ASP+MS SQL在线修改Serv-u的密码教程-ASP教程,ASP应用

下面是以serv-u 6.0和sql server 2000相结合的演示。

建表sql 语句：

create table [groupaccounts] (
 [id] int identity (1,1) primary key,
 [index] int default 0,
 [name] nvarchar(50) default ,
 [notes] nvarchar(255) default
 )
create index [name] on [groupaccounts]([name] )

create table [groupdiraccess] (
 [id] int identity primary key,
 [access] nvarchar(255) default ,
 [index] int default 0,
 [name] nvarchar(50) default
 )
create index [name] on [groupdiraccess]([name] )

create table [groupipaccess] (
 [id] int identity primary key,
 [access] nvarchar(255) default ,
 [index] int default 0,
 [name] nvarchar(50) default
 )
create index [name] on [groupipaccess]([name] )

create table [useraccounts] (
 [id] int identity primary key,
 [access] nvarchar(255) default ,
 [alwayslogin] int default 0,
 [changepass] int default 0,
 [disable] int default 0,
 [expirationtype] int default 0,
 [expiration] datetime default 1980-1-1,
 [groups] nvarchar(50) default ,
 [hidehidden] int default 0,
 [homedir] nvarchar(100) default ,
 [idletimeout] int default 0,
 [logmesfile] nvarchar(100) default ,
 [maxip] int default -1,
 [maxspeeddown] decimal default 0,
 [maxspeedup] decimal default 0,
 [maxusers] int default -1,
 [name] nvarchar(50) default ,
 [needsecure] int default 0,
 [notes] nvarchar(255) default ,
 [passtype] int default 0,
 [password] nvarchar(50) default ,
 [privilege] int default 0,
 [quotacurrent] decimal default 0,
 [quotaenable] int default 0,
 [quotamax] decimal default 0,
 [ratiocredit] decimal default 0,
 [ratiodown] int default 0,
 [ratiotype] int default 0,
 [ratioup] int default 0,
 [relpaths] int default 0,
 [sessiontimeout] int default 0,
 [skeyvalues] nvarchar(50) default
 )
create index [name] on [useraccounts]([name] )

create table [userdiraccess] (
 [id] int identity primary key,
 [access] nvarchar(255) default ,
 [index] int default 0,
 [name] nvarchar(50) default
 )
create index [name] on [userdiraccess]([name] )

create table [useripaccess] (
 [id] int identity primary key,
 [access] nvarchar(255) default ,
 [index] int default 0,
 [name] nvarchar(50) default
 )
create index [name] on [useripaccess]([name] )

servudaemon.ini中的odbc信息：
odbcsource=serv-u||
odbctables=useraccounts|groupaccounts|userdiraccess|groupdiraccess|useripaccess|groupipaccess
odbccolumns=name|password|skeyvalues|homedir|logmesfile|access|disable|needsecure|relpaths|hidehidden|alwayslogin|changepass|quotaenable|maxip|maxspeedup|maxspeeddown|maxusers|idletimeout|sessiontimeout|ratioup|ratiodown|ratiocredit|quotacurrent|quotamax|expiration|privilege|passtype|ratiotype|groups|notes|index

我们利用serv-u的obdc功能，可以把ftp用户信息存在数据库中，这样对web操作方便了很多，下面是在线更改密码的列子，数据库为access，表和字段的设计请参考serv-u的帮助文件。

加密算法为随机码与md5 32 位加密，例如：
两个随机字母：ab
用户输入密码：123456
生成的密码为：ab + md5(ab123456)

补充：md5返回为32位的大写字符，附md5.asp

提示：代码仅实现更改密码的功能，并不一定完全符合或达到您的需求。

function myrandc(n)生成随机字符，n为字符的个数
 thechr = “”

  randomize timer

 next
 myrandc = thechr
