Meine Firewall ist derzeit inaktiv.
systemctl status firewalld firewalld.service Loaded: masked (/dev/null) Active: inactive (dead)
Ich habe den folgenden Befehl verwendet, um die Firewall zu aktivieren
# systemctl unmask firewalld
aber ich habe diesen Fehler bekommen:
# 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
