Remotely power on a notebook / desktop of IMATH

The idea of this feature is simple, everyone should be able to wake their machine using localinfo. We use the standard 'Wake on Lan' (in short WOL) feature to accomplish this.

The following steps have to be taken:

1. Activate WOL on the Device

2. Log in to localinfo: http://www.math.uzh.ch > LI > Remote Power On (WOL)

   • Check if the device is on the list
3. WOL only works over the yellow tagged network (LAN). WOL over WIFI is not supported.

Activate WOL

BIOS: Linux / Windows

Enter the BIOS Setup at startup of the machine. Look for the an Option like Power on by PCIE Devices, Power On by onboard Lan, On Board LAN boot (rom) and set it to enable. It is usually under Boot or Advanced.

OS: Mac OS X

• Open system preferences -> Energy saving options -> wake for network access (or wake for wifi on most notebooks).

• General: if you leave your office, use sleep instead of Power Off.

Note: Some Mac Mini (10.9) don't support WOL.

OS: Windows

To enable WOL under Windows:

1. Right-click Computer > Properties > Device Manager.

2. Under Network Adapters, double-click the device.
3. Tick all the items under the Power Management tab.

OS: Linux

• Install ethtools sudo apt-get install ethtool

• Run the command (necessary after each boot)

  sudo /sbin/ethtool -s eth0 wol g 

• Auto activation during boot:

  • For Debian / Ubuntu Linux (without network manager) edit /etc/network/interfaces and append the following to eth0:

    auto eth0
    iface eth0 inet static
    address 192.168.1.1
    netmask 255.255.255.0
    gateway 192.168.1.254
            post-up /sbin/ethtool -s eth0 wol g
            post-down /sbin/ethtool -s eth0 wol g

  • For RHEL / SL / Fedora / CentOS Linux, edit /etc/sysconfig/network-scripts/ifcfg-eth0 and add / modify the following line:

    ETHTOOL_OPTS="wol g" 

  • or

    ETHTOOL_OPTS="wol g autoneg off speed 100 duplex full "
