Port Scanner

A fast, concurrent port scanner written in Rust that intelligently detects common services and protocols with a focus on blockchain and web services.

Features

• 🚀 High Performance:

  • Async/await based concurrent scanning
  • Configurable concurrency limits
  • Non-blocking I/O operations

• 🔍 Smart Service Detection:

  • Ethereum JSON-RPC nodes (ports 8545-8549)
  • HTTP/HTTPS web servers with server fingerprinting
  • REST/GraphQL API endpoints
  • Debug/Remote ports
  • Generic TCP services

• 🌐 Network Support:

  • IPv4 and IPv6 addresses
  • Hostname resolution via Google DNS (1.1.1.1)
  • Fallback DNS mechanisms
  • Custom port range scanning

• 📊 User Experience:

  • Real-time progress bar with ETA
  • Colored terminal output
  • Detailed service information including:
    • Protocol detection
    • Service identification
    • Version information (when available)
    • Response headers analysis

• ⚙️ Configuration Options:

  • Port range selection (--start-port, --end-port)
  • Connection timeout (--timeout)
  • Concurrent scan limit (--concurrent-limit)
  • Custom service detection rules

Prerequisites

• Rust 1.56 or higher
• Cargo package manager

Installation

From Crates.io (Recommended)

cargo install port-scanner

From Source

git clone https://github.com/morteza-shojaei/port-scanner.git
cd port-scanner
cargo build --release

Usage

Basic usage:

port-scanner-rs--target <host>

Advanced options:

port-scanner-rs--target <host> --start-port 1 --end-port 1024 --timeout 1000 --concurrent-limit 100

Examples

Scan a specific IP:

port-scanner-rs--target 192.168.1.1

Scan a domain:

port-scanner-rs--target ethereum.org

Scan specific port range:

port-scanner-rs--target 192.168.1.1 --start-port 8545 --end-port 8549

Security Considerations

• Always ensure you have permission to scan the target system
• Be aware that aggressive scanning may trigger IDS/IPS systems
• Consider rate limiting when scanning production systems
• Some networks may block or flag port scanning activities
