How to obtain the token of a running Jupyter server

TL;DR

SSH into the remote server and run:

jupyter server list

This will show the list of running Jupyter servers together with the token.

Note that it is possible to create a configuration file for Jupyter, which may overwrite certain options, e.g. specify a password instead of a token, in which case no token would be listed by the command above.

Breakdown

  1. jupyter can be run as a system command, followed by the specific subcommand and options.
  2. Use jupyter --help to obtain a detailed list of options. At the time of writing this the available subcommands are listed at the bottom of the help as Available subcommands: .....
  3. The token obtained here is often requested when connecting remotely to the Jupyter server, as explained in this note.
