Excuse me for reviving this thread. I've been using Snort's DAQ module variable no-kernel-filters for a long time, but recently switched to pfring_zc and got this error:
FATAL ERROR: Can't initialize DAQ pfring_zc (-1) - pfring_zc_daq_initialize: unsupported variable(no-kernel-filters=1)#012 Why isn't this variable present on the ZC driver ? Am I missing something ? Thanks, Jose Vila.
