PHP-WoL with Port Check (similar to ping)

[PRThomasUK]

Hi Guys,
I've owned a QNAP TS109-Pro for sometime now, I really should upgrade but it just keeps going and does what I need and has been running 24/7 since I purchased it...

I've been running a rather basic PHP page from my QNAP to Wake on LAN (WoL) my computer from wherever I am. It worked well and always woke up my PC, however it didn't give any feedback other then the WoL packet was sent! I would therefore have to keep trying to connect to my PC until succesfull. I had a look around for another script that used "PING" to check if the PC was on... It seems running "PING" from "PHP" on the QNAP isn't really possible! I nearly gave up but whilst looking around on the Internet I found a bit of PHP that would open a socket connection to a port on a device. Logically if I can create a connection to my PC it must be ON! Eureka....

I'm no expert with PHP or HTML, however after a few hours of coding I managed to put together exactly what I wanted... A single PHP file that would wake up my PC and report back when it was actually on!

The page generates a FRAMESET (Generally frowned upon, but works well with most modern browsers!) The top frame loads once and sends the WoL packet, the bottom frame then keeps reloading until a connection is made out, or the maximum number of tries is reached...

You can download the PHP source from my blog :-

Thank you ! Perfect script. It runs on my qnap119 24hrs a day.

Even on my PopcornHour C200 it works. There it doesn't show the PHP-wol page but it wakes the selected wol-device (Netgear Ultra6 nas) just fine.

Does anybody still have this script? Need something to wake up a computer from my NAS.

I did some searching for this. Looks like Pete Thomas's old site has been pulled down, and his new one never made it past the setup stage.

But Google found a Danish QNAP user who reposted Pete's work:

Setting up the feature of WoL – meaning: Wake on Lan – on a QNAP server, can sometimes be difficult for people.
Several years ago, a guy named Pete Thomas, wrote a nice script for the exact purpose of WoL’ing. I just changed the variables as described here:

1. First of all, enable WoL in the “System Settings” menu tab “Power” and shut down the server.
2. Download the php source for the wake-up script here and rename it from .txt to .php
3. Edit the script so it match your specific system (see further down below).

You need the following info for the server:
A) MAC address
B) LAN IP address
C) WoL port number (for QNAP it is port 7)
D) A Port number for checking if the server is awake (I recommend 8080 on QNAP)
E) A descriptive name for the sleeping server.

Now execute the script from anywhere in the LAN and your server will boot.

Do not change anything else….

Hope this helps.
