There are lots of questions pertaining this error, and there is a suggested manual fix which works well, but there’s no permanent solution. How can i permanently solve this? Im having this issue on a debian wheezy server, using OpenVPN client to connect to an OpenVPN server.
The suggested fix is the one below. Seems like, /dev/net is not automatically created and of course disappears on each reboot.
mkdir -p /dev/net mknod /dev/net/tun c 10 200 chmod 600 /dev/net/tun
