eduroam for Linux

guide

This page describes how to connect your Linux or Ubuntu device to eduroam.

Before you configure your device, you must generate login credentials.

There are 3 methods to connect your device to eduroam:

EAP-PWD method (easy)
Manual configuration using EAP-PWD (advanced)
Manual configuration using EAP-PEAP (advanced)
Configuration using the Configuration Assistant Tool (CAT)

EAP-PWD method

The screenshots in this guide were made with Ubuntu 24.04.1.

Step 1
Click on the network icon to switch on the WLAN.

Step 2
Select eduroam from the list of available networks.

Step 3
Under Authentication, select PWD.

Step 4
Enter your eduroam login credentials under Username and Password.

Step 5
Click Connect.

Screenshot of the pop-up window with “PWD” in the drop-down menu. Instead of “Anonymous identity”, you will now find user name and password under Authentication. The user name ends with @rwth.edufi.de.

Your device is now connected to eduroam.

Manual configuration using EAP-PWD

You can also configure eduroam manually via EAP-PWD method.

Step 1
Create a configuration file under /etc/wpa_supplicant/wpa_supplicant.conf

Step 2
Copy the following settings in the file. Under Identity and Password enter your eduroam login credentials.

network={

ssid="eduroam"

key_mgmt=WPA-EAP

eap=PWD

identity="EGM_USERNAME@rwth.edufi.de"

password="CLEAR_TEXT_PASSWORD"

}

Note: It is not possible to use a certificate with the EAP-PWD method. If you want to use eduroam with a certificate, please use the EAP-PEAP method.

Manual configuration using EAP-PEAP

You can also configure eduroam manually via EAP-PEAP method.

Note: You will need an internet connection for this configuration. If you are currently at RWTH, you can use RWTH-guests.

Step 1
Download the security certificate under Certificate chain GÉANT/TCS.

Step 2
Create a configuration file under /etc/wpa_supplicant/wpa_supplicant.conf

Step 3
Copy the following settings to the file.

Under ca_cert, enter the name of the security certificate.
Under Identity and Password, enter your eduroam login credentials.

network={

ssid="eduroam"

key_mgmt=WPA-EAP

eap=PEAP

ca_cert="/etc/ssl/certs/Current_ROOT_CERT.pem"

phase2="auth=MSCHAPV2"

identity="EGM_USERNAME@rwth.edufi.de"

domain_suffix_match="radius.rz.rwth-aachen.de" # the option is only available for newer versions of wpa-supplicant,

# should match to the Radius-Realm or Radius-Server

subject_match="radius.rz.rwth-aachen.de" # for older versions is weaker than domain_suffix_match

# should match to the Radius-Realm or Radius-Server

anonymous_identity="anonymous@rwth.edufi.de"

password="CLEAR_TEXT_PASSWORD"

Configuration via the Configuration Assistant Tool (CAT)

Eduroam can also be set up on Linux using the Configuration Assistant Tool (CAT). We generally recommend connecting via the EAP-PWD method.

To set up eduroam on Linux using CAT, follow these steps:

Step 1
Visit the eduroam Configuration Assistant Tool (CAT) website on your device.

Step 2
Click the Click here to download your eduroam installer button.

Step 3

Step 4
Click the eduroam button. A file will be downloaded.

Step 5
Run the file in Python.

Step 6
Follow the installer prompts and enter the required information.

The installer will notify you when the process is complete.
