Re: PF_RING and DAQ compile (0.6.2, and 2.0.0)
From: Avery Rozar <Avery.Rozar () i-techsupport com>

In the /etc/sysconfig/snort file. To my knowledge the DAQ can not use a
bridge interface, just binding the two together. That’s how afpacket is
working for me anyway. It just errors out when trying to use pfring.

#### General Configuration
# Inline? Set to 1 if yes: Else, set to 0
QUEUE=1

# What interface should snort listen on?  [Pick only 1 of the next 3!]
# This is -i {interface} on the command line
# This is the snort.conf config interface: {interface} directive
INTERFACE=eth2:eth3

The original error was on a KVM VM. I was using eth1:eth2 and got that
error. I moved it to the host, and am now using eth2:eth3 and got the
same
error but it did state "eth2". I just copied the original error for the
post, that¹s why eth1 is in it. No matter what interface I use, I get
the
same error.

ahhh... you are bridging eth2 and eth3?? doesn't that create another
interface? 
br1 or such? where and how are you specifying this eth2:eth3??

Thank you for your answer Tim, I can only assume that you answered my
first question on the Meteflows group. I'm getting an error "FATAL
ERROR:
Can't start DAQ (-1) - pfring_open(): unable to open device 'eth1'.
Please

eth1...

use -i<device>!" when I try to start snort using pfring. I thought
maybe
is was due to the DAQ compile error. I moved snort off the VM, and on
the
physical host, and disabled selinux. I still get the same error. Would
it
be due to the default bnx2 driver, or pfring license issue? Any help
is
greatly appreciated.


ethtool -i eth2

eth2...  not the same as above... why? ;)
