I need to tell someone my MAC address imminently so I can be added to their router, but I am not at my computer. My laptop is a Dell Latitude E6510, running Ubuntu 12.04 with an Intel 82577LM ethernet card. Can an Intel 82577LM adapter using the standard Ubuntu driver be spoofed without downloading any extra software? I obviously won't have internet access without having first done this.
I know how to spoof a MAC address in Ubuntu, but as mentioned in the ifconfig man page, this only works if the device driver supports it.
#ifconfig eth0 down #ifconfig eth0 hw ether 00:80:48:BA:d1:30 #ifconfig eth0 up
Is there some way I can know in advance if this will work?
