Re: Snort 2.9, RHEL 5 and afpacket DAQ

My be would be that your kernel does not have built-in support for
mmapped socket_io (which is built-in since 2.6.34ishh) if i remember..

What is your kernel version?

Hi,

I am playing around with Snort 2.9.0 on RHEL 5. Using the DAQ libraries
with libpcap works fine. But the afpacket daq module always bails on
loading:

# snort --daq afpacket
Running in packet dump mode

       --== Initializing Snort ==--
Initializing Output Plugins!
afpacket DAQ configured to passive.
Acquiring network traffic from "eth0".

It works fine on Fedora 13. I have searched the mailing lists but have
not found any clue. Does the kernel on RHEL 5 (2.6.18) not provide the
necessary interface?

It would be fine if stated in the README or FAQ but I have not found
anything.

Any hints, clues, advices?

Kind regards,

Ralf
