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.

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

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.
