在Ubuntu 9.04 上安装PPTP的VPN服务

参考了很多文章终于在vpslink的Ubuntu 9.04下成功安装PPTP服务，并且iPad成功登录上网了。改下为我使用的步骤：

1、修改sources.list。

因为vpslink已经不维护mirror.vpslink.com了，所以我们需要自已定义一些public的mirror。

首先运行这个命令：

#sed -i 's/mirror.vpslink.com/mirrors.rit.edu/g' /etc/apt/sources.list

然后，修改/etc/apt/sources.list文件，替换成如下内容：

deb http://mirrors.163.com/ubuntu/ karmic main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ karmic-security main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ karmic-updates main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ karmic-proposed main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ karmic-backports main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ karmic main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ karmic-security main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ karmic-updates main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ karmic-proposed main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ karmic-backports main restricted universe multiverse
