1247  cache variable name). Thanks to John Hawkinson.
1248
1249- Add a local autoconf macro to check for types; the autoconf version
1250  is broken (it uses grep instead of actually compiling a code fragment).
1251
1252- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
1253  formats.
1254
1255- Extend OSF ip header workaround to versions 1 and 2.

1257- Fix some signed problems in the nfs printer. As reported by David
1258  Sacerdote (davids@silence.secnet.com)
1259
1260- Detect group wheel and use it as the default since BSD/OS' install

1302  Bill Fenner (fenner@parc.xerox.com)
1303
1304- Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
1305
1306- Fix dvmrp printer truncation checks and add a dvmrp probe printer.
1307  Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1308
1309- Rewrite ospf printer to improve truncation checks.
1310
1311- Don't parse tcp options past the EOL. As noted by David Sacerdote
1312  (davids@secnet.com). Also, check tcp options to make sure they ar
1313  actually in the tcp header (in addition to the normal truncation
1314  checks). Fix the SACK code to print the N blocks (instead of the
1315  first block N times).
1316
1317- Don't say really small UDP packets are truncated just because they
1318  aren't big enough to be a RPC. As noted by David Sacerdote.
1319

1339- Use autoconf's idea of the top level directory in install targets.
1340  Thanks to John Hawkinson.
1341
1342- Avoid infinite loop in tcp options printing code. Thanks to Jeffrey
1343  Mogul (mogul@pa.dec.com)
1344
1345- Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
1346  Thanks to John Hawkinson.
1347
1348- Added some more packet truncation checks.
1349
1350- On systems that have it, use sigset() instead of signal() since

1352
1353- Fixed some more alignment problems on the alpha.
1354
1355- Add code to massage unprintable characters in the domain and ipx

1403  types.
1404
1405- Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
1406
1407- Added T/TCP options printing. As suggested by Richard Stevens

1411  accesses.
1412
1413v3.1 Thu Jun 13 20:59:32 PDT 1996
1414
1415- Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
1416  and bind (as suggested by Charles Hannum).
1417
1418- Port to GNU autoconf.
1419
1420- Add support for printing DVMRP and PIM traffic thanks to

1437
1438- Check return status from malloc/calloc/etc.
1439
1440- Check return status from pcap_loop() so we can print an error and
1441  exit with a bad status if there were problems.
1442
1443- Bail if ip option length is <= 0. Resulted from a bug report from
1444  Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).
1445
1446- Print out a little more information for sun rpc packets.
1447
1448- Add support for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu).
1449
1450- Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were
1451  wrong on little endian machines).
1452
1453- Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
1454  (crawdad@fnal.gov).
1455

1477
1478- Include time.h when SVR4 is defined to avoid problems under Solaris
1479  2.3.
1480
1481- Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1482  strings, not the local buffer. Thanks to Stefan Petri
1483  (petri@ibr.cs.tu-bs.de).
1484
1485- Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1486  that the selected value was not used. Thanks to Pascal Hennequin
1487  (Pascal.Hennequin@hugo.int-evry.fr).
1488
1489- Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1490
1491- BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1492
1493v3.0.3 Sun Oct  1 18:35:00 GMT 1995
1494
1495- Although there never was a 3.0.3 release, the linux boys cleverly
1496  "released" one in late 1995.
1497
1498v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1499
1500- Change configuration to not use gcc v2 flags with gcc v1.
1501
1502- Redo gmt2local() so that it works under BSDI (which seems to return
1503  an empty timezone struct from gettimeofday()). Based on report from
1504  Terry Kennedy (terry@spcvxa.spc.edu).
1505
1506- Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1507  on report from Mark Andrews (mandrews@alias.com).
1508
1509- Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1510  Orth (ro@techfak.uni-bielefeld.de).
1511
1512- Fixed printout of connection id for uncompressed tcp slip packets.
1513  Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1514
1515- Hack around deficiency in Ultrix's make.
1516
1517- Add ETHERTYPE_TRAIL define which is missing from irix5.
1518

1520
1521- Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1522
1523v3.0 Mon Jun 20 19:23:27 PDT 1994
1524
1525- Added support for printing tcp option timestamps thanks to
1526  Mark Andrews (mandrews@alias.com).
1527
1528- Reorganize protocol dumpers to take const pointers to packets so they
1529  never change the contents (i.e., they used to do endian conversions
1530  in place).  Previously, whenever more than one pass was taken over
1531  the packet, the packet contents would be dumped incorrectly (i.e.,
1532  the output form -x would be wrong on little endian machines because
1533  the protocol dumpers would modify the data).  Thanks to Charles Hannum
1534  (mycroft@gnu.ai.mit.edu) for reporting this problem.
1535
1536- Added support for decnet protocol dumping thanks to Jeff Mogul
1537  (mogul@pa.dec.com).
1538
1539- Fix bug that caused length of packet to be incorrectly printed
1540  (off by ether header size) for unknown ethernet types thanks
1541  to Greg Miller (gmiller@kayak.mitre.org).
1542
1543- Added support for IPX protocol dumping thanks to Brad Parker
1544  (brad@fcr.com).
1545
1546- Added check to verify IP header checksum under -v thanks to
1547  Brad Parker (brad@fcr.com).
1548
1549- Move packet capture code to new libpcap library (which is
1550  packaged separately).
1551
1552- Prototype everything and assume an ansi compiler.
1553
1554- print-arp.c: Print hardware ethernet addresses if they're not
1555  what we expect.
1556
1557- print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1558  Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1559
1560- print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1561  (mogul@pa.dec.com).
1562
1563- print-icmp.c: Byte swap netmask before printing. Thanks to
1564  Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1565
1566- print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1567  By default, only the inner packet is dumped, appended with the token
1568  "(encap)".  Under -v, both the inner and output packets are dumped
1569  (on the same line).  Note that the filter applies to the original packet,
1570  not the encapsulated packet.  So if you run tcpdump on a net with an
1571  IP Multicast tunnel, you cannot filter out the datagrams using the
1572  conventional syntax.  (You can filter away all the ip-in-ip traffic
1573  with "not ip proto 4".)
1574
1575- print-nfs.c: Keep pending rpc's in circular table. Add generic
1576  nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1577
1578- print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1579
1580- tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1581  (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1582  Add && and || operators
1583
1584v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1585
1586- Fix bug with -c flag.
1587
1588v2.2 Fri May 22 17:19:41 PDT 1992
1589
1590- savefile.c: Remove hack that shouldn't have been exported. Add
1591  truncate checks.
1592
1593- Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
1594  matches non-echo/reply ICMP packets.
1595
1596- Many improvements to filter code optimizer.
1597
1598- Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1599  so that protocol qualifications are allowed. For example, "ip broadcast"
1600  and "ether multicast" are valid filters.
1601
1602- Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1603  Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1604  patches to netinet/if_loop.c.
1605
1606- Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1607  Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1608
1609- Added EGP and OSPF printers, thanks to Jeffrey Honig.

1624
1625- optimize.c: Rewritten.
1626
1627- pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1628  for broadcast nets.
1629
1630- print-atal.c: Fix an alignment bug (thanks to
1631  stanonik@nprdc.navy.mil) Add missing printf() argument.
1632
1633- print-bootp.c: First attempt at decoding the vendor buffer.
1634
1635- print-domain.c: Fix truncation checks.
1636
1637- print-icmp.c: Calculate length of packets from the ip header.
1638
1639- print-ip.c: Print frag id in decimal (so it's easier to match up
1640  with non-frags). Add support for ospf, egp and igmp.
1641
1642- print-nfs.c: Lots of changes.
1643
1644- print-ntp.c: Make some verbose output depend on -v.
1645
1646- print-snmp.c: New version from John LoVerso.
1647
1648- print-tcp.c: Print rfc1072 tcp options.
1649
1650- tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1651  (microseconds) worth of precision. Fix uid bugs.
1652
1653- A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1654  With this option, you can create an architecture independent binary
1655  trace file in real time, without the overhead of the packet printer.
1656  At a later time, the packets can be filtered (again) and printed.
1657
1658- BSD is supported.  You must have BPF in your kernel.
1659  Since the filtering is now done in the kernel, fewer packets are
1660  dropped.  In fact, with BPF and the packet dumper option, a measly
1661  Sun 3/50 can keep up with a busy network.
1662
1663- Compressed SLIP packets can now be dumped, provided you use our
1664  SLIP software and BPF.  These packets are dumped as any other IP
1665  packet; the compressed headers are dumped with the '-e' option.
1666
1667- Machines with little-endian byte ordering are supported (thanks to
1668  Jeff Mogul).
1669
1670- Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1671
1672- IBM RT and Stanford Enetfilter support has been added by
1673  Rayan Zachariassen <rayan@canet.ca>.  Tcpdump has been tested under
1674  both the vanilla Enetfilter interface, and the extended interface
1675  (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1676
1677- TFTP packets are now printed (requests only).
1678
1679- BOOTP packets are now printed.
1680
1681- SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1682
1683- Sparc architectures, including the Sparcstation-1, are now
1684  supported thanks to Steve McCanne and Craig Leres.
1685
1686- SunOS 4 is now supported thanks to Micky Liu of Columbia
1687  University (micky@cunixc.cc.columbia.edu).
1688
1689- IP options are now printed.
1690
1691- RIP packets are now printed.
1692
1693- There's a -v flag that prints out more information than the
1694  default (e.g., it will enable printing of IP ttl, tos and id)
1695  and -q flag that prints out less (e.g., it will disable
1696  interpretation of AppleTalk-in-UDP).
1697
1698- The grammar has undergone substantial changes (if you have an
1699  earlier version of tcpdump, you should re-read the manual
1700  entry).
1701
1702  The most useful change is the addition of an expression
1703  syntax that lets you filter on arbitrary fields or values in the
1704  packet.  E.g., "ip[0] > 0x45" would print only packets with IP
1705  options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1706  packets.
1707
1708  The most painful change is that concatenation no longer means
1709  "and" -- e.g., you have to say "host foo and port bar" instead
1710  of "host foo port bar".  The up side to this down is that
1711  repeated qualifiers can be omitted, making most filter
1712  expressions shorter.  E.g., you can now say "ip host foo and
1713  (bar or baz)" to look at ip traffic between hosts foo and bar or
1714  between hosts foo and baz.  [The old way of saying this was "ip
1715  host foo and (ip host bar or ip host baz)".]
