Might be lots of things. From someone else using your IP to a bad renewal of a DHCP lease. Try turning on the 'mark' option in syslogd so that you see a regular pulse in the logs. Then run a ping into the box from somewhere else. After an episode of the problem compare the logs. Maybe that will help isolate the problem. chris -- Chris Fedde 303 773 9134 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
