[Roboticsprimer-users] Dialog?

[Robotics P. u. h. l. <rob...@li...>]

I messed about with some ping and some net commands and now both gumstix and my development computer see each other and send messages. See the following dialog.
The Gui comes up for a second or two and then intro crashes

On Gumstix 
# ./player roomba.cfg

If I dont plug gumstix into I create player immediately crashes. So I think I have, at least minimal, communications from build computer to gumstix to iCreate  and from 
gumstix back to build computer.

Questions
1) Does my analysis seem consistent with your  experience?
2) How do I go about debuging the connection?
3)Is there some documentation  for the error messages?
4)any suggestions of where to go from here?
