1383   Bill Fenner (fenner@parc.xerox.com)
1384
1385 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.

1387 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
1388   Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1389
1390 - Rewrite ospf printer to improve truncation checks.
1391
1392 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1393   (davids@secnet.com). Also, check tcp options to make sure they ar
1394   actually in the tcp header (in addition to the normal truncation
1395   checks). Fix the SACK code to print the N blocks (instead of the
1396   first block N times).
1397
1398 - Don't say really small UDP packets are truncated just because they
1399   aren't big enough to be a RPC. As noted by David Sacerdote.
1400

1422
1423 - Avoid infinite loop in tcp options printing code. Thanks to Jeffrey
1424   Mogul (mogul@pa.dec.com)
1425
1426 - Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
1427   Thanks to John Hawkinson.
1428
1429 - Added some more packet truncation checks.
1430
1431 - On systems that have it, use sigset() instead of signal() since

1433
1434 - Fixed some more alignment problems on the alpha.
1435

1472
1473 v3.2 Sun Jun 23 02:28:10 PDT 1996
1474
1475 - Print new icmp unreachable codes as suggested by Martin Fredriksson
1476   (martin@msp.se). Also print code value when unknown for icmp redirect
1477   and time exceeded.
1478
1479 - Fix an alignment endian bug in getname(). Thanks to John Hawkinson.
1480
1481 - Define "new" domain record types if not found in arpa/nameserv.h.

1484   types.
1485
1486 - Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
1487
1488 - Added T/TCP options printing. As suggested by Richard Stevens
1489   (rstevens@noao.edu)
1490
1491 - Use autoconf to detect architectures that can't handle misaligned
1492   accesses.
1493
1494 v3.1 Thu Jun 13 20:59:32 PDT 1996
1495
1496 - Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
1497   and bind (as suggested by Charles Hannum).

1499 - Port to GNU autoconf.
1500
1501 - Add support for printing DVMRP and PIM traffic thanks to
1502   Havard Eidnes (Havard.Eidnes@runit.sintef.no).
1503
1504 - Fix AppleTalk, IPX and DECnet byte order problems due to wrong endian
1505   define being referenced. Reported by Terry Kennedy.

1517   (cslater@imatek.com).
1518
1519 - Check return status from malloc/calloc/etc.
1520
1521 - Check return status from pcap_loop() so we can print an error and
1522   exit with a bad status if there were problems.
1523
1524 - Bail if ip option length is <= 0. Resulted from a bug report from
1525   Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).
1526
1527 - Print out a little more information for sun rpc packets.
1528
1529 - Add support for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu).
1530
1531 - Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were
1532   wrong on little endian machines).
1533
1534 - Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
1535   (crawdad@fnal.gov).
1536
1537 - Fix ntp_print() to not print garbage when the stratum is
1538   "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).

1551   Hawkinson (jhawk@mit.edu).
1552
1553 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1554   Honig (jhc@bsdi.com)
1555
1556
1557 v3.1a1 Wed May  3 19:21:11 PDT 1995
1558
1559 - Include time.h when SVR4 is defined to avoid problems under Solaris
1560   2.3.
1561
1562 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1563   strings, not the local buffer. Thanks to Stefan Petri
1564   (petri@ibr.cs.tu-bs.de).
1565
1566 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1567   that the selected value was not used. Thanks to Pascal Hennequin
1568   (Pascal.Hennequin@hugo.int-evry.fr).
1569
1570 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1571
1572 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1573
1574 v3.0.3 Sun Oct  1 18:35:00 GMT 1995
1575
1576 - Although there never was a 3.0.3 release, the linux boys cleverly
1577   "released" one in late 1995.
1578
1579 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1580
1581 - Change configuration to not use gcc v2 flags with gcc v1.
1582
1583 - Redo gmt2local() so that it works under BSDI (which seems to return
1584   an empty timezone struct from gettimeofday()). Based on report from
1585   Terry Kennedy (terry@spcvxa.spc.edu).
1586
1587 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1588   on report from Mark Andrews (mandrews@alias.com).
1589
1590 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1591   Orth (ro@techfak.uni-bielefeld.de).
1592
1593 - Fixed printout of connection id for uncompressed tcp slip packets.
1594   Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1595
1596 - Hack around deficiency in Ultrix's make.
1597
1598 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1599
1600 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1601
1602 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1603
1604 v3.0 Mon Jun 20 19:23:27 PDT 1994
1605
1606 - Added support for printing tcp option timestamps thanks to
1607   Mark Andrews (mandrews@alias.com).
1608
1609 - Reorganize protocol dumpers to take const pointers to packets so they
1610   never change the contents (i.e., they used to do endian conversions
1611   in place).  Previously, whenever more than one pass was taken over
1612   the packet, the packet contents would be dumped incorrectly (i.e.,
1613   the output form -x would be wrong on little endian machines because
1614   the protocol dumpers would modify the data).  Thanks to Charles Hannum
1615   (mycroft@gnu.ai.mit.edu) for reporting this problem.
1616
1617 - Added support for decnet protocol dumping thanks to Jeff Mogul
1618   (mogul@pa.dec.com).
1619
1620 - Fix bug that caused length of packet to be incorrectly printed
1621   (off by ether header size) for unknown ethernet types thanks
1622   to Greg Miller (gmiller@kayak.mitre.org).
1623
1624 - Added support for IPX protocol dumping thanks to Brad Parker
1625   (brad@fcr.com).
1626
1627 - Added check to verify IP header checksum under -v thanks to
1628   Brad Parker (brad@fcr.com).
1629
1630 - Move packet capture code to new libpcap library (which is
1631   packaged separately).
1632
1633 - Prototype everything and assume an ansi compiler.
1634
1635 - print-arp.c: Print hardware ethernet addresses if they're not
1636   what we expect.
1637
1638 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1639   Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1640
1641 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1642   (mogul@pa.dec.com).
1643
1644 - print-icmp.c: Byte swap netmask before printing. Thanks to
1645   Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1646
1647 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1648   By default, only the inner packet is dumped, appended with the token
1649   "(encap)".  Under -v, both the inner and output packets are dumped
1650   (on the same line).  Note that the filter applies to the original packet,
1651   not the encapsulated packet.  So if you run tcpdump on a net with an
1652   IP Multicast tunnel, you cannot filter out the datagrams using the
1653   conventional syntax.  (You can filter away all the ip-in-ip traffic
1654   with "not ip proto 4".)
1655
1656 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1657   nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1658
1659 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1660
1661 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1662   (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1663   Add && and || operators
1664
1665 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1666
1667 - Fix bug with -c flag.
1668
1669 v2.2 Fri May 22 17:19:41 PDT 1992
1670
1671 - savefile.c: Remove hack that shouldn't have been exported. Add
1672   truncate checks.
1673
1674 - Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
1675   matches non-echo/reply ICMP packets.
1676
1677 - Many improvements to filter code optimizer.
1678
1679 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1680   so that protocol qualifications are allowed. For example, "ip broadcast"
1681   and "ether multicast" are valid filters.
1682
1683 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1684   Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1685   patches to netinet/if_loop.c.
1686
1687 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1688   Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1689
1690 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1691
1692 v2.1 Tue Jan 28 11:00:14 PST 1992
1693
1694 - Internal release (never publicly exported).
1695
1696 v2.0.1 Sun Jan 26 21:10:10 PDT
1697
1698 - Various byte ordering fixes.
1699
1700 - Add truncation checks.
1701
1702 - inet.c: Support BSD style SIOCGIFCONF.
1703
1704 - nametoaddr.c: Handle multi addresses for single host.
1705
1706 - optimize.c: Rewritten.
1707
1708 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1709   for broadcast nets.
1710
1711 - print-atal.c: Fix an alignment bug (thanks to
1712   stanonik@nprdc.navy.mil) Add missing printf() argument.
1713
1714 - print-bootp.c: First attempt at decoding the vendor buffer.
1715
1716 - print-domain.c: Fix truncation checks.
1717
1718 - print-icmp.c: Calculate length of packets from the ip header.
1719
1720 - print-ip.c: Print frag id in decimal (so it's easier to match up
1721   with non-frags). Add support for ospf, egp and igmp.
1722
1723 - print-nfs.c: Lots of changes.
1724
1725 - print-ntp.c: Make some verbose output depend on -v.
1726
1727 - print-snmp.c: New version from John LoVerso.
1728
1729 - print-tcp.c: Print rfc1072 tcp options.
1730
1731 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1732   (microseconds) worth of precision. Fix uid bugs.
1733
1734 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1735   With this option, you can create an architecture independent binary
1736   trace file in real time, without the overhead of the packet printer.
1737   At a later time, the packets can be filtered (again) and printed.
1738
1739 - BSD is supported.  You must have BPF in your kernel.
1740   Since the filtering is now done in the kernel, fewer packets are
1741   dropped.  In fact, with BPF and the packet dumper option, a measly
1742   Sun 3/50 can keep up with a busy network.
1743
1744 - Compressed SLIP packets can now be dumped, provided you use our
1745   SLIP software and BPF.  These packets are dumped as any other IP
1746   packet; the compressed headers are dumped with the '-e' option.
1747
1748 - Machines with little-endian byte ordering are supported (thanks to
1749   Jeff Mogul).
1750
1751 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1752
1753 - IBM RT and Stanford Enetfilter support has been added by
1754   Rayan Zachariassen <rayan@canet.ca>.  Tcpdump has been tested under
1755   both the vanilla Enetfilter interface, and the extended interface
1756   (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1757
1758 - TFTP packets are now printed (requests only).
1759
1760 - BOOTP packets are now printed.
1761
1762 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1763
1764 - Sparc architectures, including the Sparcstation-1, are now
1765   supported thanks to Steve McCanne and Craig Leres.
1766
1767 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1768   University (micky@cunixc.cc.columbia.edu).
1769
1770 - IP options are now printed.
1771
1772 - RIP packets are now printed.
1773
1774 - There's a -v flag that prints out more information than the
1775   default (e.g., it will enable printing of IP ttl, tos and id)
1776   and -q flag that prints out less (e.g., it will disable
1777   interpretation of AppleTalk-in-UDP).
1778
1779 - The grammar has undergone substantial changes (if you have an
1780   earlier version of tcpdump, you should re-read the manual
1781   entry).
1782
1783   The most useful change is the addition of an expression
1784   syntax that lets you filter on arbitrary fields or values in the
1785   packet.  E.g., "ip[0] > 0x45" would print only packets with IP
1786   options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1787   packets.
1788
1789   The most painful change is that concatenation no longer means
1790   "and" -- e.g., you have to say "host foo and port bar" instead
1791   of "host foo port bar".  The up side to this down is that
1792   repeated qualifiers can be omitted, making most filter
1793   expressions shorter.  E.g., you can now say "ip host foo and
1794   (bar or baz)" to look at ip traffic between hosts foo and bar or
1795   between hosts foo and baz.  [The old way of saying this was "ip
1796   host foo and (ip host bar or ip host baz)".]
1797
1798 v2.0 Sun Jan 13 12:20:40 PST 1991
1799
1800 - Initial public release.
