Hi John,

I noticed you mentioned tcpdump was working with your DAG card, but I'll
risk asking anyway:

When you compiled Snort, did you point it to your DAG-enabled pcap library
during the ./configure process?

Also, you can find a DAG DAQ over here, and works with DAG's native ERF
format I believe.
