これ、はてなの書き方ってどうやるの？
とりあえず以下のような感じでネットワークの設定。
$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.xxx.yyy
netmask 255.255.255.0
gateway 192.168.xxx.zzz
$
で
$ sudo /etc/init.d/networking restart
