Regulatory Compliance for Thin Clients

Basic EMC and Safety Requirements

Wyse appliances are compliant with the regulatory requirements in the regions listed below.

U.S.A.—FCC Part 15 (class B), cUL 60950

Canada—IC ICES-003, CAN/CSA-C22 No. 60950

Europe—EN 55022 (class B); EN 55024

Wireless Usage and Requirements

Radio transmitting type devices (RF module) are present in models with the wireless option. These devices operate in the 2.4 GHz band (i.e. 802.11B/G/N LAN & Bluetooth).

As a general guideline, a separation of 20 cm (8 inches) between the wireless device and the body, for use of a wireless device near the body (this does not include extremities) is typical. This device should be used more than 20 cm (8 inches) from the body when wireless devices are on and transmitting.

Some circumstances require restrictions on wireless devices. Examples of common restrictions include:

• When in environments where you are uncertain of the sanction to use wireless devices, ask the applicable authority for authorization prior to use or turning on the wireless device.

• Every country has different restrictions on the use of wireless devices. Since your system is equipped with a wireless device, when traveling between countries with your system, check with the local Radio Approval authorities prior to any move or trip for any restrictions on the use of a wireless device in the destination country.

• Wireless devices are not user-serviceable. Do not modify them in any way. Modification to a wireless device will void the authorization to use it. Please contact the manufacturer for service.

Device Power Supply

Use only the external power supply that comes with your zero client. For power and voltage ratings, see the serial number label or regulatory label on your device. For power adapter replacement, contact your Dell Service Representative. For proper replacement compare the labels on both zero client and power adapter to ensure that their voltages match.

WARNING: Use of any other power adapter may damage your zero client or the power adapter. The damage caused by an improper power adapter is not covered by warranty.

2 Getting Started: Quickly Learning the Basics

Use the following information to quickly learn the basics and get started using your thin client:

• "Logging In"

• "Using Your Desktop"

• "Configuring Thin Client Settings and Connections"

• "Connecting to Network and Session Services"

• "Connecting to a Printer"

• "Connecting to a Monitor"

• "Shutting Down, Restarting, and Suspending"

• "Additional Getting Started Details"

TIP: While it can be used in environments without central configuration for basic connectivity needs, Dell thin clients are designed to be centrally managed and configured using INI files. In general, it is recommended that you use central configuration to enable you to automatically push updates and any desired default configuration to all supported thin clients in your environment (see "Configuring Thin Client Settings Locally").

Logging In

TIP: On your initial connection to central configuration it is recommended that you connect using a “wired connection” (plug in the network-connected Ethernet cable to your thin client before starting the thin client) to obtain the configurations desired by the administrator (connections, system settings, required certificates and so on). This “wired connection” will also provide any wireless configurations provided by the administrator through the INI files. If you must initially connect to central configuration through wireless, use the Edit Wireless Connection dialog box (in the Computer menu, click Control Center > Network Connections > Wireless tab > Add) to create a wireless connection where you can enter the SSID and encryption configurations required/set up by the network administrator (see "Network Connections").

After your thin client starts and displays the log in screen, you can log in to your desktop using the default user name admin and the default password admin. It is highly recommended that you change the default password by using the User Administration dialog box in the Control Center (see "User Administration").

Configuring Thin Client Settings and Connections

While the use of INI files is recommended to configure thin client settings and connections available to users (see "Configuring Thin Client Settings Locally" and Reference Guide: Wyse ® Enhanced SUSE Linux Enterprise SP2 INI Files), you can use dialog boxes on a thin client to:

• Set up your thin client hardware, look and feel, and system settings (see "Configuring Thin Client Settings Locally").

• Configure and add connections to your Desktop for use (see "Configuring Connections Locally").

Connecting to Network and Session Services

Use the Network Manager icon, located on the right side of the Desktop, to display information about your network connection and to connect or disconnect.

Use the following guidelines:

• Click the Network Manager icon to display the Wired Network and Wireless Network menus. For example you can click the Network Manager icon, and then select an available wired or wireless network to use.

• Right-click the Network Manager icon to display the Enable Networking, Enable Wireless, Enable Notifications, and Connection Information options. For example, you can right-click the Network Manager icon, and then click Enable Wireless to remove the check and disable wireless.

• Hover your mouse pointer over the icon to view a message displaying the status (No Network Connection, Wired Network Connection Active, and Wireless Network Connection Active) and name of the network to which your thin client is connected. For example, connecting your thin client to a wired network (by attaching the network cable to your thin client) displays the Wired Network Connection Active status.

For wireless connections (802.11b/g/n Wireless LAN), you can click the Wireless Network Connection icon (or click the Network Manager icon) in the menu bar to see if a wireless network connection is available. You can click an available wireless network connection to open and use the Wireless Network Authentication dialog box. After authentication, the wireless network is available for use.

IMPORTANT: Currently, 802.1x configuration is supported only for Wired connections and Protected EAP (PEAP)/MSCHAPv2 password Authentication options using the Enable802 INI parameter (see "Network Connections").

TIP: For information on importing certificates that your network may require, see "Import Certificates."

Connecting to a Printer

To connect a printer to your thin client through a USB port, you will need a USB-to-printer adapter cable (not included). Before use, you may need to install the driver for the printer by following the printer driver installation instructions. For information on connecting to printers, see "Printing."


Connecting to a Monitor

Depending on your thin client model, connections to monitors can be made using either a VGA (analog) monitor port, a DVI (digital) monitor port, or a DisplayPort (digital) and the proper Dell monitor cables/splitters/adapters. For information on configuring dual display settings, see "Display."

TIP: For dual-monitor supported thin clients using a DVI to DVI/VGA splitter, the VGA monitor will be the primary monitor. For dual-monitor supported thin clients using a DisplayPort, the DisplayPort monitor will be the primary monitor.

INI (and Upgrade) Settings

Use the INI and Upgrade Network Settings dialog box (click INI Settings) to direct the thin client to the source (server location) of INI files and image updates.

CAUTION: It is recommended to obtain INI files through a DHCP server using DHCP options rather than through a static IP address. For information about how INI files and images are downloaded from the server, see "How to Set Up Automatic Configurations and Updates."

TIP: Dell devices also support INI updates through WDM’s DDC (see "Enhancing Your Experience with Dell Software" and "WDM (Agent Configuration)").


• Do not use INI files - Use this option when you want to use only locally configured settings (using the thin client dialog boxes available) and do not want to use available INI files on the network or local INI files.

• Use INI files from server only - Use this option when you want to use INI files from the specified server only (for example, you do not want to use local INI files or do not want to allow INI use when disconnected from the server for security reasons). When using this option you can direct the thin client to the server location through either of the following ways:

· DHCP Server - Select the Get INI and Upgrade server details via DHCP check box. The DHCP server will direct the thin client (using DHCP options) to the server location where the INI files and image updates reside.

· Manually entered server address - Clear the Get INI and Upgrade server details via DHCP check box and enter the static INI Settings (INI Server URL, and optionally the Username and Password of the server, if selecting the Server requires authentication check box).

• If server is available, use INI files from server only; otherwise use local INI files - Use this option when you want to use INI files from the specified server, however, local INI files can be used if that server is unavailable. When using this option you can direct the thin client to the server location through either of the following ways:

· DHCP Server - Select the Get INI and Upgrade server details via DHCP check box. The DHCP server will direct the thin client (using DHCP options) to the server location where the INI files and image updates reside.

· Manually entered server address - Clear the Get INI and Upgrade server details via DHCP check box and enter the INI Settings (INI Server URL, and optionally the Username and Password of the server, if selecting the Server requires authentication check box).


• Use local INI files only - Use this option when you want to use only local INI files and do not want to use available INI files on the network.TIP: INI files can be cached locally if using the EnableLocal and LocalCopy INI parameters; see Reference Guide: Wyse ® Enhanced SUSE Linux Enterprise SP2 INI Files.

• Image Upgrade Settings - You can click Image Upgrade Settings to configure the INI and upgrade network settings as described in "Configuring the Image Upgrade Options."

Configuring the Image Upgrade Options

Using the INI and Upgrade Network Settings dialog box, you can configure how the image on the thin client is updated if you manually configured the INI server URL as described in "INI (and Upgrade) Settings."

In the INI and Upgrade Network Settings dialog box, click the Image Upgrade Settings to open and use the Thin Client Settings dialog box.

· Base System Only - Only the base image is updated at each reboot.

· Add-ons Only - Only add-ons are updated at each reboot.

• Enter the Update Server URL. If the server from which the thin client updates requires authentication, select the Server required authentication check box and enter the Username and Password.

• Restore factory defaults when updating - When selected, removes all local-machine customizations when software is updated from the file server. This setting is enabled by default and is recommended. However, if you want to keep locally defined connections or custom changes to installed applications, you can clear this check box.TIP: In order to update with the Restore factory defaults when updating option disabled, you must have a properly set-up addons folder with a directory file that defines which software versions you want on the thin client. Moreover, it may take two full reboots to restore the latest software as well as your customizations.

• Force base system update - If you want to install the image and add-ons available on the file server regardless of whether or not they are the same as the currently installed image and add-ons on the thin client, select this check box.TIP: The Restore factory defaults when updating option and the Force base system update option are useful when you want to fully restore the unit to factory defaults. These options remove any customizations and install only the base image supplied by Dell.

• Click OK to return to the INI and Upgrade Network Settings dialog box.

Network Connections

Use the Network Connections dialog box (click Network Connections) to configure the settings you want for supported network connections. Use the Wired, Wireless, Mobile Broadband, VPN, and DSL tabs to view and manage (add, edit, and delete) the list of network connections configured on the thin client. By default, your thin client obtains information from the DHCP server about network connections (highly recommended), but you can manually enter connection information (provided by your network administrator) to connect to other networks (experienced users only).

IMPORTANT: Currently, 802.1x configuration is supported only for Wired connections and Protected EAP (PEAP)/MSCHAPv2 password Authentication options using the Enable802 INI parameter.

Supported seamless 802-1x authentication works with SuSE-based Linux thin clients by using Active Directory user credentials for Inner EAP. Thus, Active Directory Domain User Login to the thin client has been introduced for EAP-PEAP 802-1x authentication. NOTE: This section covers only the details of EAP-PEAP 802-1x authentication via INI (see Reference Guide: Dell® Wyse Enhanced SUSE Linux Enterprise SP2 INI Files). The following diagram depicts the major components involved and communication between each of the components in the 802-1x Linux thin client solution.


EAP-PEAP (MSCHAPv2) Authentication Workflow

When you take a SuSE-based Linux thin client out of the box and connect it to your network, the thin client will obtain Guest VLAN resources by default (that is, it should be able to reach Active Directory, DNS, and INI servers to fetch the INI configurations required for Active Directory Domain User Authentication, 802-1x, ImportCerts, and so on.

The following steps are involved in the 802-1x authentication:

1. When the thin client boots up, it remains in the Guest VLAN and downloads the ini configuration from the INI server.

2. The INI file must have the configurations for 802-1x, Active Directory server, and Domain and Import certs. If you are pushing a CA certificate via Wyse Device Manager (WDM), Imports Certs INI is not required, but you must be sure that the CA certificate name is correct in the 802-1x INI parameter (see Reference Guide: Dell®

Wyse Enhanced SUSE Linux Enterprise SP2 INI Files).

3. Once the INI is downloaded to the thin client, the user obtains the domain which is configured via the INI in the domain drop down list at the user GDM login screen.

4. The user must then select the domain, and enter the user domain credentials to log in to the thin client. Domain User authentication is performed against the AD server named in the INI configuration.

5. If the domain user login is successful and the correct CA certificate is available, then 802-1x authentication will begin (users will see the network progress icon on the taskbar) and the thin client will move to Authorized VLAN.If 802-1x authentication fails due to any wrong 802-1x configuration (or if the CA certificate has expired), the thin client will automatically fall back to Guest VLAN, with a notification message ("Failed to connect to trusted network. Please contact your system administrator") displayed to the user at the right corner of GNOME panel (taskbar).

6. When a user logs out or restarts the thin client, the thin client will again move to Guest VLAN by sending an EAPOL logoff to switch and disabling the 802-1x configuration at the Network Connections applet.

36 Chapter 3

The following figure illustrates the overall flow of 802-1x authentication.

Example of the INI Configuration for EAP-PEAP (MSCHAPv2) 802-1x Authentication

Power Management

Use the Power Management Preferences dialog box (click Power Management) to select On AC Power (actions and display), On Battery Power (actions and display for mobile thin clients), General (actions, notifications, and extras), and Scheduling (automatic wake-up) power preferences. Press the Power button to wake the thin client from standby or sleep mode.


SCEP Client Configuration

Use the SCEP Client Configuration dialog box (click SCEP Client Configuration) to direct the thin client to use automated certificate enrollment (SCEP offers a standard interface to communicate with a Certificate Authority).

SCEP (Simple Certificate Enrollment Protocol) is a PKI communication protocol which leverages existing technology by using PKCS#7 and PKCS#10. It includes several properties that allow it to do an automatic enrollment without manual interaction. The typical usage scenarios of SCEP are large network environments with many network devices that require automatic enrollment of certificates.

TIP: Enrollment and usage of SCEP generally follows the following work flow:1 -Obtain a copy of the Certificate Authority (CA) certificate and validate it.2- Generate a CSR and send it securely to the CA.3 - Poll the SCEP server in order to check whether the certificate was signed.4 - Enroll/re-enroll as necessary in order to obtain a new certificate prior to the expiration of the current certificate. 5 - Retrieve the CRL as necessary.


• Adding a SCEP Client Configuration Certificate - Click Add to open the SCEP Certificate Enrollment Settings dialog box, enter a Certificate Name (Certificate file name must be unique), SCEP Server URL, Enrollment challenge password, CA Distinguished Name, and then click OK to create a SCEP certificate entry for a CA enrollment. NOTE: After adding a certificate, the newly added certificate entries will be displayed in the SCEP Client Configuration dialog box.

• Editing a SCEP Certificate - Select a certificate from the list, click Edit, and configure the certificate settings.

• Deleting a SCEP Certificate - Select a certificate from the list, click Delete, and then confirm.

• Enroll a SCEP Certificate - Select a certificate from the list and click Enroll. After successful certificate enrollment, the Status column will display as Enrolled (in a case of failure, the Status column will display as Failed.

TCX USB Virtualizer

Use the TCX USB Virtualizer Configuration Utility dialog box (click TCX USB Virtualizer) to view and manage (add, edit, and delete) the list of current device classes (on the Configuration tab) and to view the list USB devices enabled or denied for use on the thin client (on the USB Devices tab). You can deny a device class, but still permit a USB device in that class to be used, by adding it to the Devices list of the Configuration tab.


• Enabling USB devices - Select the Enabled check box (default).

• Allowing or denying USB device classes - On the Configuration tab, select or clear the check box of a device class in the Devices list to allow or deny its use. For example, select Smart Card Devices to permit USB smart card devices to be used to log into virtual machines.

• Adding a USB device - On the Configuration tab, click Add to open the Add dialog box, enter a Device Name, select a class for the device from the Class list, enter the Sub Class, Vendor ID, Protocol, and Product ID, and then click Add. After you reboot your thin client, the name of the new device appears on the Configuration tab.TIP: You can obtain device Class, Sub Class, Protocol, Vendor ID, and Product ID information by plugging the device into the USB port of your thin client and viewing the information displayed in the USB Devices tab.

• Allowing or denying a USB device - After you add a USB device, its name appears on the Configuration tab. Select or clear a USB device check box to allow or deny its use.CAUTION: Use caution when using TCX USB Virtualizer on a terminal server, as allowing use of a USB device is global and not session restricted.

For information on the TCX USB Virtualizer component of Wyse TCX Suite software, see "Enhancing Your Experience with Dell Software."


User Administration

Use the User Administration dialog box (click User Administration) to view and edit passwords for all users (both built-in defaults and those defined through INI files) and to enable automatic login for a user (automatically log in a user at system start up). In addition, you can manage SSH root User password and login (using the SSH root User tab).

CAUTION: While this dialog box allows you to edit the passwords and automatic login for users of the thin client, you must use central configuration (INI files) to add or delete users beyond the built-in default users provided. In general, it is recommended that you use user.ini files to manage (add, edit, or delete) users for normal use cases. For example, a new user should be created through a user.ini file with the appropriate privilege level defined in the text file.

To edit a user password, select the change password check box you want, and then enter a new password in the New Password and Confirm Password boxes.

TIP: The Users tab can be a convenient way to locally change the password and enable automatic login for a specific user.

TIP: For information on shadowing a thin client, see "Administrators Only: Details on Using TightVNC Viewer for Remote Administration (to Shadow/Monitor a Thin Client)."

Administrators Only: Details on Using TightVNC Viewer for Remote Administration (to Shadow/Monitor a Thin Client)

TightVNC Server is installed locally on the thin client (see "VNC Server"). It allows a thin client to be shadowed/operated/monitored from a remote machine on which TightVNC Viewer is installed (TightVNC Viewer is available from the TightVNC Web site; it is also included as a component of WDM software and must be installed on the remote/shadowing machine before use).

TightVNC (Server and Viewer) allows a remote administrator to configure or reset a thin client from a remote location rather than making a personal appearance at the thin client site (VNC is intended primarily for support and troubleshooting purposes). TightVNC Server starts automatically as a service at thin client startup. The service can also be stopped and started by using the Services window (opened by clicking Start > Control Panel > Administrative Tools > Services).

Before an administrator on a remote machine (on which TightVNC Viewer is installed) can access a thin client (with TightVNC Server) the administrator must know the:

• IP Address (or valid DNS name) of the thin client that is to be shadowed/operated/monitored (see "Viewing System Information"). To obtain the IP address of an administrator thin client, hover the mouse arrow over the VNC icon in the system tray of the Administrator taskbar.

• Security Password of the thin client that is to be shadowed/operated/monitored (see "VNC Server").

66 Chapter 5

To shadow a thin client from a remote machine:

1. Open the New Tight VNC Connection dialog box (for example, Start > All Programs > TightVNC > TightVNC Viewer).

1. Enter the IP address or valid DNS name of the thin client that is to be shadowed/operated/monitored (you can also set other options using the command buttons).

2. Click OK to open the VNC Authentication dialog box.

3. Enter the Password of the thin client that is to be shadowed (this is the Security Password of the thin client that is to be shadowed - see "VNC Server") and click OK. The thin client that is to be shadowed/operated/monitored will be displayed for the administrator in a separate window on the remote machine. Use the mouse and keyboard on the remote machine to operate the thin client just as you would if you were operating it locally.

XTerm

XTerm is the standard terminal emulator for the X Window System. Use the terminal emulator window for X (click XTerm) to access a text terminal and all its applications such as command line interfaces (CLI) and text user interface applications. You can click the Window menu (upper left icon) to open and use the XTerm menu. You can type help and press Enter to display a verbose message describing XTerm options.

A Central Configuration: Automating Updates and Configurations

This appendix describes how to set up your environment to provide your thin clients running Wyse Enhanced SLE with automatic updates and configurations in three simple steps.

It includes:

• "How INI files Are Employed"

• "How to Set Up Automatic Configurations and Updates"

TIP: Dell thin clients do not require device management software. They are configured to obtain their IP address, as well as the location of firmware and configuration instructions, from a DHCP server. However, you can use WDM or the Wyse USB Firmware Tool for a more hands-on management of client configurations and updates. For information about configuring thin clients to communicate with a WDM server, see "WDM (Agent Configuration)" and related INI parameters in Reference Guide: Wyse ®

Enhanced SUSE Linux Enterprise SP2 INI Files.

IMPORTANT: If you have cloud clients running on different platforms (for example different classes—Z class, R class and so on) in the same network, see "Mixed Environment Imaging (An Enhanced Method of Upgrading)."

68 Appendix A

How INI files Are Employed

INI files (created and maintained by the network administrator) determine how the thin client is configured and updated. The thin client accesses INI files from the server during the initialization process. Typically, INI files are accessed through FTP, HTTP, and HTTPS; if no protocol is specified, the default is anonymous FTP.

IMPORTANT: The INI file processing hierarchy is as follows:

• Scenario 1 - MAC.ini exists. The MAC.ini file is processed and if the Include=WLX.ini statement is included, then the WLX.ini file is processed.

• Scenario 2 - MAC.ini exists and {username}.ini exists. The MAC.ini file is processed and if the Include=WLX.ini statement is included, then the WLX.ini file is processed. Once the credentials are provided, the {username}.ini file is processed.

• Scenario 3 - WLX.ini exists. The WLX.ini file is processed.

• Scenario 4 - WLX.ini exists and {username}.ini exists. The WLX.ini file processed. Once the credentials are provided, the {username}.ini file is processed.

• Scenario 5 - No ini files exist. Local configuration is applied.

INI files are employed as follows:

• wlx.ini - This is the global INI file. One wlx.ini file is available to all users. It contains global parameters for all thin clients accessing the server. If the operating system cannot find wlx.ini, it defaults to wnos.ini.

• {username}.ini - This file is unique to each user. The {username}.ini file contains the connection profile for each user. Parameters in the user profile generally supersede the identically named global parameters.

• $MAC.ini - This file can be used for device-specific configuration. If the thin client locates this INI file (it is stored in the same directory as wlx.ini), wlx.ini is not accessed, unless you use the include=wlx.ini parameter. Note also that the placement of the include=wlx.ini parameter within the $MAC.ini file will dictate which value will take priority for a same specific parameter that is contained in both the wlx.ini file and the $MAC.ini file but is defined differently (different values for the same parameter). For example, if the wlx.ini file has parameterA=valueB, and the $MAC.ini file has the same parameterA=valueC, then:- If the include=wlx.ini parameter is included in the $MAC.ini file before the parameterA=valueC statement, then the wlx.ini parameterA=valueB is discarded and parameterA=valueC (from the $MAC.ini file) is the final value used.- If the include=wlx.ini parameter is included in the $MAC.ini file after the parameterA=valueC statement, then the $MAC.ini parameterA=valueC is discarded and parameterA=valueB (from the wlx.ini file) is the final value used.

When a thin client is initialized, it accesses the global wlx.ini file. When a user logs in, the thin client accesses the user’s unique {username}.ini file. For detailed information on constructing and using Wyse Enhanced SLE INI files, see Reference Guide: Wyse ®

Enhanced SUSE Linux Enterprise SP2 INI Files.

TIP: If both PNLite and a user profile are being used, the username must be defined in the Windows domain to be used, and the password must be the same for the domain and the profile.

Central Configuration: Automating Updates and Configurations 69

How to Set Up Automatic Configurations and Updates

For a Dell thin client running Wyse Enhanced SLE to successfully access INI files and update itself from a server, you must set up the server with the correct folder structure (where the INI files and other update files are located), direct the thin client to the server, and then reboot or start the thin client.

After DHCP and servers are configured and available, the thin client checks (at each boot up) to see whether or not any updates are available on a predefined server (DCHP Option #161specifies the server URL, DCHP Option #162 specifies the root path to the server). If updates are available, the updates are automatically installed.

Step 1: Prepare the Root Directory and Folder Structure on the Server

Set up the following folder structure on your server under the C:/inetpub/ftproot folder (for FTP) or C:/inetpub/wwwroot folder (for HTTP or HTTPS) and place your INI files and other necessary files inside the structure as noted (this list describes the folder structure, starting with the root directory).

/wyse/ The root directory. It stores the wlx folder and the addons folder.It also stores the following files, which are used for imaging and updating devices:

• Latest-image.raw

• Latest-image.raw.info

/wyse/wlx The main INI configuration folder. It stores the following:

• wlx.ini file and $MAC.ini file

• bitmap folder

• certs folder

• ini folder

/wyse/wlx/bitmap The folder where you can place custom images you plan to use.

/wyse/wlx/certs The folder where you can place the CA certificates that can be imported to a thin client. Note: Use the Certs and ImportCerts INI parameters in the wlx.ini file to import the certificates to thin clients.

/wyse/wlx/ini The folder where you can place the {username}.ini files.

/wyse/addons The folder where you can place the add-ons you want to use. It also stores the directory file and the *.rpm packages available to be installed on the thin client. The directory file should list all available add-ons. The directory file is required in the addons folder to guarantee that add-ons are properly located.NOTE: If you want to do an update with the Preserve changes option enabled, ensure that your addons folder includes a copy of your current add-ons. The system may require two reboots to fully update the firmware and add-ons while preserving local changes.

70 Appendix A

The following figure shows how to set up the folder structure on your file server and where to place INI files and other necessary files inside the structure.

Be sure to create/activate the two required MIME Types (.ini and .) under IIS (on a per site basis) to enable downloading. Also be sure your Web server can identify the file types used by Dell thin clients.

To create/activate the .ini MIME Type:

1. On your IIS server, use the File Types menu to add a New Type.

2. In the File Type dialog box, enter the Associated extension .ini and Content type (MIME) text/plain.

3. Click OK to apply the settings.

To create/activate the . MIME Type:

1. On your IIS server, use the File Types menu to add a New Type.

2. In the File Type dialog box, enter the Associated extension . and Content type (MIME) text/plain.

3. Click OK to apply the settings.

For detailed instructions on adding the .ini and . MIME Types, see Knowledge Base Solution #21581 (go to the Knowledge Base at http://www.wyse.com/kb and search for 21581).

http://www.wyse.com/kb




Step 2: Direct the Thin Client to the Server

After you set up the folder structure and populate it with the correct files, you must then direct the thin client to the location of the server by one of the following ways:

• DHCP (see "Using DHCP")

• Manual direction (see "Manually Configuring the Server Location")

IMPORTANT: Using DHCP is strongly recommended.

Using DHCP

When using DHCP to direct the thin client to the location of the server (recommended), information about the server and root directory is obtained from the following DHCP options:

• 161 - The server.

• 162 - Root path to the server (ftp/http/https).

· If no root path is defined, /wyse is assumed.

· If a root path is defined, the additional path will be appended to the URL supplied by option 161.

• 184 - (Optional) Server username (to server specified in option 161).

• 185 - (Optional) Server password (to server specified in option 161).

IMPORTANT: Check-in for firmware updates is done early in the boot process. For that reason, changes in DHCP information may not be propagated to a unit until a full boot is completed. However, you can avoid this by forcing a renewing of the DHCP lease, which makes sure that the unit has the latest file-server location before the next firmware check. Simply, right-click the Network Manager icon, click Enable Networking to disable it, right-click the Wireless Manager icon, and then click Enable Networking to enable it again (the DHCP lease is renewed).For general instructions on adding DHCP Options #161 and #162, see Knowledge Base Solution #16132 (go to the Knowledge Base athttp://www.wyse.com/kb and search for 16132).

Use the guidelines shown in Table 2 when creating and adding the DHCP options you need.

Table 2 DHCP Option Tags

Option Description Notes

1 Client identifier Always sent.

2 Time Offset Optional.

3 Router Optional but recommended. It is not required unless the thin client must interact with servers on a different subnet.

6 Domain Name Server(DNS)

Optional but recommended.

12 Host Name/Terminal Name

Optional string. The host name or terminal name to be set.

15 Domain Name Optional but recommended. See Option 6.

28 Broadcast Address Optional.

44 WINS servers IP Address

Optional.




72 Appendix A

51 Lease Time Optional but recommended.

52 Option Overload Optional.

53 DHCP Message Type Recommended.

54 DHCP Server IP Address

Recommended.

55 Parameter Request List

Sent by appliance.

57 Maximum DHCP Message Size

Optional (always sent by thin client).

58 T1 (renew) Time Optional but recommended.

59 T2 (rebind) Time Optional but recommended.

61 Client identifier Always sent.

161 Server (ftp/http/https) Optional string. If this is an IP address or resolvable hostname, the protocol is assumed to be FTP; however, it may be the leading portion of a URL that specifies another protocol. If using the URL form, it should not include a trailing slash (for example, http://server.example.com or ftp://192.168.0.1).

162 Root path to the server (ftp/http/https)

Optional string. The relative directory starting from the root directory must be given. For example, on an FTP server, the full directory may be C:/Inetpub/ftproot/wyse, where wyse is the directory that contains the firmware. In this example, the correct string value for this DHCP option is /wyse. On a Linux server, an FTP user-based directory might be /home/test/wyse. In this example, if the FTP user is test, then the FTP root path is /wyse and not the full path (/home/test/wyse).This value should use URL path notation (start with a forward slash, /, and use a forward slash as folder separators).

181 Wyse PN Server Optional string. IP address or FQDN of the PNLite server.

182 Wyse Admin List Optional string. DHCP equivalent of the DomainList ini file parameter.

184 Server Username Optional string. Username to use when authenticating to the server specified in Option 161.

185 Server Password Optional string. Password to use when authenticating to the server specified in Option 161.

Manually Configuring the Server Location

To manually configure the file server location (not recommended), open the INI and Upgrade Settings dialog box (Computer > Control Panel > INI Settings), clear the Get INI and Upgrade server details via DHCP check box, and then enter the URL (for HTTP or HTTPS; FTP URL is allowed for FTP) for the INI server in the INI Server URL text box. For more information, see "INI (and Upgrade) Settings."

TIP: You can also click Image Upgrade Settings to configure the INI and upgrade network settings as described in "Configuring the Image Upgrade Options."

Step 3: Reboot the Thin Client

After you reboot (or start the thin client), the thin client will look in the defined root path for the latest available image and update if necessary. Additionally, it will check the directory file in the addons folder to see if any updates for installed add-ons are defined. Add-ons that exist in the addons folder but are not listed in the directory file, will be ignored during update check-in.

186 WDM IP Address Optional binary IP address of the WDM server. This option can specify up to one WDM server.

191 XenDesktop DDC URL Optional string. See also "Desktop Appliance."

194 WDM FQDN Optional FQDN of the WDM server. This option can specify up to one WDM server.

This appendix details the improved method of upgrading a mixed environment of cloud clients using the mixed_env_upgrade addon (installed on the cloud client) and the Upgrade.Image_RootPath=/…./$PLATFORM/…. key (contained in the ini file). This new method improves the upgrade process so that there is control over limiting the upgrade to particular platforms of cloud clients in the network.

When cloud clients running on different platforms (for example different classes—Z class, R class and so on) are in the same network and are upgraded using a single upgrade image on the server, the cloud clients that are incompatible with the current image will not upgrade properly. The problem occurs because all the cloud clients are looking in the same path on the server for the upgrade image. The new method of upgrading addresses this issue and provides a way of upgrading only cloud clients in the network for which the upgrade is intended. The mixed_env_upgrade addon will parse the ini setting and set the root path on the cloud client. This root path will be relative to the type of cloud client platform, and therefore after setting the root path, the cloud clients will be looking in different locations on the server for the upgrade image intended for their specific platform.

NOTE: The new addon code will be added under the wyse/addons directory. The addon is an ini parser. If the $PLATFORM is found in the Upgrade.Image_RootPath then the parser will replace the $PLATFORM with the cloud clients platform type and set the root path to the value of Upgrade.Image_RootPath. For example if the platform type is Z50D, then the RootPath will be set to /…./Z50D/…. The root path setting will be saved in the temporary registry. Platform types include C50LE, D50D, R50L, R50LE, X50M, Z50D, and Z50S.Example:For ini setting:Upgrade.Image_RootPath=/xyz/$PLATFORM/dir1/dir2/

The Z50D cloud client will obtain the image from:ftp://xx.xx.xx.xx/xyz/Z50D/dir1/dir2/

The Z50S cloud client will obtain the image from:ftp://xx.xx.xx.xx/xyz/Z50S/dir1/dir2/

IMPORTANT: The root path is case sensitive.

Resetting the Root Path: The RootPath on the cloud client can be reset back to default, by setting any of the following ini settings:

1. FirmWareRootPath ini settings

2. Upgrade.Image_RootPath without $PLATFORM

Method 1 will work in all cases. Method 2 can also be used if the new addon to parse Upgrade.Image_RootPath is installed on the cloud client. By resetting back the root path to default, any image or addons common to all the platforms can be installed.

Support Details

The following is supported:

• INI upgrades using FTP, HTTP, or HTTPS on C (SP1 only), D (SP2 only), R (SP1 only), X (SP1 and SP2), and Z (SP1 and SP2) cloud client platforms in the same network.

• Image, Image plus addons, and addons upgrades

The following is NOT supported:

• upgrades on the T and PC Extender cloud client platforms

• upgrades using WDM

For example, the following is the directory structure of the image and addons under the root path:

The Z50D cloud client will upgrade from:

…./Z50D/.…/ latest-image.raw latest-image.raw /addons/directory *.rpm

The Z50S will upgrade from:

…./Z50S/.…/ latest-image.raw latest-image.raw /addons/directory *.rpm

The file directory lists the names of the all the addons which are to be updated. NOTE: No image should be put in the wyse root directory when using this method.

Supported Use Cases

• Old SP2 Image -> old SP2 Image (before 11.2.27.01)Install new addon, set ini settings, and then place the image in the root path.

• Old SP2 Image -> latest SP2 Image (11.2.27.01 onwards with info file details)Install new addon, set ini settings, and then place the image in the root path.

• Old SP1 Image -> old SP2 Image (before 11.2.27.01)Install new addon, set ini settings, and then place the image in the root path.

• Old SP1 Image -> latest SP2 Image (11.2.27.01 onwards with info file details)Install new addon, set ini settings, and then place the image in the root path.

• Latest SP2 Image (11.2.27.01) -> latest next SP2 Image (11.2.27.01 onwards with info file details)Install new addon, set ini settings, and then place the image in the root path.The SUPPORTED_PLATFORM in the info file should specify the platform type of the cloud client, otherwise the image will not be updated.

• Latest SP2 Image(11.2.27.01) -> old SP2 Image (before 11.2.27.01 onwards with info file details)Install new addon, set ini settings, and then place the image in the root path.Manually add platform type to the info file as follows.SUPPORTED_PLATFORMS=D50,X50M,Z50D

• Old SP1 Image -> old/new SP1 Image Install new addon, set ini settings, and then place the image in the root path.

78 Appendix B

Directories on the Server

Administrator must create the following directories on the FTP server. For example:

ftp or http or https://ipaddress/

…./Z50D/.…/latest-image.raw latest-image.raw.info /addons/directory *.rpm …./R50/…/latest-image.rawlatest-image.raw.info /addons/directory *.rpm

.…/D50/.…/latest-image.raw latest-image.raw.info /addons/directory *.rpm…./X50M/.…/latest-image.raw latest-image.raw.info /addons/directory *.rpm

IMPORTANT: …. represents any level of directories. For example the above path can be set by the administrator as ftp://server_ip_address/xyz/Z50D/abc/qrt/.

The image for the Z50D will be in the directory ftp://server_ip_address/.../Z50D/.../ and for the X50m the image will be in the directory ftp://server_ip_address/.../X50M/.../.

In the case of cloud clients running SP1, the SP1 image will upgrade to the latest version after reboot and in the case of cloud clients running the latest SP2 image, the Delayed Update will download the image upon network reset or reboot and prompt the user for the upgrade.
