I am trying to get a GSM air interface set up running using USRP2, UHD, GNURadio. I have installed the latest UHD, using GNURadio 3.3.0. The OS is Ubuntu 10.04 LTS. I have installed UHD before GNURadio.
I have connected the USRP2 to a Gigabit Ethernet port of my PC at eth0. I am able to ping: address@hidden:/usr/local/bin# ping 192.168.10.2 PING 192.168.10.2 (192.168.10.2) 56(84) bytes of data. 64 bytes from 192.168.10.2: icmp_seq=1 ttl=32 time=1.08 ms

Then when I try to run uhd_find_devices, its all ok:
address@hidden:/usr/local/bin# uhd_find_devices linux; GNU C++ version 4.4.3; Boost_104000; UHD_003.001.002-unknown
But when I try running the usrp2_fft.py, I am not successful. address@hidden:/usr/local/bin# usrp2_fft.py Traceback (most recent call last):

I am not able to proceed further because of this. Kindly help.
