在 ubuntu 14.04 上使用 cisco 兼容 vpnc
也尝试过这(不是相同的 vpn 客户端但尝试过)没有帮助...请帮忙...
并运行
$ sudo /usr/lib/NetworkManager/nm-vpnc-service --debug
对于调试我看到:

/usr/sbin/vpnc: noninteractive can't reuse password
** (nm-vpnc-service:21916): WARNING **: vpnc exited with error code 1
答案1
这通常意味着您输入了错误的密码(用户密码或组密码)。
提示是调试日志的最后一行:
/usr/sbin/vpnc: noninteractive can't reuse password
由于您通过网络管理器配置了 vpn,因此该vpnc
命令是非交互调用的,并且一旦检测到您提供的密码错误,它就无法要求输入新密码(因此“无法重复使用密码“ 信息)。
为了真正找到这一点,您可能需要检查调试的第一个块,您将能够看到:
Config: Debug 3
Config: Script /usr/lib/NetworkManager/nm-vpnc-service-vpnc-helper
Config: Cisco UDP Encapsulation Port 0
Config: Local Port 0
Config: IKE DH Group dh2
Config: Perfect Forward Secrecy server
Config: IPSec ID MY-VPN
Config: IPSec gateway AA.BB.CC.DD
Config: Xauth username USER
Config: Vendor cisco
Config: Enable Single DES
Config: NAT Traversal Mode natt
Config: Xauth password PASSWORD
Config: IPSec secret SECRET
最后两行包含明文用户密码和组共享机密。
我遇到了同样的问题,谷歌搜索到的第一个结果是https://mail.gnome.org/archives/networkmanager-list/2009-June/msg00034.html,因为第二个是这个问题,而且我确实在使用 ubuntu 14.04,所以我认为它可能会有所帮助。
