# Fourth
|
||||
|
||||
> Hey, now we are on level 4!
|
||||
|
||||
[](https://crates.io/crates/fourth) [](https://github.com/KernelErr/fourth/actions/workflows/rust.yml)
|
||||
|
||||
**Under heavy development, version 0.1 may update frequently**
|
||||
|
||||
Fourth is a layer 4 proxy implemented by Rust to listen on specific ports and transfer TCP/KCP data to remote addresses(only TCP) according to configuration.
|
||||
|
||||
## Features
|
||||
|
||||
- Listen on specific port and proxy to local or remote port
|
||||
- SNI-based rule without terminating TLS connection
|
||||
- Allow KCP inbound(warning: untested)
|
||||
|
||||
## Installation
|
||||
|
||||
To gain best performance on your computer's architecture, please consider build the source code. First, you may need [Rust tool chain](https://rustup.rs/).
|
||||
|
||||
```bash
|
||||
$ cd fourth
|
||||
$ cargo build --release
|
||||
```
|
||||
|
||||
Binary file will be generated at `target/release/fourth`, or you can use `cargo install --path .` to install.
|
||||
|
||||
Or you can use Cargo to install Fourth:
|
||||
|
||||
```bash
|
||||
$ cargo install fourth
|
||||
```
|
||||
|
||||
Or you can download binary file form the Release page.
|
||||
|
||||
## Configuration
|
||||
|
||||
Fourth will read yaml format configuration file from `/etc/fourth/config.yaml`, and you can set custom path to environment variable `FOURTH_CONFIG`, here is an minimal viable example:
|
||||
|
||||
```yaml
|
||||
version: 1
|
||||
log: info
|
||||
|
||||
servers:
|
||||
proxy_server:
|
||||
listen:
|
||||
- "127.0.0.1:8081"
|
||||
default: remote
|
||||
|
||||
upstream:
|
||||
remote: "tcp://www.remote.example.com:8082" # proxy to remote address
|
||||
```
|
||||
|
||||
Built-in two upstreams: ban(terminate connection immediately), echo. For detailed configuration, check [this example](./example-config.yaml).
|
||||
|
||||
## Performance Benchmark
|
||||
|
||||
Tested on 4C2G server:
|
||||
|
||||
Use fourth to proxy to Nginx(QPS of direct connection: ~120000): ~70000 req/s (Command: `wrk -t200 -c1000 -d120s --latency http://proxy-server:8081`)
|
||||
|
||||
Use fourth to proxy to local iperf3: 8Gbps
|
||||

# Fourth
|
||||
|
||||
> 这一波在第四层。
|
||||
|
||||
[](https://crates.io/crates/fourth) [](https://github.com/KernelErr/fourth/actions/workflows/rust.yml)
|
||||
|
||||
[English](/README-EN.md)
|
||||
|
||||
**积极开发中，0.1版本迭代可能较快**
|
||||
|
||||
Fourth是一个Rust实现的Layer 4代理，用于监听指定端口TCP/KCP流量，并根据规则转发到指定目标（目前只支持TCP）。
|
||||
|
||||
## 功能
|
||||
|
||||
- 监听指定端口代理到本地或远端指定端口
|
||||
- 监听指定端口，通过TLS ClientHello消息中的SNI进行分流
|
||||
- 支持KCP入站（警告：未测试）
|
||||
|
||||
## 安装方法
|
||||
|
||||
为了确保获得您架构下的最佳性能，请考虑自行编译，首选需要确保您拥有[Rust工具链](https://rustup.rs/)。
|
||||
|
||||
```bash
|
||||
$ cd fourth
|
||||
$ cargo build --release
|
||||
```
|
||||
|
||||
将在`target/release/fourth`生成二进制文件，您也可以使用`cargo install --path . `来安装二进制文件。
|
||||
|
||||
或者您也可以使用Cargo直接安装：
|
||||
|
||||
```bash
|
||||
$ cargo install fourth
|
||||
```
|
||||
|
||||
或者您也可以直接从Release中下载二进制文件。
|
||||
|
||||
## 配置
|
||||
|
||||
Fourth使用yaml格式的配置文件，默认情况下会读取`/etc/fourth/config.yaml`，您也可以设置自定义路径到环境变量`FOURTH_CONFIG`，如下是一个最小有效配置：
|
||||
|
||||
```yaml
|
||||
version: 1
|
||||
log: info
|
||||
|
||||
servers:
|
||||
proxy_server:
|
||||
listen:
|
||||
- "127.0.0.1:8081"
|
||||
default: remote
|
||||
|
||||
upstream:
|
||||
remote: "tcp://www.remote.example.com:8082" # proxy to remote address
|
||||
```
|
||||
|
||||
内置两个的upstream：ban（立即中断连接）、echo（返回读到的数据）。更详细的配置可以参考[示例配置](./example-config.yaml)。
|
||||
|
||||
注意：[::]会默认同时绑定IPv4和IPv6。
|
||||
|
||||
## 性能测试
|
||||
|
||||
在4C2G的服务器上测试：
|
||||
|
||||
使用Fourth代理到Nginx（直连QPS 120000）: ~70000req/s （测试命令：`wrk -t200 -c1000 -d120s --latency http://proxy-server:8081 `）
|
||||
|
||||
使用Fourth代理到本地iperf3：8Gbps
|
||||
|
||||
## io_uring?
|
||||
|
||||
尽管经过了很多尝试，我们发现目前一些Rust下面的io_uring实现存在问题，我们使用的io_uring库实现尽管在吞吐量上可以做到单线程20Gbps（相比之下Tokio仅有8Gbps），但在QPS上存在性能损失较大的问题。因此在有成熟的io_uring实现之前，我们仍然选择epoll。之后我们会持续关注相关进展。
|
||||
|
||||
可能以后会为Linux高内核版本的用户提供可选的io_uring加速。
