portmap

rpc.portmap [options]

NFS/NIS command. RPC program number to IP port mapper. portmap is a server that converts RPC program numbers to IP port numbers. It must be running in order to make RPC calls. When an RPC server is started, it tells portmap which port number it is listening to and which RPC program numbers it is prepared to serve. When a client wishes to make an RPC call to a given program number, it first contacts portmap on the server machine to determine the port number where RPC packets should be sent. portmap must be the first RPC server started.

Options

-d

Run portmap in debugging mode. Does not allow portmap to run as a daemon.
