The Remote Execution (REXEC) server is a Transmission Control Protocol/Internet Protocol (TCP/IP) application that allows a client user to submit system commands to a remote server system. The Remote Execution Protocol (REXEC) allows processing of these commands or programs on any host in the network. The local host then receives the results of the command processing.
The user's client program sends the user identifier, password, and command to run to the server. The server validates the user, runs the requested command, and returns the results of the command to the client.
