O Que esta de errado com essa classe PHP Telnet ?

ola amigos, aqui uso mikrotik 3.30...num server paralelo rodando LAMP..se eu chamar assim http://192.168.3.101/desconectar.php?UserName=teste

no log do mk mostra "user admin logged in 192.168.3.101 via telnet"
e depois "user admin logged out 192.168.3.101 via telnet

mas não remove o usuario teste.
o que esta errado.

arquivo desconectar.php

Código PHP:

---

<?php
header('Location:http://192.168.0.1');
require_once "PHPTelnet.php";
$usuario = $_GET["UserName"];
$cmdu = "/ip hotspot active remove [find user=".$usuario."]";
$cmdc = "/ip hotspot cookie  remove [find user=".$usuario."]";
$telnet = new PHPTelnet();
$telnet->show_connect_error=0;
 
$result = $telnet->Connect('192.168.0.1','admin','admin');
echo $cmd;
switch ($result) {
case 0:
$telnet->DoCommand($cmdu, $result);
$telnet->DoCommand($cmdc, $result);
$telnet->Disconnect();
break;
case 1:
echo '[PHP Telnet] Connect failed: Unable to open network connection';
break;
case 2:
echo '[PHP Telnet] Connect failed: Unknown host';
break;
case 3:
echo '[PHP Telnet] Connect failed: Login failed';
break;
case 4:
echo '[PHP Telnet] Connect failed: Your PHP version does not support PHP Telnet';
break;
