Hello all...

Apologies for this being a bit of a cross mailing-list problem - if
the trouble doesn't lie with PF_RING then I'll post to snort-users.

I've been following (linked from the ntop blog):
http://www.metaflows.com/technology/pf-ring/

However I built DAQ-0.6.1 and PF_RING from SVN.

When I try and invoke snort:

snort -A console -u snort -g snort -c /etc/snort/snort.conf --daq
pfring -i eth0

I see (edited):

pfring DAQ configured to passive.
Acquiring network traffic from "eth0".
