1087 Marty Leisner (leisner@sdsp.mc.xerox.com)
1089 - Add a local autoconf macro to check for routines in libraries; the
1090 autoconf version is broken (it only puts the library name in the
1091 cache variable name). Thanks to John Hawkinson.
1093 - Add a local autoconf macro to check for types; the autoconf version
1094 is broken (it uses grep instead of actually compiling a code fragment).
1096 - Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header

1138 - Print arp hardware type in host order. Thanks to Onno van der Linden
1141 - Avoid solaris compiler warnings. Thanks to Bruce Barnett
1142 (barnett@grymoire.crd.ge.com)
1144 - Fix rip printer to not print one more route than is actually in the

1151 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1153 - Rewrite ospf printer to improve truncation checks.
1155 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1156 (davids@secnet.com). Also, check tcp options to make sure they ar
1157 actually in the tcp header (in addition to the normal truncation
1158 checks). Fix the SACK code to print the N blocks (instead of the
1159 first block N times).
1161 - Don't say really small UDP packets are truncated just because they
1162 aren't big enough to be a RPC. As noted by David Sacerdote.
1164 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1166 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1169 - Print mtu for icmp unreach need frag packets. Thanks to John
1170 Hawkinson (jhawk@mit.edu)
1172 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1175 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1176 (kushida@trl.ibm.co.jp)
1178 - Check igmp checksum if possible. Thanks to John Hawkinson.
1180 - Made changes for SINIX. Thanks to Andrej Borsenkow

1186 - Avoid infinite loop in tcp options printing code. Thanks to Jeffrey
1187 Mogul (mogul@pa.dec.com)
1189 - Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
1190 Thanks to John Hawkinson.
1192 - Added some more packet truncation checks.

1195 signal() has different semantics on these systems.
1197 - Fixed some more alignment problems on the alpha.
1199 - Add code to massage unprintable characters in the domain and ipx
1200 printers. Thanks to John Hawkinson.

1262 - Port to GNU autoconf.
1264 - Add support for printing DVMRP and PIM traffic thanks to
1265 Havard Eidnes (Havard.Eidnes@runit.sintef.no).

1268 define being referenced. Reported by Terry Kennedy.
1270 - Minor fixes to the man page thanks to Mark Andrews.
1272 - Endian fixes to RTP and vat packet dumpers, thanks to Bruce Mah

1310 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1313 - Don't checksum ip header if we don't have all of it. Thanks to John
1314 Hawkinson (jhawk@mit.edu).
1316 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1317 Honig (jhc@bsdi.com)
1320 v3.1a1 Wed May 3 19:21:11 PDT 1995
1322 - Include time.h when SVR4 is defined to avoid problems under Solaris
1325 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1326 strings, not the local buffer. Thanks to Stefan Petri
1327 (petri@ibr.cs.tu-bs.de).
1329 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1330 that the selected value was not used. Thanks to Pascal Hennequin
1331 (Pascal.Hennequin@hugo.int-evry.fr).
1333 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1335 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1337 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1339 - Although there never was a 3.0.3 release, the linux boys cleverly
1340 "released" one in late 1995.
1342 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1344 - Change configuration to not use gcc v2 flags with gcc v1.
1346 - Redo gmt2local() so that it works under BSDI (which seems to return
1347 an empty timezone struct from gettimeofday()). Based on report from
1348 Terry Kennedy (terry@spcvxa.spc.edu).
1350 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1351 on report from Mark Andrews (mandrews@alias.com).
1353 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1354 Orth (ro@techfak.uni-bielefeld.de).
1356 - Fixed printout of connection id for uncompressed tcp slip packets.
1357 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1359 - Hack around deficiency in Ultrix's make.

1363 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1365 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1367 v3.0 Mon Jun 20 19:23:27 PDT 1994
1369 - Added support for printing tcp option timestamps thanks to
1370 Mark Andrews (mandrews@alias.com).
1372 - Reorganize protocol dumpers to take const pointers to packets so they
1373 never change the contents (i.e., they used to do endian conversions
1374 in place). Previously, whenever more than one pass was taken over
1375 the packet, the packet contents would be dumped incorrectly (i.e.,
1376 the output form -x would be wrong on little endian machines because
1377 the protocol dumpers would modify the data). Thanks to Charles Hannum
1378 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1380 - Added support for decnet protocol dumping thanks to Jeff Mogul
1383 - Fix bug that caused length of packet to be incorrectly printed
1384 (off by ether header size) for unknown ethernet types thanks
1385 to Greg Miller (gmiller@kayak.mitre.org).
1387 - Added support for IPX protocol dumping thanks to Brad Parker
1390 - Added check to verify IP header checksum under -v thanks to
1391 Brad Parker (brad@fcr.com).
1393 - Move packet capture code to new libpcap library (which is
1394 packaged separately).
1396 - Prototype everything and assume an ansi compiler.
1398 - print-arp.c: Print hardware ethernet addresses if they're not
1401 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1402 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1404 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1407 - print-icmp.c: Byte swap netmask before printing. Thanks to
1408 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1410 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1411 By default, only the inner packet is dumped, appended with the token
1412 "(encap)". Under -v, both the inner and output packets are dumped
1413 (on the same line). Note that the filter applies to the original packet,
1414 not the encapsulated packet. So if you run tcpdump on a net with an
1415 IP Multicast tunnel, you cannot filter out the datagrams using the
1416 conventional syntax. (You can filter away all the ip-in-ip traffic
1417 with "not ip proto 4".)
1419 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1420 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1422 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1424 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1425 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1426 Add && and || operators
1428 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1430 - Fix bug with -c flag.
1432 v2.2 Fri May 22 17:19:41 PDT 1992
1434 - savefile.c: Remove hack that shouldn't have been exported. Add
1437 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1438 matches non-echo/reply ICMP packets.
1440 - Many improvements to filter code optimizer.
1442 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1443 so that protocol qualifications are allowed. For example, "ip broadcast"
1444 and "ether multicast" are valid filters.
1446 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1447 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1448 patches to netinet/if_loop.c.
1450 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1451 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1453 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1455 v2.1 Tue Jan 28 11:00:14 PST 1992
1457 - Internal release (never publicly exported).
1459 v2.0.1 Sun Jan 26 21:10:10 PDT
1461 - Various byte ordering fixes.
1463 - Add truncation checks.
1465 - inet.c: Support BSD style SIOCGIFCONF.
1467 - nametoaddr.c: Handle multi addresses for single host.
1469 - optimize.c: Rewritten.
1471 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1474 - print-atal.c: Fix an alignment bug (thanks to
1475 stanonik@nprdc.navy.mil) Add missing printf() argument.
1477 - print-bootp.c: First attempt at decoding the vendor buffer.
1479 - print-domain.c: Fix truncation checks.
1481 - print-icmp.c: Calculate length of packets from the ip header.
1483 - print-ip.c: Print frag id in decimal (so it's easier to match up
1484 with non-frags). Add support for ospf, egp and igmp.
1486 - print-nfs.c: Lots of changes.
1488 - print-ntp.c: Make some verbose output depend on -v.
1490 - print-snmp.c: New version from John LoVerso.
1492 - print-tcp.c: Print rfc1072 tcp options.
1494 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1495 (microseconds) worth of precision. Fix uid bugs.
1497 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1498 With this option, you can create an architecture independent binary
1499 trace file in real time, without the overhead of the packet printer.
1500 At a later time, the packets can be filtered (again) and printed.
1502 - BSD is supported. You must have BPF in your kernel.
1503 Since the filtering is now done in the kernel, fewer packets are
1504 dropped. In fact, with BPF and the packet dumper option, a measly
1505 Sun 3/50 can keep up with a busy network.
1507 - Compressed SLIP packets can now be dumped, provided you use our
1508 SLIP software and BPF. These packets are dumped as any other IP
1509 packet; the compressed headers are dumped with the '-e' option.
1511 - Machines with little-endian byte ordering are supported (thanks to
1514 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1516 - IBM RT and Stanford Enetfilter support has been added by
1517 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1518 both the vanilla Enetfilter interface, and the extended interface
1519 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1521 - TFTP packets are now printed (requests only).
1523 - BOOTP packets are now printed.
1525 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1527 - Sparc architectures, including the Sparcstation-1, are now
1528 supported thanks to Steve McCanne and Craig Leres.
1530 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1531 University (micky@cunixc.cc.columbia.edu).
1533 - IP options are now printed.
1535 - RIP packets are now printed.
1537 - There's a -v flag that prints out more information than the
1538 default (e.g., it will enable printing of IP ttl, tos and id)
1539 and -q flag that prints out less (e.g., it will disable
1540 interpretation of AppleTalk-in-UDP).
1542 - The grammar has undergone substantial changes (if you have an
1543 earlier version of tcpdump, you should re-read the manual
1546 The most useful change is the addition of an expression
1547 syntax that lets you filter on arbitrary fields or values in the
1548 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1549 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1552 The most painful change is that concatenation no longer means
1553 "and" -- e.g., you have to say "host foo and port bar" instead
1554 of "host foo port bar". The up side to this down is that
1555 repeated qualifiers can be omitted, making most filter
1556 expressions shorter. E.g., you can now say "ip host foo and
1557 (bar or baz)" to look at ip traffic between hosts foo and bar or
1558 between hosts foo and baz. [The old way of saying this was "ip
1559 host foo and (ip host bar or ip host baz)".]
1561 v2.0 Sun Jan 13 12:20:40 PST 1991
1563 - Initial public release.
