If your attempt to recreate ssh tunnel ends with an error:

bind: Address already in use
channel_setup_fwd_listener_tcpip: cannot listen to port: 8888
Could not request local forwarding.

kill the process with the port binding:

lsof -ti:8888 | xargs kill -9

1. On the remote server start jupyter notebook with non-default port and with no-browser option:

jupyter notebook --no-browser --port=8888

2. On the local server run ssh with next options:

ssh -N -f -L 8888:localhost:8888

3. In your browser open http://localhost:8888
