I am using
NetworkManager to work with any kind of network connection.
Since I try to keep the system footprint small, I have not installed any gui for the NetworkManager.
Thanks to GallaFrancesco, I found a way to connect to my eduroam realm.
Execute the following command in your shell.
nmcli connection add \ type wifi con-name "eduroam" ifname $(ifconfig | grep -i w | cut -d":" -f 1) ssid "eduroam" -- \ wifi-sec.key-mgmt wpa-eap 802-1x.eap peap \ 802-1x.phase2-auth mschapv2 802-1x.identity "<username>@<realm>"
After that, restart your networkmanager service with
systemctl restart NetworkManager.service to ensure the eduroam connection was found.
nmtui and activate the
eduroam connection. Now, you have to provide your password.
I've created a small howto here.
