"Connection refused" usually means you tried to connect to a hostort combination
where nothing is actually listening to the specified port. Whenever you see "connection refused," the first thing to research is whether or not what you're trying to do has a "server side" component (frequently called a "daemon"), and is that component actually running?
I don't know a great deal about rsh and rcp, but a quick Google search on "rshd daemon" reveals that a daemon exists
. You probably need to make sure the daemon is installed and running on your server and try to make a connection, again.
