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,
meh...@mehmet-pc:~$ 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.
