Ustvari dva navidezna računalnika - SimpleArbiter z diska simpleArbiterDhcp ter
RadiusServer.SimpleArbeiterDhcp dobis na naslovu polz.si/media/uploads/kpov/virtualke.Na RadiusServer namesti OpenRadius. Dodatna navodila za instalacijo najdete na evbergen.home.xs4all.nl/openradius/doc-using-openradius.html.OpenRadius uporablja dve konfiguracijski datoteki. To sta /etc/openradius/configuration in /etc/openradius/behaviour.
Prejsnja definira serverjeve vire in vmesnike slednja pa nastavi, kako bo server delal z zahtevami.  Na SimpleArbiter preberi uporabnisko ime in geslo
uporabnika ter ga dodaj v konfiguracijo OpenRadius na RadiusServer. Na SimpleArbiter
preberi skrivnost ter poskrbi, da se bo s to skrivnostjo SimpleArbiter lahko povezal
na RadiusServer .

Nato na OpenRadius namesti še podatkovno bazo mysql. Na SimpleArbiter preberi še ime podatkovne baze, 
uporabniško ime na bazi ter geslo, s katerim se bo lahko klient s SimpleArbiter na to bazo lahko povezal.
Ustvari podatkovno bazo.Najprej namestimo mysql server. Nato se prijavimo v Mysql server z ukazom mysql -u root -p. Bazo ustvarimo z ukazom CREATE DATABASE <imePodatkovneBaze>. V bazi ustvari tabelo "users" s stolpcema username ter password. 
Na RadiusServer ustvari uporabnika test. Nastavi PAM tako, da se bo geslo uporabnika primerjalo z vnosom
v tabeli v mysql, namesto da se uporabi datoteka /etc/passwd oziroma /etc/shadow.
