Naloga: Postavi tri navidezne racunalnike: 
- SimpleArbiter s sliko diska simpleArbiterDhcp,
- SNMPServer in 
-SNMPClient. 
Napiši program upminutes, ki bo izpisal v minutah koliko casa je racunalnik 
vklopljen.

Postavi ga na SNMPClient v domaci imenik uporabnika test z geslom test. 

Poskrbi, da bo SNMP strežnik prek SNMP pod 
NET-SNMP-EXTEND-MIB::nsExtendOutput2Table sporocal, koliko casa je vklopljen 
v sekundah.

Napiši skripto, poimenovano beri.sh, ki prek SNMP prebere vrednost s strežnika
 SNMPServer na OID 1.3.6.1.4.1.8072.1.3.2.4.1.4. 
Postavi jo na SNMP klienta, v domaci imenik uporabnika test z geslom test.

Napiši skripto gen_params(), ki uporabnikom generira razlicne parametre in
sicer razlicno število med 1 in 254 s pomocjo katerih bomo preverjali
ali je prislo do prepisovanja.

Navodila za ostale metode pa so obarvana rdece oz. komentirana z #

Set up three virtual computers, SimpleArbiter with the disk image simpleArbiterDhcp,
SNMPServer and SNMPClient. Write a program called upminutes. This program should output
the uptime of the computer in minutes. Set it up on SNMPClient in the home directory
of the user test with the password test.

Make sure that the SNMP server reports it's uptime in seconds over SNMP under 
NET-SNMP-EXTEND-MIB::nsExtendOutput2Table .

Write a script called beri.sh that reads the value from the OID 1.3.6.1.4.1.8072.1.3.2.4.1.4. 
on SNMPServer. Set it up on SNMPClient in the home directory of the user test.
