You're using the "classic" API for the USRP2. Which has been obsolete for two years.
However, what seems to be going on here is that it can't find a device called "eth0" which is the default device that the "classic" API used to find USRP2s on. You'll also need to make sure that usrp2_socket_opener is setuid root. Another approach is to convert to UHD, burn UHD firmware into the USRP2, and use the "uhd_rx_cfile.py" program instead. -Marcus On Wed, 11 Apr 2012 17:18:26 +0100, [email protected] wrote: > I have recently installed GNU radio on my IBM lenovo machine (intel core i5) with fedora operating system.
