Namesti VirtualBox. Ustvari dva navidezna računalnika. Pri enem od njiju (imenujmo ga TEST)
kot disk uporabi datoteko Test_disk1. Na drugega (imenujmo ga A) namesti poljubno Linux distribucijo.
Poskrbi, da bosta oba računalnika na istem omrežju. Na računalnik A namesti strežnik ssh.
Z računalnika TEST se prek ssh poveži na A. Poskrbi, da bo TEST imel dostop tako do Interneta, kot
tudi do računalnika A.
