Yes, I will continue using my current protocol list that I built
from /etc/services, it seems to catch most of the  tcp/udp ports. I just
get sick of updating it with the new filesharing protocol of the day. I
just installed 3.1 recently, I'm also trying to get the host
fingerprinting working, I have installed ettercap, is there something I
need to do to turn it on? I can't find any flags for it.
