havn
Description
havn
- ˈheɪvən
|| "HAY" + "vuhn"
- is a lightweight self-contained port scanning application written in Rust,
using asynchronous Tokio multithreading to deliver fast and reliable results.
With sensible defaults and configurable options, users are able customise the scanning process according to their needs.
It is designed and built to be compatible with multiple platforms, including Docker, and has a binary size of less than 1mb.
Download & install
Cargo
Published on crates.io, so if you have cargo installed, simply run

Docker
Published on Docker Hub and ghcr.io,
with images built for linux/amd64
, linux/arm64
, and linux/arm/v6
via Docker Hub
docker run --rm -it mrjackwills/havn:latest #[options]
via ghcr.io
docker run --rm -it ghcr.io/mrjackwills/havn:latest #[options]
❗Caution: To scan the Docker host itself, you must grant access by including the option:

Pre-Built
See the pre-built binaries
or, download & install (x86_64 one liner)
wget https://www.github.com/mrjackwills/havn/releases/latest/download/havn_linux_x86_64.tar.gz &&
tar xzvf havn_linux_x86_64.tar.gz havn &&
install -Dm 755 havn -t "${HOME}/.local/bin" &&
rm havn_linux_x86_64.tar.gz havn
or, for automatic platform selection, download, and installation (to $HOME/.local/bin
)
One should always verify script content before running in a shell
curl https://raw.githubusercontent.com/mrjackwills/havn/main/install.sh | bash
Run
havn #[options]

argument | result |
---|---|

-c [number] |
How many concurrent request should be made. [default: 1000 ] |
-m |
Monochrome mode - won't colourize the output [default: false ] |
-p [number / string] |
Inclusive port range to scan, accepts either a range: -300 , 101-200 , or a single port 80 , conflicts with -a [default: -1000 ] |
-r [number] |
Retry attempts per port. [default: 1 ] |
-t [number] |

Examples
# Scan github.com using the default settings
havn github.com
# Scan default address [127.0.0.1], all ports [1-65535],
# 2048 concurrent requests, 500ms timeout, 0 retries, IPv4
havn -a -c 2048 -t 500 -r 0
# Scan www.google.com, ports 10-600,
# 500 concurrent requests, 3000ms timeout, default retries [1], IPv4
havn www.google.com -p 10-600 -c 500 -t 3000
# Scan www.digitalocean.com, ports 1-100
# default concurrent requests[1000], 1000ms timeout, and use IPv6 address
havn www.digitalocean.com -p -100 -t 1000 -6
# Scan www.bbc.com, port 443 only
# default concurrent requests[1000], default timeout[2000ms], 6 retries, IPv4
havn www.bbc.com -p 443 -r 6
Todo
- Scan UDP ports, currently only TCP
- allow multiple addresses/IPs to be scanned
- monitor response times to automatically modify request settings
- configurable option to disable second-pass scan
- debug option to display more verbose output
- improve windows performance
- publish to npm
Tests
A number of tests will open port 80, this may cause issues if the port is already open on your system
cargo test -- --test-threads=1
Build step
x86_64
cargo build --release
Cross platform
Using Docker
64bit arm (pi 4, pi zero w 2)
cross build --target aarch64-unknown-linux-musl --release
32bit pi (pi zero w)
cross build --target arm-unknown-linux-musleabihf --release
Windows x86_64
cross build --target x86_64-pc-windows-gnu --release
Without Docker
64bit arm (pi 4, pi zero w 2)
edit ~/.cargo/config
[target.aarch64-unknown-linux-musl]
linker = "rust-lld"
rustup target add aarch64-unknown-linux-musl
cargo build --target aarch64-unknown-linux-musl --release
32bit pi (pi zero w)
edit ~/.cargo/config
[target.arm-unknown-linux-musleabihf]
linker = "arm-linux-gnueabihf-ld"
sudo apt update && sudo apt install gcc-arm-linux-gnueabihf -y
rustup target add arm-unknown-linux-musleabihf
cargo build --target arm-unknown-linux-musleabihf --release
