Problem socket connection in Unix

[JeroenToast]

I'm moving a site from a Windows machine to the online environment (Unix) both running PHP5. But have a problem to get my data properly posted on the Unix machine.

On the unix machine my Content-Length of the post is 20 bytes less. I have put the 2 POST next to each other and they are the same.

Hereby the code that works fine on the Windows machine


[HTML]$body = 'theData';
$boundary = "---------------------".substr(md5(rand(0,32000)),0,10);
$host = theHost;
$port = "8080";
$path = PathToScript;

$data ='--'.$boundary.'
Content-Disposition: form-data; name="theXML"

'.$body.'
--'.$boundary.'--

';
$thepost = 'POST '.$path.' HTTP/1.0
Content-Type: multipart/form-data; boundary='.$boundary.'
Host: '.$host.':8080
Content-Length: '.strlen($data).'

'.$data;

$res = "";
$fsp = fsockopen($host, $port, $errno, $errstr, 30);
if($fsp) {
fputs($fsp, $thepost);

while(!feof($fsp)) {
$res .= fgets($fsp, 128);
}
fclose($fsp);
return $res;
}
else {
return "Error: " . $errstr;
}[/HTML]

But when I run the code on the unix machine the POST fails

Hereby the actual POST
