+
+v3.4 Sat Jul 25 12:40:55 PDT 1998
+
+- Hardwire Linux slip support since it's too hard to detect.
+
+- Redo configuration of "network" libraries (-lsocket and -lnsl) to
+  deal with IRIX. Thanks to John Hawkinson (jhawk@mit.edu)
+
+- Added -a which tries to translate network and broadcast addresses to
+  names. Suggested by Rob van Nieuwkerk (robn@verdi.et.tudelft.nl)
+
+- Added a configure option to disable gcc.
+
+- Added a "raw" packet printer.
+
+- Not having an interface address is no longer fatal. Requested by John
+  Hawkinson.
+
+- Rework signal setup to accommodate Linux.
+
+- OSPF truncation check fix. Also display the type of OSPF packets
+  using MD5 authentication. Thanks to Brian Wellington
+  (bwelling@tis.com)
+
+- Fix truncation check bugs in the Kerberos printer. Reported by Ezra
+  Peisach (epeisach@mit.edu)
+
+- Don't catch SIGHUP when invoked with nohup(1). Thanks to Dave Plonka
+  (plonka@mfa.com)
+
+- Specify full install target as a way of detecting if install
+  directory does not exist. Thanks to Dave Plonka.
+
+- Bit-swap FDDI addresses for BSD/OS too. Thanks to Paul Vixie
+  (paul@vix.com)
+
+- Fix off-by-one bug when testing size of ethernet packets. Thanks to
+  Marty Leisner (leisner@sdsp.mc.xerox.com)
+
+- Add a local autoconf macro to check for routines in libraries; the
+  autoconf version is broken (it only puts the library name in the
+  cache variable name). Thanks to John Hawkinson.
+
+- Add a local autoconf macro to check for types; the autoconf version
+  is broken (it uses grep instead of actually compiling a code fragment).
+
+- Modified to support the new BSD/OS 2.1 PPP and SLIP link layer header
+  formats.
+
+- Extend OSF ip header workaround to versions 1 and 2.
+
+- Fix some signed problems in the nfs printer. As reported by David
+  Sacerdote (davids@silence.secnet.com)
+
+- Detect group wheel and use it as the default since BSD/OS' install
+  can't hack numeric groups. Reported by David Sacerdote.
+
+- AIX needs special loader options. Thanks to Jonathan I. Kamens
+  (jik@cam.ov.com)
+
+- Fixed the nfs printer to print port numbers in decimal. Thanks to
+  Kent Vander Velden (graphix@iastate.edu)
+
+- Find installed libpcap in /usr/local/lib when not using gcc.
+
+- Disallow network masks with non-network bits set.
+
+- Attempt to detect "egcs" versions of gcc.
+
+- Add missing closing double quotes when displaying bootp strings.
+  Reported by Viet-Trung Luu (vluu@picard.math.uwaterloo.ca)
+
+v3.3 Sat Nov 30 20:56:27 PST 1996
+
+- Added Linux support.
+
+- GRE encapsulated packet printer thanks to John Hawkinson
+  (jhawk@mit.edu)
+
+- Rewrite gmt2local() to avoid problematic os dependencies.
+
+- Suppress nfs truncation message on errors.
+
+- Add missing m4 quoting in AC_LBL_UNALIGNED_ACCESS autoconf macro.
+  Reported by Joachim Ott (ott@ardala.han.de)
+
+- Enable "ip_hl vs. ip_vhl" workaround for OSF4 too.
+
+- Print arp hardware type in host order. Thanks to Onno van der Linden
+  (onno@simplex.nl)
+
+- Avoid solaris compiler warnings. Thanks to Bruce Barnett
+  (barnett@grymoire.crd.ge.com)
+
+- Fix rip printer to not print one more route than is actually in the
+  packet. Thanks to Jean-Luc Richier (Jean-Luc.Richier@imag.fr) and
+  Bill Fenner (fenner@parc.xerox.com)
+
+- Use autoconf endian detection since BYTE_ORDER isn't defined on all systems.
+
+- Fix dvmrp printer truncation checks and add a dvmrp probe printer.
+  Thanks to Danny J. Mitzel (mitzel@ipsilon.com)
+
+- Rewrite ospf printer to improve truncation checks.
+
+- Don't parse tcp options past the EOL. As noted by David Sacerdote
+  (davids@secnet.com). Also, check tcp options to make sure they ar
+  actually in the tcp header (in addition to the normal truncation
+  checks). Fix the SACK code to print the N blocks (instead of the
+  first block N times).
+
+- Don't say really small UDP packets are truncated just because they
+  aren't big enough to be a RPC. As noted by David Sacerdote.
+
+v3.2.1 Sun Jul 14 03:02:26 PDT 1996
+
+- Added rfc1716 icmp codes as suggested by Martin Fredriksson
+  (martin@msp.se)

+  Hawkinson (jhawk@mit.edu)
+
+- Decode icmp router discovery messages. Thanks to Jeffrey Honig
+  (jch@bsdi.com)
+
+- Added a printer entry for DLT_IEEE802 as suggested by Tak Kushida
+  (kushida@trl.ibm.co.jp)
+
+- Check igmp checksum if possible. Thanks to John Hawkinson.
+
+- Made changes for SINIX. Thanks to Andrej Borsenkow
+  (borsenkow.msk@sni.de)
+

+  Thanks to John Hawkinson.
+
+- Avoid infinite loop in tcp options printing code. Thanks to Jeffrey
+  Mogul (mogul@pa.dec.com)
+
+- Avoid using -lsocket in IRIX 5.2 and earlier since it breaks snoop.
+  Thanks to John Hawkinson.
+
+- Added some more packet truncation checks.
+
+- On systems that have it, use sigset() instead of signal() since
+  signal() has different semantics on these systems.
+
+- Fixed some more alignment problems on the alpha.
+
+- Add code to massage unprintable characters in the domain and ipx
+  printers. Thanks to John Hawkinson.
+
+- Added explicit netmask support. Thanks to Steve Nuchia
+  (steve@research.oknet.com)
+
+- Add "sca" keyword (for DEC cluster services) as suggested by Terry
+  Kennedy (terry@spcvxa.spc.edu)
+
+- Add "atalk" keyword as suggested by John Hawkinson.
+
+- Added an igrp printer. Thanks to Francis Dupont

+  Pavlin Ivanov Radoslavov (pavlin@cs.titech.ac.jp)
+
+v3.2 Sun Jun 23 02:28:10 PDT 1996
+
+- Print new icmp unreachable codes as suggested by Martin Fredriksson
+  (martin@msp.se). Also print code value when unknown for icmp redirect
+  and time exceeded.
+
+- Fix an alignment endian bug in getname(). Thanks to John Hawkinson.
+
+- Define "new" domain record types if not found in arpa/nameserv.h.
+  Resulted from a suggestion from John Hawkinson (jhawk@mit.edu). Also
+  fixed an endian bug when printing mx record and added some new record
+  types.
+
+- Added RIP V2 support. Thanks to Jeffrey Honig (jch@bsdi.com)
+
+- Added T/TCP options printing. As suggested by Richard Stevens
+  (rstevens@noao.edu)
+
+- Use autoconf to detect architectures that can't handle misaligned
+  accesses.
+
+v3.1 Thu Jun 13 20:59:32 PDT 1996
+
+- Changed u_int32/int32 to u_int32_t/int32_t to be consistent with bsd
+  and bind (as suggested by Charles Hannum).
+
+- Port to GNU autoconf.
+
+- Add support for printing DVMRP and PIM traffic thanks to
+  Havard Eidnes (Havard.Eidnes@runit.sintef.no).

+- Check return status from malloc/calloc/etc.
+
+- Check return status from pcap_loop() so we can print an error and
+  exit with a bad status if there were problems.
+
+- Bail if ip option length is <= 0. Resulted from a bug report from
+  Darren Reed (darrenr@vitruvius.arbld.unimelb.edu.au).
+
+- Print out a little more information for sun rpc packets.
+
+- Add suport for Kerberos 4 thanks to John Hawkinson (jhawk@mit.edu).
+
+- Fixed the Fix EXTRACT_SHORT() and EXTRACT_LONG() macros (which were
+  wrong on little endian machines).
+
+- Fixed alignment bug in ipx_decode(). Thanks to Matt Crawford
+  (crawdad@fnal.gov).
+
+- Fix ntp_print() to not print garbage when the stratum is
+  "unspecified." Thanks to Deus Ex Machina (root@belle.bork.com).
+
+- Rewrote tcp options printer code to check for truncation. Added
+  selective acknowledgment case.
+
+- Fixed an endian bug in the ospf printer. Thanks to Jeffrey C Honig
+  (jch@bsdi.com)
+
+- Fix rip printer to handle 4.4 BSD sockaddr struct which only uses one
+  octet for the sa_family member. Thanks to Yoshitaka Tokugawa
+  (toku@dit.co.jp)
+
+- Don't checksum ip header if we don't have all of it. Thanks to John
+  Hawkinson (jhawk@mit.edu).
+ 
+- Print out hostnames if possible in egp printer. Thanks to Jeffrey

+
+- BYTEORDER -> BYTE_ORDER Thanks to Terry Kennedy (terry@spcvxa.spc.edu).
+
+v3.0.3 Sun Oct  1 18:35:00 GMT 1995
+
+- Although there never was a 3.0.3 release, the linux boys cleverly
+  "released" one in late 1995.
+
+v3.0.2 Thu Apr 20 21:28:16 PDT 1995
+
+- Change configuration to not use gcc v2 flags with gcc v1.
+
+- Redo gmt2local() so that it works under BSDI (which seems to return
+  an empty timezone struct from gettimeofday()). Based on report from
+  Terry Kennedy (terry@spcvxa.spc.edu).
+
+- Change configure to recognize IP[0-9]* as "mips" SGI hardware. Based
+  on report from Mark Andrews (mandrews@alias.com).
+
+- Don't pass cc flags to gcc. Resulted from a bug report from Rainer
+  Orth (ro@techfak.uni-bielefeld.de).
+
+- Fixed printout of connection id for uncompressed tcp slip packets.
+  Resulted from a bug report from Richard Stevens (rstevens@noao.edu).
+
+- Hack around deficiency in Ultrix's make.
+
+- Add ETHERTYPE_TRAIL define which is missing from irix5.
+
+v3.0.1 Wed Aug 31 22:42:26 PDT 1994
+
+- Fix problems with gcc2 vs. malloc() and read() prototypes under SunOS 4.
+
+v3.0 Mon Jun 20 19:23:27 PDT 1994
+
+- Added support for printing tcp option timestamps thanks to
+  Mark Andrews (mandrews@alias.com).
+
+- Reorganize protocol dumpers to take const pointers to packets so they
+  never change the contents (i.e., they used to do endian conversions
+  in place).  Previously, whenever more than one pass was taken over
+  the packet, the packet contents would be dumped incorrectly (i.e.,
+  the output form -x would be wrong on little endian machines because
+  the protocol dumpers would modify the data).  Thanks to Charles Hannum
+  (mycroft@gnu.ai.mit.edu) for reporting this problem.
+
+- Added support for decnet protocol dumping thanks to Jeff Mogul
+  (mogul@pa.dec.com).
+
+- Fix bug that caused length of packet to be incorrectly printed
+  (off by ether header size) for unknown ethernet types thanks
+  to Greg Miller (gmiller@kayak.mitre.org).
+
+- Added support for IPX protocol dumping thanks to Brad Parker
+  (brad@fcr.com).
+
+- Added check to verify IP header checksum under -v thanks to
+  Brad Parker (brad@fcr.com).
+
+- Move packet capture code to new libpcap library (which is
+  packaged separately).
+
+- Prototype everything and assume an ansi compiler.
+
+- print-arp.c: Print hardware ethernet addresses if they're not
+  what we expect.
+
+- print-bootp.c: Decode the cmu vendor field. Add RFC1497 tags.
+  Many helpful suggestions from Gordon Ross (gwr@jericho.mc.com).
+
+- print-fddi.c: Improvements. Thanks to Jeffrey Mogul
+  (mogul@pa.dec.com).
+
+- print-icmp.c: Byte swap netmask before printing. Thanks to
+  Richard Stevens (rstevens@noao.edu). Print icmp type when unknown.
+
+- print-ip.c: Print the inner ip datagram of ip-in-ip encapsulated packets.
+  By default, only the inner packet is dumped, appended with the token
+  "(encap)".  Under -v, both the inner and output packets are dumped
+  (on the same line).  Note that the filter applies to the original packet,
+  not the encapsulated packet.  So if you run tcpdump on a net with an
+  IP Multicast tunnel, you cannot filter out the datagrams using the
+  conventional syntax.  (You can filter away all the ip-in-ip traffic
+  with "not ip proto 4".)
+
+- print-nfs.c: Keep pending rpc's in circular table. Add generic
+  nfs header and remove os dependences. Thanks to Jeffrey Mogul.
+
+- print-ospf.c: Improvements. Thanks to Jeffrey Mogul.
+
+- tcpdump.c: Add -T flag allows interpretation of "vat", "wb", "rpc"
+  (sunrpc) and rtp packets. Added "inbound" and "outbound" keywords
+  Add && and || operators
+
+v2.2.1 Tue Jun 6 17:57:22 PDT 1992
+
+- Fix bug with -c flag.
+
+v2.2 Fri May 22 17:19:41 PDT 1992
+
+- savefile.c: Remove hack that shouldn't have been exported. Add
+  truncate checks.
+
+- Added the 'icmp' keyword.  For example, 'icmp[0] != 8 and icmp[0] != 0'
+  matches non-echo/reply ICMP packets.
+
+- Many improvements to filter code optimizer.
+
+- Added 'multicast' keyword and extended the 'broadcast' keyword can now be
+  so that protocol qualifications are allowed. For example, "ip broadcast"
+  and "ether multicast" are valid filters.
+
+- Added support for monitoring the loopback interface (i.e. 'tcpdump -i lo').
+  Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) contributed the kernel
+  patches to netinet/if_loop.c.
+
+- Added support for the Ungermann-Bass Ethernet on IBM/PC-RTs running AOS.
+  Contact Jeffrey Honig (jch@MITCHELL.CIT.CORNELL.EDU) for the diffs.
+
+- Added EGP and OSPF printers, thanks to Jeffrey Honig.
+
+v2.1 Tue Jan 28 11:00:14 PST 1992
+
+- Internal release (never publically exported).
+
+v2.0.1 Sun Jan 26 21:10:10 PDT
+
+- Various byte ordering fixes.
+
+- Add truncation checks.
+
+- inet.c: Support BSD style SIOCGIFCONF.
+
+- nametoaddr.c: Handle multi addresses for single host.
+
+- optimize.c: Rewritten.
+
+- pcap-bpf.c: don't choke when we get ptraced. only set promiscuous
+  for broadcast nets.
+
+- print-atal.c: Fix an alignment bug (thanks to
+  stanonik@nprdc.navy.mil) Add missing printf() argument.
+
+- print-bootp.c: First attempt at decoding the vendor buffer.
+
+- print-domain.c: Fix truncation checks.
+
+- print-icmp.c: Calculate length of packets from the ip header.
+
+- print-ip.c: Print frag id in decimal (so it's easier to match up
+  with non-frags). Add support for ospf, egp and igmp.
+
+- print-nfs.c: Lots of changes.
+
+- print-ntp.c: Make some verbose output depend on -v.
+
+- print-snmp.c: New version from John LoVerso.
+
+- print-tcp.c: Print rfc1072 tcp options.
+
+- tcpdump.c: Print "0x" prefix for %x formats. Always print 6 digits
+  (microseconds) worth of precision. Fix uid bugs.
+
+- A packet dumper has been added (thanks to Jeff Mogul of DECWRL).
+  With this option, you can create an architecture independent binary
+  trace file in real time, without the overhead of the packet printer.
+  At a later time, the packets can be filtered (again) and printed.
+
+- BSD is supported.  You must have BPF in your kernel.
+  Since the filtering is now done in the kernel, fewer packets are
+  dropped.  In fact, with BPF and the packet dumper option, a measly
+  Sun 3/50 can keep up with a busy network.
+
+- Compressed SLIP packets can now be dumped, provided you use our
+  SLIP software and BPF.  These packets are dumped as any other IP
+  packet; the compressed headers are dumped with the '-e' option.
+
+- Machines with little-endian byte ordering are supported (thanks to
+  Jeff Mogul).
+
+- Ultrix 4.0 is supported (also thanks to Jeff Mogul).
+
+- IBM RT and Stanford Enetfilter support has been added by
+  Rayan Zachariassen <rayan@canet.ca>.  Tcpdump has been tested under
+  both the vanilla Enetfilter interface, and the extended interface
+  (#ifdef'd by IBMRTPC) present in the MERIT version of the Enetfilter.
+
+- TFTP packets are now printed (requests only).
+
+- BOOTP packets are now printed.
+
+- SNMP packets are now printed. (thanks to John LoVerso of Xylogics).
+
+- Sparc architectures, including the Sparcstation-1, are now
+  supported thanks to Steve McCanne and Craig Leres.
+
+- SunOS 4 is now supported thanks to Micky Liu of Columbia
+  University (micky@cunixc.cc.columbia.edu).
+
+- IP options are now printed.
+
+- RIP packets are now printed.
+
+- There's a -v flag that prints out more information than the
+  default (e.g., it will enable printing of IP ttl, tos and id)
+  and -q flag that prints out less (e.g., it will disable
+  interpretation of AppleTalk-in-UDP).
+
+- The grammar has undergone substantial changes (if you have an
+  earlier version of tcpdump, you should re-read the manual
+  entry).
+
+  The most useful change is the addition of an expression
+  syntax that lets you filter on arbitrary fields or values in the
+  packet.  E.g., "ip[0] > 0x45" would print only packets with IP
+  options, "tcp[13] & 3 != 0" would print only TCP SYN and FIN
+  packets.
+
+  The most painful change is that concatenation no longer means
+  "and" -- e.g., you have to say "host foo and port bar" instead
+  of "host foo port bar".  The up side to this down is that
+  repeated qualifiers can be omitted, making most filter
+  expressions shorter.  E.g., you can now say "ip host foo and
+  (bar or baz)" to look at ip traffic between hosts foo and bar or
+  between hosts foo and baz.  [The old way of saying this was "ip
+  host foo and (ip host bar or ip host baz)".]
+
+v2.0 Sun Jan 13 12:20:40 PST 1991
+
+- Initial public release.

+@(#) $Header: /tcpdump/master/tcpdump/Attic/INSTALL,v 1.36 1999-10-07 23:47:09 mcr Exp $ (LBL)
+
+If you have not built libpcap, do so first.  See the README
+file in this directory for the ftp location.
+
+You will need an ANSI C compiler to build tcpdump. The configure script
+will abort if your compiler is not ANSI compliant. If this happens, use
+the GNU C compiler, available via anonymous ftp:
+
+	ftp://prep.ai.mit.edu/pub/gnu/gcc.tar.gz
+
+After libpcap has been built (either install it with "make install" and
+"make install-incl" or make sure both the libpcap and tcpdump source
+trees are in the same directory), edit the BINDEST and MANDEST paths in
+Makefile.in and run ./configure (a shell script).  "configure" will
+determine your system attributes and generate an appropriate Makefile
+from Makefile.in.  Now build tcpdump by running "make".
+
+If everything builds ok, su and type "make install" (and optionally
+"make install-man). This will install tcpdump and the manual entry. By
+default, tcpdump is installed with group execute permissions. The group
+used depends on your os. In addition, BPF packet access is controlled
+by permissions to /dev/bpf0. In any case, DO NOT give untrusted users
+the capability of running tcpdump. Tcpdump can capture any traffic on
+your net, including passwords.
+
+Note that tcpdump is shipped with some systems, for example, DEC/OSF
+and BSD/386.  Remember to remove or rename the installed binary
+when upgrading.
+
+If you use Linux, this version of libpcap is known to compile and run
+under Red Hat 4.0 with the 2.0.25 kernel. It may work with earlier 2.X
+versions but is guaranteed not to work with 1.X kernels.
+
+If you use OSF 4, note that that there appears to be some serious bugs
+with the stock C compiler. The configure code fragments that detect if
+the ether_header and ether_arp structs use the ether_addr struct
+generates warnings instead of fatal errors (?!?!) This makes configure
+think that the ether_arp struct is used when in fact it is not. To get
+around this, delete:
+

+from the Makefile after running configure (and before attempting to
+compile tcpdump.
+
+Another workaround is to use gcc.
+
+If your system is not one which we have tested tcpdump on, you may have
+to modify the configure script and Makefile.in. Please send us patches
+for any modifications you need to make. However, we are not interested
+in ascii packet printer patches. We believe adding this feature would
+make it too easy for crackers who do not have the programming skills
+needed to write a password sniffer to grab clear text passwords.

+TCPDUMP 3.4
+Lawrence Berkeley National Laboratory
+Network Research Group
+tcpdump@ee.lbl.gov
+ftp://ftp.ee.lbl.gov/tcpdump.tar.Z
+
+This directory contains source code for tcpdump, a tool for network
+monitoring and data acquisition.  The original distribution is
+available via anonymous ftp to ftp.ee.lbl.gov, in tcpdump.tar.Z.
+
+Tcpdump now uses libpcap, a system-independent interface for user-level
+packet capture.  Before building tcpdump, you must first retrieve and
+build libpcap, also from LBL, in:
+
+	ftp://ftp.ee.lbl.gov/libpcap.tar.Z
+
+Once libpcap is built (either install it or make sure it's in
+../libpcap), you can build tcpdump using the procedure in the INSTALL
+file.
+
+The program is loosely based on SMI's "etherfind" although none of the
+etherfind code remains.  It was originally written by Van Jacobson as
+part of an ongoing research project to investigate and improve tcp and
+internet gateway performance.  The parts of the program originally
+taken from Sun's etherfind were later re-written by Steven McCanne of
+LBL.  To insure that there would be no vestige of proprietary code in
+tcpdump, Steve wrote these pieces from the specification given by the
+manual entry, with no access to the source of tcpdump or etherfind.
+
+Over the past few years, tcpdump has been steadily improved by the
+excellent contributions from the Internet community (just browse
+through the CHANGES file).  We are grateful for all the input.
+
+Richard Stevens gives an excellent treatment of the Internet protocols
+in his book ``TCP/IP Illustrated, Volume 1''. If you want to learn more
+about tcpdump and how to interpret its output, pick up this book.
+
+Some tools for viewing and analyzing tcpdump trace files are available
+from the Internet Traffic Archive:
+
+	http://www.acm.org/sigcomm/ITA/
+
+Another tool that tcpdump users might find useful is tcpslice:
+
+	ftp://ftp.ee.lbl.gov/tcpslice.tar.Z
+
+It is a program that can be used to extract portions of tcpdump binary
+trace files. See the above distribution for further details and
+documentation.
+
+Problems, bugs, questions, desirable enhancements, source code
+contributions, etc., should be sent to the email address
+"tcpdump@ee.lbl.gov".

+-------------------------------------
+This directory also contains some short awk programs intended as
+examples of ways to reduce tcpdump data when you're tracking
+particular network problems:
+
+send-ack.awk
+	Simplifies the tcpdump trace for an ftp (or other unidirectional
+	tcp transfer).  Since we assume that one host only sends and
+	the other only acks, all address information is left off and
+	we just note if the packet is a "send" or an "ack".
+
+	There is one output line per line of the original trace.
+	Field 1 is the packet time in decimal seconds, relative
+	to the start of the conversation.  Field 2 is delta-time
+	from last packet.  Field 3 is packet type/direction.
+	"Send" means data going from sender to receiver, "ack"
+	means an ack going from the receiver to the sender.  A
+	preceding "*" indicates that the data is a retransmission.
+	A preceding "-" indicates a hole in the sequence space
+	(i.e., missing packet(s)), a "#" means an odd-size (not max
+	seg size) packet.  Field 4 has the packet flags
+	(same format as raw trace).  Field 5 is the sequence
+	number (start seq. num for sender, next expected seq number
+	for acks).  The number in parens following an ack is
+	the delta-time from the first send of the packet to the
+	ack.  A number in parens following a send is the
+	delta-time from the first send of the packet to the
+	current send (on duplicate packets only).  Duplicate
+	sends or acks have a number in square brackets showing
+	the number of duplicates so far.
+
+	Here is a short sample from near the start of an ftp:
+		3.00    0.20   send . 512
+		3.20    0.20    ack . 1024  (0.20)
+		3.20    0.00   send P 1024
+		3.40    0.20    ack . 1536  (0.20)
+		3.80    0.40 * send . 0  (3.80) [2]
+		3.82    0.02 *  ack . 1536  (0.62) [2]
+	Three seconds into the conversation, bytes 512 through 1023
+	were sent.  200ms later they were acked.  Shortly thereafter
+	bytes 1024-1535 were sent and again acked after 200ms.
+	Then, for no apparent reason, 0-511 is retransmitted, 3.8
+	seconds after its initial send (the round trip time for this
+	ftp was 1sec, +-500ms).  Since the receiver is expecting
+	1536, 1536 is re-acked when 0 arrives.
+
+packetdat.awk
+	Computes chunk summary data for an ftp (or similar
+	unidirectional tcp transfer). [A "chunk" refers to
+	a chunk of the sequence space -- essentially the packet
+	sequence number divided by the max segment size.]
+
+	A summary line is printed showing the number of chunks,
+	the number of packets it took to send that many chunks
+	(if there are no lost or duplicated packets, the number
+	of packets should equal the number of chunks) and the
+	number of acks.
+
+	Following the summary line is one line of information
+	per chunk.  The line contains eight fields:
+	   1 - the chunk number
+	   2 - the start sequence number for this chunk
+	   3 - time of first send
+	   4 - time of last send
+	   5 - time of first ack
+	   6 - time of last ack
+	   7 - number of times chunk was sent
+	   8 - number of times chunk was acked
+	(all times are in decimal seconds, relative to the start
+	of the conversation.)
+
+	As an example, here is the first part of the output for
+	an ftp trace:
+
+	# 134 chunks.  536 packets sent.  508 acks.
+	1       1       0.00    5.80    0.20    0.20    4       1
+	2       513     0.28    6.20    0.40    0.40    4       1
+	3       1025    1.16    6.32    1.20    1.20    4       1
+	4       1561    1.86    15.00   2.00    2.00    6       1
+	5       2049    2.16    15.44   2.20    2.20    5       1
+	6       2585    2.64    16.44   2.80    2.80    5       1
+	7       3073    3.00    16.66   3.20    3.20    4       1
+	8       3609    3.20    17.24   3.40    5.82    4       11
+	9       4097    6.02    6.58    6.20    6.80    2       5
+
+	This says that 134 chunks were transferred (about 70K
+	since the average packet size was 512 bytes).  It took
+	536 packets to transfer the data (i.e., on the average
+	each chunk was transmitted four times).  Looking at,
+	say, chunk 4, we see it represents the 512 bytes of
+	sequence space from 1561 to 2048.  It was first sent
+	1.86 seconds into the conversation.  It was last
+	sent 15 seconds into the conversation and was sent
+	a total of 6 times (i.e., it was retransmitted every
+	2 seconds on the average).  It was acked once, 140ms
+	after it first arrived.
+
+stime.awk
+atime.awk
+	Output one line per send or ack, respectively, in the form
+		<time> <seq. number>
+	where <time> is the time in seconds since the start of the
+	transfer and <seq. number> is the sequence number being sent
+	or acked.  I typically plot this data looking for suspicious
+	patterns.
+
+
+The problem I was looking at was the bulk-data-transfer
+throughput of medium delay network paths (1-6 sec.  round trip
+time) under typical DARPA Internet conditions.  The trace of the
+ftp transfer of a large file was used as the raw data source.
+The method was:
+
+  - On a local host (but not the Sun running tcpdump), connect to
+    the remote ftp.
+
+  - On the monitor Sun, start the trace going.  E.g.,
+      tcpdump host local-host and remote-host and port ftp-data >tracefile
+
+  - On local, do either a get or put of a large file (~500KB),
+    preferably to the null device (to minimize effects like
+    closing the receive window while waiting for a disk write).
+
+  - When transfer is finished, stop tcpdump.  Use awk to make up
+    two files of summary data (maxsize is the maximum packet size,
+    tracedata is the file of tcpdump tracedata):
+      awk -f send-ack.awk packetsize=avgsize tracedata >sa
+      awk -f packetdat.awk packetsize=avgsize tracedata >pd
+
+  - While the summary data files are printing, take a look at
+    how the transfer behaved:
+      awk -f stime.awk tracedata | xgraph
+    (90% of what you learn seems to happen in this step).
+
+  - Do all of the above steps several times, both directions,
+    at different times of day, with different protocol
+    implementations on the other end.
+
+  - Using one of the Unix data analysis packages (in my case,
+    S and Gary Perlman's Unix|Stat), spend a few months staring
+    at the data.
+
+  - Change something in the local protocol implementation and
+    redo the steps above.
+
+  - Once a week, tell your funding agent that you're discovering
+    wonderful things and you'll write up that research report
+    "real soon now".

+dnl This test is for network applications that need socket() and
+dnl gethostbyname() -ish functions.  Under Solaris, those applications
+dnl need to link with "-lsocket -lnsl".  Under IRIX, they need to link
+dnl with "-lnsl" but should *not* link with "-lsocket" because
+dnl libsocket.a breaks a number of things (for instance:
+dnl gethostbyname() under IRIX 5.2, and snoop sockets under most
+dnl versions of IRIX).
+dnl
+dnl Unfortunately, many application developers are not aware of this,
+dnl and mistakenly write tests that cause -lsocket to be used under
+dnl IRIX.  It is also easy to write tests that cause -lnsl to be used
+dnl under operating systems where neither are necessary (or useful),
+dnl such as SunOS 4.1.4, which uses -lnsl for TLI.
+dnl
+dnl This test exists so that every application developer does not test
+dnl this in a different, and subtly broken fashion.
+
+dnl It has been argued that this test should be broken up into two
+dnl seperate tests, one for the resolver libraries, and one for the
+dnl libraries necessary for using Sockets API. Unfortunately, the two
+dnl are carefully intertwined and allowing the autoconf user to use
+dnl them independantly potentially results in unfortunate ordering
+dnl dependancies -- as such, such component macros would have to
+dnl carefully use indirection and be aware if the other components were
+dnl executed. Since other autoconf macros do not go to this trouble,
+dnl and almost no applications use sockets without the resolver, this
+dnl complexity has not been implemented.
+dnl
+dnl The check for libresolv is in case you are attempting to link
+dnl statically and happen to have a libresolv.a lying around (and no

+ * Compressed packet format:
+ *
+ * The first octet contains the packet type (top 3 bits), TCP
+ * 'push' bit, and flags that indicate which of the 4 TCP sequence
+ * numbers have changed (bottom 5 bits).  The next octet is a
+ * conversation number that associates a saved IP/TCP header with
+ * the compressed packet.  The next two octets are the TCP checksum
+ * from the original datagram.  The next 0 to 15 octets are
+ * sequence number changes, one change per bit set in the header
+ * (there may be no changes and there are two special cases where
+ * the receiver implicitly knows what changed -- see below).
+ *
+ * There are 5 numbers which can change (they are always inserted
+ * in the following order): TCP urgent pointer, window,
+ * acknowlegement, sequence number and IP ID.  (The urgent pointer
+ * is different from the others in that its value is sent, not the
+ * change in value.)  Since typical use of SLIP links is biased
+ * toward small packets (see comments on MTU/MSS below), changes
+ * use a variable length coding with one octet for numbers in the
+ * range 1 - 255 and 3 octets (0, MSB, LSB) for numbers in the
+ * range 256 - 65535 or 0.  (If the change in sequence number or
+ * ack is more than 65535, an uncompressed packet is sent.)

+ * Packet types (must not conflict with IP protocol version)
+ *
+ * The top nibble of the first octet is the packet type.  There are
+ * three possible types: IP (not proto TCP or tcp with one of the
+ * control flags set); uncompressed TCP (a normal IP/TCP packet but
+ * with the 8-bit protocol field replaced by an 8-bit connection id --
+ * this type of packet syncs the sender & receiver); and compressed
+ * TCP (described above).
+ *
+ * LSB of 4-bit field is TCP "PUSH" bit (a worthless anachronism) and
+ * is logically part of the 4-bit "changes" field that follows.  Top
+ * three bits are actual packet type.  For backward compatibility
+ * and in the interest of conserving bits, numbers are chosen so the
+ * IP protocol version number (4) which normally appears in this nibble

+ *
+ * NOTE:  This is a very preliminary hack for FDDI support.
+ * There are all sorts of wired in constants & nothing (yet)
+ * to print SMT packets as anything other than hex dumps.
+ * Most of the necessary changes are waiting on my redoing
+ * the "header" that a kernel fddi driver supplies to bpf:  I
+ * want it to look like one byte of 'direction' (0 or 1
+ * depending on whether the packet was inbound or outbound),
+ * two bytes of system/driver dependent data (anything an
+ * implementor thinks would be useful to filter on and/or
+ * save per-packet, then the real 21-byte FDDI header.
+ * Steve McCanne & I have also talked about adding the
+ * 'direction' byte to all bpf headers (e.g., in the two
+ * bytes of padding on an ethernet header).  It's not clear
+ * we could do this in a backwards compatible way & we hate
+ * the idea of an incompatible bpf change.  Discussions are
+ * proceeding.
+ *
+ * Also, to really support FDDI (and better support 802.2
+ * over ethernet) we really need to re-think the rather simple
+ * minded assumptions about fixed length & fixed format link
+ * level headers made in gencode.c.  One day...

+.SH DESCRIPTION
+.LP
+\fITcpdump\fP prints out the headers of packets on a network interface
+that match the boolean \fIexpression\fP.
+.LP
+.B Under SunOS with nit or bpf:
+To run
+.I tcpdump
+you must have read access to
+.I /dev/nit
+or
+.IR /dev/bpf* .
+.B Under Solaris with dlpi:
+You must have read access to the network pseudo device, e.g.
+.IR /dev/le .
+.B Under HP-UX with dlpi:
+You must be root or it must be installed setuid to root.
+.B Under IRIX with snoop:
+You must be root or it must be installed setuid to root.
+.B Under Linux:
+You must be root or it must be installed setuid to root.
+.B Under Ultrix and Digital UNIX:
+Once the super-user has enabled promiscuous-mode operation using
+.IR pfconfig (8),
+any user may run
+.BR tcpdump .
+.B Under BSD:
+You must have read access to
+.IR /dev/bpf* .
+.SH OPTIONS
+.TP
+.B \-a
+Attempt to convert network and broadcast addresses to names.
+.TP
+.B \-c
+Exit after receiving \fIcount\fP packets.
+.TP
+.B \-d
+Dump the compiled packet-matching code in a human readable form to
+standard output and stop.
+.TP
+.B \-dd
+Dump packet-matching code as a
+.B C
+program fragment.
+.TP
+.B \-ddd
+Dump packet-matching code as decimal numbers (preceded with a count).
+.TP
+.B \-e
+Print the link-level header on each dump line.
+.TP
+.B \-f
+Print `foreign' internet addresses numerically rather than symbolically
+(this option is intended to get around serious brain damage in
+Sun's yp server \(em usually it hangs forever translating non-local
+internet numbers).
+.TP
+.B \-F
+Use \fIfile\fP as input for the filter expression.
+An additional expression given on the command line is ignored.
+.TP
+.B \-i
+Listen on \fIinterface\fP.
+If unspecified, \fItcpdump\fP searches the system interface list for the
+lowest numbered, configured up interface (excluding loopback).
+Ties are broken by choosing the earliest match.
+.TP
+.B \-l
+Make stdout line buffered.  Useful if you want to see the data
+while capturing it.  E.g.,
+.br
+``tcpdump\ \ \-l\ \ |\ \ tee dat'' or
+``tcpdump\ \ \-l \ \ > dat\ \ &\ \ tail\ \ \-f\ \ dat''.
+.TP
+.B \-n
+Don't convert addresses (i.e., host addresses, port numbers, etc.) to names.
+.TP
+.B \-N
+Don't print domain name qualification of host names.  E.g.,
+if you give this flag then \fItcpdump\fP will print ``nic''
+instead of ``nic.ddn.mil''.
+.TP
+.B \-O
+Do not run the packet-matching code optimizer.  This is useful only
+if you suspect a bug in the optimizer.
+.TP
+.B \-p
+\fIDon't\fP put the interface
+into promiscuous mode.  Note that the interface might be in promiscuous
+mode for some other reason; hence, `-p' cannot be used as an abbreviation for
+`ether host {local-hw-addr} or ether broadcast'.
+.TP
+.B \-q
+Quick (quiet?) output.  Print less protocol information so output
+lines are shorter.
+.TP
+.B \-r
+Read packets from \fIfile\fR (which was created with the -w option).
+Standard input is used if \fIfile\fR is ``-''.
+.TP
+.B \-s
+Snarf \fIsnaplen\fP bytes of data from each packet rather than the
+default of 68 (with SunOS's NIT, the minimum is actually 96).
+68 bytes is adequate for IP, ICMP, TCP
+and UDP but may truncate protocol information from name server and NFS
+packets (see below).  Packets truncated because of a limited snapshot
+are indicated in the output with ``[|\fIproto\fP]'', where \fIproto\fP
+is the name of the protocol level at which the truncation has occurred.
+Note that taking larger snapshots both increases
+the amount of time it takes to process packets and, effectively,
+decreases the amount of packet buffering.  This may cause packets to be
+lost.  You should limit \fIsnaplen\fP to the smallest number that will
+capture the protocol information you're interested in.
+.TP
+.B \-T
+Force packets selected by "\fIexpression\fP" to be interpreted the
+specified \fItype\fR. Currently known types are
+\fBrpc\fR (Remote Procedure Call),
+\fBrtp\fR (Real-Time Applications protocol),
+\fBrtcp\fR (Real-Time Applications control protocol),
+\fBvat\fR (Visual Audio Tool),
+and
+\fBwb\fR (distributed White Board).
+.TP
+.B \-S
+Print absolute, rather than relative, TCP sequence numbers.
+.TP
+.B \-t
+\fIDon't\fP print a timestamp on each dump line.
+.TP
+.B \-tt
+Print an unformatted timestamp on each dump line.
+.TP
+.B \-v
+(Slightly more) verbose output.  For example, the time to live
+and type of service information in an IP packet is printed.
+.TP
+.B \-vv
+Even more verbose output.  For example, additional fields are
+printed from NFS reply packets.
+.TP
+.B \-w
+Write the raw packets to \fIfile\fR rather than parsing and printing
+them out.  They can later be printed with the \-r option.
+Standard output is used if \fIfile\fR is ``-''.
+.TP
+.B \-x
+Print each packet (minus its link level header) in hex.
+The smaller of the entire packet or
+.I snaplen
+bytes will be printed.
+.IP "\fI expression\fP"
+.RS
+selects which packets will be dumped.  If no \fIexpression\fP
+is given, all packets on the net will be dumped.  Otherwise,
+only packets for which \fIexpression\fP is `true' will be dumped.
+.LP
+The \fIexpression\fP consists of one or more
+.I primitives.
+Primitives usually consist of an
+.I id
+(name or number) preceded by one or more qualifiers.  There are three
+different kinds of qualifier:
+.IP \fItype\fP
+qualifiers say what kind of thing the id name or number refers to.
+Possible types are
+.BR host ,
+.B net
+and
+.BR port .
+E.g., `host foo', `net 128.3', `port 20'.  If there is no type
+qualifier,
+.B host
+is assumed.
+.IP \fIdir\fP
+qualifiers specify a particular transfer direction to and/or from
+.I id.
+Possible directions are
+.BR src ,
+.BR dst ,
+.B "src or dst"
+and
+.B "src and"
+.BR dst .
+E.g., `src foo', `dst net 128.3', `src or dst port ftp-data'.  If
+there is no dir qualifier,
+.B "src or dst"
+is assumed.
+For `null' link layers (i.e. point to point protocols such as slip) the
+.B inbound
+and
+.B outbound
+qualifiers can be used to specify a desired direction.
+.IP \fIproto\fP
+qualifiers restrict the match to a particular protocol.  Possible
+protos are:
+.BR ether ,
+.BR fddi ,
+.BR ip ,
+.BR arp ,
+.BR rarp ,
+.BR decnet ,
+.BR lat ,
+.BR sca ,
+.BR moprc ,
+.BR mopdl ,
+.B tcp
+and
+.BR udp .
+E.g., `ether src foo', `arp net 128.3', `tcp port 21'.  If there is
+no proto qualifier, all protocols consistent with the type are
+assumed.  E.g., `src foo' means `(ip or arp or rarp) src foo'
+(except the latter is not legal syntax), `net bar' means `(ip or
+arp or rarp) net bar' and `port 53' means `(tcp or udp) port 53'.
+.LP
+[`fddi' is actually an alias for `ether'; the parser treats them
+identically as meaning ``the data link level used on the specified
+network interface.''  FDDI headers contain Ethernet-like source
+and destination addresses, and often contain Ethernet-like packet
+types, so you can filter on these FDDI fields just as with the
+analogous Ethernet fields.  FDDI headers also contain other fields,
+but you cannot name them explicitly in a filter expression.]
+.LP
+In addition to the above, there are some special `primitive' keywords
+that don't follow the pattern:
+.BR gateway ,
+.BR broadcast ,
+.BR less ,
+.B greater
+and arithmetic expressions.  All of these are described below.
+.LP
+More complex filter expressions are built up by using the words
+.BR and ,
+.B or
+and
+.B not
+to combine primitives.  E.g., `host foo and not port ftp and not port ftp-data'.
+To save typing, identical qualifier lists can be omitted.  E.g.,
+`tcp dst port ftp or ftp-data or domain' is exactly the same as
+`tcp dst port ftp or tcp dst port ftp-data or tcp dst port domain'.
+.LP
+Allowable primitives are:
+.IP "\fBdst host \fIhost\fR"
+True if the IP destination field of the packet is \fIhost\fP,
+which may be either an address or a name.
+.IP "\fBsrc host \fIhost\fR"
+True if the IP source field of the packet is \fIhost\fP.
+.IP "\fBhost \fIhost\fP
+True if either the IP source or destination of the packet is \fIhost\fP.
+Any of the above host expressions can be prepended with the keywords,
+\fBip\fP, \fBarp\fP, or \fBrarp\fP as in:
+.in +.5i
+.nf
+\fBip host \fIhost\fR
+.fi
+.in -.5i
+which is equivalent to:
+.in +.5i
+.nf
+\fBether proto \fI\\ip\fB and host \fIhost\fR
+.fi
+.in -.5i
+If \fIhost\fR is a name with multiple IP addresses, each address will
+be checked for a match.
+.IP "\fBether dst \fIehost\fP
+True if the ethernet destination address is \fIehost\fP.  \fIEhost\fP
+may be either a name from /etc/ethers or a number (see
+.IR ethers (3N)
+for numeric format).
+.IP "\fBether src \fIehost\fP
+True if the ethernet source address is \fIehost\fP.
+.IP "\fBether host \fIehost\fP
+True if either the ethernet source or destination address is \fIehost\fP.
+.IP "\fBgateway\fP \fIhost\fP
+True if the packet used \fIhost\fP as a gateway.  I.e., the ethernet
+source or destination address was \fIhost\fP but neither the IP source
+nor the IP destination was \fIhost\fP.  \fIHost\fP must be a name and
+must be found in both /etc/hosts and /etc/ethers.  (An equivalent
+expression is
+.in +.5i
+.nf
+\fBether host \fIehost \fBand not host \fIhost\fR
+.fi
+.in -.5i
+which can be used with either names or numbers for \fIhost / ehost\fP.)
+.IP "\fBdst net \fInet\fR"
+True if the IP destination address of the packet has a network
+number of \fInet\fP. \fINet\fP may be either a name from /etc/networks
+or a network number (see \fInetworks(4)\fP for details).
+.IP "\fBsrc net \fInet\fR"
+True if the IP source address of the packet has a network
+number of \fInet\fP.
+.IP "\fBnet \fInet\fR"
+True if either the IP source or destination address of the packet has a network
+number of \fInet\fP.
+.IP "\fBnet \fInet\fR \fBmask \fImask\fR"
+True if the IP address matches \fInet\fR with the specific netmask.
+May be qualified with \fBsrc\fR or \fBdst\fR.
+.IP "\fBnet \fInet\fR/\fIlen\fR"
+True if the IP address matches \fInet\fR a netmask \fIlen\fR bits wide.
+May be qualified with \fBsrc\fR or \fBdst\fR.
+.IP "\fBdst port \fIport\fR"
+True if the packet is ip/tcp or ip/udp and has a
+destination port value of \fIport\fP.
+The \fIport\fP can be a number or a name used in /etc/services (see
+.IR tcp (4P)
+and
+.IR udp (4P)).
+If a name is used, both the port
+number and protocol are checked.  If a number or ambiguous name is used,
+only the port number is checked (e.g., \fBdst port 513\fR will print both
+tcp/login traffic and udp/who traffic, and \fBport domain\fR will print
+both tcp/domain and udp/domain traffic).
+.IP "\fBsrc port \fIport\fR"
+True if the packet has a source port value of \fIport\fP.
+.IP "\fBport \fIport\fR"
+True if either the source or destination port of the packet is \fIport\fP.
+Any of the above port expressions can be prepended with the keywords,
+\fBtcp\fP or \fBudp\fP, as in:
+.in +.5i
+.nf
+\fBtcp src port \fIport\fR
+.fi
+.in -.5i
+which matches only tcp packets whose source port is \fIport\fP.
+.IP "\fBless \fIlength\fR"
+True if the packet has a length less than or equal to \fIlength\fP.
+This is equivalent to:
+.in +.5i
+.nf
+\fBlen <= \fIlength\fP.
+.fi
+.in -.5i
+.IP "\fBgreater \fIlength\fR"
+True if the packet has a length greater than or equal to \fIlength\fP.
+This is equivalent to:
+.in +.5i
+.nf
+\fBlen >= \fIlength\fP.
+.fi
+.in -.5i
+.IP "\fBip proto \fIprotocol\fR"
+True if the packet is an ip packet (see
+.IR ip (4P))
+of protocol type \fIprotocol\fP.
+\fIProtocol\fP can be a number or one of the names
+\fIicmp\fP, \fIigrp\fP, \fIudp\fP, \fInd\fP, or \fItcp\fP.
+Note that the identifiers \fItcp\fP, \fIudp\fP, and \fIicmp\fP are also
+keywords and must be escaped via backslash (\\), which is \\\\ in the C-shell.
+.IP "\fBether broadcast\fR"
+True if the packet is an ethernet broadcast packet.  The \fIether\fP
+keyword is optional.
+.IP "\fBip broadcast\fR"
+True if the packet is an IP broadcast packet.  It checks for both
+the all-zeroes and all-ones broadcast conventions, and looks up
+the local subnet mask.
+.IP "\fBether multicast\fR"
+True if the packet is an ethernet multicast packet.  The \fIether\fP
+keyword is optional.
+This is shorthand for `\fBether[0] & 1 != 0\fP'.
+.IP "\fBip multicast\fR"
+True if the packet is an IP multicast packet.
+.IP  "\fBether proto \fIprotocol\fR"
+True if the packet is of ether type \fIprotocol\fR.
+\fIProtocol\fP can be a number or a name like
+\fIip\fP, \fIarp\fP, or \fIrarp\fP.
+Note these identifiers are also keywords
+and must be escaped via backslash (\\).
+[In the case of FDDI (e.g., `\fBfddi protocol arp\fR'), the
+protocol identification comes from the 802.2 Logical Link Control
+(LLC) header, which is usually layered on top of the FDDI header.
+\fITcpdump\fP assumes, when filtering on the protocol identifier,
+that all FDDI packets include an LLC header, and that the LLC header
+is in so-called SNAP format.]
+.IP "\fBdecnet src \fIhost\fR"
+True if the DECNET source address is
+.IR host ,
+which may be an address of the form ``10.123'', or a DECNET host
+name.  [DECNET host name support is only available on Ultrix systems
+that are configured to run DECNET.]
+.IP "\fBdecnet dst \fIhost\fR"
+True if the DECNET destination address is
+.IR host .
+.IP "\fBdecnet host \fIhost\fR"
+True if either the DECNET source or destination address is
+.IR host .
+.IP "\fBip\fR, \fBarp\fR, \fBrarp\fR, \fBdecnet\fR"
+Abbreviations for:
+.in +.5i
+.nf
+\fBether proto \fIp\fR
+.fi
+.in -.5i
+where \fIp\fR is one of the above protocols.
+.IP "\fBlat\fR, \fBmoprc\fR, \fBmopdl\fR"
+Abbreviations for:
+.in +.5i
+.nf
+\fBether proto \fIp\fR
+.fi
+.in -.5i
+where \fIp\fR is one of the above protocols.
+Note that
+\fItcpdump\fP does not currently know how to parse these protocols.
+.IP  "\fBtcp\fR, \fBudp\fR, \fBicmp\fR"
+Abbreviations for:
+.in +.5i
+.nf
+\fBip proto \fIp\fR
+.fi
+.in -.5i
+where \fIp\fR is one of the above protocols.
+.IP  "\fIexpr relop expr\fR"
+True if the relation holds, where \fIrelop\fR is one of >, <, >=, <=, =, !=,
+and \fIexpr\fR is an arithmetic expression composed of integer constants
+(expressed in standard C syntax), the normal binary operators
+[+, -, *, /, &, |], a length operator, and special packet data accessors.
+To access
+data inside the packet, use the following syntax:
+.in +.5i
+.nf
+\fIproto\fB [ \fIexpr\fB : \fIsize\fB ]\fR
+.fi
+.in -.5i
+\fIProto\fR is one of \fBether, fddi,
+ip, arp, rarp, tcp, udp, \fRor \fBicmp\fR, and
+indicates the protocol layer for the index operation.
+The byte offset, relative to the indicated protocol layer, is
+given by \fIexpr\fR.
+\fISize\fR is optional and indicates the number of bytes in the
+field of interest; it can be either one, two, or four, and defaults to one.
+The length operator, indicated by the keyword \fBlen\fP, gives the
+length of the packet.
+
+For example, `\fBether[0] & 1 != 0\fP' catches all multicast traffic.
+The expression `\fBip[0] & 0xf != 5\fP'
+catches all IP packets with options. The expression
+`\fBip[6:2] & 0x1fff = 0\fP'
+catches only unfragmented datagrams and frag zero of fragmented datagrams.
+This check is implicitly applied to the \fBtcp\fP and \fBudp\fP
+index operations.
+For instance, \fBtcp[0]\fP always means the first
+byte of the TCP \fIheader\fP, and never means the first byte of an
+intervening fragment.
+.LP
+Primitives may be combined using:
+.IP
+A parenthesized group of primitives and operators
+(parentheses are special to the Shell and must be escaped).
+.IP
+Negation (`\fB!\fP' or `\fBnot\fP').
+.IP
+Concatenation (`\fB&&\fP' or `\fBand\fP').
+.IP
+Alternation (`\fB||\fP' or `\fBor\fP').
+.LP
+Negation has highest precedence.
+Alternation and concatenation have equal precedence and associate
+left to right.  Note that explicit \fBand\fR tokens, not juxtaposition,
+are now required for concatenation.
+.LP
+If an identifier is given without a keyword, the most recent keyword
+is assumed.
+For example,
+.in +.5i
+.nf
+\fBnot host vs and ace\fR
+.fi
+.in -.5i
+is short for
+.in +.5i
+.nf
+\fBnot host vs and host ace\fR
+.fi
+.in -.5i
+which should not be confused with
+.in +.5i
+.nf
+\fBnot ( host vs or ace )\fR
+.fi
+.in -.5i
+.LP
+Expression arguments can be passed to tcpdump as either a single argument
+or as multiple arguments, whichever is more convenient.
+Generally, if the expression contains Shell metacharacters, it is
+easier to pass it as a single, quoted argument.
+Multiple arguments are concatenated with spaces before being parsed.

+On FDDI networks, the  '-e' option causes \fItcpdump\fP to print
+the `frame control' field,  the source and destination addresses,
+and the packet length.  (The `frame control' field governs the
+interpretation of the rest of the packet.  Normal packets (such
+as those containing IP datagrams) are `async' packets, with a priority
+value between 0 and 7; for example, `\fBasync4\fR'.  Such packets
+are assumed to contain an 802.2 Logical Link Control (LLC) packet;

+The packet type is printed first.
+The three types are \fIip\fP, \fIutcp\fP, and \fIctcp\fP.
+No further link information is printed for \fIip\fR packets.
+For TCP packets, the connection identifier is printed following the type.
+If the packet is compressed, its encoded header is printed out.
+The special cases are printed out as
+\fB*S+\fIn\fR and \fB*SA+\fIn\fR, where \fIn\fR is the amount by which
+the sequence number (or sequence number and ack) has changed.
+If it is not a special case,
+zero or more changes are printed.
+A change is indicated by U (urgent pointer), W (window), A (ack),
+S (sequence number), and I (packet ID), followed by a delta (+n or -n),
+or a new value (=n).
+Finally, the amount of data in the packet and compressed header length
+are printed.

+Csam replies with a similar packet except it includes a piggy-backed
+ack for rtsg's SYN.  Rtsg then acks csam's SYN.  The `.' means no
+flags were set.
+The packet contained no data so there is no data sequence number.
+Note that the ack sequence
+number is a small integer (1).  The first time \fBtcpdump\fP sees a
+tcp `conversation', it prints the sequence number from the packet.
+On subsequent packets of the conversation, the difference between
+the current packet's sequence number and this initial sequence number
+is printed.  This means that sequence numbers after the
+first can be interpreted
+as relative byte positions in the conversation's data stream (with the
+first data byte each direction being `1').  `-S' will override this
+feature, causing the original sequence numbers to be output.

+On the 6th line, rtsg sends csam 19 bytes of data (bytes 2 through 20
+in the rtsg \(-> csam side of the conversation).
+The PUSH flag is set in the packet.
+On the 7th line, csam says it's received data sent by rtsg up to
+but not including byte 21.  Most of this data is apparently sitting in the
+socket buffer since csam's receive window has gotten 19 bytes smaller.
+Csam also sends one byte of data to rtsg in this packet.

+csam sends two bytes of urgent, pushed data to rtsg.

+If the snapshot was small enough that \fBtcpdump\fP didn't capture

+be interpreted.  If the header contains a bogus option (one with a length
+that's either too small or beyond the end of the header), tcpdump reports
+it as ``[\fIbad opt\fP]'' and does not interpret any further options (since
+it's impossible to tell where they start).  If the header length indicates

+.RE
+There are a couple of things to note here:  First, addresses in the
+2nd line don't include port numbers.  This is because the TCP
+protocol information is all in the first fragment and we have no idea
+what the port or sequence numbers are when we print the later fragments.
+Second, the tcp sequence information in the first line is printed as if there
+were 308 bytes of user data when, in fact, there are 512 bytes (308 in
+the first frag and 204 in the second).  If you are looking for holes
+in the sequence space or trying to match up acks
+with packets, this can fool you.
+.LP
+A packet with the IP \fIdon't fragment\fP flag is marked with a
+trailing \fB(DF)\fP.
+.HD
+Timestamps
+.LP
+By default, all output lines are preceded by a timestamp.  The timestamp
+is the current clock time in the form
+.RS
+.nf
+\fIhh:mm:ss.frac\fP
+.fi
+.RE
+and is as accurate as the kernel's clock.
+The timestamp reflects the time the kernel first saw the packet.  No attempt
+is made to account for the time lag between when the
+ethernet interface removed the packet from the wire and when the kernel
+serviced the `new packet' interrupt.

+.SH BUGS
+Please send bug reports to tcpdump@ee.lbl.gov.
+.LP
+NIT doesn't let you watch your own outbound traffic, BPF will.
+We recommend that you use the latter.
+.LP
+Some attempt should be made to reassemble IP fragments or, at least
+to compute the right length for the higher level protocol.
+.LP
+Name server inverse queries are not dumped correctly: The (empty)
+question section is printed rather than real query in the answer
+section.  Some believe that inverse queries are themselves a bug and
+prefer to fix the program generating them rather than tcpdump.
+.LP
+Apple Ethertalk DDP packets could be dumped as easily as KIP DDP
+packets but aren't.
+Even if we were inclined to do anything to promote the use of
+Ethertalk (we aren't), LBL doesn't allow Ethertalk on any of its
+networks so we'd would have no way of testing this code.
+.LP
+A packet trace that crosses a daylight savings time change will give
+skewed time stamps (the time change is ignored).
+.LP
+Filters expressions that manipulate FDDI headers assume that all FDDI
+packets are encapsulated Ethernet packets.  This is true for IP, ARP,
+and DECNET Phase IV, but is not true for protocols such as ISO CLNS.
+Therefore, the filter may inadvertently accept certain packets that
+do not properly match the filter expression.
