Thanks john, I will try out the commands you sent.
where can I download the newest build of the XS? I can't find it at
xs-dev.laptop.org or dev.laptop.org
We're hoping to get a working version of the XS by the end of this week.
Our pilot starts soon (April 13) and we want to get the XS working
sooner rather than later.
May I suggest bundling XFCE4 w/ the XS. I have installed it on my XS and
it eases working w/ wireshark and other aspects of testing. At least for
folks like myself that are less than expert w/ the command line.
thanks again for your help John
