Suggest starting with double checking your configuration. Did you bridge the interfaces? On Tue, May 21, 2013 at 5:12 AM, Oleg Gvozdev <jktu17 () gmail com> wrote:
I have a problem with IPS mode. I wonder how afpacket can drop/block traffic. 1.I saw daq-1.1.1/xxx/daq_afpacket.c : daq_acquire() use raw socket and kernel rx_ring to receive ethernet data. 2. on each packet snort callback is called and if verdict after callback is PASS, then daq use sento() to send packet on interface ; else: if verdict is DROP - then nothing is sendig. 3.I comment sendto call in daq so any traffic will not be sent, but ICMP pings for example go through snort as if snort was disabled. So - I can not see how dropping can be done by daq: using only raw sockets i think is not enough..? ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
