I. What is SOCKS5 Agent?

Before we start to introduce SOCKS5 proxy settings and application practice, let's first understand what is SOCKS5 proxy.SOCKS5 proxy is a network transport protocol that establishes a secure connection between a client and a server, allowing the client to forward its network requests through the connection and avoiding direct communication with the server. In simple terms, it is like building a bridge between your computer and the server through which you can connect to the Internet while protecting your privacy.

Second, SOCKS5 agent setup steps

Let's take a step-by-step look at how to set up a SOCKS5 proxy under Linux.

1. Installation of Privoxy software

Privoxy is an excellent tool to convert SOCKS5 proxy to HTTP proxy for our Linux system. First of all, we need to install Privoxy software through package management tool. Execute the following command in the terminal:

sudo apt-get install privoxy

2. Configuring Privoxy

Once the installation is complete, we need to make some changes to Privoxy's configuration file. Edit the configuration file `/etc/privoxy/config` and find the following lines:

“`
# Need to remove the comment symbol #
# Enable SOCKS5 Agent
conf_file /etc/privoxy/forwards/forward-socks5.conf
“`

Then save to exit.

3. Create the forward-socks5.conf file

Execute the following command to create and edit the `forward-socks5.conf` file:

sudo touch /etc/privoxy/forwards/forward-socks5.conf
sudo nano /etc/privoxy/forwards/forward-socks5.conf

In the opened file, add the following:

# Fill in the address and port number of your SOCKS5 proxy server
forward-socks5 / 127.0.0.1:1080 .

Note that `127.0.0.1:1080` is the address and port number of the proxy server, which should be changed accordingly.

4. Starting the Privoxy service

Enter the following command to start the Privoxy service:

sudo service privoxy restart

At this point, the setup of the SOCKS5 proxy is complete.

III. Practical application of SOCKS5 agent

With the previous setup in place, we are now ready to actually apply the SOCKS5 proxy.

1. 安装ipipgo客户端

首先，我们需要在本机安装ipipgo客户端来连接SOCKS5代理服务器。在终端中执行以下命令，安装ipipgo客户端：

sudo apt-get install

2. 编辑ipipgo配置文件

执行以下命令，编辑ipipgo配置文件：

sudo nano /etc/.json

In the file that opens, fill in the following configuration:

{
"server": "your_server_ip",
"server_port": 8388,
"local_address": "127.0.0.1",
"local_port": 1080,
"password": "your_password",
"timeout": 300,
"method": "aes-256-cfb"
}

where `your_server_ip` is the IP address of the SOCKS5 proxy server, and `8388` is the port number of the proxy server, which should be changed according to the actual situation. `your_password` is the password for connecting to the proxy server, which also needs to be modified according to the actual situation.

3. 启动ipipgo客户端

输入以下命令，启动ipipgo客户端：

sslocal -c /etc/.json -d start

4. Verify proxy settings

Execute the following command in the terminal to view the current network connection:

curl ipinfo.io

If the output shows the same IP address as `your_server_ip`, then the SOCKS5 proxy is up and running and you are now connecting to the Internet through the proxy network.

Privacy protection and access control of network communication can be realized with SOCKS5 proxy, which is very useful for the scenarios where you need to protect your privacy or break the access restrictions.
