Usage of nano text editor

+

+ 1.) Open the nano editor with the command nano which is followed by the path and name of the file. Example: nano /etc/myfile. If the file doesn't exist, the file will be created by the editor.
+ 2.) To move in the editor, we use the arrow keys, backspace is used for deleting.
+ 3.) To save a file press the combination of keys ctrl + O.
+ 4.) To exit the editor press the combination of keys ctrl + X. The editor will ask you, if you really want to exit, you can answer with y (yes ) or with n ( no ).
+ 5.) To cut a line press the combination of keys ctrl + K.
+ 6.) To paste a line press the combination of keys ctrl + U.
+ 7.) To search over a document press the combination of keys ctrl + W and then enter the search string. +

    1. Create two virtual machines Student(student-console) and Test(SimpleArbiterDhcpGw)

    2. Change the network settings to both virtual machines. SimpleArbiterDhcpGw: Adapter 1 set it to NAT, for internet access and Adapter 2 to internal network for local network. - Student: Adapter1 set it to "internal-network" so it is in the same domestic network as SimpleArbiterDhcpGw.

    5. In Student(student-console) open interfaces file ( nano /etc/network/interfaces ) and set the IP
      6. -
    6. We can check which interface belongs to which adapter in Virtual-box with MAC address. Run ifconfig command and compare the HWaddr value with the value in the Virtual-box ( settings => network => adapter => Mac address )
      7. -
    7. Then edit the /etc/motd, file with the specified string. (eg. "Not for Human consumption" )

    Uporaba nano urejavalnika besedila

    +

    + 1.) Urejvalnik nano odpremo z ukazom nano, kateremu sledi ime datoteke. Primer: nano /etc/mojadatoteka. Če datoteka ne obstaja jo bo ustvaril urejevalnik.
    + 2.) Po urejevalniku se premikamo s smernimi puščicami, brišemo z tipko backspace.
    + 3.) Za shranjevanje dokumenta pritisnemo kombinacijo tipk ctrl + O
    + 4.) Za izhod iz urejevalnika pritisnemo kombinacijo tipk ctrl + X. Pri tem nas urejevalnik upraša če želimo shraniti spremembe. Odgovorimo z y (yes, ja ) ali z n ( no, ne ).
    + 5.) Za izrez vrsticne uporabimo kombinacijo tipk ctrl + K.
    + 6.) Za lepljenje vrstice se uporablja kombinacija tipk ctrl + U.
    + 7.) Za iskanje po besedilu uporabimo kombinacijo tipk ctrl + W, nakar vnesemo iskani niz in pritisnemo tipko enter. +

  • Ustvari dva navidezna računalnika - imenujmo ju Test in Student. Za računalnik Test uporabite sliko diska, poimenovano Test. Na računalniku Test dobite kratek niz. Poskrbite, da se bo ta kratki niz pojavil v sporočilu, ki se ob prijavi izpiše na računalniku Student. Temu sporočilu v angleščini rečemo "message of the day" - MOTD.
    • +
  • Poskrbite, da se bo ob prijavi uporabnika (v Message Of The Day, MOTD) prek ssh izpisal nek niz. Računalnik nastavite tako, da bo dostopen s testnega računalnika (Test).
    • +
  • Uporabnišško ime in niz dobite kot parametre ob zagonu run_test.py. Pri nizu pazite, saj utegne biti dovolj dolg, da brez premikanja kurzorja ne bo takoj viden.
    • +
  • IP navideznega računalnika ter geslo nastavite sami.
    • +
  • Ocenjevalni program pričakuje, da se bo ob koncu prijave pojavila ukazna vrstica oblike uporabnisko_ime@ime_racunalnika:~$ . Pazite, da se bo takšna vrstica pojavila šele po nizu, ki ste ga dobili v navodilih.
