WOL (Wake on LAN) script - start a computer remotly

I am working on an advanced Wake On Lan script for XBMC. So far the WOL function is working and I would like to add the ability to show if a machine is up or off (I figured I would do so by pinging the machine and seeing if I get a response). I would also like to add the ability to remotely shutdown a computer from the XBMC script. Does anyone have a code snippet for pinging an IP, a code snippet for shutting down a remote Windows machine, and a code snippet for sending a HTTP request?

Here is my current setup:

Latest XBMC
FreeNAS (media server running on FreeBSD. Can be shutdown from web interface so I planned on just sending that same web button click from XBMC to shutdown the FreeNAS server)
Windows XP machine with folder share (What packet is sent over the network to remotely shutdown a Windows XP machine?)

My hope is to have a script then when you start it will list all your remote computers/servers and show if they are currently on/off. Then you can select a server and turn it off if it is on or turn it on if it is off.

Thank you in advance for any help provided.

I don't know if its completely necessary, but I know the shutdown on lan script already on xbmcscripts uses a client that you have to run on the computer in order to to tell it to shutdown...Would be great if you could do it without it though

JoJa15,
Did you ever get this working the way you wanted?
I'd be interested in seeing it if you wouldn't mind.

I am trying to get my Xbox to send a WOL to my server when XBMC starts. I understand how to use autoexec.py. The problem lies in trying to find the correct WOL script. I have the tweaked WOL, but it opens a GUI to select the PC to wake. This is great if I have other computers to wake, but I want it to always wake the server and not show a GUI when running at startup. All my searches for the older WOL showed either dead links or the code I lifted from the posts did nothing. Can anyone please help me out?

I had a look and couldn't find it so the code is below (change the MAC). You can wake more than 1 by duplicating the WakeOnLan(MAC) line.

Alternatively you can use Nuka's Plug-in maker (in SVN) to send a WOL packet when the desired share is required.

That is the exact code I tried to lift and use. When I run it nothing happens. If I run the tweaked WOL script it works properly.

I looked for Nuka's Plug-in maker and could not find it. Is it only in the SVN? So I need to find it there? I'd love for it to only send the WOL when the share is requested. That is even better than always waking the server at boot up.

I got the script working now. I changed the port from 9 to 7. I thought I did that before and it didn't work...oh well. It is now. Smile

I tested before I posted, and copied and pasted from the forums just to double check, and it all works fine. Have you tested as just a standalone script?

The repositry is covered in this thread http://forum.xbmc.org/showthread.php?tid=29911

The plug-in created uses a modified version of the script I posted.

Thanks for the info. Look above, I got it working. I'm not sure why it didn't earlier. Maybe a bad copy paste. Thanks again.

Followup,
So now that I got the script working, I ended up just adding:
Code:
<onclick>XBMC.RunScript(Q:\scripts\Wake\wakePVR.py)</onclick>
to the items on the home screen that access content on that computer. This way it only wakes that PC when it needs content from it. So far it works like a champ. The only downside is having to edit the homescreen whenever I update the skin.

Thanks ozNick... that standard WOL python script works great, and will power on my computer from S3 when PME is enabled in the BIOS, just as I wanted.

There is one thing I can't seem to resolve though: booting to and shutting down the system from Windows with the device manager options set to allow booting via ethernet magic packets means WOL works flawlessly every time, but if I don't the WOL will not work. It's not a big deal because Windows is what I use 99% of the time but I'd like it so WOL works regardless of whether it was shut down from Windows, just in case I forget or whatever.

Hi,

I use MySQL which is installed on my Asrock with Windows 7 in living room.
I don't use it all the time, so it automacicallly go to "sleep".

When is in "sleep" mode I can't (not able to connect to MySQL) run xbmc client on other laptop before I turn on Asrock. How I can send "wake on lan" to my Asrock before or during start client on another PC/laptop ?

many thanks for any tips,

regards
