Internet beagleboneblack

Hi everyone,
I’m a french newbie on beagleboneblack, and I feel really hard to use it after the beaglebone original.

My first unsolved problem was setting up gpio in kernel (because the /sys/class/gpio files are useless if gpio are not set in mode7 and correct direction). So if you can tell me what I have to send by echo command in /pinmux-pins please tell me :’ ).

But that is not the topic, I must connect my board to internet to update my opkg and install .ik without dirty downloads.

I’m on fedora 19
I connect to beagle by ssh 192.169.7.2
An ifconfig on host gives me :

I’ve ever tryed lots of things founded on the web (like using .sh gived to setup ip following, etc …).

Please help me.
