2. Introduction
The KVM over IP technology (DKVM-IP8) combines digital remote KVM access via IP
networks with comprehensive and integrated system management. The DKVM-IP8 defines
a new class of remote KVM access devices that can save your money, time, space, and
equipment.
The DKVM-IP8 provides convenient, remote KVM access and control via LAN or Internet. It
captures, digitizes, and compresses video signal and transmits it with keyboard and mouse
signals to and from a remote computer. DKVM-IP8 provides a non-intrusive solution for
remote access and control. Remote access and control software runs on its embedded
processors only but not on mission-critical servers, so that there is no interference with
server operation or impact on network performance.
The DKVM-IP8 supports console of USB style keyboard, mouse, and HDDB15 video
interfaces. The DKVM-IP8 will automatically detect the current video mode of the console,
however manual fine-tuning is recommended to receive the best video quality.

2.4 When the server is up and running
The DKVM-IP8 gives you a full control over the remote server. The Management Console
allows you to access the remote server’s graphics, keyboard and mouse and to send
special commands to the server. You can also perform periodic maintenance of the server.
Using the Console Redirection Service, you are able to do the following:
I. Reboot the system
II. Watch the boot process.
III. Boot the system from a separate partition to load the diagnostic environment.
IV. Run special diagnostic programs.
2.5 When the server is dead
Obviously, fixing hardware defects is not possible through a remote management device.
Nevertheless DKVM-IP8 gives the administrator valuable information about the type of a
hardware failure. Serious hardware failures can be categorized into five different categories
with different chances to happen:
I. Hard disk failure 50%
II. Power cable detached, power supply failure 28%
III. CPU, Controller, main board failure 10%
IV. CPU fan failure 8%
V. RAM failure 4%

4. IP module Configuration
4.1 Initial Configuration
If DHCP mode is enabled (IP auto configuration = DHCP), the DKVM-IP8 will try to
contact a DHCP server in the subnet to which it is physically connected. If a DHCP
server is found, it may provide a valid IP address, gateway address and net mask.
Before you connect the device to your local subnet, be sure to complete the
corresponding configuration of your DHCP server. It is recommended to configure a
fixed IP assignment to the MAC address of the DKVM-IP8. You can find the MAC
address labeled on the bottom side of the metal housing.
If DHCP mode is disabled (IP auto configuration = None), the factory default IP
settings are as below:
IP address 192.168.0.70
Subnet mask 255.255.255.0
Default Gateway None
Table 4-1 Initial Network Configurations
DKVM-IP8 Setup Tool
If this initial configuration does not meet your local requirements, use the setup tool to
change the configurations to your needs. The setup tool PSetup can be found on the
CD ROM delivered with this package. You can follow the procedures described below.
■ DHCP
If you have installed the DKVM-IP8 on a network that enables DHCP, you can use
the PSetup to find out the DKVM-IP8’s I P.
(1) Plug Ethernet cable to DKVM-IP8. DKVM-IP8 will get an IP via DHCP.
(2) Using PSetup (run PSetup.exe) to look for DKVM-IP8.
a. Select MAC address which label on bottom of DKVM-IP8
b. Click Query Device
Notes:
BOOTP, a static configuration protocol, uses a table that maps IP
addresses to physical addresses.

With this option, you can specify whether the DKVM-IP8 should get its network
settings from a DHCP or BOOTP server. For DHCP, enter “dhcp”, and for BOOTP
enter “bootp”. If you do not specify any of these, the IP auto-configuration is
disabled and subsequently you will be asked for the following network settings.
IP address
The IP address the DKVM-IP8. This option is only available if IP auto-configuration
is disabled.
Net mask
The net mask of the connected IP subnet. This option is only available if IP
auto-configuration is disabled.
Gateway address
The IP address of the default router for the connected IP subnet. If you do not have
a default router, enter 0.0.0.0. This option is only available if IP auto-configuration is
disabled.
4.2 Keyboard, Mouse, and Video configuration
Between the DKVM-IP8 and the host, there are two interfaces available for
transmitting keyboard and mouse data: USB and PS/2. The correct operation of the
remote mouse depends on several settings which will be discussed in the following
subsections.
4.2.1 DKVM-IP8 keyboard settings
The DKVM-IP8 settings for the host's keyboard type have to be corrected in order to
make the remote keyboard work properly. Check the settings in the DKVM-IP8 Web
front-end. See section 6.5.2 for details.
4.2.2 Remote Mouse Settings
A common seen problem with KVM devices is the synchronization between the local
and remote mouse cursors. The DKVM-IP8 addresses this situation with an intelligent
synchronization algorithm. There are two mouse modes available on the DKVM-IP8:
Auto mouse speed
The automatic mouse speed mode tries to detect the speed and acceleration
settings of the host system automatically. See the section below for a more
detailed explanation.
Fixed mouse speed
This mode just translates the mouse movements from the Remote Console in a
way that one pixel move will result in n-pixel moves on the remote system. This
33 / 104
Page 34
DKVM-IP8 User Manual
parameter n is adjustable with the scaling. Please note that this works only when
mouse acceleration is turned off on the remote system.
4.2.3 Automatic mouse speed and mouse synchronization
The automatic mouse speed mode performs the speed detection during mouse
synchronization. Whenever the local and remote mouse cursors move synchronously
or not, there are two ways for re-synchronizing local and remote mouse cursors:
Fast Sync
The fast synchronization is used to correct a temporary, but fixed skew. Choose
the option using the Remote Console options menu or press the mouse
synchronization hotkey sequence in case you defined one.
Intelligent Sync
If the fast sync does not work or the mouse settings have been changed on the
host system, use the intelligent resynchronization. This method takes more time
than the fast one and can be accessed with the appropriate item in the Remote
Console option menu. The intelligent synchronization requires a correctly
adjusted picture. Use the auto adjustment function to setup the picture, and make
sure that there are no window at the top left corner of the remote desktop that are
able to change the mouse cursor shape from the normal state. The Sync mouse
button on top of the Remote Console can behave differently, depending on the
current state of mouse synchronization. Usually pressing this button leads to a
fast sync, except in situations where the KVM port or the video mode changed
recently.
Note: At first start, if the local mouse pointer is not synchronized with
the remote mouse pointer, press the Auto Adjust Button once.
4.2.4 Host system mouse settings
The host's operating system knows various settings from the mouse driver.
Warning
The following limitations do not apply in case of USB and Mouse Type
“Windows >= 2000, MacOSX”.
While the DKVM-IP8 works with accelerated mice and is able to synchronize the local
with the remote mouse pointer, there are the following limitations, which may prevent
this synchronization from working properly:
Special Mouse Driver
There are mouse drivers that influence the synchronization process and lead to
desynchronized mouse pointers. If this happens, make sure you do not use a
special vendor-specific mouse driver on your host system.
34 / 104
Page 35
DKVM-IP8 User Manual
Windows XP Mouse Settings
Windows XP knows a setting named “improve mouse acceleration”, which has to
be deactivated.
Active Desktop
If the Active Desktop feature of Microsoft Windows is enabled do not use a plain
background. Instead, use some kind of wallpaper. As an alternative, you could
also disable the Active Desktop completely.
Navigate your mouse pointer into the upper left corner of the applet screen and
move it slightly forth and back. Thus the mouse will be resynchronized. If
re-synchronizing fails, disable the mouse acceleration and repeat the procedure.
4.2.5 Single and Double Mouse Mode
The information above applies to the Double Mouse Mode, where remote and local
mouse pointers are visible and need to be synchronized. The DKVM-IP8 also
features another mode, the Single Mouse Mode, where only the remote mouse
pointer is visible. Activate this mode in the open Remote Console and click into the
window area. The local mouse pointer will be hidden and the remote one can be
controlled directly. To leave this mode, it is necessary to define a mouse hotkey in the
Remote Console Settings Panel. Press this key to free the captured local mouse
pointer.
4.2.6 Recommended Mouse Settings
For the different operating systems we can give the following advice:
MS Windows 2000/2003 (Professional and Server) and XP (all versions)
In general, we recommend the usage of a mouse via USB. Choose USB without
Mouse Sync. For a PS/2 mouse choose Auto Mouse Speed. For XP disable the option
“enhance pointer precision” in the Control Panel.
SUN Solaris
Adjust the mouse settings either via xset m 1 or use the CDE Control Panel to set the
mouse to “1:1, no acceleration”. As an alternative you may also use the Single Mouse
Mode.
MAC OS X
We recommend using the Single Mouse Mode.
4.2.7 Video Modes
The DKVM-IP8 recognizes a limited number of common video modes. When running
X11 on the host system, please do not use any custom mode lines with special video
modes. If you do, the DKVM-IP8 may not be able to detect them. We recommend
using any of the standard VESA video modes, instead.

5. Usage
5.1 Prerequisites
The DKVM-IP8 features an embedded operating system and applications offering a variety
of standardized interfaces. This chapter will describe both these interfaces, and the way to
use them in a more detailed manner. The interfaces are accessed using the TCP/IP
protocol family, thus they can be accessed using the LAN port of the device.
The following interfaces are supported:
HTTP/HTTPS
Full access is provided by the embedded web server. The DKVM-IP8 environment can
be entirely managed using a standard web browser. You can access the DKVM-IP8
using the insecure HTTP protocol, or using the encrypted HTTPS protocol. Whenever
possible, use HTTPS.
Telnet
A standard Telnet client can be used to access an arbitrary device connected to the
DKVM-IP8's serial port via a terminal mode.
The primary interface of the DKVM-IP8 is the HTTP interface. This is covered
extensively in this chapter. Other interfaces are addressed in subtopics.
In order to use the Remote Console window of your managed host system, the browser
has to come with a Java Runtime Environment version 1.4.2 or above. If the browser has
no Java support (such as on a small handheld device), you are still able to maintain your
DKVM-IP8 using the administration forms displayed by the browser itself.
For an insecure connection to the DKVM-IP8, we can recommend the following browsers:
• Microsoft Internet Explorer version 6.0 or higher on Windows 2000 and Windows XP
• Netscape Navigator 7.0 or Mozilla 1.6 on Windows 2000, Windows XP, Unix, Linux and
UNIX-like Operating Systems
In order to access the remote host system using a securely encrypted connection, you
need a browser that supports the HTTPS protocol. Strong security is only assured by using
a key length of 256 Bit. Some of the old browsers do not have a strong 256 Bit encryption
algorithm.
Using the Internet Explorer, open the menu entry “?” and “Info” to read about the key
length that is currently activated. The dialog box contains a link that leads you to
information on how to upgrade your browser to a state of the art encryption scheme.
Figure 5-1 shows the dialog box presented by the Internet Explorer 6.0.
36 / 104
Page 37
DKVM-IP8 User Manual
Figure 5-1. The Internet Explorer displaying the encryption key length
Newer web browsers generally support strong encryption on default.
5.2 Login into the DKVM-IP8 and logout
5.2.1 Login into the DKVM-IP8
Launch your web browser. Direct it to the address of your DKVM-IP8, which you
configured during the installation process. The address used might be an IP address or
a domain name, in the case where you have given your DKVM-IP8 a symbolic name in
the DNS. For instance, type the following in the URL field of your browser when
establishing an unsecured connection:
http://<IP address of DKVM-IP8>
When using a secure connection, type in:
https://<IP address of DKVM-IP8>
This will lead you to the DKVM-IP8 login page as shown in Figure 5-2.
Figure 5-2. Login screen
The DKVM-IP8 has a built-in super user that has all permissions to administrate your

Warning
The user “super” is not allowed to login via the serial interface of the
DKVM-IP8.
Warning
Please make sure to change the super user password immediately after you
have installed and accessed your DKVM-IP8 for the first time. Unchanging of
the password for the super user is a severe security risk and might result in
unauthorized access to the DKVM-IP8 and to the host system including all
possible consequences!
Warning
Your web browser has to accept cookies, or else login is not possible.
Navigation
Having logged into the DKVM-IP8 successfully, the main page of the DKVM-IP8
appears (see Figure 5-3). This page consists of three parts; each of them contains
specific information. The buttons on the upper side allow you to navigate within the
front end (see Table 5-2 for details). Within the right frame, task-specific information is
displayed that depends on the section you have chosen before.

Return to the main page of the DKVM-IP8 .
Open the DKVM-IP8 remote console.
Exit from the DKVM-IP8 front end.
Warning
If there is no activity for 30 minutes, the DKVM-IP8 will log you out,
Table 5-2. Buttons from the front end
automatically. A click on one of the links will bring you back to the login screen.
5.2.2 Logout from the DKVM-IP8
This link logs out the current user and presents a new login screen. Please note that an
automatic logout will be performed in case there is no activity for 30 minutes.
5.3 The Remote Console
The Remote Console is the redirected screen, keyboard and mouse of the remote host
system that DKVM-IP8 controls.
39 / 104
Page 40
DKVM-IP8 User Manual
Figure 5-4. Remote Console
The Remote Console window is a Java Applet that tries to establish its own TCP
connection to the DKVM-IP8. The protocol that is run over this connection is neither
HTTP or HTTPS, but RFB (Remote Frame Buffer Protocol). As default, RFB tries to
establish a connection to TCP port number 443. Your local network environment has to
allow this connection to be made, i.e. your firewall and, in case you have a private
internal network, your NAT (Network Address Translation) settings have to be
configured accordingly.
In case the DKVM-IP8 is connected to your local network environment and your
connection to the Internet is available using a proxy server only without NAT being
configured, the Remote Console is very unlikely to be able to establish the desired
connection. This is because today's web proxies are not capable of relaying the RFB
protocol.
In case of problems, please consult your network administrator in order to provide an
appropriate networking environment.
5.4 Main Window
Starting the Remote Console opens an additional window. It displays the screen
content of your host system. The Remote Console will behave exactly in the same way
as if you were sitting locally in front of the screen of your remote system. That means
keyboard and mouse can be used in the usual way. However, be aware of the fact that
the remote system will react to keyboard and mouse actions with a slight delay. The
delay depends on the bandwidth of the link to which you use to connect to the
DKVM-IP8.
40 / 104
Page 41
DKVM-IP8 User Manual
With respect to the keyboard, the very exact remote representation might lead to some
confusion as your local keyboard changes its keyboard layout according to the remote
host system. If you use a German administration system, and your host system uses a
US English keyboard layout, for instance, special keys on the German keyboard will
not work as expected. Instead, the keys will result in their US English counterpart. You
can circumvent such problems by adjusting the keyboard of your remote system to the
same mapping as your local one.
The Remote Console window always tries to show the remote screen with its optimal
size. That means it will adapt its size to the size of the remote screen initially and after
the screen resolution of the remote screen has been changed. However, you can
always resize the Remote Console window in your local window system as usual.
Warning
In difference to the remote host system, the Remote Console window on your
local window system is just one window among others. In order to make
keyboard and mouse work, your Remote Console window must have the local
input focus.
5.4.1 Remote Console Control Bar
The upper part of the Remote Console window contains a control bar. Using its
elements you can see the state of the Remote Console and adjust the local Remote
Console settings. A description for each control follows.
Figure 5-5. Remote Console Control Bar
Ctrl+Alt+Delete
Special button key to send the “Control Alt Delete” key combination to the remote
system (see also section 6.4.1 for defining new button keys).
Auto Adjust button
If the video display is of bad quality or distorted in some way, press this button and
wait a few seconds while the DKVM-IP8 tries to detect the video mode of VGA port
to the controlled host and adjust itself for the best possible video quality.
Sync mouse
Activates the mouse synchronization process. Choose this option in order to
synchronize the local with the remote mouse cursor. This is especially necessary
when using accelerated mouse settings on the host system. In general, there is no
need to change mouse settings on the host.

Single/Double mouse mode
Switches between the Single Mouse Mode (where only the remote mouse pointer
is visible) and the Double Mouse Mode (where remote and local mouse pointers
are visible and need to be synchronized). Single mouse mode is only available if
using SUN JVM 1.4.2 or higher.
Options
To open the Options menu, click on the button “Options”.
Figure 5-6. Remote Console Options Menu
A short description of the options follows.
• Monitor Only
Toggles the Monitor only filter on or off. If the filter is switched on no remote
console interaction is possible, and monitoring is possible.
• Exclusive Access
If a user has the appropriate permission, he or she can force the Remote
Consoles of all other users to close. No one can open the Remote Console at the
same time again until this user disables the exclusive access, or logs off.
A change in the access mode is also visible in the status line (see Figure 5-7).

DKVM-IP8 User Manual
• Scaling
Allow you to scale down the Remote Console. You can still use both mouse and
keyboard, however the scaling algorithm will not preserve all display details.
When you designate 25%, 50%, or100% scaling, the size of Remote Console
window is calculated according to the remote host video setting with scaling

• Mouse Handling
The submenu for mouse handling offers two options for synchronizing the local
and the remote mouse cursors.
Fast Sync --
The fast synchronization is used to correct a temporary, but fixed skew.
Intelligent Sync --
Use this option if the fast sync does not work or the mouse settings have
been changed on the host system.
Warning
This method takes more time than the fast one and requires a correctly
adjusted picture. Use the auto adjustment function to setup the picture.
• Local Cursor
Offers a list of different cursor shapes to choose from for the local mouse pointer.
The selected shape will be saved for the current user and activated the next time
this user opens the Remote Console. The number of available shapes depends
on the Java Virtual Machine; a version of 1.4.2 or above offers the full list.

• Video Settings
Opens a panel for changing the DKVM-IP8 video settings. DKVM-IP8 features
two different dialogs, which for adjusting the video settings.
Video Settings through the HTML-Frontend
To enable local video port, select this option. This option decides if the local
video output of DKVM-IP8 is active and passing through the incoming signal
from the host system.
The option Noise Filter defines how DKVM-IP8 reacts to small changes in the
video input signal. Turning on the noise filter can help reduce video flickering
that is often caused by distortions, as well as lowering unnecessary
bandwidth consumption. A large filter setting needs less network traffic and
leads to a faster video display, but small changes in some display regions
may not be recognized immediately. A small filter displays all changes
instantly but may lead to a constant amount of network traffic even if display
content is not really changing (depending on the quality of the video input
signal). All in all the default setting should be suitable for most situations.

Used to change the language mapping of your browser machine running the
Remote Console Applet. Normally, the applet determines the correct value
automatically. However, depending on your particular JVM and your browser
settings this is not always possible. A typical example is a German localized
system that uses an US-English keyboard mapping. In this case you have to
change the Local Keyboard setting to the right language, manually.

• Encoding
These options are used to adjust the encoding level in terms of compression and
color depth. They are only available unless "Transmission Encoding" is
determined automatically (see the Section called Transmission Encoding in
Chapter 6).
Compression Level: you may select a value between 1 and 9 for the desired
compression level with level 1 enabling the fastest compression and level 9 the
best compression. The most suitable compression level should always be seen
as a compromise between the network bandwidth that is available, on your
video picture to be transferred, and on the number of changes between two
single video pictures. We recommend to use a higher compression level if the
network bandwidth is low. The higher the compression level the more time is
needed to pack and unpack the video data on either side of the connection. The
compression quality depends on the video picture itself, e.g. the number of the
colors or the diversity of pixels. The lower the compression quality, the more
data have to be sent and the longer it may take to transfer the whole video
picture.
47 / 104
Page 48
DKVM-IP8 User Manual
If level 0 is chosen the video compression is disabled, completely.
The option "Video Optimized" has its advantages if transferring high-quality
motion pictures. In this case the video compression is disabled, completely and
all video data is transferred via network as full-quality video snippets. Therefore,
a high amount of bandwidth is required to ensure the quality of
the video picture.
Figure 5-14. Encoding Compression
Color Depth: set the desired color depth. You may select between 8 or 16 bit
for Video Optimized/compression level 0, or between 1 and 8 bit for
compression level 1 to 9. The higher the color depth, the more video information
has to be captured and to be transferred.
Figure 5-14. Encoding Color depth

Page 49
DKVM-IP8 User Manual
Note: If displaying motion pictures on a connection with low speed you may
achieve an improvement regarding the video transfer rate by lowering the color
depth and disabling the option "Video Optimized". As a general result, the data
rate is reduced (less bits per color). Furthermore, the IPKVM module will not have
to do any video compression. In total, this will lead to less transfer time of the
motion picture.
5.4.2 Remote Console Status Line
Status line
Shows both console and the connection state. The size of the remote screen is
displayed. Figure 5-15 was taken from a Remote Console with a resolution of
800x600 pixels. The value in brackets describes the connection to the Remote
Console. “Norm” means a standard connection without encryption, “SSL” means a
secure connection.

Furthermore, both the incoming (“In:”) and the outgoing (“Out:”) network traffic are
visible (in kb/s). If compressed encoding is enabled, a value in brackets displays
the compressed transfer rate.

DKVM-IP8 User Manual
The DKVM-IP8 firmware features a Telnet server that enables a user to connect via a
standard Telnet client. In case the Telnet program is using a VT 100, VT 102 or VT 220
terminal or an according emulation, it is even possible to perform a console redirection
as long as the DKVM-IP8 host machine is using a text mode screen resolution.
Connecting to the DKVM-IP8 is done as usual and as required by the Telnet client, for
instance in a UNIX shell:
telnet 192.168.0.70
Replace the IP address by the one that is actually assigned to the DKVM-IP8. This will
prompt for username and password in order to log into the device. The credentials that
need to be entered for authentication are identical to those of the web interface. That
means, the user management of the Telnet interface is entirely controlled with the
according functions of the web interface.
Once you have successfully logged into the DKVM-IP8 a command line will be
presented and you can enter according management commands.
In general, the Telnet interface supports two operation modes: the command line mode
and the terminal mode. The command line mode is used to control or display some
parameters. In terminal mode the pass-through access to serial port 1 is activated (if
the serial settings were configured accordingly). All inputs are redirected to the device
on serial port 1 and its answers are displayed on the Telnet interface.
The following list shows the according command mode command syntax and their
usage.

Creating an Image
Floppy Images
UNIX and UNIX-like OS
To create an image file, make use of “dd”. This is one of the original UNIX utilities and
is included in every UNIX-like OS (UNIX, Sun Solaris, and Linux).
To create a floppy image file, copy the contents of a floppy to a file. You can use the
following command:
dd [ if=/dev/fd0 ] [ of=/tmp/floppy.image ]
dd reads the entire disc from the device /dev/fd0, and saves the output in the
specified output file /tmp/floppy.image. Adjust both parameters exactly to your needs
(input device etc.)
MS Windows
You can use the tool “Raw Write for Windows”. It is included on the CD ROM shipped
with DKVM-IP8.
