Two versions of Secure Shell protocol are available: SSH version 1 (SSH1) and SSH Version 2 (SSH2). SSH2 is a complete rewrite of the protocol with improved security, performance, and portability than the legacy version SSH1. SSH is intended as a replacement for telnet, rlogin, rsh, and rcp. SSH2 adds a replacement for FTP (SFTP). For more information on the protocols, see the Internet Engineering Task Force (IETF) web site at http://www.ietf.org/.
