That's true, but OTOH there are many interesting network conditions like excessive packet loss that we don't shout about. The stats are quietly gathered and can be examined with netstat. If a system is properly monitored then such counters are graphed and can trigger alarms. If the system just misbehaves then an administrator can use netstat for inspection. Spamming logs in the case of e.g. DDoS attack is not very helpful, IMO. -- Andriy Gapon _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
