Usrp2 not connecting to laptop via ethernet cable

GNU Radio
1

I have recently installed GNU radio on my IBM lenovo machine (intel core
i5) with fedora operating system. I am using usrp2 with Ethernet cable.
| wanted to connect the laptop with usrp2 but the laptop does not detect
the usrp2 box. the icon says connecting rather than connected.

I tried to test it with my program but i receive the following error.

[root@localhost TV_sensing_1.3]# python usrp2_rx_cfile_03.py -v -d 6 -f
714M -N100000 /home/umer/umer_GNU/TV_sensing_1.3/${freq}.bin;
eth0: SIOCGIFINDEX: No such device
Traceback (most recent call last):
File “usrp2_rx_cfile_03.py”, line 142, in
tb = rx_cfile_block(options, filename)
File “usrp2_rx_cfile_03.py”, line 47, in init
self._u = usrp2.source_32fc(options.interface, options.mac_addr)
File “/usr/lib/python2.7/site-packages/gnuradio/usrp2.py”, line 679,

return _usrp2.source_32fc(ifc, mac)

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.
