mac spoofing

[suthers]

Could anybody refer me to a tutorial were i could learn to write a program that 'spoofs mac address'?
I know there are plenty of programs that do it out there but mine needs to be has to have certain specifics.
I use c++, my compiler is the gcc cygwin port (dev-c++ IDE) and i use XP.
Thanks in advance,

Jules

EDIT:
Oh and i want to do this on a wireless card (in case that made a difference, i'm not an expert in communications)

why not goto start->rightclick my computer->manage->device manager->(network card)->advanced and change your mac address?

Anibody know where i could find out how to do this?
Thanks in advance,

Code: Select all

ifconfig [interface] lladdr [mac-addr]

Rather simple under BSD, permanent changes go in /etc/hostname.[interface].
