Bonsoir
Mon problème est simple, je veux seulement permettre à mon utilisateur l’utilisation de les interfaces réseaux
que dois-je faire ?
user@pc:~$ tshark -i wlan0
Capturing on wlan0
tshark: The capture session could not be initiated (You don't have permission to capture on that device).
Please check to make sure you have sufficient permissions, and that you have the proper interface or pipe specified.
0 packets captured
Sous linux, tout est fichier, y compris les interfaces.
Donc un chmod sur /dev/wlan0 devrait faire l’affaire.
ou pourquoi pas une ligne de config dans sudo en fonction de ce que tu veux lui permettre de faire…
/dev/wlan0 n’existe pas
root@pc:/# ls -l /dev
