Today I’ll tell a smart trick to change your mac address of a NIC card in linux-
Just to this and see :
ifconfig eth0 down
ifconfig eth0 hw ether 00:19:7e:53:8c:a3
ifconfig eth0 up
eth0 – is hardware name of your network interface, you can use
ip link to see all available interfaces identified by your system.
00:19:7e:53:8c:a3 is new MAC address you’d like to apply to the NIC.
These commands should be added into startup scripts if you require them to appear after Linux system reboots. This works on any distribution like Fedora, Ubuntu, Debian, RedHat, Suse whatever.
