Configuring the OLPC XO Laptop for Home Wireless Network

Static IP Network

This section shows you how to get the OLPC XO onto a home wireless network where all of the wireless network clients uses static IP's. To get the OLPC XO onto such a network, the easiest method is to update the /etc/rc.local file with the correct configuration for your network. Place the following code into /etc/rc.local. Remember to replace each bracketed [] items with the correct network configuration information.

# home network

addNameServer ()
{
ip="$1"
file="/etc/resolv.conf"
result=`cat "${file}" | grep -c "${ip}"`

if [ ${result} -eq 0 ]
then
echo "nameserver ${ip}" >> "${file}"
fi
}

/etc/init.d/NetworkManager stop
/sbin/ifconfig eth0 [Static IP] up
/sbin/iwconfig eth0 mode managed
/sbin/iwconfig eth0 essid "[Wireless Network Name]"
/sbin/route add default gw [Gateway IP]
addNameServer "[DNS IP 1]"
addNameServer "[DNS IP 2]"

The /etc/rc.local file is executed every time you start up the OLPC XO. To return the XO to the original condition, just remove those lines. You can edit the /etc/rc.local file in the Terminal application, using this command (without double-quotes): "sudo nano /etc/rc.local"
