My Pi stopped connecting to the internet by ethernet

Question

I installed Rasbian Jessie Lite on my Raspberry Pi Zero a few hours ago.

I hooked up a multi-usb hub to the Zero. The hub has an ethernet port, where I connected my modem.

I ran apt-get install for:

• xorg

• mate-desktop-environment-core

• wicd (internet network manager I like)

• epiphany-browser

I could browse the internet just fine for a while, but now I can't connect. wget http://google.com tells me the host could not be resolved.

When I open Wicd while connected straight to my modem, I see the wired network as an option. I click "Connect," everything seems to run, but the Zero just does not connect.

Here's my output from wicd.log on my most recent connection attempt:

Answer 1

I bet your DNS resolvers aren't configured. This is a common issue in Linux.

Add nameservers in the /etc/resolv.conf file by adding the lines below:

nameserver 208.67.222.222
nameserver 8.8.8.8

These lines add OpenDNS' nameserver (first line) and Google's DNS server (2nd line)

Alternatively, you could add the DNS servers in the GUI network manager by clicking "Properties" under the connection then setting Static DNS to the IP addresses provided.
