What is this app?

This is an attempt at a port scanner written in Rust as a hobby project. I thought it would be a fun little tool to make while also brushing up on writing CLI apps now that I have more experience programming.

The common ports collection was acquired by running the following command

awk '$2~/tcp$/' /usr/share/nmap/nmap-services | sort -r -k3 | head -n 1000 | tr -s ' ' | cut -d '/' -f1 | sed 's/\S*\s*\(\S*\).*/\1,/'

How to install the app

To install this app with cargo installed just run

cargo install rtcps

If you are on a Debian based system and want to install the binary through your package manager you can download the provided .deb file

If you would like to build a binary from source you can run release.py

How to use the app

You can build the app with Cargo installed by running the following command in the project directory.

cargo build --release

Then it can be started by running

cargo run -- [ip_address_to_scan]

The supplied IP address can be either Ipv4 or Ipv6

By default if only an IP address was supplied it will attempt to scan all of the ports. You can supply a range of ports to scan like so.

cargo run -- 127.0.0.1 1-65535

If you would only like to scan the top 1000 most common ports you can run

cargo run -- 127.0.0.1 -c

Benchmarking

If you wanna run the benchmark it is backed by Criterion.rs, all you have to do is run

cargo bench

If you want to generate a flamegraph run

cargo bench --bench all_port_bench -- --profile-time=5

Unsupported targets

Currently Linux musl support is lacking and it won't compile due to clap's derive feature not being supported on musl. An alternative cli struct is being planned for use on musl system.
