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"
