1134 autoconf version is broken (it only puts the library name in the
1135 cache variable name). Thanks to John Hawkinson.
1137 - Add a local autoconf macro to check for types; the autoconf version
1138 is broken (it uses grep instead of actually compiling a code fragment).

1200 (davids@secnet.com). Also, check tcp options to make sure they ar
1201 actually in the tcp header (in addition to the normal truncation
1202 checks). Fix the SACK code to print the N blocks (instead of the
1203 first block N times).
1205 - Don't say really small UDP packets are truncated just because they
1206 aren't big enough to be a RPC. As noted by David Sacerdote.
1208 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1210 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1213 - Print mtu for icmp unreach need frag packets. Thanks to John
1214 Hawkinson (jhawk@mit.edu)
1216 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1219 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1220 (kushida@trl.ibm.co.jp)
1222 - Check igmp checksum if possible. Thanks to John Hawkinson.
1224 - Made changes for SINIX. Thanks to Andrej Borsenkow

1239 signal() has different semantics on these systems.
1241 - Fixed some more alignment problems on the alpha.
1243 - Add code to massage unprintable characters in the domain and ipx
1244 printers. Thanks to John Hawkinson.

1358 Hawkinson (jhawk@mit.edu).
1360 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1361 Honig (jhc@bsdi.com)
1364 v3.1a1 Wed May 3 19:21:11 PDT 1995
1366 - Include time.h when SVR4 is defined to avoid problems under Solaris
1369 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1370 strings, not the local buffer. Thanks to Stefan Petri
1371 (petri@ibr.cs.tu-bs.de).
1373 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1374 that the selected value was not used. Thanks to Pascal Hennequin
1375 (Pascal.Hennequin@hugo.int-evry.fr).
1377 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1379 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1381 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1383 - Although there never was a 3.0.3 release, the linux boys cleverly
1384 "released" one in late 1995.
1386 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1388 - Change configuration to not use gcc v2 flags with gcc v1.
1390 - Redo gmt2local() so that it works under BSDI (which seems to return
1391 an empty timezone struct from gettimeofday()). Based on report from
1392 Terry Kennedy (terry@spcvxa.spc.edu).
1394 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1395 on report from Mark Andrews (mandrews@alias.com).
1397 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1398 Orth (ro@techfak.uni-bielefeld.de).
1400 - Fixed printout of connection id for uncompressed tcp slip packets.
1401 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1403 - Hack around deficiency in Ultrix's make.

1407 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1409 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1411 v3.0 Mon Jun 20 19:23:27 PDT 1994
1413 - Added support for printing tcp option timestamps thanks to
1414 Mark Andrews (mandrews@alias.com).
1416 - Reorganize protocol dumpers to take const pointers to packets so they
1417 never change the contents (i.e., they used to do endian conversions
1418 in place). Previously, whenever more than one pass was taken over
1419 the packet, the packet contents would be dumped incorrectly (i.e.,
1420 the output form -x would be wrong on little endian machines because
1421 the protocol dumpers would modify the data). Thanks to Charles Hannum
1422 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1424 - Added support for decnet protocol dumping thanks to Jeff Mogul
1427 - Fix bug that caused length of packet to be incorrectly printed
1428 (off by ether header size) for unknown ethernet types thanks
1429 to Greg Miller (gmiller@kayak.mitre.org).
1431 - Added support for IPX protocol dumping thanks to Brad Parker
1434 - Added check to verify IP header checksum under -v thanks to
1435 Brad Parker (brad@fcr.com).
1437 - Move packet capture code to new libpcap library (which is
1438 packaged separately).
1440 - Prototype everything and assume an ansi compiler.
1442 - print-arp.c: Print hardware ethernet addresses if they're not
1445 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1446 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1448 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1451 - print-icmp.c: Byte swap netmask before printing. Thanks to
1452 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1454 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1455 By default, only the inner packet is dumped, appended with the token
1456 "(encap)". Under -v, both the inner and output packets are dumped
1457 (on the same line). Note that the filter applies to the original packet,
1458 not the encapsulated packet. So if you run tcpdump on a net with an
1459 IP Multicast tunnel, you cannot filter out the datagrams using the
1460 conventional syntax. (You can filter away all the ip-in-ip traffic
1461 with "not ip proto 4".)
1463 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1464 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1466 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1468 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1469 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1470 Add && and || operators
1472 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1474 - Fix bug with -c flag.
1476 v2.2 Fri May 22 17:19:41 PDT 1992
1478 - savefile.c: Remove hack that shouldn't have been exported. Add
1481 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1482 matches non-echo/reply ICMP packets.
1484 - Many improvements to filter code optimizer.
1486 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1487 so that protocol qualifications are allowed. For example, "ip broadcast"
1488 and "ether multicast" are valid filters.
1490 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1491 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1492 patches to netinet/if_loop.c.
1494 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1495 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1497 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1499 v2.1 Tue Jan 28 11:00:14 PST 1992
1501 - Internal release (never publicly exported).
1503 v2.0.1 Sun Jan 26 21:10:10 PDT
1505 - Various byte ordering fixes.
1507 - Add truncation checks.
1509 - inet.c: Support BSD style SIOCGIFCONF.
1511 - nametoaddr.c: Handle multi addresses for single host.
1513 - optimize.c: Rewritten.
1515 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1518 - print-atal.c: Fix an alignment bug (thanks to
1519 stanonik@nprdc.navy.mil) Add missing printf() argument.
1521 - print-bootp.c: First attempt at decoding the vendor buffer.
1523 - print-domain.c: Fix truncation checks.
1525 - print-icmp.c: Calculate length of packets from the ip header.
1527 - print-ip.c: Print frag id in decimal (so it's easier to match up
1528 with non-frags). Add support for ospf, egp and igmp.
1530 - print-nfs.c: Lots of changes.
1532 - print-ntp.c: Make some verbose output depend on -v.
1534 - print-snmp.c: New version from John LoVerso.
1536 - print-tcp.c: Print rfc1072 tcp options.
1538 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1539 (microseconds) worth of precision. Fix uid bugs.
1541 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1542 With this option, you can create an architecture independent binary
1543 trace file in real time, without the overhead of the packet printer.
1544 At a later time, the packets can be filtered (again) and printed.
1546 - BSD is supported. You must have BPF in your kernel.
1547 Since the filtering is now done in the kernel, fewer packets are
1548 dropped. In fact, with BPF and the packet dumper option, a measly
1549 Sun 3/50 can keep up with a busy network.
1551 - Compressed SLIP packets can now be dumped, provided you use our
1552 SLIP software and BPF. These packets are dumped as any other IP
1553 packet; the compressed headers are dumped with the '-e' option.
1555 - Machines with little-endian byte ordering are supported (thanks to
1558 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1560 - IBM RT and Stanford Enetfilter support has been added by
1561 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1562 both the vanilla Enetfilter interface, and the extended interface
1563 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1565 - TFTP packets are now printed (requests only).
1567 - BOOTP packets are now printed.
1569 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1571 - Sparc architectures, including the Sparcstation-1, are now
1572 supported thanks to Steve McCanne and Craig Leres.
1574 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1575 University (micky@cunixc.cc.columbia.edu).
1577 - IP options are now printed.
1579 - RIP packets are now printed.
1581 - There's a -v flag that prints out more information than the
1582 default (e.g., it will enable printing of IP ttl, tos and id)
1583 and -q flag that prints out less (e.g., it will disable
1584 interpretation of AppleTalk-in-UDP).
1586 - The grammar has undergone substantial changes (if you have an
1587 earlier version of tcpdump, you should re-read the manual
1590 The most useful change is the addition of an expression
1591 syntax that lets you filter on arbitrary fields or values in the
1592 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1593 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1596 The most painful change is that concatenation no longer means
1597 "and" -- e.g., you have to say "host foo and port bar" instead
1598 of "host foo port bar". The up side to this down is that
1599 repeated qualifiers can be omitted, making most filter
1600 expressions shorter. E.g., you can now say "ip host foo and
1601 (bar or baz)" to look at ip traffic between hosts foo and bar or
1602 between hosts foo and baz. [The old way of saying this was "ip
1603 host foo and (ip host bar or ip host baz)".]
1605 v2.0 Sun Jan 13 12:20:40 PST 1991
1607 - Initial public release.
