SuperTunnel is a tool I’ve often wanted for keeping SSH tunnels alive – mostly by just watching for when a tunnel dies and starting a new one. Its a handy way to re-connect after some temporary loss of connection like walking to a meeting, or going through a real tunnel on the train.

There are lots of other ways you can convince an SSH connection to stay open – and don’t worry, you can use those with supertunnel as well – it uses plain ssh under the hood.

I use supertunnel to open port forwarding to my jupyter notebooks when I’m working on a remote machine.

You can install supertunnel via pip:

pip install supertunnel

Then, use it like this:

st jupyter --auto
