如何让此 Cisco VPN 客户端连接？

Question

我有 Ubuntu 10.10 64 位并安装了 network-manager-vpnc 并配置了连接，但我一直收到这个：

我在 Launchpad 上看到了几个错误，它们可能是同一件事，还是我做错了什么？

Answer 1

1. 安装vpnc 包：

   sudo apt-get install vpnc
   

2. 创建连接脚本，将下面的内容复制到一个名为 vpn-connect 的文件中，并将其放置在某个路径上：

   #!/bin/sh
   
   sudo vpnc --local-port 0 --enable-1des /etc/vpnc/vpn.conf
   

3. 复制 Windows Cisco VPN 客户端使用的 .pcf 文件，并将其用作步骤 4 的基础。

4. 现在您需要在 /etc/vpnc 目录中创建 vpn.conf 文件。该文件的内容如下：

   IPSec ID <your ipsec id>
   IPSec gateway <your gateway address>
   IPSec secret <your ipsec secret>
   
   Xauth username <your username>
   Xauth password <your password>
   IKE Authmode psk
   

   <your username>并且<your password>应该是显而易见的。

您现在拥有连接所需的一切，因此运行脚本：

vpn-connect

几秒钟后，它应该会返回以下消息：

VPNC started in background

并给你一个进程ID。

您现在应该已连接到 VPN。
