FreeOS.com: Replacing Telnet; OpenSSH, a secure alternative

"The Internet is built with communication in mind. You will routinely move around the Web from one site to the other or telnet to another machine to check your mail or to administer that machine. The trouble with most of these protocols is that they are not encrypted. Over a telnet connection, your passwords are sent as plain-text, which can be read by anyone. Using sophisticated programs called packet sniffers, even a amateur hacker can spy on your connection and grab your data."

"Secure Shell (SSH) was built to address these faults and provide a more secure environment to work in. SSH encrypts all your traffic including your passwords when you connect to another machine over the net. SSH also replaces telnet, ftp, rsh, rlogin and rexec."
