So can someone please clarify on what exactly Comcast's executable
does? Does this cause the activation of the filtering by MAC address?
Assume for a second that they do start filtering by MAC address. What
stops me from doing:
/sbin/ifconfig eth0 hw ether 11:22:33:44:55:66
Or even if I can't, why can't I just find that old ethernet card and put
it back in? I'm assuming that the MAC they will have in their database
is the one of the card that was originally provided with the service.
But then again, doesn't the cable modem (physical box unit) have a MAC
address of its own? I understand that this will not help if you have a
Linksys type router or some other proprietary box.
