Service Check Timed Out Error

[Andy Shellam (Mailing Lists)]

Hi Andrew,

It depends on your firewall configuration on the Nagios server - but 
yes, the Nagios server will an outbound rule to allow traffic to 
destination port 5666 on your nrpe client, and also an inbound rule to 
allow traffic from source port 5666 on your nrpe client.

Your client will need an inbound rule allowing traffic to destination 
port 5666 from the Nagios server, and an outbound rule allowing traffic 
from source port 5666 to the Nagios server.

This is good for iptables anyway, FreeBSD's ipfilter is slightly 
different but the principle's the same.

Regards,

Andy
