<p>
Ustvari dva navidezna računalnika - imenujmo ju <em>arbiter</em> in <em>student</em>.
Na računalniku <em>student</em> ustvarite uporabnika z uporabniškim imenom <code>{{peer_user}}</code>. IP navideznega računalnika <em>student</em> ter geslo za uporabnika <code>{{peer_user}}</code> nastavite sami.
<p>
Poskrbite, da se bo v sporočilu, ki se ob prijavi izpiše na računalniku <em>student</em>, pojavil niz
<pre><code>{{niz}}</code></pre>
<p>
Temu sporočilu v angleščini rečemo <em lang="en">message of the day</em> oziroma <em>MOTD</em>. Ocenjevalni program pričakuje, da se bo ob koncu prijave pojavila ukazna vrstica oblike
<pre><code>username@hostname:~$ </code></pre>
Pazite, da se bo takšna vrstica pojavila šele po nizu, ki ste ga dobili v teh navodilih.

<p>
Create two virtual machines named <em>arbiter</em> and <em>student</em>. On <em>student</em>, create a user with the username <code>{{peer_user}}</code>. Set the IP of <em>student</em> and the password for <code>{{peer_user}}</code> yourself.
<p>
Set the <em>message of the day</em> (MOTD) on <em>student</em> to
<pre><code>{{niz}}</code></pre>

This is the message which is displayed when you log in. The grading system expects that after login a prompt similar to

appears. Make sure that this line shows up only after the string you got in these instructions.
