Michael,
Thanks for your answer. My interface is completely 'up' after both
commands (promisc up and -promisc). But host computer and USRP2 can
only communicate when my network is in promiscuous mode.
I connect both, host computer and USRP2 through a direct connection
with a 1 Gb ethernet wire (n

Marcus,
I set permissions as you said:
/usr/bin$ sudo chmod 4775 usrp2_socket_opener
However it does not fix the problem. Only when setting my Ethernet
interface to promiscuous mode with:
sudo ifconfig eth0 promisc up
'find_usrps' does work perfectly.
If I execute
sudo ifconfig eth0

Are you certain that Network Manager is not interfering with the state
of your ethernet interface? The default config likes to enable and
disable the interface
Thanks for your quick answer. A problem with a firewall was an idea
that also came to my mind but I disabled the Ubuntu firewall with the
command "sudo ufw disable" so that no firewall is running into my
machine and the USRP2-Host computer connection is made directly with a
1 Gb ethernet wire.

I installed GNU Radio on a ThinkPad Lenovo T4410 under Ubuntu 10.04.
After connecting the USRP2 with the original Ettus code on the SD card D and
F LEDs are ok and when executed:
~$ sudo find_usrps
No USRP2 found.
I run wireshark or tcpdump to see what happens in my network and I got:
~$ sudo fi
