Ubuntu 修改IP地址

1、ubuntu系统修改IP地址：sudo gedit /etc/network/interfaces

auto eth0

iface eth0 inet static

address 219.218.122.168

netmask 255.255.255.0

gateway 219.218.122.254

2、ubuntu系统修改DNS： sudo gedit /etc/resolv.conf

nameserver 202.194.15.12

3、使网络生效：sudo /etc/init.d/networking restart

Ubuntu8.04虚拟机更换host主机后开机无法加载网卡,提示:No such device

删除缓存文件，重启后解决。

sudo rm /etc/udev/rules.d/70-persistent-net.rules

reboot
