Someone else with this problem! Its doing this because you're logging connection attempts to ports that aren't listening. I don't know why the attempts happens. I get hundreds of these a day: Connection attempt to UDP 127.0.0.1:50675 from 127.0.0.1:53 Connection attempt to UDP 127.0.0.1:54731 from 127.0.0.1:53 Connection attempt to UDP 127.0.0.1:54730 from 127.0.0.1:53 Connection attempt to UDP 127.0.0.1:54807 from 127.0.0.1:53 Strangely enough, mine are all to -> from locahost. Possibly because this box has a real address? net.inet.udp.log_in_vain: 1 Whomever solves this one is my hero for life ;) I think its a feature. -Charlie
