Wake on LAN
Wake On LAN
is the application if you need to wake up one of your devices. Please be aware that the device to be woken up must be configured for Wake on LAN usage and thus must be listening to Wake on LAN magic packets for being woken up. How to configure your end devices for being woken up is not part of this small tutorial. Please refer to your devices manufactures references. The Wake on LAN applications in principle can be used like the ping or DNS applications. It mainly differs in two things:
- only favorites from the Wake on LAN section can be used
- only the super favorites or facorites can be used you can not enter a destination manually with the keyboard
The destination field from the Ping sections is not editable and serves only as an info screen which displays which devices is actually being selected on is going to be waked up by pressing the wake button.
Favorites Entries:
A Wake on LAN favorite entry has two more entries than an ordinary favorite. A Wake on LAN favorite additionally requires a MAC address and a port.
Please note that when you enter the MAC address you do not need to enter any “:”. A colon is automatically inserted when editing your favorite.
Please note that this is not the case in the applications super WOL favorite MAC address preferences. There you will need to enter the colons “:” separating each byte of the MAC address manually. Please also not that while within the favorites section only valid HEX characters from 0-9 and A-F are accepted this is not the case when entering the super favorite’s MAC address. Before usage the applications checks any MAC address and thus might later criticize the usage of invalid characters in the super favorite MAC address section.
Broadcast Wake On LAN
If you want to wake up a local host which resides in the same network as your mobile device is usually a broadcast Wake on LAN is being used. For this to happen enter 255.255.255.255 as host address.
Example:
- destination Host IP address is 192.168.1.42 of a network 192.168.1.0 /24
- iPhone’s or IPod Touch’s mobile device IP is 192.168.1.111
You would need to configure:
- Name: My Host (or any other name for your favorite entry)
- Host: 255.255.255.255
- MAC: 11:22:33:aa:bb:cc (here the exact MAC address of the host to be woken up needs to be configured)
- Port: 9 (or any other port but 9 is usually being used since it's the discard port)
If the device to be woken up resides into a different routed network from your on device you either use the end devices IP address as host address or the broadcast address of the destination network. (This eliminates the problem that might occur when using the exact IP address where the router in front of the end devices might not know the MAC address in his ARP cache anymore thus not being able to deliver the Magic Packet to the end device). This usually the Network Broadcast Example should be the prefered solution.
Example:
- Destination Host IP address is 192.168.1.42 of a network 192.168.1.0 /24
- iPhone’s or IPod Touch’s mobile device IP is 172.16.1.42
You would need to configure:
- Name: My Host (or any other name)
- Host: 192.168.1.42
- MAC: 11:22:33:aa:bb:cc (here the exact MAC address of the host to be woken up needs to be configured)
- Port: 9
Or as Network Broadcast example
You would need to configure:
- Name: My Host (or any other name)
- Host: 192.168.1.255 (Broadcast address of the network segment)
- MAC: 11:22:33:aa:bb:cc (here the exact MAC address of the host to be woken up needs to be configured)
- Port: 9
