How to display a message each time eth1 is enabled?

Question

How can I display a message like:

eth1 interface has been enabled

each time when eth1 is enabled?

Let me know if my question make sense.

You don't get notifications when your network is enabled or disabled? All modern operating systems are doing this. Why you should let reinvent the wheel? — Radu Rădeanu, Aug 22 '13 at 15:02
@RaduRădeanu There doesn't have to be anything wrong with it good grief. If he wants to change it, what is that to you? — Seth, Aug 23 '13 at 15:15

After some searches, I found a way how you can do it:

First, disable the usual notification from Network Manager. How? Your answer is here:
- How to disable notification from network-manager
Run a script to notify you every time internet connects. How? Here is your answer:
- How to run a script, depending on internet connection
How you can get notified from a script? Again, there are answers on Stack Exchange in this sense:
- Is there a way to show notification from bash script in Ubuntu?
- Sound notification in Ubuntu terminal

You can add a shell script into /etc/NetworkManager/dispatcher.d that you might name 99-notification. Be sure to mark it executable with chmod +x 99-notification.

In that script, you will need to do something with the input to script, the interface name and the action.

#/bin/bash

if [[ "$1" = eth1 ]] && [[ "$2" = up ]]
then
    DISPLAY=:0.0 kdialog --passivepopup "eth1 is enabled" 3
fi

I have not tested this, but I think it will work, at least with KDE. For Unity/Gnome, you might have to exchange kdialog with zenity.
