Debian雙網卡配置

1.單網卡配置

/etc/network/interfaces

auto eth0
#iface eth0 inet dhcp（默認是DHCP被注釋掉）
iface eth0 inet static
address 192.168.8.110
netmask 255.255.255.0
gateway 192.168.8.1

2.雙網卡配置

/etc/network/interfaces

auto eth0
#iface eth0 inet dhcp（默認是DHCP被注釋掉）
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沒有gateway ）

3.單網卡配置多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


如果沒有/etc/network/ifstate，手工創建
/etc/init.d/networking restart
注意，eth0:0沒有gateway，此方法測試有效
