changing a nic's mac address, freebsd6
Hello, I've got an rl0 nic on a freebsd6 machine that i need to change it's mac address on a tempoary basis. I will want to change it back when my testing is complete. I read this was feasible with opbnbsd, and was wondering if the capability was available in fbsd6? Also, does it matter which tempoary mac address i give the card? Thanks.

You can use ifconfig rl0 ether $NEWMAC to change the mac address, ether has been around for a while and doesn't require FreeBSD 6.x. You're free to choose any address you like, but most of the time taking a free one (not already taken in your network) makes sense.

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. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

You can do this with ifconfig and the link parameter. i.e # /sbin/ifconfig rl0 link $NEWMACADDRESS cheers, Anth ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
