Estou tentando deixar meu Raspberry Pi funcionar como um ponto de acesso, mas continuo tendo alguns problemas. Especificamente quando se trata de falsificar o endereço MAC. O objetivo é criar um hotspot streetpass do Nintendo 3DS em casa. Estou seguindo este guia principalmente.
Primeiro, as coisas que estou usando: Raspberry Pi Modelo B com um adaptador USB sem fio TP-Link TL-WN725N v2 com chipset Realtek RTL8188EUS. Este é recomendado para fins de AR.
Kernel em execução no Raspbian GNU / Linux 7 instalado através do NOOBS v1.3.9 (2014-07-08):
Linux raspberrypi 3.12.22+ #691 PREEMPT Wed Jun 18 18:29:58 BST 2014 armv6l GNU/Linux
lsusb no adaptador wlan:
Bus 001 Device 004: ID 0bda:8179 Realtek Semiconductor Corp.
Eu instalei o driver por meio de este guia . A execução de iwlist wlan0 scan retorna com êxito uma lista de redes sem fio.
Então eu mudei para instalar os pacotes necessários. Primeiro eu instalei o HostAPD através do este guia , mas encontrei alguns problemas (tenho um erro ioctl[RTL_IOCTL_HOSTAPD]: Invalid argument ) Eu tentei o que foi sugerido aqui . Com sucesso.
Depois disso, instalei os pacotes isc-dhcp-server e bridge-utils.
Eu fiz um arquivo de configuração de teste para o hostapd (/tmp/test.conf):
# Basic configuration
interface=wlan0
ssid=wifi
bssid=4E:53:50:4F:4F:46
channel=5
bridge=br0
# WPA and WPA2 configuration
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
# Hardware configuration
driver=rtl871xdrv
ieee80211n=1
hw_mode=g
device_name=RTL8192CU
manufacturer=Realtek
Depois de executar o hostapd /tmp/test.conf, estou recebendo o seguinte erro (parte do retorno):
+rtl871x_sta_deauth_ops, ff:ff:ff:ff:ff:ff is deauth, reason=2
Using interface wlan0 with hwaddr e8:94:f6:1c:4a:dd and ssid 'wifi'
Ele retorna ao endereço MAC real. A execução de uma depuração retorna o seguinte:
root@raspberrypi:~# hostapd -dd /tmp/test.conf

Eu pesquisei e procurei, mas o que quer que eu tente, ele continua voltando para o bssid original. O que posso fazer para que isso funcione do jeito que eu quero?
Apenas no heads-up: sou novo no linux.

iw list retorna command not found , mas o comando iwlist está disponível se eles compartilham um propósito semelhante.
edit2: eu instalei iw . A execução de iw list retorna isso:
root@raspberrypi:~# iw list
