If you have not built libpcap, and your system does not have libpcap
installed, install libpcap first. Your system might provide a version
of libpcap that can be installed; if so, to compile tcpdump you might
need to install a "developer" version of libpcap as well as the
"run-time" version. You can also install tcpdump.org's version of
libpcap; 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 generally available GNU C compiler (GCC).
After libpcap has been built (either install it with "make install" or
make sure both the libpcap and tcpdump source trees are in the same
directory), 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". This will install
tcpdump and the manual entry. Any user will be able to use tcpdump to
read saved captures. Whether a user will be able to capture traffic
depends on the OS and the configuration of the system; see the tcpdump
man page for details. DO NOT give untrusted users the ability to
capture traffic. If a user can capture traffic, he or she could use
utilities such as tcpdump to capture any traffic on your net, including
passwords.
Note that most systems ship tcpdump, but usually an older version.
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.
Please see "PLATFORMS" for notes about tested platforms.

formerly from Lawrence Berkeley National Laboratory
Network Research Group <tcpdump@ee.lbl.gov>
ftp://ftp.ee.lbl.gov/old/tcpdump.tar.Z (3.4)
This directory contains source code for tcpdump, a tool for network
monitoring and data acquisition. This software was originally
developed by the Network Research Group at the Lawrence Berkeley
National Laboratory. The original distribution is available via
anonymous ftp to `ftp.ee.lbl.gov`, in `tcpdump.tar.Z`. More recent
development is performed at tcpdump.org, http://www.tcpdump.org/
Tcpdump uses libpcap, a system-independent interface for user-level
packet capture. Before building tcpdump, you must first retrieve and
build libpcap, also originally from LBL and now being maintained by
tcpdump.org; see http://www.tcpdump.org/ .
Once libpcap is built (either install it or make sure it's in
`../libpcap`), you can build tcpdump using the procedure in the `INSTALL.txt`
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.sigcomm.org/ITA/
Another tool that tcpdump users might find useful is tcpslice:
* https://github.com/the-tcpdump-group/tcpslice
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, etc. should be sent
to the address "tcpdump-workers@lists.tcpdump.org". Bugs, support
requests, and feature requests may also be submitted on the GitHub issue
tracker for tcpdump at:
* https://github.com/the-tcpdump-group/tcpdump/issues
Source code contributions, etc. should be sent to the email address
above or submitted by forking the branch on GitHub at:
* http://github.com/the-tcpdump-group/tcpdump/tree/master
and issuing a pull request.
Current versions can be found at www.tcpdump.org.

-------------------------------------
```
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".

To build tcpdump under Windows, you need:
- version 6 (or higher) of Microsoft Visual Studio or the Cygnus gnu
C compiler.
- The November 2001 (or later) edition of Microsoft Platform
Software Development Kit (SDK), that contains some necessary includes
for IPv6 support. You can download it from http://www.microsoft.com/sdk
- the WinPcap source code, that includes libpcap for win32. Download it
from http://winpcap.polito.it or download libpcap sources from
http://www.tcpdump.org and follow the instructions in the README.Win32
file.
First, extract tcpdump and WinPcap in the same folder, and build WinPcap.
The Visual Studio project and the cygwin makefile are in the Win32\prj
folder.
From Visual Studio, open windump.dsw and build the program. The release
version of the WinDump.exe executable file will be created in the
windump\win32\prj\release directory . The debug version will be generated
in windump\win32\prj\debug.
From cygnus, go to windump\win32\prj\ and type "make". WinDump.exe will be
created in the same directory.

* the GCC manual doesn't appear to explicitly say that
* __attribute__((packed)) causes the compiler to generate unaligned-safe

*
* We do this in case the compiler can generate code using those
* instructions to do an unaligned load and pass stuff to "ntohs()" or

* to define unaligned_uint16_t as a 16-bit unaligned data type.
* This could be presumably used, in sufficiently recent versions of
* the compiler, with macros similar to those below. This would be
* useful only if that compiler could generate better code for PA-RISC
* or Itanium than would be generated by a bunch of shifts-and-ORs.
*
* DEC C, indicated by __DECC being defined, has, at least on Alpha,
* an __unaligned qualifier that can be applied to pointers to get the

* field from the sum of all the data in the packet, and then
* computing the negative of that value.
*
* "sum" is the value of the checksum field, and "computed_sum"
* is the negative of the sum of all the data in the packets,
* so that's -(-computed_sum - sum), or (sum + computed_sum).
*
* All the arithmetic in question is one's complement, so the
* addition must include an end-around carry; we do this by
* doing the arithmetic in 32 bits (with no sign-extension),
* and then adding the upper 16 bits of the sum, which contain
* the carry, to the lower 16 bits of the sum, and then do it
* again in case *that* sum produced a carry.
*
* As RFC 1071 notes, the checksum can be computed without
* byte-swapping the 16-bit words; summing 16-bit words
* on a big-endian machine gives a big-endian checksum, which
* can be directly stuffed into the big-endian checksum fields
* in protocol headers, and summing words on a little-endian
* machine gives a little-endian checksum, which must be
* byte-swapped before being stuffed into a big-endian checksum
* field.
*
* "computed_sum" is a network-byte-order value, so we must put
* it in host byte order before subtracting it from the
* host-byte-order value from the header; the adjusted checksum
* will be in host byte order, which is what we'll return.

* o Type 1 stands for PadN sub-TLV with the same encoding as the PadN TLV.
* o Type 2 stands for Diversity sub-TLV, which propagates diversity routing
* data. Its body is a variable-length sequence of 8-bit unsigned integers,
* each representing per-hop number of interferring radio channel for the
* prefix. Channel 0 is invalid and must not be used in the sub-TLV, channel

* o Type 3 stands for Timestamp sub-TLV, used to compute RTT between
* neighbours. In the case of a Hello TLV, the body stores a 32-bits
* timestamp, while in the case of a IHU TLV, two 32-bits timestamps are
* stored.

* Diversity sub-TLV is not the same as a Diversity sub-TLV with an empty body.
* The former would mean a lack of any claims about the interference, and the
