Salut,
Je me suis inspiré du script de ricardo mais quand je scan ma machine, il y a 4 ports, le 22,80,53 et 111 alors que je n’ai pas encore ajout" de règles, est-ce fail2ban? Dois-je quand-même ouvrir les ports 22,80 et 443?
Que me conseillez-vous comme règle pour lire les logs.
Je suis un peu perdu.
