NRPE SSL authentication

[Wim]

Hi all!

I have a problem with NRPE on one of our servers.
I compiled NRPE on one of our servers and configured my nagios to check
some services on the remote server, but I get following message as the
result of my service check:

 CHECK_NRPE: Error receiving data from daemon. 

When I look on the server where I installed NRPE on, I see in the
/var/log/messages file:

 May 25 09:08:46 odin nrpe[15635]: Error: Could not complete SSL handshake. 1


Is it because the SSL versions are not matching or am I missing something?


Thanx for any help!

Wim

My SSL version is 0.9.6b on the NRPE side and 0.9.7a on the check_nrpe

My Nagios serve runs RedHat 8.0:

My config in Nagios:

define command {
   command_name   check_nrpe

On the remote server, NRPE is configured to run under xinetd:
service nrpe
{
        disable         = no
        flags           = REUSE
        socket_type     = stream
        wait            = no
        user            = nagios
        server          = /usr/sbin/nrpe
        server_args     = -c /home/nagios/nrpe.cfg --inetd
        log_on_failure  += USERID
        only_from       = 192.168.xxx.xxx
}
