Install RustScan on Ubuntu 24.04

RustScan is a modern, fast, and efficient port scanner written in the Rust programming language. This tool is designed to perform network scanning tasks quickly and with fewer resource requirements. This tutorial explains how to install RustScan on Ubuntu 24.04.

Prepare environment

RustScan requires Nmap. You can read post how to install it.

Install RustScan

Retrieve the most recent version tag of the RustScan release and assign it to a variable:

RUSTSCAN_VERSION=$(curl -s "https://api.github.com/repos/RustScan/RustScan/releases/latest" | grep -Po '"tag_name": "\K[0-9.]+')

Download the RustScan release archive:

wget -qO rustscan.tar.xz https://github.com/RustScan/RustScan/releases/latest/download/rustscan-$RUSTSCAN_VERSION-x86_64-linux.tar.xz

Extract executable to /usr/local/bin directory:

sudo tar xf rustscan.tar.xz --strip-components=1 -C /usr/local/bin

We can check RustScan version using the following command:

rustscan --version

Remove unnecessary downloaded file:

rm -rf rustscan.tar.xz

Testing RustScan

Run rustscan command and provide the IP address of a network device with -a option.

rustscan -a 192.168.0.227 --ulimit 5000

The command scans the device for open ports. The file descriptor limit is set to 5000 to handle a larger number of simultaneous connections.

Output example:

[~] Automatically increasing ulimit value to 5000.
