1384   Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1385
1386 - Rewrite ospf printer to improve truncation checks.
1387
1388 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1389   (davids@secnet.com). Also, check tcp options to make sure they ar
1390   actually in the tcp header (in addition to the normal truncation
1391   checks). Fix the SACK code to print the N blocks (instead of the
1392   first block N times).
1393
1394 - Don't say really small UDP packets are truncated just because they
1395   aren't big enough to be a RPC. As noted by David Sacerdote.
1396

1420   Mogul (mogul@pa.dec.com)
1421
1422 - Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
1423   Thanks to John Hawkinson.
1424
1425 - Added some more packet truncation checks.
1426
1427 - On systems that have it, use sigset() instead of signal() since

1429
1430 - Fixed some more alignment problems on the alpha.
1431

1468
1469 v3.2 Sun Jun 23 02:28:10 PDT 1996
1470
1471 - Print new icmp unreachable codes as suggested by Martin Fredriksson
1472   (martin@msp.se). Also print code value when unknown for icmp redirect
1473   and time exceeded.
1474
1475 - Fix an alignment endian bug in getname(). Thanks to John Hawkinson.
1476
1477 - Define "new" domain record types if not found in arpa/nameserv.h.

1480   types.
1481
1482 - Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
1483
1484 - Added T/TCP options printing. As suggested by Richard Stevens
1485   (rstevens@noao.edu)
1486
1487 - Use autoconf to detect architectures that can't handle misaligned
1488   accesses.
1489
1490 v3.1 Thu Jun 13 20:59:32 PDT 1996
1491
1492 - Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
1493   and bind (as suggested by Charles Hannum).

1495 - Port to GNU autoconf.
1496
1497 - Add support for printing DVMRP and PIM traffic thanks to
1498   Havard Eidnes (Havard.Eidnes@runit.sintef.no).
1499
1500 - Fix AppleTalk, IPX and DECnet byte order problems due to wrong endian
1501   define being referenced. Reported by Terry Kennedy.

1513   (cslater@imatek.com).
1514
1515 - Check return status from malloc/calloc/etc.
1516
1517 - Check return status from pcap_loop() so we can print an error and
1518   exit with a bad status if there were problems.
1519
1520 - Bail if ip option length is <= 0. Resulted from a bug report from
1521   Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).
1522
1523 - Print out a little more information for sun rpc packets.
1524
1525 - Add support for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu).
1526
1527 - Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were
1528   wrong on little endian machines).
1529
1530 - Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
1531   (crawdad@fnal.gov).
1532
1533 - Fix ntp_print() to not print garbage when the stratum is
1534   "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).

1543   octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1544   (toku@dit.co.jp)
1545
1546 - Don't checksum ip header if we don't have all of it. Thanks to John
1547   Hawkinson (jhawk@mit.edu).
1548
1549 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1550   Honig (jhc@bsdi.com)
1551
1552
1553 v3.1a1 Wed May  3 19:21:11 PDT 1995
1554
1555 - Include time.h when SVR4 is defined to avoid problems under Solaris
1556   2.3.
1557
1558 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1559   strings, not the local buffer. Thanks to Stefan Petri
1560   (petri@ibr.cs.tu-bs.de).
1561
1562 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1563   that the selected value was not used. Thanks to Pascal Hennequin
1564   (Pascal.Hennequin@hugo.int-evry.fr).
1565
1566 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1567
1568 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1569
1570 v3.0.3 Sun Oct  1 18:35:00 GMT 1995
1571
1572 - Although there never was a 3.0.3 release, the linux boys cleverly
1573   "released" one in late 1995.
1574
1575 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1576
1577 - Change configuration to not use gcc v2 flags with gcc v1.
1578
1579 - Redo gmt2local() so that it works under BSDI (which seems to return
1580   an empty timezone struct from gettimeofday()). Based on report from
1581   Terry Kennedy (terry@spcvxa.spc.edu).
1582
1583 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1584   on report from Mark Andrews (mandrews@alias.com).
1585
1586 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1587   Orth (ro@techfak.uni-bielefeld.de).
1588
1589 - Fixed printout of connection id for uncompressed tcp slip packets.
1590   Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1591
1592 - Hack around deficiency in Ultrix's make.
1593
1594 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1595
1596 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1597
1598 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1599
1600 v3.0 Mon Jun 20 19:23:27 PDT 1994
1601
1602 - Added support for printing tcp option timestamps thanks to
1603   Mark Andrews (mandrews@alias.com).
1604
1605 - Reorganize protocol dumpers to take const pointers to packets so they
1606   never change the contents (i.e., they used to do endian conversions
1607   in place).  Previously, whenever more than one pass was taken over
1608   the packet, the packet contents would be dumped incorrectly (i.e.,
1609   the output form -x would be wrong on little endian machines because
1610   the protocol dumpers would modify the data).  Thanks to Charles Hannum
1611   (mycroft@gnu.ai.mit.edu) for reporting this problem.
1612
1613 - Added support for decnet protocol dumping thanks to Jeff Mogul
1614   (mogul@pa.dec.com).
1615
1616 - Fix bug that caused length of packet to be incorrectly printed
1617   (off by ether header size) for unknown ethernet types thanks
1618   to Greg Miller (gmiller@kayak.mitre.org).
1619
1620 - Added support for IPX protocol dumping thanks to Brad Parker
1621   (brad@fcr.com).
1622
1623 - Added check to verify IP header checksum under -v thanks to
1624   Brad Parker (brad@fcr.com).
1625
1626 - Move packet capture code to new libpcap library (which is
1627   packaged separately).
1628
1629 - Prototype everything and assume an ansi compiler.
1630
1631 - print-arp.c: Print hardware ethernet addresses if they're not
1632   what we expect.
1633
1634 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1635   Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1636
1637 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1638   (mogul@pa.dec.com).
1639
1640 - print-icmp.c: Byte swap netmask before printing. Thanks to
1641   Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1642
1643 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1644   By default, only the inner packet is dumped, appended with the token
1645   "(encap)".  Under -v, both the inner and output packets are dumped
1646   (on the same line).  Note that the filter applies to the original packet,
1647   not the encapsulated packet.  So if you run tcpdump on a net with an
1648   IP Multicast tunnel, you cannot filter out the datagrams using the
1649   conventional syntax.  (You can filter away all the ip-in-ip traffic
1650   with "not ip proto 4".)
1651
1652 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1653   nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1654
1655 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1656
1657 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1658   (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1659   Add && and || operators
1660
1661 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1662
1663 - Fix bug with -c flag.
1664
1665 v2.2 Fri May 22 17:19:41 PDT 1992
1666
1667 - savefile.c: Remove hack that shouldn't have been exported. Add
1668   truncate checks.
1669
1670 - Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
1671   matches non-echo/reply ICMP packets.
1672
1673 - Many improvements to filter code optimizer.
1674
1675 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1676   so that protocol qualifications are allowed. For example, "ip broadcast"
1677   and "ether multicast" are valid filters.
1678
1679 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1680   Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1681   patches to netinet/if_loop.c.
1682
1683 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1684   Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1685
1686 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1687
1688 v2.1 Tue Jan 28 11:00:14 PST 1992
1689
1690 - Internal release (never publicly exported).
1691
1692 v2.0.1 Sun Jan 26 21:10:10 PDT
1693
1694 - Various byte ordering fixes.
1695
1696 - Add truncation checks.
1697
1698 - inet.c: Support BSD style SIOCGIFCONF.
1699
1700 - nametoaddr.c: Handle multi addresses for single host.
1701
1702 - optimize.c: Rewritten.
1703
1704 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1705   for broadcast nets.
1706
1707 - print-atal.c: Fix an alignment bug (thanks to
1708   stanonik@nprdc.navy.mil) Add missing printf() argument.
1709
1710 - print-bootp.c: First attempt at decoding the vendor buffer.
1711
1712 - print-domain.c: Fix truncation checks.
1713
1714 - print-icmp.c: Calculate length of packets from the ip header.
1715
1716 - print-ip.c: Print frag id in decimal (so it's easier to match up
1717   with non-frags). Add support for ospf, egp and igmp.
1718
1719 - print-nfs.c: Lots of changes.
1720
1721 - print-ntp.c: Make some verbose output depend on -v.
1722
1723 - print-snmp.c: New version from John LoVerso.
1724
1725 - print-tcp.c: Print rfc1072 tcp options.
1726
1727 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1728   (microseconds) worth of precision. Fix uid bugs.
1729
1730 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1731   With this option, you can create an architecture independent binary
1732   trace file in real time, without the overhead of the packet printer.
1733   At a later time, the packets can be filtered (again) and printed.
1734
1735 - BSD is supported.  You must have BPF in your kernel.
1736   Since the filtering is now done in the kernel, fewer packets are
1737   dropped.  In fact, with BPF and the packet dumper option, a measly
1738   Sun 3/50 can keep up with a busy network.
1739
1740 - Compressed SLIP packets can now be dumped, provided you use our
1741   SLIP software and BPF.  These packets are dumped as any other IP
1742   packet; the compressed headers are dumped with the '-e' option.
1743
1744 - Machines with little-endian byte ordering are supported (thanks to
1745   Jeff Mogul).
1746
1747 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1748
1749 - IBM RT and Stanford Enetfilter support has been added by
1750   Rayan Zachariassen <rayan@canet.ca>.  Tcpdump has been tested under
1751   both the vanilla Enetfilter interface, and the extended interface
1752   (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1753
1754 - TFTP packets are now printed (requests only).
1755
1756 - BOOTP packets are now printed.
1757
1758 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1759
1760 - Sparc architectures, including the Sparcstation-1, are now
1761   supported thanks to Steve McCanne and Craig Leres.
1762
1763 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1764   University (micky@cunixc.cc.columbia.edu).
1765
1766 - IP options are now printed.
1767
1768 - RIP packets are now printed.
1769
1770 - There's a -v flag that prints out more information than the
1771   default (e.g., it will enable printing of IP ttl, tos and id)
1772   and -q flag that prints out less (e.g., it will disable
1773   interpretation of AppleTalk-in-UDP).
1774
1775 - The grammar has undergone substantial changes (if you have an
1776   earlier version of tcpdump, you should re-read the manual
1777   entry).
1778
1779   The most useful change is the addition of an expression
1780   syntax that lets you filter on arbitrary fields or values in the
1781   packet.  E.g., "ip[0] > 0x45" would print only packets with IP
1782   options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1783   packets.
1784
1785   The most painful change is that concatenation no longer means
1786   "and" -- e.g., you have to say "host foo and port bar" instead
1787   of "host foo port bar".  The up side to this down is that
1788   repeated qualifiers can be omitted, making most filter
1789   expressions shorter.  E.g., you can now say "ip host foo and
1790   (bar or baz)" to look at ip traffic between hosts foo and bar or
1791   between hosts foo and baz.  [The old way of saying this was "ip
1792   host foo and (ip host bar or ip host baz)".]
1793
1794 v2.0 Sun Jan 13 12:20:40 PST 1991
1795
1796 - Initial public release.
