Setting Up Secure Shell (SSH)
Instead of Telnet, you can use Secure Shell, which creates a more secure session than the Telnet
application that uses an unencrypted data stream. SSH uses encrypted keys to send data so that
your username and password are not sent in the clear. Table 1.9 lists the commands.
