Secure Shell (SSH) is an Internet communication protocol used to exchange data using a secure channel between two computers. It is used mainly on Linux and Unix.
SSH was designed by Tatu Ylönen in 1995 to replace the insecure protocols rlogin, Telnet and rsh, which were used to access shell accounts.
