1137 autoconf version is broken (it only puts the library name in the
1138 cache variable name). Thanks to John Hawkinson.
1140 - Add a local autoconf macro to check for types; the autoconf version
1141 is broken (it uses grep instead of actually compiling a code fragment).
1143 - Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header

1203 (davids@secnet.com). Also, check tcp options to make sure they ar
1204 actually in the tcp header (in addition to the normal truncation
1205 checks). Fix the SACK code to print the N blocks (instead of the
1206 first block N times).
1208 - Don't say really small UDP packets are truncated just because they
1209 aren't big enough to be a RPC. As noted by David Sacerdote.
1211 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1213 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1216 - Print mtu for icmp unreach need frag packets. Thanks to John
1217 Hawkinson (jhawk@mit.edu)
1219 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1222 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1223 (kushida@trl.ibm.co.jp)
1225 - Check igmp checksum if possible. Thanks to John Hawkinson.
1227 - Made changes for SINIX. Thanks to Andrej Borsenkow

1242 signal() has different semantics on these systems.
1244 - Fixed some more alignment problems on the alpha.
1246 - Add code to massage unprintable characters in the domain and ipx
1247 printers. Thanks to John Hawkinson.

1309 - Port to GNU autoconf.
1311 - Add support for printing DVMRP and PIM traffic thanks to
1312 Havard Eidnes (Havard.Eidnes@runit.sintef.no).

1361 Hawkinson (jhawk@mit.edu).
1363 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1364 Honig (jhc@bsdi.com)
1367 v3.1a1 Wed May 3 19:21:11 PDT 1995
1369 - Include time.h when SVR4 is defined to avoid problems under Solaris
1372 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1373 strings, not the local buffer. Thanks to Stefan Petri
1374 (petri@ibr.cs.tu-bs.de).
1376 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1377 that the selected value was not used. Thanks to Pascal Hennequin
1378 (Pascal.Hennequin@hugo.int-evry.fr).
1380 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1382 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1384 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1386 - Although there never was a 3.0.3 release, the linux boys cleverly
1387 "released" one in late 1995.
1389 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1391 - Change configuration to not use gcc v2 flags with gcc v1.
1393 - Redo gmt2local() so that it works under BSDI (which seems to return
1394 an empty timezone struct from gettimeofday()). Based on report from
1395 Terry Kennedy (terry@spcvxa.spc.edu).
1397 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1398 on report from Mark Andrews (mandrews@alias.com).
1400 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1401 Orth (ro@techfak.uni-bielefeld.de).
1403 - Fixed printout of connection id for uncompressed tcp slip packets.
1404 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1406 - Hack around deficiency in Ultrix's make.

1410 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1412 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1414 v3.0 Mon Jun 20 19:23:27 PDT 1994
1416 - Added support for printing tcp option timestamps thanks to
1417 Mark Andrews (mandrews@alias.com).
1419 - Reorganize protocol dumpers to take const pointers to packets so they
1420 never change the contents (i.e., they used to do endian conversions
1421 in place). Previously, whenever more than one pass was taken over
1422 the packet, the packet contents would be dumped incorrectly (i.e.,
1423 the output form -x would be wrong on little endian machines because
1424 the protocol dumpers would modify the data). Thanks to Charles Hannum
1425 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1427 - Added support for decnet protocol dumping thanks to Jeff Mogul
1430 - Fix bug that caused length of packet to be incorrectly printed
1431 (off by ether header size) for unknown ethernet types thanks
1432 to Greg Miller (gmiller@kayak.mitre.org).
1434 - Added support for IPX protocol dumping thanks to Brad Parker
1437 - Added check to verify IP header checksum under -v thanks to
1438 Brad Parker (brad@fcr.com).
1440 - Move packet capture code to new libpcap library (which is
1441 packaged separately).
1443 - Prototype everything and assume an ansi compiler.
1445 - print-arp.c: Print hardware ethernet addresses if they're not
1448 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1449 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1451 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1454 - print-icmp.c: Byte swap netmask before printing. Thanks to
1455 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1457 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1458 By default, only the inner packet is dumped, appended with the token
1459 "(encap)". Under -v, both the inner and output packets are dumped
1460 (on the same line). Note that the filter applies to the original packet,
1461 not the encapsulated packet. So if you run tcpdump on a net with an
1462 IP Multicast tunnel, you cannot filter out the datagrams using the
1463 conventional syntax. (You can filter away all the ip-in-ip traffic
1464 with "not ip proto 4".)
1466 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1467 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1469 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1471 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1472 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1473 Add && and || operators
1475 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1477 - Fix bug with -c flag.
1479 v2.2 Fri May 22 17:19:41 PDT 1992
1481 - savefile.c: Remove hack that shouldn't have been exported. Add
1484 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1485 matches non-echo/reply ICMP packets.
1487 - Many improvements to filter code optimizer.
1489 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1490 so that protocol qualifications are allowed. For example, "ip broadcast"
1491 and "ether multicast" are valid filters.
1493 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1494 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1495 patches to netinet/if_loop.c.
1497 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1498 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1500 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1502 v2.1 Tue Jan 28 11:00:14 PST 1992
1504 - Internal release (never publicly exported).
1506 v2.0.1 Sun Jan 26 21:10:10 PDT
1508 - Various byte ordering fixes.
1510 - Add truncation checks.
1512 - inet.c: Support BSD style SIOCGIFCONF.
1514 - nametoaddr.c: Handle multi addresses for single host.
1516 - optimize.c: Rewritten.
1518 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1521 - print-atal.c: Fix an alignment bug (thanks to
1522 stanonik@nprdc.navy.mil) Add missing printf() argument.
1524 - print-bootp.c: First attempt at decoding the vendor buffer.
1526 - print-domain.c: Fix truncation checks.
1528 - print-icmp.c: Calculate length of packets from the ip header.
1530 - print-ip.c: Print frag id in decimal (so it's easier to match up
1531 with non-frags). Add support for ospf, egp and igmp.
1533 - print-nfs.c: Lots of changes.
1535 - print-ntp.c: Make some verbose output depend on -v.
1537 - print-snmp.c: New version from John LoVerso.
1539 - print-tcp.c: Print rfc1072 tcp options.
1541 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1542 (microseconds) worth of precision. Fix uid bugs.
1544 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1545 With this option, you can create an architecture independent binary
1546 trace file in real time, without the overhead of the packet printer.
1547 At a later time, the packets can be filtered (again) and printed.
1549 - BSD is supported. You must have BPF in your kernel.
1550 Since the filtering is now done in the kernel, fewer packets are
1551 dropped. In fact, with BPF and the packet dumper option, a measly
1552 Sun 3/50 can keep up with a busy network.
1554 - Compressed SLIP packets can now be dumped, provided you use our
1555 SLIP software and BPF. These packets are dumped as any other IP
1556 packet; the compressed headers are dumped with the '-e' option.
1558 - Machines with little-endian byte ordering are supported (thanks to
1561 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1563 - IBM RT and Stanford Enetfilter support has been added by
1564 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1565 both the vanilla Enetfilter interface, and the extended interface
1566 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1568 - TFTP packets are now printed (requests only).
1570 - BOOTP packets are now printed.
1572 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1574 - Sparc architectures, including the Sparcstation-1, are now
1575 supported thanks to Steve McCanne and Craig Leres.
1577 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1578 University (micky@cunixc.cc.columbia.edu).
1580 - IP options are now printed.
1582 - RIP packets are now printed.
1584 - There's a -v flag that prints out more information than the
1585 default (e.g., it will enable printing of IP ttl, tos and id)
1586 and -q flag that prints out less (e.g., it will disable
1587 interpretation of AppleTalk-in-UDP).
1589 - The grammar has undergone substantial changes (if you have an
1590 earlier version of tcpdump, you should re-read the manual
1593 The most useful change is the addition of an expression
1594 syntax that lets you filter on arbitrary fields or values in the
1595 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1596 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1599 The most painful change is that concatenation no longer means
1600 "and" -- e.g., you have to say "host foo and port bar" instead
1601 of "host foo port bar". The up side to this down is that
1602 repeated qualifiers can be omitted, making most filter
1603 expressions shorter. E.g., you can now say "ip host foo and
1604 (bar or baz)" to look at ip traffic between hosts foo and bar or
1605 between hosts foo and baz. [The old way of saying this was "ip
