shellinabox

I need to give shell access to my Linux students and the most easy way is by using shellinabox. They can also install Linux at home, but still it is more fun when you use Linux in a multi-user environment. It is also easier for me to assign and evaluate homeworks.

Install

• First install ds and wsproxy:

  • https://github.com/docker-scripts/ds#installation
  • https://github.com/docker-scripts/wsproxy#installation

• Then get the shellinabox scripts from github: ds pull shellinabox

• Create a directory for the shellinabox container: ds init shellinabox @shell1

• Fix the settings: cd /var/ds/shell1/; vim settings.sh

• Build image, create the container and configure it: ds make

Access the website

• Tell wsproxy to manage the domain of this container: ds wsproxy add

• Tell wsproxy to get a free letsencrypt.org SSL certificate for this domain (if it is a real one):

  ds wsproxy ssl-cert --test
  ds wsproxy ssl-cert
  

• If the domain is not a real one, add to /etc/hosts the line 127.0.0.1 shell1.example.org and then try https://shell1.example.org in browser.

Other commands

ds shell
