Either AP or IBSS, but not both

[Tuc at Beach House]

Sorry... Got away from me

Hi,

Raspberry Pi Model B+, Linux blue 3.12.28+ #709 PREEMPT Mon Sep 8 15:28:00
BST 2014 armv6l GNU/Linux, hostapd v2.3 (defconfig), Ralink using rt2800usb
driver.

What I'm trying to accomplish is using a single interface to be an AP on
one SSID, and ad-hoc on another SSID. The problem is that I can either do
one, or the other, but not both...

root at blue:~# iwconfig wlan1
wlan1     IEEE 802.11bgn  ESSID:off/any
          Mode:Managed  Access Point: Not-Associated   Tx-Power=0 dBm
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:on

So if I set up ad-hoc, works fine :

root at blue:~# iw dev wlan1 interface add wlan10 type ibss
root at blue:~# iwconfig wlan10
wlan10    IEEE 802.11bgn  ESSID:off/any
          Mode:Ad-Hoc  Cell: Not-Associated   Tx-Power=0 dBm
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:on

root at blue:~# iwconfig wlan10 essid WEDDING
root at blue:~# ifconfig wlan10 10.4.4.8 netmask 255.255.255.0
root at blue:~# ping -c2 new
PING new.wedding.ramolaandscott,com (10.4.4.6) 56(84) bytes of data.
64 bytes from new.wedding.ramolaandscott,com (10.4.4.6): icmp_req=1 ttl=64

64 bytes from new.wedding.ramolaandscott,com (10.4.4.6): icmp_req=2 ttl=64
time=1.02 ms

2 packets transmitted, 2 received, 0% packet loss, time 1001ms
rtt min/avg/max/mdev = 1.024/2.268/3.512/1.244 ms


Now invoke hostapd with the following /etc/hostapd/hostapd.conf :

root at blue:~# cat /etc/hostapd/hostapd.conf
interface=wlan1
ssid=FREE
hw_mode=g
channel=1
root at blue:~# /usr/local/bin/hostapd -dd /etc/hostapd/hostapd.conf
(Please see http://pastebin.com/cjqukwyH)


But if I reboot and try backwards :

root at blue:~# hostapd -dd /etc/hostapd/hostapd.conf
(Please see http://pastebin.com/Tdc5dz81)


And its fine, but then :

root at blue:~# iw dev wlan1 interface add wlan10 type ibss
root at blue:~# iwconfig wlan10
wlan10    IEEE 802.11bgn  ESSID:off/any
          Mode:Ad-Hoc  Cell: Not-Associated   Tx-Power=20 dBm
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:on

root at blue:~# iwconfig wlan10 essid WEDDING
root at blue:~# ifconfig wlan10

root at blue:~# ping -c2 new
PING new.wedding.ramolaandscott,com (10.4.4.6) 56(84) bytes of data.

--- new.wedding.ramolaandscott,com ping statistics ---

Any idea where to look or what to do to get them to work and play together?

Thanks, Tuc
