I have what I fear may be a stupid #Linux question...
If I set up an ssh key, upload it to the server, and then disable password login...
When I want to ssh from another machine? How would I then upload that key to the server?

@hellomiakoda each machine you connect from will need that private key, then ssh user@host -i /path/to/key.

Or at least thats how ive seen it done before, there might be better solutions
