SSH is a protocol that *replaces* telnet and rsh. The OpenSSH and other
server versions of SSH come with clients automatically, usually called
"ssh". Read the manual page to learn more about it.

SSH encrypts the connection, can authenticate the users with a personal
key to avoid having to type passwords every time, can directly do file
copies with the "scp" command, and can authenticate the host you connect
to and from to prevent people from trying to fake out your machines with
their own replacement machines, and can support "rsync" use over a
safely encrypted channel as well.

Hit the web pages at www.openssh.org, they'll explain more.
