+<h2>Namen vaje</h2>
+Naučite se, kako se nastavljajo omrežni vmesniki v večini sodobnih Linux distribucij (NetworkManager).
+</p>
+<p>
+<h2>Naloga na hitro</h2>
+Nastavi statičen IP v NetworkManager-ju, nastavi statični IP in DNS strežnik v /etc/network/interfaces. Oba naslova računalnikov in DNS strežnikov dobite ob zagonu run_test.py.
+</p>
+<p>
+<h2>Navodila</p>
+<ol>
+<li>Iz imenika s slikami virtualnih računalnikov povlecite slike maliNetworkManager, maliBrezNetworkManager, SimpleArbiterDhcp</li>
+
+<li>Nastavite omrežja navideznih računalnikov tako, da bo<br/>1. omrežni vmesnik SimpleArbiterDhcp povezan na isto omrežje kot edini omrežni vmesnik maliNetworkManager in maliBrezNetworkManager,<br/>
+  2. vmesnik SimpleArbiterDhcp bo povezan na NAT ali fizično omrežje, kjer prek DHCP dobi naslov in pot (prehod, gateway) do Interneta.</li>

+Z ukazom <pre>ping 193.2.1.66</pre> preverite, ali je SimpleArbiterDhcp na Internetu. Če je, boste približno vsako sekundo dobili odziv. Ping prekinete
+s kombinacijo tipk CTRL+C.<br/>
+ Če SimpleArbiterDhcp ne pride do Interneta, v VirtualBox zamenjajte nastavitve 1. in 2. omrežni vmesnik ter ponovno zaženite navidezni računalnik.

+<li>Poženite run_test.py.</li>
+
+<li>Kot ime naloge vpišite 03.predvaja</li>

+V zavihku "IPv4" spremenite "Method" na "Manual". Kliknite na "Add". Nastavite statični IP, ki ste ga prebrali na SimpleArbiterDhcp kot statični IP A.<br/>
+V DNS servers dodajte naslov Arnesovega DNS: 193.2.1.66

+
+<li> Odprite datoteko /etc/network/interfaces. Popravite nastavitve v skladu s podatki, ki ste jih dobili na SimpleArbiter. Vnos za omrežni vmesnik mora izgledati približno takole:<br/>
+<pre>
+allow-hotplug eth0
+iface eth0 inet static
+    10.0.1.2
+    netmask 255.255.255.128
+    dns-nameservers 10.0.1.5
+</pre>
+</li>
+
+<li> Shranite nastavitve. Z ukazom reboot ponovno zaženite maliBrezNetworkManager. NetworkManager ob zagonu računalnika
+prebere, kateri omrežni vmesniki so nastavljeni v /etc/network/interfaces. Za te vmesnike potem ne skrbi več.</li>
+
+</li>Na SimpleArbiterDhcp pritisnite OK. Če je šlo vse po sreči, ste opravili tokratno nalogo.</li>
