Try suggestion posted in the official website:
I have 2 Linux Computers & installed nagios on both systems. Also I have configured
on both linux computers.
Everything is well performed & configured as per the official NRPE installation documentation. Locally , both nagios servers are working fine. Below is the result.
/usr/local/nagios/libexec/check_nrpe -H localhost
Output :- NRPE v2.12
Same Output i am getting from another Linux PC.
But, by typing
/usr/local/nagios/libexec/./check_nrpe -H <ip add of remote linux pc>
The output is :- CHECK_NRPE: Error - Could not complete SSL handshake.
I have configured nrpe & nagios-plugins with "--enable-ssl" to avoid this "SSL" error,but the after installation, the "SSL Handshaking" error remains present.
Also ACCEPTED IPTABLES Rule to allow 5666 Port.
Here is another error if i use -n option below.
/usr/local/nagios/libexec/./check_nrpe -H <ip add of remote linux pc> -n
CHECK_NRPE: Error receiving data from daemon.
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.
Any Suggestions ??? Kindly Help me out. I am totally confused,bcoz i tried my best to sort out this problem.
Waiting for a quick & +ve reply,
