/**
* Make public the information needed by remote nodes that may wish to

* port mapper (Epmd) and registers the server node's name and port so that
* remote nodes are able to connect.
*
* <p>
* This method will fail if an Epmd process is not running on the localhost.
* See the Erlang documentation for information about starting Epmd.
*
* <p>
* Note that once this method has been called, the node is expected to be
* available to accept incoming connections. For that reason you should make
* sure that you call {@link #accept()} shortly after calling
* {@link #publishPort()}. When you no longer intend to accept connections
* you should call {@link #unPublishPort()}.
*
* @return true if the operation was successful, false if the node was
* already registered.
*
* @exception java.io.IOException
* if the port mapper could not be contacted.
