Ustvari dva navidezna računalnika - imenujmo ju SimpleArbiterDhcpGW in
Student. Za računalnik SimpleArbiterDhcpGW uporabite sliko diska, poimenovano
SimpleArbiterDhcpGW.
Na računalniku Student ustvarite uporabnika z uporabniškim imenom {peer_user}.
Poskrbite, da se bo v sporočilu, ki se ob prijavi izpiše na računalniku
Student, pojavil niz "{niz}". Temu sporočilu v angleščini rečemo
"message of the day" - MOTD.
IP navideznega računalnika Student ter geslo za {peer_user} nastavite sami.
Ocenjevalni program pričakuje, da se bo ob koncu prijave pojavila ukazna
vrstica oblike uporabnisko_ime@ime_racunalnika:~$ .
Pazite, da se bo takšna vrstica pojavila šele po nizu, ki ste ga dobili v
teh navodilih.

Create two virtual machines - named SimpleArbiterDhcpGW and Student.
For the 'SimpleArbiterDhcpGW', use disc image named SimpleArbiterDhcpGW.
On Student, create a user with the username {peer_user}.
Set the message of the day (MOTD) on Student to "{niz}". This is the message
which is displayed when you log in.
Set the IP of Student and the password for {peer_user} yourself.
The grading system expects that at the end of login,
a prompt similar to username@name_of_computer:~$ appears.
Make sure that this line shows up only after the
string you got in these instructions.
