1380   Bill Fenner (fenner@parc.xerox.com)
1381
1382 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.

1385   Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1386
1387 - Rewrite ospf printer to improve truncation checks.
1388
1389 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1390   (davids@secnet.com). Also, check tcp options to make sure they ar
1391   actually in the tcp header (in addition to the normal truncation
1392   checks). Fix the SACK code to print the N blocks (instead of the
1393   first block N times).
1394
1395 - Don't say really small UDP packets are truncated just because they
1396   aren't big enough to be a RPC. As noted by David Sacerdote.
1397
1398 v3.2.1 Sun Jul 14 03:02:26 PDT 1996

1418   Thanks to John Hawkinson.
1419
1420 - Avoid infinite loop in tcp options printing code. Thanks to Jeffrey
1421   Mogul (mogul@pa.dec.com)
1422
1423 - Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
1424   Thanks to John Hawkinson.
1425
1426 - Added some more packet truncation checks.
1427
1428 - On systems that have it, use sigset() instead of signal() since

1430
1431 - Fixed some more alignment problems on the alpha.
1432

1469
1470 v3.2 Sun Jun 23 02:28:10 PDT 1996
1471
1472 - Print new icmp unreachable codes as suggested by Martin Fredriksson
1473   (martin@msp.se). Also print code value when unknown for icmp redirect
1474   and time exceeded.
1475
1476 - Fix an alignment endian bug in getname(). Thanks to John Hawkinson.
1477
1478 - Define "new" domain record types if not found in arpa/nameserv.h.

1481   types.
1482
1483 - Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
1484
1485 - Added T/TCP options printing. As suggested by Richard Stevens
1486   (rstevens@noao.edu)
1487
1488 - Use autoconf to detect architectures that can't handle misaligned
1489   accesses.
1490
1491 v3.1 Thu Jun 13 20:59:32 PDT 1996
1492
1493 - Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
1494   and bind (as suggested by Charles Hannum).
1495
1496 - Port to GNU autoconf.
1497
1498 - Add support for printing DVMRP and PIM traffic thanks to
1499   Havard Eidnes (Havard.Eidnes@runit.sintef.no).
1500
1501 - Fix AppleTalk, IPX and DECnet byte order problems due to wrong endian
1502   define being referenced. Reported by Terry Kennedy.

1514   (cslater@imatek.com).
1515
1516 - Check return status from malloc/calloc/etc.
1517
1518 - Check return status from pcap_loop() so we can print an error and
1519   exit with a bad status if there were problems.
1520
1521 - Bail if ip option length is <= 0. Resulted from a bug report from
1522   Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).
1523
1524 - Print out a little more information for sun rpc packets.
1525
1526 - Add support for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu).
1527
1528 - Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were
1529   wrong on little endian machines).
1530
1531 - Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
1532   (crawdad@fnal.gov).
1533
1534 - Fix ntp_print() to not print garbage when the stratum is
1535   "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).

1544   octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1545   (toku@dit.co.jp)
1546
1547 - Don't checksum ip header if we don't have all of it. Thanks to John
1548   Hawkinson (jhawk@mit.edu).
1549
1550 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1551   Honig (jhc@bsdi.com)
1552
1553
1554 v3.1a1 Wed May  3 19:21:11 PDT 1995
1555
1556 - Include time.h when SVR4 is defined to avoid problems under Solaris
1557   2.3.
1558
1559 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1560   strings, not the local buffer. Thanks to Stefan Petri
1561   (petri@ibr.cs.tu-bs.de).
1562
1563 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1564   that the selected value was not used. Thanks to Pascal Hennequin
1565   (Pascal.Hennequin@hugo.int-evry.fr).
1566
1567 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1568
1569 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1570
1571 v3.0.3 Sun Oct  1 18:35:00 GMT 1995
1572
1573 - Although there never was a 3.0.3 release, the linux boys cleverly
1574   "released" one in late 1995.
1575
1576 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1577
1578 - Change configuration to not use gcc v2 flags with gcc v1.
1579
1580 - Redo gmt2local() so that it works under BSDI (which seems to return
1581   an empty timezone struct from gettimeofday()). Based on report from
1582   Terry Kennedy (terry@spcvxa.spc.edu).
1583
1584 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1585   on report from Mark Andrews (mandrews@alias.com).
1586
1587 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1588   Orth (ro@techfak.uni-bielefeld.de).
1589
1590 - Fixed printout of connection id for uncompressed tcp slip packets.
1591   Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1592
1593 - Hack around deficiency in Ultrix's make.
1594
1595 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1596
1597 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1598
1599 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1600
1601 v3.0 Mon Jun 20 19:23:27 PDT 1994
1602
1603 - Added support for printing tcp option timestamps thanks to
1604   Mark Andrews (mandrews@alias.com).
1605
1606 - Reorganize protocol dumpers to take const pointers to packets so they
1607   never change the contents (i.e., they used to do endian conversions
1608   in place).  Previously, whenever more than one pass was taken over
1609   the packet, the packet contents would be dumped incorrectly (i.e.,
1610   the output form -x would be wrong on little endian machines because
1611   the protocol dumpers would modify the data).  Thanks to Charles Hannum
1612   (mycroft@gnu.ai.mit.edu) for reporting this problem.
1613
1614 - Added support for decnet protocol dumping thanks to Jeff Mogul
1615   (mogul@pa.dec.com).
1616
1617 - Fix bug that caused length of packet to be incorrectly printed
1618   (off by ether header size) for unknown ethernet types thanks
1619   to Greg Miller (gmiller@kayak.mitre.org).
1620
1621 - Added support for IPX protocol dumping thanks to Brad Parker
1622   (brad@fcr.com).
1623
1624 - Added check to verify IP header checksum under -v thanks to
1625   Brad Parker (brad@fcr.com).
1626
1627 - Move packet capture code to new libpcap library (which is
1628   packaged separately).
1629
1630 - Prototype everything and assume an ansi compiler.
1631
1632 - print-arp.c: Print hardware ethernet addresses if they're not
1633   what we expect.
1634
1635 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1636   Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1637
1638 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1639   (mogul@pa.dec.com).
1640
1641 - print-icmp.c: Byte swap netmask before printing. Thanks to
1642   Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1643
1644 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1645   By default, only the inner packet is dumped, appended with the token
1646   "(encap)".  Under -v, both the inner and output packets are dumped
1647   (on the same line).  Note that the filter applies to the original packet,
1648   not the encapsulated packet.  So if you run tcpdump on a net with an
1649   IP Multicast tunnel, you cannot filter out the datagrams using the
1650   conventional syntax.  (You can filter away all the ip-in-ip traffic
1651   with "not ip proto 4".)
1652
1653 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1654   nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1655
1656 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1657
1658 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1659   (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1660   Add && and || operators
1661
1662 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1663
1664 - Fix bug with -c flag.
1665
1666 v2.2 Fri May 22 17:19:41 PDT 1992
1667
1668 - savefile.c: Remove hack that shouldn't have been exported. Add
1669   truncate checks.
1670
1671 - Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
1672   matches non-echo/reply ICMP packets.
1673
1674 - Many improvements to filter code optimizer.
1675
1676 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1677   so that protocol qualifications are allowed. For example, "ip broadcast"
1678   and "ether multicast" are valid filters.
1679
1680 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1681   Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1682   patches to netinet/if_loop.c.
1683
1684 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1685   Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1686
1687 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1688
1689 v2.1 Tue Jan 28 11:00:14 PST 1992
1690
1691 - Internal release (never publicly exported).
1692
1693 v2.0.1 Sun Jan 26 21:10:10 PDT
1694
1695 - Various byte ordering fixes.
1696
1697 - Add truncation checks.
1698
1699 - inet.c: Support BSD style SIOCGIFCONF.
1700
1701 - nametoaddr.c: Handle multi addresses for single host.
1702
1703 - optimize.c: Rewritten.
1704
1705 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1706   for broadcast nets.
1707
1708 - print-atal.c: Fix an alignment bug (thanks to
1709   stanonik@nprdc.navy.mil) Add missing printf() argument.
1710
1711 - print-bootp.c: First attempt at decoding the vendor buffer.
1712
1713 - print-domain.c: Fix truncation checks.
1714
1715 - print-icmp.c: Calculate length of packets from the ip header.
1716
1717 - print-ip.c: Print frag id in decimal (so it's easier to match up
1718   with non-frags). Add support for ospf, egp and igmp.
1719
1720 - print-nfs.c: Lots of changes.
1721
1722 - print-ntp.c: Make some verbose output depend on -v.
1723
1724 - print-snmp.c: New version from John LoVerso.
1725
1726 - print-tcp.c: Print rfc1072 tcp options.
1727
1728 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1729   (microseconds) worth of precision. Fix uid bugs.
1730
1731 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1732   With this option, you can create an architecture independent binary
1733   trace file in real time, without the overhead of the packet printer.
1734   At a later time, the packets can be filtered (again) and printed.
1735
1736 - BSD is supported.  You must have BPF in your kernel.
1737   Since the filtering is now done in the kernel, fewer packets are
1738   dropped.  In fact, with BPF and the packet dumper option, a measly
1739   Sun 3/50 can keep up with a busy network.
1740
1741 - Compressed SLIP packets can now be dumped, provided you use our
1742   SLIP software and BPF.  These packets are dumped as any other IP
1743   packet; the compressed headers are dumped with the '-e' option.
1744
1745 - Machines with little-endian byte ordering are supported (thanks to
1746   Jeff Mogul).
1747
1748 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1749
1750 - IBM RT and Stanford Enetfilter support has been added by
1751   Rayan Zachariassen <rayan@canet.ca>.  Tcpdump has been tested under
1752   both the vanilla Enetfilter interface, and the extended interface
1753   (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1754
1755 - TFTP packets are now printed (requests only).
1756
1757 - BOOTP packets are now printed.
1758
1759 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1760
1761 - Sparc architectures, including the Sparcstation-1, are now
1762   supported thanks to Steve McCanne and Craig Leres.
1763
1764 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1765   University (micky@cunixc.cc.columbia.edu).
1766
1767 - IP options are now printed.
1768
1769 - RIP packets are now printed.
1770
1771 - There's a -v flag that prints out more information than the
1772   default (e.g., it will enable printing of IP ttl, tos and id)
1773   and -q flag that prints out less (e.g., it will disable
1774   interpretation of AppleTalk-in-UDP).
1775
1776 - The grammar has undergone substantial changes (if you have an
1777   earlier version of tcpdump, you should re-read the manual
1778   entry).
1779
1780   The most useful change is the addition of an expression
1781   syntax that lets you filter on arbitrary fields or values in the
1782   packet.  E.g., "ip[0] > 0x45" would print only packets with IP
1783   options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1784   packets.
1785
1786   The most painful change is that concatenation no longer means
1787   "and" -- e.g., you have to say "host foo and port bar" instead
1788   of "host foo port bar".  The up side to this down is that
1789   repeated qualifiers can be omitted, making most filter
1790   expressions shorter.  E.g., you can now say "ip host foo and
1791   (bar or baz)" to look at ip traffic between hosts foo and bar or
1792   between hosts foo and baz.  [The old way of saying this was "ip
1793   host foo and (ip host bar or ip host baz)".]
1794
1795 v2.0 Sun Jan 13 12:20:40 PST 1991
1796
1797 - Initial public release.
