proftpd能启动，但是用gftp打不开？？？

我在红旗桌面版上编译安装了proftpd-1.2.9，安装启动一切顺利！但是用gftp连接的时候显示：
查找 localhost.localdomain
尝试 localhost.localdomain:21
连接到 localhost.localdomain:21
220 ProFTPD 1.2.9 Server (ProFTPD Default Installation) [localhost.localdomain]
USER anonymous
331 Anonymous login ok, send your complete email address as your password.
PASS xxxx
530-Unable to set anonymous privileges.
530 Login incorrect.
正在断开与服务器 localhost.localdomain 的连接
这是什么问题呀？请帮帮我呀！
