A Media Access Control address or MAC address is a unique identifier assigned to network interfaces. This uses for communications when connected to the network. Although MAC addresses is a unique identifier of network adapter, we can change it. In Backtrack 5 R3 there is a tool to change MAC address, it's called macchanger. But remember, the MAC address has a rule of notation so you can change it randomly.
Before you change the MAC address you must turn off the network interface. Open your terminal and run this command
ifconfig eth0 down

eth0 is a network interface (LAN), if you want change MAC address of wireless interface you can change eth0 with wlan0

Then change the MAC address
macchanger --mac xx:xx:xx:xx:xx:xx eth0

After that, turn on the network adapter.
ifcofig eth0 up



That's all. You can check your MAC address with ifconfig -a
