How to make Tun module running at linux start

Question

i installed Tun using:

modprobe tun

then did:

lsmod | grep tun
tun                    83840  0

Please how to make Tun running at reboot?

This is written on Hamachi website:

...Then add tun to the list of modules by using your favorite text editor and Create /etc/modules-load.d/tun.conf 

#Load tun module at boot.
tun

But this folder foes not exist in my /etc

Is it wise to add line "modprobe tun" into /etc/rc.local ?

Why do you need it running at reboot? What tool are you using that isn't auto-loading it as needed? — Zoredache, Oct 24 '13 at 17:14
Some person requested it, and i assigned it to his virtual machine (openvz) — 16851556, Oct 25 '13 at 08:24
I assume you have seen this page? http://openvz.org/VPN_via_the_TUN/TAP_device. It has some suggestions — Zoredache, Oct 25 '13 at 15:24
You saw the line that said `To make sure that tun module will be automatically loaded on every reboot you can also add it or into /etc/modules.conf (on RHEL see /etc/sysconfig/modules/ directory`? Since you are using Centos the RHEL setting probably applies to you. — Zoredache, Oct 25 '13 at 21:50
in the /etc/sysconfig/modules im unsure what should be the filecontent to properly load Tun — 16851556, Oct 26 '13 at 11:07

Is there a file named /etc/modules ? If yes, you can edit to add tun there

Execute these 2 commands will create the rc.modules with command to load the tun module at startup

echo modprobe tun >> /etc/rc.modules
chmod +x /etc/rc.modules

no, it is not there, nor file, nor directory. There is no file modu* in /etc – 16851556 Oct 25 '13 at 08:23
What linux are you using? – Wutiphong Oct 25 '13 at 10:42

Check the link in my answer – Wutiphong Oct 26 '13 at 04:49
thx Wutiphong, i had no file /etc/rc.modules (only rc.local) so i executed that commands and now i see: lrwxrwxrwx - rc.local -> rc.d/rc.local ; -rwxr-xr-x - rc.modules ; is that correct? – 16851556 Oct 26 '13 at 09:12
You can execute 2 command in the edited answer. – Wutiphong Oct 26 '13 at 12:43
You need to change the module name after modprobe to tun – Wutiphong Oct 26 '13 at 13:58
thx, i did above commands so my rc.modules contains line: modprobe tun . but im unsure what you mean by changing the module name.. – 16851556 Oct 26 '13 at 14:08
In the example the module name is "foo" so I mean change it to tun – Wutiphong Oct 26 '13 at 14:24
