How to Change MAC Address on Linux using NetworkManager

In previous post I showed how to change MAC address on Linux using ifconfig command and system-config-network tool. Today I will show you how to change MAC address using Network Manager. The method is comparatively easier.

  • Follow the steps given below to change MAC address.

  • Right click on the Network Manager applet and click "Edit Connections"

  • Select eth0 and click edit button
  • On Cloned MAC Address type the MAC address that you want to change to as shown in image below:

  • Click apply.

You are done. It was damn easy. Right!? ping to check back your internet connection.

$ $ ping
PING ( 56(84) bytes of data.
64 bytes from ( icmp_seq=1 ttl=53 time=220 ms
64 bytes from ( icmp_seq=2 ttl=53 time=220 ms
64 bytes from ( icmp_seq=3 ttl=53 time=219 ms
64 bytes from ( icmp_seq=4 ttl=53 time=220 ms
64 bytes from ( icmp_seq=5 ttl=53 time=220 ms
--- ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 4298ms
rtt min/avg/max/mdev = 219.408/220.194/220.799/0.709 ms

If you don't find "Cloned MAC address" in Network Manager update your Network Manager and then try again.
$ $ yum update NetworkManager


  1. You can follow these three steps to solve the problem
    1 .Start Device manager
    2. locate the network device
    3. open the properties and look for the entry Network Address and enter your MAC address you want.
