wpa_suppliccant complains about " Name not unique on network"

[Sergio Belkin]

Hi,

I've trying to simulate a few of stations associating to an AP, so
added a virtual interface with:

sudo iw dev wlan0 interface add sta0 type managed

And then I run:

sudo ./wpa_supplicant -dd  -c /tmp/wpa-psk-tkip.conf -iwlan0 -N -c
/tmp/wpa-psk-tkip-2.conf -ista0

But it fails, the output is as follows
