Hey,
I've been trying to change my MAC address by running the follow:

Code:
 #ifconfig eth0 down
Code:
 #ifconfig eth0 hw ether "NEW_MAC_ADDRESS"
Code:
 #ifconfig eth0 up
running the following results in the same issue:

Code:
#macchanger -r eth0
I've run those commands both on bridged network and NAT, using VM VirtualBox
any help will be appreciated
