When setting up a distant observatory it’s good to do a few final checks that otherwise require a site visit to fix. Although you would normally connect remotely via SSH to your observatory PC, the real backup in case the operating system gets messed up is the Intel vPro chipset, the Intel Manageability Engine, that allows you to remotely start your Clonezilla USB stick or CD you left in the PC to reimage with the complete drive image on the on-site external HDD you copied with Clonezilla before shipping. If this system is somehow goofed up, it will require a site visit if the PC has a major software problem.
Final checks before shipping remote sensing vPro PC
- Verify Intel ME web server from the remote PC:
- Verify Intel ME web server from laptop. This will require you to port forward SSH on the last hop (if you’re not using VPN). Be sure these ports are not exposed to the public Internet!
If you can get to the web interface, you can choose which drive to boot from. This is not quite enough to reimage, but if you kept two installed operating systems with boot-flagged partitions on each drive, it can save you.
However it’s best to go the rest of the way to verify you can connect using:
- without RealVNC
You will be able to see and get into BIOS during boot, and otherwise get graphical remote control as if you were sitting at the PC.
Final physical PC checks
Finally on the hardware side be sure the CPU fan hasn’t become loose from the CPU, that no wires are near the fan blades, and every cable is still plugged snug into the motherboard.
