cannot ftp into opensuse 11.3 with LXDE

I setup an opensuse 11.3 with LXDE.
This system has ipv6 disabled and the firewall permits ftp.
When I tried to ftp into this system, it fails with the following message in the console.
Any advice is greatly appreciated.

$ ftp 192.168.1.123
Connected to 192.168.1.123.
500 OOPS: could not bind listening IPv6 socket

What is the result of:

/sbin/ifconfig

?

ifconfig
