Welcome to the documentation for openNDS

openNDS (open Network Demarcation Service) is a high performance, small footprint, Captive Portal. It provides a border control gateway between a public local area network and the Internet.

It supports all ranges between small stand alone venues through to large mesh networks with multiple portal entry points.

Both the client driven Captive Portal Detection (CPD) method and gateway driven Captive Portal Identification method (CPI - RFC 8910 and RFC 8908) are supported.

In its default configuration, openNDS offers a dynamically generated and adaptive splash page sequence. Internet access is granted by a click to continue button, accepting Terms of Service. A simple option enables input forms for user login.

The package incorporates the FAS API allowing many flexible customisation options. The creation of sophisticated third party authentication applications is fully supported.

Internet hosted https portals can be implemented with no security errors, to inspire maximum user confidence.

It is a fork of the NoDogSplash project that in turn was derived originally from the codebase of the Wifi Guard Dog project.

openNDS is released under the GNU General Public License.

The following describes what openNDS does, how to get it and run it, and how to customize its behavior for your application.
