How to protect NRPE traffic with certificates

Post by sheen.lim »

In a previous post i was able to communicate with my windows server via nsclient++ with insecure mode.

However, I really want to try communicate with the nagios server using certificates.

It seems the documentation regarding on nsclient++ and nagios nrpe using certificates are very rare if not outdated.

so First, How can I create certificate in the nagios server using openssl using the libressl library.?
second, How can I tell check_nrpe to use the certificate compiled with libressl?
third, how can I publish that same certificate on the widnows host?
