我刚刚尝试在使用 OpenVZ 的 Debian VPS 上安装 OpenVPN Access Server。它安装得很好，但是当我尝试从管理面板启动它时，出现了以下错误：
process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t0: No such file or directory (errno=2)']
service failed to start or returned error status

有解决办法吗？

我在尝试在 OpenVZ 上安装 OpenVPN 时遇到了类似的问题。您可以在以下位置找到有用的信息：http://wiki.openvz.org/VPN_via_the_TUN/TAP_device
你的问题可能是：
- HW-node 上未加载 tun 模块。如果您租用 VPS，请向您的 VPS 提供商索要 tun 设备。否则，请按照说明在 HW-node 上安装 tun 模块。
- CT 没有 TUN/TAP 设备的权限。请按照上述文档中的说明进行操作。
