Checking my server, I’m running vsftp version 3.0.2-6.

Here’s what my vsftp.conf file looks like:

anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
xferlog_std_format=YES
listen=YES
pam_service_name=vsftpd
userlist_enable=NO
tcp_wrappers=YES

The only other things I can think of are:
[LIST]
[]to make sure the vsftp service is enabled, not just running, so that when you reboot your server it starts automatically
[]make sure the username and password are correct, not only under the FOG settings of the web interface, but also under Storage Management and in the your …/fog/comons/config.php file
[LIST]
[]in the config.php file, make sure the TFTP and STORAGE FTP username and password (the password may be encrypted) are set to your values
[/LIST]
[]if your firewall is on, make the appropriate exceptions for vsftp, or you can disable it completely
[/LIST]
Hope that helps.

Thanks for your replay. I upgrade from 1.1.1 to 1.2.0. I fixed the problem! During the installation, I was asked if I left MySQL password blank, I said no and then left the passwords in blank again. This probably overwrite the php file which was previously creating a password when I said yes.

Thanks
