After what seemed like days of messing with permissions, SELinux was the problem. To solve the dreaded Could not stat() command file ‘/usr/local/nagios/var/rw/nagios.cmd’!” error, when trying to reschedule a test or acknowledge an alert, a simple setenforce 0 was the solution. Though, permissions do also have to be correct. chown nagios.nagcmd /usr/local/nagios/var/rw chmod g+rwx /usr/local/nagios/var/rw chmod g+s /usr/local/nagios/var/rw

Using a script to count login activities in a KF log file. I wanted to effectively go through all the *.log?? files, ignoring zipped files. Finally settled on: my $logpath=”/var/log/kforum”; chdir($logpath) or die “$!”; @files = glob “*.log *.log.[0-9] *.log.[0-9][0-9]”;

The first thing I wanted to do was deal with the web server. I didn’t want apache serving any pages other than nagios. I decided to redirect everything to techmentor.com. To do this I has to allow overrides int the main conf file: <Directory “/var/www/html”>     Options Indexes FollowSymLinks    AllowOverride All    Order allow,deny    Allow from all </Directory> Then in /var/www/html I created the following .htaccess file: RewriteEngine on AddType text/cache-manifest manifest RewriteCond %{HTTP_HOST} ^backwater\.techmentor\.com$ RewriteRule ^/?$...
