 # gotproxy
 
-A simple transparent proxy for Linux that routes network traffic based on the specific process command name.
+[简体中文](./README_CN.md) | English
+
+This is a simple transparent proxy tool developed in Go, leveraging eBPF. It enables transparent proxying for network traffic either globally or targeted by specific IP addresses, process IDs, or process name.
+
+The program offers direct transparent proxy network forwarding with SOCKS5 support, serving as a modern alternative to tools like redsocks and proxychains. Furthermore, it can be integrated with other proxy software or Layer 7 proxies to implement advanced functionalities such as traffic splitting, firewalls, or creating a Mock Server.
 
 ## 📦 Installation & Usage

+## Known Limitations ##
+* Theoretically, a connection should be determined by a 5-tuple, but for most cases, connection mapping is currently based only on protocol type and source port.
+
+* In scenarios where proxying is based on process name, if a process starts a child process and uses execve to execute a new command, proxying will not work.
+
+* Since UDP network proxying is not yet supported, when using SOCKS5 proxy, please use Do53/TCP or ensure your SOCKS5 server supports server-side DNS resolution.

+# gotproxy
+
+简体中文 | [English](./README.md)
+
+这是一个简单的基于eBpf使用GO语言编写的透明代理程序，可以进行全局或者按照特定的ip,进程id,进程名称进行透明代理。
+该程序可以直接进行透明代理网络转发，支持socks5代理，可以替代redsocks,proxychains软件。也可以搭配其它代理软件或者L7层的代理实现分流，防火墙，MockServer的功能。
+
+## 📦 安装和使用
+
+**安装**
+
+直接在[release](https://github.com/Dream95/gotproxy/releases)中下载二进制文件
+
+***自行编译***
+1.  克隆git仓库:
+    ```bash
+    git clone https://github.com/Dream95/gotproxy.git
+    cd gotproxy
+    git submodule update --init --recursive
+    ./init_env.sh
+    ```
+2.  编译:
+    ```bash
+    make build-bpf && make
+    ```
+
+
+**使用**
+
+`gotproxy` 需要 root 权限才能运行.
+
+```bash
+sudo ./gotproxy [flags]
+```
+| Flag | 描述 |
+| :--- | :--- |
+| **--cmd** | 需要代理的进程名称. 如果没有配置，则会进行全局流量代理. |
+| **--pids** | 需要代理的进程id, 按照逗号进行分割. |
+| **--ip** | 需要代理的目标ip. |
+| **--p-pid** | 代理程序的进程id. 会自动过滤不代理该进程的网络通信，以免网络循环。如果没有配置, 本程序会自动启动一个转发代理服务. |
+| **--p-port** | 代理服务监听的端口。 |
+| **--socks5** | socks5代理的服务端地址，如果配置，会进行socks5代理. |
+
+
+正在开发中的功能：
+支持ipv6,支持udp
+
+
+
+***示例***
+1. 代理一个特定的进程名称的网络代理:
+
+```bash
+sudo ./gotproxy --cmd "curl"
+ ```
+
+2. 代理网络并进行socks5转发:
+
+```bash
+sudo ./gotproxy --socks5 192.168.1.2:1080
+ ```
+其中‘192.168.1.2:1080’是socks5代理服务器的ip和端口
+
+## 已知限制：
+* 理论上应该根据5元组确定一个连接，但是考虑大多数情况目前只根据协议类型和源端口进行连接映射。
+* 在根据进程名称进行代理的场景中，如果进程启动了子进程并使用了execve执行一个新命令，会无法进行代理。
+* 因为暂不支持udp的网络代理，因此在使用socks5代理时,请使用Do53/TCP,或者你的socks5服务端支持服务端DNS解析。
