If you have plenty of cpu and memory I am assuming you are not page faulting, in which case you might just need to use the mmap version of libpcap. It uses less cpu than the standard pcap, but also has much less packet latency during sniffing so it does not drop as much. -----Original Message----- From: snort-users-admin () lists sourceforge net [mailto:snort-users-admin () lists sourceforge net] On Behalf Of Larry Wichman Sent: Tuesday, September 28, 2004 10:14 AM To: snort-users () lists sourceforge net Subject: [Snort-users] packet loss In the course of my testing of Snort I have averaged about 40% packet loss. I am running Snort on Fedora. The segment I am monitoring is 100 mb and is very busy. Does anyone have any recommendations for tuning Snort to not drop so many packets? Is there any recommendations for hardware? The CPU is running at about 40% and the memory looks fine. ~Larry _____ Do you Yahoo!?
