Since OpenSSH 7.3, it has been much easier to connect from the outside to Linux computers inside the UH network.
With older ssh versions, you needed to use a complicated "ProxyCommand", but now it is straightforward:
ssh -J username@markka.it.helsinki.fi username@workpc.pc.helsinki.fiIf you have the same username on both your work and home computers, you can skip the username.
Barrier is an incredible software that lets you use the same keyboard and mouse with different computers without the need for hardware. I have two computers on my desk, and I used to have a hardware KVM (keyboard, video, and mouse) switch, which became obsolete when my computers started to output their video via HDMI. Hence, I have two keyboards on my desk, which is not very ergonomic. I knew about software solutions to this dilemma, but I never had the time to implement them, and I also did not want to pay a subscription fee for this luxury.
