尝试连接到 OpenVPN 时出现“Cannot ioctl TUNSETIFF tun：不允许操作”

  • 772

我正在尝试使用市场 AMI 在 AWS 中设置 OpenVPN 访问服务器，但我正在努力连接它。

访问服务器已启动并正在运行。我还添加了一个具有自动登录功能的用户并生成了相关的客户端配置和证书。

然后我将上述文件复制到我的机器上并尝试使用连接openvpn client.ovpn但得到以下输出和错误，

知道问题是什么吗？我认为由于 ERROR 行而无法创建隧道？

我正在运行服务器版本 2.0.10 和客户端版本，

  1. Best Answer

    看起来这是一个简单的 sudo 问题。

    sudo openvpn client.ovpn工作了一个款待。

  2. 创建 TUN 或 TAP 适配器需要您可能没有的权限 - 因此该命令适用于 sudo，但并非没有。

    在我的系统上，如果 openvpn 命令是这样运行的；

    sudo openvpn --config file.ovpn

    然后tun0创建一个设备。几乎总是，创建设备需要特权。

  3. 使用 Linux Mint，并通过网络管理器 UI（它不会提示输入 sudo pwd）进行连接——我认为没有必要。原来，这对我来说是个问题！从终端连接通过sudo完美。

  4. 您始终可以以 root 身份在 openvpn 二进制文件上运行 chmod u+s（设置 uid 0）。

    sudo chmod u+s $(哪个openvpn)

    这将允许本地用户以 root 用户身份执行该过程。此时，您的网络管理器/nm-applet 内容也将允许建立连接。
