Dell Wyse ThinOS Version 8.6 Administrator’s Guide

Configuring the Wyse Device Agent settings

1. From the desktop menu, click System Setup, and then click Central Configuration.
   The Central Configuration dialog box is displayed.
2. Click WDA > WMS, and use the following guidelines:
   
   By default, the WMS option is selected. Wyse Management Suite service automatically runs after the client boot up.

   If the first discovery, for example, the Wyse Management Suite service is not successful, it seeks for the next priority, for example, WDM service. This continues until a discovery is successful. If all discoveries fail, it is started again automatically after a fixed time—24 hours.

   From ThinOS 8.6_710 onwards, after the initial INI configurations are received from Wyse Management Suite, the options DNSFileServerDiscover, WMSEnable, and DHCPOptionsRemap are disabled if they are not previously defined. These options are enabled after a factory reset or you can use INI parameters to enable them. For more information about using INI parameters, see Dell Wyse ThinOS Version 8.6 INI Reference Guide at www.dell.com/support.

   1. Enable Wyse Management Suite (WMS)—Select the check box to enable the Wyse Management Suite to discover your thin client.
   2. DNS SRV record—Select this check box if you want the thin client to obtain the Wyse Management Suite values through DNS server, and then try to register into the Wyse Management Suite server. By default, the check box is selected. If the check box selection is canceled, the thin client cannot obtain the Wyse Management Suite values through DNS server.

      To create DNS records in DNS server, use the following information:

      # WMS server URL

      DNS Record Type: DNS SRV

      Record Name: _WMS_MGMT._TCP.<Domain>

      Value Returned: WDMNG Server URL

      Example: _WMS_MGMT._TCP.WDADEV.com

      # MQTT Server URL

      DNS Record Type: DNS SRV

      Record Name: _WMS_MQTT._TCP.<Domain>

      Value Returned: WMS Server URL

      Example: _WMS_MQTT._TCP.WDADEV.com

      # Group Token

      DNS Record Type: DNS Text

      Record Name: _WMS_GROUPTOKEN.<Domain>

      Value Returned: Group Token (as String)

      Example: _WMS_GROUPTOKEN .WDADEV.com

      # CA Validation

      DNS Record Type: DNS Text

      Record Name: _WMS_CAVALIDATION.<Domain>

      Value Returned: TRUE or FALSE (as String)

      Example: _WMS_CAVALIDATION.WDADEV.com

   3. Group Registration Key—Enter the Group Registration Key as configured by your Wyse Management Suite administrator for the desired group. To verify the key, click Validate Key..

      To view the specified group token key, click the Show Key button. Verify whether the specified group token key is correct. You can also press the F5 key to display the group token. When you press other keys on the keyboard, the group token is masked automatically.

      NOTE: A Group Registration Key is not required for the private Wyse Management Suite server. You can provide the Wyse Management Suite server details to enable the device to check in to Wyse Management Suite. ThinOS registers to a quarantine tenant in Wyse Management Suite.
   4. Enable WMS Advanced Settings—Select this check box to enter the Wyse Management Suite server, MQTT server details, and to enable the CA validation. By default, the MQTT server option is disabled. The MQTT server value is populated after the ThinOS device is checked in to the Wyse Management Suite.
      NOTE: If you enable the Wyse Management Suite, ensure that you have entered the Group Registration Key and configured the Wyse Management Suite advanced settings.
      The CA validation is required when you import certificates into your Wyse Management Suite server. By default, the CA Validation check box is selected to improve the security when using the Wyse Management Suite cloud. This change affects connections to any of the following servers:

      • *.dellmobilitymanager.com
      • *.cloudclientmanager.com
      • *.wysemanagementsuite.com

      Table 1. CA validationCA validation details

      Wyse Management Suite deployment	CA Validation
      Private cloud	When you deploy Wyse Management Suite on a private cloud, the Enable CA Validation check box is available to configure after you specify the server details in the WMS Server field. By default, the check box is selected.
      Public cloud	When you deploy Wyse Management Suite on a public cloud, the Enable CA Validation check box is selected by default. You cannot disable the Enable CA Validation option.

3. Click OK to save the settings.

When you modify the ThinOS policy of the registered thin client using Wyse Management Suite, a dialog box is displayed prompting you to postpone or restart the thin client. To apply the settings immediately, click Restart Now. If you want to delay this task, click Postpone.
