vpnc的VPN连接问题

Question

我能够通过VPN使用网络管理器-vpnc工作，没有任何问题，但突然停止工作。这是从我的syslog捕捉到的一个片段：

Sep  2 10:58:19 chachan-ThinkPad-L420 NetworkManager[1130]: <info> Starting VPN service 'vpnc'...

Sep  2 10:58:39 chachan-ThinkPad-L420 NetworkManager[1130]: <info> VPN service 'vpnc' disappeared

我试过重新启动、重新启动无线和重新启动网络。你知道我还能测试什么或者做什么吗？

提前感谢！

我似乎也有同样的问题。通过运行以下命令，我能够获得一些有用的调试输出：

sudo /usr/lib/NetworkManager/nm-vpnc-service --debug

出发地：https://wiki.gnome.org/NetworkManager/Debugging，然后在网络管理器中连接到vpn。不幸的是，让我用vpnc解决我的问题-连接工作略好于网络管理器-vpnc，使用思科VPN不工作上关于1des的说明，但并不能使它实际工作，因为我不知道如何处理调试输出，谈论ESP数据包。也许这个能帮到你。
