http://unix.stackexchange.com – 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. (HowTos)
