Step by step How to Change MAC Address on Kali Linux:
1. Open your terminal, and type ifconfig | grep HWaddr you will see your original MAC address, mine was 08:00:27:b2:4d:4b
2. To temporary change our MAC address, we need to turn off the network interface first by running this command ifconfig eth0 down
3. After that we can configure the new MAC address ifconfig eth0 hw ether 00:00:00:00:00:02you can change the MAC address using this hexadecimal format XX:XX:XX:XX:XX:XX
4. Now we can turn on the network interface again ifconfig eth0 up
5. And the last we can check again our MAC whether it's change or not. if we follow until this step, MAC address will back to default after we restart our machine. Go to next page to view how to change MAC address permanently.
6.Kali Linux was built based on Debian. In Debian all the network interface was located on/etc/network/interfaces.
7. We will configure the/etc/network/interfaces. In this tutorial I will use pico text editor, but you can choose any of your favourite text editor. pico /etc/network/interfaces
8. Now we will add one line of script to change our MAC address permanently pre-up ifconfig eth0 hw ether 00:00:00:00:00:02 This script will be called on system startup.
9. If we want to restore the default MAC address,just add the#sign in front of script in step 8.
#pre-up ifconfig eth0 hw ether 00:00:00:00:00:02
