1139 autoconf version is broken (it only puts the library name in the
1140 cache variable name). Thanks to John Hawkinson.
1142 - Add a local autoconf macro to check for types; the autoconf version
1143 is broken (it uses grep instead of actually compiling a code fragment).

1205 (davids@secnet.com). Also, check tcp options to make sure they ar
1206 actually in the tcp header (in addition to the normal truncation
1207 checks). Fix the SACK code to print the N blocks (instead of the
1208 first block N times).
1210 - Don't say really small UDP packets are truncated just because they
1211 aren't big enough to be a RPC. As noted by David Sacerdote.
1213 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1215 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1218 - Print mtu for icmp unreach need frag packets. Thanks to John
1219 Hawkinson (jhawk@mit.edu)
1221 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1224 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1225 (kushida@trl.ibm.co.jp)
1227 - Check igmp checksum if possible. Thanks to John Hawkinson.
1229 - Made changes for SINIX. Thanks to Andrej Borsenkow

1244 signal() has different semantics on these systems.
1246 - Fixed some more alignment problems on the alpha.
1248 - Add code to massage unprintable characters in the domain and ipx
1249 printers. Thanks to John Hawkinson.

1363 Hawkinson (jhawk@mit.edu).
1365 - Print out hostnames if possible in egp printer. Thanks to Jeffrey
1366 Honig (jhc@bsdi.com)
1369 v3.1a1 Wed May 3 19:21:11 PDT 1995
1371 - Include time.h when SVR4 is defined to avoid problems under Solaris
1374 - Fix etheraddr_string() in the ETHER_SERVICE to return the saved
1375 strings, not the local buffer. Thanks to Stefan Petri
1376 (petri@ibr.cs.tu-bs.de).
1378 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1379 that the selected value was not used. Thanks to Pascal Hennequin
1380 (Pascal.Hennequin@hugo.int-evry.fr).
1382 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1384 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1386 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1388 - Although there never was a 3.0.3 release, the linux boys cleverly
1389 "released" one in late 1995.
1391 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1393 - Change configuration to not use gcc v2 flags with gcc v1.
1395 - Redo gmt2local() so that it works under BSDI (which seems to return
1396 an empty timezone struct from gettimeofday()). Based on report from
1397 Terry Kennedy (terry@spcvxa.spc.edu).
1399 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1400 on report from Mark Andrews (mandrews@alias.com).
1402 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1403 Orth (ro@techfak.uni-bielefeld.de).
1405 - Fixed printout of connection id for uncompressed tcp slip packets.
1406 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1408 - Hack around deficiency in Ultrix's make.

1412 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1414 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1416 v3.0 Mon Jun 20 19:23:27 PDT 1994
1418 - Added support for printing tcp option timestamps thanks to
1419 Mark Andrews (mandrews@alias.com).
1421 - Reorganize protocol dumpers to take const pointers to packets so they
1422 never change the contents (i.e., they used to do endian conversions
1423 in place). Previously, whenever more than one pass was taken over
1424 the packet, the packet contents would be dumped incorrectly (i.e.,
1425 the output form -x would be wrong on little endian machines because
1426 the protocol dumpers would modify the data). Thanks to Charles Hannum
1427 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1429 - Added support for decnet protocol dumping thanks to Jeff Mogul
1432 - Fix bug that caused length of packet to be incorrectly printed
1433 (off by ether header size) for unknown ethernet types thanks
1434 to Greg Miller (gmiller@kayak.mitre.org).
1436 - Added support for IPX protocol dumping thanks to Brad Parker
1439 - Added check to verify IP header checksum under -v thanks to
1440 Brad Parker (brad@fcr.com).
1442 - Move packet capture code to new libpcap library (which is
1443 packaged separately).
1445 - Prototype everything and assume an ansi compiler.
1447 - print-arp.c: Print hardware ethernet addresses if they're not
1450 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1451 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1453 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1456 - print-icmp.c: Byte swap netmask before printing. Thanks to
1457 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1459 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1460 By default, only the inner packet is dumped, appended with the token
1461 "(encap)". Under -v, both the inner and output packets are dumped
1462 (on the same line). Note that the filter applies to the original packet,
1463 not the encapsulated packet. So if you run tcpdump on a net with an
1464 IP Multicast tunnel, you cannot filter out the datagrams using the
1465 conventional syntax. (You can filter away all the ip-in-ip traffic
1466 with "not ip proto 4".)
1468 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1469 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1471 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1473 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1474 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1475 Add && and || operators
1477 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1479 - Fix bug with -c flag.
1481 v2.2 Fri May 22 17:19:41 PDT 1992
1483 - savefile.c: Remove hack that shouldn't have been exported. Add
1486 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1487 matches non-echo/reply ICMP packets.
1489 - Many improvements to filter code optimizer.
1491 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1492 so that protocol qualifications are allowed. For example, "ip broadcast"
1493 and "ether multicast" are valid filters.
1495 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1496 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1497 patches to netinet/if_loop.c.
1499 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1500 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1502 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1504 v2.1 Tue Jan 28 11:00:14 PST 1992
1506 - Internal release (never publicly exported).
1508 v2.0.1 Sun Jan 26 21:10:10 PDT
1510 - Various byte ordering fixes.
1512 - Add truncation checks.
1514 - inet.c: Support BSD style SIOCGIFCONF.
1516 - nametoaddr.c: Handle multi addresses for single host.
1518 - optimize.c: Rewritten.
1520 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1523 - print-atal.c: Fix an alignment bug (thanks to
1524 stanonik@nprdc.navy.mil) Add missing printf() argument.
1526 - print-bootp.c: First attempt at decoding the vendor buffer.
1528 - print-domain.c: Fix truncation checks.
1530 - print-icmp.c: Calculate length of packets from the ip header.
1532 - print-ip.c: Print frag id in decimal (so it's easier to match up
1533 with non-frags). Add support for ospf, egp and igmp.
1535 - print-nfs.c: Lots of changes.
1537 - print-ntp.c: Make some verbose output depend on -v.
1539 - print-snmp.c: New version from John LoVerso.
1541 - print-tcp.c: Print rfc1072 tcp options.
1543 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1544 (microseconds) worth of precision. Fix uid bugs.
1546 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1547 With this option, you can create an architecture independent binary
1548 trace file in real time, without the overhead of the packet printer.
1549 At a later time, the packets can be filtered (again) and printed.
1551 - BSD is supported. You must have BPF in your kernel.
1552 Since the filtering is now done in the kernel, fewer packets are
1553 dropped. In fact, with BPF and the packet dumper option, a measly
1554 Sun 3/50 can keep up with a busy network.
1556 - Compressed SLIP packets can now be dumped, provided you use our
1557 SLIP software and BPF. These packets are dumped as any other IP
1558 packet; the compressed headers are dumped with the '-e' option.
1560 - Machines with little-endian byte ordering are supported (thanks to
1563 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1565 - IBM RT and Stanford Enetfilter support has been added by
1566 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1567 both the vanilla Enetfilter interface, and the extended interface
1568 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1570 - TFTP packets are now printed (requests only).
1572 - BOOTP packets are now printed.
1574 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1576 - Sparc architectures, including the Sparcstation-1, are now
1577 supported thanks to Steve McCanne and Craig Leres.
1579 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1580 University (micky@cunixc.cc.columbia.edu).
1582 - IP options are now printed.
1584 - RIP packets are now printed.
1586 - There's a -v flag that prints out more information than the
1587 default (e.g., it will enable printing of IP ttl, tos and id)
1588 and -q flag that prints out less (e.g., it will disable
1589 interpretation of AppleTalk-in-UDP).
1591 - The grammar has undergone substantial changes (if you have an
1592 earlier version of tcpdump, you should re-read the manual
1595 The most useful change is the addition of an expression
1596 syntax that lets you filter on arbitrary fields or values in the
1597 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1598 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1601 The most painful change is that concatenation no longer means
1602 "and" -- e.g., you have to say "host foo and port bar" instead
1603 of "host foo port bar". The up side to this down is that
1604 repeated qualifiers can be omitted, making most filter
1605 expressions shorter. E.g., you can now say "ip host foo and
1606 (bar or baz)" to look at ip traffic between hosts foo and bar or
