I'm afraid you'll have to ask the EC2 folks - you probably need something to
get through their firewall.
If you just try "ssh ec2-174-129-183-64.compute-1.amazonaws.com hostname", does
that work? I would just try to make that work first - once it does, so should

I'm trying to add EC2 instances into my local cluster with openMPI. So far
openMPI works well on the local cluster, and I have set up passwordless SSH
between the local cluster and the Amazon EC2 instance.
Howver, when I add the public DNS into a file (defaulthostfiletest)
comp1 slots=2
