Hello,

I'm trying to add a mailserver to my nagios server. So i can check when it goes down.
Every site i visited told me i had to add a host in the /etc/nagios/hosts.cfg file.

However, that path doesn't exist on my nagios server, even though Nagios was installed ...
My web interface works too on my windows (runs virtualbox). I'm using virtualbox to run my nagios server (bridged connection on virtualbox). And the mailserver is a CentOS running on virtualbox too.

Thanks for the help!
