Rust Port Scanner

A simple asynchronous TCP port scanner written in Rust using tokio and clap.

Features

• Scan a range of TCP ports on a target IP or domain.
• Asynchronous and concurrent scanning for speed.
• Configurable timeout, concurrency, and port range via command-line arguments.

Requirements

• Rust (stable)
• Cargo (Rust package manager)

Installation

Clone the repository and build the project:

git clone 
cd port-scanner
cargo build --release

Usage

Run the scanner with the following options:

cargo run -- --target <IP_OR_DOMAIN> [OPTIONS]

Arguments

    --target, -t — Target IP address or domain to scan (required).

    --start-port — Starting port number (default: 1).

    --end-port — Ending port number (default: 1024).

    --timeout-ms, -T — Timeout in milliseconds for each connection attempt (default: 500).

    --concurrency, -c — Maximum number of concurrent connection attempts (default: 100).

Example

Scan ports 1 to 500 on 192.168.0.1 with 300ms timeout and concurrency of 50:

cargo run -- --target 192.168.0.1 --start-port 1 --end-port 500 --timeout-ms 300 --concurrency 50

Or using short options:

cargo run -- -t 192.168.0.1 -T 300 -c 50
