vnc默认端口号_什么是VNC远程桌面连接默认端口号？

VNC is a protocol used to connect remote systems with GUI. It is especially popular in Linux world but supports other platforms like Microsoft and MacOS. The default port numbering for multiple VNC services can be tricky for new comers. In this tutorial we will look port and numbering about VNC.

VNC是用于将远程系统与GUI连接的协议。它在Linux世界中特别流行，但支持其他平台，例如Microsoft和MacOS。对于新用户来说，多个VNC服务的默认端口号可能会很棘手。在本教程中，我们将查看有关VNC的端口和编号。

默认端口5900 (Default Port 5900)

The default port for VNC server is TCP 5900 . This port can be changed if we need. Especially if this VNC service is open to the internet or insecure networks changing default port will make our system more secure.

VNC服务器的默认端口是TCP 5900 。如果需要，可以更改此端口。特别是如果此VNC服务对Internet开放或不安全的网络，更改默认端口将使我们的系统更安全。

新的桌面会话端口 (New Desktop Session Port)

We can create new desktop sessions with a single VNC daemon or service. We can configure new desktop and listen new TCP port for the new sessions. Newly added ports will get BASE PORT NUMBER +1 . Which means if BASE PORT NUMBER is 5900 new desktop session will be 5901. This will increment one by one if we add new desktop sessions.

我们可以使用单个VNC守护程序或服务创建新的桌面会话。我们可以配置新的桌面，并为新会话监听新的TCP端口。新添加的端口将获得BASE PORT +1。这意味着如果BASE PORT NUMBER为5900，则新的桌面会话将为5901。如果我们添加新的桌面会话，则它将一一递增。

VNC Web界面端口5800 (VNC Web Interface Port 5800)

VNC can be generally used with desktop client applications. But some VNC server software provides web based client which do not needs VNC desktop client. Web VNC clients generally uses TCP 5800.

VNC通常可以与桌面客户端应用程序一起使用。但是某些VNC服务器软件提供了基于Web的客户端，不需要VNC桌面客户端。 Web VNC客户端通常使用TCP 5800 。

检查默认端口和其他端口 (Check Default and Other Ports)

We can check wheter remote VNC server port is open with telnet . In this example we will check remote system 10.0.2.27 port 5900 is open.

我们可以检查telnet是否打开了远程VNC服务器端口。在此示例中，我们将检查远程系统10.0.2.27端口5900是否打开。

$ telnet 10.0.2.27 5900

We can see that telnet is connected successfully and remote VNC server provided some response like RFB 003.008 which means remote port is a VNC server and up.

我们可以看到telnet连接成功，并且远程VNC服务器提供了一些响应，例如RFB 003.008 ，这意味着远程端口是VNC服务器且处于运行状态。
