Linux configuration guide

Configuration guide for the SISSA Wired Network (dot1x authentication), using wpa_supplicant
This setting should be done only when a port authentication is required:

a) With your preferred text editor create the /etc/wpa_supplicant/SISSA-WIRED.wpa_supplicant.conf configuration file and insert the following lines:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
ap_scan=0

network={
        key_mgmt=IEEE8021X
        eap=PEAP
        phase2="auth=MSCHAPV2"
        identity="yourusername"
        password="yourpassword"
        eapol_flags=0
}

Insert your yourusername and yourpassword (the same of your SISSA webmail) in the identity and password fields.

b) Dependig on your distribution you have to continue in different ways.
If you click on your laptop OS distribution name in the following lines,
you will be “placed” at the beginning of specific instruction.

Generic Linux distribution
Ubuntu/Debian based distributions
Fedora/RedHat distributions

GL-a) Run the following command in order to activate the wpa_supplicant daemon:
