I often seem to find myself in this scenario: - I SSH into Server A using my personal key - I SSH into Server B using my personal key I find files I need on B that I need to transfer from B
Usually the files are quite small so I'll just transfer them to my own PC as an intermediary. But I now need to transfer about 30GB from A to B so it seems like the right time to find a better way.
I don't really want to have to give A permanent access to B (albeit I can always delete the key later, it seems like the sort of thing that would get forgotten).
