在Debian(ubuntu就是Debian类linux)中网卡的设置可以通过/etc/network/interfaces文件来进行，具体可分为三种不同的配置方式：DHCP自动获取、静态分配IP地址和PPPoE宽带拨号。 

具体设置如下： 在进行配置之前，首先进入/etc/network目录中，编辑interfaces文件： 

网卡通过DHCP自动获取IP地址 

# 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（配置环回口） 
# 开机自动激lo接口 
auto lo 
# 配置lo接口为环回口 
iface lo inet loopback 
# 
# The primary network interface （配置主网络接口） 
#开机自动激活eth0接口 
auto eth0 
#配置eth0接口为DHCP自动获取 
iface eth0 inet dhcp

网卡静态分配IP地址 

# 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（配置环回口） 
# 开机自动激lo接口 
auto lo 
# 配置lo接口为环回口 
iface lo inet loopback 
# 
# The primary network interface （配置主网络接口） 
#开机自动激活eth0接口 
auto eth0 
#配置eth0接口为静态设置IP地址 
iface eth0 inet static 
address 10.16.3.99 
netmask 255.255.255.0 
network 10.16.3.0 
broadcast 10.16.3.255 
gateway 10.16.3.1 
# dns-* options are implemented by the resolvconf package, if installed（DNS设置） 
dns-nameservers 61.153.177.196 61.153.177.197

网卡进行PPPoE宽带拨号配置 

# 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（配置环回口） 
# 开机自动激lo接口 
auto lo 
# 配置lo接口为环回口 
iface lo inet loopback 
# 
# The primary network interface （配置主网络接口） 
#开机自动激活eth0接口 
auto eth0 
#配置eth0接口为静态设置IP地址 
iface eth0 inet static 
address 10.16.3.99 
netmask 255.255.255.0 
network 10.16.3.0 
broadcast 10.16.3.255 

配置完毕后，重启计算机或网络服务即可将网卡配好。重启网络服务命令为：

sudo /etc/init.d/networking restart
