Setup Wake On LAN with TeamViewer?

[aeroencychris]

Hi,

I have a desktop PC at home that I would like to access from my laptop while I'm away at school. TeamViewer is the obvious solution to this, but only works when the computer is online. I found out about Wake On LAN, which can, as it states, wake up your computer from sleep or even complete shutdown (after, say, a power outage) and make it accessible from your other device. I've gotten this to work over a local network, but it's apparently possible over external networks. Could anyone guide me to a place to figure out how to configure my router/Teamviewer for remote use? I couldn't find anything that explained everything I needed.

you'll need to open some sort of port.

I figured, do you know which one?

There's a guide here: http://www.howtogeek.com/192642/how-to-remotely-turn-on-your-pc-over-the-internet/

They mention UDP ports 7 and 9.

 

 

The Port-Forwarding Method

Wake-On-LAN uses UDP. Many utilities use ports 7 or 9, but you can use any port you like for this. You’ll need to forward a UDP port to all IP addresses behind your router — you can’t just forward to a specific IP address. The Wake-on-LAN packet must be forwarded to every device running behind your router, and a device will only wake up if the information in the WoL packet matches it. This is known as a “subnet directed broadcast.”

To do this, you’ll need to forward the port to the “broadcast address,” which will broadcast the packet to all computers on a network. The broadcast address is 192.168.*.255. For example, if your PC has the IP address 192.168.1.123, you’d enter 192.168.1.255 as the broadcast address. If your PC has the IP address 192.168.0.123, you’d enter 192.168.0.255 as the broadcast address.

 

Personally if I was going about something like this, I'd have a computer/IoT device always on indoors, such as a Raspberry Pi. Then, when I open a particular webpage on the device, or send encrypted credentials etc, it would run a python script to send the "magic packet" (The destination computer's mac address) out to every device on the internal network, causing the PC to power on. I wouldn't broadcast my computer's mac address out on the internet, way too risky in my opinion.

I happen to have a Pi, how would I set this up? Also, how would I turn the pi back on if, say, the power goes out?

Without trying to port forward have you tried using hamachi?

The pi automatically turns on and scans itself for corruption after an unexpected power-cut. The results are available in the system log. I found this python script on google: http://code.activestate.com/recipes/358449-wake-on-lan/ Don't forget to change the MAC address to the computer you want to wake.

 

To run the python script when a webpage is accessed, you'll need to install a webserver and PHP first. Don't install MySQL as you won't need it.

Found an excellent guide here: http://www.instructables.com/id/Setup-a-Raspberry-Pi-PHP-web-server/step5/Install-Lighttpd-PHP/

 

After installing the webserver, go to the webserver home directory, and save the python script there. Then create an index.php file. This file will contain code to start the python script.

<?   exec("python PythonScriptNameHere.py"); //python script name here   echo "The script has finished running"; //this doesn't appear until the python script finishes running?>

The desktop computer needs to be connected to ethernet for WOL to work. It isn't possible over WiFi because that is powered off in sleep/shutdown, as well as protocol overhead.

Would a guide like this work?

No, but I could probably open ports if I knew how.

Most certainly.

[aeroencychris]

Awesome, I'm working on it now. Thanks for the help. What's the best distro to use? I kinda blindly chose Raspbian.

That's the best to use on a Pi since it's well supported, and every tutorial for the Pi is pretty much guaranteed to work on it. If you run into any errors while downloading something using apt-get, try apt-get update, since the repository links change often

Thanks so much, you're making my life a lot easier
