1146 autoconf version is broken (it only puts the library name in the
1147 cache variable name). Thanks to John Hawkinson.
1149 - Add a local autoconf macro to check for types; the autoconf version
1150 is broken (it uses grep instead of actually compiling a code fragment).

1207 Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
1209 - Rewrite ospf printer to improve truncation checks.

1212 (davids@secnet.com). Also, check tcp options to make sure they ar
1213 actually in the tcp header (in addition to the normal truncation
1214 checks). Fix the SACK code to print the N blocks (instead of the
1215 first block N times).
1217 - Don't say really small UDP packets are truncated just because they
1218 aren't big enough to be a RPC. As noted by David Sacerdote.
1220 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1222 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1225 - Print mtu for icmp unreach need frag packets. Thanks to John
1226 Hawkinson (jhawk@mit.edu)
1228 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1231 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1232 (kushida@trl.ibm.co.jp)
1234 - Check igmp checksum if possible. Thanks to John Hawkinson.
1236 - Made changes for SINIX. Thanks to Andrej Borsenkow

1251 signal() has different semantics on these systems.
1253 - Fixed some more alignment problems on the alpha.
1255 - Add code to massage unprintable characters in the domain and ipx
1256 printers. Thanks to John Hawkinson.

1366 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1369 - Don't checksum ip header if we don't have all of it. Thanks to John
1370 Hawkinson (jhawk@mit.edu).
1372 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1373 Honig (jhc@bsdi.com)
1376 v3.1a1 Wed May 3 19:21:11 PDT 1995
1378 - Include time.h when SVR4 is defined to avoid problems under Solaris
1381 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1382 strings, not the local buffer. Thanks to Stefan Petri
1383 (petri@ibr.cs.tu-bs.de).
1385 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1386 that the selected value was not used. Thanks to Pascal Hennequin
1387 (Pascal.Hennequin@hugo.int-evry.fr).
1389 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1391 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1393 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1395 - Although there never was a 3.0.3 release, the linux boys cleverly
1396 "released" one in late 1995.
1398 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1400 - Change configuration to not use gcc v2 flags with gcc v1.
1402 - Redo gmt2local() so that it works under BSDI (which seems to return
1403 an empty timezone struct from gettimeofday()). Based on report from
1404 Terry Kennedy (terry@spcvxa.spc.edu).
1406 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1407 on report from Mark Andrews (mandrews@alias.com).
1409 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1410 Orth (ro@techfak.uni-bielefeld.de).
1412 - Fixed printout of connection id for uncompressed tcp slip packets.
1413 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1415 - Hack around deficiency in Ultrix's make.
1417 - Add ETHERTYPE_TRAIL define which is missing from irix5.
1419 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1421 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1423 v3.0 Mon Jun 20 19:23:27 PDT 1994
1425 - Added support for printing tcp option timestamps thanks to
1426 Mark Andrews (mandrews@alias.com).
1428 - Reorganize protocol dumpers to take const pointers to packets so they
1429 never change the contents (i.e., they used to do endian conversions
1430 in place). Previously, whenever more than one pass was taken over
1431 the packet, the packet contents would be dumped incorrectly (i.e.,
1432 the output form -x would be wrong on little endian machines because
1433 the protocol dumpers would modify the data). Thanks to Charles Hannum
1434 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1436 - Added support for decnet protocol dumping thanks to Jeff Mogul
1439 - Fix bug that caused length of packet to be incorrectly printed
1440 (off by ether header size) for unknown ethernet types thanks
1441 to Greg Miller (gmiller@kayak.mitre.org).
1443 - Added support for IPX protocol dumping thanks to Brad Parker
1446 - Added check to verify IP header checksum under -v thanks to
1447 Brad Parker (brad@fcr.com).
1449 - Move packet capture code to new libpcap library (which is
1450 packaged separately).
1452 - Prototype everything and assume an ansi compiler.
1454 - print-arp.c: Print hardware ethernet addresses if they're not
1457 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1458 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1460 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1463 - print-icmp.c: Byte swap netmask before printing. Thanks to
1464 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1466 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1467 By default, only the inner packet is dumped, appended with the token
1468 "(encap)". Under -v, both the inner and output packets are dumped
1469 (on the same line). Note that the filter applies to the original packet,
1470 not the encapsulated packet. So if you run tcpdump on a net with an
1471 IP Multicast tunnel, you cannot filter out the datagrams using the
1472 conventional syntax. (You can filter away all the ip-in-ip traffic
1473 with "not ip proto 4".)
1475 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1476 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1478 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1480 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1481 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1482 Add && and || operators
1484 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1486 - Fix bug with -c flag.
1488 v2.2 Fri May 22 17:19:41 PDT 1992
1490 - savefile.c: Remove hack that shouldn't have been exported. Add
1493 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1494 matches non-echo/reply ICMP packets.
1496 - Many improvements to filter code optimizer.
1498 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1499 so that protocol qualifications are allowed. For example, "ip broadcast"
1500 and "ether multicast" are valid filters.
1502 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1503 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1504 patches to netinet/if_loop.c.
1506 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1507 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1509 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1511 v2.1 Tue Jan 28 11:00:14 PST 1992
1513 - Internal release (never publicly exported).
1515 v2.0.1 Sun Jan 26 21:10:10 PDT
1517 - Various byte ordering fixes.
1519 - Add truncation checks.
1521 - inet.c: Support BSD style SIOCGIFCONF.
1523 - nametoaddr.c: Handle multi addresses for single host.
1525 - optimize.c: Rewritten.
1527 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1530 - print-atal.c: Fix an alignment bug (thanks to
1531 stanonik@nprdc.navy.mil) Add missing printf() argument.
1533 - print-bootp.c: First attempt at decoding the vendor buffer.
1535 - print-domain.c: Fix truncation checks.
1537 - print-icmp.c: Calculate length of packets from the ip header.
1539 - print-ip.c: Print frag id in decimal (so it's easier to match up
1540 with non-frags). Add support for ospf, egp and igmp.
1542 - print-nfs.c: Lots of changes.
1544 - print-ntp.c: Make some verbose output depend on -v.
1546 - print-snmp.c: New version from John LoVerso.
1548 - print-tcp.c: Print rfc1072 tcp options.
1550 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1551 (microseconds) worth of precision. Fix uid bugs.
1553 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1554 With this option, you can create an architecture independent binary
1555 trace file in real time, without the overhead of the packet printer.
1556 At a later time, the packets can be filtered (again) and printed.
1558 - BSD is supported. You must have BPF in your kernel.
1559 Since the filtering is now done in the kernel, fewer packets are
1560 dropped. In fact, with BPF and the packet dumper option, a measly
1561 Sun 3/50 can keep up with a busy network.
1563 - Compressed SLIP packets can now be dumped, provided you use our
1564 SLIP software and BPF. These packets are dumped as any other IP
1565 packet; the compressed headers are dumped with the '-e' option.
1567 - Machines with little-endian byte ordering are supported (thanks to
1570 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1572 - IBM RT and Stanford Enetfilter support has been added by
1573 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1574 both the vanilla Enetfilter interface, and the extended interface
1575 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1577 - TFTP packets are now printed (requests only).
1579 - BOOTP packets are now printed.
1581 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1583 - Sparc architectures, including the Sparcstation-1, are now
1584 supported thanks to Steve McCanne and Craig Leres.
1586 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1587 University (micky@cunixc.cc.columbia.edu).
1589 - IP options are now printed.
1591 - RIP packets are now printed.
1593 - There's a -v flag that prints out more information than the
1594 default (e.g., it will enable printing of IP ttl, tos and id)
1595 and -q flag that prints out less (e.g., it will disable
1596 interpretation of AppleTalk-in-UDP).
1598 - The grammar has undergone substantial changes (if you have an
1599 earlier version of tcpdump, you should re-read the manual
1602 The most useful change is the addition of an expression
1603 syntax that lets you filter on arbitrary fields or values in the
1604 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1605 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1608 The most painful change is that concatenation no longer means
1609 "and" -- e.g., you have to say "host foo and port bar" instead
1610 of "host foo port bar". The up side to this down is that
1611 repeated qualifiers can be omitted, making most filter
1612 expressions shorter. E.g., you can now say "ip host foo and
1613 (bar or baz)" to look at ip traffic between hosts foo and bar or
1614 between hosts foo and baz. [The old way of saying this was "ip
1615 host foo and (ip host bar or ip host baz)".]
