[Linux Mint] MAC randomizer

put this in /usr/lib/NetworkManager/conf.d/30-nm-privacy.conf, reboot

[connection-mac-randomization]
ethernet.cloned-mac-address=random
wifi.cloned-mac-address=random

this is not the only way that carriers can detect tethering:

  • mtu detection
  • dun apn usage
  • deep packet inspection
