Setup of a DNS Server with Dynamic Updates

Abstract

Today the need for dynamic reconfiguration of IP addresses increases. This is mostlydue to the increased mobility among Internet connected devices. The purpose of theproject was to develop a solution for dynamic DNS with updates initiated by the client. There are already various commercial solutions available today, but they have somelimitations. The goal was to implement a system based on already available componentswith only minor adaptations. This report describes an implementation based on aRADIUS server (FreeRADIUS), which is accessed through a web interface(daloRADIUS). The authentication process is secured by a server certificate. Due totime constraints the implemented result should be considered as an early prototype. The conclusion of the project is that the concept works and that it is possible with some effort to solve the problem in a relatively simple way.
