VNC allows you to remotely access a computer and use its desktop, either over the Internet or from another room in your house. Windows includes a Remote Desktop feature, but it’s only available in Professional editions of Windows.

通过VNC，您可以通过Internet或从房屋中的另一个房间远程访问计算机并使用其桌面。 Windows包括远程桌面功能 ，但仅在Windows专业版中可用。

Some people may prefer TeamViewer or another service instead, but VNC allows you to install and manage your own server without using a centralized service. VNC clients and servers are available for all platforms, but we’ll be covering Windows here.

有些人可能更喜欢TeamViewer或其他服务，但是VNC允许您在不使用集中式服务的情况下安装和管理自己的服务器。 VNC客户端和服务器可用于所有平台，但此处将介绍Windows。

安装VNC服务器 (Install a VNC Server)

First, you’ll need to install a VNC server on the computer you want to access remotely. We’ll be using TightVNC here, but there are other VNC servers you can also use, such as UltraVNC.

首先，您需要在要远程访问的计算机上安装VNC服务器。 我们将在这里使用TightVNC ，但您也可以使用其他VNC服务器，例如UltraVNC 。

TightVNC installs itself as a system service by default, so it will always be running in the background as long as your computer is on. (Of course, you can always disable the service manually.) It also automatically allows itself in the Windows firewall – if you use a different firewall, ensure that the firewall isn’t blocking TightVNC or you won’t be able to connect.

TightVNC默认将自身安装为系统服务，因此只要您的计算机处于打开状态，它就始终在后台运行。 (当然，您始终可以手动禁用该服务。)它还会自动允许其进入Windows防火墙-如果您使用其他防火墙，请确保防火墙不会阻止TightVNC或无法连接。

Be sure to secure your VNC with a strong password, especially if you’re exposing your VNC server to the Internet!

确保使用强密码保护VNC，尤其是在将VNC服务器暴露于Internet的情况下！

After the quick installation process, TightVNC will now be running on your computer. You can use the TightVNC Service – Control Interface option in your Start menu to configure your server.

快速安装过程之后，TightVNC现在将在您的计算机上运行。 您可以使用“开始”菜单中的“ TightVNC服务–控制界面”选项来配置服务器。

One important setting you’ll want to change is the ports TightVNC uses. The default port used for VNC is 5900 – you can increase your security by changing it to another port. People scanning for open VNC servers will try t o connect at port 5900, ut generally won’t notice VNC servers running on other random ports, such as 34153.

您要更改的一项重要设置是TightVNC使用的端口。 VNC的默认端口是5900-您可以通过将其更改为另一个端口来提高安全性。 扫描开放的VNC服务器的人们将尝试在端口5900上进行连接，但通常不会注意到在其他随机端口(例如34153)上运行的VNC服务器。

You may also want to change the Web Access port for the same reason — or disable web access entirely.

出于相同的原因，您可能还想更改Web访问端口-或完全禁用Web访问。

转发端口并设置动态DNS (Forward Ports & Set Up Dynamic DNS)

Your computer is now running a VNC server, so you’ll be able to connect to it from other computers on your local network. If you want to connect to it from the Internet, you’ll have to do a few more things.

您的计算机现在正在运行VNC服务器，因此您可以从本地网络上的其他计算机连接到该服务器。 如果要从Internet连接到它，则必须做更多的事情。

First, you’ll need to forward the VNC server’s port on your router. This process is different on every router, but you’ll have to use your router’s web interface to forward ports.

首先，您需要在路由器上转发VNC服务器的端口。 每个路由器的此过程都不同，但是您必须使用路由器的Web界面转发端口。

You may also want to set up a dynamic DNS hostname for your home network. Internet service providers often change the IP address assigned to home networks, which means that you may be unable to connect to your home computer if your home IP address changes.

您可能还需要为家庭网络设置动态DNS主机名。 Internet服务提供商经常更改分配给家庭网络的IP地址，这意味着如果您的家庭IP地址发生更改，您可能无法连接到家庭计算机。

连接到您的计算机 (Connect to Your Computer)

With a VNC server running on the remote computer, you can use a VNC client on another computer to connect. TightVNC includes a VNC client – you can install TightVNC on another computer and deselect the server option in the install process to only install the viewer. Once it’s installed, you’ll find the TightVNC Viewer in your Start menu.

使用在远程计算机上运行的VNC服务器，您可以使用另一台计算机上的VNC客户端进行连接。 TightVNC包含VNC客户端–您可以在另一台计算机上安装TightVNC，并在安装过程中取消选择服务器选项，仅安装查看器。 安装完成后，您将在开始菜单中找到TightVNC Viewer。

Enter the address of your home computer to connect. You can use several different types of addresses:

输入您要连接的家用计算机的地址。 您可以使用几种不同类型的地址：

• Use the computer’s local IP address if you’re on the same local network as the computer.如果您与计算机位于同一局域网中，请使用计算机的本地IP地址。
• Use your home network’s IP address if you’re accessing the computer over the Internet.如果要通过Internet访问计算机，请使用家庭网络的IP地址。
• Use your dynamic DNS hostname if you set up dynamic DNS and are accessing your computer over the Internet.如果您设置了动态DNS，并且正在通过Internet访问计算机，请使用动态DNS主机名。

If you’re using a different port for your VNC server (as you probably should be), append the port number after two colons.

如果您正在为VNC服务器使用其他端口(可能应该使用)，请在两个冒号后面附加端口号。

After connecting, you’ll see the remote computer’s desktop in a window on your screen.

连接后，您将在屏幕上的一个窗口中看到远程计算机的桌面。
