Re: Re: Snort Error - Couldn't resolve hostname HOME_NET

The problem is actually with your EXTERNAL_NET setting. It should be:
var EXTERNAL_NET !$HOME_NET

Note the dollar sign.

Here is the portion of my snort.conf where home net is defined

var HOME_NET any

# Set up the external network addresses as well.  A good start may be "any"
var EXTERNAL_NET !HOME_NET
 

i have tryed 192.168.0.1 ( the ip of the box ) also i have tryed 192.168.0.1/24
