Traffic IS getting to the FTP server, because I can login. The thing is when
I have logged in and the client sends the LIST command it can't read the
directory and closes the connection. As discribed here:

_______________________________________
Can't build data connection: interrupted system call.
ABOR command succesfull.
Connection Lost
_______________________________________

So, connection TO the server seems to work but when the server tries to SEND
traffic to the client it fails.
