[vox] Converting Ubuntu Box into an Access Point

[Benjamin Allistair]

I am trying to convert my Ubuntu box into an access point. I only have
my OS X laptop as a client to see if what I'm doing is working.

Basically what I have done is installed hostapd, bridge-utils, and
wireless-tools using apt-get.

I am loading the hostap_ drivers and have blacklists the orinoco_
drivers that come by default.

>From OS X I can see the SSID  but when I go to authenticate, I am only
given the option of using WEP and it won't authenticate anyways.

Below are snippets from what I thought to be relative config file
entries and system info.
-----------------------------------------------------------
Here is a snippet from my /etc/network/interfaces

auto eth0
iface eth0 inet dhcp

auto eth1
#iface eth1 inet manual
        #iwconfig wifi0 mode Master
        #iwconfig eth1 essid Oneil2

iface br0 inet dhcp
        bridge_ports eth0 eth1
        pre-up ifconfig eth0 0.0.0.0 up
        pre-up ifconfig eth1 0.0.0.0 up
        pre-up iwconfig wifi0 mode master
        pre-up brctl addbr br0
        pre-up brctl addbr eth0
        pre-up brctl addbr eth1
        post-down ifconfig eth0 0.0.0.0 down
        post-down ifconfig eth1 0.0.0.0 down
        post-down brctl delif br0 eth0
        post-down brctl delif br0 eth1
        post-down brctl delbr br0

------------------------------------------------------------
Here is my hostapd.conf
interface=eth1
bridge=br0
driver=hostap
logger_syslog=-1
logger_syslog_level=2
logger_stdout=-1
logger_stdout_level=2
debug=0
dump_file=/tmp/hostapd.dump
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
ssid=Oneil24
auth_algs=3
eapol_key_index_workaround=0
eap_server=0
wpa=3
wpa_psk_file=/etc/hostapd/wpa_psk
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP CCMP
stakey=0

------------------------------------
My /etc/hostapd/wpa_psk file looks like:
00:00:00:00:00:00 1234567890
