A simple script to set up policy routing on linux. It's stateless and detects everything automatically, so all you have to do is to run it after every network subsystem change. I run it in postup and postdown hooks in Gentoo network configuration file.

ss-redir 透明代理.md

##ss-redir 的 iptables 配置(透明代理)

透明代理指对客户端透明,客户端不需要进行任何设置就使用了网管设置的代理规则

创建 /etc/ss-redir.json 本地监听 7777 运行ss-redir -v -c /etc/ss-redir.json

iptables -t nat -N SHADOWSOCKS
# 在 nat 表中创建新链
iptables -t nat -A SHADOWSOCKS -p tcp --dport 23596 -j RETURN
# 23596 是 ss 代理服务器的端口,即远程 shadowsocks 服务器提供服务的端口,如果你有多个 ip 可用,但端口一致,就设置这个

Understanding the Pipes library

In response to this reddit post about failing to understand the Pipes library after a couple of hours. I wanted to show how an experienced haskeller does it, but I'm afraid it also took me quite a few hours, which is why the following list of steps goes on and on.

After all those hours, my opinion is that Pipes is not at all an easy library. I don't know if Conduit is any easier, but otherwise I side with your friend in advising to use something else (perhaps ordinary lazy IO?) instead of Pipes.

Anyway, here is the full brain dump of my steps as I tried to get your three snippets to fit together.

  • Since you say that you have a hard time combining the snippets, I assume that they must have complicated types. So my first goal is to figure out the type of your first snippet.
  • hoogle for parseUrl, withManager, etc. No results.
  • Google for haskell runEffect, find that it's a method from Pipes.Core,
