Name
portmap - DARPA internet port to RPC program number mapper
Syntax
/usr/etc/portmap
Description
The command is a server that converts RPC program numbers into DARPA protocol port numbers. When an RPC server is started, it will tell
what TCP or UDP port number it is listening on, and what RPC program numbers it is prepared to serve.
It is important to understand that must first be invoked before attempting to run any RPC service. It must be running in order to use any
RPC-based applications, including the NFS mount daemon, When a client wishes to make an RPC call to a given program number, the RPC program
will first contact on the server machine to determine the port number where the RPC packets should be sent.
If crashes, all servers must be restarted.
