así que cambio mi dirección MAC macchanger -A wlp68s0b1
en el arranque con crontab, esto es lo que sucede cuando me desconecto y vuelvo a conectar:
mientras se conecta después del arranque:
rahman@debian:~$ macchanger -s wlp68s0b1
Current MAC: 00:22:31:c6:38:45 (SMT&C Co., Ltd.)
Permanent MAC: 00:00:00:00:00:00 (FAKE CORPORATION)
después de desconectar:
rahman@debian:~$ macchanger -s wlp68s0b1
Current MAC: 16:7b:e7:3c:d3:cd (unknown)
Permanent MAC: 00:00:00:00:00:00 (FAKE CORPORATION)
después de volver a conectar:
rahman@debian:~$ macchanger -s wlp68s0b1
Current MAC: 00:00:00:00:00:00 (FAKE CORPORATION)
Permanent MAC: 00:00:00:00:00:00 (FAKE CORPORATION)
y así sucesivamente, y con cada desconexión obtengo una dirección MAC aleatoria diferente que se desvanece al volver a conectarme, dándome mi dirección MAC real, ¿qué causa eso y cómo detenerlo?
algunas salidas:
