Development of WiFi Hotspot billing Application

Deployment of a CentOS based Linux server to act as prepaid Internet management platform. Around 20 simultaious users will be using the system at any given time, however this number might increase so the system should have no limitation in that sense. Ive designed the logic and explain in more depth the scope of this server in the attached documents. While the actual logic of the process can be changed, the network infrastructure should remain the same. Third party AP integrated platforms or similar are not an option. I belive the following is an overview of the requred tasks to achive the scope of the server; Development of Captive Portal mechanism Development of scripts to analyze and record traffic information Development of scripts to apply dynamic rules to iptables accordingly Development of web gui for user management and web portal The selected bidder should have a good understanding of iptables or linux firewalls , linux networking, networking in general and development of clean and user friendly web applications.
