1344   Sacerdote (davids@silence.secnet.com)
1345
1346 - Detect group wheel and use it as the default since BSD/OS' install
1347   can't hack numeric groups. Reported by David Sacerdote.
1348
1349 - AIX needs special loader options. Thanks to Jonathan I. Kamens
1350   (jik@cam.ov.com)

1396
1397 - Don't parse tcp options past the EOL. As noted by David Sacerdote
1398   (davids@secnet.com). Also, check tcp options to make sure they ar
1399   actually in the tcp header (in addition to the normal truncation
1400   checks). Fix the SACK code to print the N blocks (instead of the
1401   first block N times).
1402
1403 - Don't say really small UDP packets are truncated just because they
1404   aren't big enough to be a RPC. As noted by David Sacerdote.
1405

1426   Thanks to John Hawkinson.
1427
1428 - Avoid infinite loop in tcp options printing code. Thanks to Jeffrey
1429   Mogul (mogul@pa.dec.com)
1430
1431 - Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
1432   Thanks to John Hawkinson.
1433
1434 - Added some more packet truncation checks.
1435
1436 - On systems that have it, use sigset() instead of signal() since
1437   signal() has different semantics on these systems.
1438
1439 - Fixed some more alignment problems on the alpha.
1440
1441 - Add code to massage unprintable characters in the domain and ipx

1477
1478 v3.2 Sun Jun 23 02:28:10 PDT 1996
1479
1480 - Print new icmp unreachable codes as suggested by Martin Fredriksson
1481   (martin@msp.se). Also print code value when unknown for icmp redirect
1482   and time exceeded.
1483
1484 - Fix an alignment endian bug in getname(). Thanks to John Hawkinson.
1485
1486 - Define "new" domain record types if not found in arpa/nameserv.h.

1489   types.
1490
1491 - Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
1492
1493 - Added T/TCP options printing. As suggested by Richard Stevens
1494   (rstevens@noao.edu)
1495
1496 - Use autoconf to detect architectures that can't handle misaligned
1497   accesses.
1498
1499 v3.1 Thu Jun 13 20:59:32 PDT 1996
1500
1501 - Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
1502   and bind (as suggested by Charles Hannum).

1504 - Port to GNU autoconf.
1505
1506 - Add support for printing DVMRP and PIM traffic thanks to
1507   Havard Eidnes (Havard.Eidnes@runit.sintef.no).
1508
1509 - Fix AppleTalk, IPX and DECnet byte order problems due to wrong endian
1510   define being referenced. Reported by Terry Kennedy.

1522   (cslater@imatek.com).
1523
1524 - Check return status from malloc/calloc/etc.
1525
1526 - Check return status from pcap_loop() so we can print an error and
1527   exit with a bad status if there were problems.
1528
1529 - Bail if ip option length is <= 0. Resulted from a bug report from
1530   Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).
1531
1532 - Print out a little more information for sun rpc packets.
1533
1534 - Add support for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu).
1535
1536 - Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were
1537   wrong on little endian machines).
1538
1539 - Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
1540   (crawdad@fnal.gov).
1541
1542 - Fix ntp_print() to not print garbage when the stratum is
1543   "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).

1552   octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1553   (toku@dit.co.jp)
1554
1555 - Don't checksum ip header if we don't have all of it. Thanks to John
1556   Hawkinson (jhawk@mit.edu).
1557
1558 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1559   Honig (jhc@bsdi.com)
1560
1561
1562 v3.1a1 Wed May  3 19:21:11 PDT 1995
1563
1564 - Include time.h when SVR4 is defined to avoid problems under Solaris
1565   2.3.
1566
1567 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1568   strings, not the local buffer. Thanks to Stefan Petri
1569   (petri@ibr.cs.tu-bs.de).
1570
1571 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1572   that the selected value was not used. Thanks to Pascal Hennequin
1573   (Pascal.Hennequin@hugo.int-evry.fr).
1574
1575 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1576
1577 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1578
1579 v3.0.3 Sun Oct  1 18:35:00 GMT 1995
1580
1581 - Although there never was a 3.0.3 release, the linux boys cleverly
1582   "released" one in late 1995.
1583
1584 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1585
1586 - Change configuration to not use gcc v2 flags with gcc v1.
1587
1588 - Redo gmt2local() so that it works under BSDI (which seems to return
1589   an empty timezone struct from gettimeofday()). Based on report from
1590   Terry Kennedy (terry@spcvxa.spc.edu).
1591
1592 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1593   on report from Mark Andrews (mandrews@alias.com).
1594
1595 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1596   Orth (ro@techfak.uni-bielefeld.de).
1597
1598 - Fixed printout of connection id for uncompressed tcp slip packets.
1599   Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1600
1601 - Hack around deficiency in Ultrix's make.
1602
1603 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1604
1605 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1606
1607 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1608
1609 v3.0 Mon Jun 20 19:23:27 PDT 1994
1610
1611 - Added support for printing tcp option timestamps thanks to
1612   Mark Andrews (mandrews@alias.com).
1613
1614 - Reorganize protocol dumpers to take const pointers to packets so they
1615   never change the contents (i.e., they used to do endian conversions
1616   in place).  Previously, whenever more than one pass was taken over
1617   the packet, the packet contents would be dumped incorrectly (i.e.,
1618   the output form -x would be wrong on little endian machines because
1619   the protocol dumpers would modify the data).  Thanks to Charles Hannum
1620   (mycroft@gnu.ai.mit.edu) for reporting this problem.
1621
1622 - Added support for decnet protocol dumping thanks to Jeff Mogul
1623   (mogul@pa.dec.com).
1624
1625 - Fix bug that caused length of packet to be incorrectly printed
1626   (off by ether header size) for unknown ethernet types thanks
1627   to Greg Miller (gmiller@kayak.mitre.org).
1628
1629 - Added support for IPX protocol dumping thanks to Brad Parker
1630   (brad@fcr.com).
1631
1632 - Added check to verify IP header checksum under -v thanks to
1633   Brad Parker (brad@fcr.com).
1634
1635 - Move packet capture code to new libpcap library (which is
1636   packaged separately).
1637
1638 - Prototype everything and assume an ansi compiler.
1639
1640 - print-arp.c: Print hardware ethernet addresses if they're not
1641   what we expect.
1642
1643 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1644   Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1645
1646 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1647   (mogul@pa.dec.com).
1648
1649 - print-icmp.c: Byte swap netmask before printing. Thanks to
1650   Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1651
1652 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1653   By default, only the inner packet is dumped, appended with the token
1654   "(encap)".  Under -v, both the inner and output packets are dumped
1655   (on the same line).  Note that the filter applies to the original packet,
1656   not the encapsulated packet.  So if you run tcpdump on a net with an
1657   IP Multicast tunnel, you cannot filter out the datagrams using the
1658   conventional syntax.  (You can filter away all the ip-in-ip traffic
1659   with "not ip proto 4".)
1660
1661 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1662   nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1663
1664 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1665
1666 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1667   (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1668   Add && and || operators
1669
1670 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1671
1672 - Fix bug with -c flag.
1673
1674 v2.2 Fri May 22 17:19:41 PDT 1992
1675
1676 - savefile.c: Remove hack that shouldn't have been exported. Add
1677   truncate checks.
1678
1679 - Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
1680   matches non-echo/reply ICMP packets.
1681
1682 - Many improvements to filter code optimizer.
1683
1684 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1685   so that protocol qualifications are allowed. For example, "ip broadcast"
1686   and "ether multicast" are valid filters.
1687
1688 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1689   Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1690   patches to netinet/if_loop.c.
1691
1692 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1693   Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1694
1695 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1696
1697 v2.1 Tue Jan 28 11:00:14 PST 1992
1698
1699 - Internal release (never publicly exported).
1700
1701 v2.0.1 Sun Jan 26 21:10:10 PDT
1702
1703 - Various byte ordering fixes.
1704
1705 - Add truncation checks.
1706
1707 - inet.c: Support BSD style SIOCGIFCONF.
1708
1709 - nametoaddr.c: Handle multi addresses for single host.
1710
1711 - optimize.c: Rewritten.
1712
1713 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1714   for broadcast nets.
1715
1716 - print-atal.c: Fix an alignment bug (thanks to
1717   stanonik@nprdc.navy.mil) Add missing printf() argument.
1718
1719 - print-bootp.c: First attempt at decoding the vendor buffer.
1720
1721 - print-domain.c: Fix truncation checks.
1722
1723 - print-icmp.c: Calculate length of packets from the ip header.
1724
1725 - print-ip.c: Print frag id in decimal (so it's easier to match up
1726   with non-frags). Add support for ospf, egp and igmp.
1727
1728 - print-nfs.c: Lots of changes.
1729
1730 - print-ntp.c: Make some verbose output depend on -v.
1731
1732 - print-snmp.c: New version from John LoVerso.
1733
1734 - print-tcp.c: Print rfc1072 tcp options.
1735
1736 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1737   (microseconds) worth of precision. Fix uid bugs.
1738
1739 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1740   With this option, you can create an architecture independent binary
1741   trace file in real time, without the overhead of the packet printer.
1742   At a later time, the packets can be filtered (again) and printed.
1743
1744 - BSD is supported.  You must have BPF in your kernel.
1745   Since the filtering is now done in the kernel, fewer packets are
1746   dropped.  In fact, with BPF and the packet dumper option, a measly
1747   Sun 3/50 can keep up with a busy network.
1748
1749 - Compressed SLIP packets can now be dumped, provided you use our
1750   SLIP software and BPF.  These packets are dumped as any other IP
1751   packet; the compressed headers are dumped with the '-e' option.
1752
1753 - Machines with little-endian byte ordering are supported (thanks to
1754   Jeff Mogul).
1755
1756 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1757
1758 - IBM RT and Stanford Enetfilter support has been added by
1759   Rayan Zachariassen <rayan@canet.ca>.  Tcpdump has been tested under
1760   both the vanilla Enetfilter interface, and the extended interface
1761   (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1762
1763 - TFTP packets are now printed (requests only).
1764
1765 - BOOTP packets are now printed.
1766
1767 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1768
1769 - Sparc architectures, including the Sparcstation-1, are now
1770   supported thanks to Steve McCanne and Craig Leres.
1771
1772 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1773   University (micky@cunixc.cc.columbia.edu).
1774
1775 - IP options are now printed.
1776
1777 - RIP packets are now printed.
1778
1779 - There's a -v flag that prints out more information than the
1780   default (e.g., it will enable printing of IP ttl, tos and id)
1781   and -q flag that prints out less (e.g., it will disable
1782   interpretation of AppleTalk-in-UDP).
1783
1784 - The grammar has undergone substantial changes (if you have an
1785   earlier version of tcpdump, you should re-read the manual
1786   entry).
1787
1788   The most useful change is the addition of an expression
1789   syntax that lets you filter on arbitrary fields or values in the
1790   packet.  E.g., "ip[0] > 0x45" would print only packets with IP
1791   options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1792   packets.
1793
1794   The most painful change is that concatenation no longer means
1795   "and" -- e.g., you have to say "host foo and port bar" instead
1796   of "host foo port bar".  The up side to this down is that
1797   repeated qualifiers can be omitted, making most filter
1798   expressions shorter.  E.g., you can now say "ip host foo and
1799   (bar or baz)" to look at ip traffic between hosts foo and bar or
1800   between hosts foo and baz.  [The old way of saying this was "ip
1801   host foo and (ip host bar or ip host baz)".]
1802
1803 v2.0 Sun Jan 13 12:20:40 PST 1991
1804
1805 - Initial public release.
