what is vnc
What is VNC?
  • VNC stands for Virtual Network Computing
  • A remote control software thru TCP/IP protocol
  • Commonly used on Windows or Unix system.
  • Development by AT&T Laboratories Cambridge
getting started with vnc
Getting Started with VNC
  • Consisted two components
    • Server
    • Viewer
  • Advantage
    • Free download
      • Download at
    • Small program
    • Easy to install & operate
server properties view
Server Properties View
  • Setup Properties
    • Setup Password
    • Disable Remote keyboard & Pointer
    • Disable Local keyboard & Pointer
  • Default Display Port Number would be 0 & Auto
viewer remote controller
Viewer (Remote Controller)
  • Enter remote IP address or Host name
  • Password Authentication
    • Successfully connect
    • Fail to connect
  • One workstation to many servers
network setup
Network Setup
  • Direct Connection
    • No additional setup
    • Connect to IP address directly
  • Network Under Router (Linksys, Dlink…)
    • Setup port number 5500 or 5900 on Forwarding Service.
  • Find out what is IP address
    • Ipconfig, Email heading, netstat….
what is tightvnc
What is TightVNC?
  • It includes a lot of new features, improvements, optimizations and bugfixes over the original of VNC version .
  • It is still free, cross-platform and compatible with the standard VNC.
  • It can be used to perform remote control and administration tasks in Windows and mixed network environments.
  • It can be very helpful in distance learning and remote customer support
old windows version
Old Windows Version
  • Most of today's internet uses IPv4, which is now nearly twenty years old
  • both client (VNCviewer) and Server (WinVNC) were changed to support Internet Protocol Version 6 (IPv6) as transport protocol.
windows xp
Windows XP
  • IPv6 is the "next generation" protocol designed by the IETF to replace the current version Internet Protocol, IP Version 4 ("IPv4").
  • In the actual IPv6 release only one protocol is supported at the same time, it means that TightVNC only works in IPv4 or IPv6 at time.
  • If XP has the IPv6 support installed, the server run under IPv6
  • Due to the Microsoft IPv6 stack implementation, it is not possible to make IPv4 connections when the server is running in IPv6, a future work will support it.
tightvnc features
TightVNC Features
  • Local cursor handling
  • Efficient compression algorithms
  • Configurable compression levels
  • Optional JPEG compression
  • Enhanced Web browser access

compatibility and interoperability
Compatibility and Interoperability
  • TightVNC is fully compatible with the standard RFB protocol used in VNC.
  • Which is better??
  • The answer depends on our usage
  • GotoMyPC has a better feature in security and management
  • VNC – a small, easy to use and free program
  • TightVNC has a better feature in web-browsing / internet
