bonjour a tous
a la base j’utilise guarddog mais j’aimerais m’en passer donc,
je suis en train d’apprendre IPTABLES et j’ai regarder le beau tuto de ricardo dans T&A
j’ai quelques questions (evidement !!
) en premier :
j’aimerais savoir ce que vous penser de mon IPTABLE -L
car au demarrage j’ai une ligne du style iptable : bad rules
y voyer-vous des erreurs ou autres ou il n’y a rien a dire … merci :
IPTABLES -L
