful change is the addition of an expression
1538 syntax that lets you filter on arbitrary fields or values in the
1539 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1540 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1543 The most painful change is that concatenation no longer means
1544 "and" -- e.g., you have to say "host foo and port bar" instead
1545 of "host foo port bar". The up side to this down is that
1546 repeated qualifiers can be omitted, making most filter
1547 expressions shorter. E.g., you can now say "ip host foo and
1548 (bar or baz)" to look at ip traffic between hosts foo and bar or
1549 between hosts foo and baz. [The old way of saying this was "ip
1550 host foo and (ip host bar or ip host baz)".]
1552 v2.0 Sun Jan 13 12:20:40 PST 1991
1554 - Initial public release.
