Powering on (and off) devices remotely via the web.

With this service, you do not need to leave your device on if you think you may need to use it at night, on weekends, or during an extended absence.

The service is accessible via the URL https://apps.citius.usc.es/wakeonlan/.

A list of the devices you are allowed to power off or on will appear, along with their current status. The devices that will appear are your own device (maximum one device per socket) and servers that have automatic shutdown, can be powered on using this system, and you have been granted access.

Depending on the status of each device, you can power on or off the device:

• Off indicator (gray): The device is off; you can turn it on by pressing the button. There is no way to detect if the device powers on correctly until it boots, so the application will wait one minute before attempting to check the device's status again, and then it will recheck. If the device remains off (gray), it is likely that Wake on LAN is disabled in the BIOS or on the network card.
• On indicator (static blue): The device is on; you can turn it off by pressing the button. Only devices with Ubuntu 18.04 from CITIUS can be turned off using this system. Other devices will receive an error when trying to turn them off. Servers with automatic shutdown cannot be turned off manually, and the button will appear grayed out.
• Working indicator (blue in motion): The device is being powered on or off at the moment, and you cannot do anything. The indicator will be in this state for one and a half minutes after powering on or off the device.

Press the Logout button to log out of the application.

• Support for shutdown on Ubuntu 18.04.

• Recognizes the login from the main page of the center http://citius.usc.es/, so if you are logged in there, it is not necessary to log in again.
• 1.2.3: Directly uses the center's login form if you are not logged in.

• If the device cannot be turned off or on, it does not appear in the list.
• If the device cannot be turned off, the shutdown button does not appear.
• If the device cannot be turned on, the power-on button does not appear.

This may be due to several causes:

• The device is stuck in some boot sequence (BIOS, Grub menu, etc.) and requires manual intervention.
• The device is not connected to the network.
• The device is not correctly configured for Wake on LAN. This can happen the first time you try the tool. Notify the TIC Infrastructure Management Unit at citius.tic@usc.es to take a look at your device's configuration.

The system has no way to check if the device is really turning on, so after sending the power-on signal, it waits a minute and a half before displaying the actual status again. If after that minute and a half the device still hasn't turned on but does later, it is possible that the indicator will return to the off state for a few seconds and, once powered on, will finally show the correct status.

This may be due to the system being stuck in some shutdown sequence and requiring manual intervention.

Some devices cannot be powered off or on, and if they are on or off, the button will be disabled, depending on the actions that are permitted.

Notify the TIC Infrastructure Management Unit at citius.tic@usc.es. Devices are assigned manually, and there may be an error.
