portmap - The DARPA port to RPC program number mapper
The portmap daemon is a server that converts Remote Procedure Call (RPC)
program numbers into Defense Advanced Research Projects Agency (DARPA) pro-
tocol port numbers. It must be running in order to make RPC calls.
When an RPC server is started, it will tell portmap what port number it is
listening to, and what RPC program numbers it is prepared to serve. When a
client wishes to make an RPC call to a given program number, it will first
contact portmap on the server machine to determine the port number where
RPC packets should be sent.
The portmap daemon must be started before any RPC servers, including mountd
and nfsd, are invoked. Note that if portmap crashes, all servers must be
