1222 - Add a local autoconf macro to check for types; the autoconf version
1223 is broken (it uses grep instead of actually compiling a code fragment).

1287 checks). Fix the SACK code to print the N blocks (instead of the
1288 first block N times).
1290 - Don't say really small UDP packets are truncated just because they
1291 aren't big enough to be a RPC. As noted by David Sacerdote.
1293 v3.2.1 Sun Jul 14 03:02:26 PDT 1996
1295 - Added rfc1716 icmp codes as suggested by Martin Fredriksson

1455 strings, not the local buffer. Thanks to Stefan Petri
1456 (petri@ibr.cs.tu-bs.de).
1458 - Detect when pcap raises the snaplen (e.g. with snit). Print a warning

1473 - Change configuration to not use gcc v2 flags with gcc v1.
1475 - Redo gmt2local() so that it works under BSDI (which seems to return
1476 an empty timezone struct from gettimeofday()). Based on report from
1477 Terry Kennedy (terry@spcvxa.spc.edu).
1479 - Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
1480 on report from Mark Andrews (mandrews@alias.com).
1482 - Don't pass cc flags to gcc. Resulted from a bug report from Rainer
1483 Orth (ro@techfak.uni-bielefeld.de).

1496 v3.0 Mon Jun 20 19:23:27 PDT 1994
1498 - Added support for printing tcp option timestamps thanks to
1499 Mark Andrews (mandrews@alias.com).
1501 - Reorganize protocol dumpers to take const pointers to packets so they
1502 never change the contents (i.e., they used to do endian conversions
1503 in place). Previously, whenever more than one pass was taken over
1504 the packet, the packet contents would be dumped incorrectly (i.e.,
1505 the output form -x would be wrong on little endian machines because
1506 the protocol dumpers would modify the data). Thanks to Charles Hannum
1507 (mycroft@gnu.ai.mit.edu) for reporting this problem.
1509 - Added support for decnet protocol dumping thanks to Jeff Mogul
1512 - Fix bug that caused length of packet to be incorrectly printed
1513 (off by ether header size) for unknown ethernet types thanks
1514 to Greg Miller (gmiller@kayak.mitre.org).
1516 - Added support for IPX protocol dumping thanks to Brad Parker
1519 - Added check to verify IP header checksum under -v thanks to
1520 Brad Parker (brad@fcr.com).
1522 - Move packet capture code to new libpcap library (which is
1523 packaged separately).
1525 - Prototype everything and assume an ansi compiler.
1527 - print-arp.c: Print hardware ethernet addresses if they're not
1530 - print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
1531 Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
1533 - print-fddi.c: Improvements. Thanks to Jeffrey Mogul
1536 - print-icmp.c: Byte swap netmask before printing. Thanks to
1537 Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
1539 - print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
1540 By default, only the inner packet is dumped, appended with the token
1541 "(encap)". Under -v, both the inner and output packets are dumped
1542 (on the same line). Note that the filter applies to the original packet,
1543 not the encapsulated packet. So if you run tcpdump on a net with an
1544 IP Multicast tunnel, you cannot filter out the datagrams using the
1545 conventional syntax. (You can filter away all the ip-in-ip traffic
1546 with "not ip proto 4".)
1548 - print-nfs.c: Keep pending rpc's in circular table. Add generic
1549 nfs header and remove os dependences. Thanks to Jeffrey Mogul.
1551 - print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
1553 - tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
1554 (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
1555 Add && and || operators
1557 v2.2.1 Tue Jun 6 17:57:22 PDT 1992
1559 - Fix bug with -c flag.
1561 v2.2 Fri May 22 17:19:41 PDT 1992
1563 - savefile.c: Remove hack that shouldn't have been exported. Add
1566 - Added the 'icmp' keyword. For example, 'icmp[0] != 8 and icmp[0] != 0'
1567 matches non-echo/reply ICMP packets.
1569 - Many improvements to filter code optimizer.
1571 - Added 'multicast' keyword and extended the 'broadcast' keyword can now be
1572 so that protocol qualifications are allowed. For example, "ip broadcast"
1573 and "ether multicast" are valid filters.
1575 - Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
1576 Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
1577 patches to netinet/if_loop.c.
1579 - Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
1580 Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
1582 - Added EGP and OSPF printers, thanks to Jeffrey Honig.
1584 v2.1 Tue Jan 28 11:00:14 PST 1992
1586 - Internal release (never publicly exported).
1588 v2.0.1 Sun Jan 26 21:10:10 PDT
1590 - Various byte ordering fixes.
1592 - Add truncation checks.
1594 - inet.c: Support BSD style SIOCGIFCONF.
1596 - nametoaddr.c: Handle multi addresses for single host.
1598 - optimize.c: Rewritten.
1600 - pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
1603 - print-atal.c: Fix an alignment bug (thanks to
1604 stanonik@nprdc.navy.mil) Add missing printf() argument.
1606 - print-bootp.c: First attempt at decoding the vendor buffer.
1608 - print-domain.c: Fix truncation checks.
1610 - print-icmp.c: Calculate length of packets from the ip header.
1612 - print-ip.c: Print frag id in decimal (so it's easier to match up
1613 with non-frags). Add support for ospf, egp and igmp.
1615 - print-nfs.c: Lots of changes.
1617 - print-ntp.c: Make some verbose output depend on -v.
1619 - print-snmp.c: New version from John LoVerso.
1621 - print-tcp.c: Print rfc1072 tcp options.
1623 - tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
1624 (microseconds) worth of precision. Fix uid bugs.
1626 - A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
1627 With this option, you can create an architecture independent binary
1628 trace file in real time, without the overhead of the packet printer.
1629 At a later time, the packets can be filtered (again) and printed.
1631 - BSD is supported. You must have BPF in your kernel.
1632 Since the filtering is now done in the kernel, fewer packets are
1633 dropped. In fact, with BPF and the packet dumper option, a measly
1634 Sun 3/50 can keep up with a busy network.
1636 - Compressed SLIP packets can now be dumped, provided you use our
1637 SLIP software and BPF. These packets are dumped as any other IP
1638 packet; the compressed headers are dumped with the '-e' option.
1640 - Machines with little-endian byte ordering are supported (thanks to
1643 - Ultrix 4.0 is supported (also thanks to Jeff Mogul).
1645 - IBM RT and Stanford Enetfilter support has been added by
1646 Rayan Zachariassen <rayan@canet.ca>. Tcpdump has been tested under
1647 both the vanilla Enetfilter interface, and the extended interface
1648 (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
1650 - TFTP packets are now printed (requests only).
1652 - BOOTP packets are now printed.
1654 - SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
1656 - Sparc architectures, including the Sparcstation-1, are now
1657 supported thanks to Steve McCanne and Craig Leres.
1659 - SunOS 4 is now supported thanks to Micky Liu of Columbia
1660 University (micky@cunixc.cc.columbia.edu).
1662 - IP options are now printed.
1664 - RIP packets are now printed.
1666 - There's a -v flag that prints out more information than the
1667 default (e.g., it will enable printing of IP ttl, tos and id)
1668 and -q flag that prints out less (e.g., it will disable
1669 interpretation of AppleTalk-in-UDP).
1671 - The grammar has undergone substantial changes (if you have an
1672 earlier version of tcpdump, you should re-read the manual
1675 The most useful change is the addition of an expression
1676 syntax that lets you filter on arbitrary fields or values in the
1677 packet. E.g., "ip[0] > 0x45" would print only packets with IP
1678 options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
1681 The most painful change is that concatenation no longer means
1682 "and" -- e.g., you have to say "host foo and port bar" instead
1683 of "host foo port bar". The up side to this down is that
1684 repeated qualifiers can be omitted, making most filter
1685 expressions shorter. E.g., you can now say "ip host foo and
1686 (bar or baz)" to look at ip traffic between hosts foo and bar or
1687 between hosts foo and baz. [The old way of saying this was "ip
1688 host foo and (ip host bar or ip host baz)".]
