-# a wide variety of `interesting' packets from one nominated machine
-# to another, and then examine what arrived to see if there are any
-# differences.

-# on the machine you generate the test data
-# This Makefile and corresponding Tcl script
-# Tcl (as /usr/bin/tclsh)
-# OpenSSL (as `openssl' on PATH)
-# Lots of CPU ! (the generation script is rather slow)
-#
-# on the sending machine
-# tcpreplay (http://www.subterrain.net/tools/tcpreplay/,
-# or from Debian testing 3.5.2002. I used 1.0.1-1.1)
-# and root privilege to run it
-#
-# on the receiving machine
-# tcpdump for packet capture, and root privilege to run it
-# The `on-dest.sh' script that this Makefile creates
-#
-# on the analysis machine
-# tcpdump for converting trace files only, no root privilege
-# This Makefile to drive tcpdump for you, if you like
-# diff to look at the output
-#
-# It will be much better if the machines you are using do not have any
-# other traffic. If they do the tests may disrupt it, and it'll get
-# in the way of your analysis too.
-#
-#
-# WHAT TO DO
-#
-# 1. Generate the test data.
-# * Edit this Makefile.
-# You /must/ change SOURCE and DEST; they must be IPv4 addresses.
-# You may also change PARTS, PERPART or MTU if you like.
-# * Say `make -j2 generate'. This will generate the test data sets.
-# This will take a while. Vary the -j for your system.
-# * Copy send-*.pcap and on-dest.sh to the sending machine.
-#
-# 2. Run one of the tests
-# * Pick a PART number, say 1, to start with.
-# * On the receiving machine, say, as root,
-# ./on-dest.sh PART
-# and leave it running.
-# * On the sending machine, say, as root,
-# tcpreplay -m 1 <send-PART.pcap
-# The -m 1 option makes tcpreplay send the packets at one a
-# second (they are generated as if they were captured at one
-# a second); this avoids flooding the network, which causes
-# congestion, packet loss and maybe other randomness.
-# This will take (by default) 100 seconds.
-
-#
-#
-#
-# FILES INVOLVED
-# Those made by `make generate':
-# send-*.pcap `pcap' format raw test data files
-# (feed this to tcpreplay -m 1)
-# send-*.log tcpdump's interpretation of the test data
-# with line numbers added
-# send-*.why The generator's explanations (ha ha) of
-# what the test data is
-# on-dest.sh Script for running tcpdump on the destination
-#
-# Those supposedly captured at the destination
-# recv-*.pcap `pcap' format raw received packets
-#
-# Those made during the analysis:
-# recv-*.log tcpdump's interpretation of the received packets
-# recv-*.diff difference between send-*.log and recv-*.log
-# all.diff all the .diff's concatenated in one easy file
-#
-#
-# On the receiving machine,
-#
-#
-# on the
-# Run this makefile anywhere to generate the test data sets
