One thing is not clear to me ( from nrpe docs) Edit the /etc/xinetd.d/nrpe file and add the IP address of the monitoring server to the only_from directive. only_from = <a href="http://127.0.0.1" target="_blank">127.0.0.1</a> <nagios_ip_address>(here nagios server ip address given or Monitoring server) After executing on remote server netstat -at | grep nrpe tcp 0 0 *:nrpe *:* LISTEN (below check_nrpe is not working) Next, check to make sure the NRPE daemon is functioning properly. To do this, run the check_nrpe plugin that was installed for testing purposes. /usr/local/nagios/libexec/check_nrpe -H localhost You should get a string back that tells you what version of NRPE is installed, like this: NRPE v2.8 could not complete ssl handshake <div> On Fri, Aug 29, 2008 at 2:22 PM, <<a href="mailto:narendran.neelamegam@wipro.com" target="_blank">narendran.neelamegam@wipro.com</a>> wrote: <div> <div> You don't need nrpe on both the monitoring and the remote sever. You need check_nrpe –on monitoring server and nrpe on the remote/monitored server. I hope you have read the relevant section of the nrpe installation document. Do you have additional information on the remote server such as OS etc. What trouble shooting steps you carried out?
