You can also detach the sessions, log off from the SSH session and then later log back on, reattach the session and continue from where you left off. It’s really useful for long running tasks that you need to monitor.

There’s a great Red Hat Magazine article showing the basics plus how to set up a .screenrc config file to automatically start sessions or add a status bar to the bottom.

The only other option is to use the nohup command but this does not allow for monitoring progress of a program.

The main problem is that to install screen I need to first install bootstrap but like many people I’m slightly afraid of bricking my Diskstation.

Maybe I’ll add this to the Synology feature request forum in the meantime.

Diskstation Port 80 not responding

On a related note if I enter the admin pages for my Diskstation and enable https connections then my Diskstation no longer listens on port 80, I’ll have to look into this more when I have the time.
