Ustvari dva navidezna računalnika. Za prvega uporabi sliko diska simpleArbiterDhcp. Na drugem računalniku
ustvari uporabnika test z geslom test.
Na sliki diska simpleArbiterDhcp najdeš imenik s 100 datotekami. Prekopiraj vse datoteke na drugi računalnik v domači imenik uporabnika test.
Spremeni vsebino datotek tako, da vse male črke spremeniš v velike. Poskrbi, da se bo s prvega računalnika (simpleArbiterDhcp) mogoče prek
ssh prijaviti na drugi računalnik in prebrati predelane datoteke.

Create two virtual machines. For the first, use the `simpleArbiterDhcp' image.
On the second machine, create a user `test' with the password `test'.
The `simpleArbiterDhcp' disk image contains a folder with 100 files. Copy all
of these files to the other computer into the home folder of theuser `test'.
Modify the content of these files by converting all lowercase letters into
uppercase. Make sure that the first machine (`simpleArbiterDhcp') can use ssh
to access the second machine and read the processed files.
