Step 1. You will need to find the following info about the network
1. Available IP Address
2. Network Netmask
3. Broadcast IP
4. Default Gateway
Step 2. Open /etc/network/interfaces:
$ sudo vim /etc/network/interfaces
Once there, we must find the network interface to be configured from a dynamic IP address to a static one. In this case it will be eth0:
auto eth0
iface eth0 inet dhcp
In the above example we can see that the interface eth0 is configured for dhcp (dynamic address). To change to static IP address configuration we must set the following:
auto eth0
iface eth0 inet static
address 192.168.1.2
netmask 255.255.255.0
nerwork 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.254
Finally, we need to restart the networking services:
$ sudo /etc/init.d/networking restart
Set OpenDNS as your DNS server
Step 1. Open the resolv.conf file
sudo vim /etc/resolv.conf
Once Open comment out whatever name server is already there. More than likely these are DNS Servers provided to you by your ISP, and are thus worthless. After commenting out the old DNS server address, append the following two lines of text.
nameserver 208.67.222.222
nameserver 208.67.220.220
Now just save and quit, you are done.
