Re: [Discuss-gnuradio] UHD Announcement - April 23rd 2010

That does look a bit suspicious. I have two suggestions:

  1) if its a firewall issue, make sure that the linux firewall is off
  2) if its a timeout issue edit the udp_simple.cpp and change 
milliseconds(100) to something larger, say 1000
