<div class="gmail_quote">Hi, All, I've got some issues when tried to install NRPE_plugin (or addon) on a ngios monitor host. The server on which I wanted to get NRPE_plugin run has been installed and configured with Nagios 3.2.1 and Centreon 2.1.8, and both of them ran okay. BTW, the OS of the server is Ubuntu 8.04 LTS. I followed the procedures described in the NRPE.pdf, and what I had done included: cd /usr/local/src wget package of nrpe-2.12 untar cd nrpe-2.12 ./configure make all make install-plugin Then, cp /usr/local/src/nrpe-2.12/src/check_nrpe.c /usr/local/nagios/libexec/check_nrpe chmod a+x check_nrpe When I tried to execute /usr/local/nagios/libexec/check_nrpe -H <remote server running nrpe daemon>, I got the followed messages: line 1: /bin: is a directory line 2: centreon.conf: command not found line 3: centreon.conf: command not found line 4: syntax error near unexpected token `(' line 4: ` * Copyright (c) 1999-2008 Ethan Galstad (<a href="mailto:nagios@nagios.org" target="_blank">nagios@nagios.org</a>)' Actually, I even couldn't find the stuffs like '/bin' or 'centreon.conf' in the check_nrpe.c file, so don't know where these errors came from. This was the first time I tried to install and configure Nagios and the frontend, and this error really confused me. Could anybody give me some help with that? I really appreciate it if anyone have time to read this mail and provide me some advices. Regards, Collin </div>
