WOL: Remotely power on a notebook / dekstop 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 > Power On (WOL)

Check if the device is on the list and note that WOL only works over the yellow tagged network.

Activate WOL

Mac OS X

Setup

Open system preferences -> Energy saving options -> wake for network access (or wake for wifi on most notebooks). Use "sleep" instead of Power Off.

BIOS

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

Windows

To enable WOL under Windows:

Right-click Computer, then click Properties > Device Manager.
Under Network Adapters, double-click the device.
Tick all the items under the Power Management tab.

Linux

If you are using RHEL / SL / Fedora / CentOS Linux, edit /etc/sysconfig/network-scripts/ifcfg-eth0 and add / modify the following line:

ETHTOOL_OPTS="wol g"

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

Save and close the file. If you are using Debian / Ubuntu Linux, edit /etc/network/interfaces and append the following to eth0:

   1 auto eth0
   2 iface eth0 inet static
   3 address 192.168.1.1
   4 netmask 255.255.255.0
   5 gateway 192.168.1.254
   6         post-up /sbin/ethtool -s eth0 wol g
   7         post-down /sbin/ethtool -s eth0 wol g

-Open system preferences -> Energy saving options -> wake for network access (or wake for wifi on most notebooks). Done.
Sadly this quick and easy setup also has one negative point - you have to leave the machine in sleep mode to boot it over LAN.

-Most computers support Wake on LAN on a wired network.
The Wake on LAN feature allows you to turn on a computer in SLEEP or HIBERNATE mode via the network.
The HIBERNATE mode usually is present when you shut down your machine and leave it connected to an active powerline. As soon as it doesn't have an external power source anymore, it quits HIBERNATE mode and shuts down completely to save battery.
To enable Wake on LAN (WOL):
 1. On bootup, instructions to access the BIOS will be briefly displayed. Press this button to enter the BIOS. The hot key is commonly either DEL, F12, or F8.
 2. Using your BIOS, modify the boot sequence to make LAN first priority.
 3. In a generic BIOS, boot priority settings can be found in the Boot Menu.
 4. In the BIOS Setup program, set the items Power On by PCIE devices and Power On by Onboard Lan to [Enabled].
