I'll soon have 30 boxes being used at one of our workplaces under my control and a few other groups (not as large) in separate locations.
These boxes are behind a router and will occasionally need support/cleaning/fixing (you probably get the idea).
I had planned to set up port forwarding to a single box in every location/group, SSH into that box then SSH into the rest of the computers locally from that box.
I'm 300 miles away from the actual machines and will only be with them physically about once a month at most.
Am I doing the correct thing? What is the best way to handle this securely?
I don't think I will require to remote desktop but any suggestions regarding that would be interesting to hear.
I'm fairly confident with Linux systems, I am not a very confident system administrator but I do often throw myself in the deep end and get to grips with things relatively fast. Any help or advice/tips regarding administration like this would be deeply appreciated.
