Nagios Support Forum

Hello Team,

We are monitoring one SUSE Linux server from Nagios XI. We have installed nrpe agent on it. We are getting below error for the services.
CHECK_NRPE: (ssl_err != 5) Error - Could not complete SSL handshake with 10.44.88.4: 1

Linuc server IP : 10.44.88.4

We alredy made changes to config file as required (dont_blame_nrpe and allowed_host) values.
Port 5666 is also open.

Could you please help us to understand why we are getting this error?

Hi,

That error result from a number of sources, if you've checked the port, dont_blame_nrpe and allowed_host settings. How did you install NRPE? Did you use the Linux Agent installer or compile from source? Let us know.

We may need to re-compile with SSL enabled. The instructions are at the bottom of the following knowledgebase article.
