RustScan

RustScan is a modern port scanner written in Rust that finds open ports extremely fast and automatically pipes the results into Nmap for deeper analysis. It combines the speed of modern programming with Nmap's detailed scanning capabilities.

RustScan focuses on speed, finding open ports in seconds using Rust's concurrency model. Nmap provides detailed service detection and OS fingerprinting but is slower. RustScan automatically passes discovered ports to Nmap.

RustScan can run standalone for port discovery, but its key feature is automatic Nmap integration. It pipes discovered ports into Nmap for service detection, combining speed with depth.

Yes, RustScan is significantly faster for port discovery. It can scan all 65535 ports in seconds. Nmap's port scanning is slower but provides more detailed information about each port.

Install RustScan using: sudo apt install rustscan on Kali Linux. On other systems, install via cargo: cargo install rustscan, or download from the GitHub releases page.

Run rustscan -a target --range 1-65535 to scan all ports. Use rustscan -a target -- -sV to pipe results into Nmap for service detection.

Common commands include: rustscan -a target (basic scan), rustscan -a target -- -sV (with Nmap version detection), rustscan -a target -b 1000 (custom batch size), rustscan -a target -p 22,80,443 (specific ports).

The -b flag sets the batch size, controlling how many packets RustScan sends simultaneously. Higher values increase speed but may cause packet loss. Start with the default and increase if needed.

Masscan is faster for internet-wide scanning (10M pps) but lacks Nmap integration. RustScan offers automatic Nmap piping for service detection. Use Masscan for huge networks; RustScan for targeted scans with Nmap analysis.

RustScan itself is legal software. However, scanning networks without permission from the owner may violate laws. Always obtain written authorization before scanning networks you don't own or manage.

RustScan finds ports in seconds, then Nmap analyzes them. Running Nmap with -p- for all ports takes minutes; RustScan does it in seconds. The combination saves time while providing the same depth of analysis.

The --no-nmap flag runs RustScan without automatic Nmap integration. This is useful when you only need port discovery or want to use a different tool for service detection.

Use the -- separator to pass flags to Nmap: rustscan -a target -- -sV -sC. Everything after -- is passed directly to Nmap.

RustScan doesn't perform service detection or OS fingerprinting without Nmap. It's also newer with a smaller community. For comprehensive analysis, always pipe results to Nmap.

Use the -p flag: rustscan -a target -p 22,80,443. This scans only the specified ports instead of all 65535.

RustScan's adaptive learning adjusts scanning speed based on network conditions. It automatically slows down if it detects packet loss, ensuring accurate results without manual configuration.

A basic RustScan scan of all 65535 ports completes in 3-10 seconds. With Nmap integration, the total time depends on the number of open ports found and Nmap's scanning depth.

Yes, RustScan runs on Windows, Linux, and macOS. Install via the GitHub releases page or cargo (Rust package manager) on any supported platform.
