WPA supplicant

To use wpa_supplicant, you need to setup the configuration, start the daemon, and use the wpa_cli.

Edit /etc/wpa_supplicant/wpa_supplicant.conf:

ctrl_interface=/run/wpa_supplicant
update_config=1
country=IT

network={
     ssid="eduroam"
     scan_ssid=1
     key_mgmt=WPA-EAP
     eap=PEAP
     phase1="peapver0"
     phase2="auth=MSCHAPV2"
     identity="name.surname@unitn.it"
     passwprd="my_password"
     ca_cert="/etc/ssl/certs/ca-certificates.crt"
     ieee80211w=0
     domain_suffix_match="unitn.it"
}

Edit /etc/network/interfaces

allow-hotplug wlan0
iface wlan0 inet dhcp
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

Run the daemon:

wpa_supplicant -d -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant-eduroam.conf

Use wpa_cli:

wpa_cli
> status
> list_networks
> select_network 0

This should be enough to connect to the internet. If you have a container or virtual machine, you may have to do additional steps like:

iptables -t nat -A POSTROUTING -s '192.168.100.0/24' -o wlan0 -j MASQUERADE

or adding a nameserver in /etc/resolv.conf
