How to change Mac address(virtually) on Linux box?

Log into the system as root(Superuser)

# ssh root@IP(host)

shutdown the interface

# ifdown eth0

Then execute the following command

# ifconfig eth0 hw ether 00:05:6f:62:ea:b3

start the interface

# ifup eth0

Now your system will use the above given mac address as your h/w address of your NIC

That's it folks
