I want to access a computer, say machine A which is based in my university's network. However, this computer is only accessible via the internal network of the university, so I can not use SSH to this computer from home directly.
Here's what I do now:
Log in to a different university machine, say machine B
(This machine B is accessible via SSH from my home computer.)
Use SSH on B to connect to A.
Is there a way to do that faster? Using only one ssh command.
