Is the agent installed on the remote host? If it is closed, lets check to see if it is running:

[root@szxdcc016 etc]# nmap -p 5666 172.20.54.194

Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2014-02-03 12:01 PST
Interesting ports on izxuap8.ivdc.kp.org (172.20.54.194):
PORT STATE SERVICE
5666/tcp open unknown

Alright, lets try to just check the version number as a test. From the remote host: From the nagios system:

[root@szxdcc016 libexec]# ./check_nrpe -H 172.20.54.194
CHECK_NRPE: Socket timeout after 10 seconds.

This what I did

please find attached document about what I tried

Can you also try running it locally as abrist suggested?

Code: Select all

/usr/local/nagios/check_nrpe -H localhost

libexec]$ ./check_nrpe -H localhost
CHECK_NRPE: Error - Could not complete SSL handshake.

Alright, we are getting closer. Was the command bleow run on the *remote host* ?

And if you try 127.0.0.1 instead of localhost?

[nagios@izxuap8 libexec]$ ./check_nrpe -H 127.0.0.1
CHECK_NRPE: Error - Could not complete SSL handshake.


Did you get a chance to look at the document... that I tried to do
