Campus Gateway Auto-Login Service for Windows

An automated, lightweight Python service designed to maintain continuous internet connectivity through the CCIT / Sophos / Cyberoam captive portal (http://182.43.0.22:347/).

It periodically verifies external internet access, automatically re-authenticates when disconnected, and sends keep-alive pings to prevent idle session logouts—all running silently in the background.

---

Features

• Silent Operation: Uses pure Python socket checks instead of system pings (os.system), preventing command prompt windows from flashing every cycle.
• Automatic Re-Authentication: Detects offline status and sends mode=191 POST requests directly to login.xml.
• Session Keep-Alive: Sends periodic mode=192 status pings to prevent gateway idle timeouts.
• Zero Overhead: Consumes minimal CPU and memory resources.
• Logging: Writes timestamped logs to log.txt for easy troubleshooting.

---

Prerequisites

• OS: Windows 10 / 11
• Python: Python 3.8 or higher
• Dependencies: requests library

Install requests if you haven't already:

python -m pip install requests

Setup & Installation

Step 1: Script Configuration

1. Place auto_login.py in your target folder (e.g., C:\AutoLogin\).
2. Open auto_login.py and set your gateway URL, username, and password.

---

Step 2: Configure Windows Task Scheduler (Silent Background Execution)

To run the script automatically in the background when you log into Windows without command prompt popups:

Find pythonw.exe Path

Open Command Prompt and run:

where pythonw.exe

Create the Task

1. Press Win + R, type taskschd.msc, and press Enter.
2. In the right panel, click Create Task... (do not select Create Basic Task).

Configure the Properties

General Tab:

• Name: CCIT Auto Login
• Select: Run only when user is logged on
• Check: Run with highest privileges

Triggers Tab:

• Click New... ➜ Begin the task: At log on ➜ Click OK.

Actions Tab:

• Click New... ➜ Action: Start a program
• Program/script: Paste the full path to pythonw.exe
• Add arguments: auto_login.py
• Start in: C:\AutoLogin\
• Click OK.
• Click OK to save the task.

Managing the Background Service

Start Service: Right-click CCIT Auto Login in Task Scheduler and select Run.

Verify Execution: Open Command Prompt and run:

tasklist | findstr python

Look for pythonw.exe in the output.

Check Activity: Inspect C:\AutoLogin\log.txt for live connection logs.

Stop Service: Run the following in Command Prompt:

taskkill /F /IM pythonw.exe

---

Troubleshooting

• Task not running? Verify the pythonw.exe path is correct and auto_login.py is in the specified directory.
• Check logs: Review log.txt for detailed error messages and connection status.
• Python not found? Ensure Python is installed and added to your system PATH.
