Automatically Log In to a Website on LAN Connection with Python

If you want a Python script to open a webpage and log into a website automatically when you connect to a LAN, Selenium and psutil libraries can be used for browser automation and network connection monitoring, respectively. This guide provides a comprehensive step-by-step process to achieve this.

Step 1: Install Required Libraries

First, ensure you have the necessary libraries installed:

pip install selenium psutil

Step 2: Set Up WebDriver

You will need a WebDriver for the browser you intend to use, such as Chrome or Firefox. For Chrome, download the ChromeDriver from here and ensure it is in your PATH.

Step 3: Write the Python Script

Below is a sample script that waits for a LAN connection and then logs into a specified website:

```python import time import psutil from selenium import webdriver from import By from import Service as ChromeService from webdriver_ import ChromeDriverManager # Function to check if connected to a LAN def is_connected_to_lan(): for iface_addrs in _if_addrs().items: for addr in iface_addrs: if _INET: # Check for IPv4 return True return False # Function to perform login def login_to_website(username, password): # Set up the WebDriver browser (serviceChromeService(ChromeDriverManager().install())) # Open the website (replace with actual login URL) ('') # Locate the username and password fields and the login button username_field _element(, 'username') # Adjust according to the HTML structure password_field _element(, 'password') # Adjust according to the HTML structure login_button _element(By.XPATH, '//button[@type') # Adjust according to the HTML structure # Enter credentials username__keys(username) password__keys(password) # Click the login button login_() # Main function to monitor LAN connection def main(): print('Monitoring LAN connection...') while True: if is_connected_to_lan(): print('Connected to LAN. Logging in...') login_to_website('your_username', 'your_password') # Replace with actual credentials break (5) # Check every 5 seconds if __name__ '__main__': main() ```

Step 4: Customize the Script

Replace with the actual login URL of the website you want to access.

Adjust the element locators (e.g., username field, password field, login button) according to the website's HTML structure. Use tools like Chrome DevTools to inspect the elements. Replace your_username and your_password with your actual credentials.

Step 5: Running the Script

You can run this script in the background. To start it automatically when your computer connects to a LAN, consider adding it to your system's startup applications or using a script that runs at boot.

Important Note

Be cautious when handling credentials in scripts. Consider using environment variables or secure storage methods to manage sensitive information. Additionally, ensure that your use of automation complies with the website's terms of service.
