Install "eapol_test" tool to test eduroam servers

Build the eapol_test tool on Rocky Linux 9 and use it to test authentication on an eduroam RADIUS server.

Updated 2026-11-12Sami Ait Ali Oulahcen

In order to verify that our eduroam SP (RADIUS) server correctly handles user authentication requests, we will install the `` eapol_test `` tool that can generate EAP requests similar to the users' and directly test the eduroam inner tunnel from the the command line interface (CLI). The tool should run on the same eduroam SP (RADIUS) server we want to test.
In this tutorial we will install and run eapol_test on Rocky Linux 9.

1. Download the source code#

wget https://w1.fi/releases/wpa_supplicant-2.11.tar.gz

Install dependencies:

dnf -y group install "Development Tools"
dnf -y install openssl-devel
dnf -y install libnl-3.0

Extract and build

tar -xvf wpa_supplicant-2.11.tar.gz
cd wpa_supplicant-2.11/wpa_supplicant
make eapol_test

Build a configuration file and run a test

Create the conf file poltest.conf.

vi poltest.conf

Paste the following content and modify according to your server's configuration.

network={
    ssid="eduroam"
    key_mgmt=WPA-EAP
    eap=TTLS
    phase2="auth=PAP"
    identity="edutest@uni.ma"
    password="edutest-secret-password"
}

Finally, run a test

./eapol_test -c poltest.conf -s testing123
