# 临时修改网卡地址 网关 Mac地址

1、临时性地修改MAC并设置静态IP(重启networking后设置复原) 首先，必须关闭网卡设备，否则会报告系统忙，无法更改：

 `sudo ifconfig dummy1 down` 

然后，修改MAC地址，填写修改后的MAC

 `sudo ifconfig dummy1 hw ether XX:XX:XX:XX:XX:XX` 

重新启用网卡

 `sudo ifconfig dummy1 up`

设置主机静态IP地址、子网掩码的操作： 

`sudo ifconfig dummy1 xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx` 

添加默认网关的操作： 

`sudo route add default gw xxx.xxx.xxx.xxx`
