[Discuss-gnuradio] Destination Host Unreachable

[Brook Lin]

Hi ALL,

I am using Ubuntu 10.04 and installing the latest gnuradio download via git
clone http://gnuradio.org/git/gnuradio.git. To enable USRPN210+WBX, I also
follow the steps
(http://www.ettus.com/uhd_docs/manual/html/build.html#build-instructions-unix)
to build and install the UHD.  

However, before I load the firmware and image, it says "Destination Host
Unreachable" when "ifconfig eth0".

sudo ifconfig eth0 192.168.10.1
ping 192.168.10.2
PING 192.168.10.2 (192.168.10.2) 56(84) bytes of data.
>From 10.1.0.43 icmp_seq=1 Destination Host Unreachable
>From 10.1.0.43 icmp_seq=2 Destination Host Unreachable
>From 10.1.0.43 icmp_seq=3 Destination Host Unreachable

Hence, I cannot burn the firmware and fpga image. I also tried to disable
the firewall by sudo ufw disable, but it doesn't help. I also tried

sudo route add -net 192.168.10.0/24 dev eth1
sudo route -n

Can anyone give me any advice?

Thanks in advance,
Brook
