PORTMAP Meaning and
Definition
-
Portmap is a computer software tool or service that acts as a communication intermediary between network clients and servers. It operates within the Transmission Control Protocol/Internet Protocol (TCP/IP) suite, specifically functioning as a remote procedure call (RPC) service. Portmap helps to establish connections and allocate ports for various network services, enabling clients to access servers by identifying the appropriate port numbers.
Portmap primarily handles the mapping of RPC program numbers to the corresponding port numbers on servers. This mapping process allows clients to specify the service they wish to use, while Portmap locates the appropriate port associated with that service on the server. It simplifies the process by providing a centralized method for both clients and servers to communicate and exchange data.
In practical terms, Portmap operates as a daemon or service running on a server, listening for client requests and responding with the required information. It functions as a backbone infrastructure service, facilitating numerous network operations such as file sharing, network printing, and remote administration.
Portmap is an essential component in networked systems, enabling reliable communication between clients and servers. However, due to security vulnerabilities, potential attacks, and the availability of alternative protocols, Portmap usage has declined in recent years, with many systems transitioning to more secure alternatives like RPCBIND or employing secure RPC configurations.
