求助,配置wu-ftp出现问题

sirrus

初次使用wu-ftp,shell下测试出现了下面的情况:
ftp> open 192.168.8.10
Connected to 192.168.8.10.
220 liuxz FTP server (Version wu-2.6.2- ready.
504 AUTH GSSAPI not supported.
504 AUTH KERBEROS_V4 not supported.
KERBEROS_V4 rejected as an authentication type
Name (192.168.8.10:root): anonymous
331 Guest login ok, send your complete e-mail address as password.
Password:
530 Login incorrect.
Login failed.
ftp>
其中
504 AUTH GSSAPI not supported.
504 AUTH KERBEROS_V4 not supported.
不知道什么意思,还有我用anonymous登录为什么还要用e-mail作密码,我输入了
ftpaccecc.conf里面的# Set this to your email address
email root@localhost的e-mail作为密码出现了530 Login incorrect.
Login failed.
这是为什么啊??初次使用,请多指教,不胜感激
