I have attached nrpe file i.e /etc/init.d/nrpe

"/var/lock/subsys/nrpe" is an empty file.

root@vps [/usr/lib64/nagios/plugins]# ll /var/lock/subsys/nrpe

It looks like NRPE is already running through the xinetd daemon.

What's the output of this command?

Code: Select all

ls /etc/xinetd.d/

root@vps [/usr/lib64/nagios/plugins]# netstat -nlp | grep 5666
tcp        0      0 :::5666                     :::*                        LISTEN      28619/xinetd

The above shows that :5666 is being used by xinetd, and not the stand alone NRPE. You can find the configuration for XINETD + NRPE at /etc/xinetd.d/nrpe. This file will also reference an additional NRPE configuration file, similar to this -

Code: Select all

        server_args     = -c /usr/local/nagios/etc/nrpe.cfg --inetd

You'll want to use service xinetd restart upon making changes to your NRPE configuration.

Let us know if that works.
