find out if the ping program on RedHat 5.9 has an option to show
network addresses as numbers.  Then pass this option to ping using
mrtg-ping-probe's option '-o'.  Also, use the IP address as the target
and not the host name.

On Solaris, ping has the option '-n' to show network addresses as
numbers, so I can make sure that we don't depend on the DNS server:

	mrtg-ping-probe -o -n

Hope this helps....
