Problem with IAPP

[Khamidulla Inoyatov]

Dear all members,

I have following configuration for IAPP with EAP-TLS authentication:


MN(wpa_supplicant) <--wireless link-->AP_1(hostapd with eth0 interface for
IAPP)<--wired link-->AP_2(hostapd with eth0 interface for IAPP)<---wired
link->AAA Server(freeradius)


AP has two interface for wired and wireless link, eth0 and
ath0 respectively. However AP configured as bridge. Madwifi is used as
wireless network device's driver. Configuration file for hostapd as
following:

# Cleaned up example, see original hostapd.conf for comments.

interface=ath0
driver=madwifi

logger_syslog=-1
logger_syslog_level=0
logger_stdout=-1
logger_stdout_level=0

iapp_interface=eth0


dump_file=/tmp/hostapd.dump

ctrl_interface=/var/run/hostapd
ctrl_interface_group=wheel

##### IEEE 802.11 related configuration #######################################

ssid=IEEE80211r
macaddr_acl=0

##### IEEE 802.1X-REV related configuration ###################################

 However when i run i have following output:

What is problem? Why it shows that it cannot assign requested address?
Can any body share some knowledge on this?
