OpenVPN是一个用于创建虚拟专用网络加密通道的软件包，最早由James Yonan编写。

OpenVPN is a free and open source virtual private network (VPN) program for creating point-to-point or server-to-multiclient encrypted tunnels between host computers. It is capable of establishing direct links between computers across network address translators (NATs) and firewalls. It was written by James Yonan and is published under the GNU General Public License (GPL).

以前写过一篇文章《OpenVPN server install and config the bridge on Fedora 10》，不过因为内部使用，没有试过用户名/口令认证，现在需要研究一下。

为什么不用pptp而选择openvpn的原因：“来自@LEMONed的消息，只有Xen的VPS可以搭建pptp，OpenVZ的不行。”
