How to install and run nettest using the fermitest scripts.  This is for
actually running the tests, which needs to be done on a seperate machine 
1) The rpms should be installed.  This places files in 3 places.
	/root/bin/
		net-test
		net-test-single
		nettest
		nettestd
	/root/test/nettest/
		nodelist
		README
	/etc/cron.hourly
		nettestd
		
2) nodelist should be edited.  There should be just one machine per line, it can
be either an ip-address, a alias, or regular node name.  Just as long as your
machine can recognize the machine with the name.  An example is below.

131.225.82.78

3) edit the net-test script so that the results get mailed to whoever you want
them mailed to.  Do this by changing the MAILTO variable.

4) edit the net-test-single script so that the correct amount of data transfer
is being tested.  Do this by editing the CHUNK and COUNT variables.  Also the
TCP_RATE should be altered to what you think is an appropriate speed for the
network.  If a nettest doesn't make it to that speed within three tries, it will
fail and put that in a mail message.

5) make sure that the fermitest-net rpm is installed on all the machines that
are going to be tested.  Make sure that the nettestd is running on them all. 
You can do this by simply runing /root/bin/nettestd. If the deamon is already
runing, it won't start again.

6) run the net-test script.  This will test all of the nodes in the nodelist
file, with a given file size that is equivilant to CHUNK x COUNT bytes.  If the
transfer speed of any of the nodes is below the TCP_RATE threshhold, you will be
mailed a summary message of all the nodes that failed with their transfer rates.
