The webserver runs as user apache, which cannot access /etc/nagios/objects by default. Chmod or chown the directory to fix it, or add user… Read more
Since WordPress 2.8, you can easily add your own links to the plugin page. This can be useful to jump right to the settings of the plugin. Example code:

To start, I setup a clean, minimal Fedora 15 installation.
After installation, we install a few more tools that we need:
yum install asterisk asterisk-fax #base

Synchronize… Read more
