Hi,
I want to run an Active FTP server with vsftpd service on SuSE 10 Enterprise Server ...

my vsftpd.conf file :
=====================================
anonymous_enable=NO
chroot_local_user=YES
listen=YES
local_enable=YES
pam_service_name=vsftpd
pasv_enable=NO
pasv_promiscuous=YES
session_support=NO
use_localtime=YES
xferlog_enable=YES
async_abor_enable=YES
connect_from_port_20=YES
download_enable=NO
local_umask=0027
=====================================
With this configuration I can ftp with shell but can't ftp using firefox and give me an error : "550 permission denied" .
Also when I ftp with shell , I run a command on server : "netstat -na | grep -i :20" and my port 20 is not open for this Active FTP !!!
I have no use any firewall : iptables or rcSuSEfirewall2 and my network not closed for ports 20 , 21 .

Where is my mistake ?!
