set a openDNS for linux ubuntu 14.04

noting to say, always the following commands:

(1)modify head

sudo gedit /etc/resolvconf/resolv.conf.d/head

then add the follow addresses:

<span style="font-size:24px;">nameserver 208.67.222.222
nameserver 208.67.220.220
nameserver 114.114.114.114
nameserver 8.8.8.8
nameserver 8.8.4.4</span>

(2)modify resolv.conf. (in the past, I only modify the file resolv.conf, but after a shutdown, it changes to the original. Then I know that the file "resolv.conf" is loaded from head, so modifing the file "head" is important! )

<span style="font-size:24px;">sudo gedit /etc/resolv.conf</span>

then add the same contest:

<span style="font-size:24px;">nameserver 208.67.222.222
nameserver 208.67.220.220
nameserver 114.114.114.114
nameserver 8.8.8.8
nameserver 8.8.4.4</span>

(3)restart the service

<span style="font-size:24px;">sudo /etc/init.d/networking restart</span>

(4)two DNS test websites, they can test your DSN service address.
