your GPS Output means: "Got no fix", try it outdoors und clear sky
(the more sky visible, the better). If you're located in a city try it
on top of a flat building (don't ask me how to get there ;-)
Well, if you want to ping an IP your Moko needs an IP itself. Run a
dhcp-Client (udhcpc is installed):
> udhcpc eth0
If you're connected to the Internet and have DHCP enabled

should work now.
I recommend using wpa_supplicant to manage you WiFi while there is no
good GUI available, look at
Student of Computer Science at the University of Kaiserslautern.
