asp+ms sq在线修改SERV—U密码程序参考

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。
