9 Configuration

9.1 Network configuration using PSetup utility

The Factory default settings for the IP-KVM unit are as below:

DHCP: Disable

Default IP address: 192.168.0.70

Default Net Mask: 255.255.255.0

If DHCP mode is enabled (IP auto configuration = DHCP), the IP-KVM 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 IP-KVM. You can find the MAC

address labeled on the bottom side of the metal housing.

There is a Network Setup Software tool (PSetup) for setting up the network

configuration (IP address, Subnet mask, DHCP, etc). It is useful when you want to

change the network settings or you will not be able to access to the unit due to not

knowing the network settings of the unit. In this case, you can view or change the

settings via this utility.

IP-KVM 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 IP-KVM on a network that enables DHCP, you can use

the PSetup to find out the IP-KVM’s IP.

(1) Plug Ethernet cable to IP-KVM. IP-KVM will get an IP via DHCP.

(2) Using PSetup to look for IP-KVM.

a. Click Refresh Devices button to detect connected devices

b. Select MAC address of the IP-KVM in “Device MAC address” box. You

can find the MAC address labeled on the bottom side of the IP-KVM

unit. MAC address is detected as connection from computer and

IP-KVM is valid through USB or network.

c. Click Query Device to find the IP configuration on the right panel.

Notes:

 BOOTP, a static configuration protocol, uses a table that maps

IP addresses to physical addresses.

 DHCP, an extension to BOOTP that dynamically assigns

configuration information. DHCP is backward compatible with BOOTP.

-29-

Set up a fixed IP

a. Setup “IP auto configuration” as “None” ; setup IP address

and Subnet mask

b. Enter Super user login and password for Authentication

(default : super/pass)

c. Click Setup Device. If super login was authenticated,

it’ll show “Successfully configured device”.

Otherwise it’ll show “Permission Denied”.

-30-

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 (confirm)

Re-type the new password for the super user for confirmation.

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

otherwise press the “Cancel” button.

9.2 Configuration Setup via Serial Console

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

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

be configured with the parameters given in Table below.

Parameter Value

Bits/second 115200

Data bits 8

Parity No

Stop bits 1

Flow Control None

When configuring with a serial terminal, e.g., Hyper Terminal, reset the IP-KVM

and immediately press the “ESC” key. You will see some device information, and

a “=>” prompt. Enter “config”, press “Enter” key and wait for a few seconds for the

configuration questions to appear.

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 configuration: None

IP address: [192.168.0.70]

Net mask: [255.255.255.0]

Gateway: [0.0.0.0] -- (0.0.0.0 for none)

-31-

IP auto-configuration

With this option, you can specify whether the IP-KVM 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 IP-KVM. 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.

9.3 Keyboard, Mouse, and Video configuration

Between the IP-KVM 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.

9.3.1 IP-KVM keyboard settings

The IP-KVM 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-KVM Web front-end for details.

9.3.2 Remote Mouse Settings

A common seen problem with KVM devices is the synchronization

between the local and remote mouse cursors. The IP-KVM addresses

this situation with an intelligent synchronization algorithm. There are two

mouse modes available on the IP-KVM:

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.

-32-

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.

9.3.3 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.

9.3.4 Host system mouse settings

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

Note: The following limitations do not apply in case of USB and Mouse

Type “Windows >=2000, MacOS X”.

-33-

While the IP-KVM 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.

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.

9.3.5 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-KVM 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.

9.3.6 Recommended Mouse Settings

For the different operating systems we give the following advices:

MS Windows

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.

-34-

9.3.7 Video Modes

The IP-KVM 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-KVM may not be able to detect

them. We recommend using any of the standard VESA video modes,

instead.

10 Usage

10.1 Prerequisites

The IP-KVM 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-KVM

environment can be entirely managed using a standard web browser. You

can access the IP-KVM 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-KVM's serial port via a terminal mode.

The primary interface of the IP-KVM 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 1.5 or above. If

the browser has no Java support (such as on a small handheld device), you

are still able to maintain your IP-KVM using the administration forms displayed

by the browser itself.

For secure connection to the IP-KVM, we recommend the following

browsers versions:

■ Microsoft Internet Explorer version 6.0 or higher

■ Netscape Navigator 7.0 or Mozilla 1.6 or higher

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.

-35-

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 below shows the dialog box presented by the

Internet Explorer 6.0.

Figure 32: The Internet Explorer displaying the encryption key length

Newer web browsers generally support strong encryption on default.

10.2 Log in/out IP-KVM

10.2.1 Log in the IP-KVM

There are three levels of access privileges:

User Name Default Password Access Privileges

super

(factory default)

pass

(factory default)

Full access

administrator (user define)

Has partial rights to change
configuration of critical parts

user (user define)

Has permission to access basic function
of open Remote Console

The super user can add or remove a user easily via the web pages of

User Management > Users. Please refer to Addendum C for detailed

permission items for each user level.

Launch your web browser. Direct it to the address of your IP-KVM, 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

IP-KVM 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 IP-KVM>

When using a secure connection, type in:

https://<IP address of IP-KVM>

This will lead you to the IP-KVM login page as shown below

-36-

When connecting to the IPK-KVM unit, the IPK-KVM system (web server,

Telnet server or SSH server) will prompt user to enter the user name

and password in order to access to the system. If this is the first time

logging in, log in with the factory default username and password, you

will be prompted to change the default password

Warning

Please make sure to change the super user password immediatelly

after you have installed and accessed your IP-KVM for the first time.

Unchanging of the password for the super user is a severe secrurity

risk and might result in unauthorized access to the IP-KVM and to the

host system including all possible consequences!

Warning

Your web browser hast o accept cookies, or else login is not possible.

Navigation

Having logged into the IP-KVM successfully, the main page of the IP-KVM

appears. 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. Within the right frame, task-specific information is displayed that

depends on the section you have chosen before.

-37-

The Buttons of the front end:

Return to main page of IP-KVM access page

Open the IP-KVM remote console

Exit from the IP-KVM front end.

Warning

If there is no activity for 30 minutes, the IP-KVM will log out,

automatically. A click on one of the links will bring you back

to the login screen.

Remote Console Preview

Click on Click to open to start the remote console redirection

Click on Refresh to refresh the picture.

10.2.2 Log out from the IP-KVM

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.

-38-

10.3 The Remote Console

The Remote Console is the redirected screen, keyboard and mouse of the

remote host system that IP-KVM controls.

The Remote Console window is a Java Applet that tries to establish its own

TCP connection to the IP-KVM. The protocol that is running over this

connection is neither HTTP nor 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 IP-KVM 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.

10.3.1 Main Window of Remote Console

To open the KVM console either click on the icon Console or Remote

Control > KVM Console of the menu entry on the left or Click to open

of the console picture on the right.

-39-

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-KVM.

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 differenz 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.

10.3.2 Control Bar of Remote Console

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 33: 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).

-40-

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-KVM 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 1.5 or higher.

Options

To open the Options menu, click on the button “Options”.

Figure 34: Remote Console Options Menu

-41-

Notice:

If your IP-KVM enable Double Mouse mode, in order to keep remote and

local mouse pointers in sync, please take the following actions:

1. Disable the “Enhance pointer precision” and “Automatically move

mouse pointer to the default button in a dialog box” in the mouse

settings of host (target) computer OS.

2. If mouse pointers not in sync, please click on Sync button or Options

> Mouse > Handling > Intelligent Sync.

A short description of the options as 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.

Figure 35: Remote Console Exclusive Mode

-42-

• 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 algorithm execution. When you designate “Scale to

fit”, the remote video displaying is scaled to fit the size of Remote

Console window. (See page 41, top)

Figure 36: Remote Console Options Menu: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.

-43-

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 1.5 or above offers the full list.

Figure 37: Remote Console Options Menu:Cursor

• Video Settings

Opens a panel for changing the IP-KVM video settings. IP-KVM

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-KVM is active and passing through the

incoming signal from the host system.

-44-

The option Noise Filter defines how IP-KVM 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.

Video Settings through the remote console

Figure 38: Video Settings Panel

Brightness Controls the brightness of the picture

Contrast Controls the contrast of the picture

Clock

Defines 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 conjunction with the auto adjustment

procedure should be adequate for all common configurations. 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

Defines 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.

• 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-KVM, 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 filter for

VGA is setting too large.

• Soft Keyboard

Figure 39: 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.

-46-

Mapping

Used for choosing the specific language and country mapping of the

Soft-Keyboard.

Figure 40: Soft Keyboard Mapping

• 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 defined before. Choose one entry,

the command will be sent to the host system.

A confirmation 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.

Figure 41: Remote Console Confirmation Dialog

-47-

• Encoding

These options are used to adjust the encoding level in terms of

compression and color depth. They are available only when

"Transmission Encoding" is determined manually (select Manually

in KVM Settings > User Console > Transmission Encoding of

web page).

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.

-48-

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 42: Encoding Compression

The next two options allow you to set the compression level to a

predefined level OR to set a level for "lossy" compression. This

compresses well, but leads to degradation in image quality level for

"lossy" compression. This compresses well, but leads to degradation

in image quality.

Figure 43: Predefined Compression

-49-

Figure 44: Lossy 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 45: Encoding Color depth

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 IP-KVM will not have to do any

video compression. In total, this will lead to less transfer time of

the motion picture.

-50-

10.3.3 Status Line of Remote Console

Status line

Shows both console and the connection state. The size of the remote

screen is displayed. Figure 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.

Figure 46: Status line

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.

Figure 47: Status line transfer rate

For more information about Monitor Only and Exclusive Access settings,

see related sections.

-51-

11 Menu Option

11.1 Remote Control

The Remote Console is the redirected screen, keyboard and mouse of the

remote host system that IP-KVM controls. The Remote Console window is a

Java Applet that tries to establish its own TCP connection to the IP-KVM.

Starting the Remote Console opens a new window displays screen movement

of host system, with its size automatically adjusted to optimum. Keyboard and

mouse are redirected to control the host system simultaneously. A slight delay

may present depending on the bandwidth of network.

11.1.1 KVM Console

Figure 48: KVM Console

To open the KVM console either click on the icon Console or Remote

Control > KVM Console of the menu entry on the left or Click to open

of the console picture on the right.

-52-

11.1.2 Telnet Console/SSH Console

In general, the Telnet or SSH 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 is activated (if the serial settings

were configured accordingly). All inputs are redirected to the device on

serial port and its answers are displayed on the Telnet interface.

In order to log in with Telnet or SSH, you have to enable the access

settings from

Device Settings > Network.

Telnet Console

The IP-KVM 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 IP-KVM

host machine is using a text mode screen resolution.

-53-

To log in Telnet Console by one of the following way:

1. clicking Remote Control > telnet Console

Figure 49: Telnet Console

2. or telnet command as required by the Telnet client, for instance in

a UNIX shell: telnet 192.168.0.70

3. or run the SSH-supported terminal emulation program

(such as PuTTY).

Replace the IP address by the one that is actually assigned to the

IP-KVM. 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-KVM a command line will

be presented and you can enter according management commands.

-54-

Key in help to list all available commands.

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 RS-232 serial

port. This mode provides Serial over IP functin. The key

sequence ESC + exit switches back to the command mode.

-55-

SSH Console

The IP-KVM supports SSH security protocol. The SSHv2 will encryption

the transferred data so as to keep the data communication secured.

Basically, the SSH’s configuration interface is the same as Telnet console’s,

except that SSH is data encrypted and secured. Please run the

SSH-supported terminal emulation program (such as PuTTY).

-56-

11.1.3 Remote Wakeup

The IP-KVM provides the remote power wakeup function, which can

remotely wake up the sleeping computer. With this feature, the

computers that are not in use for now can be shut down and remotely

wake up the computer when want to use it, and thus save the power

energy.

Settings on target computer:

In order to be waked up, some settings have to be done on the target

computer:

1. BIOS setting:

Have the wake up function in BIOS Enabled

Note: the naming in BIOS varies depending on the BIOS type, it may

be Wake On LAN/PME, PME Event Wake Up, or Power On By PCI

Device.

-57-

2. Windows Settings:

Enter the Properties of Local Area Connection.

Make sure Wake on Magic packet is Enable.

-58-

Make sure the following two items are selected.

Settings on IP-KVM:

The control can be easily set up from the web page.

1. Click on Remote Control > Remote Wakeup to bring up the

configuration page.

2. Click on More entries to add additional controlled target

3. Key in the server description and the server’s IP address

4. Click on Get MAC to get the corresponding MAC address of the server

5. Click on Apply to save the entry

6. Click on Reset to defaults if want to clear all entries

-59-

11.2 Virtual Media

The IP-KVM provides a powerful capability called Virtual Media (or

Virtual Disk). Using the USB port, the IP-KVM can present either a local

floppy disk image or a redirected remote CD/DVD-ROM image to the

target computer. This can allow system recovery in conditions as bad as

having local disks down and no primary network connection. With

Floppy Disk Image, the user can upload an image to the IP-KVM’s

memory, which then emulates a locally attached floppy drive. With

CD/DVD-ROM Image, a Windows or other SAMBA share can emulate a

locally attached CD/DVD-ROM, for instance to update software.

Drive Redirection allows you to share (redirect) your local drive (floppy

drives, hard disks, CD ROMs and other removable devices like USB

sticks) with the remote system over a TCP network connection. Thus,

with Drive Redirection, you can use a virtual disk drive on the remote

computer instead of an image file. It is also possible to enable a remote

machine to write data to your local disc.

Before go ahead with this setup, both remote user computer and local

computer (the one connected with the IP-KVM unit) would have to have

Operating System Win2000, XP or above. This function would not work on

other platforms at this moment.

Before using Virtual Media, please connect the USB cable from IP-KVM to

host computer. After connecting the USB cable, you can see a

“Removable Disk” on the host computer. Below is the host computer

screen (the computer which connected with IPKVM).

-60-

11.2.1 Drive Redirection

The Drive Redirection is another possibility to use a virtual disc drive on

the remote computer. With Drive Redirection you do not have to use an

image file but may work with a drive from your local computer on the

remote machine. The drive is hereby shared over a TCP network

connection. Devices such as floppy drives, hard discs, CD-ROMs and

other removable devices like USB sticks can be redirected. It is even

possible to enable a write support so that for the remote machine it is

possible to write data to your local disc

Figure 50: Options of Drive Redirection

Please note that Drive Redirection works on a level which is far below the

operating system. That means that neither the local nor the remote

operating system is aware that the drive is currently redirected, actually.

This may lead to inconsistent data as soon as one of the operating

systems (either from the local machine, or from the remote host) is writing

data on the device. If write support is enabled the remote computer might

damage the data and the file system on the redirected device.

-61-

On the other hand, if the local operating system writes data to the

redirected device the drive cache of the operating system of the remote

host might contain older data. This may confuse the remote host’s

operating system. We recommend to use the Drive Redirection with care,

especially the write support.

Disable Drive Redirection

To disable the function of Drive Redirection.

Force read-only connections

If enabled the Write Support for the Drive Redirection is switched off. It is

not possible to write on a redirected device.

Click Apply to submit your changes.

11.2.2 Virtual Drive

Figure 51: USB mass storage option

Set this option to disable the mass storage emulation (and hide the virtual

drive) if not mounting a image file or drive to the host system. To set this

option, press the button “Apply”.

Note: If unset, and no file image will be found it may happen that the host

system will hang on boot due to changes in the boot order, or the

boot manager (LILO, GRUB). This case was reported for some

Windows versions (2000, XP), other OS might not be fully excluded.

This behavior depends on the BIOS version used in that machine.

-62-

11.2.3 CD/DVD Image

Use Image on Windows Share (via SAMBA)

To include an image from a Windows share, select “CD/DVD Image” from

the submenu.

Figure 52: Virtual Media - CD-ROM Image

Share host

The server name or its IP address (the PC that shares out the image file).

On Windows 95, 98 and Windows ME do not specify the IP address but

the server name ("NetBIOS Name").

Share folder name

The name of the share to be used.

Image file name

The image file name on the share folder.

User (optional)

If necessary, specify the user name for the share named before.

If unspecified and a guest account is activated, this guest account

information will be used as your login.

Password (optional)

If necessary, specify the password for the given user name.

-63-

Notes:

1. The output image extension file name has to be ‘iso’, e.g.

CD-Rom_vir.iso.

2. You may create an ISO image size up to 650Mb (for CD-ROM). This

drive would be in read-only mode and would not allow you to write any

information on this drive but copying only. This drive would be bootable

under DOS mode if the motherboard/BIOS on the host computer

supports USB BOOTABLE function. For emulating DVD Drive, please

use Drive Redirection function.

3. The above information has to be given from the point of view of IP-KVM

with correct IP address and device name. Administrative permission is

required as regular user may not have the right to access. Please login

as a system administrator (or as “root” on UNIX systems).

4. The specified image file is supposed to be accessible from the IP-KVM.

The information above has to be given from the point of view of the

IP-KVM. It is important to specify correct IP addresses, and device

names. Otherwise, IP-KVM may not be able to access the referenced

image file properly, leave the given file unmounted and will display an

according error message, instead. So, we recommend to state correct

values and repeat this step if necessary.

5. Furthermore, the specified share has to be configured correctly.

Therefore, administrative permissions are required. As a regular user

you may not have these permissions. You should either login as a

system administrator (or as “root” on UNIX systems), or ask your

system administrator for help to complete this task.

Operation Procedures:

1. Please run Nero or any CD/DVD imaging tool to create

CD/DVD ISO image.

2. Please create a folder and share this folder in the PC that shares out

the image file. Copy the CD/DVD ISO image file to this sharing folder.

(Please make sure password has to be setup with the authorized user

during Sharing => Permission settings)

-64-

MS Windows

Open the Explorer, navigate to the directory (or share) and press the

right mouse button to open the context menu. Select Sharing to open

the configuration dialog

■ If necessary, adjust the permissions (Permissions button).

■ Click OK to set the options for this share.

UNIX and UNIX-like OS (UNIX, Solaris, Linux)

If you like to access the share via SAMBA, SAMBA has to be

set up properly. You may either edit the SAMBA configuration

file/etc/samba/smb.conf or use the Samba Web Administration Tool

(SWAT) or WebMin to set the correct parameters.

Also looking at the man-entry of smb.conf is very helpful.

-66-

3. Fill in the sharing information on Image on Windows Share,

click on the Set button.

4. If the Image file set successfully.

5. Open the remote console and you can see the virtual CD

as below picture.

-67-

11.2.4 Floppy Disk

Figure 55: Virtual Media - Floppy Disk

The maximum image size is limited to 1.44MB. To use a larger image mount this

image via Windows Share (or SAMBA) (see the Section called Use Image on

Windows Share (via SAMBA) for details)

Operation Procedures:

1. You need to create the floppy image file first (Please refer to the section

“Creating a floppy image”). For this example, we use RawWrite software

(or any other image-creator software) to create floppy image. Please

use licensed software for this purpose.

2. You can find an image file saved at desire destination after you created

it with RawWrite.

3. Open the browser to log into the IP-KVM. Click Virtual Media > Floppy

Disk. Click the Browse button to choose the image file.

Click on the button Upload to initiate the transfer of the chosen

image file into the IP-KVM module’s on-board memory

-68-

4. After you uploading the image file, you will see the information below.

5. Open the remote console and you will see a virtual Floppy drive is

created on the host computer that connect to IP-KVM.

You may create a floppy image size up to 1.44Mb. This drive would be

in read-only mode and would not allow you to write any information on

this drive but copying only. This drive would be bootable under DOS

mode if the motherboard/BIOS on the host computer supporting USB

BOOTABLE function.

Notes:

1. If using other image-creator software, the output image extension file

name has to be ‘img’, e.g. floppy_vir.img.

2. The uploaded image file will be kept in the onboard memory of the

IP-KVM until the end of the current session, as you logged out, or

initiated a reboot of the IP-KVM

-69-

11.2.5 Creating an Image

11.2.5.1 Creating a Floppy Image

MS Windows

You can use the tool “Raw Write for Windows”. You can get the

RawWrite software from the website

http://www.chrysocome.net/rawwrite.

Figure 56: RawWrite for Windows selection dialog

From the menu, select the tab “Read”. Enter (or choose) the name

of the file in which you would like to save the floppy content. Click

on the button “Copy” to initiate the image creation process.

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.).

-70-

11.2.5.2 Creating a CD/DVD ISO Image

MS Windows

To create the image file, use your favorite CD imaging tool. Copy

the whole contents of the disc into one single image file on your

hard disk.

For example, with “Nero” you choose “Copy and Backup”. Then,

navigate to the “Copy Disc” section. Select the CD-ROM or DVD

drive you would like to create an image from. Specify the filename

of the image, and save the CD-ROM content in that file.

Figure 57 Nero selection dialog

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 CD-ROM image file, copy the contents of the CD-ROM

to a file. You can use the following command:

dd [ if=/dev/cdrom ] [ of=/tmp/cdrom.image ]

dd reads the entire disc from the device /dev/cdrom, and saves the

output in the specified output file /tmp/cdrom.image. Adjust both

parameters exactly to your needs (input device etc.).

-71-

11.2.6 Making a Drive Redirection

The operation procedures to make a drive redirection are as follows.

1. Run Remote Control > KVM Console.

2. Click on the “Floppy” icon

You will see the Driver Redirection window as below

Figure 58: Built-in Java Drive Redirection

-72-

3. You can either redirect a local drive (only available under Windows) or

redirect an ISO CD/DVD image.

3a. If click on Connect Drive

Select the drive to be redirected and click OK.

Select the drive you would like to redirect. All available devices

(drive letters) are shown here. Please note that the whole drive is

shared with the remote computer, not only one partition. If you have

a hard disc with more than one partition all drive letters that belong

to this disc will be redirected. The Refresh button may be used to

regenerate the list of drive letters, especially for an USB stick.

Write Support

This feature may be enabled here. Write support means that the

remote computer is allowed to write on your local drive. As you can

imagine, this is very dangerous. If both the remote and the local

system try to write data on the same device, this will certainly

destroy the file system on the drive. Please use this only when you

exactly know what you are doing.

Device Authentication

The factory default Username is “super” and the default Password is “pass”.

Click Connect to redirect drive

Warning

Please be cautious that if “Allow Write Support” is

selected, all data on the shred media might be

Warning

1. Drive Redirection is only possible with Windows 2000 or

later versions.

2. The Drive Redirection works on a low SCSI level and the SCSI

protocol cannot recognize partitions; therefore the whole drive

selected will be shared instead of any particular partition.

3. While connecting to a legacy KVM switch, please select PS/2

mouse for Keyboard/Mouse setting from webpage. Otherwise

you will not be able to use Hot-key.

Select the ISO image file and click Open

4. Finally the established Drive Redirection connection will be displayed

Open My Computer. The virtual drive appears on the remote

host PC window.

-74-

The drive redirection software tries to lock the local drive before it is

redirected. That means that it tries to prevent the local operating system

from accessing the drive as long as it is redirected. This may also fail,

especially if a file on the drive is currently open. In the case of a locking

failure, you will be prompted if you want to establish the connection

anyhow. This should not be a serious problem when the note above is

respected. If the write support is enabled, a drive which is not locked

might be damaged by the Drive Redirection.

Clicking on the Disconnect button will disconnect the

Drive Redirection connection.

Please note that Virtual Drive creation is by Device manner not by

Partition. Which means it looks for I/O in BIOS and sends the

corresponding signal to host computer. This way, you are sending the

entire hard drive (may consist of ‘X’ numbers of partitions) and emulate

whatever number of partitions on host computer. You may also emulate

a DVD-Drive with the same procedure. However, this DVD-Drive Does

NOT support Bootable function like Floppy and CD-ROM emulation.

11.3 User Management

On an IP-KVM, each user name has settings and permissions associated with it.

Settings affect how the user interfaces with the Remote Console. Permissions

allow or forbid the user from performing various actions on the IP-KVM’s web

pages. A newly assigned user has permissions inherited from an assigned group,

if any, or individual permissions if no group is assigned

-75-

11.3.1 Change Password

Figure 59: Setting Password

Change password of currently logged in user:

Old Password: type in current password

New Password: type in new password

Confirm New Password: re-type new password for verification

Click “Apply” to submit your changes.

11.3.2 Users and Groups

There are three kinds of levels of user accounts:

■ Super -- Has all possible rights to configure the device

■

Administrator -- Has partial rights to change configuration

apart from critical settings

■

User -- Has permission to access basic function of

open Remote Console

You can choose the desired level from the selection box role.

The IP-KVM comes with 1 pre-configured user account that has fixed

permissions. The account “super” has all possible rights to configure the

device and to use all functions IP-KVM 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-KVM.

-76-

Existing users

Select an existing user for modification. 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.

Confirm password

Confirmation 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” ) – their kinds

can be shose from: super, administrator, or an regular user.

To create an user press the button Create. The Modify button changes

the displayed user settings. To delete an user press the button Delete.

Note: The IP-KVM is equipped with an host-independent processor and

memory unit which both have a 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-KVM at the same time. The memory

space that is available onto the IP-KVM mainly depends on the

configuration and the usage of the IP-KVM (log file entries etc.).

That’s why we recommend not to store more than 63 user profiles.

11.4 KVM Settings

-77-

11.4.1 User Console

The following settings are user specific. 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.

Figure 60: User Console Setting

-78-

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.

Transmission Encoding

The Transmission Encoding setting allows changing the image-encoding

algorithm that is used to transmit the video data to the Remote Console

window. It is possible to optimize the speed of the remote screen

processing depending on the number of users working at the same time

and the network bandwidth of the connection line (Modem, ISDN, DSL,

LAN, etc.).

Automatic detection

The encoding and the compression level is determined

automatically from the available bandwidth and the current content

of the video image.

Pre-configured

The pre-configured settings deliver the best result because of optimized

adjustment of compression and color depth for the indicated network

speed.

Manually

Allows to adjust both compression rate and the color depth individually.

Depending on the selected compression rate the data stream between the

IP-KVM and the Remote Console will be compressed in order to save

bandwidth. Since high compression rates consume more computing

power of IP-KVM, they should not be used while several users are

accessing the IP-KVM simultaneously.

The standard color depth is 16 Bit (65536 colors). The other color depths

are intended for slower network connections in order to allow a faster

transmission of data. Therefore compression level 0 (no compression)

uses only 16 Bit color depth. At lower bandwidths only 4 Bit (16 colors)

and 2 Bit (4 gray scales) are recommended for typical desktop interfaces.

Photo-like pictures have best results with 4 Bit (16 gray scales). 1 Bit color

depth (black/white) should only be used for extremely slow network

connections.

-79-

Remote Console Type

Specifies, 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 configured

this way. Use of the Sun JVM may also be forced (see 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 first 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 1.5 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.

-80-

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 define a new Button Key is as follows:

[confirm] <keycode>[+|-[*]<keycode>]*

“confirm” requests confirmation 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.

11.4.2 Keyboard/Mouse

Figure 61: Keyboard and Mouse Settings

-81-

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 extended by three additional windows keys,

“Generic 106-Key PC” for a Japanese keyboard, and “Apple Macintosh”

for the Apple Macintosh.

Keyboard timeout

Recommended 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.

Mouse Speed

• Auto mouse speed

Use this option if the mouse settings on host use an additional

acceleration setting. The IP-KVM 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 fixed 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-KVM is not

functioning under this setting.

• Absolute mouse scaling for MAC server

Use this option for MAC server.

To set the options, click on the button Apply.

-82-

11.4.3 Video

Figure 62: Video Settings

Miscellaneous Video Settings

• Noise filter

This option defines how the IP-KVM 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 change instantly but may lead to a constant amount of

network traffic 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)

When connecting the device directly to legacy Sun computer (with

composite sync as the video output, it may be possible that IP-KVM

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

.

-83-

11.5 Device Settings

11.5.1 Network

The Network Settings panel allows changing network related parameters.

Each parameter will be explained below. Once applied the new network

settings will immediately come into effect.

Warning

Changing the network settings of the IP-KVM 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-KVM.

-84-

Figure 63: Network Settings

IP auto configuration

With this option you can control if the IP-KVM 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 configuration is disabled.

Preferred host name

Preferred host name to request from DHCP server. Whether the DHCP

server takes the IP-KVM suggestion into account or not depends on the

server configuration.

IP address

IP address in the usual dot notation.

-85-

Subnet Mask

The net mask of the local network.

Gateway IP address

In case the IP-KVM should be accessible from networks other than the

local one, this IP address must be set to the local network router's IP

address.

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-KVM 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-KVM'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-KVM's HTTP server is listening. If left

empty the default value will be used.

Telnet port

Port number at which the IP-KVM's Telnet server is listening. If left

empty the default value will be used.

SSH port

Port number at which the IP-KVM SSH (Secure SHell) server is listening to.

If left empty the default value (port 22) will be used.

Bandwidth limitation

The maximum network traffic generated through the IP-KVM ethernet

device. Value in Kbit/s.

Enable Telnet access

This enables the Telnet function.

Enable SSH access

This enables the SSH (Secure Shell) function.

-86-

Disable Setup Protocol

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

protocol is a proprietary layer-2 MAC-based protocol to allow some

configuration software to detect IP-KVM devices in the network, even

without IP address, and then config network related settings to IP-KVM..

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-KVM manually to the values as

supported by the network device.

11.5.2 Dynamic DNS

Figure 64: Dynamic DNS

-87-

A freely available Dynamic DNS service (www.dyndns.org) can be

used in the following scenario.

Figure 65. Dynamic DNS Scenario

The IP-KVM 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-KVM 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-KVM 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-KVM.

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

• Make sure that the LAN interface of the IP-KVM is properly configured.

• Enter the Dynamic DNS Settings configuration dialog as shown in

Figure.

• 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 configured

DNS server IP address.

Dynamic DNS server

This is the server name where IP-KVM registers itself in regular intervals.

Currently, this is a fixed setting since only dyndns.org is supported for now.

-88-

DNS System

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

Hostname

This is the hostname of the IP-KVM 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.

Check time

The IP-KVM registers itself for initiating the IP address of IP-KVM 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-KVM.

Warning

The IP-KVM has its own independent real time clock.

Make sure the time setting of the IP-KVM is correct.

(see the Section Date And Time )

11.5.3 Security

Figure 66: Device Security

-89-

Force HTTPS

If this option is enabled access to the web front-end is only possible

using an HTTPS connection. The IP-KVM will not listen on the HTTP

port for incoming connections.

In case you want to create your own SSL certificate that is used to

identify the IP-KVM refer to the Section called Certificate.

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. If set to ”Try” the applet tries to

make an encrypted connection. In case connection establishment fails

for any reason an unencrypted connection will be used.

If set to “Force” the applet tries to make an encrypted connection with

certificate. An error will be reported in case connection establishment fails.

Group-based System Access Control

This is the IP filtering function, it keeps unauthorized hosts from

accessing to the IP-KVM by specifying IP filtering rules. It is important

to fully understand what an IP filter is. If you don't fully understand this,

you will get unexpected results against your original plan.

Chain rule

The Chain rule determines whether the access from the hosts is

allowed or not. It can be one of these two values:

 ACCEPT : access allowed

 DROP : access not allowed

The rule can be configured to apply to a particular Group level

(All, User, Super, Administrator).

When the IP-KVM receives a TCP packet, it will process the packet with

the chain rule depicted below. The process ordering is important; The

packet will enter the chain rule 1 first, if meet the rule then take action

directly, otherwise go to chain rule 2.

-90-

Figure 67: Chain Rules of IP Filtering

Check the “Enable Group based System Access Control” to edit the rules.

-91-

Users can add a new IP filtering rule by setting the properties at adding

line by Append or Insert. User can remove a rule by Remove or Delete.

Figure 68: IP Filter Settings

-92-

11.5.4 Certificate

Figure 69: Certificate Settings

The IP-KVM uses the Secure Socket Layer (SSL) protocol for any

encrypted network traffic between itself and a connected client. During the

connection establishment the IP-KVM has to expose its identity to a client

using a cryptographic certificate. The default certificate comes with

IP-KVM device upon delivery is for testing purpose only. System

administrator should not rely on this default certificate as the secured

global access mechanism through Internet.

However, it is possible to generate and install a new base64 X.509

certificate that is unique for a particular IP-KVM. In order to do that, the

IP-KVM is able to generate a new cryptographic key and the associated

Certificate Signing Request (CSR) that needs to be certified by a

certification authority (CA). A certification authority verifies that you are

the person who you claim you are, and signs and issues a SSL certificate

to you.

-93-

The following steps are necessary to create and install a SSL certificate

for the IP-KVM:

• Create a SSL Certificate Signing Request using the panel shown in

Figure. You need to fill out a number of fields that are explained below.

Once this is done, click on the button “Create” which will initiate the

Certificate 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 certification. You will get the

new certificate from the CA after a more or less complicated traditional

authentication process (depending on the CA).

• Upload the certificate to the IP-KVM using the “Upload” button as shown

in Figure below.

Figure 70: SSL Certificate Upload

Figure 71: CSR string

-94-

After completing these three steps, the IP-KVM has its own

certificate that is used for identifying the card to its clients.

Common name

This is the network name of the IP-KVM once it is installed in the user's

network (usually the fully qualified domain name). It is identical to the

name that is used to access the IP-KVM with a web browser (without the

“http://” prefix). In case the name given here and the actual network name

differ, the browser will pop up a security warning when the IP-KVM is

accessed using HTTPS.

Organizational unit

This field is used for specifying to which department within an organization

the IP-KVM belongs.

Organization

The name of the organization to which the IP-KVM 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 certification authorities require a challenge password to authorize

later changes on the certificate (e.g. revocation of the certificate). The

minimal length of this password is 4 characters.

Confirm Challenge Password

Confirmation of the Challenge Password

Email

The email address of a contact person that is responsible for the IP-KVM

and its security.

Warning

If you destroy the CSR on the IP-KVM there is no way to get it

back! In case you deleted it by mistake, you have to repeat the

three steps as described above.

-95-

Key length

This is the length of the generated key in bits. 1024 Bits are supposed to

be sufficient for most cases. Longer keys may result in slower response

time of the IP-KVM during connection establishment.

11.5.5 Serial Port

Figure 72: Serial Port

The IP-KVM Serial Settings allows you to specify what device is connected

to the serial port and how to use it.

Configuration or console login

Do not use the serial port for any special function, use it only for the

initial configuration.

Modem

The IP-KVM 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-KVM .

-96-

Logically, connecting to the IP-KVM using a telephone line means nothing

else than building up a dedicated point-to-point connection from your

console computer to the IP-KVM. In other words, the IP-KVM 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-KVM, make sure to configure your console computer accordingly. For

instance, on Windows based operating systems you can configure a dial-up

network connection, which defaults to the right settings like PPP.

The Modem Settings panel allows you to configure the remote access to

the IP-KVM 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-KVM 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.

Modem Init String

The initialization string used by the IP-KVM 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-KVM 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-KVM 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-KVM and your console computer. The default value will

work in most cases.

-97-

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-KVM.

11.5.6 Date/Time

Figure 73: Date / Time

This link refers to a page, where the internal real-time clock of the IP-KVM

can be set up. 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-KVM 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.

-98-

11.5.7 Event Log

Figure 74: Event Log

Important events like a login failure or a firmware 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-KVM. 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 file here.

List logging enabled

The common way to log events is to use the internal log list of the

IP-KVM . To show the log list, click on “Event Log” on the “Maintenance”

page.

-99-

Since the IP-KVM'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-KVM, all logging information is saved permanently and is

available after the IP-KVM has been started. If the IP-KVM 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

Define a NFS server, where a directory or a static link has to be

exported, to write all logging data to a file that is located there. To write

logging data from more than one IP-KVM devices to only one NFS

share, you have to define a file 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 filled with valid sources or you will get an

error message.

SMTP Logging enabled

With this option, the IP-KVM is able to send Emails to an address given

by the Email address text field in the Event Log Settings. These mails

contain the same description strings as the internal log file and the mail

subject is filled 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-KVM device and that needs no authentication at all

(<serverip>:<port>).

SNMP Logging enabled

If this is activated, the IP-KVM sends a SNMP trap to a specified

destination IP address, every time a log event occurs. If the receiver

requires a community string, you can set it in the appropriate text field.

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 fields with detailed

information about the occurred event. To receive this SNMP traps, any

SNMP trap listener may be used.

-100-

Here is an example of all generated event and its event group.

Warning

In contrast to the internal log file on the IP-KVM, the size of the

NFS log file is not limited. Every log event will be appended to

the end of the file so it grows continuously and you may have to

delete it or move it away from time to time.
