problem with 4 way handshake over wired driver

[Javi Bustamante]

Hi,

I'm trying to perform WPA authentication over a wired ethernet using 
wpa_supplicant, hostapd and freeradius.
I'm using the EAP-TLS method. The EAP authentication goes ok, the 
wpa_supplicant receives a EAP-SUCCESS message. The authenticator receives 
the MS-MPPE-Send-Key and MS-MPPE-Recv-Key from the radius, but the problem 
is that the 4 way handshake doesn't start. ?Why does not the 4 way handshake 
start?

I have read that it is possible to integrate xsupplicant with wpa_supplicant 
using the -e option with the wpa_supplicant, but I can't find the -e option 
in the latest version (wpa_supplicant-0.4.7)

My configurations are this:

hostapd (ineteresting part):

driver=wired
auth_algs=1
ieee8021x=1
eap_server=0
auth_server_addr=127.0.0.1
wpa=2
wpa_key_mgmt=WPA-EAP


wpa_supplicant (interesting part):

eapol_version=1
ap_scan=0
network={
        proto=RSN
        key_mgmt=WPA-EAP
        pairwise=CCMP TKIP
        group=CCMP TKIP
        eap=TLS
        identity="javi"
        ca_cert="/etc/mycerts/root.pem"
        client_cert="/etc/mycerts/cliente.pem"
        private_key="/etc/mycerts/cliente.pem"
        private_key_passwd="whatever"
        psk="claveclave"
        priority=1
        eapol_flags=0
}


Thanks in advance,
Javi
