I installed snort 2.2.0 on Mac OS X 10.3.6 together with ACID 0.9.6b23. Everything went fine. When I start snort:

sudo snort -dvi -c /etc/snort/snort.conf

I get the following:

Running in IDS mode

Nothing gets reported. I have configured snort.conf like this:

var HOME_NET any
and
var EXTERNAL_NET any
and
output database: alert, mysql, user=root password=<mypassword> dbname=snort host=localhost

Can anyone help?

Thanks,
Allan
