NRPE issues

I think I had posted in the wrong category, so I’m trying this one.

I downloaded and installed NRPE using the documentation at:

nagios.sourceforge.net/docs/nrpe/NRPE.pdf

I’m installing on CentOS 5.5. I followed the installation twice down to the T. Both times I get the same results. When I go to test the NRPE install via the following command:

/usr/local/nagios/libexec/check_nrpe -H localhost

I receive the error:

CHECK_NRPE: Error - Could not complete SSL handshake.

Someone told me to grep my error log and see if any NRPE errors are listed. I found the following:

grep nrpe /var/log/messages

I double checked and made sure that both /etc/xinetd.d/nrpe and /usr/local/nagios/etc/nrpe.cfg had the correct IP address of my monitoring server.

any ideas?

I’m still having this issue. Is there anyone out there that can help?
