Change Your MAC Address in Linux

For example, lets change the MAC address of your first netwrok card, usually called eth0.

Let’s swith to being the root user and view the current MAC address:-

ifconfig eth0

1. You should get something similiar:-

[root@rhel-5new ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 08:00:27:2C:D2:B5
inet addr:192.168.0.108 Bcast:192.168.0.255 Mask:255.255.255.0
inet6 addr: fe80::a00:27ff:fe2c:d2b5/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:20545 errors:0 dropped:0 overruns:0 frame:0
TX packets:18348 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:10083277 (9.6 MiB) TX bytes:7489363 (7.1 MiB)
Interrupt:11 Base address:0xd020

The MAC address is listed next to the HWAddr column, which is 08:00:27:2C:D2:B5 in this case.

2. We’ll change it. First shutdown the network interface.

ifconfig eth0 down

3. Now change it to say, 08:00:27:2C:D2:B4.

ifconfig eth0 hw ether 00:00:27:2c:d2:b4

4. Bring the interface up.

ifconfig eth0 up

5. Finally, lets have a look at the new mac address.

[root@rhel-5new ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:00:27:2C:D2:B4
inet addr:192.168.0.108 Bcast:192.168.0.255 Mask:255.255.255.0
