FTP Server hangs at MLSD command when accessing with Filezilla Print

In case if you’re faced with  similar problems of not being able to access your server as it hangs at the MLSD stage, this is what I’ve done:

1. Login to the server using SSH as root user
2. Open the file /etc/pure-ftpd.conf
3. Scroll down and look for the line that says “PassivePortRange 30000 35000″
4. Make sure it is not commented out (with a # at the front)
5. Save the file
6. Restart the FTP server
