Version: <= 2.12
The SSL option of the NRPE plugin and server does not perform any kind of authentication. It has no certificates, only a DH key, which is generated at compile time.
This means that the nrpe key is identical to all debian systems, but subject to change every time the package maintainer uses the ./configure script.
My patch adds full SSL certificate verification to nrpe. Note that this breaks backwards commandline compatibility, because the previous mode was insecure. This means that the check_nrpe rules must be edited in the nagios configuration as well.
