wold

Very simple Wake-on-Lan packet handler with custom action execution.

Scratch your own itch

How it was born (by @pauliuszaleckas):

I started coding this small app to make XBMC start on my PC when "Power On" is pressed on Android remote control. It is possible to wake my PC from suspend, but it boots to XFCE and second "Power On" turns on XBMC and disables VGA while enabling HDMI output.

Raspberry Pi usage (by @houtianze):

I have a raspberry pi with raspbian installed. I manually installed XBMC and wish to be able to start XBMC directly (without ssh in and start the XBMC manually) using the Power button in the [Yatse remote control app] (https://play.google.com/store/apps/details?id=org.leetzone.android.yatsewidgetfree) on my Android phone. I googled and found this program, afer modifying it a bit, my wish came true. To achieve this yourself, just follow the Compiling/Installing and Usage instuctions that follow

Compiling/Installing

To compile:

make

To install (usually you will need to be root)

make install

By default wold is installed to /usr/local/bin. If you want to install to more common place like /usr/bin:

make install PREFIX=/usr

Usage

Usage: wold -u user [-g group] [-p port] [-a action] [-f]
        -u username     run action as different user (required)
        -g group / gid  run action as different group / gid
        -p port         port to listen for WOL packet (default: 9)
        -f              stay in foreground
        -a action       application to run on WOL (default: /etc/wol.action)

Linux PC with VGA and HDMI(to TV) example:

Put this line into /etc/rc.local: DISPLAY=:0.0 wold -u xxx -a /home/xxx/XBMC.sh

In XBMC.sh

xrandr --output HDMI-0 --auto --output VGA-0 --off
xbmc
xrandr --output HDMI-0 --off --output VGA-0 --auto

Raspbian example:

To run XBMC (in raspbian), you can just put this line into /etc/rc.local:

DISPLAY=:0.0 /usr/local/bin/wold -u pi -g video -a /usr/bin/xbmc

Restart your raspbian, then you will be able to start the XBMC using Yaste's power button.
