The remote shell (rsh) is a command-line computer program that can execute shell commands as another user, and on another computer across a computer network.
The remote system to which rsh connects runs the rsh daemon (rshd). The daemon typically uses the well-known Transmission Control Protocol (TCP) port number 513.
