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

Generate /etc/hosts with Ansible
# Idempotent way to build a /etc/hosts file with Ansible using your Ansible hosts inventory for a source.
# Will include all hosts the playbook is run on.
# Inspired from http://xmeblog.blogspot.com/2013/06/ansible-dynamicaly-update-etchosts.html
- name: "Build hosts file"
lineinfile: dest=/etc/hosts regexp='.*{{ item }}$' line="{{ hostvars[item].ansible_default_ipv4.address }} {{item}}" state=present
when: hostvars[item].ansible_default_ipv4.address is defined
with_items: groups['all']

测试平台:DigitalOcean VPS ubuntu14.04 x64, strongswan5.2.2

运行以下命令请使用root权限

一:安装strongswan

由于ubuntu软件仓库中strongswan版本较低,因此从官网源码编译安装

apt-get install build-essential     #编译环境
aptitude install libgmp10 libgmp3-dev libssl-dev pkg-config libpcsclite-dev libpam0g-dev     #编译所需要的软件

在OpenWrt上配置redsocks2

redsocks2是一款透明socks5代理工具,能够实现智能代理的功能,这里是redsocks2在OpenWrt上的配置,配合shadowsocks使用。

redsocks.conf 是配置文件,放在/etc目录,将192.168.1.1改成路由器的地址. redsocks2.sh 为自启动文件,改名为redsocks2放到/etc/init.d目录即可。自启动文件假设redsocks可执行文件在/opt/bin目录。

启动redsocks2: /etc/init.d/redsocks2 start 停止redsocks2: /etc/init.d/redsocks2 stop

module: copy_remotely
short_description: Copies a file from the remote server to the remote server.
description:
- Copies a file but, unlike the M(file) module, the copy is performed on the
remote server.
The copy is only performed if the source and destination files are different
(different MD5 sums) or if the destination file does not exist.
