Build status Test coverage Code Health

strongTNC is a Trusted Network Connect (TNC) extension for the strongSwan VPN solution. It allows the definition and enforcement of TNC policies that apply to all VPN clients and must be fulfilled with each connection attempt.

Development Setup

strongTNC uses Django (currently version 1.11.22). It is recommended to use the pip and virtualenv tools to ease the dependency management. They can be installed via your package manager on most Linux distributions.

If you're new to these tools: Pip is the de-facto Python package manager (similar to apt-get or yum). And virtualenv is a tool that allows you to have multiple Python installations side-by-side, inside a directory. A quickstart guide can be found here.

Non-Python Dependencies

You need to install the following packages in order to be able to build all the needed Python dependencies:

  • python headers (Debian: python-dev)
  • libxml (Debian: libxml2-dev)
  • libxslt (Debian: libxslt-dev)

Environment, Dependencies

First, create a virtualenv:

cd /path/to/strongTNC/
virtualenv --no-site-packages VIRTUAL
source VIRTUAL/bin/activate

Then install the dependencies:

pip install -r requirements.txt


Create a local settings.ini file:

cp config/settings.sample.ini config/settings.ini
$EDITOR config/settings.ini

If this is not a production setup, change the DEBUG setting in settings.ini from 0 to 1.

Create the databases:

./ migrate --database meta
./ migrate

Set the default passwords:

./ setpassword

If you want to use the Django-Admin view (/admin), create a superuser account:

./ createsuperuser --database meta

In case you want to change the password of a user:

./ changepassword admin-user --database meta


Now you can start the development server.

./ runserver

The web interface should be available on http://localhost:8000/.


If you want to use the django debug toolbar, install it via pip:

pip install django-debug-toolbar

Then start the server with the setting [debug] DEBUG_TOOLBAR = 1 (in settings.ini).

To print all executed SQL queries to stdout, start the server with the setting [debug] SQL_DEBUG = 1 (in settings.ini).


Install pytest & dependencies:

pip install -r requirements-tests.txt

Run the tests:


Run a specific test file:

./ tests/<filename>

Run only tests matching a specific pattern:

./ -k <pattern>

Run only tests that failed the last time:

./ --lf

Run tests without coverage:

./ --no-cov

XMPP-Grid Publishing Interface

strongTNC can publish real-time information on new SWID tags:

Published item strongswan.org__Debian_7.11-armv7l-smbclient-2~3.6.6-6~deb7u15 to sacm/swidtags:
  "tagId": "Debian_7.11-armv7l-smbclient-2~3.6.6-6~deb7u15",
  "versionStr": "2:3.6.6-6+deb7u15",
  "packageName": "smbclient",
  "uri": ""

and push create (action: 1) or remove (action: 2) SWIMA events received from endpoints:

Published item 270aea08-d972-478c-b414-23abb0e82f1d332 to sacm/events:
  "device": {
    "description": "Raspi 3",
    "value": "565feb9e8462870dba884ce540a0768d68829873"
  "action": 1,
  "tag": {
    "recordId": 1413,
    "sourceId": 1,
    "softwareId": "strongswan.org__Debian_7.11-armv7l-smbclient-2~3.6.6-6~deb7u15"
  "event": {
    "timestamp": "2017-11-22T15:04:35Z",
    "epoch": "1594045818",
    "eid": "82"

in JSON format to an XMPP-Grid by setting [xmpp] USE_XMPP = 1 and configuring various parameters (in settings.ini). Here is an example configuration:

password: <password>
cacert: /etc/swanctl/x509ca/strongswanCaCert.pem
use_ipv6: 0
node_events: sacm/events
node_swidtags: sacm/swidtags
