title: FTP file list access not allowed from azure VM
body: <p>I have redhat linux Azure VM server through which I am trying to get directory listing from FTP server hosted on other windows Azure VM. I could connect through FTP using my local machine and filezilla and get the directory listing, But I am getting error for both active and Passive connection through my redhat linux azure VM server while using ls command.</p>
  
  <p><strong>Active connection error :</strong>
  ftp: accept: Resource temporarily unavailable
  425 Can't open data connection for transfer of "/"
  226 ABOR command successful</p>
  
  <p><strong>Passive error:</strong>
  227 Entering Passive Mode (10,1,0,10,160,87)
  ftp: connect: Connection timed out</p>
  
  <p>It looks like more of firewall issue but what kind of setting I need to change. I have also added FTP port 21 and data connection port 20 in my inbound rules. </p>
  
  <p>In my firewalld rule FTP service is listed. Even all passive connection port is also added. Also I Disabled firewalld and then tried but no success.</p>
  
  <p>I need to access this FTP from my PHP page to get all the files uploaded on FTP folder.</p>
  
  <p>Thanks</p>
