Re: [Discuss-gnuradio] USRP2 connection problem

Hi Adrew,

I used wireshark instead of tcpdump and see something on the screen
but don't understand what they mean. As i read wireshark shows if we
send and receive packet to/from any device.But i see that i can send
and receive packets via eth0 by using ifconfig,

address@hidden:~$ sudo ifconfig eth0
[sudo] password for mehmet:
eth0      Link encap:Ethernet  HWaddr 60:eb:69:29:bb:c8
         inet6 addr: fe80::62eb:69ff:fe29:bbc8/64 Scope:Link
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
         RX packets:10416 errors:0 dropped:0 overruns:0 frame:0
         TX packets:2654 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:1000
         RX bytes:2112887 (2.1 MB)  TX bytes:324570 (324.5 KB)
         Interrupt:48 Base address:0x4000


Hi Eduardo,

I use HP pavilion dv6 core i7, and i checked the ethernet card it
supports the gigabit ethernet.

Do you have any other ideas why this could be happen?

Thanks a lot.

Mehmet.
