Automatic Randomised MAC for Linux

Project created to enhance privacy of desktop linux by randomising the MAC address everytime the system is booted.

Requirements

1. macchanger

   sudo apt install macchanger

2. systemd (included in most of the popular distros)

   This automation tool was written with systemd as target. If you do not have systemd, you can use crontab.

Installation

1. Clone this repo and cd into it

   git clone https://github.com/ShobanChiddarth/randomised_mac_linux.git
   cd randomised_mac_linux

2. Make the script as executable

   chmod +x ./randomise_MACs.sh

3. Copy the script into /usr/bin

   sudo cp randomise_MACs.sh /usr/bin/

4. Copy the systemd service file into /etc/systemd/system

   sudo cp randomise_MACs.service /etc/systemd/system/

5. Reload systemd

   sudo systemctl daemon-reload

6. Enable the service to run on boot

   sudo systemctl enable randomise_MACs

7. Note down the MAC addresses of alive network interfaces

   sudo ifconfig

8. Start the systemd service right now to check if the MAC addresses are actually being changed

   sudo systemctl start randomise_MACs

9. Run ifconfig again and compare the output with the previous run

   sudo ifconfig

10. If it is different, it means the script is working and your MAC addresses will change on each boot.
