[Linux] 固定ip設定

1. 修改/etc/network/interfaces，僅留下以下資訊
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address  ip.ip.ip.ip
netmask 255.255.255.0
gateway ip.ip.ip.254
# dns-nameservers 10.110.15.1
# dns-nameservers 10.110.15.2

2. Ubuntu 12.04的dns改位置
舊版本修改/etc/resolv.conf
12.04需改在/etc/network/interfaces
dns-nameservers的部份
