as0t0：没有这样的文件或目录（errno = 2）

我只是尝试在使用OpenVZ的Debian VPS上安装OpenVPN Access Server。它安装很好，但是当我尝试从pipe理面板启动时，我得到这些错误：

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 process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t1: No such file or directory (errno=2)'] service failed to start or returned error status process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t2: No such file or directory (errno=2)'] service failed to start or returned error status process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t3: No such file or directory (errno=2)'] service failed to start or returned error status process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t4: No such file or directory (errno=2)'] service failed to start or returned error status process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t5: No such file or directory (errno=2)'] service failed to start or returned error status process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t6: No such file or directory (errno=2)'] service failed to start or returned error status process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t7: No such file or directory (errno=2)'] service failed to start or returned error status

有这个解决scheme吗？

尝试在OpenVZ上安装OpenVPN时，我遇到了类似的问题。你有很好的信息： http : //wiki.openvz.org/VPN_via_the_TUN/TAP_device

你的问题可能是：

tun模块不在HW节点上加载。如果您租用VPS，请向您的VPS提供商咨询tun-device。否则按照说明如何在HW节点上安装tun-module。
CT没有TUN / TAP设备的权利。按照上面的文档说明。
