Changing the MAC address
Steps
The following commands allow you to change the MAC address of a network interface to any random address other than the original. This is useful when you want to hide your connection to a device on a network under attack.
1. Shutdown wlan1 interface:
ifconfig wlan1 down
2. Set random vendor MAC of the same kind:
macchanger -a wlan1
3. Turn on wlan1 interface:
ifconfig wlan1 up
