Luca usually responds to questions about the PFRING DAQ.

If you are having performance issues with Snort 294 we will need more info
like CPU usage, profiling stats, etc. but it looks like you need to rule
out DAQ issues first.

Unfortunately Larry, I can't troubleshoot this for you by myself.  I try to
answer as many emails as I can, but I can't get to them all.

Cc'ing bugs at ...950... where this stuff should go.

Joel,

We downloaded the following pfring-daq-module from your site:


 PFRING External DAQ

Made popular by Luca Deri, Sourcefire’s Michael Altizer ported Luca’s
PFRING DAQ Module to the above framework.

pfring-daq-module-0.1.tar.gz<http://s3.amazonaws.com/snort-org/www/assets/162/pfring-daq-module-0.1.tar.gz>

It does not appear to be compatible with NTOP's latest release of PF_Ring
5.5.1 and daq-2.0.0 or snort-2.9.4

We want to use the pf_ring module with snort 2.9.4 but PF_Ring 5.5.1 is
giving us major packet drops?

We were using an earlier version of PF_Ring with daq-0.6.2 and
snort-2.9.3.1 and had zero packet drops running at 900meg (packet gen)?

Another fallback, is the new pfring-daq-module does not allow br0 while in
inline mode it requires: eth0:eth1

Is this problem with snort-2.9.4?

Please help us out on this please?

Thanks,

Larry
