People! What are you talking about??? I want to change my Mac address and I know nothing about computers! What shall I do? I don’t trust that softwares you can dawnload from the internet. Can you tell me how to do it step by step? Please???

I’ve created a script to run at the start at a session that set a new and random MAC address for my network connections on my computer at startup using this macchanger tool. This is tested on my Ubuntu 7.04 installation with Gnome Network Manager removed and Wicd installed instead. eth0 is my wired connection and eth1 my wireless connection.

1. Create a sh script with these commands to E.G. “randomMac.sh”:
killall /opt/wicd/daemon.py # closes use of eth1 by Wicd
sleep 1

ifconfig eth1 down # deactivate eth1

macchanger -A eth0 # change mac address for eth0

sleep 1 # wait a little to get different random mac addresses

macchanger -A eth1 # change mac address for eth1

ifconfig eth1 up # activates eth1

sleep 1

/opt/wicd/daemon.py 2> /dev/null # starts Wicd daemon again

sleep 4

/opt/wicd/tray-dapper.py 2> /dev/null # starts the Wicd tray

2. Read the current mac addresses with the tool ifconfig.
3. Run the script with the command “sudo sh randomMac.sh”.
4. If the mac addresses is changed correct with the script then add the command “sudo sh randomMac.sh” to your session.

This works for me. If gnome network manager is used instead of Wicd then some other way of closing it’s use of the wireless connection so macchanger can change the mac address.

You guys are missing the point of this software- it’s to get a DIFFERENT, RANDOM MAC every time you bootup.

It is also possible to set this in you /etc/network/interfaces, so it stays active even after reboot. I don’t see much point in this software?

/etc/network/interfaces
—–
auto eth0
iface eth0 inet dhcp
hwaddress ether 01:23:45:67:89:AB
—–

And this is easier??? then:

ifconfig eth0 down hw ether 00:00:00:00:00:01
ifconfig eth0 up

It is possible to change the mac address with the ifconfig command as well, but without most of the features of MAC changer.
Just write eg.: ifconfig eth1 hw ether 01:23:45:67:89:ab
