Not Logged In

django-axes 1.3.9

Keep track of failed login attempts in Django-powered sites.

Django Axes

django-axes is a very simple way for you to keep track of failed login attempts, both for the Django admin and for the rest of your site. The name is sort of a geeky pun, since axes can be read interpreted as:

  • “access”, as in monitoring access attempts
  • “axes”, as in tools you can use hack (generally on wood). In this case, however, the “hacking” part of it can be taken a bit further: django-axes is intended to help you stop people from hacking (popular media definition) your website. Hilarious, right? That’s what I thought too!

Requirements

django-axes requires Django 1.4 or later. The application is intended to work around the Django admin and the regular django.contrib.auth login-powered pages.

Installation

You can install the latest stable package running this command:

$ pip install django-axes

Also you can install the development version running this command:

$ pip install -e git+http://github.com/django-pci/django-axes.git#egg=django_axes-dev

Development

You can contribute to this project forking it from github and sending pull requests.

Running tests

Tests can be run, after you clone the repository and having django installed, like:

$ PYTHONPATH=$PYTHONPATH:$PWD django-admin.py test axes --settings=axes.test_settings

Configuration

First of all, you must add this project to your list of INSTALLED_APPS in settings.py:

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    ...
    'axes',
    ...
)

Next, install the FailedLoginMiddleware middleware:

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'axes.middleware.FailedLoginMiddleware'
)

Run python manage.py syncdb. This creates the appropriate tables in your database that are necessary for operation.

Customizing Axes

You have a couple options available to you to customize django-axes a bit. These should be defined in your settings.py file.

  • AXES_LOGIN_FAILURE_LIMIT: The number of login attempts allowed before a record is created for the failed logins. Default: 3
  • AXES_LOCK_OUT_AT_FAILURE: After the number of allowed login attempts are exceeded, should we lock out this IP (and optional user agent)? Default: True
  • AXES_USE_USER_AGENT: If True, lock out / log based on an IP address AND a user agent. This means requests from different user agents but from the same IP are treated differently. Default: False
  • AXES_COOLOFF_TIME: If set, defines a period of inactivity after which old failed login attempts will be forgotten. Can be set to a python timedelta object or an integer. If an integer, will be interpreted as a number of hours. Default: None
  • AXES_LOGGER: If set, specifies a logging mechanism for axes to use. Default: 'axes.watch_login'
  • AXES_LOCKOUT_TEMPLATE: If set, specifies a template to render when a user is locked out. Template receives cooloff_time and failure_limit as context variables. Default: None
  • AXES_LOCKOUT_URL: If set, specifies a URL to redirect to on lockout. If both AXES_LOCKOUT_TEMPLATE and AXES_LOCKOUT_URL are set, the template will be used. Default: None
  • AXES_VERBOSE: If True, you’ll see slightly more logging for Axes. Default: True
  • AXES_USERNAME_FORM_FIELD: the name of the form field that contains your users usernames. Default: username

Usage

Using django-axes is extremely simple. Once you install the application and the middleware, all you need to do is periodically check the Access Attempts section of the admin.

By default, django-axes will lock out repeated attempts from the same IP address. You can allow this IP to attempt again by deleting the relevant AccessAttempt records in the admin.

You can also use the axes_reset management command using Django’s manage.py.

  • manage.py axes_reset will reset all lockouts and access records.
  • manage.py axes_reset ip will clear lockout/records for ip

In your code, you can use from axes.utils import reset.

  • reset() will reset all lockouts and access records.
  • reset(ip=ip) will clear lockout/records for ip
  • reset(username=username) will clear lockout/records for username

Issues

Not being locked out after failed attempts

You may find that Axes is not capturing your failed login attempts. It may be that you need to manually add watch_login to your login url. For example, in your urls.py:

...
from django.contrib.auth.views import login, logout, password_change
from axes.decorators import watch_login
...
urlpatterns = patterns('',
    (r'^login/$', watch_login(login), {'template_name': 'auth/login.html'}),
...

Locked out without reason

It may happen that you have suddenly become locked out without a single failed attempt. One possible reason is that you are using some custom login form and the username field is named something different than “username”, e.g. “email”. This leads to all users attempts being lumped together. To fix this add the following to your settings:

AXES_USERNAME_FORM_FIELD = “email”

Changes

1.3.9 (2015-02-11)

  • Python 3 fix (#104)

1.3.8 (2014-10-07)

  • Rename GitHub organization from django-security to django-pci to emphasize focus on providing assistance with building PCI compliant websites with Django. [aclark4life]

1.3.7 (2014-10-05)

  • Explain common issues where Axes fails silently [cericoda]
  • Allow for user-defined username field for lookup in POST data [SteveByerly]
  • Log out only if user was logged in [zoten]
  • Support for floats in cooloff time (i.e: 0.1 == 6 minutes) [marianov]
  • Limit amount of POST data logged (#73). Limiting the length of value is not enough, as there could be arbitrary number of them, or very long key names. [peterkuma]
  • Improve get_ip to try for real ip address [7wonders]
  • Change IPAddressField to GenericIPAddressField. When using a PostgreSQL database and the client does not pass an IP address you get an inet error. This is a known problem with PostgreSQL and the IPAddressField. https://code.djangoproject.com/ticket/5622. It can be fixed by using a GenericIPAddressField instead. [polvoblanco]
  • Get first X-Forwarded-For IP [tutumcloud]
  • White listing IP addresses behind reverse proxy. Allowing some IP addresses to have direct access to the app even if they are behind a reverse proxy. Those IP addresses must still be on a white list. [ericbulloch]
  • Reduce logging of reverse proxy IP lookup and use configured logger. Fixes #76. Instead of logging the notice that django.axes looks for a HTTP header set by a reverse proxy on each attempt, just log it one-time on first module import. Also use the configured logger (by default axes.watch_login) for the message to be more consistent in logging. [eht16]
  • Limit the length of the values logged into the database. Refs #73 [camilonova]
  • Refactored tests to be more stable and faster [camilonova]

  • Replaced six imports with django.utils.six ones [amrhassan]
  • Replaced u string literal prefixes with six.u() calls to make it compatible with Python 3.2 [amrhassan]
  • Replaced assertIn`s and `assertNotIn`s with `assertContains and assertNotContains [fcurella]
  • Added py3k to travis [fcurella]
  • Update test cases to be python3 compatible [nicois]
