FTP problem

[Hans]

Hi
I have installed Ubuntu and I am trying to set up a FTP server. I use 
proftpd . connecting from a windows machine using filezilla work fine 
but connecting from the same machine running Ubuntu and gftp will 
terminate the session. Please se print below for session messages:

Looking up xxx.xxx.xxx.xxx
Trying xxx.xxx.xxx.xxx:21
Connected toxxx.xxx.xxx.xxx:21
220 ProFTPD 1.2.10 Server (Debian) [192.168.1.2]
USER xxxxx

PASS xxxx

SYST

257 "/" is current directory.
Loading directory listing / from server (LC_TIME=en_US.UTF-8)
PASV
Error: Could not read from socket: Connection reset by peer
Disconnecting from site xxx.xxx.xxx.xxx

Any ideas how to fix this?
