1. 檔案內容

Debian網絡卡的配置檔案在/etc/network/interfaces中。

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback
 

2. 配置DHCP方式

auto eth0
iface eth0 inet dhcp

3. 配置靜態IP地址

auto eth0
iface eth0 inet static
address 192.168.1.10
netmask 255.255.255.0
# network 10.168.1.0
# broadcast 10.168.1.255
gateway 10.168.1.1

說明：auto eth0表示系統啟動網路時自動開啟相應的網路裝置
補充：當網絡卡多個IP

auto eth0:1
iface eth0:1 inet static
address 192.168.0.10
 

netmask 255.255.255.0
gateway 10.168.0.1

4. 配置DNS

檔案/etc/resolv.conf，新增：

nameserver 8.8.8.8

5. 重啟網絡卡

/etc/init.d/networking restart

6. 高階

/usr/share/doc/ifupdown/examples中例子使用mapping機制，可以使網絡卡在不同環境中自動切換IP地址。
