How to set mac address change forever?

Could anyone teach me how to set mac address change forever in bubblegum 96 Debian OS?Thanks!

Is the current MAC hard coded (same on all boards)? If so, what is it?

set command : sudo ifconfig
I get information like this:
enx00e09c100ec1 Link encap:Ethernet HWaddr 00:e0:9c:10:0e:c1

enx00e09c100ec1 is USB network device,and I want to set differnet mac address to every bubblegum 96 board.
Could you give me some useful point?Thanks!

Firstly, sorry it took so long to get back on this. I’m afraid a bot blocked you for “typing too fast” and I didn’t spot it until today (copy 'n paste is useful but it is also a signature move of spammers).

The wlan0 should already be unique for each board (94:a1:a2:75:0e:72 is issued by Ampak who make the wlan0 module).

You mean that you want to modify the MAC address on the USB adapter you have? I’ve never tried it but I think you can do that via the interfaces file: Hacking/Tools/Network/Changing Your MAC Address/Linux - Wikibooks, open books for an open world
