check_ping problem

[Robert Nelson]

Actually, I changed the DNS entries to something that would work, since
my priority was to get the device monitored, THEN to figure out why
Nagios didn't like it :) The new hostname is
tap-5300h.wachovia2.nc.windchannel.com

I was curious if that's an actual restriction in DNS, or a "guideline",
that domains can't start with numerals. Normal ping and nslookup don't
puke on it, though.
