I am testing a new box with ZC and an Intel ixgbe card, using CentOS 6.6,
PF_RING 6.1.0-9330, DAQ 2.0.5 and Snort 2.9.2 (I have some custom
preprocessors that don't work on newer versions), but I'm having some
issues.
I've configured and I'm able to load PF_RING and ixgbe drivers using the
init script:
*# /etc/init.d/pf_ring restart*
Stopping PF_RING module: [ OK ]
Starting PF_RING module: grep: /etc/cluster/cluster-*conf: No existe el
fichero o el directorio
[ OK ]
When I try to start more than a single instance of Snort, it fails:
*# /usr/local/snort/bin/snort -c /usr/local/snort/etc/snort.conf -i eth0
--daq pfring_zc --daq-mode passive --daq-dir /usr/local/lib/daq/ --daq-var

The /var/log/messages file gives this error for the second Snort Instance:
Jun 29 10:56:07 mybox snort[9142]: pfring_zc DAQ configured to passive.
Jun 29 10:56:07 mybox snort[9142]: FATAL ERROR: Can't initialize DAQ
pfring_zc (-1) - pfring_zc_daq_initialize: Cluster failed: Invalid argument
(error 22)
What does this "Error 22" mean? How can I solve this problem?
Thank you very much.
