Ubuntu Global Proxy Configuration Tutorial

嘿，亲爱的Ubuntu用户们，今天我们要来讨论一个非常有趣而又实用的话题——全局代理配置。作为一名Ubuntu爱好者，我深知在使用Ubuntu时有时难免需要翻越网络封锁的那堵高。离开了它，我们无法享受到外面那片互联网的美好。在这篇文章中，我将向大家详细介绍如何在Ubuntu上配置全局代理，帮助大家自由访问互联网的世界。

Why you need a global agent

在深入探讨全局代理配置之前，让我们先来了解一下它为什么如此重要。相信很多Ubuntu用户都有过这样的经历，当你想要访问一些国内的网站或服务时，可能会遇到速度慢、无法访问、被封锁等问题。这是因为某些原因，比如地理位置限制、网络封锁等，我们无法直接与国内的服务器建立连接。

而全局代理的作用就是帮助我们突破这种限制，让我们能够自由地访问被封锁的网站、加速访问国内服务器，以及保护我们的隐私安全。通过配置全局代理，我们可以将我们的网络流量发送到代理服务器，再由代理服务器帮助我们请求目标服务器上的资源，从而实现访问自由。

How to Configure Global Proxy

Okay, without further ado, let's get started with configuring the global proxy! First, we need to find the network settings of your Ubuntu system. You can click on the network icon in the top right corner and select "Network Settings", or just search for "Settings" in the application menu to open the system settings.

Next, we find the "Network" tab and click on it to enter the network settings page. Here, we can see the currently connected network interface, as well as the configuration options for the network proxy. Remember, we are configuring a "Global" proxy, so we need to select "Manual" as the proxy type.

在代理服务器一栏中，我们需要填写代理服务器的地址和端口号。通常，你需要购买或使用免费的代理服务，并从他们那里获得代理服务器的地址和端口号。以ipipgo为例，它是一个非常常用的代理工具，你可以在其官方网站上找到相应的信息。

After filling in the proxy server address and port number, we can click "Apply to Entire System" to make the configuration take effect globally. At this point, you will be asked to enter your account and password, this is because you need administrator privileges to modify the system's network settings.

Congratulations, you have successfully configured the global proxy! Now, try to open a website you couldn't access before, and you'll see that everything works smoothly and picturesquely, as if you were in a free online world.

Some Frequently Asked Questions and Notes

When configuring a global proxy, you may encounter some problems. Here, I list some common problems and countermeasures to help you successfully complete the configuration.

1. Unstable proxy server: Some free proxy servers may be unstable or slow. At this time, you can try to change to another proxy server or choose to buy a stable proxy service.

2. Privacy and security issues: When using a proxy server, we should pay attention to protecting our privacy and security. Always choose a trustworthy proxy service provider and avoid entering web forms containing sensitive personal information on the proxy server.

3. Browser Proxy Settings: After configuring the global proxy, you may also need to manually modify the proxy settings of your browser to make the proxy effective. You can refer to the official documentation of the browser you are using for details.
