<p>Today, secure shell basks in the adoration that <tt class="COMMAND">telnet</tt> once
enjoyed. <tt class="COMMAND">ssh</tt>(1) allows one to make a connection to a remote
machine and execute programs as if one were physically present; however, <tt
class="COMMAND">ssh</tt> encrypts all the data travelling between the two computers so
even if others intercept the conversation, they are unable to understand it. A typical
secure shell connection follows.</p>
