linux network card configuration

DEVICE=物理设备名 
IPADDR=IP地址 
NETMASK=掩码值 
NETWORK=网络地址 
BROADCAST=广播地址 
GATEWAY=网关地址
TYPE=Ethernet (网络类型)
ONBOOT=[yes|no]（引导时是否激活设备） 
USERCTL=[yes|no]（非root用户是否可以控制该设备）
PEERDNS=[yes|no] (如果通过 DHCP 获取 IP ，是否将 DNS 信息写入 /etc/resolv.conf (覆盖))
BOOTPROTO=[none|static|bootp|dhcp]（引导时不使用协议|静态分配|BOOTP协议|DHCP协议） 
HWADDR = 你的MAC地址

Example:

/etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eth0
UUID=c5300c89-c3e4-4a3a-8344-5194975eacfb
DEVICE=eth0
ONBOOT=yes
IPADDR=192.168.1.170
PREFIX=24
#GATEWAY=192.168.1.79
IPADDR1=192.168.0.170
DNS1=114.114.114.114
DNS2=202.96.128.166

/etc/sysconfig/network-scripts/route-eth0：
default via 192.168.0.176 dev eth0
172.16.0.0/16 via 192.168.0.200 dev eth0
192.168.105.0/24 via 192.168.1.149 dev eth0
