连接 PPTP VPN 时出现问题 - 调制解调器挂断

我在 Ubuntu 14.04 中连接 PPTP VPN 时遇到以下问题。

  1. 我安装了 ppp 和 ppp-linux

  2. 我将 /etc/ppp/chap-secrets 设置为以下内容

    113.41.242.167\\mark    PPTP    NaksOsP    *

  3. 我使用以下内容创建了 /etc/ppp/peers/vpn1

    pty "pptp 113.41.242.167 --nolaunchpppd"                                    
name 113.41.242.167\\mark                                
remotename PPTP                                
require-mppe-128                                
file /etc/ppp/options.pptp                                
ipparam vpn1                                
mru 1412                                
mtu 1412

  4. 我将 /etc/ppp/options.pptp 编辑为以下内容

    lock
noauth
refuse-pap
refuse-eap
refuse-chap
refuse-mschap-v2
nobsdcomp
nodeflate

  5. 然后我运行 sudo pon vpn1 但没有反应，所以我运行 sudo pon vpn1 debug dump logfd 2 nodetach 并得到以下输出

    pppd options in effect:

nodetach        # (from command line)

有人能帮我解决这个问题吗？我也试过网络管理器 GUI，但没有成功
