Run a script each time the network interface change

[tquille]

Hi,

I would like excecute a bash script each time the network interface change his state to UP.

For this, i would like use the command "post-up" in the file "/etc/network/interfaces", but this file is empty

Can you help me to launch a script when i up my network interface ?

Best regards,

Chris

You have the if-pre-up and the if-up directories. if-up is run after the interface comes up, so that's the one you want. Just put your script, or a symlink to it, in this directory and it will be run after the interface comes up every time. (I don't know the order that these scripts are run; probably alphabetical ascending, but google it if it matters for your application.)

Thank you, it's works.
