It would try to renegotiate in 24 hours if it didn't come back to the point where you could remove the line. Heh ;D Nah, I just use cron because I've had bad luck in the past with attempts to renegotiate the network from a process that itself is spawned via a network process. That includes running things with nohup -- they still seem to die. Cron has always done me right though (but I've never tried using "at"). -- Devin _____________ The information contained in this message is proprietary and/or confidential.
