这是一个自动安装脚本，for 大便系列。比如 大便和ubuntu（版权不是我的，我也只是拿来改改） ：

- #remove ppp pptpd
- rm -rf /etc/pptpd.conf
- rm -rf /etc/ppp
- apt-get -y remove ppp pptpd
- apt-get -y install ppp pptpd iptables
- #注意，这里的一些refuse-pap之类的要注意，如果不能连接首先改这里。
- #如果一直出错，将require-mschap-v2和require-mppe-128 这两行加密注释掉，（对应源文件）

第一次写和改。连参数都不会。将就点了。。嗯。上面的内容复制起来比较麻烦，所以我做一个文件，可以直接下载：
放到自己的目录下，chmod a+x 这个文件。再执行就OK了。
你可以先看一下这个文件。。。以防万一
