When I was working with Seal Online Vengence, once I found the port, it was easy to notify clients when a server was down or up.... however using the same system, I am unable to do the same effect with Q2 why is this? Anyone have an idee how to fix this PHP Code here?

You probably need to use UDP, and then send a "quake style echo or connect", then read the data and indicate up if it's a normla response.

Example from fsockopen:

<?php
$fp = fsockopen("udp://127.0.0.1", 13, $errno, $errstr);
if (!$fp) {
echo "ERROR: $errno - $errstr \n";
} else {
fwrite($fp, "\n");
echo fread($fp, 26);
fclose($fp);
}
?>

can it been done with DNS, instead of ip? Since this will be dynamic, and my DNS updates as my Ip does...

NOTE: I trtied udp with my setup, and it lies and says they are up when they are not, up or not... just not the code your doing yet also

Nevermind about the DNS I can use this instead:

<?php
$ips = long2ip("www.aceintergraphs.com");
$sv1 = @fsockopen($ips, (27910), $errno, $errstr, 0.25);

Apparently Q2 responds to PHP differently than most other servers, so I am tryign to find an Alternate methid of server detection, but through PHP if possible...

reaper · « **Reply #5 on:** December 21, 2010, 01:09:15 PM »

Q2 doesn't respond differently to PHP. Q2 uses its own network protocol which is independent of server side scripts or programs.

If you are looking to see if a service is tied to a TCP socket, then maybe fsockopen will work with default parameters. However that's not actually checking that the application is serving up what it should, but that it is listening on a TCP port. Whether the application is still working depends on the state of the application.

Q2 uses a different protocol than TCP, it uses UDP, which is connectionless. Therefore to get a response back, you have to send something that warrants a response from the application.

Below sends a challenge, and gets a challenge response. The fwrite function takes unicode or something, so I just converted "0xF's" which proceed the challenge. The below is actually fine, it gets a challenge response from the server, if you didn't send the proper challenge, or the Q2 server wasn't responding you wouldn't get a challenge response. You could assign the response to a variable and test it, then print HTML.

For the hostname, the hostname is always pasrsed from the URL/URI and resolved. It's better to use the hostname in case the IP changes. The script you have above doesn't send a challenge, actually I don't think it sends anything to the server, but it would need to send a challenge, and then read the response.

fwrite($fp, "ï¿½ï¿½ï¿½ï¿½getchallenge\n");

reaper · « **Reply #8 on:** December 21, 2010, 01:45:56 PM »

you sent the challenge but you didn't test for a challenge-response. you're literally just printing HTML if you can send a packet to the server.

run the sample I posted and see the output of "echo fread", you just need to assign the output to a variable and test it contains a challenge response, which is in the format "challenge longnumber".

Ace · « **Reply #9 on:** December 21, 2010, 01:52:39 PM »

I do without the echo, same problem, it keeps saying server is online when its not, I only want the servers that are online working, its as if its reading my open ports rather than reading the server itself, check for yourself www.aceintergraphs.com

besides I am not wanting the echo, if it prints it will mess up the formatting on my site...

with this, server 1 2 and 12 should be open, not all...

You're just printing HTML if you can send a packet

fread just reads data from the TCP socket, it doesn't make sure it's a response from a quake server

re-read what I posted

this has been pissing me off, its not your fault and I appriciate your help, but it still insists that all servers are online, when only 3 are online.... I spent 2 days trying to resolve this browsing in php..net and still found not other ways to solve it, I might have to get more detailed with this process, which I am dreading to code....

PS yes I added the echo statement

when you view my page, www.aceintergraphs.com is it showing the same results as I am getting, maybe its because I testing this on teh server itself?

The PHP script says the server is online because you are not checking if it's online or not online.

You are sending a packet, and then writing HTML saying the server is online...You need to check that you are getting a good response from the Q2 server application

Here is something that works. You may even want to see if Q2 has a better application level check available, other than verifying in the Q2 network protocol that you get a challenge-response from a challenge

Quote from: php

<?php
$fp = fsockopen("udp://74.54.186.226", 27910, $errno, $errstr);
if (!$fp) {
echo "ERROR: $errno - $errstr \n";
} else {
fwrite($fp, "ÿÿÿÿgetchallenge\n");
$coutput = fread($fp, 26);
$cresponse = "challenge";

if(strstr($coutput,$cresponse)){
echo "print HTML server up";
}

else{
echo "print HTML server down";
}

fclose($fp);
}
?>

[NOTE: reaper already replied while I was typing this, but I'll post anyway... see below about 'ping' vs. 'getchallenge'.]

Hi,

What reaper has said about the logic is correct. Consider where your "if" statements are. That's where the decision is being made about whether to display "online" or "offline".

As currently written it reads like this:

if (always_true){
 fwrite($serv1, "ï¿½ï¿½ï¿½ï¿½getchallenge\n");
 fread($serv1, 26);
 echo ' Fezonia';
 echo '<img src="images/sonline.gif" width="100" height="8" alt="The Fezonia Realm is Online">';
 fclose($serv1);
}else{
 echo ' Fezonia';
 echo '<img src="images/soffline.gif" width="100" height="8" alt="The Fezonia Realm is Offline">';
}

Also, though, you'll want to use "ping" instead of "getchallenge" to query whether a Q2 server is online. It's less work for the server than 'getchallenge'.

Regards,

quadz

Exmples please as well.... on teh variable I mean and how it should be used

The last example I pasted is a working example, but quadz said to use ping, since it's less work on the server.
