ACentral Configuration: Automating ConfigurationsThis appendix describes how to set up your environment to provide your thin clients running Dell Wyse Enhanced Ubuntu Linux with automatic configurations in three simple steps.

• How INI Files are Employed

• How to Set Up Automatic Configuration

NOTE:

Dell thin clients do not require device management software. They are configured to obtain their IP address, as well as the location of configuration instructions, from a DHCP server. However, you can use WDM for a more hands-on management of your thin clients. For information about configuring your thin clients to communicate with a WDM server, see WDM and related INI parameters in Reference Guide: Dell Wyse Enhanced Ubuntu Linux INI Files.

How INI Files are Employed

INI files created and maintained by the administrator determine how the thin client is configured. 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.

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.

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 Ubuntu Linux INI files, refer to Reference Guide: Dell Wyse Enhanced Ubuntu Linux INI Files.

NOTE: 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.

How to Set Up Automatic Configuration

For a thin client running Dell Wyse Enhanced Ubuntu Linux to successfully access INI files and configure itself from a server, you must set up the server with the correct folder structure, where the INI files and other 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 configuration changes are available on a predefined server DCHP Option #161 specifies the server URL, DCHP Option #162 specifies the root path to the server. If configuration changes are available, the changes are automatically installed.

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 folders.

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

• wlx.ini file or 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 *.deb 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.

92

NOTE: If you want to do an update with the Preserve changes option enabled, ensure that your addons folder includes a copyof your current add-ons. The system may require two rebootsto fully update the add-ons while preserving local changes.

To create/activate the .ini MIME Type:

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

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

• Click OK to apply the settings.

To create/activate the . MIME Type:

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

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

• Click OK to apply the settings.

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:

• Manually Configuring the Server Location

• Using DHCP

NOTE: 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.

93

NOTE:

Check-in for configuration changes 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 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).

DHCP Options

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

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.

28 Broadcast Address Optional.

44 WINS servers IP address Optional.

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

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

94

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 INI files. 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 separators3.

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

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

186 WDM IP Address Optional binary IP address or FQDN of the WDM server. This option can specify up to one Wyse Device Manager server.

Manually Configuring the Server Location

To manually configure the server location (not recommended), open the INI Settings dialog box and 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 Configuring the INI Settings .

95

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 configuration changes if necessary. Additionally, it will check the directory file in the addons folder to see if any changes 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 check-in.
