SSH (Secure Shell) is a program to log into another computer over a network to execute commands in a
remote machine and to move files from one machine to another. It provides strong authentication and secure
communications over insecure channels. It is intended as a replacement for rlogin, rsh, and rcp.
SSH is a command line interface. Access via SSH is encrypted.
For access via SSH, you need SSH Client, which most Linux systems already include. For MS Windows, the
program PuTTY is very common as a SSH client.
