Nope... can't... Its SNMP and I'm querying a remote address.
The address exists, but there is no SNMP daemon on the std port.
so I query, and the remote end returns 'no port'. Since the ICMP isn't
upstream, SNMP assumes a 'no response', times out, and retries.
... All this time wasted retrying when the system already told us
there was no one there!
There has to be a better way!
