WHAT IS REMOTE ACCESS?

T

he ability to get accesses to a computer or a

network from a remote distance

U

sed for telecommuters accessing to the

corporations’ network, home users accessing

Internet

METHODS OF REMOTE ACCESS

D

ial – up connection over regular telephone line is the

common method

D

edicated line between a computer and a remote LAN, is

more expensive and less flexible, but is faster

I

SDN combines dial-up connection with a faster data transfer

WHAT IS GOOD?

E

asy to install

G

ood for IT professional deal with people who have

difficult conversations on the computer environments

M

anage your network servers easier

SECURITY

Its traffic is encrypted with Advanced Encryption Standard (AES) 128-bit encryption using a secure challenge-response password authentication protocol.

It removes the motivation for users to install no secure modems on their PCs, since they use their existing internet connection.

Screen Blanking

Keyboard Locking

BAD POINTS OF GOTOMYPC

N

eeds broadband connections for best performance

R

elatively more expensive than other remote access options

THINGS WE CAN DO WITH GOTOMYPC

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?

V

NC stands for Virtual Network Computing

A

remote control software thru TCP/IP protocol

C

ommonly used on Windows or Unix system.

D

evelopment by AT&T Laboratories Cambridge

GETTING STARTED WITH VNC

Consisted two components

• Server• Viewer

Advantage

• Free download• Download at http://realvnc.com/

• Small program• Easy to install & operate

SERVER PROPERTIES VIEWS

etup Properties• Setup Password• Disable Remote

keyboard & Pointer• Disable Local keyboard

& PointerD

efault Display Port Number would be 0 & Auto

Server Standby View

VIEWER (REMOTE CONTROLLER)

Enter remote IP address or Host name

Password Authentication

• Successfully connect• Fail to connect

One workstation to many servers

NETWORK SETUP

D

irect Connection• No additional setup• Connect to IP address directly

N

etwork Under Router (Linksys, Dlink…)• Setup port number 5500 or 5900 on Forwarding Service.

F

ind 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 environments.

It can be very helpful in distance learning and remote customer support

OLD WINDOWS VERSION

M

ost of today's internet uses IPv4, which is now

nearly twenty years old

b

oth client (VNCviewer) and Server (WinVNC)

were changed to support Internet Protocol

Version 6 (IPv6) as transport protocol.

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

L

ocal cursor handling

E

fficient compression algorithms

C

onfigurable compression levels

O

ptional JPEG compression

E

nhanced Web browser access

S

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

A

dvanced Properties dialog in WinVNC

Flexible configuration options

A

utomatic SSH tunneling on Unix

COMPATIBILITY AND INTEROPERABILITY

T

ightVNC is fully compatible with

the standard RFB protocol used in

VNC.

CONCLUSION

W

hich is better??

T

he answer depends on our usage

G

otoMyPC has a better feature in security and management

V

NC – a small, easy to use and free program

T

ightVNC has a better feature in web-browsing / internet

RECOMMENDATION

F

or us, we prefer VNC because…..

I

t is a small program that we can download

E

asily

F

reely

A

nd, has sufficient security and management features
