rustscanr

rustscanr is a simple async TCP port scanner written in Rust. It is designed to quickly scan port ranges on target hosts, providing fast and efficient network reconnaissance.

Features

• Blazing fast asynchronous TCP scanning
• Customizable port ranges and concurrency
• Configurable connection timeout
• Easy to use CLI interface

Installation

cargo install rustscanr

Or clone and build manually:

git clone https://github.com/yourusername/rustscanr.git
cd rustscanr
cargo build --release

Usage

rustscanr <HOST>

Arguments

• <HOST> - Hostname or IP to scan (e.g. example.com or 192.168.1.10)

Options

• -s, --start <START> - Start port (inclusive) [default: 1]
• -e, --end <END> - End port (inclusive) [default: 1024]
• -c, --concurrency <CONCURRENCY> - Concurrency: how many ports to check in parallel [default: 100]
• -t, --timeout-ms <TIMEOUT_MS> - Timeout per connection attempt in milliseconds [default: 300]
• -h, --help - Print help

Examples

Scan default port range (1-1024) on a host:

rustscanr example.com

Scan a specific port range with custom concurrency:

rustscanr 192.168.1.10 -s 80 -e 8080 -c 200

Scan with custom timeout:

rustscanr example.com -s 1 -e 65535 -t 500
