There are some services that I don’t want to run all the time which makes me not want to open a port for it. One good example of this is Jupyter Notebooks. Therefore, what I sometimes do is run it locally and forward the port so that another machine can access it.

Example command:

ssh -L 8888:localhost:8888 -N 192.168.0.2

The -L flag allows you to specify the localsocket:host:remotesocket.

-N makes it so that it doesn’t execute any additional commands

Then finally you put the address of the machine you wish to connect to.
