[Voyage-linux] hostapd & ath9k

[Frank Parker]

Fresh install of voyage-0.6.5 on a "Generic PC".  Trying to understand
how to turn this ATOM-based PC device into an access point.  It has an
Atheros wireless card using athk9 kernel module.

I see that hostapd is included with voyage, and I have read a lot of
documentation but it's not clear to me how to configure it.

The module is loaded:

voyage:/# lsmod | grep ath
ath9k                 281864  0
mac80211              142608  1 ath9k
rfkill                  8320  2 ath9k
cfg80211               51732  2 ath9k,mac80211
led_class               3428  1 ath9k


For some reason, there is a wlan0 interface instead of ath0 like most
of the examples I've read.

voyage:/# ifconfig ath0
ath0: error fetching interface information: Device not found

voyage:/# ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr 0c:ee:e6:cb:f4:54
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)


The iwconfig command gives this:

voyage:/# iwconfig wlan0
wlan0     IEEE 802.11bgn  ESSID:""
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0



Do I need to edit these?
/etc/default/hostapd
/etc/hostapd/hostapd.conf
/etc/network/interfaces?
others?
