Hello, I have a problem with my hostap.
The configuration file is the following:

file "madwifi.conf"

interface=ath0
bridge=wifi0
driver=madwifi
logger_syslog=-1
logger_syslog_level=4
logger_stdout=-1
logger_stdout_level=4
debug=4
dump_file=/tmp/hostapd.dump
ssid=pfc

own_ip_addr=127.0.0.1

auth_server_shared_secret=carpeher
acct_server_addr=127.0.0.1
acct_server_port=1813
acct_server_shared_secret=carpeher

I have this log when I do the following:

[root at inf-205-91 hostapd-0.4.8]# hostapd -dd -K -t madwifi.conf
Configuration file: madwifi.conf
Configure bridge wifi0 for EAPOL traffic.

You can realize that I have the message "Network is down". I dont know why 
that happends, because the interface is up (I have the same message wheather 
the interface is up either is down). The last line "Wireless event: 
cmd=0x8b19 len=12" happens when I do "ifconfig ath0 up"
Now, I do:

[root at inf-205-91 hostapd-0.4.8]# iwconfig ath0
ath0      IEEE 802.11g  ESSID:"pfc"

Notice that "Encryption key:off"


No, I try to connect my client. (Wireless pcmcia card, Orinoco, firmware 
Lucent/Agare 7.28, but I have tried also with my ipw2200bg, and I have the 
same problem).

I do on my client:

[root at inf-205-245 ~]# iwlist eth2 scanning
eth2      Scan completed :
          Cell 01 - Address: 00:13:46:E3:1E:81
                    ESSID:"pfc"
                    Mode:Master
                    Frequency:2.412 GHz (Channel 1)
                    Signal level:-73 dBm  Noise level:-66 dBm
                    Encryption key:on


Notice that here happears "Encryption key:on".

So, that is my first question, why?

Good, I thought I am going to do the following on the hostap:

[root at inf-205-91 hostapd-0.4.8]# iwconfig ath0 key off

and I had the following:

Wireless event: cmd=0x8b2a len=12
Wireless event: cmd=0x8b19 len=12

good, maybe it was a good idea xD, because on the client i have:

[root at inf-205-245 ~]# iwlist eth2 scanning
eth2      Scan completed :
          Cell 02 - Address: 00:13:46:E3:1E:81
                    ESSID:"pfc"
                    Mode:Master
                    Frequency:2.412 GHz (Channel 1)
                    Signal level:-75 dBm  Noise level:-97 dBm
                    Encryption key:off


hehe, awesome!, but when I do on the client:

[root at inf-205-245 etc]# iwconfig eth2 essid pfc

and the hostap gets crazy like:

Also, I have tries to do something with the xsupplicant, with the following 
configuration file:

(my xsupplicant configuration)

network_list = all
default_netname = default
logfile = /var/log/xsupplicant.log
default
{
  type = wireless
  allow_types = all
  identity = root
  eap-md5 {
      username = root
      password = carpeher
  }
}

but it doesnt work either.

so, could anyone please help me? I am stopped here and I dont know how to 
follow.

Thank you in advance.
