What is MAC address
According to Wikipedia, the MAC address is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.
Why Change the MAC Address?
Normally we don’t need to change the MAC address of our system. But if any wireless system has blocked your main MAC, you may need to change the MAC to access the network.
Change MAC address
We can easily spoof MAC address in Kali. Run this command to see your MAC addess:
sudo ifconfig
Output:
Look at eth0 Ethernet interface. 00:15:5d:e1:70:a7 is the MAC address of my system.
To change the MAC to random address run these commands:
sudo ifconfig eth0 down
sudo macchanger -r eth0
sudo ifconfig eth0 upSet a Specific MAC address:
sudo ifconfig eth0 down
sudo macchanger -m 00:15:70:00:20:75 eth0
sudo ifconfig eth0 upDone! Now you can run sudo ifconfig to see the new MAC.
