Increasing the reliability of network connections through link aggregation

In the default settings, you can use both network interfaces at the same time to access the web application from two different network segments, for example.

To increase the reliability, the network interfaces can be grouped through link aggre- gation. Only one interface is active within the group. Another interface only becomes active if the active interface fails.

We provide two different modes to monitor the interfaces:

 MII mode: The carrier status of the network interface is monitored through the

Media Independent Interface. This mode only checks the function of the network inter face.

 ARP mode: The address resolution protocol sends requests to an ARP target within the

network. The answer of the ARP target confirms both the functionality of the net work interface and the proper network connection to the ARP target.

If the ARP target is connected to the network but is temporarily offline, requests cannot be answered. Define multiple ARP targets to receive an answer from at least one target if an ARP target fails.

NOTE:

MII and ARP mode cannot be combined.

How to configure the settings of grouped network interfaces:

Special features for complex KVM systems

If you want different devices to communicate within a KVM system, use the identical Certificate Authority (see page 29) to create certificates for those devices.

The identical PEM file (see page 32) can also be used for all devices. In this case, all certificate features are identical.

Creating a Certificate Authority

A Certificate Authority enables the owner to create digital certificates (e. g. for the matrix switch DVICenter).

How to create a key for the Certificate Authority:

IMPORTANT:

If necessary, read the OpenSSL manual to learn how to create a coded key.

1. Enter the following command into the command prompt and press Enter:

openssl genrsa -out ca.key 4096

2. OpenSSL creates the key and stores it in a file named ca.key.

The following steps describe how to create keys that are not coded.

How to create the Certificate Authority:

1. Enter the following command into the command prompt and press Enter:

openssl req -new -x509 -days 3650 -key ca.key -out ca.crt

2. Now, OpenSSL queries the data to be integrated into the certificate.

The following table shows the different fields and an exemplary entry:

Field Example

If these three components are available separately, enter them successively to the Clear text entry before updating the certificate stored in the device.

1. Enter the following command(s) into the prompt and press Enter:

a. Linux

cat server.crt > gdcd.pem cat server.key >> gdcd.pem cat ca.crt >> gdcd.pem

b. Windows

copy server.crt + server.key + ca.crt gdcd.pem

2. The gdcd.pem file is created during the copying. It contains the created certificate and its key as well as the Certificate Authority.

Selecting an SSL certificate

By default, each G&D device with integrated web application stores at least one SSL certificate. The certificate has two functions:

 The connection between web browser and web application can be established via

an SSL-secured connection. In this case, the SSL certificate allows the user to authenticate the opposite side.

If the device’s IP address does not match the IP address stored in the certificate, the web browser sends a warning message.

ADVICE:

You can import a user certificate so that the device’s IP address

matches the IP address stored in the certificate.

 The communication between G&D devices within a system is secured via the

devices’ certificates.

IMPORTANT:

Communication between devices is possible only if all devices within a KVM system use certificates of the same Certificate Authority page 29).

Network functions of the devices

User authentication with directory services

In in-house networks, the user accounts of different users are often administrated by a directory service. The device can access such a directory service and authenticate users against the directory service.

NOTE:

If the Admin user account cannot be authenticated by the directory service,

the user account is authenticated by the device’s data base.

The directory service is exclusively used to authenticate a user. The user rights are assigned within a database of the KVM system. The following paragraphs describe the different scenarios:

 The user account exists within the directory service and the KVM system

The user can log in with the password stored in the directory service. After the login, the user is assigned with the rights of the correspondent account in the KVM system.

NOTE:

The password which the user used to log in, is taken over into the data-

base of the KVM system.

 The user account exists within the directory service, but not within the KVM system

A user that has been successfully authenticated against the directory service, but does not have an account of the same name within the database of the KVM sys tem, is assigned with the rights of the RemoteAuth user.

If required, change the rights of this particular user account to set the rights for users without a user account.

ADVICE:

Deactivate the RemoteAuth user to prevent users without user accounts

to log in to the KVM system.

 The user account exists within the KVM system, but not within the directory service

If the directory service is available, it reports that the user account does not exist. The access to the KVM system is denied to the user.

If the server is not available, but the fallback system is active (see below), the user can log in with the password that is stored within the KVM system.

IMPORTANT:

Mind the following safety instructions to prevent a locked or deactivated user from logging in to the system in case the connection to the directory service fails:

 If a user account is deactivated or deleted in the directory service, this action

can also be carried out within the user database of the KVM system.

 Only activate the fallback system in reasonable exceptional cases.

Network functions of the devices

ADVICE:

After the directory service has been selected, collect the settings of

the directory service server in the

Server settings.

IMPORTANT:

Mind the following safety instructions to prevent a locked or deactivated user from logging in to the system in case the connection to the directory service fails:

 If a user account is disabled or deleted in the directory service, this action

can also be carried out within the user database of the KVM system.

 Only activate the fallback system in reasonable exceptional cases.

How to configure the user account authentication:

NOTE:

If no directory service is applied, the user accounts are administered by the

device.

1. Use the tree view to click on KVM matrix systems > [name] > Matrix switches.

2. Right-click the device to be configured. Now, click the Configuration entry in the

context menu.

3. Click the Network > Authentication tabs and enter the following data:

Monitoring functions

The current monitoring values of all devices within the KVM system can be viewed in the device-specific branches (e.g. KVM matrix systems) as well as in the KVM Combina tions and Critical Devices branches of the tree view.

The various information regarding a device can either be displayed in individual values or in monitoring groups, which are sorted according to topic. The following exemplary figure shows the Status values and three different monitoring groups:

Figure 4: Detailed view of an exemplary monitoring table

Individual values (the Status value in the figure above) immediately show if the status is correct (green) or deviating from the normal operating value (red). The text in the col umn also provides information about the current status.

Monitoring groups allow you to group various individual values. The column of a monitoring group shows if all values are within range (green) or if at least one value is deviating from the normal operating values (red).

Clicking the arrow in the column opens a separate window, which displays the individual values of the group.

Marking messages from critical devices as read

Many messages require immediate actions from the administrator. Other messages (e.g. the break-down of the redundant power supply), however, point to possibly uncritical conditions.

In such a case, all peculiar values of a device can be marked as read, which causes the following:

 A device whose deviating values have been marked as read shows no blinking status

bar.

 The cells, info dialogues and monitoring windows of all “read” devices are high-

lighted in yellow.

 If a monitoring group contains critical values, which have been marked as read,

the column displays Error. In addition, the cell is highlighted in yellow.

NOTE:

The system only highlights values that have been deviating from the normal operating values at the time the function has been executed. The web application shows if another monitoring value of such a device deviates from the normal operat ing values.

Device monitoring via SNMP

The Simple Network Management Protocol (SNMP) is used to monitor and control computers and network devices.

Practical use of the SNMP protocol

A Network Management System (NMS) is used to monitor and control computers and network devices. The system queries and collects data from the agents of the moni tored devices.

NOTE:

An Agent is a program, which runs on the monitored device and detects its sta-

tus. Via SNMP, the detected data are transmitted to the Network Management System.

If an Agent detects a severe failure within the device, it can send a Trap packet to the Network Management System. This way, the administrator is directly informed about such occurrences.

Configuring the SNMP agent

How to configure the SNMP agent:

1. Use the tree view to click on KVM matrix systems > [name] > Matrix switches.

2. Right-click the device to be configured. Now click the Configuration entry in the context menu.

Efficient user group administration

User groups enable the creation of a shared right profile for several users with identical rights. Furthermore, the user accounts that are included in the member list can be grouped and therefore no longer have to be individually configured. This facili tates the rights administration within the matrix system.

If the rights administration takes place within the user groups, the user profile only stores general data and user-related settings (key combinations, language settings, …).

When initiating the matrix system, it is recommended to create different groups for users with different rights (e. accounts to these groups.

EXAMPLE:

ple, some users of the »Office« group are to be provided with the multi-access right, a respective user group can be created:

 Create a user group (e. g., »Office_MultiAccess«) with identical settings for the »Office«

group. The multi-access right is set to full. Assign the respective user accounts to this group.

 Create a user group (e. g., »MultiAccess«) and only set the multi-access right to Yes. In

addition to the »Office« group, also assign the respective user accounts to this group.

In both cases, the user is provided with the full effective right for multi-access.

Reducing the colour depth of the image data to be transmitted

In the default settings of a target module, the central module transmits the image information with a maximum colour depth of 24 bit to the user module.

Using a high resolution and displaying moving images can result in the user module “skipping” several images.

In such cases, reduce the colour depth if the image data to 18 bits, which reduces the data volume to be transmitted.
