ProxyJump
By jeltsch on Thu, 05/01/2025 - 07:52Since 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.fi
If you have the same username on both your work and home computers, you can skip the username.
