Getting remote access to jupyter notebook

[Anthony Wertz]

I almost always use a tunnel, configured similar to what Predrag specified.

You can greatly simplify this process by storing these proxy configurations
in your SSH config file, e.g. on my laptop I can put in ~/.ssh/config (on
macOS, similar on *nix, you're on your own on Windows):

Host bash
   Hostname bash.autonlab.org
   UseKeychain yes

Host gpu2
   Hostname gpu2
   ProxyCommand ssh bash exec nc %h %p
   UseKeychain yes

And with that I can forward a port from GPU2 as if I could directly see the
machine:

ssh -L <A>:localhost:<B> gpu2

That being said, I proxy through my workstation which is substantially
beefier than bash, so using bash as the middle-man might be what's slowing
things down (Predrag can comment on that, there might be better gateways to
use). I generally have no issues forwarding jupyter notebooks or anything
else this way, and (for me at least) it's usually snappier than running a
browser in X2go (might be the mac client or my failure to configure things
properly :-))
