The Remote Console is the redirected screen, keyboard and mouse of the remote host system to which LARA is attached. The Web browser which is used for accessing LARA has to supply a Java Runtime Environment version 1.1 or higher. The Remote Console will behave exactly the same way as if you were sitting directly in front of the screen of your remote system. -

LARA defines a new class of remote KVM access devices (see Figure 2.1). LARA combines digital remote KVM access via IP networks with comprehensive and integrated system management. LARA offers convenient, remote KVM access and control via LAN, Internet, or ISDN. It captures, digitizes, and compresses video and transmits it with keyboard and mouse signals to and from a remote computer. - Page 18 LARA is a fully configured stand-alone product consuming one quart of a 1U 19” rack mount chassis space. Up to four LARA devices can be mounted in 1 U chassis using the 19” rack mount kit (Item No: 8400200) Each LARA (Item No: 8400000) is shipped with: 1.

8. Check the cabling: finally, there are four cables connected to the jumper connector on the bracket. Now, connect the bracket to the LARA serial port 2 using the supplied SUB-D 9 to SUB-D 9 connector. Please refer to the manual of the Peppercon external power switch option or a third party external power option to connect those external devices either to the Peppercon Reset/Power Connector or to the serial interface on the rear side of LARA. - Page 26 The UTP wire pairs and configuration for 100BASE-TX cable are identical to those for 10BASE-T cable when used with Category 5 UTP cable. The rear side of LARA contains two RJ-45 connectors. The upper connector, marked as ’ISDN’ is used to connect LARA to an ISDN network, using a standard ISDN cable.

The Remote Console window is a Java Applet that tries to establish its own TCP connection to LARA. The protocol that is run over this connection is not HTTP or HTTPS but a protocol called RFB (Remote Frame Buffer Protocol). Currently RFB tries to establish a connection to port number 443. - Page 36 This option will be available only with a Java Virtual Machine version number of 1.3 or higher.

It is possible to select the number of ports the connected KVM uses. Each port may get a name assigned. In order to provide KVM port switching through LARA, key combinations have to be defined for the ports. -
Page 48: Kvm Settings
If an external power option is enabled it is additionally possible to assign a port of this control for power switching to each KVM port (see Section 5.4.1 on page 32). The user and group management of LARA is based on configurable users and groups. Each user or group may have different permissions. -
Page 49: User/Group Management
Upon delivery, each LARA is pre-configured with a supervisor user called ‘super’ having the pass- word ‘lara’. Make sure to change the super user password immediately after you have installed and firstly accessed your LARA. Figure 5.19 shows the User/Group Management panel of the LARA front-end. Its use will be described in Table and in the following text. - Page 50 In order to create a new group, enter a new and unused group name. The user management of LARA allows many different users. The following sections will describe how to add, change and delete users. Fill out the fields ‘New user name’, ‘Full user name’, ‘Password’ and ‘Confirm password’ as shown in Figure 5.19...

Page 51: User/Group Permissions Panel
A set of permissions is assigned to each user or group. Those rights are used to authorize access to certain LARA functionality for a particular user. By default the user ’super’ has all permissions. His permissions cannot be shrunk. A newly created user or group has no permissions. A user will inherit the permissions of all groups he belongs to. - Page 52 Next, clicking the ‘Update’ button will show the permission list of that user. Every right in the list has a permission value, which is explained in Table 5.8. Table 5.8.: LARA user and group permissions +view The user can view the entry.

In case you change the settings remotely make sure all the values are correct and you still have an option to access the LARA. - Page 54 The administrator may contact this server as well and pick up the same IP address belonging to his card. The administrator has to register a LARA that is supposed to take part in the service with the Dynamic DNS Server. He will get an approved nickname and password in return to the registration process.

3. Enable Dynamic DNS and change the settings according to your needs (see Table 5.10 on the next page). Note: LARA has its own independent real time clock. Make sure the time setting of LARA is correct. This can be achieved by configuring a timeserver (see Figure 5.21 on page 41) Note: LARA registers itself to the Dynamic DNS server slightly different from the time configured. - Page 56 Dynamic DNS Server. Spaces are not allowed in the Nickname! Check time LARA card registers itself in the Dynamic DNS server at this time.

LARA 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 LARA’s serial interface (refer to Figure on page 10).

Page 60: Isdn Settings
In addition to the standard interfaces, LARA offers remote access using an ISDN connection . Logically, connecting to LARA using an ISDN line means nothing else than building up a dedicated point to point connection from your console computer to LARA. With other words, LARA acts as an Internet Service Provider (ISP) to which you can dial in. - Page 61 Table 5.14 – continued from previous page Enable hang-up timer If you want LARA to hang up an incoming connection, you have for incoming calls to check this box.

- Page 70 However, it is possible to generate and install a new certificate that is unique for a particular card. In order to do that, LARA is able to generate a new cryptographic key and the associated so called Certificate Signing Request that needs to be certified by a so called certification authority (CA).

3. Upload the certificate to LARA using the ‘Upload’ panel as shown in Figure 5.34. Figure 5.34.: SSL Certificate Signing Request After completing these three steps, LARA has its own certificate that is used for identifying the card to its clients. -

Important Note: If you destroy the CSR on LARA there is no way to get it back! In case you deleted it by mistake, you have to repeat the three steps. The reset panel (see Figure 5.35) allows you to reset LARA. This function is mainly needed to activate a newly updated firmware. - Page 73 Telnet interface is entirely controlled with the according functions of the Web interface. Once you have successfully logged in LARA will present you the command line where you can enter according management commands. In general, the Telnet interface supports two operation modes: the command line mode and the terminal mode.
