Running jupyter notebook from web server on ipad localhost

Question

I'm using Blink on my iPad Pro to SSH to my DigitalOcean Ubuntu web server and run Jupyter Notebook.

I can SSH just fine, and can run Jupyter Notebook fine as well. I get the usual Jupyter Notebook url http://localhost:8888/?token-12345 but when copy-pasting this url in my chrome browser on my iPad, I get he error message 'this site can't be reached'.

Anyone knows how to fix that? Is SSH tunnelling part of the solution? What command(s) should I run?

Answer 1

There are multiple ways to do that:

• SSH tunnel / port forwarding. You may need a standalone app to establish a tunnel (this one, for example), and then connect to your server in browser using localhost and mapped port.
• Public server. You can make your server accessible publicly (more details here), but beware that you may also need to configure a valid SSL certificate to connect to your server via HTTPS, or otherwise Jupyter's kernel will not be able to connect in any iOS browser. Here is a step-by-step guide on how to configure a self-signed certificate that will work on iPad: https://juno.sh/ssl-self-signed-cert/

Finally, once you get it working in Chrome/Safari, you may consider using an app that I've developed instead of browser, it's called Juno and it's a Jupyter Notebook client for iPad: https://itunes.apple.com/app/juno-jupyter-notebook-client/id1315744137

It does require an in-app purchase to connect to an arbitrary server, but you can launch a bunch of introductory notebooks for free out of the box, without any configuration.
