1354
1355 - GRE encapsulated packet printer thanks to John Hawkinson
1356   (jhawk@mit.edu)
1357
1358 - Rewrite gmt2local() to avoid problematic os dependencies.
1359
1360 - Suppress nfs truncation message on errors.
1361
1362 - Add missing m4 quoting in AC_LBL_UNALIGNED_ACCESS autoconf macro.
1363   Reported by Joachim Ott (ott@ardala.han.de)
1364
1365 - Enable "ip_hl vs. ip_vhl" workaround for OSF4 too.

1371   (barnett@grymoire.crd.ge.com)
1372
1373 - Fix rip printer to not print one more route than is actually in the
1374   packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
1375   Bill Fenner (fenner@parc.xerox.com)
1376
1377 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
1378
1379 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
1380   Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1381
1382 - Rewrite ospf printer to improve truncation checks.
1383
1384 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1385   (davids@secnet.com). Also, check tcp options to make sure they ar
1386   actually in the tcp header (in addition to the normal truncation
1387   checks). Fix the SACK code to print the N blocks (instead of the
1388   first block N times).
1389
1390 - Don't say really small UDP packets are truncated just because they
1391   aren't big enough to be a RPC. As noted by David Sacerdote.
1392
1393 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1394
1395 - Added rfc1716 icmp codes as suggested by Martin Fredriksson

1412 - Use autoconf's idea of the top level directory in install targets.
1413   Thanks to John Hawkinson.
1414
1415 - Avoid infinite loop in tcp options printing code. Thanks to Jeffrey
1416   Mogul (mogul@pa.dec.com)
1417
1418 - Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
1419   Thanks to John Hawkinson.
1420
1421 - Added some more packet truncation checks.
1422
1423 - On systems that have it, use sigset() instead of signal() since
1424   signal() has different semantics on these systems.
1425
1426 - Fixed some more alignment problems on the alpha.
1427
1428 - Add code to massage unprintable characters in the domain and ipx
1429   printers. Thanks to John Hawkinson.

1447
1448 - Added some ETHERTYPEs missing on some systems.
1449
1450 - Added truncated packet macros and various checks.
1451
1452 - Fixed endian problems with the DECnet printer.
1453

1457 - Fixes for AIX (although this system is not yet supported). Thanks to
1458   John Hawkinson.
1459
1460 - Fix bugs in the autoconf misaligned accesses code fragment.
1461
1462 - Include sys/param.h to get BYTE_ORDER in a few places. Thanks to
1463   Pavlin Ivanov Radoslavov (pavlin@cs.titech.ac.jp)
1464
1465 v3.2 Sun Jun 23 02:28:10 PDT 1996
1466
1467 - Print new icmp unreachable codes as suggested by Martin Fredriksson
1468   (martin@msp.se). Also print code value when unknown for icmp redirect
1469   and time exceeded.
1470
1471 - Fix an alignment endian bug in getname(). Thanks to John Hawkinson.
1472
1473 - Define "new" domain record types if not found in arpa/nameserv.h.
1474   Resulted from a suggestion from John Hawkinson (jhawk@mit.edu). Also
1475   fixed an endian bug when printing mx record and added some new record
1476   types.
1477
1478 - Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
1479
1480 - Added T/TCP options printing. As suggested by Richard Stevens
1481   (rstevens@noao.edu)
1482
1483 - Use autoconf to detect architectures that can't handle misaligned
1484   accesses.
1485
1486 v3.1 Thu Jun 13 20:59:32 PDT 1996
1487
1488 - Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
1489   and bind (as suggested by Charles Hannum).
1490
1491 - Port to GNU autoconf.
1492
1493 - Add support for printing DVMRP and PIM traffic thanks to
1494   Havard Eidnes (Havard.Eidnes@runit.sintef.no).
1495
1496 - Fix AppleTalk, IPX and DECnet byte order problems due to wrong endian
1497   define being referenced. Reported by Terry Kennedy.
1498
1499 - Minor fixes to the man page thanks to Mark Andrews.
1500
1501 - Endian fixes to RTP and vat packet dumpers, thanks to Bruce Mah
1502   (bmah@cs.berkeley.edu).

1505
1506 - Fixed tftp_print() to print the block number for ACKs.
1507
1508 - Document -dd and -ddd. Resulted from a bug report from Charlie Slater
1509   (cslater@imatek.com).
1510
1511 - Check return status from malloc/calloc/etc.
1512
1513 - Check return status from pcap_loop() so we can print an error and
1514   exit with a bad status if there were problems.
1515
1516 - Bail if ip option length is <= 0. Resulted from a bug report from
1517   Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).
1518
1519 - Print out a little more information for sun rpc packets.
1520
1521 - Add support for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu).
1522
1523 - Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were
1524   wrong on little endian machines).
1525
1526 - Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
1527   (crawdad@fnal.gov).
1528
1529 - Fix ntp_print() to not print garbage when the stratum is
1530   "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).
1531
1532 - Rewrote tcp options printer code to check for truncation. Added
1533   selective acknowledgment case.

1536   (jch@bsdi.com)
1537
1538 - Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
1539   octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1540   (toku@dit.co.jp)
1541
1542 - Don't checksum ip header if we don't have all of it. Thanks to John
1543   Hawkinson (jhawk@mit.edu).
1544
1545 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1546   Honig (jhc@bsdi.com)
1547
1548
1549 v3.1a1 Wed May  3 19:21:11 PDT 1995
1550
1551 - Include time.h when SVR4 is defined to avoid problems under Solaris
1552   2.3.
1553
1554 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1555   strings, not the local buffer. Thanks to Stefan Petri
1556   (petri@ibr.cs.tu-bs.de).
1557
1558 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1559   that the selected value was not used. Thanks to Pascal Hennequin
1560   (Pascal.Hennequin@hugo.int-evry.fr).
1561
1562 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1563
1564 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1565
1566 v3.0.3 Sun Oct  1 18:35:00 GMT 1995
1567
1568 - Although there never was a 3.0.3 release, the linux boys cleverly
1569   "released" one in late 1995.
1570
1571 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1572
1573 - Change configuration to not use gcc v2 flags with gcc v1.
1574
1575 - Redo gmt2local() so that it works under BSDI (which seems to return
1576   an empty timezone struct from gettimeofday()). Based on report from
1577   Terry Kennedy (terry@spcvxa.spc.edu).
1578
1579 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1580   on report from Mark Andrews (mandrews@alias.com).
1581
1582 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1583   Orth (ro@techfak.uni-bielefeld.de).
1584
1585 - Fixed printout of connection id for uncompressed tcp slip packets.
1586   Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1587
1588 - Hack around deficiency in Ultrix's make.
1589
1590 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1591
1592 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1593
1594 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1595
1596 v3.0 Mon Jun 20 19:23:27 PDT 1994
1597
1598 - Added support for printing tcp option timestamps thanks to
1599   Mark Andrews (mandrews@alias.com).
1600
1601 - Reorganize protocol dumpers to take const pointers to packets so they
1602   never change the contents (i.e., they used to do endian conversions
1603   in place).  Previously, whenever more than one pass was taken over
1604   the packet, the packet contents would be dumped incorrectly (i.e.,
1605   the output form -x would be wrong on little endian machines because
1606   the protocol dumpers would modify the data).  Thanks to Charles Hannum
1607   (mycroft@gnu.ai.mit.edu) for reporting this problem.
1608
1609 - Added support for decnet protocol dumping thanks to Jeff Mogul
1610   (mogul@pa.dec.com).
1611
1612 - Fix bug that caused length of packet to be incorrectly printed
1613   (off by ether header size) for unknown ethernet types thanks
1614   to Greg Miller (gmiller@kayak.mitre.org).
1615
1616 - Added support for IPX protocol dumping thanks to Brad Parker
1617   (brad@fcr.com).
1618
1619 - Added check to verify IP header checksum under -v thanks to
1620   Brad Parker (brad@fcr.com).
1621
1622 - Move packet capture code to new libpcap library (which is
1623   packaged separately).
1624
1625 - Prototype everything and assume an ansi compiler.
1626
1627 - print-arp.c: Print hardware ethernet addresses if they're not
1628   what we expect.
1629
1630 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1631   Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1632
1633 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1634   (mogul@pa.dec.com).
1635
1636 - print-icmp.c: Byte swap netmask before printing. Thanks to
1637   Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1638
1639 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1640   By default, only the inner packet is dumped, appended with the token
1641   "(encap)".  Under -v, both the inner and output packets are dumped
1642   (on the same line).  Note that the filter applies to the original packet,
1643   not the encapsulated packet.  So if you run tcpdump on a net with an
1644   IP Multicast tunnel, you cannot filter out the datagrams using the
1645   conventional syntax.  (You can filter away all the ip-in-ip traffic
1646   with "not ip proto 4".)
1647
1648 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1649   nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1650
1651 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1652
1653 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1654   (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1655   Add && and || operators
1656
1657 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1658
1659 - Fix bug with -c flag.
1660
1661 v2.2 Fri May 22 17:19:41 PDT 1992
1662
1663 - savefile.c: Remove hack that shouldn't have been exported. Add
1664   truncate checks.
1665
1666 - Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
1667   matches non-echo/reply ICMP packets.
1668
1669 - Many improvements to filter code optimizer.
1670
1671 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1672   so that protocol qualifications are allowed. For example, "ip broadcast"
1673   and "ether multicast" are valid filters.
1674
1675 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1676   Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1677   patches to netinet/if_loop.c.
1678
1679 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1680   Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1681
1682 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1683
1684 v2.1 Tue Jan 28 11:00:14 PST 1992
1685
1686 - Internal release (never publicly exported).
1687
1688 v2.0.1 Sun Jan 26 21:10:10 PDT
1689
1690 - Various byte ordering fixes.
1691
1692 - Add truncation checks.
1693
1694 - inet.c: Support BSD style SIOCGIFCONF.
1695
1696 - nametoaddr.c: Handle multi addresses for single host.
1697
1698 - optimize.c: Rewritten.
1699
1700 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1701   for broadcast nets.
1702
1703 - print-atal.c: Fix an alignment bug (thanks to
1704   stanonik@nprdc.navy.mil) Add missing printf() argument.
1705
1706 - print-bootp.c: First attempt at decoding the vendor buffer.
1707
1708 - print-domain.c: Fix truncation checks.
1709
1710 - print-icmp.c: Calculate length of packets from the ip header.
1711
1712 - print-ip.c: Print frag id in decimal (so it's easier to match up
1713   with non-frags). Add support for ospf, egp and igmp.
1714
1715 - print-nfs.c: Lots of changes.
1716
1717 - print-ntp.c: Make some verbose output depend on -v.
1718
1719 - print-snmp.c: New version from John LoVerso.
1720
1721 - print-tcp.c: Print rfc1072 tcp options.
1722
1723 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1724   (microseconds) worth of precision. Fix uid bugs.
1725
1726 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1727   With this option, you can create an architecture independent binary
1728   trace file in real time, without the overhead of the packet printer.
1729   At a later time, the packets can be filtered (again) and printed.
1730
1731 - BSD is supported.  You must have BPF in your kernel.
1732   Since the filtering is now done in the kernel, fewer packets are
1733   dropped.  In fact, with BPF and the packet dumper option, a measly
1734   Sun 3/50 can keep up with a busy network.
1735
1736 - Compressed SLIP packets can now be dumped, provided you use our
1737   SLIP software and BPF.  These packets are dumped as any other IP
1738   packet; the compressed headers are dumped with the '-e' option.
1739
1740 - Machines with little-endian byte ordering are supported (thanks to
1741   Jeff Mogul).
1742
1743 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1744
1745 - IBM RT and Stanford Enetfilter support has been added by
1746   Rayan Zachariassen <rayan@canet.ca>.  Tcpdump has been tested under
1747   both the vanilla Enetfilter interface, and the extended interface
1748   (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1749
1750 - TFTP packets are now printed (requests only).
1751
1752 - BOOTP packets are now printed.
1753
1754 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1755
1756 - Sparc architectures, including the Sparcstation-1, are now
1757   supported thanks to Steve McCanne and Craig Leres.
1758
1759 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1760   University (micky@cunixc.cc.columbia.edu).
1761
1762 - IP options are now printed.
1763
1764 - RIP packets are now printed.
1765
1766 - There's a -v flag that prints out more information than the
1767   default (e.g., it will enable printing of IP ttl, tos and id)
1768   and -q flag that prints out less (e.g., it will disable
1769   interpretation of AppleTalk-in-UDP).
1770
1771 - The grammar has undergone substantial changes (if you have an
1772   earlier version of tcpdump, you should re-read the manual
1773   entry).
1774
1775   The most useful change is the addition of an expression
1776   syntax that lets you filter on arbitrary fields or values in the
1777   packet.  E.g., "ip[0] > 0x45" would print only packets with IP
1778   options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1779   packets.
1780
1781   The most painful change is that concatenation no longer means
1782   "and" -- e.g., you have to say "host foo and port bar" instead
1783   of "host foo port bar".  The up side to this down is that
1784   repeated qualifiers can be omitted, making most filter
1785   expressions shorter.  E.g., you can now say "ip host foo and
1786   (bar or baz)" to look at ip traffic between hosts foo and bar or
1787   between hosts foo and baz.  [The old way of saying this was "ip
1788   host foo and (ip host bar or ip host baz)".]
1789
1790 v2.0 Sun Jan 13 12:20:40 PST 1991
1791
1792 - Initial public release.
