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。

Disable auto start for Android File Transfer
View disable-auto-android-file-transfer.md
  • Close Android File Transfer
  • Open Activity Monitor and kill “Android File Transfer Agent”
  • Go to where you installed “Android File Transfer.app” (I have it under /Applications)
  • Ctrl+click –> “Show package contents”
  • Go to Contents/Resources
  • Rename “Android File Transfer Agent” to e.g. “Android File Transfer Agent_DISABLED”
  • Then go to “/Users/username/Library/Application Support/Google/Android File Transfer” and again rename the Agent app.
