[Nagiosplug-help] check_by_ssh Plugin

[Sean Knox]

Remember that nagios will attempt to ssh into the other machine as user 
"nagios" by default. I would guess your manual  check passed as you were 
using *your* key as user stefan (sic), not as nagios. Try su'ing to the 
nagios user and try your test again; if it fails, you will then know 
that you'll have to readdress your ssh setup.

Also verify that the ~nagios/.ssh/authorized_hosts1/2 file(s) contain 
the correct public key.
