This is a very different error from the one you show later:

The first error ("Permission denied") suggests that the isntance does
not accept your key for the 'fedora' user.  Perhaps get the console
output and see if it says anything about installing the keypair.

You also want to actually run the ssh command with '-vvv' and copy the
_full_ output for that error.

The second error ("Connection timed out") suggests that the security
group does not allow SSH.

I don't quite see how you get both of these errors on the same instance.
ec2-54-81-79-177.compute-1.amazonaws.com is currently accepting SSH from
linux-lab.cs.stevens.edu, so I would think the error would be the first
one.

Check the permissions on your private ssh key, too.
