If my server is online

Is it somehow possible in Metamod pro to check if a server is Online (webserver port 80), and if it is online then show one module, and if it is offline then show an other module.

I will like to show on my hosted Joomla site, if my home server is online or offline. smile

Best regards
Mads

Re: If my server is online

Hi Mads,

yes, technically you can achieve this. There are some PHP code samples on the net for testing if a server is up or not. Most use the cURL library.

The only problem is that there's a timeout problem - most methods of checking will wait (or need to wait) for a few seconds to see if the connection succeeds. If you do this check in MetaMod, it means that the whole page gets held up for a few seconds which will make the page very slow.

Is this going to be acceptable for you?

Cheers,
Stephen

Re: If my server is online

Hi Stephen,

Thanks for your reply smile

I have search a little on google an came across this:
(fsockopen)

Code:

<?php 

function server2($server, $port, $name) { 

 preg_match("/^(http:\/\/)?([^\/]+)/i", "$server", $match); 

 $host = $match[2]; 

 preg_match_all("/\.([^\.\/]+)/",$host, $match); 



 $matches[0][0] = $matches[1][0]; 

 $host = trim($host); 



 $socket = ""; 

 @$socket = fsockopen("$host", $port, $errno, $errstr, 2); 

 if(!$socket) { 

  $socket = print("\n<br /><font color=\"red\">Server is Offline!</font>"); 

 } else { 

  fclose($socket); 

  $socket = print("\n<br /><font color=\"green\">Server is Online</font>"); 

  ?>

<?php

 } 

} 





$server = 'xxx.xxx.xxx.xxx'; 

if($server!=""){ 

server2($server,"21","ftp"); 

server2($server,"22","ssh");  //

server2($server,"23","telnet"); 

server2($server,"25","smtp"); 

server2($server,"80","http"); 

server2($server,"110","pop3"); 

server2($server,"443","https"); 

server2($server,"3306","MySQL"); 

server2($server,"8080","http_proxy"); 

} 

else 

{ 

$a=$_SERVER['xxx.xxx.xxx.xxx']; 

 

} 

?>

Will that also have timeout issues?
Or can I some how use that in MetaMod Pro?

Best regards
Mads

Re: If my server is online

The default timeout for fsockopen is 60 seconds, so you still have to give it a finite number e.g. 1

Try this:

$fp = @fsockopen("www.example.com", 80, $errno, $errstr, 1);// 1 is the timeout
if ($fp) return XXX;
else return YYY;
// replace XXX with module ID to display if site is up
// and YYY with the module to display if the site is down.

You might want to give it a 2 second timeout instead of 1 second, but you could base that on experiments about what happens when the site is actually up. If it's a quick connection, 1 second may be accurate most of the time.

Cheers,
Stephen
