Force Jupyter Notebook *not* to open a web browser

I'm running Jupyter notebooks (Python 3) on a remote cluster that I'm connected/tunneled to over SSH.

Jupyter's default behavior is to try to open the dashboard in a web browser when it launches -- aparently (I only just updated), at some point they switched to the Python 3 webbrowser library for this.

According to webbrowser's documentation:

text-mode browsers will be used if graphical browsers are not available or an X11 display isn’t available.

This is exactly what happens. I run jupyter notebook, webbrowser launches elinks, and my one-time authentication token gets eaten, preventing me from connecting to the notebook.

Jupyter isn't configured to use a browser -- c.NotebookApp.browser is commented out in my config -- and running BROWSER="" jupyter notebook doesn't help either.

How can I force Jupyter not to open any browser?

If you use jupyter lab or other jupyter tooling, the browser might still open.

To always disable the browser for all jupyter commands, edit your default config at:

~/.jupyter/jupyter_notebook_config.py

And add the following lines:

c.NotebookApp.open_browser = False
c.LabApp.open_browser = False
c.ServerApp.open_browser = False
c.ExtensionApp.open_browser = False

Source:

From Jupyter help pages:

--no-browser
    Prevent the opening of the default url in the browser.
    Equivalent to: [--ServerApp.open_browser=False --ExtensionApp.open_browser=False]

jupyter notebook --generate-config

Then edit ~/.jupyter/jupyter_notebook_config.py and Add

NotebookApp.open_browser = False

You can achieve this by specifying --no-browser: 

$ jupyter notebook --no-browser

I also recommend that you specify the port you want to use:

jupyter notebook --no-browser --port= <port_number>

ie:

$ jupyter notebook --no-browser --port=8888

You have to keep in mind that when you do this, jupyter will provide you with a token on the console, token that the server will ask you when connect remotely through the browser.

If you want to simplify this procedure, you can set a password that is easier for you to remember. To do this, you can run in a console:

$ jupyter notebook --generate-config

and later:

$ jupyter notebook password

This last command will ask you for the password that you wish to use to enter remotely.
