You can hook arbitrary commands to be performed when an interface comes up (or down, or both) by adding lines to /etc/network/interfaces. Check out the interfaces man page for examples. You could also create a dhclient-exit-hooks script in /etc/dhcp3. That's a bit more consistent across distros, but less flexible since it will apply to any interface configured via DHCP. -- Todd Pytel ---------------------------------------- Signature attached PGP Key ID 77B1C00C
