Presumably if one needed to change a MAC address one would already know the MAC address one needed to change to. Otherwise make sure you are not using an address currently in use on your network or the next router over. Probably best to increment your current MAC by one. Once Upon A Time I initialized a cable modem connection at a remote office using my Mac PowerBook then replaced it with a FreeBSD machine dedicated to serve as that office's router, firewall, and VPN gateway. Rather than reinitialize the cable modem service with the FreeBSD interface's MAC I left it using my PowerBook's MAC. The detriment was I could no longer use my PowerBook in that office because it confused the FreeBSD machine which saw another using its MAC address. To set the MAC address before any other networking starts (such as DHCP) create /etc/start_if.<interface name> #/bin/sh ifconfig <interface name> lladdr 00:11:22:33:44:55 If you make up an address the first octet probably should be 0 as there are bits in that field which have special meaning. -- David Kelly N4HHE, [EMAIL PROTECTED] ======================================================================== Whom computers would destroy, they must first drive mad. _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
