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.
