I am using hostapd, wireless tools with madwifi for my wireless ap in my board. The WEP, WPA-PSK connections and communications between my board with linux and my desktop PC, Windows XP SP2 (with Olitec USB wireless) are fine.

But when I configured the WPA type, the connection seems established but shows the status "TKIP - Key Absent" in the security dialog box.

Anyone faced this problem?

Am attaching the conf files and the connection status.

In the AP side am complaining .

I am using the in built radius server conf with the hostapd 0.4.7

hostapd.conf

interface=ath0

driver=madwifi

logger_syslog=0

logger_syslog_level=0

logger_stdout=0

logger_stdout_level=0

debug=0

eapol_key_index_workaround=1

dump_file=/tmp/hostapd.dump.0.0

ssid=Renjith G wpa

wpa=1

wpa_passphrase=mypassphrase

wpa_key_mgmt=WPA-EAP

wpa_pairwise=TKIP CCMP

wpa_group_rekey=600

macaddr_acl=2 /* commented */

ieee8021x=1 /* commented */

eap_authenticator=1

own_ip_addr=172.16.25.1

nas_identifier=renjithg.com

auth_server_addr=172.16.25.1

auth_server_port=1812

auth_server_shared_secret=key1

ca_cert=/flash1/ca.crt

server_cert=/flash1/server.crt

eap_user_file=/etc/hostapd.eap_user

hostapd.eap_user

"*@renjithg.com" TLS

And the commands am using are

wlanconfig ath0 create wlandev wifi0 wlanmode ap

iwconfig ath0 essid Renjith channel 6

ifconfig ath0 192.168.25.1 netmask 255.255.255.0 up

hostapd -ddd /etc/hostapd.conf

Please correct if am wrong ..

Also am getting the debug messages on my AP when am connecting in my windows machine through WPA

~/wlanexe # ./hostapd -ddd /etc/hostapd.conf

Configuration file: /etc/hostapd.conf Line 18: obsolete eap_authenticator used; this has been renamed to eap_server
