Usage: ./CentOS7-pptp-host1plus.sh [OPTION]
If you are using custom password , Make sure its more than 8 characters. Otherwise it will generate random password for you. 
If you trying set password only. It will generate Default user with Random password. 
example: ./CentOS7-pptp-host1plus.sh -u myusr -p mypass
Use without parameter [ ./CentOS7-pptp-host1plus.sh ] to use default username and Random password
  -u,    --username             Enter the Username
  -p,    --password             Enter the Password

一键脚本

  1. wget http://files.cnblogs.com/files/wangbin/vpn_centos.sh
  2. chmod +x ./vpn_centos.sh
  3. ./vpn_centos.sh

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
