Also, check tcp options to make sure they ar 1172 actually in the tcp header (in addition to the normal truncation 1173 checks). Fix the SACK code to print the N blocks (instead of the 1174 first block N times). 1175 1176- Don't say really small UDP packets are truncated just because they 1177 aren't big enough to be a RPC. As noted by David Sacerdote. 1178 1179v3.2.1 Sun Jul 14 03:02:26 PDT 1996 1180 1181- Added rfc1716 icmp codes as suggested by Martin Fredriksson 1182 (martin@msp.se) 1183 1184- Print mtu for icmp unreach need frag packets.

Thanks to 1249 Pavlin Ivanov Radoslavov (pavlin@cs.titech.ac.jp) 1250 1251v3.2 Sun Jun 23 02:28:10 PDT 1996 1252 1253- Print new icmp unreachable codes as suggested by Martin Fredriksson 1254 (martin@msp.se). Also print code value when unknown for icmp redirect 1255 and time exceeded. 1256 1257- Fix an alignment endian bug in getname(). Thanks to John Hawkinson. 1258 1259- Define "new" domain record types if not found in arpa/nameserv.h. 1260 Resulted from a suggestion from John Hawkinson (jhawk@mit.edu).

Resulted from a bug report from Charlie Slater 1295 (cslater@imatek.com). 1296 1297- Check return status from malloc/calloc/etc. 1298 1299- Check return status from pcap_loop() so we can print an error and 1300 exit with a bad status if there were problems. 1301 1302- Bail if ip option length is <= 0. Resulted from a bug report from 1303 Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au). 1304 1305- Print out a little more information for sun rpc packets. 1306 1307- Add support for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu). 1308 1309- Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were 1310 wrong on little endian machines). 1311 1312- Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford 1313 (crawdad@fnal.gov). 1314 1315- Fix ntp_print() to not print garbage when the stratum is 1316 "unspecified."

Based on report from 1363 Terry Kennedy (terry@spcvxa.spc.edu). 1364 1365- Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based 1366 on report from Mark Andrews (mandrews@alias.com). 1367 1368- Don't pass cc flags to gcc. Resulted from a bug report from Rainer 1369 Orth (ro@techfak.uni-bielefeld.de). 1370 1371- Fixed printout of connection id for uncompressed tcp slip packets. 1372 Resulted from a bug report from Richard Stevens (rstevens@noao.edu). 1373 1374- Hack around deficiency in Ultrix's make. 1375 1376- Add ETHERTYPE_TRAIL define which is missing from irix5. 1377 1378v3.0.1 Wed Aug 31 22:42:26 PDT 1994 1379 1380- Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4. 1381 1382v3.0 Mon Jun 20 19:23:27 PDT 1994 1383 1384- Added support for printing tcp option timestamps thanks to 1385 Mark Andrews (mandrews@alias.com). 1386 1387- Reorganize protocol dumpers to take const pointers to packets so they 1388 never change the contents (i.e., they used to do endian conversions 1389 in place). Previously, whenever more than one pass was taken over 1390 the packet, the packet contents would be dumped incorrectly (i.e., 1391 the output form -x would be wrong on little endian machines because 1392 the protocol dumpers would modify the data). Thanks to Charles Hannum 1393 (mycroft@gnu.ai.mit.edu) for reporting this problem. 1394 1395- Added support for decnet protocol dumping thanks to Jeff Mogul 1396 (mogul@pa.dec.com). 1397 1398- Fix bug that caused length of packet to be incorrectly printed 1399 (off by ether header size) for unknown ethernet types thanks 1400 to Greg Miller (gmiller@kayak.mitre.org). 1401 1402- Added support for IPX protocol dumping thanks to Brad Parker 1403 (brad@fcr.com). 1404 1405- Added check to verify IP header checksum under -v thanks to 1406 Brad Parker (brad@fcr.com). 1407 1408- Move packet capture code to new libpcap library (which is 1409 packaged separately). 1410 1411- Prototype everything and assume an ansi compiler. 1412 1413- print-arp.c: Print hardware ethernet addresses if they're not 1414 what we expect. 1415 1416- print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags. 1417 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com). 1418 1419- print-fddi.c: Improvements. Thanks to Jeffrey Mogul 1420 (mogul@pa.dec.com). 1421 1422- print-icmp.c: Byte swap netmask before printing. Thanks to 1423 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown. 1424 1425- print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets. 1426 By default, only the inner packet is dumped, appended with the token 1427 "(encap)". Under -v, both the inner and output packets are dumped 1428 (on the same line). Note that the filter applies to the original packet, 1429 not the encapsulated packet. So if you run tcpdump on a net with an 1430 IP Multicast tunnel, you cannot filter out the datagrams using the 1431 conventional syntax. (You can filter away all the ip-in-ip traffic 1432 with "not ip proto 4".) 1433 1434- print-nfs.c: Keep pending rpc's in circular table. Add generic 1435 nfs header and remove os dependences. Thanks to Jeffrey Mogul. 1436 1437- print-ospf.c: Improvements. Thanks to Jeffrey Mogul. 1438 1439- tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc" 1440 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords 1441 Add && and || operators 1442 1443v2.2.1 Tue Jun 6 17:57:22 PDT 1992 1444 1445- Fix bug with -c flag. 1446 1447v2.2 Fri May 22 17:19:41 PDT 1992 1448 1449- savefile.c: Remove hack that shouldn't have been exported. Add 1450 truncate checks. 1451 1452- Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0' 1453 matches non-echo/reply ICMP packets. 1454 1455- Many improvements to filter code optimizer. 1456 1457- Added 'multicast' keyword and extended the 'broadcast' keyword can now be 1458 so that protocol qualifications are allowed. For example, "ip broadcast" 1459 and "ether multicast" are valid filters. 1460 1461- Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo'). 1462 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel 1463 patches to netinet/if_loop.c. 1464 1465- Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS. 1466 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs. 1467 1468- Added EGP and OSPF printers, thanks to Jeffrey Honig. 1469 1470v2.1 Tue Jan 28 11:00:14 PST 1992 1471 1472- Internal release (never publicly exported). 1473 1474v2.0.1 Sun Jan 26 21:10:10 PDT 1475 1476- Various byte ordering fixes. 1477 1478- Add truncation checks. 1479 1480- inet.c: Support BSD style SIOCGIFCONF. 1481 1482- nametoaddr.c: Handle multi addresses for single host. 1483 1484- optimize.c: Rewritten. 1485 1486- pcap-bpf.c: don't choke when we get ptraced. only set promiscuous 1487 for broadcast nets. 1488 1489- print-atal.c: Fix an alignment bug (thanks to 1490 stanonik@nprdc.navy.mil) Add missing printf() argument. 1491 1492- print-bootp.c: First attempt at decoding the vendor buffer. 1493 1494- print-domain.c: Fix truncation checks. 1495 1496- print-icmp.c: Calculate length of packets from the ip header. 1497 1498- print-ip.c: Print frag id in decimal (so it's easier to match up 1499 with non-frags). Add support for ospf, egp and igmp. 1500 1501- print-nfs.c: Lots of changes. 1502 1503- print-ntp.c: Make some verbose output depend on -v. 1504 1505- print-snmp.c: New version from John LoVerso. 1506 1507- print-tcp.c: Print rfc1072 tcp options. 1508 1509- tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits 1510 (microseconds) worth of precision. Fix uid bugs. 1511 1512- A packet dumper has been added (thanks to Jeff Mogul of DECWRL). 1513 With this option, you can create an architecture independent binary 1514 trace file in real time, without the overhead of the packet printer. 1515 At a later time, the packets can be filtered (again) and printed. 1516 1517- BSD is supported. You must have BPF in your kernel. 1518 Since the filtering is now done in the kernel, fewer packets are 1519 dropped. In fact, with BPF and the packet dumper option, a measly 1520 Sun 3/50 can keep up with a busy network. 1521 1522- Compressed SLIP packets can now be dumped, provided you use our 1523 SLIP software and BPF. These packets are dumped as any other IP 1524 packet; the compressed headers are dumped with the '-e' option. 1525 1526- Machines with little-endian byte ordering are supported (thanks to 1527 Jeff Mogul). 1528 1529- Ultrix 4.0 is supported (also thanks to Jeff Mogul). 1530 1531- IBM RT and Stanford Enetfilter support has been added by 1532 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under 1533 both the vanilla Enetfilter interface, and the extended interface 1534 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter. 1535 1536- TFTP packets are now printed (requests only). 1537 1538- BOOTP packets are now printed. 1539 1540- SNMP packets are now printed. (thanks to John LoVerso of Xylogics). 1541 1542- Sparc architectures, including the Sparcstation-1, are now 1543 supported thanks to Steve McCanne and Craig Leres. 1544 1545- SunOS 4 is now supported thanks to Micky Liu of Columbia 1546 University (micky@cunixc.cc.columbia.edu). 1547 1548- IP options are now printed. 1549 1550- RIP packets are now printed. 1551 1552- There's a -v flag that prints out more information than the 1553 default (e.g., it will enable printing of IP ttl, tos and id) 1554 and -q flag that prints out less (e.g., it will disable 1555 interpretation of AppleTalk-in-UDP). 1556 1557- The grammar has undergone substantial changes (if you have an 1558 earlier version of tcpdump, you should re-read the manual 1559 entry). 1560 1561 The most useful change is the addition of an expression 1562 syntax that lets you filter on arbitrary fields or values in the 1563 packet. E.g., "ip[0] > 0x45" would print only packets with IP 1564 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN 1565 packets. 1566 1567 The most painful change is that concatenation no longer means 1568 "and" -- e.g., you have to say "host foo and port bar" instead 1569 of "host foo port bar". The up side to this down is that 1570 repeated qualifiers can be omitted, making most filter 1571 expressions shorter. E.g., you can now say "ip host foo and 1572 (bar or baz)" to look at ip traffic between hosts foo and bar or 1573 between hosts foo and baz. [The old way of saying this was "ip 1574 host foo and (ip host bar or ip host baz)".] 1575 1576v2.0 Sun Jan 13 12:20:40 PST 1991 1577 1578- Initial public release. 1579
