Re: [Wifiadmin-users] No wireless Interfaces found

###Hello Vasos,
###I have doublechecked that /proc/net/wireless file on my hostapd server 
and hostapd client
###On hostapd client (laptop) that file is very as expected. But that is not
case at all on hostapd server.
###On hostapd server /proc/net/wireles file is emtpy.

###/proc/net/wireless file on my hostapd server

###ifconfig command will show wlan device on my server - that is not any 
problem. 
###There is also another device called mon.wlan0 - I dont know what is it.

contain

###As /proc/net/wirelles is very fine on laptop - client. I would say that 
missing of 
###/proc/net/wireless file is caused by hostapd daemon.
###I need to figure out if /proc/net/wireless can be corrected by some 
config change
###in hostapd config file. Or maybe hostapd rpm package is not compiled with
some option
###which deals with /proc/net/wireless file.
###Also absence of /proc/net/wireless file might be caused by existence of 
bridge device.
###I have configured bridge in /etc/sysconfig/network-scripts but device 
wlan0 is added to bridge
###by hostapd daemon with option br=wlan0

/etc/hostapd/hostapd.conf :
...
interface=wlan0
bridge=br0
...

[root@manitou network-scripts]# cat ifcfg-br0
DEVICE=br0
BOOTPROTO=static
BROADCAST=192.168.199.255
IPADDR=192.168.199.1
NETMASK=255.255.255.0
NETWORK=192.168.199.0
ONBOOT=yes
TYPE=Bridge
NM_CONTROLLED="no"

###All right - now we have root cause - why I do not have no wireless 
interface in 
###the wifiadmin detected.
###I will try to find out if I can push my server somehow to
###start to output to /proc/net/wireless file ...

###Thanks.
###Regards.
###Rad.

That's why then you are not seeing wireless interfaces.

Can you see them with iwconfig ?
 
 As far as i know wifiadmin has not been tested with FC (until now :)
Maybe, also, any software or kernel updates ?

If you find anything about that please report.

Thank for your prompt reply.

I can not access my server now. I will send you output evening.
But I have already been looking to that file /proc/net/wireless and there 
was pretty much nothing.

There was only header row but not any entry.

Did not have a time to google if it is bug or fedora 17 feature.

Thanks.
Rad.

Hello Vasos,

Thank you very much for your reply and your support.

I have deployed wifiadmin version 0.2.5 but unfortunately that issue "No 
wireless Interfaces found" has not been solved.

here are commands which I can see on the webbrowser screen:

[11:40][V] cat /proc/net/wireless
[11:40][V] uname -srmo
[11:40][V] cat /proc/sys/kernel/hostname
[11:40][V] cat /proc/uptime

[11:43][V] /sbin/ifconfig -s
[11:44][V] /sbin/ifconfig 'br0'
[11:44][V] /sbin/ifconfig -s


Please suggest, please?
Thank you very much.
