Django middleware for blocking IPs listed in stopforumspam.com
Tired of comment spam, form spam and dumb crawlers? A django application that provides middleware for blocking IPs listed in stopforumspam.com’s database. It only reacts on POST requests, so don’t worry about a huge table of rules having to be passed at every request. It’s quite painless.
A simple management command is provided for updating the database from stopforumspam.com:
manage.py sfsupdate [--force]
Using this command, all IPs are stored in Django models, and using django-admin, it’s possible to add your own extra IP addresses on a permanent database.
- Django 1.7+
- Python 2.7 and 3+
Install the latest release from pypi:
sudo pip install stopforumspam
Add this to settings.MIDDLEWARE_CLASSES:
Then add this to INSTALLED_APPS:
python manage.py syncdb
To insert all the IPs run this command, which you should make a cronjob (run it every 24h):
python manage.py sfsupdate
The following options exist for your project’s settings.py file:
To check ALL POST requests:
SFS_ALL_POST_REQUESTS = True
To ignore some URLS:
SFS_URLS_IGNORE = ["url_name", "/url/path"]
To only include some URLS (only works if SFS_ALL_POST_REQUEST=False):
SFS_URLS_INCLUDE = ["url_name", "/url/path"]
If your application is behind a set of proxy, you can use a specific HTTP Header as a source of the client IP:
SFS_HTTP_HEADER = "X-Forwarded-For"
Synching with stopforumspam.com
Be nice to their servers and remember that they have strict enforcements on the files that they offer. So before you start testing, you could consider using a local file as a test.
To configure where to download the file from (you can MAX download 2 times a day) - see http://www.stopforumspam.com for more resources:
SFS_SOURCE_ZIP = "http://www.stopforumspam.com/downloads/listed_ip_7.zip"
But you should really use a local file if you have more than 1 Django project with stopforumspam running from the same IP address. To do this, use a local protocol:
SFS_SOURCE_ZIP = "file:///path/to/listed_ip_7.zip"
You can control how often at most the update should be performed:
SFS_CACHE_EXPIRE = 1 #day
…and how long back the log should remember the rejection of POSTS and IPs:
SFS_LOG_EXPIRE = 1 #days
Remember to configure this as well – it’s the name of the file inside the .zip file:
SFS_ZIP_FILENAME = "listed_ip_7.txt"
For testing you can force all requests to be checked:
SFS_FORCE_ALL_REQUESTS = True
You probably want to automatically update the list of blocked IP addresses every 24 hours or 48 hours. To do that, you can insert a line in crontab:
0 2 * * * python /your/project/path/manage.py sfsupdate -q
The above would update at 2 AM every night. If you have several projects and sync them with a local file, you can add:
0 2 * * * wget -O /tmp/listed_ip_7.zip http://www.stopforumspam.com/downloads/listed_ip_7.zip ; python /your/project/path/manage.py sfsupdate -q
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
