If you're getting a 'no route to host' error, that typically means you
can't ping the host either.
connection refused typically means that the pmcd isn't listening on
You can verify that it is listening on the network (on the server half)
with "netstat -na | grep LISTEN | grep :4321 " where port 4321 is the
default pmcd port number.
