Hey zusammen.
Weil ich nach Jahren einen neuen Router bekommen habe, musste ich mein Router-Parsing-Script überarbeiten.
Damit ist es möglich die am Router angemeldeten Geräte samt IP & MAC Adresse abzurufen.
Darüber lässt sich dann z.B. abgleichen ob Personen (bzw. deren SmartPhones) anwesend sind.
Da es bei der weißen Connect Box etwas komplizierter war an die Liste zu kommen, möchte ich das Script / die PHP Klasse mit euch teilen, vielleicht bringts ja jemandem was… 
Spart auf jedenfall Strom / Energie (Wenn das Haus automatisch merkt das keiner mehr da ist und alle vergessenen Lampen ausschaltet / Heizungen runter regelt.)
<?php
class UnitimediaRouter {
/// you can do your setup here, or pass the configs on the go (as done in the example)
var $ip = '';
var $psw = '';
var $debug = false;
var $lastToken = false;

// Second:
// Login with password to get a SID aswell
function login($psw = false){
if ($psw === false){
$psw = $this->psw; // use default settings
}
// Post Data
$post = array(
'token' => $this->lastToken,
'fun' => 15, // function 15 => login
'Username' => 'NULL',
'Password' => $psw
);
// header

// perform request
$result = $this->httpRequest('/xml/setter.xml', $post, $header);
// Update Token (changes every time)

return false;
}
// Valid response?
if ($result['info']['http_code'] != 200 || !$result['body'] ){
return false;
}
// Get Information (SID!) from response body
$responseData = explode(';',$result['body']);
if ($responseData[0] != 'successful'){ // Is either "successful" or "useridwrong" (or something like that)
return false;
}
$this->sid = $responseData[1]; // save SID
return true;
}
// last action: Logout (optional - but without it the router's webconsole is locked for other IPs (e.g. your browser) for some time)
function logout(){
// Post Data

'token' => $this->lastToken,

if ($result['info']['http_code'] != 200 || !$result['body']){

}
// get XML from responseBody

}
}
// Usage Example
$oRouter = new UnitimediaRouter('192.168.0.1');
// $oRouter->debug = true;
if ($oRouter->start() == false){
die('Error Start'); // e.g. Console is locked by an other user
}
if ($oRouter->login('MyPassword')){
// get the table
$sXML = $oRouter->getConnectionTableXML();
if ($sXML){
// use the helper to get an array from XML String (you could also work with SimpleXML / DomXML ;)
$myConnections = UnitimediaRouter::xmlToArray($sXML);
print_r($myConnections);
}
// you should log out to free the web-console
$oRouter->logout();
} else {
die('Error Login'); // e.g. Password is wrong
}
Das funktioniert viel schneller und zuverlässiger als beispielsweise nmap/pings da wirklich alle angemeldeten Geräte aufgelistet werden. Beim Pingen war das anders: Android im Standby z.B. antwortet (bei mir) nicht auf Pings.
Viel Spaß damit.
