[Nagiosplug-help] check_by_ssh does not seem to honour StrictHostKeyChecking

Hello out there,

when monitoring service-bound IPs using check_by_ssh I encounter the problem that several servers might answer which have differing ssh server keys. 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.

Any suggestions?
