i have got a virtual private server with Ubuntu 12.04.2 LTS (GNU/Linux 2.6.32-5-openvz-amd64 x86_64). I want to install openvpn but this requires a working tun device. i get the following error:
Note: Cannot open TUN/TAP dev /dev/net/tun: Operation not permitted (errno=1)
# modprobe tun
WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/.
FATAL: Module tun not found.
What do i have to do to get this tun running?
I think you will have to ask your VPS provider to enable TUN/TAP. If they won't enable TUN/TAP you can't use openvpn.
