1171 autoconf version is broken (it only puts the library name in the
1172 cache variable name). Thanks to John Hawkinson.
1174 - Add a local autoconf macro to check for types; the autoconf version
1175 is broken (it uses grep instead of actually compiling a code fragment).

1237 (davids@secnet.com). Also, check tcp options to make sure they ar
1238 actually in the tcp header (in addition to the normal truncation
1239 checks). Fix the SACK code to print the N blocks (instead of the
1240 first block N times).
1242 - Don't say really small UDP packets are truncated just because they
1243 aren't big enough to be a RPC. As noted by David Sacerdote.
1245 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1247 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1250 - Print mtu for icmp unreach need frag packets. Thanks to John
1251 Hawkinson (jhawk@mit.edu)

1256 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1257 (kushida@trl.ibm.co.jp)
1259 - Check igmp checksum if possible. Thanks to John Hawkinson.

1385 selective acknowledgment case.
1387 - Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig

1391 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1394 - Don't checksum ip header if we don't have all of it. Thanks to John
1395 Hawkinson (jhawk@mit.edu).

1403 - Include time.h when SVR4 is defined to avoid problems under Solaris
1406 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1407 strings, not the local buffer. Thanks to Stefan Petri
1408 (petri@ibr.cs.tu-bs.de).
1410 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1411 that the selected value was not used. Thanks to Pascal Hennequin
1412 (Pascal.Hennequin@hugo.int-evry.fr).
1414 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1416 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1418 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1420 - Although there never was a 3.0.3 release, the linux boys cleverly
1421 "released" one in late 1995.
1423 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1425 - Change configuration to not use gcc v2 flags with gcc v1.
1427 - Redo gmt2local() so that it works under BSDI (which seems to return
1428 an empty timezone struct from gettimeofday()). Based on report from
1429 Terry Kennedy (terry@spcvxa.spc.edu).
1431 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1432 on report from Mark Andrews (mandrews@alias.com).
1434 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1435 Orth (ro@techfak.uni-bielefeld.de).
1437 - Fixed printout of connection id for uncompressed tcp slip packets.
1438 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1440 - Hack around deficiency in Ultrix's make.

1444 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1446 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1448 v3.0 Mon Jun 20 19:23:27 PDT 1994
1450 - Added support for printing tcp option timestamps thanks to
1451 Mark Andrews (mandrews@alias.com).
1453 - Reorganize protocol dumpers to take const pointers to packets so they
1454 never change the contents (i.e., they used to do endian conversions
1455 in place). Previously, whenever more than one pass was taken over
1456 the packet, the packet contents would be dumped incorrectly (i.e.,
1457 the output form -x would be wrong on little endian machines because
1458 the protocol dumpers would modify the data). Thanks to Charles Hannum
1459 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1461 - Added support for decnet protocol dumping thanks to Jeff Mogul
1464 - Fix bug that caused length of packet to be incorrectly printed
1465 (off by ether header size) for unknown ethernet types thanks
1466 to Greg Miller (gmiller@kayak.mitre.org).
1468 - Added support for IPX protocol dumping thanks to Brad Parker
1471 - Added check to verify IP header checksum under -v thanks to
1472 Brad Parker (brad@fcr.com).
1474 - Move packet capture code to new libpcap library (which is
1475 packaged separately).
1477 - Prototype everything and assume an ansi compiler.
1479 - print-arp.c: Print hardware ethernet addresses if they're not
1482 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1483 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1485 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1488 - print-icmp.c: Byte swap netmask before printing. Thanks to
1489 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1491 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1492 By default, only the inner packet is dumped, appended with the token
1493 "(encap)". Under -v, both the inner and output packets are dumped
1494 (on the same line). Note that the filter applies to the original packet,
1495 not the encapsulated packet. So if you run tcpdump on a net with an
1496 IP Multicast tunnel, you cannot filter out the datagrams using the
1497 conventional syntax. (You can filter away all the ip-in-ip traffic
1498 with "not ip proto 4".)
1500 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1501 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1503 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1505 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1506 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1507 Add && and || operators
1509 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1511 - Fix bug with -c flag.
1513 v2.2 Fri May 22 17:19:41 PDT 1992
1515 - savefile.c: Remove hack that shouldn't have been exported. Add
1518 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1519 matches non-echo/reply ICMP packets.
1521 - Many improvements to filter code optimizer.
1523 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1524 so that protocol qualifications are allowed. For example, "ip broadcast"
1525 and "ether multicast" are valid filters.
1527 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1528 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1529 patches to netinet/if_loop.c.
1531 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1532 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1534 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1536 v2.1 Tue Jan 28 11:00:14 PST 1992
1538 - Internal release (never publicly exported).
1540 v2.0.1 Sun Jan 26 21:10:10 PDT
1542 - Various byte ordering fixes.
1544 - Add truncation checks.
1546 - inet.c: Support BSD style SIOCGIFCONF.
1548 - nametoaddr.c: Handle multi addresses for single host.
1550 - optimize.c: Rewritten.
1552 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1555 - print-atal.c: Fix an alignment bug (thanks to
1556 stanonik@nprdc.navy.mil) Add missing printf() argument.
1558 - print-bootp.c: First attempt at decoding the vendor buffer.
1560 - print-domain.c: Fix truncation checks.
1562 - print-icmp.c: Calculate length of packets from the ip header.
1564 - print-ip.c: Print frag id in decimal (so it's easier to match up
1565 with non-frags). Add support for ospf, egp and igmp.
1567 - print-nfs.c: Lots of changes.
1569 - print-ntp.c: Make some verbose output depend on -v.
1571 - print-snmp.c: New version from John LoVerso.
1573 - print-tcp.c: Print rfc1072 tcp options.
1575 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1576 (microseconds) worth of precision. Fix uid bugs.
1578 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1579 With this option, you can create an architecture independent binary
1580 trace file in real time, without the overhead of the packet printer.
1581 At a later time, the packets can be filtered (again) and printed.
1583 - BSD is supported. You must have BPF in your kernel.
1584 Since the filtering is now done in the kernel, fewer packets are
1585 dropped. In fact, with BPF and the packet dumper option, a measly
1586 Sun 3/50 can keep up with a busy network.
1588 - Compressed SLIP packets can now be dumped, provided you use our
1589 SLIP software and BPF. These packets are dumped as any other IP
1590 packet; the compressed headers are dumped with the '-e' option.
1592 - Machines with little-endian byte ordering are supported (thanks to
1595 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1597 - IBM RT and Stanford Enetfilter support has been added by
1598 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1599 both the vanilla Enetfilter interface, and the extended interface
1600 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1602 - TFTP packets are now printed (requests only).
1604 - BOOTP packets are now printed.
1606 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1608 - Sparc architectures, including the Sparcstation-1, are now
1609 supported thanks to Steve McCanne and Craig Leres.
1611 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1612 University (micky@cunixc.cc.columbia.edu).
1614 - IP options are now printed.
1616 - RIP packets are now printed.
1618 - There's a -v flag that prints out more information than the
1619 default (e.g., it will enable printing of IP ttl, tos and id)
1620 and -q flag that prints out less (e.g., it will disable
1621 interpretation of AppleTalk-in-UDP).
1623 - The grammar has undergone substantial changes (if you have an
1624 earlier version of tcpdump, you should re-read the manual
1627 The most useful change is the addition of an expression
1628 syntax that lets you filter on arbitrary fields or values in the
1629 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1630 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1633 The most painful change is that concatenation no longer means
1634 "and" -- e.g., you have to say "host foo and port bar" instead
1635 of "host foo port bar". The up side to this down is that
1636 repeated qualifiers can be omitted, making most filter
1637 expressions shorter. E.g., you can now say "ip host foo and
1638 (bar or baz)" to look at ip traffic between hosts foo and bar or
1639 between hosts foo and baz. [The old way of saying this was "ip
1640 host foo and (ip host bar or ip host baz)".]
