Я пытаюсь настроить сеть MIPS Linux. Вот его конфигурация:
~ # ifconfig
eth0 Link encap:Ethernet HWaddr CC:5D:4E:FF:45:7F
inet addr:192.168.0.2 Bcast:192.168.0.255 Mask:255.255.255.0

Могу пинговать интернет-ресурсы по IP-суммам:
~ # ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
64 bytes from 8.8.8.8: seq=0 ttl=44 time=60.757 ms
^C
--- 8.8.8.8 ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max = 60.757/60.757/60.757 ms
Но DNS не работает:
~ # ping google.com
ping: bad address 'google.com'
И даже локальные HTTP-ресурсы недоступны:
~ # wget http://192.168.0.1/
Connecting to 192.168.0.1 (192.168.0.1:80)
wget: can't connect to remote host (192.168.0.1): Connection timed out
TCP-соединения зависают в состоянии SYN_RECV / SYN_SENT:
~ # netstat -n
Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address Foreign Address State

Что может быть не так? Спасибо.
