RADIUSdesk is a complete, open source solution for the provision and management of Internet connectivity.
The main component is a feature-rich RADIUS server that includes features such as vouchers, BYOD and permanent users.
Permanent users have support for Private PSKs (Current under development) and versatile Fair Usage Policies (FUP).
There is also MESHdesk and APdesk, which allow you to manage OpenWrt-based hardware centrally via your phone or a desktop browser.
A rich API is included that allows for easy integration with other systems.
