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.
