actually, i don't think that is supposed to be the case. since it's a service
being checked *via* ssh, the state of the service can not be known, therefore
it is "unknown". a proper nagios config should have some kind of host check
(and/or service dependencies on check_by_ssh <-> check_ssh) that detects
when the host is down, which will return critical and disable the checks of
the service in question.
