You have the possibility to wake up thin clients even if they live in a different network which does not allow broadcast packets from the WAN. The trick is to set up one or more thin clients as Wake-on-LAN proxy. A thin client acting as Wake-on-LAN proxy will never fall asleep itself, as its job is to listen to a special wake-up call from the UMS. This wake-up call tells the Wake-on-LAN proxy to send magic packets to all thin clients or a selection of thin clients in its network. To support this functionality, the Wake-on-LAN proxy thin client must have IGEL Linux version 5.09.100 or higher.
You can define a dedicated Wake-on-LAN proxy, or, alternatively, set the UMS to determine a Wake-on-LAN proxy automatically. However, the latter option cannot guarantee that a Wake-on-LAN proxy can be defined, as this depends on an appropriate device being online in the relevant subnet.
For detailed information, see the Wake-on-LAN chapter in the manual.
To configure a Wake-on-LAN proxy:
- Go to UMS Administration > Global Configuration > Wake On LAN.
- Under Send the "magic packet to ...", choose the adress(es) to which the wake-up call shall be sent.
- Activate Wake On LAN Proxies.
- In the area below Wake On LAN Proxies, click on
- Highlight the desired thin client in the left-hand column.
- Click on
to select the thin client.
Click on OK.
The thin client will now function as a Wake-on-LAN proxy.A thin client that is configured as a Wake-on-LAN proxy can no longer be put on standby or shut down. This restriction applies as soon as the thin client receives the settings from the UMS.
