"This article presents an overview of SSH, the Secure SHell. This is the first part of a two part series, introducing SSH and the major implementations - except OpenSSH. Part2 will focus on the new OpenSSH."
"SSH is so useful, easy to use and so much more secure than the archaic telnet/rlogin/rsh, that no UNIX system should be installed without it. Ideally all OS vendors would follow the example of OpenBSD & Suse, and bundle SSH with the OS."
