title: What is the syntax of the FTP log file
body: <p>I'm trying to go through some of my FTP logs to examine an issue I've experienced. But the log files have some shorthand flags, I don't know what they mean, and I am unable to find any sort of documentation on it. </p>
  
  <p>An example of a line from the FTP log is:</p>
  
  <pre><code>Tue Jan 05 17:18:22 2016 0 1.2.3.4 3581 /path/to/file/file.php a _ o r username ftp 1 * c
  </code></pre>
  
  <p>Date and time are obvious, <code>1.2.3.4</code> would be my IP address, <code>3581</code> I'm assuming is the Linux PID, <code>username</code> is my FTP account username. </p>
  
  <p>The ending of the line, <code>a _ o r username ftp 1 * c</code> (except for <code>username</code> and <code>ftp</code>) is what I'm most confused about. And the <code>0</code> between the date and my IP address. </p>
  
  <p>Is there any documentation somewhere about what all those flags represent? </p>
