Event triggers

Triggers launching external scripts when an uplink goes up or down, for example to change some parameters in a mail server.

DUDE if i could restart a service when an interface came on line....i would.. love it so much..more than i already do (didnt think that was possible) but im talking possible marriage here!

It would be particularly useful, to me, to be able to restart networking or pppd or ifdown/ifup my wlan connection when a specific interface stops routing.

Sometimes those connections get into a state where they won't recover until I manually intervene, and I'd prefer to script that.
