redsocks升级记录

一直在用redsocks做流量转发,用着还是挺不错的,但是偶尔还是会hang住,导致网络卡住。老早就有升级的想法,一直没有动手。

什么是redsocks?

This tool allows you to redirect any TCP connection to SOCKS or HTTPS proxy using your firewall, so redirection may be system-wide or network-wide.

When is redsocks useful?

  • you want to route part of TCP traffic via OpenSSH DynamicForward Socks5 port using firewall policies. That was original redsocks development goal;
  • you use DVB ISP and this ISP provides internet connectivity with some special daemon that may be also called “Internet accelerator” and the accelerator acts as a proxy and has no “transparent proxy” feature and you need it. Globax was an example of alike accelerator, but Globax 5 has transparent proxy feature. That was the second redsocks` development goal;
  • you have to pass traffic through proxy due to corporate network limitation. That was never a goal for redsocks, but users have reported success with some proxy configurations.

以上是官方介绍。功能确实很强大,毕竟是俄国大佬的作品,继承了俄国产品强大而又粗糙的刻板印象。翻了他的repo,发现最后更新是2019年,而且还是改typo,其他的issue没有回复,大概大佬也不打算维护了吧。找了好久替代,发现了它的一个fork,似乎改了不少东西,就拖下来试试看吧。运行了一晚上,稳定性似乎还不错。

github地址 https://github.com/semigodking/redsocks

该repo依赖openssl和libevent2,libevent2在树莓派的repo中没有了,所以只能现编译。

现在把安装过程记录一下(仅限Raspberry Pi):

#安装openssl开发包

sudo apt install libssl-dev

#获取代码

wget https://github.com/libevent/libevent/releases/download/release-2.1.12-stable/libevent-2.1.12-stable.tar.gz

tar xvfz libevent-2.1.12-stable.tar.gz

cd libevent-2.1.12-stable

编译、安装

make
sudo make install

#克隆redsocks2的代码

git clone https://github.com/semigodking/redsocks

cd redsocks

make DISABLE_SHADOWSOCKS=1 ENABLE_STATIC=1

编译完,修改之前redsocks的配置文件、替换redsocks文件,重启服务即可。

目前暂时稳定。
