Some linux instances require you to log in as a non-root user.  The user
to use may differ depending on the AMI.  Review the information about
the AMI / documentation provided by whoever created the image to find
out which user that might be.

You probably want to have a passphrase on your ssh key, since you are
storing it on a shared system (ie linux-lab).  If you have no
passphrase, though, then ssh shouldn't prompt you for one, so it'd be
strange if this sequence of actions worked for OmniOS.

Your favorite internet search engine and/or AWS online documentation
should be able to help you here.
