PORTMAP(8C)                     Domain/OS BSD                      PORTMAP(8C)



NAME
     portmap - daemon to map RPC (Remote Procedure Call) program numbers to
     DARPA protocol port numbers

SYNOPSIS
     Normally started by /etc/rc.nfs.  See description below.

DESCRIPTION
     The /etc/rc.nfs script normally starts up /etc/portmap, if the file
     /etc/daemons/portmap exists. (Note that it is the existence of
     /etc/daemons/portmap that causes /etc/rc.nfs to invoke /etc/portmap.  The
     contents of the file are irrelevant.)

     The portmap server daemon runs on a server host and directs data
     transmissions from client hosts to RPC servers.  When an RPC server
     begins operation, it tells portmap the port number being monitored and
     the program numbers being serviced by the RPC server.  A client host
     sending RPC packets to a particular program number gets the appropriate
     port number from portmap.
