Usage inside an SSH session

[rogerbraun]

I tried using ratatouille inside an SSH session, but the terminal got drawn on the server side, not the client side. The SSH server used is https://github.com/jbenden/esshd, which wraps the ssh module in OTP.

Is it possible to achieve this somehow?

I think it definitely should be possible. The output is written to /dev/tty by default, but it could be made configurable (and set to another file) if needed. It's a matter of making sure the output is written to the right file and that it's redirected correctly to your ssh client.

But I think it works in general via ssh. For example, I can start up openssh-server locally, ssh into the machine, and run one of the examples:

$ ssh ndr@127.0.0.1
Last login: Mon Apr  1 16:07:27 2019 from 127.0.0.1
ndr@localhost ~/c/ratatouille> mix run examples/counter.exs 

(That renders the example in my client session.)

So I wonder if this is specific to Erlang ssh or your application. Could you describe how it works a bit more?

For example, is it an Erlang/Elixir client, openssh client, or something else? Also, does the client start a new Erlang VM process with ratatouille, or is it already running when you connect? Is there a PTY connected?

If you have an example that I can run, I'd be happy to test it out here.

I'm late to this party, but if you don't have a display server running echo $DISPLAY (returns nothing on the remote host) or SSH is not configured for X11 forwarding it won't work but it's not a limitation of Ratatouille.
