wu-ftp限速问题

以下是我的ftpaccess文件

# This file controls the behavior of the wu-ftpd
# ftp server.

# editing it, try kwuftpd from the kdeadmin
# package.

# The ftpchroot group doesn't exist by default, this

# You will need to setup the required applications
# and libraries in the root directory (set using
# guest-root).

最后两句是限速的，但是加上这两句后，就不能上传和下载了
注释掉这两句后一切正常
请问怎样才能限速？

天下文章一大抄

在/etc/ftpaccess里面加上：
throughput /home/ftp * * 64000 0.5 *

意思是下载带宽对所有IP(最后那个*)限制在64K，每下一个文件速度减半(那个0
.5)．

这个语句根本就不起左右啊
真是天下文章一大抄啊。
就连wu-ftpd.org的FAQ也没有对限速有个很好的阐述，真是失望啊。

不太清楚啊~~
