I wouldnt let any other Check define if a Host is up or down, let
alone Availability of ssh.
I usually (if check_host_alive is no option) simply use /bin/true for
the Hostcheck - Nagios simply sees the Host as always up and i
will find any Service checked.
One might write a check_raw Plugin which uses various tricks to find out
if a Host is up, i.e. (for UDP) sending a Packet and expecting
ICMP_PORT_UNREACH within 5 seconds. That would most probably requiring
the Binary setuid root.
What do others think?
