1 Conguration

1-1 Initial Conguration

If DHCP mode is enabled (IP auto conguration = DHCP), the IP module 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 conguration of your DHCP server. It is recommended to congure a xed IP assignment to
the MAC address of the IP module. You can nd the MAC address labeled on the bottom side of the metal

housing.

If DHCP mode is disabled (IP auto conguration = None), the factory default IP settings are as below:

IP Address 192.168.1.22

Subnet Mask

Default Gateway

IP Module Setup Tool

If this initial conguration does not meet your local requirements, use the setup tool to change the
congurations 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.

255.255.255.0

None

1. DHCP

If you have installed the IP module on a network that enables DHCP, you can use the PSetup to nd out the

IP module’s IP.

1. Plug Ethernet cable to IP module. IP MODULE will get an IP via DHCP.

2. Using PSetup (run PSetup.exe) to look for IP MODULE.

a. Select MAC address which label on bottom of IP module

b. Click Query Device

Notes:

■ BOOTP, a static conguration protocol, uses a table that maps IP addresses to physical addresses.

■ DHCP, an extension to BOOTP that dynamically assigns conguration information. DHCP is

backward compatible with BOOTP.

1

2. Setup Fixed IP

c. Setup “IP auto configuration” as “ None” ; setup IP address and Subnet mask

d. Enter Super user login and password for Authentication (default : super/pass)

e. Click Setup Device. If super login was authenticated, it’ll show “Successfully configured device”.

Otherwise it’ll show “Permission Denied”.

Authentication

To adjust the authentication settings, enter your login as a super user, and change your password.

Super user login

Enter the login name of the super user. The initial value is “super”. All characters
are in lower case.

Super user password

Enter the current password for the super user. This initial value is “pass”. All
characters are in lower case.

New super user password

Enter the new password for the super user.

New password (conrm)

Re-type the new password for the super user for conrmation.

To close the window and accept the changes, press the “OK” button; otherwise

press the “Cancel” button.

1-1.1 Setup Fixed IP

For using serial terminal, the IP module has a serial line interface (host side). This

connector is compliant with the RS-232 serial line standard. The serial line has to be

congured with the parameters given in the table below.

When conguring with a serial terminal, e.g., Hyper Terminal, reset the IP module and
immediately press the “ESC” key. You will see some device information, and a “=>”

2

prompt. Enter “cong”, press “Enter” key and wait for a few seconds for the
conguration questions to appear.

Parameter Value

Bits/second 115200

Data bits 8

Parity No

Stop bits 1

Flow Control None

As you proceed, the following questions will appear on the screen. To accept the
default values shown in square brackets below, press “Enter” key.

IP auto conguration (none/dhcp/bootp):
IP [192.168.1.22]:
Net mask [255.255.255.0]:
Gateway (0.0.0.0 for none) [0.0.0.0]:

IP Auto-Conguration

With this option, you can specify whether the IP module 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-conguration is disabled and subsequently you will be asked for the following network

settings.

IP Address

The IP address the IP module. This option is only available if IP auto-conguration is disabled.

Net Mask

The net mask of the connected IP subnet. This option is only available if IP auto-conguration 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-conguration is disabled.

1-2 Keyboard, Mouse and Video Conguration

Between the IP module 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.

1-2.1 IP Module Keyboard Settings

The IP module 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 IP module Web front-end. See section 3.5.2 for details.

1-2.2 Remote Mouse Settings

A common seen problem with KVM devices is the synchronization between the local and remote mouse
cursors. The IP module addresses this situation with an intelligent synchronization algorithm. There are two

mouse modes available on the IP module:

Auto Mouse Speed

The automatic mouse speed mode tries to detect the speed and acceleration settings of the host system

3

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 parameter n is adjustable with the scaling. Please
note that this works only when mouse acceleration is turned off on the remote system.

1-2.3 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 xed skew. Choose the option using the
Remote Console options menu or press the mouse synchronization hotkey sequence in case you
dened 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 windows 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 rst start, if the local mouse pointer is not synchronized with the remote mouse pointer, press

the Auto Adjust Button once.

1-2.4 Host System Mouse Settings

The host’s operating system knows various settings from the mouse driver.

Warning

While the IP module 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:

While the IP module 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 inuence the synchronization process and lead to desynchronized mouse
pointers. If this happens, make sure you do not use a special vendor-specic mouse driver on your host

system.

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.

4

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.

1-2.5 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 IP module 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 dene a mouse hotkey in the Remote Console Settings Panel. Press

this key to free the captured local mouse pointer.

1-2.6 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.

1-2.7 Video Modes

The IP module 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 IP module may
not be able to detect them. We recommend using any of the standard VESA video modes, instead.

5

2 Usage

2-1 Prerequisites

The IP module 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 IP module environment can be entirely managed

using a standard web browser. You can access the IP module 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 IP module’s serial
port via a terminal mode. The primary interface of the IP module 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 IP module using the administration forms displayed by the

browser itself.

Note: We recommend installing a Sun JVM 1.5.0.4.

For an insecure connection to the IP module, 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 128 Bit. Some of the old
browsers do not have a strong 128 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. The image below shows the dialog box presented by the Internet Explorer

6.0.

Newer web browsers generally support strong encryption on default.

6

2-2 Login into the IP Module and Logout

2-2.1 Login into the IP Module

Launch your web browser. Direct it to the address of your IP module, which you congured during the
installation process. The address used might be an IP address or a domain name, in the case where you
have given your IP module a symbolic name in the DNS. For instance, type the following in the URL eld of
your browser when establishing an unsecured connection:

http://<IP address of IP module>

When using a secure connection, type in:

https://<IP address of IP module>

This will lead you to the IP module login page as shown below.

The IP module has a built-in super user that has all permissions to administrate your IP module:

Warning

■ The user “super” is not allowed to login via the serial interface of the IP module

■ Please make sure to change the super user password immediately after you

have installed and accessed your IP module for the rst time. Unchanging of

the password for the super user is a severe security risk and might result in
unauthorized access to the IP module and to the host system including all possible

consequences!

■ Your web browser has to accept cookies, or else login is not possible.

Navigation

Having logged into the IP module successfully, the main page of the IP module appears. This page consists
of three parts; each of them contains specic information. The buttons on the upper side allow you to
navigate within the front end. Within the right frame, task-specic information is displayed that depends on

the section you have chosen before.

7

Return to the main page of the IP module.

Open the IP module remote console.

Exit from the IP module front end.

Warning

If there is no activity for 30 minutes, the IP module will log you out, automatically. A

click on one of the links will bring you back to the login screen.

2-2.2 Logout from the IP Module

This link logs out the current user and presents a new login screen. Please note that an automatic logout
will be performed if there is no activity for 30 minutes.

2-3 The Remote Console

The Remote Console is the redirected screen, keyboard and mouse of the remote host system that IP module

controls.

The Remote Console window is a Java Applet that tries to establish its own TCP connection to the IP

module. 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 rewall and, in case you have a private internal
network, your NAT (Network Address Translation) settings have to be congured accordingly.

In case the IP module is connected to your local network environment and your connection to the Internet is

available using a proxy server only without NAT being congured, 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.

8

2-4 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 IP module.

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 systemis just one window among others. In order to make keyboard and

mouse work, your Remote Console window must have the local input focus.

2-4.1 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.

Ctrl+Alt+Delete

Special button key to send the “Control Alt Delete” key combination to the remote system (see also

section 3.4.1 for dening 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 IP module 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”.

9

A short description of the options follows.

■ Monitor Only

Toggles the Monitor only lter on or off. If the lter 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.

■ 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 xed 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.

10

■ Video Settings

Opens a panel for changing the IP module video settings. IP module 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 IP

module is active and passing through the incoming signal from the host system.

The option Noise Filter denes how IP module reacts to small changes in the video input signal.
Turning on the noise lter can help reduce video ickering that is often caused by distortions, as
well as lowering unnecessary bandwidth consumption. A large lter setting needs less network
trafc and leads to a faster video display, but small changes in some display regions may not be
recognized immediately. A small lter displays all changes instantly but may lead to a constant
amount of network trafc 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.

Video Settings through the remote console:

Brightness

Controls the brightness of the picture

Contrast

Controls the contrast of the picture

Clock

Denes the horizontal frequency for a video line and depends on the video mode. Different
video card types may require different values here. The default settings in conjuction with the
auto adjustment procedure should be adequate for all common congurations. If the picture
quality is still bad after auto adjustment you may try to change this setting together with the
sampling phase to achieve a better quality.

Phase

Denes the phase for video sampling, used to control the display quality together with the

setting for sampling clock.

Horizontal Position

Use the left and right buttons to move the picture in horizontal direction while this option is
selected.

11

Vertical Position

Use the left and right buttons to move the picture in vertical direction while this option is
selected.

Reset this Mode

Reset mode specic settings (Clock , Phase and Position) to the factory-made defaults.

Reset all Modes

Reset all settings to the factory-made defaults.

Save changes

Save changes permanently

Undo Changes

Restore last settings

■ Refresh Video

Click to run this menu item for retrieving the whole video again from the controlled host and displayed

on Remote Console. In normal situation, only changed parts of video will be packed and sent from IP
module, for saving network bandwidth. This function is mainly used for troubleshooting purpose where
some old video fragments are displayed as not updated in time for some reason; for example, noise
lter for VGA is setting too large.

■ Soft Keyboard

Opens up the Menu for the Soft-Keyboard.

■ Show

Pops up the Soft-Keyboard. The Soft-Keyboard is necessary in case your host
system runs a completely different language and country mapping than your
administration machine.

■ Mapping

Used for choosing the specic language and country mapping of the

Soft-Keyboard.

12

■ Local Keyboard

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.

■ Hotkeys

Opens a list of hotkeys dened before. Choose one entry, the command will be sent to the host

system.

A conrmation dialog can be added that will be displayed before sending the selected command to
the remote host. Select “OK” to execute the command on the remote host.

■ 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 3).

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.

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.

13

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.

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 OPMA module will not have to do any video compression. In total, this will lead to less transfer

time of the motion picture.

2-4.2 Remote Console Status Line

Status line

Shows both console and the connection state. The size of the remote screen is displayed. The image below
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 trafc are visible (in kb/s). If
compressed encoding is enabled, a value in brackets displays the compressed transfer rate.

For more information about Monitor Only and Exclusive Access settings, see related

sections

3-1 Remote Control

3-1.1 KVM Console

To open the KVM console, either click on the menu entry on the left, or on the console
picture on the right. To refresh the picture, click on the button “Refresh”.

3-1.2 Telnet Console

The IP module rmware 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 IP module host machine is using a text mode
screen resolution.

15

Connecting to the IP module is done as usual and as required by the Telnet client, for instance in a UNIX
shell:

telnet 192.168.1.22

Replace the IP address by the one that is actually assigned to the IP module. 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 IP module 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 congured 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.

help

Displays the list of possible commands

cls

Clears the screen

quit

Exits the current session and disconnects from the client

version

Displays the release information

terminal

Starts the terminal passthrough mode for serial port 1. The key sequence

esc exit

switches back to the command mode.

below. Click “Apply” to submit your changes.

3-2.2 Users and Groups

The IP module comes with 1 pre-congured user account that has xed permissions. The account “super”
has all possible rights to congure the device and to use all functions IP module offers.

Upon delivery, the account “super” has the password “pass”. Make sure to change password immediately

after you have installed and on initial access of your IP module.

Existing users

Select an existing user for modication. Once a user has been selected, click the lookup button to see

the user information.

New User Name

The new user name for the selected account.

Password

The password for the login name. It must be at least three characters long.

Conrm password

Conrmation of the password above.

Email address

This is optional.

Mobile number

This information may be optionally provided.

Role

Each user can be a member of a group (named a “role” ) - either an administrator, or an regular user.

Choose the desired role from the selection box.

To create an user press the button “Create”. The button “Modify” changes the displayed user settings. To
delete an user press the button “Delete”.

Note:The IP MODULE is equipped with an host-independent processor and memory unit which both have a

17

limitation in terms of the processing instructions and memory space. To guarantee an acceptable response

time we recommend not to exceed the number of 15 users connected to the IP MODULE at the same time.
The memory space that is available onto the IP MODULE mainly depends on the conguration and the
usage of the IP MODULE (log le entries etc.). That’s why we recommend not to store more than 150 user
proles.

The following settings are user specic. That means, the super user can customize these settings for every

users separately. Changing the settings for one user does not affect the settings for the other users.

User select box

This selection box displays the user ID for which the values are shown and for
which the changes will take effect. You may change the settings of other users if

you have the required privileges.

Remote Console Type

Species, which Remote Console Viewer to use.

Default Java-VM

Uses the default Java Virtual Machine of your Browser. This may be the Microsoft JVM for the Internet

Explorer, or the Sun JVM if it is congured this way. Use of the Sun JVM may also be forced (see

18

below).

Sun Microsystems Java Browser Plugin

Instructs the web browser of your administration system to use the JVM of Sun Microsystems. The

JVM in the browser is used to run the code for the Remote Console window, which is actually a Java
Applet. If you check this box for the rst time on your administration system and the appropriate Java
plug-in is not already installed on your system, it will be downloaded and installed automatically.
However, in order to make the installation possible, you still need to answer the according dialogs with

“yes” . The download volume is around 11 Mbytes. The advantage of downloading Sun’s JVM lays in
providing a stable and identical Java Virtual Machine across different platforms. The Remote Console
software is optimized for this JVM versions and offers wider range of functionality when run in SUN’s
JVM. Please make sure that you are installing Sun JVM 1.4.2 or above to your client system.

Miscellaneous Remote Console Settings

■ Start in Monitor Mode

Sets the initial value for the monitor mode. By default the monitor mode is off. In case you switch it

on, the Remote Console window will be started in a read only mode.

■ Start in Exclusive Access Mode

Enables the exclusive access mode immediately at Remote Console startup. This forces 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.

Mouse Hotkey

Allows to specify a hotkey combination which starts either the mouse synchronization process if

pressed in the Remote Console, or is used to leave the single mouse mode.

Remote Console Button Keys

Button Keys allow simulating keystrokes on the remote system that cannot be generated locally.

The reason for this might be a missing key or the fact, that the local operating system of the Remote

Console is unconditionally catching this keystroke already. Typical examples are “Control+Alt+Delete”

on Windows and DOS, what is always caught, or “Control+Backspace” on Unix or Unix-like OS for
terminating the X-Server. The syntax to dene a new Button Key is as follows:

[conrm] <keycode>[+|-[*]<keycode>]*

“conrm” requests conrmation by a dialog box before the key strokes will be sent to the remote host.

“keycode” is the key to be sent. Multiple key codes can be concatenated with a plus, or a minus sign.
The plus sign builds key combinations, all keys will be pressed until a minus sign or the end of the
combination is encountered. In this case all pressed keys should be released in reversed sequence. The
minus sign builds single, separate key presses and releases. The star inserts a pause with duration of

100 milliseconds.

19

3-3.2 Keyboard / Mouse

Host Interface

Enables a certain interface the mouse is connected to. You can choose between “Auto” for automatic

detection, “USB” for an USB mouse, and “PS/2” for a PS/2 mouse.

Warning

To use the USB and/or PS/2 interface you need a correct cabling between the
managed host and the managing device. If the managed host has no USB keyboard

support in the BIOS and you have connected the USB cable only then you will have no

remote keyboard access during the boot process of the host. If USB and PS/2 are both

connected and you selected “Auto” as host interface, then the card will select “USB” if

available or otherwise falls back to “PS/2”.

To get USB remote keyboard access during the boot process of the host, the following conditions must
be fullled:

■ The host BIOS must have USB keyboard support

■ The USB cable must be connected or must be selected in the Host interface option

PS/2 Keyboard Model

Enables a certain keyboard layout. You can choose between “Generic 101-Key PC” for a standard

keyboard layout, “Generic 104-Key PC” for a standard keyboard layout extendend by three additional
windows keys, “Generic 106-Key PC” for a japanese keyboard, and “Apple Macintosh” for the Apple

Macintosh.

Keyboard timeout

Recommanded as “enable” for keyboard timeout when host is UNIX or UNIX-like OS.

USB Mouse Type

Enables USB mouse type. Choose between “Windows >= 2000 , MacOSX” for MS Windows 2000 or
Windows XP, Mac OSX or “Other Operating Systems” for MS Windows NT, Unix or Unix-like OS, or
OS X. In “Windows >= 2000 , MacOSX” mode the remote mouse is always synchronized with the local

mouse.

20

Mouse Speed

■ Auto mouse speed

Use this option if the mouse settings on host use an additional acceleration
setting. The IP module tries to detect the acceleration and speed of the mouse
during the mouse sync process.

■ Fixed mouse speed

Use a direct translation of mouse movements between the local and the remote
pointer.

You may also set a xed scaling which determines the pixel-amount of the

remote mouse pointer movement when the local mouse pointer is moved by one
pixel. This option is used to manually control the remote mouse speed and only
works when the mouse settings on the host are linear. This means mouse

acceleration of OS should be disabled, and the intelligent mouse synchronization

of IP module is not functioning under this setting.

To set the options, click on the button “Apply”.

3-3.3 Video

Miscellaneous Video Settings

■ Noise lter

This option denes how the IP module reacts to small changes in the video input signal. Turning on
the noise lter can help reduce video ickering that is often caused by distortions, as well as lowering
unnecessary bandwidth consumption. A large lter setting needs less network trafc and leads to a
faster video display, but small changes in some display regions may not be recognized immediately. A
small lter displays all changes instantly but may lead to a constant amount of network trafc even if the
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.

■ Force Composite Sync (Required for Sun Computers)

21

When connecting the device directly to legacy Sun computer (with composite sync as the video output,
it may be possible that IP MODULE don’t recognize the composite sync automatically. To support signal
transmission from a Sun machine, enable this option. If not enabled the picture of the remote console will
not be visible. To set the options, click on the button “Apply”

3-4 Device Settings

3-4.1 Network

The Network Settings panel as shown below allows changing network related parameters. Each parameter

will be explained below. Once applied the new network settings will immediately come into effect.

Warning

The initial IP conguration is usually done directly at the host system using the

special procedure.

Changing the network settings of the IP module might result in losing
connection to it. In case you change the settings remotely make sure that all
the values are correct and you still have an option to access the IP module.

IP Auto Conguration

With this option you can control if the IP module should fetch its network settings

from a DHCP or BOOTP server. For DHCP, select “dhcp” , and for BOOTP select
“bootp” accordingly. If you choose “none” then IP auto conguration is disabled.

IP Address

IP address in the usual dot notation.

Subnet Mask

The net mask of the local network.

Gateway IP Address

In case the IP module should be accessible from networks other than the local one,

this IP address must be set to the local network router’s IP address.

22

Primary DNS Server IP Address

IP address of the primary Domain Name Server in dot notation. This option may be

left empty, however the IP module will not be able to perform name resolution.

Secondary DNS Server IP Address

IP address of the secondary Domain Name Server in dot notation. It will be used in
case the Primary DNS Server cannot be contacted.

Remote Console And HTTPS port

Port number at which the IP module’s Remote Console server and HTTPS server
are listening. If left empty the default value will be used.

HTTP Port

Port number at which the IP module’s HTTP server is listening. If left empty the
default value will be used.

Telnet Port

Port number at which the IP module’s Telnet server is listening. If left empty the
default value will be used.

Bandwidth Limitation

The maximum network trafc generated through the IP module ethernet device.

Value in Kbit/s.

Enable Telnet Access

Set this option to allow accessing the IP module using the Telnet
Gateway see the section 6.1.2.

Disable Setup Protocol

Enable this option to exclude the IP module from the setup protocol. Setup protocol

is a proprietary layer-2 MAC-based protocol to allow some conguration software
to detect IP MODULE devices in the network, even without IP address, and then
cong network related settings to IP module.

LAN Interface Settings

The “Autodetect” will set the ethernet speed to the fastest possible value supported

by both endpoints of the link. For example, if you use a 10M/half duplex HUB, this

speed will be auto-selected. If this option does not work with some network device

(HUB, switches, and routers), you can set the Ethernet interface speed of IP

module manually to the values as supported by the network device.

3-4.2 Dynamic DNS

23

A freely available Dynamic DNS service (www.dyndns.org) can be used in the following scenario:

The IP module is reachable via the IP address of the DSL router, which is dynamically assigned by the
provider. Since the administrator does not know the IP address assigned by the provider, the IP module

connects to a special dynamic DNS server in regular intervals and registers its IP address there. The
administrator may contact this server as well and pick up the same IP address belonging to his card.

The administrator has to register an IP module that is supposed to take part in the service with the Dynamic
DNS Server and assign a certain hostname to it. He will get a nickname and a password in return to the
registration process. This account information together with the hostname is needed in order to determine
the IP address of the registered IP module.

You have to perform the following steps in order to enable Dynamic DNS:

■ Make sure that the LAN interface of the IP module is properly congured.

■ Enter the Dynamic DNS Settings conguration dialog.

■ Enable Dynamic DNS and change the settings according to your needs (see below).

Enable Dynamic DNS

This enables the Dynamic DNS service. This requires a congured DNS server IP address.

Dynamic DNS server

This is the server name where IP module registers itself in regular intervals. Currently, this is a xed

setting since only dyndns.org is supported for now.

DNS System

Choose Dynamic for free DNS service. Custom for your own domain.

Hostname

This is the hostname of the IP module that is provided by the Dynamic DNS Server. (use the whole name

including the domain, e.g. testserver.dyndns.org , not just the actual hostname).

Username

You have registered this username during your manual registration with the Dynamic DNS Server.
Spaces are not allowed in the Nickname.

Password

You have used this password during your manual registration with the Dynamic DNS Server.

24

Check time

The IP module registers itself for initiating the IP address of IP module stored in the Dynamic DNS server
at this time.

Check interval

This is the interval for reporting again to the Dynamic DNS server for updating the IP address associated
with the Domain Name of the IP module.

Warning

The IP module has its own independent real time clock. Make sure the time setting of

the IP module is correct. (see the Section called Date And Time)

3-4.3 Security

Force HTTPS

f this option is enabled access to the web front-end is only possible using an HTTPS connection. The IP
module will not listen on the HTTP port for incoming connections.

In case you want to create your own SSL certicate that is used to identify the IP module refer to the
Section called Certicate.

KVM Encryption

This option controls the encryption of the RFB protocol. RFB is used by the Remote Console to transmit
both the screen data to the administrator machine and keyboard and mouse data back to the host. If set

to “Off” no encryption will be used.

25

3-4.4 Certicate

The IP module uses the Secure Socket Layer (SSL) protocol for any encrypted network trafc between itself

and a connected client. During the connection establishment the IP module has to expose its identity to a

client using a cryptographic certicate. The default certicate comes with IP MODULE device upon delivery
is for testing purpose only. System administrator should not rely on this default certicate as the secured

global access mechanism through Internet.

However, it is possible to generate and install a new base64 X.509 certicate that is unique for a particular
IP module. In order to do that, the IP module is able to generate a new cryptographic key and the
associated Certicate Signing Request (CSR) that needs to be certied by a certication authority (CA). A
certication authority veries that you are the person who you claim you are, and signs and issues a SSL
certicate to you.

The following steps are necessary to create and install a SSL certicate for the IP
module:

■ Create a SSL Certicate Signing Request using the panel shown below. You need to ll out a number
of elds that are explained below. Once this is done, click on the button “Create” which will initiate the
Certicate Signing Request generation. The CSR can be downloaded to your administration machine

with the “Download CSR” button.

■ Send the saved CSR string to a CA for certication. You will get the new certicate from the CA after a

more or less complicated traditional authentication process (depending on the CA).

■ Upload the certicate to the IP module using the “Upload” button as shown below.

26

This is the interval for reporting again to the Dynamic DNS server for updating the IP address associated
with the Domain Name of the IP module.

Warning

The IP module has its own independent real time clock. Make sure the time

setting of the IP module is correct. (see the Section called Date And Time)

Common Name

This is the network name of the IP module once it is installed in the user’s network (usually the fully

qualied domain name). It is identical to the name that is used to access the IP module with a web
browser (without the “http://” prex). In case the name given here and the actual network name differ, the

browser will pop up a security warning when the IP module is accessed using HTTPS.

Organizational Unit

This eld is used for specifying to which department within an organization the IP module belongs.

Organization

The name of the organization to which the IP module belongs.

Locality/City

The city where the organization is located.

State/Province

The state or province where the organization is located.

Country (ISO code)

The country where the organization is located. This is the two-letter ISO code, e.g. DE for Germany, or
US for the USA. (Note: the country code has to be entered in CAPITAL LETTERS.)

Challenge Password

Some certication authorities require a challenge password to authorize later changes on the certicate
(e.g. revocation of the certicate). The minimal length of this password is 4 characters.

Conrm Challenge Password

Conrmation of the Challenge Password

Email

The email address of a contact person that is responsible for the IP module and its security.

27

Key length

This is the length of the generated key in bits. 1024 Bits are supposed to be sufcient for most cases.

Longer keys may result in slower response time of the IP module during connection establishment.

3-4.5 Serial Port

The IP module Serial Settings allows you to specify what device is connected to the serial port and how to
use it.

Conguration or console login

Do not use the serial port for any special function, use it only for the initial conguration.

Modem

The IP module offers remote access using a telephone line in addition to the standard access over the
built-in Ethernet adapter. The modem needs to be connected to the serial interface of the IP module.

Logically, connecting to the IP module using a telephone line means nothing else than building up a

dedicated point-to-point connection from your console computer

to the IP module. In other words, the IP module acts as an Internet Service
Provider (ISP) to which you can dial in. The connection is established using the
Point-to-Point Protocol (PPP). Before you connect to the IP module, make sure to
congure your console computer accordingly. For instance, on Windows based
operating systems you can congure a dial-up network connection, which defaults

to the right settings like PPP.

The Modem Settings panel allows you to congure the remote access to the IP

module using a modem. The meaning of each parameter will be described below.
The modem settings are part of the serial settings panel.

Serial line speed

The speed the IP module is communicating with the modem. Most of all modems available today
will support the default value of 115200 bps. In case you are using an old modem and discovering
problems try to lower this speed.

28

Modem Init String

The initialization string used by the IP module to initialize the modem. The default value will work
with all modern standard modems directly connected to a telephone line. In case you have a special

modem or the modem is connected to a local telephone switch that requires a special dial sequence
in order to establish a connection to the public telephone network, you can change this setting by

giving a new string. Refer to the modem’s manual about the AT command syntax.

Modem server IP address

This IP address will be assigned to the IP module itself during the PPP handshake. Since it is a

point-to-point IP connection virtually every IP address is possible but you must make sure, it is not

interfering with the IP settings of the IP module and your console computer. The default value will
work in most cases.

Modem client IP address

This IP address will be assigned to your console computer during the PPP handshake. Since it is a

point-to-point IP connection virtually every IP address is possible but you must make sure, it is not

interfering with the IP settings of the IP module and your console computer. The default value will
work in most cases.

Passthrough access to serial port via Telnet

Using this option, it is possible to connect an arbitrary device to the serial port and access it (assuming it
provides terminal support) via Telnet. Select the appropriate options for the serial port and use the Telnet
Console, or a standard Telnet client to connect to the IP module.

3-4.6 Date and Time

This link refers to a page, where the internal real-time clock of the IP module can be set up (see Figure
3-32). You have the possibility to adjust the clock manually, or to use a NTP timeserver. Without a
timeserver, your time setting will not be persistent, so you have to adjust it again, after IP module loses
power for more than a few minutes. To avoid this, you can use a NTP timeserver, which sets up the internal
clock automatically to the current UTC time. Because NTP server time is always UTC, there is a setting that

allows you to set up a static offset to get your local time.

Warning

There is currently no way to adjust the daylight saving time automatically. So you
have to set up the UTC offset twice a year properly to the local rules of
your country.

29

3-4.7 Event Log

Important events like a login failure or a rmware update are logged to a selection of logging destinations.
Each of those events belongs to an event group, which can be activated separately.

The common way to log events is to use the internal log list of the IP module. To show the log list, click on

“Event Log” on the “Maintenance” page. In the Event Log Settings you can choose how many log entries

are shown on each page. Furthermore, you can clear the log le here.

List logging enabled

The common way to log events is to use the internal log list of the IP module . To show the log list, click

on “Event Log” on the “Maintenance” page.

Since the IP module’s system memory is used to save all the information, the maximum number of

possible log list entries is restricted to 1.000 events. Every entry that exceeds this limit overrides the

oldest one, automatically.

Warning

If the reset button on the HTML frontend is used to restart the IP module, all

logging information is saved permanently and is available after the IP module

has been started. If the IP module loses power or a hard reset is performed, all
logging data will be lost. To avoid this, use one of the following log methods.

NFS Logging Enabled

Dene a NFS server, where a directory or a static link have to be exported, to write all logging data to a
le that is located there. To write logging data from more than one IP module devices to only one NFS
share, you have to dene a le name that is unique for each device. When you change the NFS settings
and press the button “Apply” , the NFS share will be mounted immediately. That means, the NFS share
and the NFS server must be lled with valid sources or you will get an error message.

30

SMTP Logging enabled

With this option, the IP module is able to send Emails to an address given by the Email address text eld
in the Event Log Settings. These mails contain the same description strings as the internal log le and
the mail subject is lled with the event group of the occurred log event. In order to use this log destination
you have to specify a SMTP server, that has to be reachable from the IP module device and that needs
no authentication at all (<serverip>:<port>).

SNMP Logging enabled

If this is activated, the IP module sends a SNMP trap to a specied destination IP address, every time a
log event occurs. If the receiver requires a community string, you can set it in the appropriate text eld.
Most of the event traps only contain one descriptive string with all information about the log event. Only
authentication and host power events have an own trap class that consists of several elds with detailed
information about the occurred event. To receive this SNMP traps, any SNMP trap listener may be used.

Here is a example of all gerenated event and its event group.

Warning

In contrast to the internal log le on the IP module, the size of the NFS log le
is not limited. Every log event will be appended to the end of the le so it grows

continuously and you may have to delete it or move it away from time to time.

3-5 Maintenance

3-5.1 Device Information

Device Summary

This section contains a summary with various information about this IP module and it’s current rmware

and allows you to reset the card.

The Data le for support allows you to download the IP module data le with specic support information.
This is an XML le with certain customized support information like the serial number etc. You may
send us this information together with a support request. It will help us to locate and solve your reported

problem.

The image above displays the IP module activity. From left to right the connected user(s), its IP address
(from which host the user comes from) and its activity status is displayed. RC means that the Remote
Console is open. If the Remote Console is opened in exclusive mode the term (exclusive mode) is

added. For more information about this option see the Section called Remote Console Control Bar in
Chapter 5. To display the user activity the last column contains either the term active for an active user or
30 min idle for an user who is inactive for a certain amount of time.

32

3-5.2 Event Log

The image above displays the log list including the events that are logged by the IP module.

3-5.3 Update FIrmware

3-7.3 Update Firmware

The IP module is a complete standalone computer. The software it runs is called rmware. The rmware of

the IP module can be updated remotely in order to install new functionality or special features.

A new rmware update is a binary le which will be sent to you by email or which you can download from
the supplier web site. If the rmware le is compressed (le sufx .zip) then you must unzip it before you
can proceed. Under the Windows operating system you may use WinZip from http://www.winzip.com/ for
decompression. Other operating systems might provide a program called unzip.

Before you can start updating the rmware of your IP module the new uncompressed rmware le has to be

accessible on the system that you use for connecting to the IP module.

33

Updating the rmware is a three-stage process:

1. Firstly, the new firmware file is uploaded onto the IP module. In order to do that you need to select the
file on your local system using the button “Browse” of the Upload Firmware panel. Once the firmware
file has been uploaded, it is checked whether it is a valid firmware file and whether there were any

transmission errors. In case of any error the Upload Firmware function will be aborted.

2. Secondly, if everything went well, you see the Update Firmware panel. The panel shows you the
version number of the currently running firmware and the version number of the uploaded firmware.
Pressing the button “Update” will store the new version and substitute the old one completely.

Warning

This process is not reversible and might take some minutes. Make sure the IP

module’s power supply will not be interrupted during the update process,

because this may cause an unusable card.

3. Thirdly, after the firmware has been stored, the panel will request you to reset the IP module manually.

Half a minute after the reset, the IP module will run with the new firmware version and should be
accessible. However, you are requested to login once again.

Warning

The three-stage rmware update process and complete consistency check are
making a mistake in updating the rmware almost impossible. However, only
experienced staff members or administrators should perform a rmware update.
Make sure the IP module’s power supply will not be interrupted!

3-5.4 Unit Reset

This section allows you to reset specic parts of the device. This involves the both keyboard and mouse,

the video engine and the IP module itself. Resetting the card itself is mainly needed to activate a newly

updated rmware. It will close all current connections to the administration console and to the Remote

Console.

The whole process will take about half a minute. Resetting sub devices (e.g. video engine) will take some

seconds only and does not result in closing connections. To reset a certain IP module functionality click on
the button Reset as displayed in the image above.

Note: Only the super user is allowed to reset the IP module.

34

4 Troubleshooting

The remote mouse doesn’t work or is not synchronous

Make sure the mouse settings in IP module match the mouse model. There are some circumstances where

the mouse synchronization process could behave incorrectly, refer to Sections 2.4.1 & 3.5.22 for further

explanation.

The video quality is bad or the picture is grainy

Try to correct the brightness and contrast settings (see Sections 5.4.1 & 6.5.3) until they are out of a range
where the picture looks grainy. Use the auto adjustment feature to correct a ickering video.

Login on IP module fails.

Was the correct combination of user and password given? On delivery, the user ”super” has the password
”pass”. Moreover your browser must be congured to accept cookies.

The Remote Console window can’t connect to IP module.

Possibly a rewall prevents access to the Remote Console. Make sure the TCP port

numbers 443 or 80 are open for incoming TCP connection establishments.

No connection can be established to IP module.

Check whether the network connection is working in general (ping the IP address of IP module). If not, check
network hardware. Is IP module powered on? Check whether the IP address of IP module and all other IP
related settings are correct! Also verify that all the IP infrastructure of your LAN, like routers etc., is correctly
congured. Without a ping functioning, IP module can’t work either.

Special key combinations, e.g. ALT+F2, ALT+F3 are intercepted by the console system and not

transmitted to the host.

You have to dene a so-called ’Button Key’. This can be done in the Remote Console settings.

In the browser the IP module pages are inconsistent or chaotic.

Make sure your browser cache settings are feasible. Especially make sure the cache settings are not set to

something like ”never check for newer pages”. Otherwise IP module pages may be loaded from your browser

cache and not from the card.

Windows XP doesn’t awake from standby mode

This is possibly a Windows XP problem. Try not to move the mouse while XP goes in standby mode.

Can’t upload the signed certicate in MacOS X

If an ’internal error’ occurs while uploading the signed certicate either change the extension of the le to .txt
or add a le helper using the Internet Explorer preferences for this type of le. Make sure that the encoding is

plain text and the checkbox ’use for outgoing’ is checked. Another possibility is to use a Mozilla based browser.

Every time I open a dialog box with some buttons the mouse pointers are not synchronous anymore

Please check, if you have an option like ”Automatically move mouse pointer to the default button of dialog

boxes” enabled in the mouse settings of the operating system. This option needs to be disabled.

6 Addendum

A. Key Codes

The table below shows the key codes used to denes keystrokes or hotkeys for several functions. Please note

that these key codes do not represent necessarily key characters that are used on international keyboards.
They name a key on a standard 104 key PC keyboard with an US English language mapping. The layout for

this keyboard is shown in the image below. However, most modier keys and other alphanumeric keys used
for hotkey purposes in application programs are on an identical position, no matter what language mapping
you are using. Some of the keys have aliases also, means they can be named by 2 key codes (separated by
comma in the table).

E. Bandwidth Consumption

The precongured network speed selection simply results in a different Compression and Color Depth
conguration in order to match the different bandwidth limitations of the network type (UMTS, ISDN, etc.)

The following suggested network bandwidth planning table for IP MODULE installation is from the test results
with 3D-Labyrinth screen saver at Resolution 800x600, the worst case consuming the highest network

bandwidth.

Compression

Video Optimized Video Optimized 8 bit 3.0 - 3.3 MB/s

Video Optimized
(high color)

LAN (high color) 0 (no compression) 16 bit 1.0 - 1.3 MB/s Uncompressed video data

LAN 0 (no compression) 8 bit 500 - 700 kb/s Uncompressed video data

DSL 2 8 bit 110 - 140 kb/s Slower video because of compression

UMTS 4 8 bit 80 - 100 kb/s Slower video because of compression

ISDN 128k 6 4 bit 20 - 30 kb/s 16 colors

ISDN/Moden V.90 7 2 bit 13 - 17 kb/s Gray scale

GPRS/HSCSD 8 2 bit 5 - 7 kb/s Gray scale
