hostap issues on etch box...

Tue Mar 6 06:38:14 PST 2007

Hi all,

I'm trying to set up my debian box (etch, kernel 2.6.18, hostapd 0.5.5)
as a wifi ap using a DWL-520 wifi PCI card with the madwifi driver.
Note: this works fine if I use my wifi card as managed.

Bridging is enabled in my kernel.

Here is my configuration files:

1) /etc/network/interfaces:
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.1.60 <http://192.168.1.60>
gateway 192.168.1.10 <http://192.168.1.10>
netmask 255.255.255.0 <http://255.255.255.0>
  up /etc/init.d/snort start eth0

iface ath0 inet static
wireless-mode master
wireless-channel 11

auto br0
iface br0 inet static
address 10.0.0.1 <http://10.0.0.1>
netmask 255.255.255.0 <http://255.255.255.0>
bridge_ports eth1 ath0

2) /etc/hostapd/hostapd.conf

Fisrt, when I start hostapd, it complains:

{pts/1}:~/[6]/> /etc/init.d/hostapd start
Starting advanced IEEE 802.11 management:
hostapdioctl[IEEE80211_IOCTL_SETMLME]: Invalid argument

Second, it complains that it is associated/disassociated, etc.
Here is the log file (-dd option):

And so on...

Third, my kernel is very unstable when hostapd is running :-(

What's wrong ?

Any suggestion are welcome.

Thanks in advance.
