Ubuntu server cannot access internet, however can use SSH

Question

So as stated I can access my server remotely, and locally using SSH, however I dont have access to "The internet". By this I mean I cant access webpages.

dtipp@mc-server:~$ ping www.google.com
ping: unknown host www.google.com

That is what I get when I try to ping google.

dtipp@mc-server:~$ curl -s checkip.dyndns.org | sed -e 's/.*Current IP Address: //' -e 's/<.*$//'  

Doesn't yield an ip address like it used to. All my problems started after trying to setup a static ip address. I finally managed to get my file to look like I thought it was supposed to, but only just now have the issues started.

dtipp@mc-server:~$ ifconfig

This is the setup file, and the results of a few other ping things. Have I done something wrong or do I need to be doing something additional?

When you set a static IP address, you must also set DNS nameservers.I suggest you amend /etc/network/interfaces to:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
    address 192.168.1.120
    netmask 255.255.255.0
    gateway 192.168.1.1
    dns-nameservers 192.168.1.1 8.8.8.8

Restart the interface:

sudo ifdown eth0 && sudo ifup -v eth0

Test:

ping -c3 www.ubuntu.com

Your /etc/resolv.conf is also incorrect. Please amend:

nameserver 127.0.1.1
