CyberPulse Network Scanner

A Python-based GUI tool designed for IT support professionals to troubleshoot network connectivity issues. Built with customtkinter, it features a modern, dark-themed interface with real-time logs, dual progress bars, and a scrollable results table, making it ideal for diagnosing network devices and services.

Features

• Network Scanning: Scans subnets (e.g., 192.168.0.0/24) to detect live hosts and guess OS via TTL.
• Port Checking: Scans common ports (21, 22, 80, 443) or custom ranges with concurrent threading.
• Real-Time Feedback: Side-by-side logs and progress bars for host discovery and port scanning.
• Results Table: Displays IP, OS, and open ports in a scrollable table.
• Scan History: Saves up to 5 past scans in a sidebar for quick review.
• Export Options: Saves results as JSON or CSV for reporting.
• User-Friendly Design: Includes tooltips, inline error messages, and a cancel scan feature.

Installation

1. Clone the Repository:

   git clone https://github.com/your-username/network-scanner.git
   cd network-scanner

2. Install Dependencies:

   pip install -r requirements.txt

3. Requirements:

   • Python 3.8+
   • customtkinter (included in requirements.txt)
   • Windows/Linux (for ping compatibility)

Usage

1. Run the application:

   python network_scanner.py

2. Enter a subnet (e.g., 192.168.1), select ports (checkboxes or custom, e.g., 8080,1000-2000), and set a timeout (e.g., 1.0).

3. Click Initiate Scan to start.

4. Monitor logs and progress bars in real-time.

5. View results in the table, save as JSON/CSV, or load past scans from the history sidebar.

Screenshots

• Main Interface: Input fields and history sidebar.
• Scan in Progress: Real-time logs and progress bars.
• Results Table: Detailed scan results.

Testing

• Setup: Install dependencies and run python network_scanner.py.
• Scan: Test with subnet 192.168.1, ports 80/443, and timeout 1.0.
• Features: Verify logs, progress bars, results table, history, and export.
• Edge Cases: Test invalid inputs (e.g., subnet 256.168.0) and window resizing.

Notes

• Ensure your firewall allows ICMP (ping) and TCP connections for scanning.
• Designed for Level 1 IT support roles, showcasing skills in Python, GUI design, networking, and user-centric error handling.
• Future enhancements may include persistent history, button icons, and results sorting.
