There are many, many networking and originally UNIX tools tricks (e.g. SSH) you can show to the poor people supporting industrial networks/ hardware. I have written some of my tricks down in this OrgPage: https://www.orgpad.com/s/UHUor4 https://www.orgpad.com/s/UHUor4 there are screenshots for Linux and Windows for some things related to SSHFS, SOCKS Proxy and more. Click units with shadows to open them. From time to time, I update it to reflect new tricks. This knowledge saved at least 2 companies hundreds if not thousands of euros in on-site support, hardware and other expenses. Funnily, while these things are quite hacky, they tend to work better than most of the dedicated hardware I have seen in practice, while keeping you/ the technician/ engineer in control. With any kind of working infrastructure, you can estimate how good your solutions are because you don't get called at random times and from monitoring/ explicit contact you just see/ hear the things work fine.
