1194 autoconf version is broken (it only puts the library name in the
1195 cache variable name). Thanks to John Hawkinson.
1197 - Add a local autoconf macro to check for types; the autoconf version
1198 is broken (it uses grep instead of actually compiling a code fragment).

1261 actually in the tcp header (in addition to the normal truncation
1262 checks). Fix the SACK code to print the N blocks (instead of the
1263 first block N times).
1265 - Don't say really small UDP packets are truncated just because they
1266 aren't big enough to be a RPC. As noted by David Sacerdote.
1268 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1270 - Added rfc1716 icmp codes as suggested by Martin Fredriksson

1304 printers. Thanks to John Hawkinson.

1368 - Add support for printing DVMRP and PIM traffic thanks to
1369 Havard Eidnes (Havard.Eidnes@runit.sintef.no).

1414 octet for the sa_family member. Thanks to Yoshitaka Tokugawa

1426 - Include time.h when SVR4 is defined to avoid problems under Solaris

1430 strings, not the local buffer. Thanks to Stefan Petri
1431 (petri@ibr.cs.tu-bs.de).
1433 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning
1434 that the selected value was not used. Thanks to Pascal Hennequin

1437 - Add a truncated packet test to print-nfs.c. Thanks to Pascal Hennequin.

1448 - Change configuration to not use gcc v2 flags with gcc v1.
1450 - Redo gmt2local() so that it works under BSDI (which seems to return
1451 an empty timezone struct from gettimeofday()). Based on report from
1452 Terry Kennedy (terry@spcvxa.spc.edu).
1454 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1455 on report from Mark Andrews (mandrews@alias.com).
1457 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1458 Orth (ro@techfak.uni-bielefeld.de).

1469 - Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
1471 v3.0 Mon Jun 20 19:23:27 PDT 1994
1473 - Added support for printing tcp option timestamps thanks to
1474 Mark Andrews (mandrews@alias.com).
1476 - Reorganize protocol dumpers to take const pointers to packets so they
1477 never change the contents (i.e., they used to do endian conversions
1478 in place). Previously, whenever more than one pass was taken over
1479 the packet, the packet contents would be dumped incorrectly (i.e.,
1480 the output form -x would be wrong on little endian machines because
1481 the protocol dumpers would modify the data). Thanks to Charles Hannum
1482 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1484 - Added support for decnet protocol dumping thanks to Jeff Mogul
1487 - Fix bug that caused length of packet to be incorrectly printed
1488 (off by ether header size) for unknown ethernet types thanks
1489 to Greg Miller (gmiller@kayak.mitre.org).
1491 - Added support for IPX protocol dumping thanks to Brad Parker
1494 - Added check to verify IP header checksum under -v thanks to
1495 Brad Parker (brad@fcr.com).
1497 - Move packet capture code to new libpcap library (which is
1498 packaged separately).
1500 - Prototype everything and assume an ansi compiler.
1502 - print-arp.c: Print hardware ethernet addresses if they're not
1505 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1506 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1508 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1511 - print-icmp.c: Byte swap netmask before printing. Thanks to
1512 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1514 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1515 By default, only the inner packet is dumped, appended with the token
1516 "(encap)". Under -v, both the inner and output packets are dumped
1517 (on the same line). Note that the filter applies to the original packet,
1518 not the encapsulated packet. So if you run tcpdump on a net with an
1519 IP Multicast tunnel, you cannot filter out the datagrams using the
1520 conventional syntax. (You can filter away all the ip-in-ip traffic
1521 with "not ip proto 4".)
1523 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1524 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1526 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1528 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1529 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1530 Add && and || operators
1532 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1534 - Fix bug with -c flag.
1536 v2.2 Fri May 22 17:19:41 PDT 1992
1538 - savefile.c: Remove hack that shouldn't have been exported. Add
1541 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1542 matches non-echo/reply ICMP packets.
1544 - Many improvements to filter code optimizer.
1546 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1547 so that protocol qualifications are allowed. For example, "ip broadcast"
1548 and "ether multicast" are valid filters.
1550 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1551 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1552 patches to netinet/if_loop.c.
1554 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1555 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1557 - Added EGP and OSPF printers, thanks to Jeffrey Honig.

1579 stanonik@nprdc.navy.mil) Add missing printf() argument.
1581 - print-bootp.c: First attempt at decoding the vendor buffer.
1583 - print-domain.c: Fix truncation checks.
1585 - print-icmp.c: Calculate length of packets from the ip header.
1587 - print-ip.c: Print frag id in decimal (so it's easier to match up
1588 with non-frags). Add support for ospf, egp and igmp.
1590 - print-nfs.c: Lots of changes.
1592 - print-ntp.c: Make some verbose output depend on -v.
1594 - print-snmp.c: New version from John LoVerso.
1596 - print-tcp.c: Print rfc1072 tcp options.
1598 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1599 (microseconds) worth of precision. Fix uid bugs.
1601 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1602 With this option, you can create an architecture independent binary
1603 trace file in real time, without the overhead of the packet printer.
1604 At a later time, the packets can be filtered (again) and printed.
1606 - BSD is supported. You must have BPF in your kernel.
1607 Since the filtering is now done in the kernel, fewer packets are
1608 dropped. In fact, with BPF and the packet dumper option, a measly
1609 Sun 3/50 can keep up with a busy network.
1611 - Compressed SLIP packets can now be dumped, provided you use our
1612 SLIP software and BPF. These packets are dumped as any other IP
1613 packet; the compressed headers are dumped with the '-e' option.
1615 - Machines with little-endian byte ordering are supported (thanks to
1618 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1620 - IBM RT and Stanford Enetfilter support has been added by
1621 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1622 both the vanilla Enetfilter interface, and the extended interface
1623 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1625 - TFTP packets are now printed (requests only).
1627 - BOOTP packets are now printed.
1629 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1631 - Sparc architectures, including the Sparcstation-1, are now
1632 supported thanks to Steve McCanne and Craig Leres.
1634 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1635 University (micky@cunixc.cc.columbia.edu).
1637 - IP options are now printed.
1639 - RIP packets are now printed.
1641 - There's a -v flag that prints out more information than the
1642 default (e.g., it will enable printing of IP ttl, tos and id)
1643 and -q flag that prints out less (e.g., it will disable
1644 interpretation of AppleTalk-in-UDP).
1646 - The grammar has undergone substantial changes (if you have an
1647 earlier version of tcpdump, you should re-read the manual
1650 The most useful change is the addition of an expression
1651 syntax that lets you filter on arbitrary fields or values in the
1652 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1653 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1656 The most painful change is that concatenation no longer means
1657 "and" -- e.g., you have to say "host foo and port bar" instead
1658 of "host foo port bar". The up side to this down is that
1659 repeated qualifiers can be omitted, making most filter
1660 expressions shorter. E.g., you can now say "ip host foo and
1661 (bar or baz)" to look at ip traffic between hosts foo and bar or
1662 between hosts foo and baz. [The old way of saying this was "ip
1663 host foo and (ip host bar or ip host baz)".]
