jupyter-xprahtml5-proxy 0.3.3

Xpra for JupyterLab

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. You might need to adjust the file launch_xpra.sh to ensure this.

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.
