Hello, Has anyone managed a successful installation of Nagios using the RPMForge packages on CentOS 5.5? It looks like it should have worked, I followed the guides for Fedora and CentOS here (with appropriate path adjustments): http://nagios.sourceforge.net/docs/3_0/quickstart-fedora.html http://wiki.centos.org/HowTos/Nagios The SELinux policies look fine (I tend to ignore instructions to permanently disable SELinux, if I'm not using SELinux then there's no reason not to return to Slackware): # semodule -l | grep nagios nagios 1.1.0 # The nagios.cfg check gave the all clear: Reading configuration data... Read main config file okay... Processing object config file '/etc/nagios/objects/commands.cfg'... Processing object config file '/etc/nagios/objects/contacts.cfg'... Processing object config file '/etc/nagios/objects/timeperiods.cfg'... Processing object config file '/etc/nagios/objects/templates.cfg'...

Total Warnings: 0 Total Errors: 0 Things look okay - No serious problems were detected during the pre-flight check My adjustment of other config files is minimal, essentially just setting the email address to deliver notifications to. Yet every time I try to start the service I get this: # service nagios start nagios is stopped Configuration validation failed [FAILED] The error appears to be identical to that reported here: http://forums.meulie.net/viewtopic.php?f=61&t=6538&start=0 Like the original poster of the thread on that forum, I am able to start it with "nagios -d /etc/nagios/nagios.cfg" though various web pages continue to report an unspecified configuration error. Does anyone have any ideas? Regards, Ben -------------- next part -------------- A non-text attachment was scrubbed...
