Sticky Elephant

Sticky Elephant is a medium-interaction PostgreSQL honeypot.

sticky_elephant [options]
    -c, --config CONFIG              Configuration file to read
    -h, --help                       Display this screen

Usage

Either install the gem and

% sticky_elephant

or clone the repo and

% ./bin/sticky_elephant

Configuration

sticky_elephant.conf is a YAML file that defines Sticky Elephant's behavior. You can tell Sticky Elephant what configuration file to use with -c. The configuration file looks like this:

:log_path: "./sticky_elephant.log"
:port: 5432
:host: 0.0.0.0
:debug: true
:abort_on_exception: false
:use_hpf: true
:hpf_host: 127.0.0.1
:hpf_port: 10000
:hpf_ident: 24b6875e-03f1-4c2a-b5b0-11af1f49e2bb
:hpf_secret: woofwoofcharlesisagooddog

host and port define the host address and port to which Sticky Elephant should bind. log_path is the log to which Sticky Elephant will write. Do note that HPFeeds logs go to stdout and are separate from Sticky Elephant application logs. debug turns on debug-level logging; abort_on_exception kills threads when they encounter an exception. The hpf-prefixed options are for configuring the HPFeeds server to which Sticky Elephant should report queries and connections.

Installation

You can just run sticky_elephant in a tmux session, that certainly works. If you prefer to set things up a bit nicer, make a sticky_elephant user and give them a home directory. Put your config file in /etc/sticky_elephant/sticky_elephant.conf and ensure that the sticky_elephant user can read it. Then you can use this systemd service definition to run sticky_elephant at boot:

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
