Woller

ABOUT

Woller is a program I made out of curiosity to QT and me being lazy walking to my MythTV box to power it up. WOL (Wake On LAN [1]) is a feature that allows computers to be powered on by sending them a network package, instead of pushing a power button. So Woller is a "remote power button" for computers.

During the years I've been using WOL (Wake On LAN) feature of computers to wake them up when I need them. But this time I wanted a GUI button to press instead of command line application like the ones I've previously used. I chose QT due just the heck of checking out new framework, and since it can be easily adapted to any Linux like (Meego) internet tablets, Mac, Symbian or even Windows. Anything which runs QT.

Since I was aiming for a desktop widget, I preferred simplicity. I wanted only minimalistic UI, thus Woller only has a list and button. At least for now.

If anyone else finds use for it, feel free to modify it and please send me back any enhancements you may create. Also fixes are welcome.

The code is available at sf.net [2] under GPL license [3].

THEORY

WOL is a network device feature, where network device listens to network for magic packets. When such packet arrives, it wakes up the device it's connected to (host). Usually the network device is PC's or laptops network card, and the device to be woken up is the PC or laptop.

To create such a magic packet, one needs to know the MAC address of the network device. Woller then creates the magic packet using the given MAC address. The network device catches the packet, and wakes up the host.

USAGE

Find your hosts MAC address.

This depends on your operating system. In unixes (linux, mac) it is found by issuing command "ifconfig" on command line. It might be also shown in hosts BIOS settings. Google for "find MAC address".

Make sure WOL is enabled in target host

Go to your hosts BIOS and look for setting "Wake on network", "Wake on LAN" or similar entry in bios and enable it.

Configure Woller

1. Start Woller,
2. and go to configure dialog by selecting "Configure targets" from the drop down menu.
3. That brings you to host list,
   1. where you press "Add" button.
      1. In the dialog that opens, give target host name,
      2. and the MAC address (e.g. format "00:11:22:aa:bb:cc",
      3. and optionally ip network address. The network address is optional.
4. Save changes.

Wake it up!

Wake up the configured target by selecting it from the menu, and press the button next to it. Check that your host starts up.
