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 www.google.com PING www.l.google.com (74.125.43.105) 56(84) bytes of data. 64 bytes from bw-in-f105.1e100.net (74.125.43.105): icmp_seq=1 ttl=53 time=220 ms 64 bytes from bw-in-f105.1e100.net (74.125.43.105): icmp_seq=2 ttl=53 time=220 ms 64 bytes from bw-in-f105.1e100.net (74.125.43.105): icmp_seq=3 ttl=53 time=219 ms 64 bytes from bw-in-f105.1e100.net (74.125.43.105): icmp_seq=4 ttl=53 time=220 ms 64 bytes from bw-in-f105.1e100.net (74.125.43.105): icmp_seq=5 ttl=53 time=220 ms ^C --- www.l.google.com 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
