1143 autoconf version is broken (it only puts the library name in the
1144 cache variable name). Thanks to John Hawkinson.
1146 - Add a local autoconf macro to check for types; the autoconf version
1147 is broken (it uses grep instead of actually compiling a code fragment).

1209 (davids@secnet.com). Also, check tcp options to make sure they ar
1210 actually in the tcp header (in addition to the normal truncation
1211 checks). Fix the SACK code to print the N blocks (instead of the
1212 first block N times).
1214 - Don't say really small UDP packets are truncated just because they
1215 aren't big enough to be a RPC. As noted by David Sacerdote.
1217 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1219 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1222 - Print mtu for icmp unreach need frag packets. Thanks to John
1223 Hawkinson (jhawk@mit.edu)
1225 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1228 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1229 (kushida@trl.ibm.co.jp)
1231 - Check igmp checksum if possible. Thanks to John Hawkinson.
1233 - Made changes for SINIX. Thanks to Andrej Borsenkow

1248 signal() has different semantics on these systems.
1250 - Fixed some more alignment problems on the alpha.
1252 - Add code to massage unprintable characters in the domain and ipx
1253 printers. Thanks to John Hawkinson.

1367 Hawkinson (jhawk@mit.edu).
1369 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1370 Honig (jhc@bsdi.com)
1373 v3.1a1 Wed May 3 19:21:11 PDT 1995
1375 - Include time.h when SVR4 is defined to avoid problems under Solaris
1378 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1379 strings, not the local buffer. Thanks to Stefan Petri
1380 (petri@ibr.cs.tu-bs.de).
1382 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1383 that the selected value was not used. Thanks to Pascal Hennequin
1384 (Pascal.Hennequin@hugo.int-evry.fr).
1386 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1388 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1390 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1392 - Although there never was a 3.0.3 release, the linux boys cleverly
1393 "released" one in late 1995.
1395 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1397 - Change configuration to not use gcc v2 flags with gcc v1.
1399 - Redo gmt2local() so that it works under BSDI (which seems to return
1400 an empty timezone struct from gettimeofday()). Based on report from
1401 Terry Kennedy (terry@spcvxa.spc.edu).
1403 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1404 on report from Mark Andrews (mandrews@alias.com).
1406 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1407 Orth (ro@techfak.uni-bielefeld.de).
1409 - Fixed printout of connection id for uncompressed tcp slip packets.
1410 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1412 - Hack around deficiency in Ultrix's make.

1416 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1418 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1420 v3.0 Mon Jun 20 19:23:27 PDT 1994
1422 - Added support for printing tcp option timestamps thanks to
1423 Mark Andrews (mandrews@alias.com).
1425 - Reorganize protocol dumpers to take const pointers to packets so they
1426 never change the contents (i.e., they used to do endian conversions
1427 in place). Previously, whenever more than one pass was taken over
1428 the packet, the packet contents would be dumped incorrectly (i.e.,
1429 the output form -x would be wrong on little endian machines because
1430 the protocol dumpers would modify the data). Thanks to Charles Hannum
1431 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1433 - Added support for decnet protocol dumping thanks to Jeff Mogul
1436 - Fix bug that caused length of packet to be incorrectly printed
1437 (off by ether header size) for unknown ethernet types thanks
1438 to Greg Miller (gmiller@kayak.mitre.org).
1440 - Added support for IPX protocol dumping thanks to Brad Parker
1443 - Added check to verify IP header checksum under -v thanks to
1444 Brad Parker (brad@fcr.com).
1446 - Move packet capture code to new libpcap library (which is
1447 packaged separately).
1449 - Prototype everything and assume an ansi compiler.
1451 - print-arp.c: Print hardware ethernet addresses if they're not
1454 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1455 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1457 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1460 - print-icmp.c: Byte swap netmask before printing. Thanks to
1461 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1463 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1464 By default, only the inner packet is dumped, appended with the token
1465 "(encap)". Under -v, both the inner and output packets are dumped
1466 (on the same line). Note that the filter applies to the original packet,
1467 not the encapsulated packet. So if you run tcpdump on a net with an
1468 IP Multicast tunnel, you cannot filter out the datagrams using the
1469 conventional syntax. (You can filter away all the ip-in-ip traffic
1470 with "not ip proto 4".)
1472 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1473 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1475 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1477 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1478 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1479 Add && and || operators
1481 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1483 - Fix bug with -c flag.
1485 v2.2 Fri May 22 17:19:41 PDT 1992
1487 - savefile.c: Remove hack that shouldn't have been exported. Add
1490 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1491 matches non-echo/reply ICMP packets.
1493 - Many improvements to filter code optimizer.
1495 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1496 so that protocol qualifications are allowed. For example, "ip broadcast"
1497 and "ether multicast" are valid filters.
1499 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1500 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1501 patches to netinet/if_loop.c.
1503 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1504 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1506 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1508 v2.1 Tue Jan 28 11:00:14 PST 1992
1510 - Internal release (never publicly exported).
1512 v2.0.1 Sun Jan 26 21:10:10 PDT
1514 - Various byte ordering fixes.
1516 - Add truncation checks.
1518 - inet.c: Support BSD style SIOCGIFCONF.
1520 - nametoaddr.c: Handle multi addresses for single host.
1522 - optimize.c: Rewritten.
1524 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1527 - print-atal.c: Fix an alignment bug (thanks to
1528 stanonik@nprdc.navy.mil) Add missing printf() argument.
1530 - print-bootp.c: First attempt at decoding the vendor buffer.
1532 - print-domain.c: Fix truncation checks.
1534 - print-icmp.c: Calculate length of packets from the ip header.
1536 - print-ip.c: Print frag id in decimal (so it's easier to match up
1537 with non-frags). Add support for ospf, egp and igmp.
1539 - print-nfs.c: Lots of changes.
1541 - print-ntp.c: Make some verbose output depend on -v.
1543 - print-snmp.c: New version from John LoVerso.
1545 - print-tcp.c: Print rfc1072 tcp options.
1547 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1548 (microseconds) worth of precision. Fix uid bugs.
1550 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1551 With this option, you can create an architecture independent binary
1552 trace file in real time, without the overhead of the packet printer.
1553 At a later time, the packets can be filtered (again) and printed.
1555 - BSD is supported. You must have BPF in your kernel.
1556 Since the filtering is now done in the kernel, fewer packets are
1557 dropped. In fact, with BPF and the packet dumper option, a measly
1558 Sun 3/50 can keep up with a busy network.
1560 - Compressed SLIP packets can now be dumped, provided you use our
1561 SLIP software and BPF. These packets are dumped as any other IP
1562 packet; the compressed headers are dumped with the '-e' option.
1564 - Machines with little-endian byte ordering are supported (thanks to
1567 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1569 - IBM RT and Stanford Enetfilter support has been added by
1570 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1571 both the vanilla Enetfilter interface, and the extended interface
1572 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1574 - TFTP packets are now printed (requests only).
1576 - BOOTP packets are now printed.
1578 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1580 - Sparc architectures, including the Sparcstation-1, are now
1581 supported thanks to Steve McCanne and Craig Leres.
1583 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1584 University (micky@cunixc.cc.columbia.edu).
1586 - IP options are now printed.
1588 - RIP packets are now printed.
1590 - There's a -v flag that prints out more information than the
1591 default (e.g., it will enable printing of IP ttl, tos and id)
1592 and -q flag that prints out less (e.g., it will disable
1593 interpretation of AppleTalk-in-UDP).
1595 - The grammar has undergone substantial changes (if you have an
1596 earlier version of tcpdump, you should re-read the manual
1599 The most useful change is the addition of an expression
1600 syntax that lets you filter on arbitrary fields or values in the
1601 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1602 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1605 The most painful change is that concatenation no longer means
1606 "and" -- e.g., you have to say "host foo and port bar" instead
1607 of "host foo port bar". The up side to this down is that
1608 repeated qualifiers can be omitted, making most filter
1609 expressions shorter. E.g., you can now say "ip host foo and
1610 (bar or baz)" to look at ip traffic between hosts foo and bar or
