Re: "connection closed" when running "starcluster ssmaster"

The SSH daemon is responding (and the EC2 security group is not
blocking traffic), which is good.

However, logging onto the master was working a few hours ago and not
anymore, then try to log onto the Grid Engine execution node by using,
for example, "starcluster sshnode rps_cluster node001". If SSHing into
the execution node works, then it is likely to be an issue with the
StarCluster master instance.
