hackers, I am running snort on 5.2.1-RELEASE, and I am getting high dropped packets rate. traffic is quiet, about 1kpps, the box runs on xeon processor, intel gigabit NICs (em driver), system load is low: CPU states: 1.9% user, 5.1% nice, 1.6% system, 4.7% interrupt, 86.8% idle Mem: 121M Active, 97M Inact, 75M Wired, 736K Cache, 60M Buf, 201M Free Swap: 512M Total, 512M Free I have tried: o both SMP and UP kernels o both SCHED_ULE and SCHED_4BSD options o libpcap libs versions 0.7 and 0.8.3 o 5.2.1-RELEASE and -current kernels o DEVICE_POLLING option o sysctl debug.bpf_bufsize set to maximum of 524288 and still having dropped packets. I am having a much lower spec box, running obsd 3.2, same snort configuration, capturing the same traffic. obsd shows constant 0 dropped packets. How would I fix that problem? _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscribe@freebsd.org"
