1- Go to the Linux source CDs and search for the 2 packages rsh* and rsh-server and install the 2 packages rsh and rsh-server with these commands as root user

# rpm -Uvh rsh*
# rpm -Uvh rsh-server*

2- Enable remote shell and rlogin by doing the following as root user and ensure that there's no error
