我正在尝试连接到 vpnc vpn。
/etc/vpnc/clientvpn.conf我首先创建了一个如下所示的conf 文件：
## generated by pcf2vpnc
IPSec ID mygroupid
IPSec gateway some.ip.add.ress
IPSec secret mygrouppassword
Xauth username myusername
Xauth password myuserpassword
IKE Authmode psk
并且使用sudo vpnc clientvpn效果很好。
现在我想使用 network-manager vpnc 插件。我创建了一个新的 vpn 设置，并设置了不同的值：
我保留了高级设置的默认值。尝试从 NetworkManager 连接失败，并显示以下日志：
NetworkManager[1155]: <info> Starting VPN service 'vpnc'...

我不确定这是否/sys/devices/virtual/net/tun0: couldn't determine device driver; ignoring...是一条有意义的信息。
为什么插件运行正常nm但是却失败了？vpnc
