CHECK_NRPE: Error – Could not complete SSL handshake

After installing NRPE on a newly build RHEL 6.3 server I saw this error message. I checked the xinetd configuration file /etc/xinet.d/nrpe and changed the following values:

disable         = no
 only_from       = 10.1.0.30

I tried to restart xinetd to propagate the changes, but……

[root@newbox ~]# service xinetd restart
 xinetd: unrecognized service

I think that xinetd is not in the basic packages anymore. I installed it manually and now it works.

[root@NAGIOS ~]# /usr/lib64/nagios/plugins/check_nrpe -H newbox
 NRPE v2.12
