FYI, the campus network administrators have had to block pings from off campus
due to some denial-of-service attacks in May.  Since the Mt Graham network 
is technically "off campus", pings from/to there are mainly blocked.  So if 
you're wondering if the network or a particular machine is down, ping probably
won't tell you much.  But since I have scripts that use ping to document
network outages, I got the administrators to make exceptions for those machines
that run the scripts (gaffel and frankenheim).  Frankenheim is allowed to ping
gaffel and gaffel is allowed to ping any machine on Mt Graham.  If you want to
see the latest ping results from these scripts, do 

	tail /net/gaffel/gdisk/peters/netcheck.stat
	tail /net/frankenheim/dka100/peters/netcheck.stat

The beginning of these files (which are purged monthly), give an explanation 
and column headings.  To see this, do "head" instead of "tail".
