Hi Victor,
this looks like a network malconfiguration.
With redhat/fedora-based Distributions usually a rather restrictive
firewall is shipped, disabling a range of types of broadcast traffic.
The issue is described at
http://files.ettus.com/uhd_docs/manual/html/usrp2.html#firewall-issues ;
use the firewall administration utility to change the settings accordingly.
Greetings,
Marcus M

Hello, I'm new to using GNURadio and the USRP.
I'm running Fedora 17 with GNURadio (3.5.3.1) and UHD (3.4.3)
installed with yum.
I'm trying to run uhd_fft.py and I get the following error:
$ ./uhd_fft.py
linux; GNU C++ version 4.7.0 20120507 (Red Hat 4.7.0-5); Boost_104800;

I'm wondering if there is a mismatch on my UHD driver and the
firmware/fpga images?
Because when I do:
$ uhd_find_devices
linux; GNU C++ version 4.7.0 20120507 (Red Hat 4.7.0-5); Boost_104800;
UHD_003.004.003-0-unknown
No UHD Devices Found
BUT:
$ uhd_find_devices --args="addr=192.168.10.2"
linux; GNU C++ version 4.7.0 20120507 (Red Hat 4.7.0-5); Boost_104800;
UHD_003.004.003-0-unknown
--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
type: usrp2
addr: 192.168.10.2
name:
serial: E0R22N8UP
A similar thing happens when I run 'uhd_usrp_probe' ... if I do not
specify the address then nothing is found, but if I supply the IP
address then it prints out information that looks good.
I can ping 192.168.10.2 successfully as well.
Any ideas?
Thanks
