🌐 Networking Projects Portfolio

A hands-on collection of projects to master Computer Networking from Layer 1 to Layer 7.

📖 Overview

This repository contains hands-on projects designed to help you master Computer Networking by building real tools. Instead of just reading about protocols, you will implement them to understand how everything works at a fundamental level—from raw Ethernet frames to DNS queries.

---

🎯 Learning Objectives

• 🧠 Master Networking Models: Internalize the OSI & TCP/IP models through practical implementation.
• 📦 Understand Packet Flow: See exactly how packets move, from Layer 2 up to Layer 7.
• 🛠️ Build Real Tools: Get comfortable with socket programming, protocol parsing, and traffic analysis.
• 🛡️ Cybersecurity Fundamentals: Apply core networking concepts essential for ethical hacking, DevOps, and cloud infrastructure.

📈 Why This Portfolio Matters

Understanding networking is foundational for modern tech roles. These projects simulate real-world scenarios—from reconnaissance and packet inspection to traffic manipulation. It offers a practical way to bridge the gap between theoretical textbooks and the real-world skills needed by professionals.

This repository serves both as a learning toolkit and a demonstration of applied networking fundamentals.

🐳 Running with Docker (Web Desktop)

Since many of these projects use graphical interfaces (Tkinter), this repository includes a Docker Web Desktop environment. This allows you to run all tools safely within a contained virtual desktop via your web browser.

Prerequisites

• Docker and Docker Compose

Quick Start

1. Start the container in the background:

   docker-compose up -d

2. Open your web browser and navigate to: http://localhost:6080
3. You will see a full Linux desktop interface! Open the LXTerminal from the start menu.
4. Navigate to the project directory:

   cd /root/Networking-Projects

5. Run any tool using Python 3. For example:

   python3 "10. Network Monitoring Tool/realtime_monitor.py"

To stop the container, run:

docker-compose down
