Debian双网卡配置

1.单网卡配置

/etc/network/interfaces

auto eth0
#iface eth0 inet dhcp（默认是DHCP被注释掉）
iface eth0 inet static
address 192.168.8.110
netmask 255.255.255.0
gateway 192.168.8.1

2.双网卡配置

/etc/network/interfaces

auto eth0
#iface eth0 inet dhcp（默认是DHCP被注释掉）
iface eth0 inet static
address 192.168.8.110
netmask 255.255.255.0
gateway 192.168.8.1

auto eth1
iface eth1 inet static
address 192.168.0.110
netmask 255.255.255.0
gateway 192.168.8.1

（注意eth1没有gateway ）

3.单网卡配置多ip

修改/etc/network/interfaces

auto eth0
iface eth0 inet static
address192.168.8.110
netmask 255.255.255.0
gateway 192.168.8.1

auto eth0:0
iface eth0:0 inet static
address 192.168.0.110
netmask 255.255.255.0

修改/etc/network/ifstate

lo=lo
eth0=eth0
eth0:0=eth0:0


如果没有/etc/network/ifstate，手工创建
/etc/init.d/networking restart
注意，eth0:0没有gateway，此方法测试有效
