Introduction

For privacy/security reasons or in cases of limited network bandwidth/traffic, some people would like to control what connections Ubuntu automatically makes to the Internet. This article explains the reasons why Ubuntu makes this connections, and how you can stop it from doing so if you wish.

This list apply to Ubuntu 14.04 LTS.

Online search results in the Dash

  • Click the icon at the far right of the menu bar and select System Settings.
  • Open Security & Privacy and select the Search tab.

  • Switch off "Include online search results".
  • Log out and log back in for the change to take effect.

Apps Available for Download

gsettings set com.canonical.Unity.ApplicationsLens display-available-apps false

Time synchronization

By default, Ubuntu synchronizes the clock with ntp.ubuntu.com server on every boot. To disable:

  • Select the "Software & Updates" icon

  • Select the "Updates" tab
  • Select "Never" in "Automatically check for updates:"
