RealVNC
 Virtual
Network
Computing (VNC) is a graphical desktop sharing system which uses the
RFB protocol to remotely control another computer. It transmits the
keyboard and mouse events from one computer to another, relaying any
changes to the screen that may occur, over a network. VNC operates
either as a server, generating a display delivered remotely, or as a
client actually drawing the received display to your screen.
VNC is platform-independent — a VNC viewer on any
operating system can connect to a VNC server on any other
operating system. Multiple clients may connect to a single VNC
server
at the same time.
Popular use of this technology includes system administration where
administrators can take control of a machine to diagnose and fix
problems remotely. Physical access to the console is not necessary with
this application. VNC is in widespread use throughout industry,
academia and privately, and
the free edition is included in all major Linux distributions.
Besides the Free edition, VNC is also available in personal and
enterprise editions, both released under proprietary commercial
licenses.
RealVNC was founded and staffed by the original AT&T team who
created VNC. VNC has spawned a number of derivative products including
UltraVNC and TightVNC.
Features include:
- Uses TCP/IP protocol to remotely control computers across
the internet
- Simple challenge-response protocol (Enterprise and
Personal Edition include support for strong encryption and
authentication - 2048-bit RSA Server Authentication, 128-bit AES
Session Encryption and Tamper-Proofing)
- Can be tunnelled over an SSH or VPN connection
- Legacy VNC 3 Compatibility
