Hi, Does anyone know if having a second application sharing a NIC with snort for packet capture seriously affects dropped packet rates, especially using Phil Wood's libpcap or pf_ring? ex. snort 2.4 + ntop snort 2.4 + agrus snort 2.4 + tcpdump You get the idea. We are currently using snort 2.4 on a Linux box with Phil Wood's libpcap with MMAP mode (might be switching to pf_ring). There is obviously issues with over all system performance when adding a second application, that's a given. My initial gut response is to say yes there will dropped packet issues, but the more I read about pf_ring/mmap the less I'm sure that my gut response is correct. Anyone have any real world knowledge on this issue? Wally ------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
