linux下网络接口参数配置

网络接口参数配置文件，下面是一个配置示例，它在一个网络接口中配置了两个静态IP地址：

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)# The loopback interfaceauto loiface lo inet loopback# The first network card - this entry was created during the Debian installation# (network, broadcast and gateway are optional)auto eth0iface eth0 inet static        address 192.168.1.1        netmask 255.255.255.0        network 192.168.1.0        broadcast 192.168.1.255#       gateway 192.168.1.1#       name 以太网局域网网卡auto eth0:0iface eth0:0 inet static        address 192.168.1.2        netmask 255.255.255.0        network 192.168.1.0        broadcast 192.168.1.255        gateway 192.168.1.1

下面是一个从DHCP服务器自动获得IP地址的示例：

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)# The loopback interfaceauto loiface lo inet loopback# The first network card - this entry was created during the Debian installation# (network, broadcast and gateway are optional)auto eth0iface eth0 inet dhcp
