PURPOSE

Maps program numbers to port numbers to make service calls.

SYNTAX


portmap ---|


DESCRIPTION

The portmap program maps RPC program number to the port numbers on RPC servers
in order for NFS clients to make RPC service calls.  When an RPC server starts,
it contacts the portmap program to register the RPC programs it is prepared to
serve and the port on which it is listening for calls.  When NFS clients call
an RPC procedure for a given program number, the clients contact the portmap
program to determine the port number to which they should send the packets.

The portmap program is started from /etc/rc.tcpip.
