1165 autoconf version is broken (it only puts the library name in the
1166 cache variable name). Thanks to John Hawkinson.
1168 - Add a local autoconf macro to check for types; the autoconf version
1169 is broken (it uses grep instead of actually compiling a code fragment).

1231 (davids@secnet.com). Also, check tcp options to make sure they ar
1232 actually in the tcp header (in addition to the normal truncation
1233 checks). Fix the SACK code to print the N blocks (instead of the
1234 first block N times).
1236 - Don't say really small UDP packets are truncated just because they
1237 aren't big enough to be a RPC. As noted by David Sacerdote.
1239 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1241 - Added rfc1716 icmp codes as suggested by Martin Fredriksson
1244 - Print mtu for icmp unreach need frag packets. Thanks to John
1245 Hawkinson (jhawk@mit.edu)
1247 - Decode icmp router discovery messages. Thanks to Jeffrey Honig
1250 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1251 (kushida@trl.ibm.co.jp)
1253 - Check igmp checksum if possible. Thanks to John Hawkinson.
1255 - Made changes for SINIX. Thanks to Andrej Borsenkow

1385 octet for the sa_family member. Thanks to Yoshitaka Tokugawa
1388 - Don't checksum ip header if we don't have all of it. Thanks to John
1389 Hawkinson (jhawk@mit.edu).

1401 strings, not the local buffer. Thanks to Stefan Petri
1402 (petri@ibr.cs.tu-bs.de).
1404 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1405 that the selected value was not used. Thanks to Pascal Hennequin
1406 (Pascal.Hennequin@hugo.int-evry.fr).
1408 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.
1410 - BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
1412 v3.0.3 Sun Oct 1 18:35:00 GMT 1995
1414 - Although there never was a 3.0.3 release, the linux boys cleverly
1415 "released" one in late 1995.
1417 v3.0.2 Thu Apr 20 21:28:16 PDT 1995
1419 - Change configuration to not use gcc v2 flags with gcc v1.
1421 - Redo gmt2local() so that it works under BSDI (which seems to return
1422 an empty timezone struct from gettimeofday()). Based on report from
1423 Terry Kennedy (terry@spcvxa.spc.edu).
1425 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1426 on report from Mark Andrews (mandrews@alias.com).
1428 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1429 Orth (ro@techfak.uni-bielefeld.de).
1431 - Fixed printout of connection id for uncompressed tcp slip packets.
1432 Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
1434 - Hack around deficiency in Ultrix's make.

1438 v3.0.1 Wed Aug 31 22:42:26 PDT 1994
1440 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1442 v3.0 Mon Jun 20 19:23:27 PDT 1994
1444 - Added support for printing tcp option timestamps thanks to
1445 Mark Andrews (mandrews@alias.com).
1447 - Reorganize protocol dumpers to take const pointers to packets so they
1448 never change the contents (i.e., they used to do endian conversions
1449 in place). Previously, whenever more than one pass was taken over
1450 the packet, the packet contents would be dumped incorrectly (i.e.,
1451 the output form -x would be wrong on little endian machines because
1452 the protocol dumpers would modify the data). Thanks to Charles Hannum
1453 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1455 - Added support for decnet protocol dumping thanks to Jeff Mogul
1458 - Fix bug that caused length of packet to be incorrectly printed
1459 (off by ether header size) for unknown ethernet types thanks
1460 to Greg Miller (gmiller@kayak.mitre.org).
1462 - Added support for IPX protocol dumping thanks to Brad Parker
1465 - Added check to verify IP header checksum under -v thanks to
1466 Brad Parker (brad@fcr.com).
1468 - Move packet capture code to new libpcap library (which is
1469 packaged separately).
1471 - Prototype everything and assume an ansi compiler.
1473 - print-arp.c: Print hardware ethernet addresses if they're not
1476 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1477 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1479 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1482 - print-icmp.c: Byte swap netmask before printing. Thanks to
1483 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1485 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1486 By default, only the inner packet is dumped, appended with the token
1487 "(encap)". Under -v, both the inner and output packets are dumped
1488 (on the same line). Note that the filter applies to the original packet,
1489 not the encapsulated packet. So if you run tcpdump on a net with an
1490 IP Multicast tunnel, you cannot filter out the datagrams using the
1491 conventional syntax. (You can filter away all the ip-in-ip traffic
1492 with "not ip proto 4".)
1494 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1495 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1497 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1499 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1500 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1501 Add && and || operators
1503 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1505 - Fix bug with -c flag.
1507 v2.2 Fri May 22 17:19:41 PDT 1992
1509 - savefile.c: Remove hack that shouldn't have been exported. Add
1512 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1513 matches non-echo/reply ICMP packets.
1515 - Many improvements to filter code optimizer.
1517 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1518 so that protocol qualifications are allowed. For example, "ip broadcast"
1519 and "ether multicast" are valid filters.
1521 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1522 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1523 patches to netinet/if_loop.c.
1525 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1526 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1528 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1530 v2.1 Tue Jan 28 11:00:14 PST 1992
1532 - Internal release (never publicly exported).
1534 v2.0.1 Sun Jan 26 21:10:10 PDT
1536 - Various byte ordering fixes.
1538 - Add truncation checks.
1540 - inet.c: Support BSD style SIOCGIFCONF.
1542 - nametoaddr.c: Handle multi addresses for single host.
1544 - optimize.c: Rewritten.
1546 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1549 - print-atal.c: Fix an alignment bug (thanks to
1550 stanonik@nprdc.navy.mil) Add missing printf() argument.
1552 - print-bootp.c: First attempt at decoding the vendor buffer.
1554 - print-domain.c: Fix truncation checks.
1556 - print-icmp.c: Calculate length of packets from the ip header.
1558 - print-ip.c: Print frag id in decimal (so it's easier to match up
1559 with non-frags). Add support for ospf, egp and igmp.
1561 - print-nfs.c: Lots of changes.
1563 - print-ntp.c: Make some verbose output depend on -v.
1565 - print-snmp.c: New version from John LoVerso.
1567 - print-tcp.c: Print rfc1072 tcp options.
1569 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1570 (microseconds) worth of precision. Fix uid bugs.
1572 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1573 With this option, you can create an architecture independent binary
1574 trace file in real time, without the overhead of the packet printer.
1575 At a later time, the packets can be filtered (again) and printed.
1577 - BSD is supported. You must have BPF in your kernel.
1578 Since the filtering is now done in the kernel, fewer packets are
1579 dropped. In fact, with BPF and the packet dumper option, a measly
1580 Sun 3/50 can keep up with a busy network.
1582 - Compressed SLIP packets can now be dumped, provided you use our
1583 SLIP software and BPF. These packets are dumped as any other IP
1584 packet; the compressed headers are dumped with the '-e' option.
1586 - Machines with little-endian byte ordering are supported (thanks to
1589 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1591 - IBM RT and Stanford Enetfilter support has been added by
1592 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1593 both the vanilla Enetfilter interface, and the extended interface
1594 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1596 - TFTP packets are now printed (requests only).
1598 - BOOTP packets are now printed.
1600 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1602 - Sparc architectures, including the Sparcstation-1, are now
1603 supported thanks to Steve McCanne and Craig Leres.
1605 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1606 University (micky@cunixc.cc.columbia.edu).
1608 - IP options are now printed.
1610 - RIP packets are now printed.
1612 - There's a -v flag that prints out more information than the
1613 default (e.g., it will enable printing of IP ttl, tos and id)
1614 and -q flag that prints out less (e.g., it will disable
1615 interpretation of AppleTalk-in-UDP).
1617 - The grammar has undergone substantial changes (if you have an
1618 earlier version of tcpdump, you should re-read the manual
1621 The most useful change is the addition of an expression
1622 syntax that lets you filter on arbitrary fields or values in the
1623 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1624 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1627 The most painful change is that concatenation no longer means
1628 "and" -- e.g., you have to say "host foo and port bar" instead
1629 of "host foo port bar". The up side to this down is that
1630 repeated qualifiers can be omitted, making most filter
1631 expressions shorter. E.g., you can now say "ip host foo and
1632 (bar or baz)" to look at ip traffic between hosts foo and bar or
1633 between hosts foo and baz. [The old way of saying this was "ip
1634 host foo and (ip host bar or ip host baz)".]
