Nmap Simulator

Interactive web application that simulates the functionality of the Nmap network scanning tool.

Features

• Port Scanning Simulation: Simulate scanning of any port range (1-65535)
• Real-time Logging: View detailed scan logs as they happen
• Service Detection: Identify common services on standard ports
• Multiple Port States: Visualize open, closed, and filtered ports
• Interactive UI: Modern, responsive interface with dark mode
• Educational Content: Learn about Nmap's architecture and functionality

Getting Started

Prerequisites

• Node.js (v18 or higher)
• npm or yarn

Installation

1. Clone the repository:

git clone https://github.com/yourusername/nmap-simulator.git
cd nmap-simulator

2. Install dependencies:

npm install

3. Start the development server:

npm run dev

Usage

1. Enter a target IP address in the input field
2. Specify the port range you want to scan:
   • Start Port (1-65535)
   • End Port (1-65535)
3. Click "Start Scan" to begin the simulation
4. Watch the real-time logs and results appear
5. Toggle the architecture view to learn about Nmap's internal structure

Features in Detail

Port Scanning

• Simulates TCP port scanning
• Supports full port range (1-65535)
• Identifies common services on standard ports
• Shows port states: open, closed, filtered

Real-time Logging

• Detailed scan progress information
• Timestamp for each log entry
• Service discovery notifications
• OS detection simulation

Architecture View

• Core Engine explanation
• Network Stack details
• NSE (Nmap Scripting Engine) overview
• Data flow visualization

Educational Purpose

This simulator is designed for educational purposes to help users understand:

• How Nmap works
• Network port scanning concepts
• Service detection methods
• Network security principles

Security Note

Remember that in real-world scenarios:

• Port scanning without permission is illegal
• Always obtain authorization before scanning networks
• Use tools like Nmap responsibly and ethically
