How To Install rsh-server on CentOS 8
Introduction
In this tutorial we learn how to install rsh-server on CentOS 8.
What is rsh-server
The rsh-server package contains a set of programs which allow users to run commands on remote machines, login to other machines and copy files between machines (rsh, rlogin and rcp). All three of these commands use rhosts style authentication. This package contains the servers needed for all of these services. It also contains a server for rexec, an alternate method of executing remote commands. All of these servers are run by systemd and configured using systemd units and PAM. The rsh-server package should be installed to enable remote access from other machines
