How to

Dead simple.

Open up the file /etc/network/interfaces. It will show you something like:

# This file describes the network interfaces avilable on your system 
# and how to activate them. For more information, see interfaces(5).

source etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

and add at the end of the file, this line:

pre-up ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx

This will spoof your mac address to xx:xx:xx:xx:xx:xx every time your computer boots up.

The better how to

But the above solution sets your mac address to the same value every time.So you might wanna use macchanger:

pre-up macchanger -r eth0 
pre-up macchanger -r wlan0

Adding these lines to /etc/network/interfaces file will set the mac addresses to random values every time your computer wakes up.
