I have managed to get NoMachine running on my local network to access my headless server running Ubuntu Desktop 20.04 using the NoMachine client on my Mac Book Pro (running High Sierra)
I would like to be able to access Ubuntu Desktop remotely, however, I don’t want to simply open port 4000 on my router as this seems a security risk.
I previously used [NX derivative] to remotely access Ubuntu Desktop (16.04) over the internet with an SSH key, so I felt this setup was safer (?)
How can I use NoMachine to remotely access Ubuntu Desktop “securely” using an SSH key ?
