Install and it worked wonderfully. I want to Monitor 1 remote server's
SMTP. I have been experimenting with 2 configuration files (Pasted at
the end for reference) without much luck. With config #1, I receive
messages telling me the host is down constantly (I assume this is
because it blocks ICMP ping requests) I then found a sample on one of
the forums which I tried to implement; but I recieve no messages and
Nagios still says host is down in the browser. Basically I'd like to
show the host as up and recieve messages when SMTP is unavailable. Does
anyone have any samples (Pref with comments) that I can experiment with?
I am particually interested in monitoring publically available services.

There is no substitute for reading the manual. (cover to cover)

You can use whatever check you like to run as a check on the host. So if
you can not ping the default check is pointless. If SMTP is the only
service open then use check_smtp as host check.
