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 ?
