init script bug about nagioscore HOT 1 CLOSED

This error message is from cmd.cgi, not Core. Did the full message look like this?

As the message says the permissions are likely incorrect. The Fedora Quickstart Guide covers this (it needs to be updated, but it's basically correct if you substitute the right version numbers). Pay attention to sections: 1) Create Account Information; 3) Compile and Install Nagios; and 8) Modify SELinux Settings.

Modifying the init script to make nagios.cmd world readable and writable is not good because any user can then add commands or garbage input, or remove commands by reading from the command pipe.

There are a few threads on this and other similar permissions issues on the Nagios Support Forums. These in particular may be helpful:

If you are unable get this sorted from these resources, start a new thread on the Nagios Core Support Forum. This will get more eyeballs on your problem (we have dedicated support techs and some really helpful community members), and is the preferred forum for installation and configuration issues.
