Just going out on a limb here (for fun); what if the box was in Siberia? 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").
