check_nrpe - Could not complete SSL handshake.

[Guy Waugh]

Hi there,

A couple of thoughts...

Have you put the NRPE service into /etc/services, like so:
[root at remote-server /]# grep nrpe /etc/services
nrpe            5666/tcp                        # NRPE for Nagios

Also, do you allow connections on the NRPE port to the remote server 
from the Nagios server in /etc/hosts.allow, like so:
[root at remote-server /]# grep nrpe /etc/hosts.allow
nrpe:           10.0.0.1
(where 10.0.0.1 is the Nagios host)

I run NRPE out of xinetd - this is a facsimile of my /etc/xinetd.d/nrpe 
file:

service nrpe
{
         flags                   = REUSE
         socket_type             = stream
         wait                    = no
         user                    = nagios
         log_on_success          += USERID
         log_on_failure          += USERID
         server                  = /usr/local/sbin/nrpe
         server_args             = -c /etc/nrpe.cfg --inetd
         disable                 = no
         only_from               = 10.0.0.1
}

HTH,
Guy.
