Jupyter Notebooks

How to use a Jupyter Notebook on the remote server (Gunvor)

1. Open a terminal and log into Gunvor via SSH. Start the notebook in no-browser mode and specify a port (different from any other port on the server):

   jupyter notebook --no-browser --port=[XXXX]

Optional: start the notebook in tmux or screen so that you can later close the terminal while be able to run the notebook (e.g. if you are runing a lon task).

1. Open a second terminal

Create an ssh tunnel to the corresponding server and binding remote port XXXX to local YYYY:

   ssh -f [USER]@[SERVER] -L [YYYY]:localhost:[XXXX] -N

1. You can now enter localhost:[YYYY] in your favorite browser to use the remote notebook!

Attention: The port might be already occupied by another process. In the terminal you will get a warning message. Then the connection in the browser fails! Identify the process number (PID) with ps aux | grep -i notebook or netstat -tlnp | grep [YYYY] and use kill PID to remove process
