1064 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
1066 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
1067 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1069 - Rewrite ospf printer to improve truncation checks.
1071 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1072 (davids@secnet.com). Also, check tcp options to make sure they ar
1073 actually in the tcp header (in addition to the normal truncation
1074 checks). Fix the SACK code to print the N blocks (instead of the
1075 first block N times).
1077 - Don't say really small UDP packets are truncated just because they
1078 aren't big enough to be a RPC. As noted by David Sacerdote.

1178 - Port to GNU autoconf.
1180 - Add support for printing DVMRP and PIM traffic thanks to
1181 Havard Eidnes (Havard.Eidnes@runit.sintef.no).
1183 - Fix AppleTalk, IPX and DECnet byte order problems due to wrong endian
1184 define being referenced. Reported by Terry Kennedy.
1186 - Minor fixes to the man page thanks to Mark Andrews.
1188 - Endian fixes to RTP and vat packet dumpers, thanks to Bruce Mah
1189 (bmah@cs.berkeley.edu).
1191 - Added support for new dns types, thanks to Rainer Orth.

1195 - Document -dd and -ddd. Resulted from a bug report from Charlie Slater
1196 (cslater@imatek.com).
1198 - Check return status from malloc/calloc/etc.
1200 - Check return status from pcap_loop() so we can print an error and
1201 exit with a bad status if there were problems.
1203 - Bail if ip option length is <= 0. Resulted from a bug report from
1204 Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).

1220 selective acknowledgment case.
1222 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
1225 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
1226 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1229 - Don't checksum ip header if we don't have all of it. Thanks to John
1230 Hawkinson (jhawk@mit.edu).
1232 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1233 Honig (jhc@bsdi.com)
1236 v3.1a1 Wed May 3 19:21:11 PDT 1995
1238 - Include time.h when SVR4 is defined to avoid problems under Solaris
1241 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1242 strings, not the local buffer. Thanks to Stefan Petri
1243 (petri@ibr.cs.tu-bs.de).
1245 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1246 that the selected value was not used. Thanks to Pascal Hennequin
1247 (Pascal.Hennequin@hugo.int-evry.fr).
1249 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1251 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1253 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1255 - Although there never was a 3.0.3 release, the linux boys cleverly
1256 "released" one in late 1995.
1258 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1260 - Change configuration to not use gcc v2 flags with gcc v1.
1262 - Redo gmt2local() so that it works under BSDI (which seems to return
1263 an empty timezone struct from gettimeofday()). Based on report from
1264 Terry Kennedy (terry@spcvxa.spc.edu).
1266 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1267 on report from Mark Andrews (mandrews@alias.com).
1269 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1270 Orth (ro@techfak.uni-bielefeld.de).
1272 - Fixed printout of connection id for uncompressed tcp slip packets.
1273 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1275 - Hack around deficiency in Ultrix's make.
1277 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1279 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1281 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1283 v3.0 Mon Jun 20 19:23:27 PDT 1994
1285 - Added support for printing tcp option timestamps thanks to
1286 Mark Andrews (mandrews@alias.com).
1288 - Reorganize protocol dumpers to take const pointers to packets so they
1289 never change the contents (i.e., they used to do endian conversions
1290 in place). Previously, whenever more than one pass was taken over
1291 the packet, the packet contents would be dumped incorrectly (i.e.,
1292 the output form -x would be wrong on little endian machines because
1293 the protocol dumpers would modify the data). Thanks to Charles Hannum
1294 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1296 - Added support for decnet protocol dumping thanks to Jeff Mogul
1299 - Fix bug that caused length of packet to be incorrectly printed
1300 (off by ether header size) for unknown ethernet types thanks
1301 to Greg Miller (gmiller@kayak.mitre.org).
1303 - Added support for IPX protocol dumping thanks to Brad Parker
1306 - Added check to verify IP header checksum under -v thanks to
1307 Brad Parker (brad@fcr.com).
1309 - Move packet capture code to new libpcap library (which is
1310 packaged separately).
1312 - Prototype everything and assume an ansi compiler.
1314 - print-arp.c: Print hardware ethernet addresses if they're not
1317 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1318 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1320 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1323 - print-icmp.c: Byte swap netmask before printing. Thanks to
1324 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1326 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1327 By default, only the inner packet is dumped, appended with the token
1328 "(encap)". Under -v, both the inner and output packets are dumped
1329 (on the same line). Note that the filter applies to the original packet,
1330 not the encapsulated packet. So if you run tcpdump on a net with an
1331 IP Multicast tunnel, you cannot filter out the datagrams using the
1332 conventional syntax. (You can filter away all the ip-in-ip traffic
1333 with "not ip proto 4".)
1335 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1336 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1338 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1340 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1341 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1342 Add && and || operators
1344 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1346 - Fix bug with -c flag.
1348 v2.2 Fri May 22 17:19:41 PDT 1992
1350 - savefile.c: Remove hack that shouldn't have been exported. Add
1353 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1354 matches non-echo/reply ICMP packets.
1356 - Many improvements to filter code optimizer.
1358 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1359 so that protocol qualifications are allowed. For example, "ip broadcast"
1360 and "ether multicast" are valid filters.
1362 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1363 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1364 patches to netinet/if_loop.c.
1366 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1367 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1369 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1371 v2.1 Tue Jan 28 11:00:14 PST 1992
1373 - Internal release (never publically exported).
1375 v2.0.1 Sun Jan 26 21:10:10 PDT
1377 - Various byte ordering fixes.
1379 - Add truncation checks.
1381 - inet.c: Support BSD style SIOCGIFCONF.
1383 - nametoaddr.c: Handle multi addresses for single host.
1385 - optimize.c: Rewritten.
1387 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1390 - print-atal.c: Fix an alignment bug (thanks to
1391 stanonik@nprdc.navy.mil) Add missing printf() argument.
1393 - print-bootp.c: First attempt at decoding the vendor buffer.
1395 - print-domain.c: Fix truncation checks.
1397 - print-icmp.c: Calculate length of packets from the ip header.
1399 - print-ip.c: Print frag id in decimal (so it's easier to match up
1400 with non-frags). Add support for ospf, egp and igmp.
1402 - print-nfs.c: Lots of changes.
1404 - print-ntp.c: Make some verbose output depend on -v.
1406 - print-snmp.c: New version from John LoVerso.
1408 - print-tcp.c: Print rfc1072 tcp options.
1410 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1411 (microseconds) worth of precision. Fix uid bugs.
1413 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1414 With this option, you can create an architecture independent binary
1415 trace file in real time, without the overhead of the packet printer.
1416 At a later time, the packets can be filtered (again) and printed.
1418 - BSD is supported. You must have BPF in your kernel.
1419 Since the filtering is now done in the kernel, fewer packets are
1420 dropped. In fact, with BPF and the packet dumper option, a measly
1421 Sun 3/50 can keep up with a busy network.
1423 - Compressed SLIP packets can now be dumped, provided you use our
1424 SLIP software and BPF. These packets are dumped as any other IP
1425 packet; the compressed headers are dumped with the '-e' option.
1427 - Machines with little-endian byte ordering are supported (thanks to
1430 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1432 - IBM RT and Stanford Enetfilter support has been added by
1433 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1434 both the vanilla Enetfilter interface, and the extended interface
1435 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1437 - TFTP packets are now printed (requests only).
1439 - BOOTP packets are now printed.
1441 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1443 - Sparc architectures, including the Sparcstation-1, are now
1444 supported thanks to Steve McCanne and Craig Leres.
1446 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1447 University (micky@cunixc.cc.columbia.edu).
1449 - IP options are now printed.
1451 - RIP packets are now printed.
1453 - There's a -v flag that prints out more information than the
1454 default (e.g., it will enable printing of IP ttl, tos and id)
1455 and -q flag that prints out less (e.g., it will disable
1456 interpretation of AppleTalk-in-UDP).
1458 - The grammar has undergone substantial changes (if you have an
1459 earlier version of tcpdump, you should re-read the manual
1462 The most useful change is the addition of an expression
1463 syntax that lets you filter on arbitrary fields or values in the
1464 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1465 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1468 The most painful change is that concatenation no longer means
1469 "and" -- e.g., you have to say "host foo and port bar" instead
1470 of "host foo port bar". The up side to this down is that
1471 repeated qualifiers can be omitted, making most filter
1472 expressions shorter. E.g., you can now say "ip host foo and
1473 (bar or baz)" to look at ip traffic between hosts foo and bar or
1474 between hosts foo and baz. [The old way of saying this was "ip
1475 host foo and (ip host bar or ip host baz)".]
1477 v2.0 Sun Jan 13 12:20:40 PST 1991
1479 - Initial public release.
