1378   Bill Fenner (fenner@parc.xerox.com)
1379
1380 - Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.

1382 - Fix dvmrp printer truncation checks and add a dvmrp probe printer.
1383   Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1384
1385 - Rewrite ospf printer to improve truncation checks.
1386
1387 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1388   (davids@secnet.com). Also, check tcp options to make sure they ar
1389   actually in the tcp header (in addition to the normal truncation
1390   checks). Fix the SACK code to print the N blocks (instead of the
1391   first block N times).
1392
1393 - Don't say really small UDP packets are truncated just because they
1394   aren't big enough to be a RPC. As noted by David Sacerdote.
1395

1416   Thanks to John Hawkinson.
1417
1418 - Avoid infinite loop in tcp options printing code. Thanks to Jeffrey
1419   Mogul (mogul@pa.dec.com)
1420
1421 - Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
1422   Thanks to John Hawkinson.
1423
1424 - Added some more packet truncation checks.
1425
1426 - On systems that have it, use sigset() instead of signal() since
1427   signal() has different semantics on these systems.
1428
1429 - Fixed some more alignment problems on the alpha.
1430
1431 - Add code to massage unprintable characters in the domain and ipx

1467
1468 v3.2 Sun Jun 23 02:28:10 PDT 1996
1469
1470 - Print new icmp unreachable codes as suggested by Martin Fredriksson
1471   (martin@msp.se). Also print code value when unknown for icmp redirect
1472   and time exceeded.
1473
1474 - Fix an alignment endian bug in getname(). Thanks to John Hawkinson.
1475
1476 - Define "new" domain record types if not found in arpa/nameserv.h.

1479   types.
1480
1481 - Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
1482
1483 - Added T/TCP options printing. As suggested by Richard Stevens
1484   (rstevens@noao.edu)
1485
1486 - Use autoconf to detect architectures that can't handle misaligned
1487   accesses.
1488
1489 v3.1 Thu Jun 13 20:59:32 PDT 1996
1490
1491 - Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
1492   and bind (as suggested by Charles Hannum).
1493
1494 - Port to GNU autoconf.
1495
1496 - Add support for printing DVMRP and PIM traffic thanks to
1497   Havard Eidnes (Havard.Eidnes@runit.sintef.no).
1498
1499 - Fix AppleTalk, IPX and DECnet byte order problems due to wrong endian
1500   define being referenced. Reported by Terry Kennedy.

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

1542   octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1543   (toku@dit.co.jp)
1544
1545 - Don't checksum ip header if we don't have all of it. Thanks to John
1546   Hawkinson (jhawk@mit.edu).
1547
1548 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1549   Honig (jhc@bsdi.com)
1550
1551
1552 v3.1a1 Wed May  3 19:21:11 PDT 1995
1553
1554 - Include time.h when SVR4 is defined to avoid problems under Solaris
1555   2.3.
1556
1557 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1558   strings, not the local buffer. Thanks to Stefan Petri
1559   (petri@ibr.cs.tu-bs.de).
1560
1561 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1562   that the selected value was not used. Thanks to Pascal Hennequin
1563   (Pascal.Hennequin@hugo.int-evry.fr).
1564
1565 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1566
1567 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1568
1569 v3.0.3 Sun Oct  1 18:35:00 GMT 1995
1570
1571 - Although there never was a 3.0.3 release, the linux boys cleverly
1572   "released" one in late 1995.
1573
1574 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1575
1576 - Change configuration to not use gcc v2 flags with gcc v1.
1577
1578 - Redo gmt2local() so that it works under BSDI (which seems to return
1579   an empty timezone struct from gettimeofday()). Based on report from
1580   Terry Kennedy (terry@spcvxa.spc.edu).
1581
1582 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1583   on report from Mark Andrews (mandrews@alias.com).
1584
1585 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1586   Orth (ro@techfak.uni-bielefeld.de).
1587
1588 - Fixed printout of connection id for uncompressed tcp slip packets.
1589   Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1590
1591 - Hack around deficiency in Ultrix's make.
1592
1593 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1594
1595 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1596
1597 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1598
1599 v3.0 Mon Jun 20 19:23:27 PDT 1994
1600
1601 - Added support for printing tcp option timestamps thanks to
1602   Mark Andrews (mandrews@alias.com).
1603
1604 - Reorganize protocol dumpers to take const pointers to packets so they
1605   never change the contents (i.e., they used to do endian conversions
1606   in place).  Previously, whenever more than one pass was taken over
1607   the packet, the packet contents would be dumped incorrectly (i.e.,
1608   the output form -x would be wrong on little endian machines because
1609   the protocol dumpers would modify the data).  Thanks to Charles Hannum
1610   (mycroft@gnu.ai.mit.edu) for reporting this problem.
1611
1612 - Added support for decnet protocol dumping thanks to Jeff Mogul
1613   (mogul@pa.dec.com).
1614
1615 - Fix bug that caused length of packet to be incorrectly printed
1616   (off by ether header size) for unknown ethernet types thanks
1617   to Greg Miller (gmiller@kayak.mitre.org).
1618
1619 - Added support for IPX protocol dumping thanks to Brad Parker
1620   (brad@fcr.com).
1621
1622 - Added check to verify IP header checksum under -v thanks to
1623   Brad Parker (brad@fcr.com).
1624
1625 - Move packet capture code to new libpcap library (which is
1626   packaged separately).
1627
1628 - Prototype everything and assume an ansi compiler.
1629
1630 - print-arp.c: Print hardware ethernet addresses if they're not
1631   what we expect.
1632
1633 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1634   Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1635
1636 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1637   (mogul@pa.dec.com).
1638
1639 - print-icmp.c: Byte swap netmask before printing. Thanks to
1640   Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1641
1642 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1643   By default, only the inner packet is dumped, appended with the token
1644   "(encap)".  Under -v, both the inner and output packets are dumped
1645   (on the same line).  Note that the filter applies to the original packet,
1646   not the encapsulated packet.  So if you run tcpdump on a net with an
1647   IP Multicast tunnel, you cannot filter out the datagrams using the
1648   conventional syntax.  (You can filter away all the ip-in-ip traffic
1649   with "not ip proto 4".)
1650
1651 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1652   nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1653
1654 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1655
1656 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1657   (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1658   Add && and || operators
1659
1660 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1661
1662 - Fix bug with -c flag.
1663
1664 v2.2 Fri May 22 17:19:41 PDT 1992
1665
1666 - savefile.c: Remove hack that shouldn't have been exported. Add
1667   truncate checks.
1668
1669 - Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
1670   matches non-echo/reply ICMP packets.
1671
1672 - Many improvements to filter code optimizer.
1673
1674 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1675   so that protocol qualifications are allowed. For example, "ip broadcast"
1676   and "ether multicast" are valid filters.
1677
1678 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1679   Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1680   patches to netinet/if_loop.c.
1681
1682 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1683   Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1684
1685 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1686
1687 v2.1 Tue Jan 28 11:00:14 PST 1992
1688
1689 - Internal release (never publicly exported).
1690
1691 v2.0.1 Sun Jan 26 21:10:10 PDT
1692
1693 - Various byte ordering fixes.
1694
1695 - Add truncation checks.
1696
1697 - inet.c: Support BSD style SIOCGIFCONF.
1698
1699 - nametoaddr.c: Handle multi addresses for single host.
1700
1701 - optimize.c: Rewritten.
1702
1703 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1704   for broadcast nets.
1705
1706 - print-atal.c: Fix an alignment bug (thanks to
1707   stanonik@nprdc.navy.mil) Add missing printf() argument.
1708
1709 - print-bootp.c: First attempt at decoding the vendor buffer.
1710
1711 - print-domain.c: Fix truncation checks.
1712
1713 - print-icmp.c: Calculate length of packets from the ip header.
1714
1715 - print-ip.c: Print frag id in decimal (so it's easier to match up
1716   with non-frags). Add support for ospf, egp and igmp.
1717
1718 - print-nfs.c: Lots of changes.
1719
1720 - print-ntp.c: Make some verbose output depend on -v.
1721
1722 - print-snmp.c: New version from John LoVerso.
1723
1724 - print-tcp.c: Print rfc1072 tcp options.
1725
1726 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1727   (microseconds) worth of precision. Fix uid bugs.
1728
1729 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1730   With this option, you can create an architecture independent binary
1731   trace file in real time, without the overhead of the packet printer.
1732   At a later time, the packets can be filtered (again) and printed.
1733
1734 - BSD is supported.  You must have BPF in your kernel.
1735   Since the filtering is now done in the kernel, fewer packets are
1736   dropped.  In fact, with BPF and the packet dumper option, a measly
1737   Sun 3/50 can keep up with a busy network.
1738
1739 - Compressed SLIP packets can now be dumped, provided you use our
1740   SLIP software and BPF.  These packets are dumped as any other IP
1741   packet; the compressed headers are dumped with the '-e' option.
1742
1743 - Machines with little-endian byte ordering are supported (thanks to
1744   Jeff Mogul).
1745
1746 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1747
1748 - IBM RT and Stanford Enetfilter support has been added by
1749   Rayan Zachariassen <rayan@canet.ca>.  Tcpdump has been tested under
1750   both the vanilla Enetfilter interface, and the extended interface
1751   (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1752
1753 - TFTP packets are now printed (requests only).
1754
1755 - BOOTP packets are now printed.
1756
1757 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1758
1759 - Sparc architectures, including the Sparcstation-1, are now
1760   supported thanks to Steve McCanne and Craig Leres.
1761
1762 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1763   University (micky@cunixc.cc.columbia.edu).
1764
1765 - IP options are now printed.
1766
1767 - RIP packets are now printed.
1768
1769 - There's a -v flag that prints out more information than the
1770   default (e.g., it will enable printing of IP ttl, tos and id)
1771   and -q flag that prints out less (e.g., it will disable
1772   interpretation of AppleTalk-in-UDP).
1773
1774 - The grammar has undergone substantial changes (if you have an
1775   earlier version of tcpdump, you should re-read the manual
1776   entry).
1777
1778   The most useful change is the addition of an expression
1779   syntax that lets you filter on arbitrary fields or values in the
1780   packet.  E.g., "ip[0] > 0x45" would print only packets with IP
1781   options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1782   packets.
1783
1784   The most painful change is that concatenation no longer means
1785   "and" -- e.g., you have to say "host foo and port bar" instead
1786   of "host foo port bar".  The up side to this down is that
1787   repeated qualifiers can be omitted, making most filter
1788   expressions shorter.  E.g., you can now say "ip host foo and
1789   (bar or baz)" to look at ip traffic between hosts foo and bar or
1790   between hosts foo and baz.  [The old way of saying this was "ip
1791   host foo and (ip host bar or ip host baz)".]
1792
1793 v2.0 Sun Jan 13 12:20:40 PST 1991
1794
1795 - Initial public release.
