check configuration: # ifconfig eth0 eth0 Link encap:Ethernet HWaddr DC:41:A9:52:4E:6D inet addr:192.168.1.10 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::799f:e441:a0f6:8562/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:63262 errors:0 dropped:0 overruns:0 frame:0 TX packets:32456 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:111111111 (233.0 MiB) TX bytes:11111111 (139.0 MiB)
