Aardvark Proxy Middleman
This service acts as a middleman between frontend web servers and ticket submission services such as JIRA or BugZilla, and intercepts all data sent. POST Data is scanned for known offending words that are common in spam, and if found to be spam, the request is blocked. Aardvark keeps an internal list of offending IPs, and will block any subsequent POST requests from those IPs (until restarted).
port
: Which port to listen on for scans. For security purposes, Aardvark will only bind to localhost. Default is 1729proxy_url
: The backend service to proxy to if request is saneipheader
: The header to look for the client's IP in. Typically X-Forwarded-For.spamurls
: Specific honey-pot URLs that trigger a block regardless of the actionignoreurls
: Specific URLs that are exempt from spam detectionpostmatches
: A list of keywords and/or regexes that, if matched, will block the requestmultimatch
: A combination blocker. If a required
keyword or regex is matched, the request will be blocked only if one or more auxiliary
keywords/regexes are also matchedTo enable as a pipservice, add the following minimal hiera yaml to your node config:
pipservice: aardvark-proxy: tag: main
Follow these steps to run manually (assuming you have pipenv installed):
git clone https://github.com/apache/infrastructure-aardvark-proxy.git aardvark-proxy
cd aardvark-proxy
pipenv install -r requirements.txt
pipenv run python3 aardvark.py
As Aardvark is a proxy middleman for specific purposes, you will preferably need a web server in front. The example below relays all POST requests for /foo/bar through Aardvark, while letting all GETs etc go directly to the backend service.
Assuming Aardvark is listening on port 4321
and the real backend service is on port 8080
:
# Send all POST requests through Aardvark RewriteEngine On RewriteCond %{REQUEST_METHOD} POST RewriteRule ^/(.*)$ http://localhost:4321/$1 [P] # Rest goes to backend directly ProxyPass / http://localhost:8080/foo/bar/
