临时修改ip地址
ifconfig eth0 up //端口启用 ifconfig eth0 down //端口关闭 ifconfig eth0 192.168.1.10 //只修改ip地址 ifconfig eth0 192.168.1.10/24 或者 ifconfig eth0 1.1.1.1 netmask 255.0.0.0 //修改ip地址和掩码
临时修改网关
route //查看路由表 netstat -rn //查看路由表 route del default eth0 //删除eth0上的默认路由 route add default gw 192.168.1.1 //添加默认路由
永久修改ip地址和网关
