None Auth Method

[gigamonster256]

I have been planning an “Intro to Linux” workshop for the students at my university and want a way for students to easily be able to tinker with the Linux command line and basic tools. I was looking for tools to spin up and login to ephemeral containers with ssh and ContainerSSH seems to fit my needs perfectly.

I spun up an instance on a docker host and it works great, however I was wondering if a “None” authentication method would be desired to be implemented here. I don’t have much of a use for authentication and authorization of my students, and id like the login process to be extremely simple given this will be a lot of their first times using the command line.

I’ve seen other ssh frontend based framework/libraries use a KeyboardInteractiveHandler that just automatically grants authorization without presenting any questions and I believe such a method could be implemented in ContainerSSH rather easily.

something like

auth:
  none:
    enable: true

would this functionality be something desired for ContainerSSH, or something best kept in a fork? I’d be totally willing to PR anything I come up with and take feedback about implementation/config details.

That seems like a good idea, I guess there are many people that would like to use this, though for your case I hope you consider your network and docker secure enough :)

Our ssh library supports the NoAuth authentication method, so this should be a trivial thing to implement.
