连接 PPTP VPN 时出现问题 - 调制解调器挂断

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:
    debug       # (from command line)
    nodetach        # (from command line)
    logfd 2     # (from command line)
    dump        # (from command line)
    noauth      # (from /etc/ppp/options.pptp)
    refuse-pap      # (from /etc/ppp/options.pptp)
    refuse-chap     # (from /etc/ppp/options.pptp)
    refuse-mschap-v2        # (from /etc/ppp/options.pptp)
    refuse-eap      # (from /etc/ppp/options.pptp)
    name 113.41.242.167\\mark       # (from /etc/ppp/peers/vpn1)
    remotename PPTP     # (from /etc/ppp/peers/vpn1)
            # (from /etc/ppp/options.pptp)
    pty pptp 113.41.242.167 --nolaunchpppd      # (from /etc/ppp/peers/vpn1)
    crtscts     # (from /etc/ppp/options)
            # (from /etc/ppp/options)
    asyncmap 0      # (from /etc/ppp/options)
    mru 1412        # (from /etc/ppp/peers/vpn1)
    mtu 1412        # (from /etc/ppp/peers/vpn1)
    lcp-echo-failure 4      # (from /etc/ppp/options)
    lcp-echo-interval 30        # (from /etc/ppp/options)
    hide-password       # (from /etc/ppp/options)
    ipparam vpn1        # (from /etc/ppp/peers/vpn1)
    nobsdcomp       # (from /etc/ppp/options.pptp)
    nodeflate       # (from /etc/ppp/options.pptp)
    require-mppe-128        # (from /etc/ppp/peers/vpn1)
    noipx       # (from /etc/ppp/options)
    using channel 28
    Using interface ppp0
    Connect: ppp0 <--> /dev/pts/22
    sent [LCP ConfReq id=0x1 <mru 1412> <asyncmap 0x0> <magic 0xc953e228> <pcomp> <accomp>]
    sent [LCP ConfReq id=0x1 <mru 1412> <asyncmap 0x0> <magic 0xc953e228> <pcomp> <accomp>]
    Modem hangup
    Connection terminated.
    Script pptp 113.41.242.167 --nolaunchpppd finished (pid 8753), status = 0x0
    

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
