SSH is the most popular method for connecting to remote computers to run Unix commands. It is secure alternative to rsh, rlogin, and telnet. The leading implementation is OpenSSH. The source code for OpenSSH is free, meaning that anyone can check how safe it is. Most BSD, Linux, and Unix vendors include OpenSSH. In short, telnet is obsolete, except in applications that require no security. This page ought to discuss: * Who uses SSH? * How was SSH developed? * What are the SSH implementations? (OpenSSH is not the only one.) * Can I get an SSH account somewhere?
