AW: [Nagiosplug-help] check_by_ssh Plugin

[Schindewolf, Stefan, Infraserv-Hoechst/DE]

Hello.

First thanks a lot.

I can assure you that I already cheched the credentials on the
authorized_keys and the public key itself. To test a plugin by ssh I "su -
nagios" and then enter the full command line. The Plugin says state "OK
<message>". Everything seems to be in order.

But when I look into the WebGUI I read "Warning Hostkey verification
failed", even when I force a new check.

The problem seems to be with nagios daemon itself. Does it use a buffer or
something which is not cleared proberly?

Best regards
Stefan

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.
