A Python script to change the MAC address of a network interface. This script works for both Windows and Unix-based systems, such as Linux and macOS. The user can specify the network interface and the new MAC address to be set.

Features

• Supports both Windows and Unix-based operating systems.
• Allows changing the MAC address of any specified network interface.
• Verifies if the script is run with administrator/root privileges.
• Provides feedback about the current and updated MAC address.

Requirements

• Python 3.x
• Administrator or root privileges (needed to change MAC addresses)

Dependencies

• subprocess: Used to run system commands.
• re: Regular expression library for parsing MAC addresses.
• argparse: Library for command-line argument parsing.

Usage

1. Clone the repository or download the script.

   git clone https://github.com/BaseMax/mac-address-changer
   cd mac-address-changer

2. Run the script with the necessary arguments.

   python3 mac_changer.py -i <interface> -m <new_mac_address>

   • -i or --interface: The network interface to modify (e.g., eth0, wlan0).
   • -m or --mac: The new MAC address to assign (e.g., 00:11:22:33:44:55).

Example Usage

Change the MAC address of eth0 to 00:11:22:33:44:55:

python3 mac_changer.py -i eth0 -m 00:11:22:33:44:55

Functions

• is_windows(): Returns True if the operating system is Windows.
• is_admin(): Checks if the script is running with administrator privileges.
• get_current_mac(interface): Retrieves the current MAC address of the specified network interface.
• change_mac(interface, new_mac): Changes the MAC address of the specified network interface to the provided new_mac.
• validate_mac(mac): Validates if the provided MAC address follows the correct format.
