# On the remote 
jupyter notebook --no-browser --port=8889

# On the client 
ssh -N -f -L localhost:8888:localhost:8889 remote_user@remote_host

# The first option -N tells SSH that no remote commands will be executed and is useful for port forwarding. 
# The second option -f has the effect that SSH will go to background,
# The last option -L lists the port forwarding configuration (remote port 8889 to local port 8888).
