Setting up eduroam: Linux

How to connect to eduroam using the CAT installer on Linux

Note: These instructions are for configuring eduroam for Ubuntu 18.04 LTS (Bionic Beaver). The screen layouts, settings and steps might be different for other versions of Ubuntu and alternative Linux.

These instructions make use of a python script provided via the eduroam Configuration Assistant Tool (CAT) website. Information about how the script works is available during the download process. The script should work with Python 2.7 or Python 3. If these instructions do not work for you then you should use the generic settings to make your connection.

Before you begin, make sure you:

  • are in a location where the eduroam wireless network is available
  • have your @cam email address handy
  • have collected your network access token from the UIS token page.

Download the eduroam CAT installer:

  • In a web browser, go to cat.eduroam.org (opens a new browser window).
  • Click the 'download your eduroam installer' button.
  • A pop-up window will appear listing nearby profiles, check that 'United Kingdom' is selected next to 'Show organisations in' at the bottom of this window.

  • If 'University of Cambridge' is not listed then search for it using the search box at the bottom of the list.
  • Select 'University of Cambridge'.
  • You will now see two clickable boxes - 'Download your eduroam installer Linux' and an information box 'i'. If you would like more information about how the script works click on 'i'.

Run the installer to configure your connection

  • Open a terminal window ('ctrl-alt-t' should work on most platforms).
  • Go to the directory that the installer was downloaded to (e.g. 'cd ~/Downloads').
  • Run the installer by typing 'python eduroam-linux-UoC-eduroam.py'.
  • An information pop-up should appear, click 'OK'.

  • Select the 'Settings' icon Linux eduroam settings icon screenshot.
  • Choose Wi-Fi from the top of the list on the left.
  • If 'Wi-Fi' is currently turned off, turn it on using the slider at the top of this window.
