Secure Shell (SSH), sometimes known as Secure Socket
Shell, is a Unix-based command interface and protocol for securely getting
access to a remote computer. It is widely used by network administrators
to control Web and other kinds of servers remotely. SSH is actually a
suite of three utilities - slogin, ssh, and scp - that are secure versions
of the earlier UNIX utilities, rlogin, rsh, and rcp. SSH commands are
encrypted and secure in several ways. Both ends of the client/server connection
are authenticated using a digital certificate, and passwords are protected
by being encrypted.
