How To Change MAC Address On Kali Linux

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 00:00:00:00:00:02

you 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.

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

Conclusion:
1. Changing MAC address usually needed for privacy and prevent tracking in the local network about our hardware information(e.g: in public wi-fi network).

2. Some network administrator they make blocking rule in proxy or router by adding the MAC address. To ensure interoperability and preventing being blocked by the proxy or router blacklist rule, we can change our MAC address.
