Methods of remote access
Methods of Remote Access

  • Dial – up connection over regular telephone line is the common method

  • Dedicated line between a computer and a remote LAN, is more expensive and less flexible, but is faster

  • ISDN combines dial-up connection with a faster data transfer

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

  • Support for two passwords (full-control and read-only).

  • Advanced Properties dialog in WinVNC

  • Flexible configuration options

  • Automatic SSH tunneling on Unix

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


  • For us, we prefer VNC because…..

  • It is a small program that we can download

  • Easily

  • Freely

  • And, has sufficient security and management features
