Nagios Support Forum

Dear Team,

We installed NRPE plugin in client machine(rhel6) and modified some settings in nrpe.cfg file where we given nagios monitoring server IP in allowed_hosts option and also modified allowed_hosts in /etc/xinetd.d/nrpe .

Started the xinetd daemons and firewall is fine, but when we try to add services from the plugin, we are getting "CHECK_NRPE: Error - Could not complete SSL handshake."

i installed openssl package and i need the ssl flow in nrpe...

Please let us know and help us to resolve the issue.

I would first suggest that you walk through the possible solutions in the following document:

Did you instal openssl before you built the agent?
What method did you use to install the nrpe agent? (form our link in the XI interface, from source, or from a repository?)

Hi Team,

Thanks for ur reply... I got the solution with nrpe-2.12 version.. Firstly, i tried with nrpe-2.14 version which throws error and later i tried with nrpe-2.12 and its working fine now..

Is there any bugs with nrpe-2.14 version..??

Not as far as I am ware, though you do have to have openssl installed before building nrpe. What were the errors that you received for 2.14? The SSL-Handshake errors, or something else?

I didn't see any recent bugs:

I'm glad the issue is resolved. For the future, I would recommend using out official documentation/guides.
