How to run a script when disconnecting a dialup connection

["Chris R. Martin" <bluerider@bigfoot.com>]

I know that ip-up and ip-down are run by pppd when the link is brought up
or down respectively. However, ip-down is run AFTER the link is brought
down. What I'd like to do is run a script or two BEFORE the link actually
goes down.

Using Debian 2.0. Any hints?

Thanks,
Chris
