How can I run a Jupyter Notebook on the server and access it over the internet?

  1. Create a conda environment with jupyter notebook package installed.
  2. Activate that environment.
  3. Run jupyter notebook --generate-config
  4. It will say the configuration file for your account. Edit the configuration file and add the following two lines. (They are originally commented out as given below.)
    # c.NotebookApp.allow_origin = ''
    # c.NotebookApp.ip = 'localhost'
    c.NotebookApp.allow_origin = '*'
    c.NotebookApp.ip = '0.0.0.0'
    
  5. Save the configuration file. You should still be in the conda environment.
  6. Run the jupyter notebook. jupyter-notebook --no-browser
  7. You will see a URL like this http://SOMETHING:8888/tree?token=abc123def456
  8. Type the following address into your PC browser http://aiken.ce.pdn.ac.lk:8888/tree?token=abc123def456
