Re : [Résolu] Probleme de blocage avec fail2ban !
Donc merci pour ta réponse rapide je vais te poster mon fichier de config !!!
# Fail2Ban configuration file.
#
# This file was composed for Debian systems from the original one
# provided now under /usr/share/doc/fail2ban/examples/jail.conf
# for additional examples.
#
# To avoid merges during upgrades DO NOT MODIFY THIS FILE
# and rather provide your changes in /etc/fail2ban/jail.local

# The DEFAULT allows a global definition of the options. They can be override
# in each jail afterwards.

# "backend" specifies the backend used to get files modification. Available
# options are "gamin", "polling" and "auto".

# DNS Servers
# These jails block attacks against named (bind9). By default, logging is off
# with bind9 installation. You will need something like this:
#
# logging {
# channel security_file {
# file "/var/log/named/security.log" versions 3 size 30m;
# severity dynamic;
# print-time yes;
# };
# category security {
# security_file;
# };
# }
#
# in your named.conf to provide proper logging
# Word of Caution:
# Given filter can lead to DoS attack against your DNS server
# since there is no way to assure that UDP packets come from the
# real source IP
