1163 autoconf version is broken (it only puts the library name in the
1164 cache variable name). Thanks to John Hawkinson.
1166 - Add a local autoconf macro to check for types; the autoconf version
1167 is broken (it uses grep instead of actually compiling a code fragment).

1229 (davids@secnet.com). Also, check tcp options to make sure they ar
1230 actually in the tcp header (in addition to the normal truncation
1231 checks). Fix the SACK code to print the N blocks (instead of the
1232 first block N times).
1234 - Don't say really small UDP packets are truncated just because they
1235 aren't big enough to be a RPC. As noted by David Sacerdote.
1237 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1239 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1242 - Print mtu for icmp unreach need frag packets. Thanks to John
1243 Hawkinson (jhawk@mit.edu)

1248 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1249 (kushida@trl.ibm.co.jp)
1251 - Check igmp checksum if possible. Thanks to John Hawkinson.
1253 - Made changes for SINIX. Thanks to Andrej Borsenkow

1383 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1386 - Don't checksum ip header if we don't have all of it. Thanks to John
1387 Hawkinson (jhawk@mit.edu).

1399 strings, not the local buffer. Thanks to Stefan Petri
1400 (petri@ibr.cs.tu-bs.de).
1402 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1403 that the selected value was not used. Thanks to Pascal Hennequin

1406 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1408 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1410 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1412 - Although there never was a 3.0.3 release, the linux boys cleverly
1413 "released" one in late 1995.
1415 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1417 - Change configuration to not use gcc v2 flags with gcc v1.
1419 - Redo gmt2local() so that it works under BSDI (which seems to return
1420 an empty timezone struct from gettimeofday()). Based on report from
1421 Terry Kennedy (terry@spcvxa.spc.edu).
1423 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1424 on report from Mark Andrews (mandrews@alias.com).
1426 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1427 Orth (ro@techfak.uni-bielefeld.de).
1429 - Fixed printout of connection id for uncompressed tcp slip packets.
1430 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1432 - Hack around deficiency in Ultrix's make.

1436 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1438 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1440 v3.0 Mon Jun 20 19:23:27 PDT 1994
1442 - Added support for printing tcp option timestamps thanks to
1443 Mark Andrews (mandrews@alias.com).
1445 - Reorganize protocol dumpers to take const pointers to packets so they
1446 never change the contents (i.e., they used to do endian conversions
1447 in place). Previously, whenever more than one pass was taken over
1448 the packet, the packet contents would be dumped incorrectly (i.e.,
1449 the output form -x would be wrong on little endian machines because
1450 the protocol dumpers would modify the data). Thanks to Charles Hannum
1451 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1453 - Added support for decnet protocol dumping thanks to Jeff Mogul
1456 - Fix bug that caused length of packet to be incorrectly printed
1457 (off by ether header size) for unknown ethernet types thanks
1458 to Greg Miller (gmiller@kayak.mitre.org).
1460 - Added support for IPX protocol dumping thanks to Brad Parker
1463 - Added check to verify IP header checksum under -v thanks to
1464 Brad Parker (brad@fcr.com).
1466 - Move packet capture code to new libpcap library (which is
1467 packaged separately).
1469 - Prototype everything and assume an ansi compiler.
1471 - print-arp.c: Print hardware ethernet addresses if they're not
1474 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1475 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1477 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1480 - print-icmp.c: Byte swap netmask before printing. Thanks to
1481 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1483 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1484 By default, only the inner packet is dumped, appended with the token
1485 "(encap)". Under -v, both the inner and output packets are dumped
1486 (on the same line). Note that the filter applies to the original packet,
1487 not the encapsulated packet. So if you run tcpdump on a net with an
1488 IP Multicast tunnel, you cannot filter out the datagrams using the
1489 conventional syntax. (You can filter away all the ip-in-ip traffic
1490 with "not ip proto 4".)
1492 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1493 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1495 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1497 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1498 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1499 Add && and || operators
1501 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1503 - Fix bug with -c flag.
1505 v2.2 Fri May 22 17:19:41 PDT 1992
1507 - savefile.c: Remove hack that shouldn't have been exported. Add
1510 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1511 matches non-echo/reply ICMP packets.
1513 - Many improvements to filter code optimizer.
1515 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1516 so that protocol qualifications are allowed. For example, "ip broadcast"
1517 and "ether multicast" are valid filters.
1519 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1520 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1521 patches to netinet/if_loop.c.
1523 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1524 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1526 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1528 v2.1 Tue Jan 28 11:00:14 PST 1992
1530 - Internal release (never publicly exported).
1532 v2.0.1 Sun Jan 26 21:10:10 PDT
1534 - Various byte ordering fixes.
1536 - Add truncation checks.
1538 - inet.c: Support BSD style SIOCGIFCONF.
1540 - nametoaddr.c: Handle multi addresses for single host.
1542 - optimize.c: Rewritten.
1544 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1547 - print-atal.c: Fix an alignment bug (thanks to
1548 stanonik@nprdc.navy.mil) Add missing printf() argument.
1550 - print-bootp.c: First attempt at decoding the vendor buffer.
1552 - print-domain.c: Fix truncation checks.
1554 - print-icmp.c: Calculate length of packets from the ip header.
1556 - print-ip.c: Print frag id in decimal (so it's easier to match up
1557 with non-frags). Add support for ospf, egp and igmp.
1559 - print-nfs.c: Lots of changes.
1561 - print-ntp.c: Make some verbose output depend on -v.
1563 - print-snmp.c: New version from John LoVerso.
1565 - print-tcp.c: Print rfc1072 tcp options.
1567 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1568 (microseconds) worth of precision. Fix uid bugs.
1570 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1571 With this option, you can create an architecture independent binary
1572 trace file in real time, without the overhead of the packet printer.
1573 At a later time, the packets can be filtered (again) and printed.
1575 - BSD is supported. You must have BPF in your kernel.
1576 Since the filtering is now done in the kernel, fewer packets are
1577 dropped. In fact, with BPF and the packet dumper option, a measly
1578 Sun 3/50 can keep up with a busy network.
1580 - Compressed SLIP packets can now be dumped, provided you use our
1581 SLIP software and BPF. These packets are dumped as any other IP
1582 packet; the compressed headers are dumped with the '-e' option.
1584 - Machines with little-endian byte ordering are supported (thanks to
1587 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1589 - IBM RT and Stanford Enetfilter support has been added by
1590 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1591 both the vanilla Enetfilter interface, and the extended interface
1592 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1594 - TFTP packets are now printed (requests only).
1596 - BOOTP packets are now printed.
1598 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1600 - Sparc architectures, including the Sparcstation-1, are now
1601 supported thanks to Steve McCanne and Craig Leres.
1603 - SunOS 4 is now supported thanks to Micky Liu of Columbia

1606 - IP options are now printed.
1608 - RIP packets are now printed.
1610 - There's a -v flag that prints out more information than the
1611 default (e.g., it will enable printing of IP ttl, tos and id)
1612 and -q flag that prints out less (e.g., it will disable
1613 interpretation of AppleTalk-in-UDP).
1615 - The grammar has undergone substantial changes (if you have an
1616 earlier version of tcpdump, you should re-read the manual
1619 The most useful change is the addition of an expression
1620 syntax that lets you filter on arbitrary fields or values in the
1621 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1622 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1625 The most painful change is that concatenation no longer means
1626 "and" -- e.g., you have to say "host foo and port bar" instead
1627 of "host foo port bar". The up side to this down is that
1628 repeated qualifiers can be omitted, making most filter
1629 expressions shorter. E.g., you can now say "ip host foo and
1630 (bar or baz)" to look at ip traffic between hosts foo and bar or
1631 between hosts foo and baz. [The old way of saying this was "ip
1632 host foo and (ip host bar or ip host baz)".]
