Centos VPS安装Pptp和OpenVpn的方法与经验分享: https://www.myzhenai.com.cn/post/871.html https://www.myzhenai.com/thread-15394-1-1.html
本来配置得好好的pptpd突然出现无法连接的故障，我以为是服务端出现了问题，还因此重装了VPS服务器，重新安装配置了Pptpd.后来找了另外一台windwos7 的机子发现可以正常连接，就是Centos里使用NetworkManager无法连接，这个问题折腾了两天，也删除过pptpd的连接重新设置也不济事，最后还是重新创建pptpd的连接解决了问题.
在pptpd编辑那里取消 “对所有用户可用”\ 先不要填写pptpd的连接密码 \ 其他配置请参考 “linux pptp客户端无法链接的解决方法”
然后连接重新创建的pptpd连接，在弹出的 “认证VPN”窗口中输入pptpd连接密码，并勾选“在密钥环中保存密码”
这样就解决问题了.
