Interface 'ap0' does not exists error #105

Open tamlok opened 9 years ago

tamlok commented 9 years ago

My system is Opensuse 13.2 + xfce4. When I tried to sudo create_ap wlp9s0 enp4s0f2 <name> <pass>, it said that:

Config dir: /tmp/create_ap.wlp9s0.conf.KbwbNbaa
PID: 3068
Network Manager found, set ap0 as unmanaged device... DONE
Creating a virtual WiFi interface... 
ERROR: Interface 'ap0' does not exists.
       It's probably renamed by a udev rule.

So what should I do? Thanks very much!

In your case you can use --no-virt. But paste me the output of:

iw list
iw dev

@oblique Hi, when I use --no-virt, it said that:

Is your OpenSuse a clean installation or an upgrade from previous version?

tamlok commented 9 years ago

@oblique It is a clean installation. :)

tamlok commented 9 years ago

@oblique Do I have to install the dependencies manually?

oblique commented 9 years ago

Yes. I will try to reproduce the problem on my free time.

tamlok commented 9 years ago

@oblique I skipped installing the dependencies before. I am trying to install them and try again. Thanks very much!

oblique commented 9 years ago

Ok, let me know if the dependencies was the problem.

tamlok commented 9 years ago

@oblique It remains the same. Then I tried use -m bridge, it worked and my Android phone could find the SSID. However, my phone just keep connecting to the AP again and again, saying something like "authenticating".

oblique commented 9 years ago

The "authenticating" can be anything. Maybe someone is doing deauthentication attack in that channel, or you wrote wrong passphrase, or your adapter doesn't support WPA1 + WPA2 at the same time (you can use -w 2 to enable only WPA2), or you need to install haveged because your entropy is low.

I just fixed the permission denied problem you mention above. You can now use the --no-virt option until I fix the udev problem. However I don't know if the udev problem is fixable without editing manually some udev configuration files.

tamlok commented 9 years ago

After update, using --no-virt in default mode works well! Thanks very much! This app facilitates sharing WiFi in Linux.
