可在-u、-p后随意更改自己的登录用户名和密码。但密码长度必须大于8个 ASCII字符，否则为了安全，脚本将会随机生成密码。

注：

如果你无法访问一些特定网站，建议你修改ppp接口的MTU（很多时候能连接vpn但是无法打开某些网页也可能跟这个有关系）

输入vi /etc/ppp/ip-up

在倒数第二行加入如下内容：/sbin/ifconfig $1 mtu 1400

缺省 MTU:1496

保存后需要重启PPTP服务器，指令如下: systemctl restart pptpd

也可以不更改ip-up文件，而是在/etc/ppp/下新建ip-up.local文件。指令如下：

cat > /etc/ppp/ip-up.local << END
/sbin/ifconfig $1 mtu 1400
END
chmod +x /etc/ppp/ip-up.local

该脚本使用的是后者。
