If your servers are &#x27;permanent&#x27;, then give them a short hostname and put them in your .ssh&#x2F;config and DNS (or hosts file). &#x27;ssh cron&#x27; or &#x27;ssh archive&#x27; and connecting directly is quicker than going through a dialogue, or using an index number and having to remember which is which (or worrying about the index number changing when you refresh).<p>This tool would be good for temporary or autoscaling instances, though.
