check_nrpe = failed to establish secure connection

[lejeczek]

hi everybody
from a linux nagios 3.5.1 I'm trying to connect to nsclient 0.4.1.90 and get this:

failed to establish secure connection: unknown protocol

would you say it's compatibility problem between the two?
Or maybe I'm missing some config/settings?
many thanks

This should work fine between the two, but you need to enable the NRPE in the nsclient++ configuration, which is not enabled by default, as well as add your nagios server as an allowed host.

If it is enabled, can you give the check_nrpe command you are executing?

[lejeczek]

yes, apologies for I was careless for a moment and did not see I used -n to check_nrpe
thanks.

No worries. We'll go ahead and close this thread. Thanks.
