rinetd

rinetd

This is a golang version port of linux tool rinetd.

Feature

• config file each line is a listen chain
• each chain is a tcp listen or a udp listen
• support config file reload, file changed will apply for no need to exit app
• support comment, "//" "#" at line begin or comment at line end

Compile

go build -v

will generate rinetd executable file.

Use

Unlike the c version of rinetd, this rinetd use addr pairs writed in rinetd.conf.

The addr pairs format in rinetd.conf looks like

0.0.0.0:44444   127.0.0.1:55555     tcp
0.0.0.0:5679    127.0.0.1:8200      udp

first line represents rinetd will listen on 0.0.0.0:44444 for TCP, pipe read/write from this port to 127.0.0.1:55555.

second line represents rinetd will listen on 0.0.0.0:5679 for UDP, pipe read/write from this port to 127.0.0.1:8200.

You can also write commnet line begin with # or //.

WARN:The deny and allow not supported.

使用体验：配置文件描述太复杂了 单位面积有效信息量没当前 rinetd 配置的每行一个映射简单

而且也没有看到可以支持配置动态刷新功能。（v2 版本根本不支持全局配置文件，而是单个功能的配置文件， 单个功能的配置文件里可以进行 reload 功能开启）

使用体验：阅读代码发现代码没有我们优雅，没有增加 io.Copy Buffer大小，没有优雅关闭TCP单向通道。 没有UDP。rinetd可以转发UDP。
