FTP not working/active after following guide (Debian)

Hi,

I followed: http://www.howtoforge.com/perfect-server-debian-squeeze-with-bind-and-courier-ispconfig-3-p6. But right now, when I check the control panel it says that the FTP server is not online.

What to do?

 

What's the output of

Code:

netstat -tap

?

 

Solved it, I guess. I stopped using TLS, after that the FTP-server ran correctly. (echo 0 > /etc/pure-ftpd/conf/TLS)
