Re: Using afpacket in IDS mode - HELP PLEASE

I just wanted to ask this question again. Is there any reason not to
use afpacket when running in passive mode rather than standard
libpcap?

Thank you

Hello,

I was reviewing my sensor configurations and was wondering about the
use of afpacket in IDS mode.  Is there any reason not to use it when
monitoring passively opposed to libpcap?

I'm testing it in this configuration and am seeing this in my logs.
My daq_var buffer_size_mb=2048:

S5: Session exceeded configured max bytes to queue 1048576 using
1049220 bytes (client queue)

Is this also happening in pcap mode but the the logging isn't as verbose?

Thank you
