Last October the well-known hacking group Chaos Computer Club revealed that the German state police had been monitoring the computers of ordinary citizens using specially designed surveillance software.

One of the machines was actually working. But moving the connection to a different machine was not, so I suspected some form of association between the port and the mac address.
To prove it, I decided to change the MAC address of my Mac Book Pro and copy the MAC address of the working machine.

- Create the interface
ifconfig vlan<nn> create
- Associate the interface with the vlan tag and physical interface
ifconfig vlan<nn> vlan 2 vlandev en0
- Add an IP address to the interface
ifconfig vlan<nn> inet <IP> netmask <MASK>
- Bring the interface up
ifconfig vlan<nn> up
All these commands need to be executed as root.
