Dell Wyse ThinOS Version 8.5 Administrator’s Guide

Configuring the proxy settings

The network Proxy tab supports Wyse Management Suite, HDX Flash Redirection, and RealTime Multimedia Engine (RTME).

Supported protocols—HDX FR, WMS and RTME

For HDX FR: HTTP and HTTPS protocols are supported.
- If both HTTP and HTTPS are configured, the HDX FR works with HTTPS proxy.
- User credential pass through is possible with $UN/$PW.
For Wyse Management Suite: HTTP, HTTPS and Socks5 (recommended) protocols are supported.
For RTME: HTTP, and HTTPS protocols are supported.

From the desktop menu, click System Setup, and then click Network Setup.
The Network Setup dialog box is displayed.
Click the Proxy tab, and do the following:
1. Enter the HTTP proxy port number or HTTPS proxy port number, User name and Password in the respective fields. However, credential pass through ($UN/$PW) is not recommended because it starts before user sign on.
  Wyse Management Suite uses both HTTP/HTTPS and MQTT protocols to communicate with the WMS/MQTT server. However, the HTTP proxy cannot redirect TCP packages to the MQTT server which requires a SOCKS5 proxy server. If there is only HTTP server available, then the real-time command that requires MQTT does not work.
  HTTP/HTTPS proxy default port is 808, and SOCKS5 proxy default port is 1080.
2. Select the Use the first proxy server for all protocols check box to allow all the protocols to use the same server in the HTTP Proxy fields. Both HTTP and HTTPS proxy use the same host and port, and SOCKS5 proxy agent uses HTTP host with default Socks5 port (1080).
  If SOCKS5 proxy is configured, then WMS proxy uses the SOCKS5 only. If SOCKS5 is not configured, then WMS proxy searches for alternative protocols, for example, HTTP in the configuration.
3. Specify the supported applications as Wyse Management Suite, FR and RTME separated by a semicolon in the Apply proxy server on field.
Click OK to save the settings.

User scenario

Configure correct proxy server host and port.
Configure the user credentials according to the proxy server settings.
On system restart, the client checks in to the Wyse Management Suite server through SOCKS5 proxy server. MQTT connection is established through SOCKS5 proxy server. Real-time commands work fine through SOCKS5 proxy server.
Connect to the Citrix desktop, configure proxy in internet options of the browser, and then playback HDX FR through the HTTP/HTTPS proxy authentication.
