I cannot manage to load the tun module in my archlinux box. I'm trying to connect with openvpn, but the log says

nm-openvpn[6662]: Note: Cannot open TUN/TAP dev /dev/net/tun: No such device (errno=19)

lsmod | grep tun

returns nothing.

If I run

sudo modprobe tun

it returns failure, but no error message, and lsmod still has no tun. The module seems to exist, as there is a tun.ko.gz in /lib/modules/.......

I really dont know what else to try.

Thanks in advance
