局域网唤醒 外网无法唤醒

As an IT manager, there are a lot of things you can do which directly impact your company’s bottom line. While the most obvious are direct hardware and software costs, an often overlooked aspect is energy/electricity consumption by computer systems. While servers need to be available 24/7, desktop systems only need to be available when the respective user needs it or for scheduled maintenance tasks. The rest of the time (usually more than 50% of the time), the system can stay in low power mode which reduces power usage, hence cost.

作为IT经理，您可以做很多事情，这些事情都会直接影响公司的利润。 虽然最明显的是直接的硬件和软件成本，但经常被忽视的一个方面是计算机系统的能源/电力消耗。 尽管服务器需要24/7全天候可用，但桌面系统仅在相应用户需要它或用于计划的维护任务时才需要可用。 在其余时间(通常超过50％的时间)中，系统可以保持在低功耗模式，这会减少功耗，从而降低成本。

While Windows systems have options to wake themselves to run scheduled tasks, if users access their systems remotely (i.e. Remote Web Workplace) there is not an easy way for the system to be awakened on demand. The solution is implementing a Wake on LAN system such as the free ASP.NET Wake on LAN Control Panel. Through this, client computers can be brought out of standby with the simple click of a button. This makes is an ideal solution for finding a balance between availability and power savings.

尽管Windows系统具有唤醒自己以运行计划任务的选项，但是如果用户远程访问其系统(即Remote Web Workplace)，则没有一种简便的方法可以按需唤醒系统。 该解决方案正在实施Wake on LAN系统，例如免费的ASP.NET Wake on LAN控制面板。 这样，只需单击一下按钮，即可使客户端计算机退出待机状态。 这是在可用性和节能之间找到平衡的理想解决方案。

要求 (Requirements)

• SQL 2005/2008 (Express or Full) must be installed in your network. Out of the box, the ASP.NET Wake on LAN Control Panel is configured to use SQL Express with user instances but we will show you how to use the full version of SQL Server as well.您的网络中必须安装SQL 2005/2008(Express或Full)。 开箱即用，将“ LAN控制面板上的ASP.NET唤醒”配置为对用户实例使用SQL Express，但是我们还将向您展示如何使用完整版SQL Server。
• Desktop computers must be configured with the ability to be awakened remotely. Typically, this is the default setting for your network card but if you want to be sure, you can check the device properties of your network card in Device Manager.台式计算机必须配置为具有远程唤醒功能。 通常，这是网卡的默认设置，但是如果要确定，可以在“设备管理器”中检查网卡的设备属性。
• Overall, the documentation which is downloadable from from the ASP.NET Wake on LAN page is very good. It covers using the installer to set everything up, but in true geek fashion we are going to set up everything manually.总体而言，可从ASP.NET LAN唤醒页面下载的文档非常好。 它涵盖了使用安装程序来设置所有内容的步骤，但是以真正的怪胎方式，我们将手动设置所有内容。

设置局域网唤醒控制面板 (Setup the Wake on LAN Control Panel)

Create the folder “C:inetpubwwwrootWakeOnLan” and extract the contents of the Wake on LAN zip package.

创建文件夹“ C：inetpubwwwrootWakeOnLan”，然后提取Wake on LAN zip软件包的内容。

Open the “Web.config” file and note the connectionStrings section:

打开“ Web.config”文件，并注意connectionStrings部分：

<connectionStrings> <!– Use this connection string for connecting to a SQL 2005/2008 server –> <!–<add name=”WakeOnLanConnectionString” connectionString=”Data Source=.;Initial Catalog=WakeOnLan;Integrated Security=SSPI” providerName=”System.Data.SqlClient”/>–>

<connectionStrings> <！–使用此连接字符串连接到SQL 2005/2008服务器–> <！– <添加名称=“ WakeOnLanConnectionString” connectionString =”数据源= .;初始目录= WakeOnLan;集成安全性= SSPI” providerName =“ System.Data.SqlClient” /> –>

<!– Use this connection string for using the local database with SQLExpress –> <add name=”WakeOnLanConnectionString” connectionString=”Data Source=.SQLExpress;Integrated Security=True;AttachDBFilename=|DataDirectory|WakeOnLan.mdf;User Instance=true”/> </connectionStrings>

<！–使用此连接字符串将本地数据库与SQLExpress一起使用–> <add name =“ WakeOnLanConnectionString” connectionString =“ Data Source = .SQLExpress; Integrated Security = True; AttachDBFilename = | DataDirectory | WakeOnLan.mdf;用户实例= true ” /> </ connectionStrings>

If you are using SQL Express with user instances enabled (default option during the installation of SQL Express) on the local machine you do not have to modify anything and can ignore the rest of this section, however if you are using the full version of SQL or have SQL Express user instances disabled, you will need comment out/delete the second connectionString key and uncomment the first and save your changes. By default, the SQL Server connection string is set to use the local computer with trusted authentication. Depending on your environment, you may want/need to alter these connection settings.

如果在本地计算机上使用启用了用户实例SQL Express(SQL Express安装期间的默认选项)，则无需修改任何内容，并且可以忽略本节的其余部分，但是，如果您使用的是完整版SQL或禁用了SQL Express用户实例，则需要注释掉/删除第二个connectionString键，并取消注释第一个并保存更改。 默认情况下，SQL Server连接字符串设置为使用具有受信任身份验证的本地计算机。 根据您的环境，您可能希望/需要更改这些连接设置。

The ASP.NET Wake On Lan package includes a SQL database creation script to use for setup on SQL Server. Before running this script, you will need to make one minor correction to the the SQL file. Open the file “C:inetpubwwwrootApp_DataSchema.sql” in Notepad and add “WakeOnLan” in the location highlighted:

ASP.NET Lan唤醒程序包包括一个SQL数据库创建脚本，可用于在SQL Server上进行安装。 在运行此脚本之前，您需要对SQL文件进行一些小的更正。 在记事本中打开文件“ C：inetpubwwwrootApp_DataSchema.sql”，并在突出显示的位置添加“ WakeOnLan”：

Once this is done, save the changes and then run the install script as a Windows Administrator (where –S “.” specifies the SQL Server to install to):

完成此操作后，保存更改，然后以Windows管理员身份运行安装脚本(其中-S“。”指定要安装到SQL Server)：

SqlCmd -S “.” -E -i “C:inetpubwwwrootApp_DataSchema.sql”

SqlCmd -S“。” -E -i“ C：inetpubwwwrootApp_DataSchema.sql”

配置IIS以运行LAN唤醒控制面板 (Configure IIS to Run the Wake on LAN Control Panel)

Once you have the files and database in place open Internet Information Services Manager. Under the ‘Default Web Site’ you should see the WakeOnLan folder. Before the control panel can be used, you must convert the directory to an application which runs on .NET version 2.0.

将文件和数据库放置到位后，打开“ Internet信息服务管理器”。 在“默认网站”下，您应该看到WakeOnLan文件夹。 在使用控制面板之前，必须将目录转换为在.NET 2.0版上运行的应用程序。

In IIS 7, you simply need to right click on the folder and select ‘Convert to Application’. In IIS 6, you need to use the ‘Add Application Wizard’ which is available by right clicking on the ‘Default Web Site’.

在IIS 7中，您只需要右键单击该文件夹，然后选择“转换为应用程序”。 在IIS 6中，您需要使用“添加应用程序向导”，可通过右键单击“默认网站”来使用。

The default settings of the application are typically correct and do not need to be modified.

该应用程序的默认设置通常是正确的，不需要修改。

Once the application is created, you should be able to access the ASP.NET Wake on LAN Control Panel by visiting “http://localhost/WakeOnLan”. If this does not work, check to make sure:

创建应用程序后，您应该能够通过访问“ http：// localhost / WakeOnLan”来访问LAN控制面板上的ASP.NET唤醒。 如果这不起作用，请检查以确保：

• The IIS WakeOnLan application is running in a .NET 2.0 AppPool.IIS WakeOnLan应用程序在.NET 2.0 AppPool中运行。
• Your SQL connection strings are correct in your Web.config file.您的Web.config文件中SQL连接字符串正确。

新增电脑 (Adding Computers)

Once you have set up the control panel, all that is left is to add computers. This is pretty intuitive, just click the ‘Add New Computer’ link and enter either the computer name or local IP address of the system to add.

设置好控制面板后，剩下的就是添加计算机。 这非常直观，只需单击“添加新计算机”链接，然后输入要添加的系统的计算机名称或本地IP地址。

The MAC Address will automatically be resolved and the new computer will appear in the list.

MAC地址将自动解析，新计算机将出现在列表中。

使用局域网唤醒控制面板 (Using the Wake on LAN Control Panel)

Usage of the ASP.NET Wake on LAN Control Panel is incredibly intuitive. When you access the page, the status of the connected computers is scanned and presented.

局域网控制面板上ASP.NET唤醒的用法非常直观。 当您访问该页面时，将扫描并显示已连接计算机的状态。

• Computers which are active/awake, are presented in blue.处于活动/唤醒状态的计算机以蓝色显示。
• Computers which are asleep (standby/hibernation) are presented in black.睡眠(待机/Hibernate)的计算机以黑色显示。
• Computers which are waking up are yellow.正在唤醒的计算机为黄色。

To wake a computer, simply click the appropriate link.

要唤醒计算机，只需单击相应的链接。

The computer will turn yellow and a few minutes later, it will turn blue. After about 30 seconds, the computer which was asleep is now ready to be accessed.

电脑将变成黄色，几分钟后，它将变成蓝色。 大约30秒钟后，现在可以访问处于睡眠状态的计算机。

结论 (Conclusion)

The ASP.NET Wake on LAN Control Panel can easily be made available outside your network. As long as the IIS web site you have configured it in is available externally, you can access the control panel from http://www.domain.com/WakeOnLan. You would just need to train your users to access this page prior to connecting to their computer. For example, by adding a link to a company portal to access the control panel can minimize the “how do I do that again?” questions.

可以轻松在网络外部使用ASP.NET Wake on LAN控制面板。 只要您已在其中配置了IIS的网站可以从外部访问，就可以从http://www.domain.com/WakeOnLan访问控制面板。 您只需要培训用户以在连接到他们的计算机之前访问此页面。 例如，通过将链接添加到公司门户以访问控制面板，可以最大程度地减少“我该怎么做？” 问题。
