How to disable terminals in TLJH

See original GitHub issue

Hi,

I was trying to disable the terminals as described in Custom jupyterhub_config.py snippets but for some reason it did not work for me.

I created a python file named jupyterhub_noterminals_config.py in /opt/tljh/config/jupyterhub_config.d with file permissions -rw-r--r-- (owner is root) and containing the single line: c.NotebookApp.terminals_enabled = False

When I reload the configuration with sudo tljh-config reload the terminals are still visible for existing and new users. The terminals are also enabled for all users when I reboot. I found no obvious error message in the JupyterHub logs.

The only way I managed to disable terminals was to change both boolean parameters in line 1282 in /opt/tljh/user/lib/python3.6/site-packages/notebook/notebookapp.py from True to False and then reboot.

What did I miss?

Thank you in advance.

ps1: installed TLJH with bootstrap.py (commit 8ec3fab) ps2# Related issue in jupyterhub

Hi,

Thanks to your hint I found a solution:

I enabled the terminals again in order to execute the following commands in the terminal of the administrator user in TLJH
I searched for the config paths using the command jupyter --paths (mentioned in this issue)
I generated a config file jupyter_notebook_config.py using the command jupyter notebook --generate-config (described here). This file is generated into the admin’s .jupyter directory (listed first in the config paths)
I enabled the line c.NotebookApp.terminals_enabled = True in the generated jupyter_notebook_config.py
I copied this file using sudo to /opt/tljh/user/etc/jupyter (listed second in the config paths) and changed it’s entry from True to False
Reboot the server (is there a better way?)
Now the TLJH administrator user has access to a terminal and all normal users have no terminal

@woschmid awesome! Glad you have that working 😃

Starting and stopping a user’s server should work instead of having to reboot the machine, since notebook server reads the config on each start.

I’m going to close this now since we’ve figured out what works for you. Thank you for posting a detailed solution for the next person who finds this issue! ❤️
