+Postavite tri računalnike - SimpleArbiterSNMP s sliko diska simpleArbiterSNMP, ServerSNMP s sliko
+diska serverSNMP ter SNMPClient.
+
+Na SNMPClient ustvarite uporabnika test z geslom test. V datoteko /home/test/alarmi zapišite
+vse IP in vse OID, s katerih po SNMP prihajajo alarmi. Za vsak alarm zapišite eno vrstico,
+v kateri bosta najprej IP, nato OID, ločena s presledkom.
+
+V datoteko /home/test/vmesniki vpišite imena vseh omrežnih vmesnikov, ki jih prek SNMP dobite na
+ServerSNMP.
