Let’s start with creating a new filter:

vi /etc/fail2ban/filter.d/odoo.conf

Paste the content from bellow code:


# Read common prefixes. If any customizations available -- read them from
# common.local
before = common.conf


failregex = INFO:openerp.addons.base.res.res_users:Login failed for db:.* login:.*\n.*INFO:werkzeug: - - \[.*\] \"POST /web/login .*\" 200 -
         - \[.*\] \"POST /web/database/(drop|duplicate|create) HTTP/2.0\"

ignoreregex =
journalmatch = _SYSTEMD_UNIT=odoo.service + _COMM=odoo


maxlines = 2

Add those line in jail.local

enabled = true
port    = 443,80,8069
filter  = odoo
logpath = /var/log/syslog
maxretry = 5
bantime  = -1
findtime = 1h

Change the value of syslog in the /etc/odoo/openerp-server.conf

syslog = True

Restart Odoo then fail2ban to apply modification.
