   This sets up the remote shell for rooton the AIX node,such that root can
 | 
						|
   login using with no password. The default is /bin/rsh and
 | 
						|
   /bin/rcp but can be overriden by setting the useSSHonAIX attribute in the 
 | 
						|
   site table to yes, in which case we will use ssh/scp.
