That said, to do it in Linux,you can install "macchanger" from your regular repository (or grab it from http://gnu.org/software/macchanger/ ).

Assuming the networkinterfaceyou want to change is "eth0", from a shellprompt you'll want to do the following (with root permisisons):

Code:

ifconfig eth0 down
macchanger -r eth0
ifconfig eth0 up

"ifconfig eth0 down" to disable the eth0 interface.
"macchanger -r eth0" to assign a new address (the -r flag randomizes it, or use -e instead to assign assign a random address using the same vendor.)
"ifconfig eth0 up" to bring the interface back up.

If it's a wireless card as opposed to an ethernet card, the interfacewill probablybe "wlan0" instead of "eth0" but you can list the availableinterfaces by typing "ip link show" or "ifconfig".


Then justadd a cron job (sudo crontab -e) toschedule it to runas frequently as you want.

Yeah that's ultimately what I realized, the reason I thought there may be another way was that I have this "WIFI de-auther" which is just a motherboard with a custom firmware that this guy made and it has an option that makes it change the mac constantly like every minute (might be more like every 10 seconds actually, I don't remember.) But yeah from what I can tell whenever you're changing it on normal devices it has to have it disabled.
