Hmm, but how should a userland application get access to data which is 
dropped at the kernel level already?

When I check the output of 'snort -dev' with iptables active compared to 
iptables turned off it shows a very big difference. With iptables on I can 
comfortably read the output, with iptables off the data just rushes by.

How do you manage to get snort to read the unfiltered traffic on the 
interface?
