CHECK_NRPE: (ssl_err != 5) Error - Could not complete SSL ha

[kalyanpabolu]

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.
