- 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).

- 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: INSTALL,v 1.25 96/07/21 04:02:01 leres 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 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 3.2.1
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 libcap, 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://town.hall.org/Archives/pub/ITA/
Problems, bugs, questions, desirable enhancements, source code
contributions, etc., should be sent to the email address

-------------------------------------
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".

* FDDI support for tcpdump, by Jeffrey Mogul [DECWRL], June 1992
*
* Based in part on code by Van Jacobson, which bears this note:
*
* 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...
