1247  (Pascal.Hennequin@hugo.int-evry.fr).
1248
1249- Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1250
1251- BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1252
1253v3.0.3 Sun Oct  1 18:35:00 GMT 1995
1254
1255- Although there never was a 3.0.3 release, the linux boys cleverly
1256  "released" one in late 1995.
1257
1258v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1259
1260- Change configuration to not use gcc v2 flags with gcc v1.
1261
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).
1265
1266- Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1267  on report from Mark Andrews (mandrews@alias.com).
1268
1269- Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1270  Orth (ro@techfak.uni-bielefeld.de).
1271
1272- Fixed printout of connection id for uncompressed tcp slip packets.
1273  Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1274
1275- Hack around deficiency in Ultrix's make.
1276
1277- Add ETHERTYPE_TRAIL define which is missing from irix5.
1278
1279v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1280
1281- Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1282
1283v3.0 Mon Jun 20 19:23:27 PDT 1994
1284
1285- Added support for printing tcp option timestamps thanks to
1286  Mark Andrews (mandrews@alias.com).
1287
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.
1295
1296- Added support for decnet protocol dumping thanks to Jeff Mogul
1297  (mogul@pa.dec.com).
1298
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).
1302
1303- Added support for IPX protocol dumping thanks to Brad Parker
1304  (brad@fcr.com).
1305
1306- Added check to verify IP header checksum under -v thanks to
1307  Brad Parker (brad@fcr.com).
1308
1309- Move packet capture code to new libpcap library (which is
1310  packaged separately).
1311
1312- Prototype everything and assume an ansi compiler.
1313
1314- print-arp.c: Print hardware ethernet addresses if they're not
1315  what we expect.
1316
1317- print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1318  Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1319
1320- print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1321  (mogul@pa.dec.com).
1322
1323- print-icmp.c: Byte swap netmask before printing. Thanks to
1324  Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1325
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".)
1334
1335- print-nfs.c: Keep pending rpc's in circular table. Add generic
1336  nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1337
1338- print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1339
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
1343
1344v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1345
1346- Fix bug with -c flag.
1347
1348v2.2 Fri May 22 17:19:41 PDT 1992
1349
1350- savefile.c: Remove hack that shouldn't have been exported. Add
1351  truncate checks.
1352
1353- Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
1354  matches non-echo/reply ICMP packets.
1355
1356- Many improvements to filter code optimizer.
1357
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.
1361
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.
1365
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.
1368
1369- Added EGP and OSPF printers, thanks to Jeffrey Honig.
1370
1371v2.1 Tue Jan 28 11:00:14 PST 1992
1372
1373- Internal release (never publically exported).
1374
1375v2.0.1 Sun Jan 26 21:10:10 PDT
1376
1377- Various byte ordering fixes.
1378
1379- Add truncation checks.
1380
1381- inet.c: Support BSD style SIOCGIFCONF.
1382
1383- nametoaddr.c: Handle multi addresses for single host.
1384
1385- optimize.c: Rewritten.
1386
1387- pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1388  for broadcast nets.
1389
1390- print-atal.c: Fix an alignment bug (thanks to
1391  stanonik@nprdc.navy.mil) Add missing printf() argument.
1392
1393- print-bootp.c: First attempt at decoding the vendor buffer.
1394
1395- print-domain.c: Fix truncation checks.
1396
1397- print-icmp.c: Calculate length of packets from the ip header.
1398
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.
1401
1402- print-nfs.c: Lots of changes.
1403
1404- print-ntp.c: Make some verbose output depend on -v.
1405
1406- print-snmp.c: New version from John LoVerso.
1407
1408- print-tcp.c: Print rfc1072 tcp options.
1409
1410- tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1411  (microseconds) worth of precision. Fix uid bugs.
1412
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.
1417
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.
1422
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.
1426
1427- Machines with little-endian byte ordering are supported (thanks to
1428  Jeff Mogul).
1429
1430- Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1431
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.
1436
1437- TFTP packets are now printed (requests only).
1438
1439- BOOTP packets are now printed.
1440
1441- SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1442
1443- Sparc architectures, including the Sparcstation-1, are now
1444  supported thanks to Steve McCanne and Craig Leres.
1445
1446- SunOS 4 is now supported thanks to Micky Liu of Columbia
1447  University (micky@cunixc.cc.columbia.edu).
1448
1449- IP options are now printed.
1450
1451- RIP packets are now printed.
1452
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).
1457
1458- The grammar has undergone substantial changes (if you have an
1459  earlier version of tcpdump, you should re-read the manual
1460  entry).
1461
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
1466  packets.
1467
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)".]
1476
1477v2.0 Sun Jan 13 12:20:40 PST 1991
1478
1479- Initial public release.
