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.
If iLO/DRAC is present, use them. IF not, you can equip your host by so called IP-KVM. If your host is virtual, probably you can access it via some kind of VNC.
With any server, if the service fails you lose access. If SSH is failing, I'd be concerned about configuration mistakes or hardware issues. Adding another service isn't a solution for this problem.
If your server is real hardware, consider setting up an external serial console and using that as the kernel's console interface. If its a VM, the hypervisor's console feature.
If you just need to view the console messages, you can use netconsole to send them to a syslog server running on your windows box.
