The client is running the CentOS 5.4 operating system, and it has version 2.6 of NRPE as well as version 2.12 of the plugins installed on it. I made sure to deactivate the firewall on the system, disable the SELinux option, and also modified the /etc/services file to include port 5666 with udp and tcp. <o:p></o:p> The problem that I am having is that even though everything appears to be running properly, the requests that are sent from the Nagios server to the client are timing out, with the result being the client appearing as down. The client has the nrpe program running with the following configuration: <o:p></o:p> /usr/local/nrpe/bin/nrpe -n -c /usr/local/nrpe/etc/nrpe.cfg -d <o:p></o:p> I verified the plugins are working on the client, and also confirmed there are no other clients being reported as down. The configuration that I described is not unique to this client. This same setup is working for other clients that are monitored by the server. <o:p></o:p> Does anyone have any idea as to why this is occurring, and what I can do to correct it? Thanks. <o:p></o:p> <o:p> </o:p><PRE><o:p> </o:p></PRE><PRE><o:p> </o:p></PRE><PRE>The information in this e-mail is intended only for the person to whom it is<o:p></o:p></PRE><PRE>addressed.
