The fun begin..
Take down the
This will deactivate
Take down the
eth0 interface:
ifconfig eth0 down
eth0.
Change the IP address of
eth0:
ifconfig eth0 111.111.0.0
Change the hardware address of
eth0:
ifconfig eth0 hw ether aa:aa:aa:aa:aa:aa
Bring up the interface
eth0:
ifconfig eth0 up
Now run ifconfig..
Output:
ifconfig eth0
