CiviCRM is a free, libre and open source software constituent relationship management solution. CiviCRM is web-based, internationalized, and designed specifically to meet the needs of advocacy, non-profit and non-governmental groups. Integration with both Drupal and Joomla! content management systems gives you the tools to connect, communicate and activate your supporters and constituents.

matahari is a python script designed to provide a basic non-interactive shell on remote systems behind firewalls. It is intended for use by system administrators who may need some emergency backdoor to access a firewalled machine.

Once you set up the script on the target machine (namely, the client) it begins trying to retrieve commands from the master machine (the server). The time between periodic requests (polls) can be configured to suit different needs ranging from low latency (frequent polls) to stealthier behaviours.
