You're not wrong! It's kinda terrifying. Definitely cause to install and use Fail2ban.

When you use ssh-copy-id, you use it from the machine you want to SSH *from* (this is considered your "local" machine). In the scenario you describe, that means you'll run it from your Fedora machine. It sounds like you did that (I assume your server is My_Server), so it should work. I'd need to know more about what error you've encountered.
The comment section isn't the greatest format for support, though. I suggest going over to http://linuxquestions.org, signing up for an account (it's $0), and asking for help there. Lots of people eager to help.
