I am adding a CentOS Asterisk server to be monitored and everything goes fine until I edit the /usr/local/nagios/etc/nrpe.cfg file. Once I make any changes to that file I start to get "ERROR: could not complete SSL handshake" errors. The only way I have found to get passed this is to recompile/install nrpe. I need to edit the nrpe.cfg file to change the check_hda1 command to check_sda1 and look for dev/sda1 for check_disk.
If you need more information just ask, any help is much appreciated, thanks in advance.
