Wyse device agent

The Wyse Device Agent (WDA) on the ThinLinux device supports only the features of Cloud Client Manager (CCM) device management solution. Wyse Device Agent is for configuring the CCM (Cloud Client Manager) client settings and registering a ThinLinux device into CCM and it is available only for admin user.
Figure 1. Wyse Device Agent (CCM)
If the device is not registered to a CCM server, the Wyse Device Agent screen shows the registration status as Not Registered.
  1. In the CCM Server input box, enter the URL of CCM server you want to connect to.
  2. In the MQTT Server input box, enter the IP address or hostname of Message Queue Telemetry Transport (MQTT) server.
  3. In the Group Token input boxes, enter your group registration key to manage your ThinLinux device. This is a unique key for registering your thin client device. Thin clients can be directly registered to Groups directly and must have a Group Registration Key enabled to perform this action.
  4. Do one of the following options:
    • Click Register to register your thin client on CCM server. When your thin client is successfully registered, the status is shown as Registered with green color icon next to the Registration Status label, and caption of Register button changes to Unregister.
    • Click Unregister, if you want to remove your thin client from the CCM management system. If Unregister fails, a dialog box for Force Unregister confirmation is displayed. Click Yes to forcefully unregister your device which is managed by CCM. When you perform Register or Unregister or Force Unregister from Agent screen, the applet should not be closed until Registration Status. After successful registration, you can access the CCM management server screen where you can view and manage Device Asset Details, Real-Time commands, and Troubleshooting information of your registered thin client.
    Directing the Thin Client to CCM Server:
    • To direct your thin client to CCM server, you must provide CCM/MQTT server details and Group registration Key. These details is discovered by Wyse Device Agent using any of the following ways:
      • DHCP Scope options
      • Using INI parameter
      • Using the Wyse Device Agent screen

    • Directing the thin client to CCM Server using DHCP Scope options. The CCM/MQTT server details and Group Registration Key that are required for CCM registration can be obtained by querying the DHCP server with following option tags:

      • 199 – Scope option for Group Token (type = String, value = CCM-group-key).
      • 165 – Scope option for CCM server.
      • 166 – Scope option for MQTT server.

    • Directing the thin client to CCM Server using INI parameters, INI syntax for CCM configuration:

      • CCMEnable={yes,no} CCMServer=<CCM Server URL> GroupRegistrationKey=<tenant code-group code> MQTTServer=<MQTT server>[:<MQTT port>]
      • NOTE:
      When INI discovery method is used for registering the device, if you want to unregister the device, you must delete the INI parameters and restart the device first and then unregister the device. Else you have to perform the unregister process twice. For more information, see ThinLinux INI Guide .
