ftp connection problem in fc1

[Barry Yu]

using fc1 try to connect a ftp server, below are the steps and what were 
displayed ;
ftp ftp.servername.org
(Can see Welcome banner as logged in successfully.)
ftp> ls
227 Entering passive mode (192,168,1,111,240)
426 Connection closed; transfer aborted.

And that's the end of it - first got connected, and then when issued 
command ls, the connection is closed.
What was wrong?
