Purpose of the assignment

+Learn how to setup network interfaces in most modern Linux distributions (NetworkManager). +

+

+

Quick instructions

+Set a static IP in NetworkManager, set a static IP and DNS server in /etc/network/interfaces. You'll get both IP's when you execute script run_test.py. +

+

+

Instructions

+
    +
  1. From the directory with images of virtual computers, download the following:
    maliNetworkManager, maliBrezNetworkManager, SimpleArbiterDhcp.
    2. + +
  2. Set the network for virtual computers, so that SimpleArbiterDhcp's 1. nework interface is connected to the same network, as the only network interface for maliNetworkManager and maliBrezNetworkManager,
    + SimpleArbiterDhcp's 2. network interface will be connected to a NAT or a physical network, where the address and route (gateway) to the internet is obtained via DHCP.
    3. + +
  3. Start SimpleArbiterDhcp. Sign in as user "tester" with password "SedemKrogovPekla".
    4. +
  4. +slika-04
    +Use command 
    ping 193.2.1.66
    to check if SimpleArbiterDhcp is connected to internet. If you get ping reply, you're connected to the internet. Cancel the ping with combination CTRL+C.
    + If SimpleArbiterDhcp doesn't have internet access, change the network settings in Virtual box for 1. and 2. network interface, then restart the virtual computer. + +
    5. +
  5. Run the script run_test.py.
    6. + +
  6. Enter "03.predvaja" as assignment name.
    7. + +
  7. Read the maliNetworkManager's static IP . Leave SimpleArbiterDhcp running in the background until you have setup the maliNetworkManager.
    8. + +
  8. Start maliNetworkManager.
    9. + +
  9. +Sign in the GUI(graphical user interface) using username "student" and password "vaje".
    10. +
  10. ikona network manager
    +Right click on the icon for network settings.
    + +
  11. +Menu NetworkManager
    +Choose "Edit Connections"
    12. + +
  12. +Menu NetworkManager
    +Click "Edit"
    13. + +
  13. +Menu NetworkManager
    +In tab "IPv4" change the "Method" to "Manual". Click "Add". Set the SimpleArbiterDhcp's static IP as static IP A.
    +Add Arnes DNS: 193.2.1.66 to DNS servers. +
    14. +
  14. Click "Save"
    15. + +
  15. Switch to SimpleArbiterDhcp. Click "Enter" or "OK".
    16. + +
  16. Read maliBrezNetworkManager's IP . Click "OK". Read the DNS server's address .
    17. + +
  17. Switch to maliBrezNetworkManager. Switch to first console using combination CTRL+ALT+F1. Sign in as root (su) with password "kaboom".
    18. + +
  18. Open the file /etc/network/interfaces. Edit the settings according to the information you got on SimpleArbiter. Entry for network interface should look something like this:
    +
    +allow-hotplug eth0
+iface eth0 inet static
+    10.0.1.2
+    netmask 255.255.255.128
+    dns-nameservers 10.0.1.5
+
    +
    19. + +
  19. Save the settings. Use the command 
    reboot
    to restart maliBrezNetworkManager. On boot the NetworkManager reads which network interfaces are configured in /etc/network/interfaces. After that NetworkManager doesn't manage these interfaces anymore.
    20. + + +Press OK on SimpleArbiterDhcp. If all went ok, you have completed this assignment. +

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. Z imenika s slikami virtualnih računalnikov povlecite slike maliNetworkManager, maliBrezNetworkManager, SimpleArbiterGW
    2. + +
  2. Nastavite omrežja navideznih računalnikov tako, da bo
    1. omrežni vmesnik SimpleArbiterGW povezan na isto omrežje kot edini omrežni vmesnik maliNetworkManager in maliBrezNetworkManager,
    + 2. vmesnik SimpleArbiterGW bo povezan na NAT ali fizično omrežje, kjer prek DHCP dobi naslov in pot (prehod, gateway) do Interneta.
    3. + +
  3. Zaženite SimpleArbiterGW. Prijavite se kot uporabnik tester z geslom SedemKrogovPekla
    4. +
  4. +slika-04
    +Z ukazom 
    ping 8.8.8.8
    preverite, ali je SimpleArbiterGW na Internetu. Če je, boste približno vsako sekundo dobili odziv. Ping prekinete +s kombinacijo tipk CTRL+C.
    + Če SimpleArbiterGW 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 preparation
    7. + +
  7. Preberite statični IP maliNetworkManager. Pustite SimpleArbiterGW 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. +

    +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 SimpleArbiterGW kot statični I.
    +V DNS servers dodajte naslov DNSja, ki van ha poda run_test.py. Kot gateway dodaj IP SimpleArbiterGW. +
    14. +
  14. Kliknite "Save".
    15. + +
  15. Preklopite na SimpleArbiterGW. 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
+    address "Podan IP"
+    netmask 255.255.255.0
+    dns-nameservers "Podan DNS"
+    getway "IP SimpleArbiterGW"
+
    +
    19. + +
  19. Shranite nastavitve. Z ukazoma "ifdown eth0", in ifup eth0" posodobite NetworkManager ki prebere +kateri omrežni vmesniki so nastavljeni v /etc/network/interfaces. Za te vmesnike potem ne skrbi več.
    20. + +Na SimpleArbiterGW pritisnite OK. Če je šlo vse po sreči, ste opravili tokratno nalogo. +
