1191 autoconf version is broken (it only puts the library name in the
1192 cache variable name). Thanks to John Hawkinson.
1194 - Add a local autoconf macro to check for types; the autoconf version
1195 is broken (it uses grep instead of actually compiling a code fragment).

1258 actually in the tcp header (in addition to the normal truncation
1259 checks). Fix the SACK code to print the N blocks (instead of the
1260 first block N times).
1262 - Don't say really small UDP packets are truncated just because they
1263 aren't big enough to be a RPC. As noted by David Sacerdote.
1265 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1267 - Added rfc1716 icmp codes as suggested by Martin Fredriksson

1276 - Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
1277 (kushida@trl.ibm.co.jp)
1279 - Check igmp checksum if possible. Thanks to John Hawkinson.

1287 - Avoid infinite loop in tcp options printing code. Thanks to Jeffrey

1301 printers. Thanks to John Hawkinson.

1423 - Include time.h when SVR4 is defined to avoid problems under Solaris

1427 strings, not the local buffer. Thanks to Stefan Petri
1428 (petri@ibr.cs.tu-bs.de).
1430 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning

1434 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.

1445 - Change configuration to not use gcc v2 flags with gcc v1.
1447 - Redo gmt2local() so that it works under BSDI (which seems to return
1448 an empty timezone struct from gettimeofday()). Based on report from
1449 Terry Kennedy (terry@spcvxa.spc.edu).
1451 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1452 on report from Mark Andrews (mandrews@alias.com).
1454 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1455 Orth (ro@techfak.uni-bielefeld.de).

1466 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1468 v3.0 Mon Jun 20 19:23:27 PDT 1994
1470 - Added support for printing tcp option timestamps thanks to
1471 Mark Andrews (mandrews@alias.com).
1473 - Reorganize protocol dumpers to take const pointers to packets so they
1474 never change the contents (i.e., they used to do endian conversions
1475 in place). Previously, whenever more than one pass was taken over
1476 the packet, the packet contents would be dumped incorrectly (i.e.,
1477 the output form -x would be wrong on little endian machines because
1478 the protocol dumpers would modify the data). Thanks to Charles Hannum
1479 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1481 - Added support for decnet protocol dumping thanks to Jeff Mogul
1484 - Fix bug that caused length of packet to be incorrectly printed
1485 (off by ether header size) for unknown ethernet types thanks
1486 to Greg Miller (gmiller@kayak.mitre.org).
1488 - Added support for IPX protocol dumping thanks to Brad Parker
1491 - Added check to verify IP header checksum under -v thanks to
1492 Brad Parker (brad@fcr.com).
1494 - Move packet capture code to new libpcap library (which is
1495 packaged separately).
1497 - Prototype everything and assume an ansi compiler.
1499 - print-arp.c: Print hardware ethernet addresses if they're not
1502 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1503 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1505 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1508 - print-icmp.c: Byte swap netmask before printing. Thanks to
1509 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1511 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1512 By default, only the inner packet is dumped, appended with the token
1513 "(encap)". Under -v, both the inner and output packets are dumped
1514 (on the same line). Note that the filter applies to the original packet,
1515 not the encapsulated packet. So if you run tcpdump on a net with an
1516 IP Multicast tunnel, you cannot filter out the datagrams using the
1517 conventional syntax. (You can filter away all the ip-in-ip traffic
1518 with "not ip proto 4".)
1520 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1521 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1523 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1525 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1526 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1527 Add && and || operators
1529 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1531 - Fix bug with -c flag.
1533 v2.2 Fri May 22 17:19:41 PDT 1992
1535 - savefile.c: Remove hack that shouldn't have been exported. Add
1538 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1539 matches non-echo/reply ICMP packets.
1541 - Many improvements to filter code optimizer.
1543 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1544 so that protocol qualifications are allowed. For example, "ip broadcast"
1545 and "ether multicast" are valid filters.
1547 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1548 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1549 patches to netinet/if_loop.c.
1551 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1552 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1554 - Added EGP and OSPF printers, thanks to Jeffrey Honig.

1576 stanonik@nprdc.navy.mil) Add missing printf() argument.
1578 - print-bootp.c: First attempt at decoding the vendor buffer.
1580 - print-domain.c: Fix truncation checks.
1582 - print-icmp.c: Calculate length of packets from the ip header.
1584 - print-ip.c: Print frag id in decimal (so it's easier to match up
1585 with non-frags). Add support for ospf, egp and igmp.
1587 - print-nfs.c: Lots of changes.
1589 - print-ntp.c: Make some verbose output depend on -v.
1591 - print-snmp.c: New version from John LoVerso.
1593 - print-tcp.c: Print rfc1072 tcp options.
1595 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1596 (microseconds) worth of precision. Fix uid bugs.
1598 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1599 With this option, you can create an architecture independent binary
1600 trace file in real time, without the overhead of the packet printer.
1601 At a later time, the packets can be filtered (again) and printed.
1603 - BSD is supported. You must have BPF in your kernel.
1604 Since the filtering is now done in the kernel, fewer packets are
1605 dropped. In fact, with BPF and the packet dumper option, a measly
1606 Sun 3/50 can keep up with a busy network.
1608 - Compressed SLIP packets can now be dumped, provided you use our
1609 SLIP software and BPF. These packets are dumped as any other IP
1610 packet; the compressed headers are dumped with the '-e' option.
1612 - Machines with little-endian byte ordering are supported (thanks to
1615 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1617 - IBM RT and Stanford Enetfilter support has been added by
1618 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1619 both the vanilla Enetfilter interface, and the extended interface
1620 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1622 - TFTP packets are now printed (requests only).
1624 - BOOTP packets are now printed.
1626 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1628 - Sparc architectures, including the Sparcstation-1, are now
1629 supported thanks to Steve McCanne and Craig Leres.
1631 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1632 University (micky@cunixc.cc.columbia.edu).
1634 - IP options are now printed.
1636 - RIP packets are now printed.
1638 - There's a -v flag that prints out more information than the
1639 default (e.g., it will enable printing of IP ttl, tos and id)
1640 and -q flag that prints out less (e.g., it will disable
1641 interpretation of AppleTalk-in-UDP).
1643 - The grammar has undergone substantial changes (if you have an
1644 earlier version of tcpdump, you should re-read the manual
1647 The most useful change is the addition of an expression
1648 syntax that lets you filter on arbitrary fields or values in the
1649 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1650 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1653 The most painful change is that concatenation no longer means
1654 "and" -- e.g., you have to say "host foo and port bar" instead
1655 of "host foo port bar". The up side to this down is that
1656 repeated qualifiers can be omitted, making most filter
1657 expressions shorter. E.g., you can now say "ip host foo and
1658 (bar or baz)" to look at ip traffic between hosts foo and bar or
1659 between hosts foo and baz. [The old way of saying this was "ip
1660 host foo and (ip host bar or ip host baz)".]
