Usposobite tri računalnike: +

+

+

Prvi omrežni vmesnik računalnika SimpleArbiter naj bo povezan na Internet. Drugi naj bo povezan na neko lokalno omrežje, na katerega bosta priklopljena računalnika Z_DHCP ter BREZ_DHCP. Na računalniku Z_DHCP poskrbite, da bo ob pridobivanju naslova DHCP strežniku poslal tudi posebej nastavljeno ime računalnika (hostname), ki ne bo enako dejanskemu imenu računalnika (tistemu, ki ga izpiše ukaz hostname).

+

Naslov BREZ_DHCP ter ime računalnika za Z_DHCP dobite ob zagonu run_test.py na računalniku SimpleArbiter. Uporabniško ime ter geslo na SimpleArbiter sta

Namen vaje

+Naučite se, kako se nastavljajo omrežni vmesniki v večini sodobnih Linux distribucij (NetworkManager). +

+

+

Naloga na hitro

+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. +

+

+

Navodila

+
    +
  1. Iz imenika s slikami virtualnih računalnikov povlecite slike maliNetworkManager, maliBrezNetworkManager, SimpleArbiterDhcp
    2. + +
  2. Nastavite omrežja navideznih računalnikov tako, da bo
    1. omrežni vmesnik SimpleArbiterDhcp povezan na isto omrežje kot edini omrežni vmesnik maliNetworkManager in maliBrezNetworkManager,
    + 2. vmesnik SimpleArbiterDhcp bo povezan na NAT ali fizično omrežje, kjer prek DHCP dobi naslov in pot (prehod, gateway) do Interneta.
    3. + +
  3. Zaženite SimpleArbiterDhcp. Prijavite se kot uporabnik tester z geslom SedemKrogovPekla
    4. +
  4. +slika-04
    +Z ukazom 
    ping 193.2.1.66
    preverite, ali je SimpleArbiterDhcp na Internetu. Če je, boste približno vsako sekundo dobili odziv. Ping prekinete +s kombinacijo tipk CTRL+C.
    + Če SimpleArbiterDhcp ne pride do Interneta, v VirtualBox zamenjajte nastavitve 1. in 2. omrežni vmesnik ter ponovno zaženite navidezni računalnik. +
    5. +
  5. Poženite run_test.py.
    6. + +
  6. Kot ime naloge vpišite 03.predvaja
    7. + +
  7. Preberite statični IP maliNetworkManager. Pustite SimpleArbiterDhcp da teče v ozadju, dokler niste nastavili maliNetworkManager
    8. + +
  8. Zaženite maliNetworkManager.
    9. + +
  9. +Prijavite se v grafično okolje z uporabniškim imenom student, geslom vaje
    10. +
  10. ikona network manager
    +Desno-kliknite na ikono za mrežne nastavitve
    + +
  11. +Menu NetworkManager
    +Izberite "Edit Connections"
    12. + +
  12. +Menu NetworkManager
    +Kliknite "Edit"
    13. + +
  13. +Menu NetworkManager
    +V zavihku "IPv4" spremenite "Method" na "Manual". Kliknite na "Add". Nastavite statični IP, ki ste ga prebrali na SimpleArbiterDhcp kot statični IP A.
    +V DNS servers dodajte naslov Arnesovega DNS: 193.2.1.66 +
    14. +
  14. Kliknite "Save"
    15. + +
  15. Preklopite na SimpleArbiterDhcp. Pritisnite "Enter" oz. "OK".
    16. + +
  16. Preberite IP maliBrezNetworkManager. Pritisnite "OK". Preberite naslov DNS strežnika.
    17. + +
  17. Preklopite na maliBrezNetworkManager. Preklopite na prvo konzolo s kombinacijo CTRL+ALT+F1. Prijavite se kot root z geslom kaboom.
    18. + +
  18. 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:
    +
    +allow-hotplug eth0
+iface eth0 inet static
+    10.0.1.2
+    netmask 255.255.255.128
+    dns-nameservers 10.0.1.5
+
    +
    19. + +
  19. 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.
    20. + +Na SimpleArbiterDhcp pritisnite OK. Če je šlo vse po sreči, ste opravili tokratno nalogo. +
