Re: PF_RING and DNA with Snort

[Tim Covel <tcovel () metaflows com>]

It looks like in newer versions of PF_RING you have to specify multiple 
clusterid values when using inline mode:

pfring-daq-module/README.1st suggests: "--daq-var clusterid=10,11" in 
the IPS example.

and also explains the clusterid var as:
"--daq-var clusterid=<comma separated id list>
where an id is a number (i.e. the clusterId), one for each interface."

It also looks like you are not currently using DNA interfaces, you need 
to make sure to load the correct driver (PF_RING/drivers/DNA/<driver 
version>) and start snort using the DNA interfaces the driver creates if 
you want to use DNA.
