Thanks to Bruce Barnett 1315 (barnett@grymoire.crd.ge.com) 1316 1317- Fix rip printer to not print one more route than is actually in the 1318 packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and 1319 Bill Fenner (fenner@parc.xerox.com) 1320 1321- Use autoconf endian detection since BYTE_ORDER isn't defined on all systems. 1322 1323- Fix dvmrp printer truncation checks and add a dvmrp probe printer. 1324 Thanks to Danny J. Mitzel (mitzel@ipsilon.com) 1325 1326- Rewrite ospf printer to improve truncation checks. 1327 1328- Don't parse tcp options past the EOL. As noted by David Sacerdote 1329 (davids@secnet.com). Also, check tcp options to make sure they ar 1330 actually in the tcp header (in addition to the normal truncation 1331 checks). Fix the SACK code to print the N blocks (instead of the 1332 first block N times). 1333 1334- Don't say really small UDP packets are truncated just because they 1335 aren't big enough to be a RPC. As noted by David Sacerdote. 1336 1337v3.2.1 Sun Jul 14 03:02:26 PDT 1996 1338 1339- Added rfc1716 icmp codes as suggested by Martin Fredriksson 1340 (martin@msp.se) 1341 1342- Print mtu for icmp unreach need frag packets.

Thanks to Jeffrey 1360 Mogul (mogul@pa.dec.com) 1361 1362- Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop. 1363 Thanks to John Hawkinson. 1364 1365- Added some more packet truncation checks. 1366 1367- On systems that have it, use sigset() instead of signal() since 1368 signal() has different semantics on these systems. 1369 1370- Fixed some more alignment problems on the alpha. 1371 1372- Add code to massage unprintable characters in the domain and ipx 1373 printers. Thanks to John Hawkinson. 1374 1375- Added explicit netmask support. Thanks to Steve Nuchia 1376 (steve@research.oknet.com) 1377 1378- Add "sca" keyword (for DEC cluster services) as suggested by Terry 1379 Kennedy (terry@spcvxa.spc.edu) 1380 1381- Add "atalk" keyword as suggested by John Hawkinson. 1382 1383- Added an igrp printer. Thanks to Francis Dupont 1384 (francis.dupont@inria.fr) 1385 1386- Print IPX net numbers in hex a la Novell Netware. Thanks to Terry 1387 Kennedy (terry@spcvxa.spc.edu) 1388 1389- Fixed snmp extended tag field parsing bug. Thanks to Pascal Hennequin 1390 (pascal.hennequin@hugo.int-evry.fr) 1391 1392- Added some ETHERTYPEs missing on some systems. 1393 1394- Added truncated packet macros and various checks. 1395 1396- Fixed endian problems with the DECnet printer. 1397 1398- Use $CC when checking gcc version. Thanks to Carl Lindberg 1399 (carl_lindberg@blacksmith.com) 1400 1401- Fixes for AIX (although this system is not yet supported). Thanks to 1402 John Hawkinson. 1403 1404- Fix bugs in the autoconf misaligned accesses code fragment. 1405 1406- Include sys/param.h to get BYTE_ORDER in a few places. Thanks to 1407 Pavlin Ivanov Radoslavov (pavlin@cs.titech.ac.jp) 1408 1409v3.2 Sun Jun 23 02:28:10 PDT 1996 1410 1411- Print new icmp unreachable codes as suggested by Martin Fredriksson 1412 (martin@msp.se). Also print code value when unknown for icmp redirect 1413 and time exceeded. 1414 1415- Fix an alignment endian bug in getname(). Thanks to John Hawkinson. 1416 1417- Define "new" domain record types if not found in arpa/nameserv.h. 1418 Resulted from a suggestion from John Hawkinson (jhawk@mit.edu). Also 1419 fixed an endian bug when printing mx record and added some new record 1420 types. 1421 1422- Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com) 1423 1424- Added T/TCP options printing. As suggested by Richard Stevens 1425 (rstevens@noao.edu) 1426 1427- Use autoconf to detect architectures that can't handle misaligned 1428 accesses. 1429 1430v3.1 Thu Jun 13 20:59:32 PDT 1996 1431 1432- Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd 1433 and bind (as suggested by Charles Hannum). 1434 1435- Port to GNU autoconf. 1436 1437- Add support for printing DVMRP and PIM traffic thanks to 1438 Havard Eidnes (Havard.Eidnes@runit.sintef.no). 1439 1440- Fix AppleTalk, IPX and DECnet byte order problems due to wrong endian 1441 define being referenced. Reported by Terry Kennedy. 1442 1443- Minor fixes to the man page thanks to Mark Andrews. 1444 1445- Endian fixes to RTP and vat packet dumpers, thanks to Bruce Mah 1446 (bmah@cs.berkeley.edu). 1447 1448- Added support for new dns types, thanks to Rainer Orth. 1449 1450- Fixed tftp_print() to print the block number for ACKs. 1451 1452- Document -dd and -ddd. Resulted from a bug report from Charlie Slater 1453 (cslater@imatek.com). 1454 1455- Check return status from malloc/calloc/etc. 1456 1457- Check return status from pcap_loop() so we can print an error and 1458 exit with a bad status if there were problems. 1459 1460- Bail if ip option length is <= 0. Resulted from a bug report from 1461 Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au). 1462 1463- Print out a little more information for sun rpc packets. 1464 1465- Add support for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu). 1466 1467- Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were 1468 wrong on little endian machines). 1469 1470- Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford 1471 (crawdad@fnal.gov). 1472 1473- Fix ntp_print() to not print garbage when the stratum is 1474 "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com). 1475 1476- Rewrote tcp options printer code to check for truncation. Added 1477 selective acknowledgment case. 1478 1479- Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig 1480 (jch@bsdi.com) 1481 1482- Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one 1483 octet for the sa_family member. Thanks to Yoshitaka Tokugawa 1484 (toku@dit.co.jp) 1485 1486- Don't checksum ip header if we don't have all of it. Thanks to John 1487 Hawkinson (jhawk@mit.edu). 1488 1489- Print out hostnames if possible in egp printer. Thanks to Jeffrey 1490 Honig (jhc@bsdi.com) 1491 1492 1493v3.1a1 Wed May 3 19:21:11 PDT 1995 1494 1495- Include time.h when SVR4 is defined to avoid problems under Solaris 1496 2.3. 1497 1498- Fix etheraddr_string() in the ETHER_SERVICE to return the saved 1499 strings, not the local buffer. Thanks to Stefan Petri 1500 (petri@ibr.cs.tu-bs.de). 1501 1502- Detect when pcap raises the snaplen (e.g. with snit). Print a warning 1503 that the selected value was not used. Thanks to Pascal Hennequin 1504 (Pascal.Hennequin@hugo.int-evry.fr). 1505 1506- Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin. 1507 1508- BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu). 1509 1510v3.0.3 Sun Oct 1 18:35:00 GMT 1995 1511 1512- Although there never was a 3.0.3 release, the linux boys cleverly 1513 "released" one in late 1995. 1514 1515v3.0.2 Thu Apr 20 21:28:16 PDT 1995 1516 1517- Change configuration to not use gcc v2 flags with gcc v1. 1518 1519- Redo gmt2local() so that it works under BSDI (which seems to return 1520 an empty timezone struct from gettimeofday()). Based on report from 1521 Terry Kennedy (terry@spcvxa.spc.edu). 1522 1523- Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based 1524 on report from Mark Andrews (mandrews@alias.com). 1525 1526- Don't pass cc flags to gcc. Resulted from a bug report from Rainer 1527 Orth (ro@techfak.uni-bielefeld.de). 1528 1529- Fixed printout of connection id for uncompressed tcp slip packets. 1530 Resulted from a bug report from Richard Stevens (rstevens@noao.edu). 1531 1532- Hack around deficiency in Ultrix's make. 1533 1534- Add ETHERTYPE_TRAIL define which is missing from irix5. 1535 1536v3.0.1 Wed Aug 31 22:42:26 PDT 1994 1537 1538- Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4. 1539 1540v3.0 Mon Jun 20 19:23:27 PDT 1994 1541 1542- Added support for printing tcp option timestamps thanks to 1543 Mark Andrews (mandrews@alias.com). 1544 1545- Reorganize protocol dumpers to take const pointers to packets so they 1546 never change the contents (i.e., they used to do endian conversions 1547 in place). Previously, whenever more than one pass was taken over 1548 the packet, the packet contents would be dumped incorrectly (i.e., 1549 the output form -x would be wrong on little endian machines because 1550 the protocol dumpers would modify the data). Thanks to Charles Hannum 1551 (mycroft@gnu.ai.mit.edu) for reporting this problem. 1552 1553- Added support for decnet protocol dumping thanks to Jeff Mogul 1554 (mogul@pa.dec.com). 1555 1556- Fix bug that caused length of packet to be incorrectly printed 1557 (off by ether header size) for unknown ethernet types thanks 1558 to Greg Miller (gmiller@kayak.mitre.org). 1559 1560- Added support for IPX protocol dumping thanks to Brad Parker 1561 (brad@fcr.com). 1562 1563- Added check to verify IP header checksum under -v thanks to 1564 Brad Parker (brad@fcr.com). 1565 1566- Move packet capture code to new libpcap library (which is 1567 packaged separately). 1568 1569- Prototype everything and assume an ansi compiler. 1570 1571- print-arp.c: Print hardware ethernet addresses if they're not 1572 what we expect. 1573 1574- print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags. 1575 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com). 1576 1577- print-fddi.c: Improvements. Thanks to Jeffrey Mogul 1578 (mogul@pa.dec.com). 1579 1580- print-icmp.c: Byte swap netmask before printing. Thanks to 1581 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown. 1582 1583- print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets. 1584 By default, only the inner packet is dumped, appended with the token 1585 "(encap)". Under -v, both the inner and output packets are dumped 1586 (on the same line). Note that the filter applies to the original packet, 1587 not the encapsulated packet. So if you run tcpdump on a net with an 1588 IP Multicast tunnel, you cannot filter out the datagrams using the 1589 conventional syntax. (You can filter away all the ip-in-ip traffic 1590 with "not ip proto 4".) 1591 1592- print-nfs.c: Keep pending rpc's in circular table. Add generic 1593 nfs header and remove os dependences. Thanks to Jeffrey Mogul. 1594 1595- print-ospf.c: Improvements. Thanks to Jeffrey Mogul. 1596 1597- tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc" 1598 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords 1599 Add && and || operators 1600 1601v2.2.1 Tue Jun 6 17:57:22 PDT 1992 1602 1603- Fix bug with -c flag. 1604 1605v2.2 Fri May 22 17:19:41 PDT 1992 1606 1607- savefile.c: Remove hack that shouldn't have been exported. Add 1608 truncate checks. 1609 1610- Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0' 1611 matches non-echo/reply ICMP packets. 1612 1613- Many improvements to filter code optimizer. 1614 1615- Added 'multicast' keyword and extended the 'broadcast' keyword can now be 1616 so that protocol qualifications are allowed. For example, "ip broadcast" 1617 and "ether multicast" are valid filters. 1618 1619- Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo'). 1620 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel 1621 patches to netinet/if_loop.c. 1622 1623- Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS. 1624 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs. 1625 1626- Added EGP and OSPF printers, thanks to Jeffrey Honig. 1627 1628v2.1 Tue Jan 28 11:00:14 PST 1992 1629 1630- Internal release (never publicly exported). 1631 1632v2.0.1 Sun Jan 26 21:10:10 PDT 1633 1634- Various byte ordering fixes. 1635 1636- Add truncation checks. 1637 1638- inet.c: Support BSD style SIOCGIFCONF. 1639 1640- nametoaddr.c: Handle multi addresses for single host. 1641 1642- optimize.c: Rewritten. 1643 1644- pcap-bpf.c: don't choke when we get ptraced. only set promiscuous 1645 for broadcast nets. 1646 1647- print-atal.c: Fix an alignment bug (thanks to 1648 stanonik@nprdc.navy.mil) Add missing printf() argument. 1649 1650- print-bootp.c: First attempt at decoding the vendor buffer. 1651 1652- print-domain.c: Fix truncation checks. 1653 1654- print-icmp.c: Calculate length of packets from the ip header. 1655 1656- print-ip.c: Print frag id in decimal (so it's easier to match up 1657 with non-frags). Add support for ospf, egp and igmp. 1658 1659- print-nfs.c: Lots of changes. 1660 1661- print-ntp.c: Make some verbose output depend on -v. 1662 1663- print-snmp.c: New version from John LoVerso. 1664 1665- print-tcp.c: Print rfc1072 tcp options. 1666 1667- tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits 1668 (microseconds) worth of precision. Fix uid bugs. 1669 1670- A packet dumper has been added (thanks to Jeff Mogul of DECWRL). 1671 With this option, you can create an architecture independent binary 1672 trace file in real time, without the overhead of the packet printer. 1673 At a later time, the packets can be filtered (again) and printed. 1674 1675- BSD is supported. You must have BPF in your kernel. 1676 Since the filtering is now done in the kernel, fewer packets are 1677 dropped. In fact, with BPF and the packet dumper option, a measly 1678 Sun 3/50 can keep up with a busy network. 1679 1680- Compressed SLIP packets can now be dumped, provided you use our 1681 SLIP software and BPF. These packets are dumped as any other IP 1682 packet; the compressed headers are dumped with the '-e' option. 1683 1684- Machines with little-endian byte ordering are supported (thanks to 1685 Jeff Mogul). 1686 1687- Ultrix 4.0 is supported (also thanks to Jeff Mogul). 1688 1689- IBM RT and Stanford Enetfilter support has been added by 1690 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under 1691 both the vanilla Enetfilter interface, and the extended interface 1692 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter. 1693 1694- TFTP packets are now printed (requests only). 1695 1696- BOOTP packets are now printed. 1697 1698- SNMP packets are now printed. (thanks to John LoVerso of Xylogics). 1699 1700- Sparc architectures, including the Sparcstation-1, are now 1701 supported thanks to Steve McCanne and Craig Leres. 1702 1703- SunOS 4 is now supported thanks to Micky Liu of Columbia 1704 University (micky@cunixc.cc.columbia.edu). 1705 1706- IP options are now printed. 1707 1708- RIP packets are now printed. 1709 1710- There's a -v flag that prints out more information than the 1711 default (e.g., it will enable printing of IP ttl, tos and id) 1712 and -q flag that prints out less (e.g., it will disable 1713 interpretation of AppleTalk-in-UDP). 1714 1715- The grammar has undergone substantial changes (if you have an 1716 earlier version of tcpdump, you should re-read the manual 1717 entry). 1718 1719 The most useful change is the addition of an expression 1720 syntax that lets you filter on arbitrary fields or values in the 1721 packet. E.g., "ip[0] > 0x45" would print only packets with IP 1722 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN 1723 packets. 1724 1725 The most painful change is that concatenation no longer means 1726 "and" -- e.g., you have to say "host foo and port bar" instead 1727 of "host foo port bar". The up side to this down is that 1728 repeated qualifiers can be omitted, making most filter 1729 expressions shorter. E.g., you can now say "ip host foo and 1730 (bar or baz)" to look at ip traffic between hosts foo and bar or 1731 between hosts foo and baz. [The old way of saying this was "ip 1732 host foo and (ip host bar or ip host baz)".] 1733 1734v2.0 Sun Jan 13 12:20:40 PST 1991 1735 1736- Initial public release. 1737
