Openssl rand -hex 6|fold -w2|paste -sd:. Stay tuned with It’s FOSS for more Linux tutorial and tips.Here are five other options, all of which use random bits for the least significant bit of the most significant byte that indicates if the address is unicast or multicast and for the second-least significant bit of the most significant byte that indicates if the address is universally or locally administered. You have successfully changed the MAC address in true Linux style. Now, verify new MAC address: ip link show enp0s31f6 Next, set the new MAC using command: sudo ip link set dev enp0s31f6 address XX:XX:XX:XX:XX:XXįinally, turn the network back on with this command: sudo ip link set dev enp0s31f6 up I would recommend using Macchanger but if you don’t want to use it, there is another way to change the MAC address in Linux.įirst, turn off the network card using command: sudo ip link set dev enp0s31f6 down Method 2: Changing Mac address using iproute2 You can always check the man page for more details.
