[CentOS] Trying to override MAC addr

[GKH]

I just did it like this:

ifconfig enp3s0

enp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.241.27.154  netmask 255.255.255.0  broadcast 10.241.27.255
        inet6 fe80::210:18ff:fe04:4d0  prefixlen 64  scopeid 0x20<link>
        ether 00:10:18:04:04:d0  txqueuelen 1000  (Ethernet)
        RX packets 429591  bytes 41991957 (40.0 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 249536  bytes 19108398 (18.2 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
        device interrupt 18

ifconfig enp3s0 hw ether 00:10:18:04:04:d7

ifconfig enp3s0
enp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.241.27.154  netmask 255.255.255.0  broadcast 10.241.27.255
        inet6 fe80::210:18ff:fe04:4d0  prefixlen 64  scopeid 0x20<link>
        ether 00:10:18:04:04:d7  txqueuelen 1000  (Ethernet)
        RX packets 429615  bytes 41994383 (40.0 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 249549  bytes 19109350 (18.2 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
        device interrupt 18
Done!
