TUN/TAP ( VPN Module ) on openVZ VPS
openVZ supports Tun/TAP in a container through kernel TUN/TAP module. In order to allow for e.g. #9, following is the procedure :
Please make sure you have tun module already on the main hardware node :
================
lsmod | grep tun
================
In case it is not there, you may command the following :
============
modprobe tun
============
Or rather you may also add it to /etc/modules.conf in order to load next time you reboot.
Therefter, in order to allow Access to TUN/TAP :
vzctl set 9 –devices c:10:200:rw –save
vzctl set 9 –capability net_admin:on –save
Then, you may create a character device file within the container :
========================================
vzctl exec 9 mkdir -p /dev/net
vzctl exec 9 mknod /dev/net/tun c 10 200
vzctl exec 9 chmod 600 /dev/net/tun
========================================
You have now enabled TUN/TAP on your VPS Hosting package.
