Snort and PF_RING DAQ

Hello all

I've been testing a recent Snort and PF_RING (5.4.x) from SVN
and the DAQ bundled with that.

Obviously the DAQ is slightly 'non-standard' as it is not bundled with
the usual DAQ distribution.

During test I notice that the DAQ cannot acquire traffic unless Snort
is running as root - something I've avoided doing with Snort by
specifying a specific user/group with -u and -g for many years.

Is this privilege problem a fault of PF_RING, or a problem with Snort
not dropping privileges at the right point?

Thanks.
