sshbox

sshbox

A very simple SSH server that "boxes" you into a sandbox environment using uLinux box utility for creating lightweight sandboxes -- or any process you want to use as a "sandbox".

Can also be used as a regualr SSH server 😉

Based on this example

Features

sshbox supports:

• Authorized Key for authenticating sessions
• Github for authenticating sessions
• Sandboxing by running box or docker to sandbox sessions

Install

If you have a Go development environment setup with $GOPATH/bin/ in your $PATH the following will just work™ 😀

go get -u git.mills.io/prologic/sshbox

Otherwise you can build from source using git (You still need the Go compiler):

git clone https://git.mills.io/prologic/sshbox.git
cd sshbox
make

Prebuilt Binaries

There are prebuilt binaries I publish regularly to the Releases page you can download and install. Example:

wget https://git.mills.io/prologic/sshbox/releases/download/0.0.2/sshbox_0.0.2_linux_amd64.tar.gz
tar xvf sshbox_0.0.2_linux_amd64.tar.gz

Usage

Run an SSH server on the default port listening port ;2222, authorising users with an authorized_keys file and sandbox user sessions using box with an Alpine Linux container:

sshbox ~/.ssh/authorized_keys 'box run alpine /bin/sh'

Same thing but authorize users via their Github SSH Keys:

sshbox -g /dev/null 'box run alpine /bin/sh'

NOTE: Only tested on uLinux.
