Well, the following in rc.conf

wlans_ath0="wlan0 wlan2"
create_args_wlan0="bssid wlanmode hostap country DE authmode wpa ssid COYOTE"
ifconfig_wlan0="ssid COYOTE mode 11g pureg up"
create_args_wlan2="bssid wlanmode hostap country DE authmode wpa ssid
COYOTE_GUEST"
ifconfig_wlan2="ssid COYOTE_GUEST mode 11g pureg up"

Does not quite work, I'm left with:

(from dmesg)
Setting hostname: coyote.spoerlein.net.
bridge0: Ethernet address: 02:ac:6e:56:db:00
Created clone interfaces: bridge0.
wlan0: Ethernet address: 68:a3:c4:51:44:99
wlan2: Ethernet address: 6e:a3:c4:51:44:99
ifconfig: SIOCS80211: Device busy
ath0: stuck beacon; resetting (bmiss count 4)

(not that there's no echo for creating wlan devices, that should maybe
be added?)

Anyway, I thus get this:

Then I also had to bounce the hostapd on wlan0 and start the one on
wlan2 and it looks very promising currently. Is it possible that there
is a timing issue involved and doing it manually works better than
when the startup scripts run through this?


I've now got this working version that seems to be solid and comes up
during boot w/o manual intervention.

/etc/rc.conf:
wlans_ath0="wlan0 wlan2"
create_args_wlan0="bssid wlanmode hostap country DE authmode wpa ssid COYOTE"
create_args_wlan2="bssid wlanmode hostap country DE authmode wpa ssid
COYOTE_GUEST"
(no ifconfig_wlanX settings, I'm using a bridge for these, no hostapd!)

/etc/rc.local:
#!/bin/sh
/etc/rc.d/hostapd start wlan0
sleep 2
/etc/rc.d/hostapd start wlan2

and I get:

root@coyote:~# ifconfig wlan0; ifconfig wlan2
wlan0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST>
metric 0 mtu 1500
        ether 68:a3:c4:51:44:99

root@coyote:~# pgrep -fl hostapd
3071 /usr/sbin/hostapd -P /var/run/hostapd-wlan2.pid -B /etc/hostapd-wlan2.conf
3061 /usr/sbin/hostapd -P /var/run/hostapd-wlan0.pid -B /etc/hostapd-wlan0.conf

Now I need to un-bridge the wlan2, put in a firewalled guest network
and tweak pf accordingly. Or maybe I'll use a pf-based filtering
bridge. And I still need an USB fob for that 5GHz AP.

Thanks!
Uli
