This way the service check fails whenever the answering server changes. A (far from perfect) solution to this would be to set StrictHostKeyChecking to no for the relevant IP. check_by_ssh however does not seem to honour this setting (not 1.4.15 and below) -- as long as I don't remove the offending key from known_hosts the plugin will time out.

Good idea -- with a tiny drawback: This requires a new check command for service IP checks, and changing the Nagios configuration this way is much more cumbersome than setting  StrictHostKeyChecking=no in .ssh/config for the IPs in question.

Well... one must not be too lazy, right?

Thanks a lot
