使用FTP Serv-U安装FTPSERVER的朋友，可以使用Serv-U符号信息参数来向CLIENT端显示一些重要的信息。
比如：
Mon Dec 10 22:32:46 2001 220-==============================

这些可以显示的信息包括：
Sign-on/sign-off messages 签入/出信息
User specific login messages 用户指定登录信息
Directory change messages 目录改变信息
你可以往这些指定的信息文本里加入符号参数，这些参数在发送给客户时会扩展为当前状态的内容。

以下是有关配额的显示
%QuotaUsed - displays how much disk quota is used in Kb 显示配额已使用部分
%QuotaLeft - displays how much disk quota is left in Kb 显示配额剩余部分
%QuotaMax - displays the maximum amount of disk space that can be used in Kb Number of users: 磁盘最大可用字节数
%UNow - displays the current number of Serv-U users connected 当前连接在服务器上的人数
%UAll - displays the number of users since the server was started 本次启动以来连接过本服务器的用户数
%U24h - displays the number of users in the last 24 hours 二十四小时以来连接过本服务器的用户数

%UThisName - all current users with the current user name logged into this IP home下
下面是一个例子:
欢迎你在趖e %time 访问我们的服务器, 你是第 %unow 个用户，最大
用户数为 %maxusers，在上24小时以来，共有 %u24h个朋友访问这里。
注意，CLIENT端每行只显示80个字符，而返回码就占了4个字符。所以，建议定义信息每行最多70个字符。
建议：自建FTP的朋友，建议多使用下面的符号：
%Disk - 用户当前磁盘驱动器
遰ee - 用户当前剩余空间（KB）
%QuotaMax - 最大可用磁盘空间（KB）
以便给上传的朋友知道现在的空间可用情况 。
当然可以设置限额：
Menu-->setup--->users...---->Quota: Enable disk quota: Maximum: XXXMB
这样可以用
%QuotaUsed - 已使用多小配额空间（KB）
%QuotaLeft - 还有多小配额空间可以用(kb)
%QuotaMax - 设定的配额
建议是在登入信息和目录改变信息里加入这些宏，这样使用FTP人会方便很多。

The file upload and download message directives are for the current session only (i.e. they do not show the aggregate over multiple sessions).
The '%ServerDays', '%ServerHours', '%ServerMins', and '%ServerSecs' directives are meant for use together. The number of hours is what's left after the number of days is subtracted, and the same goes for the number of minutes and seconds.
Example Message
Welcome to ftp.cat-soft.com, home of Serv-U!
Local time is %time, and %u24h users have visited over the last 24 hours. This server has been up for %ServerDays days, %ServerHours hours, %ServerMins min. and %ServerSecs sec.

Please keep in mind that the average client has only 80 characters per line, and the first four are taken up by the reply code. Please be brief, 70 characters should generally be considered a safe maximum.
