Answer 1

You will need to set your DNS servers manually too. Example:

vi /etc/resolv.conf

Add the lines (based on opendns):

nameserver 208.67.222.222
nameserver 208.67.220.220

restart your networking:

service networking restart

Double check your IP, Netmask and gateway. They look ok on the surface but make sure nothing else on the network is using 192.168.1.100.

The section in your interfaces file should look similar to:

iface eth0 inet static
    address 192.168.1.100
    netmask 255.255.255.0
    gateway 192.168.1.1

Dont forget to restart your networking after every change!

Answer 2

Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

sudo gedit /etc/network/interfaces

Change:

iface eth0 inet dhcp 

To

iface eth0 inet static 

And add the following:

• address 10.0.1.100 (Ubuntu Server IP address)
• netmask 255.255.255.0
• gateway 10.0.1.1
• network 10.0.1.0
• broadcast 10.0.1.255
• dns-nameservers 10.0.1.1

You can also use Google’s Public DNS which is 8.8.8.8 or 8.8.4.4 for dns-nameservers.

Once done, restart networking

sudo /etc/init.d/networking restart
