Hi Erek, looks you are in the correct track. Running Snort with "-v" and 
without the Daemon option shows it snorting ok. However no new 
entries/alerts are being generated in /var/log/alert
I forgot to mention, I'm newbie to Snort. How do I check the Acid Sensor 
and if Snort rules are in fact activated?

Tks a lot, Erek.
