Introduction📘

The Network Scanner Tool is a powerful command-line network reconnaissance application built using Scapy. It provides a flexible and efficient method for scanning network ports, helping network administrators and security professionals identify open ports and potential vulnerabilities.

Technical Description⚙️

The tool implements a TCP port scanning mechanism with advanced features:

  • SYN Scanning: Uses half-open TCP scanning technique
  • Progress Visualization: Integrated progress bar with colorful output
  • Flexible Port Scanning:
    • Scan specific ports
    • Scan port ranges
    • Detailed error handling

Key Technical Components:

# Packet crafting example
tcp_packet = IP(dst=target) / TCP(dport=port, flags="S")
response = sr1(tcp_packet, timeout=1, verbose=False)

Technologies Used💻

  • Python 3.x
    • Network programming
    • Command-line argument parsing
  • Scapy
    • Packet manipulation
    • Network scanning
  • Additional Libraries
    • tqdm: Progress bar visualization
    • colorama: Colored console output
    • argparse: Command-line argument handling

Main Features🌟

  • TCP Port Scanning
    • SYN half-open scanning technique
    • Supports single port and port range scanning
  • User-Friendly Interface
    • Colorful console output
    • Progress bar during scanning
    • Clear result presentation
  • Flexible Scanning Options
    • Specify target IP/hostname
    • Scan multiple or range of ports

Installation🔧

  1. Prerequisites:

    • Python 3.7+
    • Root/Administrator privileges

  2. Required Libraries:

    pip install scapy tqdm colorama

  3. Clone Repository:

    git clone https://github.com/RobCyberLab/Network-Scanner-Tool.git
cd network-scanner-tool

Usage Examples🚀

Scan Specific Ports:

python scanner.py TCP 192.168.1.1 22 80 443

Scan Port Range:

python scanner.py TCP 192.168.1.1 0 1000 --range

Possible Improvements🔬

  • Additional Scan Types
    • UDP scanning
    • XMAS scan
    • FIN scan
  • Enhanced Reporting
    • JSON/CSV output
    • Detailed port service detection
  • Performance Optimization
    • Parallel scanning
    • Adaptive timing strategies
  • Advanced Features
    • OS fingerprinting
    • Banner grabbing
    • Stealth scanning techniques

Security and Legal Considerations⚖️

🚨 Important:

  • Use only on networks you own or have explicit permission to scan
  • Unauthorized network scanning may be illegal
  • Respect privacy and network usage policies
