Hello, I'm trying to use the NRPE package to monitor the resources of remote computers. I'm using Fedora Core 3 as one of my clients with the following packages: nagios-plugins-nrpe-2.5.2-1.fc3.rf nagios-nrpe-2.5.2-1.fc3.rf When I test from this fedora client machine I get the following error: [root@plugins]# ./check_nrpe -H <a href="http://mydomain.org">mydomain.org</a> -c check_load NRPE: Unable to read output This is the content of the /etc/xinetd.d/nrpe file: service nrpe { flags = REUSE type = UNLISTED port = 5666 socket_type = stream wait = no user = nagios group = nagios server = /usr/sbin/nrpe server_args = -c /etc/nagios/nrpe.cfg --inetd log_on_failure += USERID disable = no only_from = x.x.x.x } The x.x.x.x isthe IP of the client machine since I'm doing testing. I will change it later to the monitor machine that runs nagios. This is the content of the /etc/nagios/nrpe.cfg ================================ pid_file=/var/run/nrpe.pid server_port=5666 nrpe_user=nagios nrpe_group=nagios dont_blame_nrpe=0 debug=1 command_timeout=60 command[check_users]=/usr/lib/nagios/plugins/check_users -w 5 -c 10 command[check_load]=/usr/lib/nagios/plugins/check_load -w 15,10,5 -c 30,25,20 command[check_disk1]=/usr/lib/nagios/plugins/check_disk -w 20 -c 10 -p /dev/hda1 command[check_disk2]=/usr/lib/nagios/plugins/check_disk -w 20 -c 10 -p /dev/hdb1 command[check_zombie_procs]=/usr/lib/nagios/plugins/check_procs -w 5 -c 10 -s Z command[check_total_procs]=/usr/lib/nagios/plugins/check_procs -w 150 -c 200 This is the content of the /var/log/secure log: May 11 10:57:48 hostname xinetd[29902]: START: nrpe pid=30509 from=x.x.x.x This is what I get when restarting the nrpe service: Shutting down Nagios NRPE daemon (nrpe): [FAILED] Starting Nagios NRPE daemon (nrpe): [ OK ] This is what the /var/log/messages log is saying when trying to restart the nrpe service: May 11 11:05:06 hostname nrpe: nrpe shutdown failed May 11 11:05:06 hostname nrpe[30554]: INFO: SSL/TLS initialized.

Also, the only plugin listed under /usr/lib/nagios/plugins/ is check_nrpe Do i need to see other plugins listed like check_load or check_disk. Or these are only switches that are used by check_nrpe? If this is a permission issue which I dont think so because when installing these packes they should take care of the permissions and ownership, can someone provide me with all the paths and permissions of each file, how they should look like? Any inputs? THANKS!
