I'm making an application based laravel that allows it to communicate with a linux server via SSH, I usually use phpseclib to communicate with servers such as rebooting and others, but when I build the application with laravel I could not or would rather not see the way how to integrate with laravel I tried to include manual of php but still could not error Class 'phpseclib\Net\ Net_SSH2' not found, my current code

    public function store(Request $request)
{
    // create ssh account and inserted into database here
    if(Auth::check()) // make sure user has been logging on
    {
      if($dump = DB::table('servers')->where('key', $request->_key)->get())
      {
        if($prices = DB::table('app_data')->get())
        {
          $price = $prices[0]->prices;
          if(DB::table('ssh_users')->where('name', $request->sshname)->where('on_server', $dump[0]->ip)->count() > 0 )
          {
            return view('create')->with('userexist', $request->sshname);
          }
          else
          {
            include(app_path() . "/lib/phpseclib/phpseclib/phpseclib/Net/SSH2.php");
            $command = new \phpseclib\Net\Net_SSH2($dump[0]->ip);
            $valid = array(
              'sshuser'     => $request->sshname,
              'sshpass'     => $request->sshpass,
              'sshcreated'  => date('d/m/Y'),
              'sshexpired'  => $request->sshexpired,
              'onserver'    => $dump[0]->name,

              'sshprice'    => $price,
              'command'     => $command
            );

      }
      else
      {
        return view('create')->with('serverabort', $request->sshname);

Answer 1

Solution 1:

Check /lib/phpseclib/phpseclib/phpseclib/Net/SSH2.php and note what class name is used, it may be SSH2, and not Net_SSH2 (pre PSR-4 namespacing).

Then update the line, e.g. to:

$command = new \phpseclib\Net\SSH2($dump[0]->ip);

Solution 2:

Install phpseclib as a composer package

composer require phpseclib/phpseclib

Then it will be autoloaded and you won't need the include()
