about NetworkManager and /sbin/ifup-local

[Gabriel Ramirez]

Hi,

I need to run a script when the eth0 interface goes active, under 
service network is active this work fine using /sbin/ifup-local in my 
desktop machine

but in my netbook running NetworkManager the script /sbin/ifup-local 
don't work, so where can define/put a  script so NetworkManager runs it 
when one network interfece goes active?

or where  can define the classes and qdiscs of a network device under 
networkmanager, it seems to define some by default by the output of:

tc -s qdisc ls dev eth0
tc -s class ls dev eth0
