    朴素VPN：一个纯内核级静态隧道

由于路由管控系统的建立，实时动态黑洞路由已成为最有效的封锁手段，TCP连接重置和DNS污染成为次要手段，利用漏洞的穿墙方法已不再具有普遍意义。对此应对方法是多样化协议的VPN来抵抗识别。这里介绍一种太简单、有时很朴素的“穷人VPN”。
朴素VPN只需要一次内核配置（Linux内核），即可永久稳定运行，不需要任何用户态守护进程。所有流量转换和加密全部由内核完成，原生性能，开销几乎没有。静态配置，避免动态握手和参数协商产生指纹特征导致被识别。并且支持NAT，移动的内网用户可以使用此方法。支持广泛，基于L2TPv3标准，Linux内核3.2+都有支持，其他操作系统原则上也能支持。但有两个局限：需要root权限；一个隧道只支持一个用户。
朴素VPN利用UDP封装的静态L2TP隧道实现VPN，内核XFRM实现静态IPsec。实际上IP-in-IP隧道即可实现VPN，但是这种协议无法穿越NAT，因此必须利用UDP封装。内核3.18将支持Foo-over-UDP，在UDP里面直接封装IP，与静态的L2TP-over-UDP很类似。

    ##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

                This tutorial explains how to download videos from http://www.arte.tv/
              
          
    Edit 2021/02/16: warning

This gist is very old. I don't even know if it still works. Check the comments below to find more robust solutions, like youtube-dl for example, see this comment.
1

Go to http://www.arte.tv/ and select any videos, for example http://www.arte.tv/guide/fr/046618-011/silex-and-the-city
2

In the source code extract the src parameter of the iframe player:
http://www.arte.tv/player/v2/index.php?json_url=http%3A%2F%2Farte.tv%2Fpapi%2Ftvguide%2Fvideos%2Fstream%2Fplayer%2FF%2F046618-011_PLUS7-F%2FALL%2FALL.json&lang=fr_FR&config=arte_tvguide&rendering_place=http://www.arte.tv/guide/fr/046618-011/silex-and-the-city
