macchanger_daeion

A small systemd-based utility that randomizes (spoofs) network interface MAC addresses on system boot and can be run periodically via a systemd timer. It uses the well-known macchanger utility and is intended for systemd-based Linux distributions (Arch, Debian/Ubuntu, Fedora, etc.).

Why use this

• Improve privacy by rotating MAC addresses to reduce device tracking on networks.
• Automatically randomize MAC addresses at boot and optionally at configured intervals.
• Lightweight: uses existing system utilities and a simple shell script + systemd units.

Requirements

• A systemd-based Linux distribution.
• macchanger installed and available in PATH.
• Root privileges to change MAC addresses and install systemd units.

Supported platforms

• Any Linux distribution that uses systemd and provides macchanger (Arch Linux, Debian/Ubuntu, Fedora, and derivatives).

Quick features

• Randomizes MAC at boot via a systemd service.
• Optional periodic randomization via a systemd timer (configurable interval).
• Minimal dependencies and easy to inspect/modify.

Installation

1. Install macchanger

• Arch / Manjaro:

  sudo pacman -Syu macchanger

• Debian / Ubuntu:

  sudo apt update
  sudo apt install macchanger

• Fedora:

  sudo dnf install macchanger

2. Clone this repository

git clone https://github.com/Pushpenderrathore/macchanger_daeion.git
cd macchanger_daeion

3. Install the script and systemd service

# Install the main script
sudo cp change-mac.sh /usr/local/bin/change-mac.sh
sudo chmod +x /usr/local/bin/change-mac.sh

# Install the systemd service unit
sudo cp macchanger.service /etc/systemd/system/macchanger.service

# Reload systemd, enable and start the service
sudo systemctl daemon-reload
sudo systemctl enable --now macchanger.service

Notes:

• The example above places the script in /usr/local/bin and the systemd unit in /etc/systemd/system. Adjust paths if you prefer a different layout.
• You may need to edit change-mac.sh to specify which interfaces to randomize (see Configuration).

Configuration

• Interfaces

  • The script can be configured to target specific interfaces (for example wlp3s0, enp0s31f6) or all non-loopback interfaces. Edit change-mac.sh to list desired interface names or adjust its filtering logic.
  • If the script supports arguments or environment variables for interface selection, you may pass them via the systemd unit (see the service file or set a drop-in unit).

• Logging

  • The service writes to the system journal. Use journalctl to view logs.

Usage

• Check status:

  sudo systemctl status macchanger.service

• Follow logs in real time:

  sudo journalctl -u macchanger.service -f

• Run the script manually (useful for testing):

  sudo /usr/local/bin/change-mac.sh

• To test on a single interface :

  sudo /usr/local/bin/change-mac.sh wlp13s0

Periodic randomization (systemd service)

[Unit]
Description=Randomize MAC address at boot
After=network-pre.target
Before=network.target
Wants=network-pre.target

[Service]
Type=simple
ExecStart=/usr/local/bin/change-mac.sh
Restart=always

[Install]
WantedBy=multi-user.target

OR-Direct run option :

sudo ./install.sh   
sudo systemctl status macchanger.service

When run, ./install.sh it will trigger macchanger.service at the system Deamonic level to configure everything.

• macchanger.service — systemd service unit to run the script at boot (and on-demand).
• macchanger.timer — optional systemd timer unit to run the service periodically (example).
• install.sh — convenience installation script (one-shot installer).

Contributing

Contributions are welcome. Typical ways to contribute:

• Add support for additional distributions or interfaces.
• Improve the script's robustness and logging.
• Add automated tests or packaging (AUR, DEB, RPM).
• Improve documentation and add examples.

Please follow the repository's code of conduct and open a pull request. If you want me to prepare a PR with the revised README, tell me and I can create one (I'll need the repository owner permission to push).

Security & privacy considerations

• Changing a MAC address may violate network policies in some environments. Do not use this on networks where spoofing is prohibited.
• Changing the MAC of an active interface may temporarily disrupt network connectivity.
• Keep in mind that MAC randomization alone does not guarantee anonymity; use it in combination with other privacy measures if needed.
