[Nagiosplug-help] Check_SNMP Failure

I found the problem.  My primary DNS server did not have the lookups in its
host table but the secondary did.  For some reason getting rid of the first
and letting the secondary become primary solved the problem.  Must have been
a timeout issue or something.

In these cases, I run a snmp-browser from the same machine as nagios is
running from, to verify the problem.

I personally use mbrowse (www.mbrowse.org), that needs the x11-client
libraries being installed.

I use a FreeBSD box here to monitor some cyclades console devices and a
couple of 2003 Servers, had no hassle with them, except with failures on
the software management agents under 2003 (misconfig on one server
