Contrary to what portmap's manpage claims, I found that portmap is actually not needed in /etc/hosts.allow.perhaps because it isn't linked against tcpwrapper.

I just noticed Go to Solution 14 Comments LVL 18 Overall: Level 18 Linux 1 Message Expert Comment by:Gary Davis2011-09-26 Connection Refused means that the attempt to connect to the port on the server is failing because nothing is listening on that port. It usually means the process is not running but it could mean that the wrong port is used. It could also be that the server is wrong, of course. Also, things could block the port like a firewall but I don't know if that would result in a Connection Refused. That message means your request reached the server (or some server) but the port is not bound.
