Are you directly connected to your PC? What kind of network card do you  
have?

Jay mentioned in a previous email ubluntu 11.10, which is quite old by  
now (13.04 is out). Perhaps there could be a network driver issue that  
was resolved in a newer release.

I’m also getting that error about 50% of the time when running through a

icmp port unreachable msg to the usrp.
