A tool for enabling ssh remote and local port forwarding via SSH and authentication with JupyterHUB application tokens.
- ssh-forwader: the agent responsible for remote ssh forwarding
- ssh-listener: the agent responsible for the local ssh forwarding
This solution is adopted to allow external agents to connect and interact with JupyterLab plugins and extesions, e.g. an HTCondor worker node exposing a service for a Dask client running on a separate JupyterHUB instance
