PORTMAP(NADM)                                  UNIX System V



     Name
          portmap - DARPA port to RPC program number mapper


     Syntax
          /etc/portmap


     Description
          portmap is a server that converts RPC program  numbers  into
          DARPA protocol 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.

     Notes
          If portmap crashes, all servers must be restarted.
