1128 autoconf version is broken (it only puts the library name in the
1129 cache variable name). Thanks to John Hawkinson.
1131 - Add a local autoconf macro to check for types; the autoconf version
1132 is broken (it uses grep instead of actually compiling a code fragment).

1194 (davids@secnet.com). Also, check tcp options to make sure they ar
1195 actually in the tcp header (in addition to the normal truncation
1196 checks). Fix the SACK code to print the N blocks (instead of the
1197 first block N times).
1199 - Don't say really small UDP packets are truncated just because they
1200 aren't big enough to be a RPC. As noted by David Sacerdote.
1202 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1204 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1207 - Print mtu for icmp unreach need frag packets. Thanks to John
1208 Hawkinson (jhawk@mit.edu)
1210 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1213 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1214 (kushida@trl.ibm.co.jp)
1216 - Check igmp checksum if possible. Thanks to John Hawkinson.
1218 - Made changes for SINIX. Thanks to Andrej Borsenkow

1233 signal() has different semantics on these systems.
1235 - Fixed some more alignment problems on the alpha.
1237 - Add code to massage unprintable characters in the domain and ipx
1238 printers. Thanks to John Hawkinson.

1352 Hawkinson (jhawk@mit.edu).
1354 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1355 Honig (jhc@bsdi.com)
1358 v3.1a1 Wed May 3 19:21:11 PDT 1995
1360 - Include time.h when SVR4 is defined to avoid problems under Solaris
1363 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1364 strings, not the local buffer. Thanks to Stefan Petri
1365 (petri@ibr.cs.tu-bs.de).
1367 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1368 that the selected value was not used. Thanks to Pascal Hennequin
1369 (Pascal.Hennequin@hugo.int-evry.fr).
1371 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1373 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1375 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1377 - Although there never was a 3.0.3 release, the linux boys cleverly
1378 "released" one in late 1995.
1380 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1382 - Change configuration to not use gcc v2 flags with gcc v1.
1384 - Redo gmt2local() so that it works under BSDI (which seems to return
1385 an empty timezone struct from gettimeofday()). Based on report from
1386 Terry Kennedy (terry@spcvxa.spc.edu).
1388 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1389 on report from Mark Andrews (mandrews@alias.com).
1391 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1392 Orth (ro@techfak.uni-bielefeld.de).
1394 - Fixed printout of connection id for uncompressed tcp slip packets.
1395 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1397 - Hack around deficiency in Ultrix's make.

1401 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1403 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1405 v3.0 Mon Jun 20 19:23:27 PDT 1994
1407 - Added support for printing tcp option timestamps thanks to
1408 Mark Andrews (mandrews@alias.com).
1410 - Reorganize protocol dumpers to take const pointers to packets so they
1411 never change the contents (i.e., they used to do endian conversions
1412 in place). Previously, whenever more than one pass was taken over
1413 the packet, the packet contents would be dumped incorrectly (i.e.,
1414 the output form -x would be wrong on little endian machines because
1415 the protocol dumpers would modify the data). Thanks to Charles Hannum
1416 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1418 - Added support for decnet protocol dumping thanks to Jeff Mogul
1421 - Fix bug that caused length of packet to be incorrectly printed
1422 (off by ether header size) for unknown ethernet types thanks
1423 to Greg Miller (gmiller@kayak.mitre.org).
1425 - Added support for IPX protocol dumping thanks to Brad Parker
1428 - Added check to verify IP header checksum under -v thanks to
1429 Brad Parker (brad@fcr.com).
1431 - Move packet capture code to new libpcap library (which is
1432 packaged separately).
1434 - Prototype everything and assume an ansi compiler.
1436 - print-arp.c: Print hardware ethernet addresses if they're not
1439 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1440 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1442 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1445 - print-icmp.c: Byte swap netmask before printing. Thanks to
1446 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1448 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1449 By default, only the inner packet is dumped, appended with the token
1450 "(encap)". Under -v, both the inner and output packets are dumped
1451 (on the same line). Note that the filter applies to the original packet,
1452 not the encapsulated packet. So if you run tcpdump on a net with an
1453 IP Multicast tunnel, you cannot filter out the datagrams using the
1454 conventional syntax. (You can filter away all the ip-in-ip traffic
1455 with "not ip proto 4".)
1457 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1458 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1460 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1462 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1463 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1464 Add && and || operators
1466 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1468 - Fix bug with -c flag.
1470 v2.2 Fri May 22 17:19:41 PDT 1992
1472 - savefile.c: Remove hack that shouldn't have been exported. Add
1475 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1476 matches non-echo/reply ICMP packets.
1478 - Many improvements to filter code optimizer.
1480 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1481 so that protocol qualifications are allowed. For example, "ip broadcast"
1482 and "ether multicast" are valid filters.
1484 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1485 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1486 patches to netinet/if_loop.c.
1488 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1489 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1491 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1493 v2.1 Tue Jan 28 11:00:14 PST 1992
1495 - Internal release (never publicly exported).
1497 v2.0.1 Sun Jan 26 21:10:10 PDT
1499 - Various byte ordering fixes.
1501 - Add truncation checks.
1503 - inet.c: Support BSD style SIOCGIFCONF.
1505 - nametoaddr.c: Handle multi addresses for single host.
1507 - optimize.c: Rewritten.
1509 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1512 - print-atal.c: Fix an alignment bug (thanks to
1513 stanonik@nprdc.navy.mil) Add missing printf() argument.
1515 - print-bootp.c: First attempt at decoding the vendor buffer.
1517 - print-domain.c: Fix truncation checks.
1519 - print-icmp.c: Calculate length of packets from the ip header.
1521 - print-ip.c: Print frag id in decimal (so it's easier to match up
1522 with non-frags). Add support for ospf, egp and igmp.
1524 - print-nfs.c: Lots of changes.
1526 - print-ntp.c: Make some verbose output depend on -v.
1528 - print-snmp.c: New version from John LoVerso.
1530 - print-tcp.c: Print rfc1072 tcp options.
1532 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1533 (microseconds) worth of precision. Fix uid bugs.
1535 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1536 With this option, you can create an architecture independent binary
1537 trace file in real time, without the overhead of the packet printer.
1538 At a later time, the packets can be filtered (again) and printed.
1540 - BSD is supported. You must have BPF in your kernel.
1541 Since the filtering is now done in the kernel, fewer packets are
1542 dropped. In fact, with BPF and the packet dumper option, a measly
1543 Sun 3/50 can keep up with a busy network.
1545 - Compressed SLIP packets can now be dumped, provided you use our
1546 SLIP software and BPF. These packets are dumped as any other IP
1547 packet; the compressed headers are dumped with the '-e' option.
1549 - Machines with little-endian byte ordering are supported (thanks to
1552 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1554 - IBM RT and Stanford Enetfilter support has been added by
1555 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1556 both the vanilla Enetfilter interface, and the extended interface
1557 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1559 - TFTP packets are now printed (requests only).
1561 - BOOTP packets are now printed.
1563 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1565 - Sparc architectures, including the Sparcstation-1, are now
1566 supported thanks to Steve McCanne and Craig Leres.
1568 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1569 University (micky@cunixc.cc.columbia.edu).
1571 - IP options are now printed.
1573 - RIP packets are now printed.
1575 - There's a -v flag that prints out more information than the
1576 default (e.g., it will enable printing of IP ttl, tos and id)
1577 and -q flag that prints out less (e.g., it will disable
1578 interpretation of AppleTalk-in-UDP).
1580 - The grammar has undergone substantial changes (if you have an
1581 earlier version of tcpdump, you should re-read the manual
1584 The most useful change is the addition of an expression
1585 syntax that lets you filter on arbitrary fields or values in the
1586 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1587 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1590 The most painful change is that concatenation no longer means
1591 "and" -- e.g., you have to say "host foo and port bar" instead
1592 of "host foo port bar". The up side to this down is that
1593 repeated qualifiers can be omitted, making most filter
1594 expressions shorter. E.g., you can now say "ip host foo and
1595 (bar or baz)" to look at ip traffic between hosts foo and bar or
1596 between hosts foo and baz. [The old way of saying this was "ip
1597 host foo and (ip host bar or ip host baz)".]
1599 v2.0 Sun Jan 13 12:20:40 PST 1991
1601 - Initial public release.
