8.4.  Thin Terminals

ThinLinc has support for several thin terminals, i.e. hardware built with the task of providing a thin client as primary design goal.

8.4.1.  eLux-based Thin Terminals (Fujitsu Futro et. al.)

ThinLinc has support for running the client on eLux-based thin terminals. This includes the Fujitsu Futro as well as NEXTerminal terminals such as the NEXceed. eLux is a modern embedded operating system which works well.

ThinLinc supports models that uses the eLux RP 5.x operating system. Microphone devices are known to work at least on the Futro models. However, make sure to disable "Sound in XDMCP sessions".

8.4.1.1.  Installing/Upgrading the ThinLinc Client on eLux

Below we will describe how to install and configure the ThinLinc client on terminals running eLux. For details on how to use the administrative tools (Scout and ELIAS) as well as on how to manually configure terminals without use of Scout, please refer to the eLux documentation available at http://www.myelux.com.

  1. Create a new firmware image including the ThinLinc client. This is done by copying the files thinlinc-client-* from the appropriate container directory in the Client Bundle to your ELIAS/Scout container directory.

    Note

    Some eLux distributions already include the ThinLinc client, rendering this step unneccesary.

  2. Add the ThinLinc client to your firmware image using ELIAS.

  3. Install the image on your clients using either Scout (for centrally-managed clients), or via http (for single clients).

  4. Configure your clients by adding an application of type Custom under the Local tab under Configuration on the client (or create a new application if using Scout). Set the application name to "ThinLinc" and the command line to tlclient. Check the "Application restart" and the "Start automatically after 0 s" checkbuttons to make sure the ThinLinc client is restarted after end of session, and that it is started automatically at boot.

    Note

    All commandline parameters accepted by the Native Linux client is also accepted by the client run on eLux (it's the same client). This means that server name, username, lockdown options etc. can be used on the commandline specified when configuring the client. An example commandline instructing the client to start with an empty username and to connect to <server name> is provided below.

    tlclient -u '' <server name>
    

    This configuration can be done either on the client, under the configuration tab in the starter, or centrally, using Scout, by adding an application in the Applications container in an appropriate organizational unit.

  5. Configure the starter not to start automatically by unchecking the checkbox in "Autostart Starter after 0 s" under Setup Desktop Advanced . Unchecking the "Enable" button for the Taskbar in the same location may also be a good idea to give users a cleaner environment.

    This configuration can be done either on the client, under the Setup tab in the starter, or centrally, using Scout.

  6. If custom configuration of the client, for example to support local drives, is needed, transfer a custom client configuration file (tlclient.conf) to /setup/thinlinc/tlclient.conf on the eLux clients using the "Transfer files" functionality available in the properties of devices or organisation units in Scout (under the Files tab). The files are transferred when the client is restarted.

8.4.2.  HP ThinPro Terminals

HP ThinPro terminals are based on Ubuntu, and therefore one can use the DEB package provided in our ThinLinc Client bundle for this terminal.

8.4.2.1.  Manual installation/upgrade of ThinLinc Client

Below we will describe the process of manually installing the ThinLinc Client on Ubuntu based HP ThinPro Linux terminals.

  1. Use the tool "Administrator/User mode switch" to authenticate as administrator.

  2. Start an X terminal from the advanced tab in the control panel.

  3. Unlock the filesystem:

    # fsunlock

  4. Copy the ThinLinc Client .deb package from ThinLinc Client bundle onto a USB memory stick, and connect it to the terminal. Go into the directory which represents your connected USB device with command:

    # cd /tmp/tmpfs/media/my_usb_storage

    As an alternative, it is also possible to download the client package from a web server using the "wget" command.

  5. Install the ThinLinc Client package using Debian package manager command:

    # dpkg -i thinlinc-client*.deb

  6. Lock down the filesystem before closing the X terminal window:

    # fslock

  7. Reboot.

  8. Add a ThinLinc connection in the connection manager.

The HP "Connection Wizard" does not include an entry for ThinLinc. Press "Skip", then add a ThinLinc Connection in the "Connection Manager".

The default user and administrator share the same home directory, and it is therefore important to NOT start the ThinLinc Client as administrator the first time. This will make the ThinLinc Client configuration only accessible by administrator and not the default user.

On "zero" clients, the default server name is set when the ThinLinc connection type is selected. To change server name, temporarily switch to another connection type, then switch back to ThinLinc. Also, to configure the ThinLinc Client, enter an invalid username/password combination in the HP login dialog. Acknowledge the error. It is then possible to access the full ThinLinc Client interface.

8.4.3.  IGEL Universal Desktop

A client package for IGEL Universal Desktop terminals is provided. It is included in the directory client-igel in the Client Bundle. IGEL Universal Desktop is a modern embedded operating system which works well. Some editions includes a bundled ThinLinc client. We do not recommend this client. Instead, install the client as described below.

Note

Installation of our client package is only possible on IGEL terminals with the "Custom Partition" feature. Please ask your IGEL representative for more information.

8.4.3.1.  Installing/Upgrading the ThinLinc Client on IGEL terminals

Below we will describe how to install and configure the ThinLinc client on IGEL terminals, using the "Custom partition". You can use either the Universal Management Suite software running on a separate workstation, or the setup software installed on the terminal. You will need access to a web server which allows you to publish the client files.

  1. Edit the configuration of the terminal. Select System, Firmware Customization, Custom Partition.

  2. Under the Partition option, make sure that "Enable Partition" is checked. Enter a size, such as "100M". The partition must be at least 25 MiB. The upper limit depends on the hardware used. Make sure that the mount point is /custom.

  3. Under the Download option, press the star to create a new data source. Enter the URL to the web server where the ThinLinc client package definition is located. Example: http://www.example.com/client-igel/thinlinc-i686.inf

  4. Under Custom Application, press the star to create a new application entry. Use a Session Name such as "ThinLinc".

  5. Click on Settings. Enter the Icon name:

    /custom/thinlinc/icon.png
    

    To setup the client to use the terminals normal language, enter this Command:

    /custom/thinlinc/bin/tlclient
    

    To setup the client to use Swedish, use this Command:

    env LC_ALL=sv_SE.UTF-8 /custom/thinlinc/bin/tlclient
    

  6. Press OK to save the configuration.

8.4.4.  Dell Wyse-Enhanced SuSE Linux Terminals

A client Add-On for Dell Wyse-terminals running "Dell Wyse-Enhanced SUSE Linux" is provided in the Client Bundle, inside the client-wyse/ directory. For instructions on how to install or upgrade this package, please consult the Wyse Linux documentation.

The Dell Wyse client bundled is built and packaged for SUSE Linux Enterprise Thin Client 11 Service Pack 3 (sletc11sp3). Due to limitations of the package metadata, a package can only support one service pack version of SLETC11 at the same time.

8.4.5.  Other Thin Terminals

The ThinLinc client can be made to run on almost any Linux-based Thin Terminal as well as on some Windows-based appliances. Contact Cendio if you need help on a consultancy basis.
