|(networking)||portmapper - A server that converts TCP/IP protocol
port numbers into RPC program numbers. It must be running
in order to make RPC calls.|
When an RPC server starts, it tells portmap the port number it is listening on and what RPC program numbers it serves. Before a client can call a given RPC program number, it must contacts portmap on the server machine to determine the port number to which RPC packets should be sent.
