Hacking Wake PC via Wii via WOL

[WiiCrazy]

LibOGC (or rather, IOS) definitely has some quirks when it comes to UDP and broadcast mode... I did some quick changes to that source code and it seems to work for me, if anyone with a compiler wants to try it out here is the source: http://pastie.org/936868
Obviously change the IP and MAC strings to match the machine you're trying to wake.

Hmm, I'll give it a try... I had tried different socket types but never tried supressing the error from setsockopt. I guess finally @Op has a solution

Doesn't work for me

What OS is on the machine you are managing to wake ?

 

[tueidj]

Windows XP, wired connection (duh), in the device properties for my network card the wakeup capabilities are set to MagicPacket+PatternMatch.

Edit: Also under power management, ticked "Allow this device to bring the computer out of standby."

The only difference is then, that I'm using Windows 7
I'll give it a go with XP ...

/EDIT: Yup - works with XP thanks

Hmm, It's a little too eager with XP. The server wakes if any other PC is on, regardless of whether I send a magic packet or not

I'll have to see if I can't get it working with Win7. Getting closer though

It seems that what is waking the PC is just the fact that something is being broadcast to all network cards (and that particular one isn't so fussy about what it wakes to). If you set the card to wake only to a magic packet it will not wake. If you set it to wake to pattern match (or anything including pattern match) it does wake, but not to any particular MAC address - any MAC address will do, it still wakes. Also if any other PC is turned on in the Network it prevents the server from sleeping (even if it is not trying to connect to it).

Good news though for those with just 1 PC and a Wii - That'll do nicely

Sounds like the contents of the packet that the wii sends isn't quite what it should be (doesn't match the definition of a "magic packet"). I just followed the original source code, so I'm afraid I can't help much. But at least broadcast mode is working.

It can't be that far off, and will suit the many that don't have a house full of PCs on the network

 

[tueidj]

It might just be that the packet should be sent to the broadcast address (INADDR_BROADCAST) rather than the ip of the target. Make sense since the latter would require an ARP lookup which is a bit difficult when the target is off and unable to respond.

Not really up on wii programming, so no idea how to substitute that info.

Sounds logical though - I don't believe that the magic packet requires IP address at all. I think some use the IP address initially to get to the MAC address, but it is not used when sending magic packet (for the reason you mention - when the machine is 'off' it doesn't have an IP address)

Don't quote me on any of that - just ramblings of the limited info I have picked up from here and there

 

[tueidj]

Instead of

host2addr(IP,&sin.sin_addr,&sin.sin_family);

it would be something like

sin.sin_addr.s_addr = htonl(INADDR_BROADCAST);

Wouldn't 255.255.255.255 work for most home networks?

@tueidj

Well done Champ!

Lan card set to wake on magic packet only - Wii wakes it every time

 

[XFlak]

so is this code only useful if included in an app that has SMB support? Is this something that WiiMC or MPlayer_CE could incorporate?

 

[tueidj]

I guess they could, if pastie.org wasn't down and the code was accessible. But somehow the app would need to know the MAC address of the machine to wake.

 

[XFlak]

I imagine that could be added as an optional SMB config setting

I think this would be a great addition to all apps that support SMB (how annoying is it to run upstairs to shake your mouse just so u can watch a movie or load a rom)

SMB share or an FTP server on your LAN (even WiiXplorer would benefit).
Now this code exists, it is would not only be useful with these apps - but an essential requirement.
Knowing that you are going to connect to a remote PC on your lan why wouldn't you send a magic packet to wake it ?
If the machine does not support WOL or is already awake - no harm done.

I have already posted the suggestion on the WiiMC forum here (The thread has been removed for some reason)

Since I did, the only reply has been my own, in which I stated that the working code already exists and put a link to this thread

In an application that this would enhance, you would normally have a means to add the address of the SMB share or FTP server settings so an extra field to add the MAC address for the machine should be no problem. If no MAC address is stated - don't send the magic packet.

It might encourage those developing the likes of WiiMC to include this code, if a few more added their support for this feature to be added

 

[tueidj]

They would probably be even more likely to accept it if a patch was submitted. Developers love it when people make their lives easier.

Once I can coax DevkitPro into compiling the WiiMC source (so I can test it), I'll see if I can make a patch for it - This definitely should be included

That's gonna take some time I see - WiiMC is a w@nker to compile

 

[Screemer]

finally! after over a year of lifting my lazy ass of the couch to turn on my pc, everytime i wanted to watch a movie, that torture is over and i can keep my ass seated

looking forward for an integration in wiimc.

 

[ClockWorK]

This thread is made of 100% win!

 

[Tristar]

OK so I've got my forwarder waking the server before starting WiiMC

Finally got WiiMC compiled - but, as I've already stated, I know bugger all about Wii programming sooo...

If someone else gets this thing integrated into WiMC for heaven's sake let me know and save me some grief

If not, I'll report back if and when I can figure it out
