[root@solaris10 ~]# /usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.12

But, when I run check_nrpe from nagios server (RHEL5) to this remote solaris 10 server, it still failed.

[root@rhel5 ~]# /usr/local/nagios/libexec/check_nrpe -H 192.168.78.104
CHECK_NRPE: Error - Could not complete SSL handshake.

Thanks a lot for your solution, would you please have me have a look into this error!

To Ton, I didn’t understand what you stated, would you please give more detail or description, sorry!

We found we also needed to apply this patch:

… to NRPE daemon so that other Nagios servers which support AES256 could still communicate over SSL to NRPE on a Solaris host.
