"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."
"Let's take a look at OpenSSH, an excellent and more importantly open source implementation of SSH. It is very well supported by the OpenBSD team and includes rock-solid SSH2 support. Versions are available for nearly all the Unices including Linux, which is what we are using here."
