jupyter-xprahtml5-proxy

Integrate Xpra in your Jupyter environment for an fast, feature-rich and easy to use remote desktop in the browser.

Requirements

• Python 3.6+
• Jupyter Notebook 6.0+
• JupyterLab >= 3.x
• jupyter-server-proxy >= 3.1.0

This package executes the xpra command. This command assumes the xpra command is available in the environment's $PATH.

Security

Xpra supports password and encryption.
Both are NOT required, if you can trust everyone, who can log in to the host where your JupyterLab is running. (incl. jupyter-server-proxy, jupyter-xprahtml5-proxy and Xpra-HTML5)

BUT (!!!)
if you are on a multiuser system, where you CANNOT trust everyone,
you must(!) ensure that your Xpra session is secured by at least a password.

Currently this requires

• that jupyter-server-proxy includes this pull request and
• you use jupyter-xprahtml5-proxy with a version number >= 0.3.0 (not on pypi)

Xpra

Xpra is an open-source multi-platform persistent remote display solution for forwarding applications and desktop screens. It allows you to run X11 programs, usually on a remote host, and direct their display to your local machine.
Best of it. It is fast, fast, fast and comes with a build-in html5 client to allow remote.

Jupyter-Server-Proxy

Jupyter-Server-Proxy lets you run arbitrary external processes (such as Xpra-HTML5) alongside your notebook, and provide authenticated web access to them.
