Na rdateClient ustvarite uporabnika test z geslom test. Nastavite čas na rdateClient tako, da kot rdate strežnik uporabite SimpleArbiterDhcpRdate. Nato v domačem imeniku uporabnika test spravite program z imenom guliver, ki prebere 4 byte podatkov s standardnega vhoda in jih pretvori v predznačeno celo število, pri čemer naj uporablja zapis z debelim koncem (big endian). Število naj program izpiše na standardni izhod.
