'ssh' (Secure SHell) is an ecrypted (safe) means of connecting to remote computers. It can be used provide complete control of any machine, given proper access, from anywhere in the world. It is safe than 'telnet' which is open and inherently insecure.
The ssh client is automatically installed with all YDL package sets and allows you to "ssh out". But to get to your local machine from remote machine, you need to install the ssh server in order to "ssh in".
Insert the YDL Install CD and as root:
mount /dev/cdrom /mnt/cdrom [ENTER]
rpm -Uvh openssh-server* [ENTER]
