This script allows you to change the MAC (Media Access Control) address of a network interface on Linux systems. It provides functionality to generate a random address, specify a new address manually, and clear the DNS and ARP caches after the change.

Use

• The script has the following functionalities:

  • Use the -r option to generate a new valid random MAC in Linux format.

  • Use the -m option to specify the new MAC address you want to apply.

  • The script retrieves the current MAC address of the specified interface.

  • Change MAC address: The script modifies the MAC address of the chosen interface.

  • Clear cache (Linux): After changing the MAC, the script clears the DNS and ARP caches to avoid connectivity issues.

• Clone this repository and install the dependencies with the following command:

    git clone https://github.com/0x5FE/mac_adress_changer.git
  

• navigate to the folder

    cd mac-changer
  

• Run the script:

    python mac_changer.py -p linux <interface> [options]
  

• Replace with the name of the network interface you want to modify.

  Possible Errors and Solutions

• Unsupported Platform If you try to use the script on an operating system other than Linux, you will receive a error. Currently, Windows support is still under development.

• Error: ModuleNotFoundError No module named 'argparse' Solution: Install the argparse package using pip install argparse.

• Subprocess.CalledProcessError Command 'macchanger' failed with exit status 1 Solution: Check if the macchanger package is installed and accessible on your system. You can try to install the package using your operating system's package manager.

• Error: ValueError Please specify either -r or -m option Solution: You need to specify the -r option to generate a random address or the -m option to manually provide a new address.

Future improvements

• Implement functionalities to change the MAC address on Windows systems.
• Create a graphical interface to facilitate the use of the script.
• Implement cleaning of DNS and ARP caches for Windows systems.
• Allow the generation of MACs with specific characteristics (e.g. prefix or suffix).
• Add validation to ensure that the MAC provided is a valid address in the correct format.

Notice

• This script is intended for educational and research purposes.

• Changing the MAC address of your network interface may affect connectivity and violate terms of service for specific networks.

• Use this script responsibly and understand the possible impacts before using it.
