Mon pare-feu est actuellement inactif.
systemctl status firewalld firewalld.service Loaded: masked (/dev/null) Active: inactive (dead)
J'ai utilisé la commande suivante pour activer le pare-feu
# systemctl unmask firewalld
mais j'ai eu cette erreur:
# systemctl unmask firewalld
Failed to issue method call: Access denied
# sudo systemctl restart firewalld
Failed to issue method call: Unit firewalld.service failed to load: No such file or directory.
# sudo systemctl enable firewalld
Failed to issue method call: Access denied
lsmod | grep iptab
les modules chargés?
