If there is a network problem, the connections will terminate from a data timeout due to the syslog messages being transmitted over the connection long before it would terminate from a keepalive timeout. I'm not saying that a person fitting the profile doesn't exist, I'm saying that there are so few of these people that the benefits outway the issues by several orders of magnitude. I can only repeat: Turn them on and see if they effect you. You will almost certainly find that they do not effect you. Ask your friend to turn them on and see if they effect him. If he's tailing syslog in those windows they won't effect him. -Matt :detlev$ finger nemo@[deleted] :[[deleted]] :Login: nemo Name: Joel N.
