How is it unethical to change ones MAC address? First of all a MAC address is only used on your local LAN segment. MAC Addresses do not traverse over IP. Once your traffic hits a router the traffic is then relayed. ARP is used on individual segments to locate the MAC address that is answering for certain IP's. I just want to implement some redundancy on my cablemodem for some of the services I provide. Thus if I have a way to replace the MAC address like i can on Nokia's IPSO 3.2.1 or Sun or HP 9000's on PC hardware then i can have an entirely different standby machine assume that MAC address if it doesn't hear an answer from the other machine. > > -- > Regards, > Daniel Hauer. > http://www.enter.net "The Road To The Internet Starts There!" > *************************************************************************** > Windoze is for GAMES, UNIX is for the rest of us. > UNIX is like the sights on a loaded gun.
