WHAT IS REMOTE ACCESS?
The ability to get accesses to a computer or a network from
a remote distance
Used for telecommuters accessing to the corporations’
network, home users accessing Internet
METHODS OF REMOTE ACCESS
Dial – up connection over regular telephone line is the
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
WHAT IS GOOD?
Easy to install
Good for IT professional deal with people who have
difficult conversations on the computer environments
Manage your network servers easier
3 REMOTE ASSESS/CONTROL
• What is GoToMyPC
• Good and bad points of GoToMyPC
• What is VNC
• Server overview
• Network setup
• Old window version
• Windows XP
• Features of TightVNC
WHAT IS GOTOMYPC?
GoToMyPC is one of the remote access options
It is simply the fastest, easiest and the most secure way to access
a PC remotely
It features on-the-fly access from any location connected to the
Internet and the highest level of security.
It allows us to work on our office PCs from home
Increase flexibility and productivity by allowance in access of
files, programs and networks in an easy, secure access from
GOOD POINTS OF
Better security features
Built in management features
Go to the GoToMyPC site at www.gotomypc.com
Register, download and install GoToMyPC on
your Internet-connected host computer.
Remotely access your computer from any PC with
a Web browser at GoToMyPC with no additional
software to install
Begin working on your host computer as if you
were sitting in front of it. You can immediately
access your email, applications, documents and
Its traffic is encrypted with Advanced
Encryption Standard (AES) 128-bit encryption
using a secure challenge-response password
It removes the motivation for users to install
no secure modems on their PCs, since they use
their existing internet connection.
BAD POINTS OF
Needs broadband connections for best performance
Relatively more expensive than other remote access
THINGS WE CAN DO WITH
Transfer files back and forth.
Print from your remote PC to a local printer.
Access your PC from another PC, Mac, Linux or Unix.
Invite others to share your PC to collaborate or do
demos... and much more.
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
Consisted two components
• Free download
• Download at http://realvnc.com/
• Small program
• Easy to install & operate
SERVER PROPERTIES VIEW
• Setup Password
• Disable Remote keyboard &
• Disable Local keyboard &
Default Display Port Number
would be 0 & Auto
Enter remote IP
address or Host name
• Successfully connect
• Fail to connect
One workstation to
• 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?
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
It can be very helpful in distance learning and
remote customer support
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.
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
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.
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
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
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
And, has sufficient security and management features
