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。

macOS Sierra (and possibly earlier) has some "hidden" screen sharing options:

If you're connecting to VNC using ssh tunneling, you can force macOS to listen only on localhost:

sudo defaults write /Library/Preferences/com.apple.RemoteManagement.plist VNCOnlyLocalConnections -bool yes

In newer versions of macOS, screen sharing will automatically re-lock the screen when you disconnect if it was locked when you first connected. To change this behavior, use:

sudo defaults write /Library/Preferences/com.apple.RemoteManagement RestoreMachineState -bool NO

# Try it if you have heavy load on server - network or memory / disk.
# No harm assumed but keep your eyes open.

# @updated: 2020-02-06 - more params used, adjust some params values, more comments on params
