Same here. Strange that nobody could get around this problem.

He's doing it wrong. After detaching with airport -z It's:
sudo ifconfig en1 lladdr 00:11:22:33:44:55 etc
Then use the menubar to reattach to your wireless network

It seems to work perfectly for en0 but not of an external USB WLAN card.
on Snow Leapord

1. vi /usr/local/machanger.sh
2. Append the shell script above in this file (replace en0 to $1 to make it generic)
3. Put your Airport Off
4. /usr/local/macchanger.sh en0
5. Connect to you desired AP
6. ifconfig -a

You should see the new MAC address.

Hi Tom
There is a way around that.
assuming you don't mind it running at certain intervals.
you can do a ==> man crontab.
from there you can set-up the root user to run the command for you.
Cron will allow all sorts of day's hours mins weeks and even years that this thing can be run.
I use this method where the root's crontab runs my script 2 times per week.
No clicking required. it all just happens.. nice to have a random spinning mac addr

cheers

Allow me to clarify, because my last post seems unclear.

I want to make an app or an executable script to run your script w/out going thru terminal. Like double click an icon on the desktop and away she goes. I understand that you need sudo to run “airport -z”, so is there a way around that?

I am indeed running on a mac.

I used “sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/sbin/airport” to make a link to airport, then just replaced the/usr/bin line with “sudo airport -z”. the end result says it changed the mac address, but it actually did not after running ifconfig to check.

I guess what I am actually trying to do is create an automated way to randomize my mac address. Like using automator or make an applescript. though I am a newb when it comes to those.

Hi Tom

This just means you do not have the airport command in its right location
you can find it's location by putting this command (below) in the terminal.

find / -name airport -print 2>/dev/null

One of the responses will show you where the airport command will be.
Also .. just a thought.. you are running a mac right ? if not I will have to write a different script to allow this to work.
NOTE::This concept will work on any Unix computer.

cheers

Expected end of line, etc. but found “/”. error

highlights the / of the /usr/sbin/airport -z portion of code

dunno much about scripting, but can you advise on how to make an apple script with this?
