Remote Shell Protocol (rsh) is a protocol that allows a user to execute commands on a remote system without having to log in to the system. For example, rsh can be used to remotely examine the status of a number of access servers without connecting to each communication server, executing the command, and then disconnecting from the communication server. rsh originated as part of the BSD Unix operating system as part of the rlogin package on 4.2BSD in 1983. rsh has since been ported to other operating systems. rsh is mostly replaced by a more secured protocol called Secure Shell protocol(SSH) in today's environment.
