"ifconfig up" resets spoofed mac to hardware mac
if i spoof the MAC on wlan0, when i bring the device up it resets to the hardware mac automagically. I am running Ubuntu 10.04 on a eee netbook. If i bring wlan0 down, change the MAC (any number of ways, ifconfig, macchanger, etc.), when i issue 'ifconfig up' the MAC is reset to the hardware MAC. I know it's possible to do; it works when i do it in Backtrack (which is ubuntu based) with the same hardware, also, spoofing eth0 works fine in ubuntu 10.04.

What about just adding up to the end of the configuration statement?

ifconfig wlan0 down
ifconfig wlan0 <configuration> up

Nope, doesn't work. That indicates to me that it's not something inherent in the command but rather something that ifconfig "calls" maybe it is something with the driver. i am going to see what driver Backtrack uses on my machine to eliminate that as a possibility.
