Project:Tool Access Control/ACNet

Summary

This page aims to scope out the different projects that work together as part of the Access Control Network. The main components are:

• ACNode - The clients that sit on the tool that is being controlled and manage physical access by reading the rfid card.
• ACServer - The server stores the authentication information and pulls membership information from Turing over JSON and stores is at a SQLite DB
• Membership DB - Secured storage of membership data.

TODO

• Add a secondary acnode and test multiple acnode functionality (Sol)
• Figure out a strategy of syncing the membership database to the local access database, as currently manual (mentar)
• Move the acserver to a separate VM running on the server downstairs (tgreer + mentar)
• Code a basic web ui for adding tools/maintainers/nodes (mentar)

AC Node

Currently proposed (and built) by Solexious Link

AC Server

2 versions Python Flask implementation started by ms7821 can be located here further improved by asoko

PHP Code Igniter implementation developed by mentar and Oskar located here

Usage: curl http://[server]:[port]/[node_id]/card/[card_id]

For testing it's installed on babbage port 1234

Membership DB

Running on Turing VM slice (hosted outside the space as it has personal data). Accessed in JSON format.
