3 MAKING A VIEWER CONNECTION
The KLE provides a win32 viewer for Windows clients and a Java viewer for cross-
platform on any major operating systems.
3.1 Install Win32 Viewer on the Client
Computer
Go to the Download page to download the Win32 viewer, Kripview_install.exe. Install
the viewer program on the client computer that will connect to KLE. After installation,
a desktop icon will be created on your client desktop.
3.2 Install Java Viewer on the client
computer
Before you can use the java viewer, KViewer.jar, on any OS platform, you should
first install the Java Runtime Environment, JRE 1.5.0 or higher, which is
downloadable from http://www.java.com.
To download Java Viewer, just go to the Download page of the Web Management
interface.

KLE User Guide R1.2
After all, to run the small java program, you don’t have to actually save the Kviewer.jar to your local hard
disk, since it is small (only 70 KB), you can choose to open it directly wile download is completed.
On some client platforms such as Linux, after you have installed the JRE on your client platform, you
have to set the path information in order for the client system to know where the Java compiler program is.
3.3 Import certificates to KLE viewer on the
client computer
If you will be using only the non-PKI authenticated viewer connections to KLE (such as Level 1 – No
encryption and No Authentication
, and Level 2 – 128-bit SSL encryption and only server authentication by
client
), you are not obliged to use or import any certificates. If so you can skip this section and proceed to the
next.
To make full PKI authenticated viewer connection with KLE, you need to import client
certificates to the Win32 viewer and Java Viewer on the client computer.
The KLE is already preinstalled with a default set of certificates. You can use the
default client certificates provided on CD ROM. However, it also allows you to use
your own set of certificates.
Note that if you intend to use your own set of certificates instead of the default set of certificates, you
should not only import the client certificates to the win32 viewer/java viewer on remote client computer, but
you should also import the root certificate, server certificate and the server private key to the KLE. To
import certificates to the KLE, please go to the Security page of the KLE Web Management to upload your
own set of certificates. For details, please refer to
Section 4.16, Security – Certificate Installation, Viewer
Encryption and Password Policies
.
Generally, the naming requirements of these certificates are as follows:
[Certificates and private key for KLE to authenticate viewer user logins]
root.crt - KLE root certificate, mandatory file name
server.crt - KLE server certificate, mandatory file name
- -
25
serverkey.pem-KLE server private key, mandatory file name

KLE User Guide R1.2
[Certificates for remote login users with viewer connections]
client_name1.p12 - client certificate, client name could vary
client_name2.p12 - client certificate, client name could vary
. . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Specifically, we should import client certificate(s) in .p12 format, to the win32 viewer
and Java Viewer on your client computer, using each of their own certificate import
utilities.
First, you have to have your certificates ready, either on a removable media or you
can copy them to your local disk on the client computer.
Note that if you copy certificates to your local hard disk, you might need to delete them from your local
hard disk after finishing importation, so that others won’t have access to your certificate files. Although the
personal client certificate (that is, the
client_name1.p12 ) is password-protected, more caution is never to
blame!
Note that the win32 viewer and the java viewer require separate certificate
importation utility to get the job done.
Import client certificate to Win32 Viewer
Run the importation utility by accessing Start/Programs/PROSUM /KLE
Viewer/Import Certificates. Click Root Certificate to import root certificate and then
click Client Certificate to import client certificate.
Import the certificates for the Java-based KLE Viewer
Now you have imported certificates to the viewers on the client computer
and are now ready for making a viewer connection of any security level
setting …. - -

3.5 Establish the viewer connection
Using Win32 KLE Viewer for Connection
First, run the viewer program, enter the access IP and port number for KLE.
Default IP address: 192.168.1.200
Login dialog box (Win32 Viewer)
At the password or private path phrase prompt, just enter the user name and
password as required:
Default user & specific password:
User: superuser
Password: superu
Or, if you are using the Global Password policy setting …
Default global password: 123456
Or, if you are using the Level 3 security setting that requires installation of
certificates for PKI authentication (For details, please refer to section 3.3, Import
certificates to KLE Viewer on the client Computer, and Section 4.16, Security –
Certificates Installation, Viewer Encryption and Password Policies.)
Default private path phrase: clientpwd
After you have entered either the global password, user name and password, or
private path phrase as its security and password policy require, a viewer connection
will be established successfully.

Some Tips about Viewer Connection
If you want to specify the type of your viewer connection rather than using the default one, you can click
the
Options button and optimize your connection parameters. Please refer to previous section for details.
Note that you can simply type in the access IP of KLE server without specifying its
port number only when the port number is default to 5900
IP_address [only if port number is default to 5900]
192.168.1.200
Of course, you can always type
IP_address:port_number
192.168.1.200:5900
However, if the port setting on KLE is already changed to other port number, you
have to specify its specific port number following the IP address. For example, if you
want to connect to port 5910 on the KLE server, type, for example:
192.168.1.8:5910
To configure the port base number, please refer to Section, 4.12., LAN TCP/IP – Port and IP Settings .

Connection Performance Tuning
However, if you are using a dial-up modem line and experiencing slow keyboard
mouse movement and response, you might check whether you are using the default
LAN encoding scheme or even the RAW scheme, which requires much more packet
quantity in transmitting a video frame; or there is a network bottleneck somewhere
in between KLE and your client desktop. For more details, please refer to Section
3.13, Common Video Display Problem Troubleshooting.
3.6 Mouse Cursors Synchronization
Normally, you will see both the local cursor and the remote cursor on the view area.
You can specify the shape of the local cursor as seen within the Viewer Window
either as a dot, an arrow or none (not showing any local cursor within the viewer
area). Also if these two cursors become out of sync, all you need to do is to hit
default the mouse synchronization hotkey (right) Ctrl – (right) Ctrl – Home to
synchronize the two cursors.
Mouse cursors out of sync Mouse cursors in Sync
Local/remote cursor resynchronization hotkey- RCtrl-RCtrl-Home
Note that, while operating your mouse, it is not necessary to wait till the remote cursor has actually
caught up with the local one before you can click on the target in the view area. Actually, you can click the
target just using the local cursor well before your remote cursor catches up the target!
3.7 Save the Connection Options
After you have optimized you connection options, you might want to save the
connection options. Next time when you log in with the KLE viewer to KLE server,
the viewer on that specific client computer will use the stored connection parameters
as well as the password (but not the private path phrase, which is not saved since it
is used by secured/PKI-authenticated connection) for connection with KLE.
To save connection options, click the KLE icon on the Viewer title bar to call forth
the Viewer Quick Menu and select Save the connection options.

to operate on as the win32 viewer interface.
3.13 Common Video Display Problem
Troubleshooting
KLE video server supports most major display modes up to 1280 x 1024. However,
some display problems will occurs, when either there is abnormal or unusual display
output from your server or the display resolution is over the biggest support of 1280
x 1024, or the display vertical frequency is beyond the support range in that pixel
dimension.
To yield best video results on the viewer screen display on remote login client, you
should also refer to Section 2.2, Prepare your Computers for Connections to KLE,
and Section, 2.3, More Tips for Server Desktop Configuration for more details about
how to prepare your servers/computers before getting them connected to your KLE.
The followings are some common video display problems and their troubleshooting….
Q. There seems to be many artifacts or residuals not getting refreshed on the viewer
screen. Is there any way to improve the video display quality on viewer screen?
A: The causes of these artifacts or residuals could be:
(1) The video filter currently active on KLE is either set at Medium Quality or Low Quality
Level. These two video filter levels are for faster response than the High Quality Level
