Eduroam – Linux: How to Verify Connection Type (Certificate or Username/Password-Based)

Follow the steps below to confirm whether your Linux device is using a certificate-based connection (EAP-TLS) or a username/password-based connection to the eduroam network.

1. From the command line interface (CLI), open/run the wpa_supplicant.conf file.
2. Review the configuration details. A sample configuration may look like the example below:

ssid="eduroam"
key_mgmt=WPA-EAP
eap=TLS
identity="test"
ca_cert="/home/pi/FreeRadiusCA.crt"
client_cert="/home/pi/test.crt"
private_key="/home/pi/test.key"
}

3. Check the eap value:

• If it shows TLS, the connection is certificate-based.
• If it lists a different type, run the eduroam installer and follow the instructions to import the certificate.
