Ustvari tri navidezne računalnike. Za disk prvega uporabi sliko diska simpleArbiterDhcp.
Za enega od ostalih dveh (Z_DHCP) poskrbi, da bo dobil IP prek DHCP, pri čemer
naj kot hostname strežniku pošlje ime, ki ga dobiš na simpleArbiterDhcp.
Za drugega (BREZ_DHCP) poskrbi, da bo imel statično nastavljen IP.
Prvi omrežni vmesnik računalnika SimpleArbiter naj bo povezan na Internet. Drugi naj bo povezan na neko lokalno omrežje, na katerega bosta priklopljena računalnika Z_DHCP ter BREZ_DHCP. Na računalniku Z_DHCP poskrbite, da bo ob pridobivanju naslova DHCP strežniku poslal tudi posebej nastavljeno ime računalnika (hostname), ki ne bo enako dejanskemu imenu računalnika (tistemu, ki ga izpiše ukaz hostname).
Naslov BREZ_DHCP ter ime računalnika za Z_DHCP dobite ob zagonu run_test.py na računalniku SimpleArbiter.
