    Cool, ha? Basically it doesn't change the MAC adress, because you can't do that, but you can change the MAC adress that packets are carrying.

    That's just MAC address spoofing. Some ISP's require something like that to be done to (try) and stop u sharing the net connection

    Not only does EVERY card have a MAC address, i have heard that they are supposedly unique aswell. But i dont see how this is possible.....

    the first 3 parts of a MAC address are for the manfacturer, 00:01:02 being 3com.

    This means that each manufacturer can only make 00:00:00 -> hh:hh:hh cards (cant b arsed to work out what that is! hehe)
    00:00:00 -> ff:ff:ff

    And yes, MAC addresses are unique to every ethernet interface. It's a 48-bit code, so there are 281,474,976,710,656 possibilities.

    Why did you think that? Lack of coffee. That's the only reason geeks make mistakes.

    I am using SuSe 9.2 and i don't seem to have ifconfig. Is it something that needs to be installed with YaST or is there a different ip tool for suse.
