donc je change mon adresse MAC avec macchanger -A wlp68s0b1
au démarrage avec crontab, voici ce qui se passe lorsque je me déconnecte et me reconnecte:
lors de la connexion après le démarrage:
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)
après déconnexion:
rahman@debian:~$ macchanger -s wlp68s0b1
Current MAC: 16:7b:e7:3c:d3:cd (unknown)
Permanent MAC: 00:00:00:00:00:00 (FAKE CORPORATION)
après reconnexion:
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)
et ainsi de suite, et à chaque déconnexion, j'obtiens une adresse MAC aléatoire différente qui s'estompe à la reconnexion en me donnant ma véritable adresse MAC, qu'est-ce qui cause cela et comment l'arrêter?
quelques sorties:
