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。
Php fpm is the new way to setup php to run with your webserver. Php-fpm is a fastcgi process manager for php that is totally separate from the webserver. The webserver communicates with fpm through a socket and passes the name of the script to execute. So fpm can run with any web server that is fastcgi compatible.
I recently moved from my old shared hosting to linode. Linode provides linux vps hosting at economic prices. However the servers are totally unmanaged are just raw linux machines that have shell access. So through the shell you have to setup everything including the web server, php and the web files.
So this time I decided to go with the combination of nginx and php-fpm. I had multiple sites to setup on this new webserver. Nginx deals with these through separate server blocks (aka vhost in apache). However there was another thing needed. Php on each site should run with its own user and not the nginx common user named www-data.
Running each site with its own uid/gid is more secure and
