Do you, or someone else, know of a good howto on how to use MAC addresses like that? Given this thing is usually remotely accessed, I really need it to be consistent with or without the card. Maybe you have a bookmarked link saved somewhere. I'm on openrc to. I'll google around but you, or someone else here, may have a really good and simple howto link. Well, learned something in the past couple days. Thanks. Dale :-) :-)
