JS server connection check

[ChojiroShintaro]

Right, basically I need to know what little piece of code checks whether a connection is active. I have very little knowledge of JS, and I've googled through a lot of things but I haven't found anything related to this. I would appreciate some help.

What do you mean by "whether a connection is active"?

Also, is this intended to be put on a webpage? If so, better to use PHP and do it serverside.

 

[ChojiroShintaro]

An offline/offline server status. Yes it's meant for a webpage, but I'm not interested in using PhP. All I have is an IP and Port, no fancy things.

 

[username1]

What I meant was use PHP on your webserver to attempt a connection to the game server.

Why PHP? Because it's much easier to do, and not every client is going to have JS enabled.

as far as I know, JS can access only the domain/ip/port it was invoked from, so you can't host your page http://somewhere and check http://elsewhere:100000 is working or not.. PHP is way easier to use

I have the scripts I need for this in PHP, but what exactly do I need to use PHP? I know very little about it you see...

If only you could read...

...and so what if you don't know much PHP? Learn it!

Do you need anything besides PHP? Such as SQL? I don't know much about these things.

 

[ChojiroShintaro]

Edit: Wtf, wierd forum.

 

[username1]

SQL is for databases, unless you need to store some large amount of data I doubt you'll need it.

But learn it anyway, you never know when it'll become useful...

 

[Gashek]

you don't need sql in order to make a script that would check server status


// edit /// p.s. look up my earlier topics, i already asked for such thing

 

[ChojiroShintaro]

Thanks, I'll try and get it running after I've made head or tails of all this stuff these websites say, they're so confusing...

Edit: I'm on the verge of giving up to be honest, this is ridiculous.

 

[Gashek]

btw, there is that php code

<?php 
$IP = array( 
"test1:" => "localhost:80", 
"test2:" => "192.168.0.31:80", 
); 

while(list($ServerName,$Host)=each($IP)) 
{ 
    list($IPAddress,$Port)=explode(":",$Host); 
    if($fp = @fsockopen($IPAddress,$Port,$ERROR_NO,$ERROR_STR,5)) 
    { 
        fclose($fp); 
        echo "$ServerName @$IPAddress:$Port is Online<br>"; 
    } 
    else 
    { 
        echo "$ServerName @$IPAddress:$Port is Offline<br>"; 
    } 
} 
?>

Thanx to [lexx]

You should only ever look at the official PHP site if you want the real accurate information. Everything else should be just a guideline.

To be honest, I just started "really" writing code in PHP several days ago... all you need is the manual, a text editor, and a webserver with PHP (preferably local) to experiment on. Not really hard, considering I've already written most of an account management system for Gunbound.

Thanx to [lexx][/QUOTE]

Which is all in all a very neat script, prolly couldn't have written it better myself, but a lot more complicated then what the topicstarter needs I deem :) All he probably needs is this:

[php] echo fsockopen("ip.adres.here", port, $errno, $errstr, 2) ? 
    "Server is online!" : "Server is offline!"; [/php]

With the values filled in for my webserver this becomes:

[php]echo fsockopen("fragfrog.nl", 80, $errno, $errstr, 2) ?
    "Server is online!" : "Server is offline!";[/php]

If it tends to state a server is offline when really it isn't, increase the last number (the 2) to a bigger value - this is the timeout in seconds, and sometimes a server fails to respond within the time given. Do note that if you increase it a lot people loading your page will also have to wait for that amount of time. Ie, if you set it to be 30 instead of 2 and a server is offline, people will need to wait 30 seconds before the page continues loading. There are ways around this, but not neat or simple ones as far as I know :smile:

Thanks a lot, I'm just trying to find a webserver with PHP now, I'm not good with webservers ya see...

Edit: I can't find what I need on the official site.

AppServNetwork - apache2.2, mysql5, php5, phpmyadmin 2.9 :tongue:

I would not succest Apache 2.2, it is most unstablest apache done, at lleast for windows platform

Instead of Apache 2.2 i would succest apache 1.3 or 2.0...

Apache Friends - Apache 2, MySQL5, PHP 5.2.0 + 4.4.4 + PEAR, Openssl 0.9.8d, phpMyAdmin 2.9.1.1, SQLite 2.8.15, ADODB 4.93, Zend Optimizer 3.0.2, XAMPP Security Check (Get the older version with Apache 2 from sourceforge.)

I've been running it on my windows server for the past 2 months now without a single crash. Can't call that unstable really :smile:
