This tutorial is applicable to Openv VPS, Xen VPS, or KVM VPS.

1. Run the following command:

cat /dev/net/tun

The returned value must be:

cat: /dev/net/tun: File descriptor in bad state

run:

cat /dev/ppp

The returned value must be:

cat: /dev/ppp: No such device or address

If the above does not return either of these two results, please contact VPS support to enable PPP and TUN permissions.
