本小区上网是静态192.168.0.0/24网段上网的，链路提供商为广州电信，DNS为61.144.56.100。

    1.打开终端配置接口（也即网口）地址并保存！
    root@ns:/etc/network# vi /etc/network/interfaces
    iface eth0 inet static
    address 192.168.0.2
    netmask 255.255.255.0
    gateway 192.168.0.1

    #如果是动态DHCP获得更快，只需设置如下
    #auto eth0

    2.设置DNS服务器并保存！
    root@ns:/etc/network# vi /etc/resolv.conf
    nameserver 61.144.56.100

    3.重启网络，如下：
    root@ns:/etc/network# /etc/init.d/networking restart
    * Reconfiguring network interfaces… There is already a pid file /var/run/dhclient.eth1.pid with pid 5444
    killed old client process, removed PID file
