1084 Marty Leisner (leisner@sdsp.mc.xerox.com)
1086 - Add a local autoconf macro to check for routines in libraries; the
1087 autoconf version is broken (it only puts the library name in the
1088 cache variable name). Thanks to John Hawkinson.
1090 - Add a local autoconf macro to check for types; the autoconf version
1091 is broken (it uses grep instead of actually compiling a code fragment).
1093 - Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header

1135 - Print arp hardware type in host order. Thanks to Onno van der Linden
1138 - Avoid solaris compiler warnings. Thanks to Bruce Barnett
1139 (barnett@grymoire.crd.ge.com)
1141 - Fix rip printer to not print one more route than is actually in the
1142 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
1143 Bill Fenner (fenner@parc.xerox.com)
1145 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.

1148 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1150 - Rewrite ospf printer to improve truncation checks.
1152 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1153 (davids@secnet.com). Also, check tcp options to make sure they ar
1154 actually in the tcp header (in addition to the normal truncation
1155 checks). Fix the SACK code to print the N blocks (instead of the
1156 first block N times).
1158 - Don't say really small UDP packets are truncated just because they
1159 aren't big enough to be a RPC. As noted by David Sacerdote.
1161 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1163 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1166 - Print mtu for icmp unreach need frag packets. Thanks to John
1167 Hawkinson (jhawk@mit.edu)
1169 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1172 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1173 (kushida@trl.ibm.co.jp)
1175 - Check igmp checksum if possible. Thanks to John Hawkinson.
1177 - Made changes for SINIX. Thanks to Andrej Borsenkow

1192 signal() has different semantics on these systems.
1194 - Fixed some more alignment problems on the alpha.
1196 - Add code to massage unprintable characters in the domain and ipx
1197 printers. Thanks to John Hawkinson.

1259 - Port to GNU autoconf.
1261 - Add support for printing DVMRP and PIM traffic thanks to
1262 Havard Eidnes (Havard.Eidnes@runit.sintef.no).

1311 Hawkinson (jhawk@mit.edu).
1313 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1314 Honig (jhc@bsdi.com)
1317 v3.1a1 Wed May 3 19:21:11 PDT 1995
1319 - Include time.h when SVR4 is defined to avoid problems under Solaris
1322 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1323 strings, not the local buffer. Thanks to Stefan Petri
1324 (petri@ibr.cs.tu-bs.de).
1326 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1327 that the selected value was not used. Thanks to Pascal Hennequin
1328 (Pascal.Hennequin@hugo.int-evry.fr).
1330 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1332 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1334 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1336 - Although there never was a 3.0.3 release, the linux boys cleverly
1337 "released" one in late 1995.
1339 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1341 - Change configuration to not use gcc v2 flags with gcc v1.
1343 - Redo gmt2local() so that it works under BSDI (which seems to return
1344 an empty timezone struct from gettimeofday()). Based on report from
1345 Terry Kennedy (terry@spcvxa.spc.edu).
1347 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1348 on report from Mark Andrews (mandrews@alias.com).
1350 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1351 Orth (ro@techfak.uni-bielefeld.de).
1353 - Fixed printout of connection id for uncompressed tcp slip packets.
1354 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1356 - Hack around deficiency in Ultrix's make.
1358 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1360 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1362 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1364 v3.0 Mon Jun 20 19:23:27 PDT 1994
1366 - Added support for printing tcp option timestamps thanks to
1367 Mark Andrews (mandrews@alias.com).
1369 - Reorganize protocol dumpers to take const pointers to packets so they
1370 never change the contents (i.e., they used to do endian conversions
1371 in place). Previously, whenever more than one pass was taken over
1372 the packet, the packet contents would be dumped incorrectly (i.e.,
1373 the output form -x would be wrong on little endian machines because
1374 the protocol dumpers would modify the data). Thanks to Charles Hannum
1375 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1377 - Added support for decnet protocol dumping thanks to Jeff Mogul
1380 - Fix bug that caused length of packet to be incorrectly printed
1381 (off by ether header size) for unknown ethernet types thanks
1382 to Greg Miller (gmiller@kayak.mitre.org).
1384 - Added support for IPX protocol dumping thanks to Brad Parker
1387 - Added check to verify IP header checksum under -v thanks to
1388 Brad Parker (brad@fcr.com).
1390 - Move packet capture code to new libpcap library (which is
1391 packaged separately).
1393 - Prototype everything and assume an ansi compiler.
1395 - print-arp.c: Print hardware ethernet addresses if they're not
1398 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1399 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1401 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1404 - print-icmp.c: Byte swap netmask before printing. Thanks to
1405 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1407 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1408 By default, only the inner packet is dumped, appended with the token
1409 "(encap)". Under -v, both the inner and output packets are dumped
1410 (on the same line). Note that the filter applies to the original packet,
1411 not the encapsulated packet. So if you run tcpdump on a net with an
1412 IP Multicast tunnel, you cannot filter out the datagrams using the
1413 conventional syntax. (You can filter away all the ip-in-ip traffic
1414 with "not ip proto 4".)
1416 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1417 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1419 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1421 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1422 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1423 Add && and || operators
1425 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1427 - Fix bug with -c flag.
1429 v2.2 Fri May 22 17:19:41 PDT 1992
1431 - savefile.c: Remove hack that shouldn't have been exported. Add
1434 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1435 matches non-echo/reply ICMP packets.
1437 - Many improvements to filter code optimizer.
1439 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1440 so that protocol qualifications are allowed. For example, "ip broadcast"
1441 and "ether multicast" are valid filters.
1443 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1444 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1445 patches to netinet/if_loop.c.
1447 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1448 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1450 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1452 v2.1 Tue Jan 28 11:00:14 PST 1992
1454 - Internal release (never publicly exported).
1456 v2.0.1 Sun Jan 26 21:10:10 PDT
1458 - Various byte ordering fixes.
1460 - Add truncation checks.
1462 - inet.c: Support BSD style SIOCGIFCONF.
1464 - nametoaddr.c: Handle multi addresses for single host.
1466 - optimize.c: Rewritten.
1468 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1471 - print-atal.c: Fix an alignment bug (thanks to
1472 stanonik@nprdc.navy.mil) Add missing printf() argument.
1474 - print-bootp.c: First attempt at decoding the vendor buffer.
1476 - print-domain.c: Fix truncation checks.
1478 - print-icmp.c: Calculate length of packets from the ip header.
1480 - print-ip.c: Print frag id in decimal (so it's easier to match up
1481 with non-frags). Add support for ospf, egp and igmp.
1483 - print-nfs.c: Lots of changes.
1485 - print-ntp.c: Make some verbose output depend on -v.
1487 - print-snmp.c: New version from John LoVerso.
1489 - print-tcp.c: Print rfc1072 tcp options.
1491 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1492 (microseconds) worth of precision. Fix uid bugs.
1494 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1495 With this option, you can create an architecture independent binary
1496 trace file in real time, without the overhead of the packet printer.
1497 At a later time, the packets can be filtered (again) and printed.
1499 - BSD is supported. You must have BPF in your kernel.
1500 Since the filtering is now done in the kernel, fewer packets are
1501 dropped. In fact, with BPF and the packet dumper option, a measly
1502 Sun 3/50 can keep up with a busy network.
1504 - Compressed SLIP packets can now be dumped, provided you use our
1505 SLIP software and BPF. These packets are dumped as any other IP
1506 packet; the compressed headers are dumped with the '-e' option.
1508 - Machines with little-endian byte ordering are supported (thanks to
1511 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1513 - IBM RT and Stanford Enetfilter support has been added by
1514 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1515 both the vanilla Enetfilter interface, and the extended interface
1516 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1518 - TFTP packets are now printed (requests only).
1520 - BOOTP packets are now printed.
1522 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1524 - Sparc architectures, including the Sparcstation-1, are now
1525 supported thanks to Steve McCanne and Craig Leres.
1527 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1528 University (micky@cunixc.cc.columbia.edu).
1530 - IP options are now printed.
1532 - RIP packets are now printed.
1534 - There's a -v flag that prints out more information than the
1535 default (e.g., it will enable printing of IP ttl, tos and id)
1536 and -q flag that prints out less (e.g., it will disable
1537 interpretation of AppleTalk-in-UDP).
1539 - The grammar has undergone substantial changes (if you have an
1540 earlier version of tcpdump, you should re-read the manual
1543 The most useful change is the addition of an expression
1544 syntax that lets you filter on arbitrary fields or values in the
1545 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1546 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1549 The most painful change is that concatenation no longer means
1550 "and" -- e.g., you have to say "host foo and port bar" instead
1551 of "host foo port bar". The up side to this down is that
1552 repeated qualifiers can be omitted, making most filter
1553 expressions shorter. E.g., you can now say "ip host foo and
1554 (bar or baz)" to look at ip traffic between hosts foo and bar or
1555 between hosts foo and baz. [The old way of saying this was "ip
1556 host foo and (ip host bar or ip host baz)".]
1558 v2.0 Sun Jan 13 12:20:40 PST 1991
1560 - Initial public release.
