title: SFTP listing directory
body: <p>I'm trying to make a connection to a secure sftp site, however I'm not able to list the directory,however, it's possible to connect using python "expect" or php"ssh2_connect" but it gives me the following mesg: Received disconnect from xx.xx.xx.</p>
  
  <p>If I use a GUI appliction like winscp I'm able to go to the sftp server and retrieve files.</p>
  
  <p>I need to script it thus a cli interface is needed.</p>
  
  <p>PS: just in case someone ran into this. I'm trying to connect to Avisena.com  sftp server</p>
