1362   actually in the tcp header (in addition to the normal truncation
1363   checks). Fix the SACK code to print the N blocks (instead of the
1364   first block N times).
1365
1366 - Don't say really small UDP packets are truncated just because they
1367   aren't big enough to be a RPC. As noted by David Sacerdote.
1368
1369 v3.2.1 Sun Jul 14 03:02:26 PDT 1996

1395   Thanks to John Hawkinson.
1396
1397 - Added some more packet truncation checks.
1398
1399 - On systems that have it, use sigset() instead of signal() since

1440
1441 v3.2 Sun Jun 23 02:28:10 PDT 1996
1442
1443 - Print new icmp unreachable codes as suggested by Martin Fredriksson
1444   (martin@msp.se). Also print code value when unknown for icmp redirect

1446
1447 - Fix an alignment endian bug in getname(). Thanks to John Hawkinson.
1448
1449 - Define "new" domain record types if not found in arpa/nameserv.h.

1451   fixed an endian bug when printing mx record and added some new record
1452   types.
1453
1454 - Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
1455
1456 - Added T/TCP options printing. As suggested by Richard Stevens
1457   (rstevens@noao.edu)
1458
1459 - Use autoconf to detect architectures that can't handle misaligned
1460   accesses.
1461
1462 v3.1 Thu Jun 13 20:59:32 PDT 1996
1463
1464 - Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
1465   and bind (as suggested by Charles Hannum).
1466
1467 - Port to GNU autoconf.
1468
1469 - Add support for printing DVMRP and PIM traffic thanks to
1470   Havard Eidnes (Havard.Eidnes@runit.sintef.no).
1471
1472 - Fix AppleTalk, IPX and DECnet byte order problems due to wrong endian
1473   define being referenced. Reported by Terry Kennedy.
1474
1475 - Minor fixes to the man page thanks to Mark Andrews.
1476
1477 - Endian fixes to RTP and vat packet dumpers, thanks to Bruce Mah
1478   (bmah@cs.berkeley.edu).

1481
1482 - Fixed tftp_print() to print the block number for ACKs.
1483
1484 - Document -dd and -ddd. Resulted from a bug report from Charlie Slater
1485   (cslater@imatek.com).
1486
1487 - Check return status from malloc/calloc/etc.
1488
1489 - Check return status from pcap_loop() so we can print an error and
1490   exit with a bad status if there were problems.
1491
1492 - Bail if ip option length is <= 0. Resulted from a bug report from
1493   Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).
1494
1495 - Print out a little more information for sun rpc packets.
1496
1497 - Add support for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu).
1498
1499 - Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were
1500   wrong on little endian machines).
1501
1502 - Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
1503   (crawdad@fnal.gov).
1504
1505 - Fix ntp_print() to not print garbage when the stratum is
1506   "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).

1515   octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1516   (toku@dit.co.jp)
1517
1518 - Don't checksum ip header if we don't have all of it. Thanks to John
1519   Hawkinson (jhawk@mit.edu).
1520
1521 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1522   Honig (jhc@bsdi.com)
1523
1524
1525 v3.1a1 Wed May  3 19:21:11 PDT 1995
1526
1527 - Include time.h when SVR4 is defined to avoid problems under Solaris
1528   2.3.
1529
1530 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1531   strings, not the local buffer. Thanks to Stefan Petri
1532   (petri@ibr.cs.tu-bs.de).
1533
1534 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1535   that the selected value was not used. Thanks to Pascal Hennequin
1536   (Pascal.Hennequin@hugo.int-evry.fr).
1537
1538 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1539
1540 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1541
1542 v3.0.3 Sun Oct  1 18:35:00 GMT 1995
1543
1544 - Although there never was a 3.0.3 release, the linux boys cleverly
1545   "released" one in late 1995.
1546
1547 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1548
1549 - Change configuration to not use gcc v2 flags with gcc v1.
1550
1551 - Redo gmt2local() so that it works under BSDI (which seems to return
1552   an empty timezone struct from gettimeofday()). Based on report from
1553   Terry Kennedy (terry@spcvxa.spc.edu).
1554
1555 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1556   on report from Mark Andrews (mandrews@alias.com).
1557
1558 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1559   Orth (ro@techfak.uni-bielefeld.de).
1560
1561 - Fixed printout of connection id for uncompressed tcp slip packets.
1562   Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1563
1564 - Hack around deficiency in Ultrix's make.
1565
1566 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1567
1568 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1569
1570 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1571
1572 v3.0 Mon Jun 20 19:23:27 PDT 1994
1573
1574 - Added support for printing tcp option timestamps thanks to
1575   Mark Andrews (mandrews@alias.com).
1576
1577 - Reorganize protocol dumpers to take const pointers to packets so they
1578   never change the contents (i.e., they used to do endian conversions
1579   in place).  Previously, whenever more than one pass was taken over
1580   the packet, the packet contents would be dumped incorrectly (i.e.,
1581   the output form -x would be wrong on little endian machines because
1582   the protocol dumpers would modify the data).  Thanks to Charles Hannum
1583   (mycroft@gnu.ai.mit.edu) for reporting this problem.
1584
1585 - Added support for decnet protocol dumping thanks to Jeff Mogul
1586   (mogul@pa.dec.com).
1587
1588 - Fix bug that caused length of packet to be incorrectly printed
1589   (off by ether header size) for unknown ethernet types thanks
1590   to Greg Miller (gmiller@kayak.mitre.org).
1591
1592 - Added support for IPX protocol dumping thanks to Brad Parker
1593   (brad@fcr.com).
1594
1595 - Added check to verify IP header checksum under -v thanks to
1596   Brad Parker (brad@fcr.com).
1597
1598 - Move packet capture code to new libpcap library (which is
1599   packaged separately).
1600
1601 - Prototype everything and assume an ansi compiler.
1602
1603 - print-arp.c: Print hardware ethernet addresses if they're not
1604   what we expect.
1605
1606 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1607   Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1608
1609 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1610   (mogul@pa.dec.com).
1611
1612 - print-icmp.c: Byte swap netmask before printing. Thanks to
1613   Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1614
1615 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1616   By default, only the inner packet is dumped, appended with the token
1617   "(encap)".  Under -v, both the inner and output packets are dumped
1618   (on the same line).  Note that the filter applies to the original packet,
1619   not the encapsulated packet.  So if you run tcpdump on a net with an
1620   IP Multicast tunnel, you cannot filter out the datagrams using the
1621   conventional syntax.  (You can filter away all the ip-in-ip traffic
1622   with "not ip proto 4".)
1623
1624 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1625   nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1626
1627 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1628
1629 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1630   (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1631   Add && and || operators
1632
1633 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1634
1635 - Fix bug with -c flag.
1636
1637 v2.2 Fri May 22 17:19:41 PDT 1992
1638
1639 - savefile.c: Remove hack that shouldn't have been exported. Add
1640   truncate checks.
1641
1642 - Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
1643   matches non-echo/reply ICMP packets.
1644
1645 - Many improvements to filter code optimizer.
1646
1647 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1648   so that protocol qualifications are allowed. For example, "ip broadcast"
1649   and "ether multicast" are valid filters.
1650
1651 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1652   Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1653   patches to netinet/if_loop.c.
1654
1655 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1656   Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1657
1658 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1659
1660 v2.1 Tue Jan 28 11:00:14 PST 1992
1661
1662 - Internal release (never publicly exported).
1663
1664 v2.0.1 Sun Jan 26 21:10:10 PDT
1665
1666 - Various byte ordering fixes.
1667
1668 - Add truncation checks.
1669
1670 - inet.c: Support BSD style SIOCGIFCONF.
1671
1672 - nametoaddr.c: Handle multi addresses for single host.
1673
1674 - optimize.c: Rewritten.
1675
1676 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1677   for broadcast nets.
1678
1679 - print-atal.c: Fix an alignment bug (thanks to
1680   stanonik@nprdc.navy.mil) Add missing printf() argument.
1681
1682 - print-bootp.c: First attempt at decoding the vendor buffer.
1683
1684 - print-domain.c: Fix truncation checks.
1685
1686 - print-icmp.c: Calculate length of packets from the ip header.
1687
1688 - print-ip.c: Print frag id in decimal (so it's easier to match up
1689   with non-frags). Add support for ospf, egp and igmp.
1690
1691 - print-nfs.c: Lots of changes.
1692
1693 - print-ntp.c: Make some verbose output depend on -v.
1694
1695 - print-snmp.c: New version from John LoVerso.
1696
1697 - print-tcp.c: Print rfc1072 tcp options.
1698
1699 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1700   (microseconds) worth of precision. Fix uid bugs.
1701
1702 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1703   With this option, you can create an architecture independent binary
1704   trace file in real time, without the overhead of the packet printer.
1705   At a later time, the packets can be filtered (again) and printed.
1706
1707 - BSD is supported.  You must have BPF in your kernel.
1708   Since the filtering is now done in the kernel, fewer packets are
1709   dropped.  In fact, with BPF and the packet dumper option, a measly
1710   Sun 3/50 can keep up with a busy network.
1711
1712 - Compressed SLIP packets can now be dumped, provided you use our
1713   SLIP software and BPF.  These packets are dumped as any other IP
1714   packet; the compressed headers are dumped with the '-e' option.
1715
1716 - Machines with little-endian byte ordering are supported (thanks to
1717   Jeff Mogul).
1718
1719 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1720
1721 - IBM RT and Stanford Enetfilter support has been added by
1722   Rayan Zachariassen <rayan@canet.ca>.  Tcpdump has been tested under
1723   both the vanilla Enetfilter interface, and the extended interface
1724   (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1725
1726 - TFTP packets are now printed (requests only).
1727
1728 - BOOTP packets are now printed.
1729
1730 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1731
1732 - Sparc architectures, including the Sparcstation-1, are now
1733   supported thanks to Steve McCanne and Craig Leres.
1734
1735 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1736   University (micky@cunixc.cc.columbia.edu).
1737
1738 - IP options are now printed.
1739
1740 - RIP packets are now printed.
1741
1742 - There's a -v flag that prints out more information than the
1743   default (e.g., it will enable printing of IP ttl, tos and id)
1744   and -q flag that prints out less (e.g., it will disable
1745   interpretation of AppleTalk-in-UDP).
1746
1747 - The grammar has undergone substantial changes (if you have an
1748   earlier version of tcpdump, you should re-read the manual
1749   entry).
1750
1751   The most useful change is the addition of an expression
1752   syntax that lets you filter on arbitrary fields or values in the
1753   packet.  E.g., "ip[0] > 0x45" would print only packets with IP
1754   options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1755   packets.
1756
1757   The most painful change is that concatenation no longer means
1758   "and" -- e.g., you have to say "host foo and port bar" instead
1759   of "host foo port bar".  The up side to this down is that
1760   repeated qualifiers can be omitted, making most filter
1761   expressions shorter.  E.g., you can now say "ip host foo and
1762   (bar or baz)" to look at ip traffic between hosts foo and bar or
1763   between hosts foo and baz.  [The old way of saying this was "ip
1764   host foo and (ip host bar or ip host baz)".]
1765
1766 v2.0 Sun Jan 13 12:20:40 PST 1991
1767
1768 - Initial public release.
