Hi, I am trying to configure Fast Transition between 2 AccessPoints. I was able to get working config for FT-PSK with local key generation (ft_psk_generate_local=1) However, for FT-EAP its not an option. So I set following configuration: AP-1 #MAC Addresses used #wlan0 ether 30:b5:c2:15:73:1c txqueuelen 1000 (Ethernet) #wlan1 ether 30:b5:c2:15:da:b2 txqueuelen 1000 (Ethernet) #wlan2 ether 30:b5:c2:18:b3:34 txqueuelen 1000 (Ethernet) #----------------------------------------------------------------------------- interface=wlan0 logger_syslog=-1 logger_syslog_level=2 logger_stdout=-1 logger_stdout_level=2 ctrl_interface=/var/run/hostapd eapol_key_index_workaround=0 eap_server=1 eap_user_file=/opt/eap/peap-alpha/hostapd.eap_user ca_cert=/opt/eap/peap-alpha/CA.crt server_cert=/opt/eap/peap-alpha/CA.crt private_key=/opt/eap/peap-alpha/CA.key ieee8021x=1 wpa=2 #changes for 802.11r: #only FT-clients: wpa_key_mgmt=FT-EAP #push R1 key to other APs: pmk_r1_push=1 #list of keyholders, AES-128 keys: openet1, openet2: r0kh=30:b5:c2:15:da:b2 ap2.example.com 1FC4BBA69DB8EB396A24249B406BA2A5 r0kh=30:b5:c2:15:73:1c ap1.example.com 1FC4BBA69DB8EB396A24249B406BA2A5 r1kh=30:b5:c2:15:73:1c 30:b5:c2:15:da:b2 1FC4BBA69DB8EB396A24249B406BA2A5 r1kh=30:b5:c2:15:da:b2 30:b5:c2:15:73:1c 1FC4BBA69DB8EB396A24249B406BA2A5 #NAS ID: nas_identifier=ap1.example.com #mobility domain: mobility_domain=a1b2 #interface to send/receive packets r0_key_lifetime=10000 ft_over_ds=0 r1_key_holder=30b5c215731c ft_psk_generate_local=1 #reassociation deadline in time units (TUs / 1.024 ms; range 1000..65535) reassociation_deadline=1000 wpa_pairwise=CCMP wpa_group_rekey=3600 rsn_pairwise=CCMP rsn_preauth=0 ctrl_interface_group=0 macaddr_acl=0 ssid=802.11R_AP country_code=IE ieee80211n=1 ieee80211d=1 hw_mode=g channel=7 AP-2 #MAC Addresses used #wlan0 ether 30:b5:c2:15:73:1c txqueuelen 1000 (Ethernet) #wlan1 ether 30:b5:c2:15:da:b2 txqueuelen 1000 (Ethernet) #wlan2 ether 30:b5:c2:18:b3:34 txqueuelen 1000 (Ethernet) #----------------------------------------------------------------------------- interface=wlan0 logger_syslog=-1 logger_syslog_level=2 logger_stdout=-1 logger_stdout_level=2 ctrl_interface=/var/run/hostapd eapol_key_index_workaround=0 eap_server=1 eap_user_file=/opt/eap/peap-alpha/hostapd.eap_user ca_cert=/opt/eap/peap-alpha/CA.crt server_cert=/opt/eap/peap-alpha/CA.crt private_key=/opt/peap-alpha/CA.key ieee8021x=1 wpa=2 #changes for 802.11r: #only FT-clients: wpa_key_mgmt=FT-EAP #push R1 key to other APs: pmk_r1_push=1 #list of keyholders, AES-128 keys: openet1, openet2: r0kh=30:b5:c2:15:da:b2 ap2.example.com 1FC4BBA69DB8EB396A24249B406BA2A5 r0kh=30:b5:c2:15:73:1c ap1.example.com 1FC4BBA69DB8EB396A24249B406BA2A5 r1kh=30:b5:c2:15:73:1c 30:b5:c2:15:da:b2 1FC4BBA69DB8EB396A24249B406BA2A5 r1kh=30:b5:c2:15:da:b2 30:b5:c2:15:73:1c 1FC4BBA69DB8EB396A24249B406BA2A5 #NAS ID: nas_identifier=ap2.example.com #mobility domain: mobility_domain=a1b2 #interface to send/receive packets r0_key_lifetime=10000 ft_over_ds=0 r1_key_holder=30b5c215dab2 ft_psk_generate_local=1 #reassociation deadline in time units (TUs / 1.024 ms; range 1000..65535) reassociation_deadline=1000 wpa_pairwise=CCMP wpa_group_rekey=3600 rsn_pairwise=CCMP rsn_preauth=0 ctrl_interface_group=0 macaddr_acl=0 ssid=802.11R_AP country_code=IE ieee80211n=1 ieee80211d=1 hw_mode=g channel=7 Unfortunately when trying to execute fast transition, I have following issue (AP2 hostapd log): FT: STA R0KH-ID - hexdump(len=15): 61 70 31 2e 65 78 61 6d 70 6c 65 2e 63 6f 6d FT: Requested PMKR0Name - hexdump(len=16): 47 ad 87 45 3b ed d3 6d 36 0b 12 6c 40 78 10 e3 FT: Derived requested PMKR1Name - hexdump(len=16): 8f ee a9 44 89 6f ec 3e 8b 60 5f 9d fc 6e b7 8b FT: Send PMK-R1 pull request to remote R0KH address 30:b5:c2:15:73:1c FT: RRB send to 30:b5:c2:15:73:1c FT: Callback postponed until response is available res=-1 FT: Received authentication frame: STA=60:a3:7d:8c:6d:38 BSSID=30:b5:c2:18:a6:56 transaction=1 FT: Received authentication frame IEs - hexdump(len=167): 30 26 01 00 00 0f ac 04 01 00 00 0f ac 04 01 00 00 0f ac 03 0c 00 01 00 47 ad 87 45 3b ed d3 6d 36 0b 12 6c 40 78 10 e3 36 03 a1 b2 00 37 63 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 19 9b 8c db 66 d8 9b 63 24 e6 d8 cd 9c c9 e6 4b cd a5 36 95 4b 50 2d 43 6a 1d 50 e8 bc 5e e2 f4 03 0f 61 70 31 2e 65 78 61 6d 70 6c 65 2e 63 6f 6d 7f 08 04 00 00 00 00 00 00 40 dd 09 00 10 18 02 01 00 10 00 00 So I see there is a pull request send to AP-1. This request shall be made over air, as ft_over_ds=0. Unfortunately I cant even see such a request in wireshark... and there is no reply either... The phone connects to AP-2 with full authentication, so FT failed. Any advice? Does exchange of keys works over air or I need to setup it over DS? If setting it up over DS, do I need to have some special vlan configuration? Both APs are connected by Ethernet and a single switch.
