[TuT] [Ubuntu/BT5] Randomize MAC Address on start up.

1) load macchanger from the repositories

This is a simple, well documented, self-explanatory program that requires manual running - we want to automate it.

2) write a small script:

#!/bin/sh
# run macchanger at boot
    
    sudo service network-manager stop

    sudo macchanger -A eth1
    sudo macchanger -A wlan1

    sudo service network-manager start

exit 0

Note the wlan / eth codes might need tweaking

3) Save this as macrotator in /etc/init.d/ and make it executable

4) Register the script by running:

sudo update-c.d macrotator defaults

5) Reboot

::Confirmed on Ubuntu 12.10 & BackTrack 5 R3::
