Wake on LAN (WOL)

Powered-off managed Windows and Linux workstations can be woken (switched on) by remote with the Linux command line tool reveil

• staff or guest members of a D-ITET institute or D-BAUG VAW may wake their institute's workstations

• students may wake workstations in student computer rooms

• The tool can only be invoked on the Linux host login.ee.ethz.ch

• login.ee.ethz.ch is accessible from outside the ETH network with an ssh client.
  An ssh client is typically pre-installed on Linux, macOS or Windows with the Windows Subsystem for Linux (WSL) installed.
  As an alternative to WSL, the standalone client putty can be used.

Usage

1. Log in to login.ee.ethz.ch with your ETH credentials:

   ssh <ETH username>@login.ee.ethz.ch 

2. List all hosts you are allowed to wake from sleep:

   reveil -l 

3. Wake the host(s) you want to access:

   reveil <host1> 

⚠ Be responsible and don't wake workstations you don't need to access. The workstations are switched off to save power.

About reveil

Usage information of reveil can be shown by issuing the following command:

ssh <ETH username>@login.ee.ethz.ch reveil -h 

The manual of reveil can be shown with:

ssh <ETH username>@login.ee.ethz.ch man reveil 

Before you switch off your managed workstation

⚠ Not every workstation supports WOL. If you intend to switch off your workstation and want to wake it later, test first if waking works!

• Linux workstations can be switched off by pressing the power button on the chassis once

• Windows workstations have to do a so-called full shutdown by pressing Shift while selecting Shut down in the start menu

If your workstation cannot be woken, send a support request stating the name of your workstation so we can investigate the issue.
