Whenever I hear of anyone struggling with ethernet ports going up and down unexpectedly on Ubuntu it nearly always comes down to Ubuntu's Network Manager trying to be clever. Go google information on how to disable Ubuntu from automatically managing network interfaces for the version you are using, then ifconfig will likely do what you expect it to.
As far as GPSDO not being found, it takes time for GPS's to achieve a lock after a power cycle event, easily on the order of seconds. The USRP is just parsing ASCII string output from the GPS on a UART. I doubt this is indicative of any type of real problem in your case. Note also that GPSDO's need to be powered up for many minutes before they have a stable clock that meets there specified performance. -Ian On Nov 30, 2013, at 5:56 AM, Nasi <nesaz...@mail.ru> wrote: > Dear All, > > my device: USRP N200 > System: Ubuntu 13.04 > > 1.
