Thanks for the kill idea! It seems to be working nicely...
Just wanted to clarify though, if I kill wpa_supplicant, is there
something that is not cleaned gracefully? Would I have any problems if I
re-execute it after I kill it? It seems that functionally it reruns fine,
but I am thinking more of resources...
On a related note, why when I run hostapd, it creates a mon.wlan1
interface in addition to wlan1? I see something like the following when I
run hostapd :
root at td4:/home/td4/hostapd-0.7.2/hostapd# hostapd -dd
Configuration file: /etc/hostapd.conf
nl80211: Register Action command failed: ret=-114 (Operation already
nl80211: Register Action match - hexdump(len=1): 06
nl80211: Failed to register Action frame processing - ignore for now
nl80211: Add own interface ifindex 19
*nl80211: New interface mon.wlan1 created: ifindex=45*
nl80211: Add own interface ifindex 45 BSS count 1, BSSID mask
00:00:00:00:00:00 (0 bits)
nl80211: Added 802.11b mode based on 802.11g information
This again creates many problems in the debugging because each
handler interface sees a subset of the traffic that AP experiences and it is
very difficult to debug this.. (For more information on this please see my
previous message on the list :
Is there any way to solve this?
Many thanks in advance,
