Many thanks for your time and detailed answer, I appreciate it.
I follow your indication and everything goes well until I complete step 11.
Once the jupyter notebooks are up and running and I get the URL with token displayed on bash (as on the post), I am unable to paste the next line code on my bash(it accepts no more text)
I try entering a new command by right clicking on the bash (mac), so I can run and enter the new command in the shell.
ssh -NfL 9999:localhost:8888 ec2
The result is a new bash opens up and I am informed and I am informed I am logged out, it ends with [Process Completed]
I found (finally!) how to successfully connect from my bash to EC2 and then open Jupyter Notebooks.
This tutorial explains it well.
However, I am suprised once I on Jupyter Notebooks, I can only see a folder named src . I cannot navigate through my computer and find the notebooks I wish to run.
Does it mean I have to upload them prior running them?
Many thanks for your support.
