title: Check if FTP server is passive or active using Telnet
body: <p>I want to check if my FTP server is active or passive. I only have the server name, user name and password. I tried to adapt this link to do it -<a href="https://stackoverflow.com/questions/3569604/ftp-detect-if-active-or-passive-modes-are-enabled">FTP Detect if active or passive modes are enabled</a></p>
  
  <p>I can connect to this server with a GUI FTP client. But, in microsoft/windows telnet, I used the command <code>o ftp.myftp.com</code>. But, I get the error - <code>Could not open connection to the host on port 23:connect Failed</code>. </p>
  
  <p>How do I fix this and find out if my server is doing active or passive ftp connections ? </p>
