Remotely power on a notebook / desktop of IMATH

Contents

  1. Remotely power on a notebook / desktop of IMATH
  2. Activate WOL
    1. BIOS: Linux / Windows
    2. OS: Mac OS X
    3. OS: Windows
    4. OS: Linux

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.

Note: Some newer Notebooks may only allow Boot On LAN in Sleep Mode to save Energy.

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:

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

  • Under Network Adapters, double-click the device.
  • Switch to the Advanced Tab and set WOL Magic Packet to enabled

  • Tick all the items under the Power Management tab.

  • Use Windowskey + R and type: shell:::{67718415-c450-4f3c-bf8a-b487642dc39b} and turn Simple TCPIP Services on

  • Open UDP Port 9 in the Windows Firewall
    • go to Control Panel\All Control Panel Items\Windows Firewall, click 'Advanced Settings' on the left, and create a new Inbound Rule to open the required port.

  • Restart Windows

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 "
