Someone ( Mike ? ) seems to have accidentally commented out loghole archive code in
stop-experiment.

killed when the STOP event is received.

Also fix a couple of minor nits.

SanityCheck.py is the script for checking cross-correlation of Flexlab
runs. It works for both TCP and UDP transfers. I also changed
auto-pelab.ns and added a "-t" option to start-experiment
and stop-experiment to enable these sanity checks.

Note: I haven't figured out how to kill sudo tcpdump sessions
on PlanetLab with program agents - so, for now they have to be
killed manually after a stop-experiment. Will change this after
talking to Mike.

The cross-correlation code works correctly - I may need to tweak it
a bit in the near future for averaging times.
Also, it puts too much load on Ops and (i think) takes too much time.
I will change it so that all the correlation calculations are done on
the experimental nodes.

still generated graphs manually when needed.

Set the magic variable in auto-pelab.ns and swapin your experiment.
Logs will wind up in /proj/blahblah/exp/blahblah/logs/<node>/<name>.tcpdump
after you run stop-experiment.

I did this with the program agent and duct tape.  If it turns out that
you can already do this with the link tracing framework, then someone in
Oregon is going to whomp me upside the head with a clue-stick and he'll
never let me forget...at least til he forgets in a day or two.

to be worked out, and I need to finish the documentation, but most of
what's needed is here.

CONTENTS:

auto-pelab.ns - NS script for creating a pelab experiment. Supports
both real and fake Plab nodes.

start-experiment - perl script to start up monitors and stubs, and to
start link tracing.

stop-experiment - perl script to stop monitors and stubs, and collect
all of the files from this experiment.

TODO:
Write documentation for it - how to run it, where the logfiles go, etc.

Add hooks for the user to run their own program under test (ie iperf)

Reset condidtions on the Emulab-side LAN before an experiment starts

Get link tracing on plab (probably by starting pcapper with the
program agent)
