[Nagiosplug-help] Host key verificationfailed.

[Carroll, Jim P [Contractor]]

Follow-up to nagios-users.  Please maintain this in the future.

You still haven't cut-and-pasted as originally requested.  However,
it *appears* that we've found the root of your problem:  You're
being prompted for the password.

What you need to do is set up a null passphrase for nagios on the
Nagios host, and install the public key on the client host(s).

I will not be giving you a tutorial on how to set up a null
passphrase and push the public key to the host(s) in question, but
I will suggest you start with "man ssh-keygen".

I'm glad to see we got to the root of the problem.
