havn

A fast configurable port scanner with reasonable defaults

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.

Pre-Built

See the pre-built binaries

or, download & install (x86_64 one liner)

shell 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

shell curl https://raw.githubusercontent.com/mrjackwills/havn/main/install.sh | bash

Run

shell havn #[options] Available command line arguments | argument|result| |--|--| | [string] | The address or IP to scan. [default: 127.0.0.1] | |-a | Scan every port, from 1 to 65535, conflicts with -p | |-c [number] | How many concurrent request should be made. [default: 1000] | |-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] | Timeout for each request in milliseconds. [default: 2000] | |-6 | Scan the IPv6 address instead of IPv4, [default: false] |

Examples

```shell

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

Tests

A number of tests will open port 80, this may cause issues if the port is already open on your system

shell cargo test -- --test-threads=1

Build step

x86_64

shell cargo build --release

Cross platform

Using Docker

requires Docker & cross-rs

64bit arm (pi 4, pi zero w 2)

shell cross build --target aarch64-unknown-linux-musleabihf --release

32bit pi (pi zero w)

shell cross build --target arm-unknown-linux-musleabihf --release

Without Docker

64bit arm (pi 4, pi zero w 2)

edit ~/.cargo/config [target.aarch64-unknown-linux-musl] linker = "rust-lld"

shell 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"

rust 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 Untested on other platforms
