Here are the things that have kept sshd from working on new installations for me in the past.  I don't know which, if any, would apply to Fedora 20 today.

1) As I remember, some ssh setups come configured so that they will only talk to localhost (though that may be ftp, not ssh).

2) For some reason, I commonly had a problem with SeLinux blocking ssh.  I turn it off.

3) Sometimes I forget to set up the rsa keys and nothing will authenticate.
