Hi Box293,
Sorry for the delay. I have attached nrpe and nrpe.cfg conf files which you asked. I hope you will give positive response to me.

I believe this is your problem:
In your /etc/xinetd.d/nrpe file:
Code: Select all
only_from = 127.0.0.1 192.168.30.38[NagiosServer]
Change it to:
Code: Select all
only_from = 127.0.0.1 192.168.30.38
Then:

Are you using TCP wrappers? Do you have anything in "/etc/hosts.allow" or/and "/etc/hosts.deny"?

If NRPE is blocking Nagios then you would want to check hosts.allow and hosts.deny on the NRPE machine.

Hi,
[root@BUGZILLABCK ~]# cat /etc/hosts.allow
#
# hosts.allow This file contains access rules which are used to
# allow or deny connections to network services that
# either use the tcp_wrappers library or that have been
# started through a tcp_wrappers-enabled xinetd.
#
# See 'man 5 hosts_options' and 'man 5 hosts_access'
# for information on rule syntax.
# See 'man tcpd' for information on tcp_wrappers
nrpe: 192.168.30.38 son1840
***************************************************************
/etc/hosts.deny file is empty

Are you using tcpd wrappers or xinetd?
What do your iptables rules look like?
