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 protects the user from illicit network snooping ("packet sniffing"), whereby un-encrypted passwords and text can be read by unscrupulous persons. SSH is most useful for logging into a UNIX computer from a Windows or Mac computer or from another UNIX computer, where the traditional 'telnet' and 'rlogin' programs would not provide password and session encryption; the CSUA administrative personnel tend to use SSH exclusively in preference to telnet or rlogin, except in cases where SSH is not available.
