I have a Slackware Linux server that doesn't have a monitor. It doesn't run any GUIs.

Is there a way to remotely access the screen? I always use SSH, but there are times where the SSH services fails and I can't do anything (nor even tell what the problem is).

I use Teamviewer from my Windows computer to other PCs, but is there anything I can use to remotely view this from a Windows machine?

I also want to see what it's doing at boot, before the SSH service starts.
