Qt Embedded on Pandaboard with ethernet

Hey,

I have this GUI application with a UDP communication backend which i want to run on my Pandaboard. I have cross compiled the Qt for Embedded library and have the application running using the virtual frame buffer. The user interface works fine no issues there. But I see that the primary functionality of the UDP communication that I have written is not working. Packets are not getting sent at all from the application. (This functionality has been tested and verified on my x86 development system). I installed Wireshark on the board and tried capturing and i see there are no packets associated with the application. Is there anything I am missing here ?

Any sort of help will be highly appreciated :)

Thanks a lot,
