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">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 <o:p></o:p> <div> On Fri, Aug 29, 2008 at 2:22 PM, <<a href="mailto:narendran.neelamegam@wipro.com">narendran.neelamegam@wipro.com</a>> wrote:<o:p></o:p> <div> <div> You don't need nrpe on both the monitoring and the remote sever.<o:p></o:p> <o:p></o:p> You need check_nrpe –on monitoring server and nrpe on the remote/monitored server.<o:p></o:p> <o:p></o:p> I hope you have read the relevant section of the nrpe installation document.<o:p></o:p> <o:p></o:p> Do you have additional information on the remote server such as OS etc.<o:p></o:p> <o:p></o:p> What trouble shooting steps you carried out?<o:p></o:p> <o:p></o:p> Naren<o:p></o:p> <o:p></o:p> <div style='border:none;border-top:solid windowtext 1.0pt;padding:3.0pt 0in 0in 0in; border-color:-moz-use-text-color -moz-use-text-color'> From: <a href="mailto:nagios-users-bounces@lists.sourceforge.net" target="_blank">nagios-users-bounces@lists.sourceforge.net</a> [mailto:<a href="mailto:nagios-users-bounces@lists.sourceforge.net" target="_blank">nagios-users-bounces@lists.sourceforge.net</a>] On Behalf Of Krishna Chandra Prajapati Sent: Friday, August 29, 2008 2:07 PM<o:p></o:p> <div> To: <a href="mailto:nagios-users@lists.sourceforge.net" target="_blank">nagios-users@lists.sourceforge.net</a> Subject: [Nagios-users] nrpe installation<o:p></o:p> </div> </div> <o:p></o:p> <div> I have setup nagios server its working properly.
