先用ifconfig
来查看所有活动网络接口
eth0 Link encap:Ethernet HWaddr b8:27:eb:1b:63:a8

设置IP和掩码
ifconfig eth0 192.168.1.6 netmask 255.255.255.0
设置网关
route add default gw 192.168.1.1
修改网卡MAC
ifconfig eth0 down
ifconfig eth0 hw ether b877c322f8
ifconfig eth0 up
设置DNS
vi /etc/resolv.conf
nameserver 114.114.114.114
nameserver 114.114.115.115
重启网络服务生效 service network restart
最新的ubuntu已经不能简单通过修改/etc/resolv.conf
来实现,需要修改resolvconf
配置文件,然后通过命令resolvconf
命令来操作
修改/etc/resolvconf/resolv.conf/
目录下的head文件
nameserver 114.114.114.114
然后通过更新配置来生效
resolvconf -u
