I'm trying to connect to jupyter notebook running on my remote server. The code below has been working fine for days to forward the jupyter notebook running on the port on my ubuntu server to my mac. It stopped today. Does anyone know what the issue might be? Also does anyone know how I can just open the port on my ubuntu server so I wouldn't need the code below?

code:

ssh -L 8000:localhost:8888 [email protected]

Update:

code:

jupyter notebook --no-browser --port=8889

Message:

I encounter the same problem time to time. You can try restarting your remote jupyter server (the link contains information to kill existing server and start a new one). Or try a different port number. BTW please share the exact error you face with.

Change "ipython" with "jupyter" and make sure jupyter is installed both on remote machine and your machine.

ipython notebook --no-browser --port=8889

jupyter notebook --no-browser --port=8889

The issue seems to be that I needed to type localhost:8888 in to the browser on my local machine. I had been typing in the port I opened the jupyter notebook server on, on my remote machine so localhost:8889. Example 

jupyter notebook --no-browser --port=8889

followed by 

ssh -N -f -L localhost:8888:localhost:8889 [email protected]

bang head here.

This is because you have already opened another Jupyter notebook using port 8888 on your local machine. So solution is simply choosing a different port number, e.g. 8890 or else except 8888 in your case.
