Very unusual request here, I know you aren't normally meant to change your MAC address since it's burned into the interface you are using, but I am networking 2 raspberry Pi zeros together, each with a USB to ethernet attachment where the manufacturer used the EXACT SAME mac address for both modules. So now I need to manually change one.
I've read a lot of instruction saying to do that through
/etc/network/interfaces but I've also read that using that file is now totally outdated so there ought to be a more correct way of making this change. Would that be through
/etc/dhcpcd.conf - and if so what is the command to be written?
