Updated Guide: How to make random MAC address at each boot

Hi Guys,

Here is my method to make your MAC address random with each reboot

1. Open terminal and navigate to Desktop:
cd Desktop

2. Use command to create new text file:
touch macc.sh

3. Edit it in gedit or leafpad and add the following text:

!#/bin/bash
ifconfig wlan0 down
macchanger -r wlan0
ifconfig wlan0 up
service network-manager restart


4. Save the file and call it macc.sh (or whatever you choose)

5. Change permissions on it to make it executable:
chmod +a macc.sh

6. in the terminal, navigate to /root/.config/

7. Add directory called auto start like this:
mkdir autostart

8. Now you should have path:
/root/.config/autostart

9. Now in terminal, type:
leafpad /root/.config/autostart/myscript.desktop

10. Paste the following:


[Desktop Entry]
Name=MyScript
GenericName=A descriptive name
Comment=Some description about your script
Exec=/root/Desktop/macc.sh
Terminal=true
Type=Application
X-GNOME-Autostart-enabled=true

11. Now save file and test it by rebooting, issue the reboot command

12. Check ifconfig and verify the mac has changed!

For some reason, this only works for me if the file is my desktop, I don't know why.

I am not sure how working with network manager will effect this if you are using the drop downs, but for boot, it randomizes my MAC everytime

Enjoy

This approach has been seen before and will only work as long as Network Manager(NM) does not attempt to connect to a network. If NM attempts to connect to a network thru the device, the mac address will either revert to the device mac or will be changed to the cloned mac address in the NM drop-down menu.

The above thread will give you a general overview and one approach to keep your spoofed mac address constant.

Pay particular attention to comments by hon3yb33 and especially the entries into the NM configuration file required to keep NM from affecting mac addresses made by macchanger.

Use crontab do crontab -e and if you have VI press I on your keyboard and you should be able to edit the file and go all the way on the bottom and type this @reboot macchanger -r wlan0 if you are using nano same thing go all the way to the bottom and type the exact same command then ctrl o and ctrl x and then reboot
