Change MAC Address Permanently

Change MAC Address Permanently

It is well know that through the ip and ifconfig commands it is possible to change a MAC address temporarily, meaning the change will not persist across host reboots.

But what if you would like to change your MAC address in a more permanent fashion? Is there a way to, through software, permanently change your network interface card's MAC address?

It turns out the answer is yes, and the tool to do so is called ethtool.

Ethtool

Ethtool comes pre-installed on many stock distributions of Linux, but can also be installed from your package manager of choice if necessary.
