UBUNTU安装VPN PPTP一键安装包

wget http://www.lucong.com.cn/file/pptp-debian.sh && sh pptp-debian.sh
sh pptp-debian.sh

坐等安装，完后会给出默认用户名和密码。

随后软件自动配置vpn，在最后会给出默认的vpn用户名和密码，若要管理vpn用户，直接编辑/etc/ppp/chap-secrets文件对号入座即可，一行一个。

重启pptp后方可生效，/etc/init.d/pptpd restart

pptp-debian.sh内容如下：

#!/bin/bash

if [ $(id -u) != "0" ]; then

    printf "Error: You must be root to run this tool!\n"

    exit 1

fi
