Ubuntu 14.04用配置文件配置静态IP和动态IP

1，静态IP：

# cat /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)

auto lo

iface lo inet loopback

auto eth0

iface eth0 inet static

address 219.224.167.193

gateway 219.224.167.129

netmask 255.255.255.0

broadcast 219.224.167.255

=============================

2，动态IP：

# cat /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)

auto lo

iface lo inet loopback

auto eth0

iface eth0 inet dhcp
