FastPortScan

FastPortScan is a high-speed, multithreaded port scanner built with Python. It can perform both normal and stealth (SYN) scans, allowing you to efficiently identify open ports on a target machine. The tool is designed to be fast, customizable, and easy to use.

⚡ Features

✅ Ultra-fast scanning using multithreading
✅ Full TCP scan (Default mode)
✅ Stealth SYN scan (--stealth mode)
✅ Custom port range selection
✅ Color-coded output using colorama
✅ Progress bar with tqdm
✅ Graceful exit on Ctrl+C, ensuring all findings are displayed
✅ Lightweight & easy to use

🚀 Installation

Ensure you have Python 3 installed. Then, install the required dependencies:

pip install colorama tqdm

🔧 Usage

Run the tool with the desired options:

Basic Scan (Full TCP Handshake)

python3 FastPortScan.py -ip <TARGET_IP>

This scans all 65,535 ports on the target.

Specify Port Range

python3 FastPortScan.py -ip <TARGET_IP> --starting 1 --ending 1024

This scans only ports 1 to 1024.

Stealth Mode (SYN Scan - Requires Root)

sudo python3 FastPortScan.py -ip <TARGET_IP> --stealth

This sends SYN packets instead of a full TCP handshake, making the scan stealthier.

Example Output

============================================
      Welcome to the Fast Port Scanner
============================================

Starting scan on 10.10.11.24 from port 1 to 65535...

port 53 - open
port 80 - open
port 443 - open
