Before changing your mac address you have to bring your interface down.

Bring Interface down

Before changing we must bring our interface down. I am connected to internet with wired[ethernet] interface. So if you are connected to internet with wireless[wifi] then type wlan0 instead of eth0.

root@seven:~# ifconfig eth0 down

Change MAC

root@seven:~# macchanger -r eth0

  1. -r   flag is for generating random address.It basically tells macchanger to give any random address.
  2. eth0   Which card you want to change MAC on.If your card is wireless then write wlan0.

Now type the following command to enable your interface again.that should be it.

root@seven:~# ifconfig eth0 up
