WOL - Wake on Lan

Use iNet's Wake on LAN tool to wake up devices in your local network or via internet. You can set Macintosh computer to sleep or shutdown and send ssh commands.

Users of the Lion operating system and newer should be aware, that on Lion the screen does not light up if you perform a wol, see here.

To display the iNet Wake on Lan tool:

Click on the WOL tool icon at the left side of the iNet window.

To see the WOL status of a device:

The current WOL status of a device is indicated by the bulb below the icon display. Three states are possible:

iNet is currently checking if the device is online.
The device is online.
The device status could not be detected.

To wake, sleep or shutdown a device:

Choose a device from the device list and click on the appropriate button:

The 'Sleep', 'Shutdown' and 'Connect via' buttons are visible only if these tasks can be performed due to the setup of the device. With the 'connect via' switch you can decide if you want to connect locally or via internet.

To send a command to a device (Macintosh only):

You can send ssh commands to a Macintosh device. This works locally as well as via internet. Choose a device from the device list and click on the 'send command' button at the top right:

You can send any command the device can perform, e. g. let the Macintosh say a message or execute an applescript.

To add a device to the Favorites list:

In the Favorites section you can permanently store devices for WOL or for sending ssh commands, either by moving them from the Last Scan section or manually adding via the

button. To remove an item from the list click mark it and use the

button.

Click and keep the mouse button down while moving a device item from the Last Scan section to the Favorites section

All items in the Favorites list can have their own names and icons that are independent from the Last Scan section. To edit click on the Settings button and change the name, to change the icon click on the icon of the device and choose one from the table:

Prerequisites for wake on lan:

To use wake on lan in a network there are some prerequisites to follow:

1. The device you want to wake must be reachable from iNet (connected to the same network).

2. The device to wake must be sleeping (Macintosh) or shut down with a power supplied ethernet card (most Windows devices).

3. The device must be configured correctly to react on the sent wol package. On Maintosh activate "Wake for network access" (if connected by ethernet cable) or "Wake for Wi-Fi network access" (if connected by wifi) in System Preferences -> Energy Saver. A Mac laptop must be connected to a power supply, otherwise the network card will not be powered and cannot receive the wol package.

To set up local wake on lan:

Local wake on lan means that the device you want to wake is within your local network. You need to set the MAC address, the local IP address and the subnet mask. These information is discovered automatically if you perform a network scan with the iNet scan tool while the device is running, so you usually do not need to enter any information yourself.

If you want to set up a favorite manually please use the and the buttons and enter all data by hand. This way you can also enter a device that is currently not running or is in another network (another IP address like xxx.dyndns.com or xxx.yourcompany.com), see below.

Please control that the device you want to wake is wol-capable and is set up correctly. E. g. most laptops can be woken up via lan only if they are connected to a power supply.

To set up wake on lan via internet (remote WOL):

Internet wake on lan means that the device you want to wake is connected to a network outside of your local one. To set up this correctly the foliation preconditions have to be met:

You must have the address where the device is reachable via internet. If you do not have an own reachable (and fixed) address you have to obtain one. There are several ways to get one (even at no cost), e.g. at http://www.dyndns.org.
The router that has to route the wol command has to be capable of forwarding 'magic packets' (most routers can do this)
You have to setup an UDP-port forwarding in the router leading to the device IP address and know the port that is forwarded to the device you want to wake up. Some infos on how to set up a routers portforwarding you can find at http://portforward.com/
The device to wake has to be capable of WOL and must be set up correctly (BIOS, energy saving settings, ...)

The WOL port number you enter here has to be the same as the port number that is entered in the port forwarding of the router the device is connected to. To enter the ssh port is necessary only if you want to use the sleep/shutdown feature or the ssh commands (currently for Macintosh devices implemented only).

To set up for sleep/shutdown (Macintosh only):

You can set a Macintosh device to sleep or shut down remotely. This works locally and - if all preconditions are met - via internet.

Username and password are the same you use to login to the Mac you want to put to sleep. The ssh port you enter here has to be the same as the port number that is entered in the port forwarding of the router the device is connected to.
