如何使用 php 检查端口 2082 和 2222 以检测服务器的控制面板

Question

如何使用 php 检查端口 2082、2222 以检测服务器的控制面板？

$ports = array(2082 => 'cpanel', 2222 => 'directadmin' , ....);
$panel = "";

foreach($ports as $port => $panelName){
   // some codes for checking the port's
   // if(something)
         $panel = $panelName;
}

对此没有直接的解决方案，您需要实施自己的创意方法。您可能需要检测一个打开套接字的控制面板，而其他使用特定文件存在（例如，Cpanel 将 api 文件放在 php 包含路径上）或任何其他想法。

你可以使用这个类来达到这个目的

namespace Model;

// usage:
//include 'detectControlPanel';
//$object = new \model\detectControlPanel();
//$result = $object->getDetect();
//var_dump($result);

class detectControlPanel
{
public $debug = false;
protected $detect = array();

public function getDetect()
{
    return $this->detect;
}

public function __construct($debug = false)
{
    $this->run();
    $this->debug = $debug;
    $this->debug($this->detect);
}

public function run()
{
    $this->detect['cpanel'] = $this->isCpanel();
    $this->detect['virtualmin'] = $this->isVirtualmin();
    $this->detect['plesk'] = $this->isPlesk();
    $this->detect['directadmin'] = $this->isDirectadmin();
    return $this->detect;
}

private function isCpanel()
{
    try {
        $this->telnet('localhost', 2082);
        return true;
    } catch (\Exception $ex) {
        $this->debug($ex);
        return false;
    }
}

private function isVirtualmin()
{
    try {
        $this->telnet('localhost', 10000);
        return true;
    } catch (\Exception $ex) {
        $this->debug($ex);
        return false;
    }
}

private function isDirectadmin()
{
    try {
        $this->telnet('localhost', 2222);
        return true;
    } catch (\Exception $ex) {
        $this->debug($ex);
        return false;
    }
}

private function isPlesk()
{
    try {
        $this->telnet('localhost', 8443);
        return true;
    } catch (\Exception $ex) {
        $this->debug($ex);
        return false;
    }
}

private function debug($input)
{
    if ($this->debug == true) {
        if (gettype($input) == 'string') {
            echo '<br>' . "\n";
            echo $input;
            echo '<br>' . "\n";
        } elseif (gettype($input) == 'array') {
            echo '<pre>' . "\n";
            print_r($input);
            echo '</pre>' . "\n";
        } elseif (gettype($input) == 'object' && get_class($input) == 'Exception') {
            echo '<pre>' . "\n";
            echo $input->getMessage();
            echo '</pre>' . "\n";
        } else {
            var_dump($input);
        }
    }
}

private function telnet($hostname, $port)
{
    if (!$hostname)
        throw new \Exception("empty host name");
    if (!$port)
        throw new \Exception("empty port number");
    $ipAddress = gethostbyname($hostname);
    $link = @fsockopen($ipAddress, $port, $errno, $error);
    if ($error) {
        throw new \Exception($error, $errno);
    }
    if ($link) {
        return true;
    }
    return false;
}
}
