1264  cache variable name). Thanks to John Hawkinson.
1265
1266- Add a local autoconf macro to check for types; the autoconf version
1267  is broken (it uses grep instead of actually compiling a code fragment).
1268
1269- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
1270  formats.
1271
1272- Extend OSF ip header workaround to versions 1 and 2.

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

1356- Use autoconf's idea of the top level directory in install targets.
1357  Thanks to John Hawkinson.
1358
1359- Avoid infinite loop in tcp options printing code. 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

1370- Fixed some more alignment problems on the alpha.
1371
1372- Add code to massage unprintable characters in the domain and ipx

1402  John Hawkinson.
1403
1404- Fix bugs in the autoconf misaligned accesses code fragment.
1405

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

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

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).

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

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)".]
