-<h2>Purpose of the exercise</h2>
-<p>How to create user? How to edit a file? How to connect to anoter computer using ssh? How to find out the computer IP address?</p>
-<h2>Brief description</h2>
-<p>Set up two virtual machines, set MOTD. Connect using ssh.</p>
-
-<h2>How To</h2>
-
-<ol>
- <li>Create two virtual machines, Student(student-console) and Test(SimpleArbiterDhcpGw) <br> <img src="../images/img4.png" alt="no img"></li>
- <li>Change the network settings to both virtual machines. SimpleArbiterDhcpGw: Adapter 1 set it to NAT for internet access, 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. <br> <img src="../images/img1.png" alt="no img"> <br> <img src="../images/img2.png" alt="no img"> <br> <img src="../images/img3.png" alt="no img"></li>
- <li>Login on <b>Student</b> <br> <img src="../images/img5.png" alt="no img"></li>
- <li>On Student(student-console) create a new user (with "adduser username", as the task demands of you ( eg. marjankoral19 ), with a custom password. <br> <img src="../images/img6.png" alt="no img"></li>
- <li>In Student(student-console) open interfaces file ( nano /etc/network/interfaces ) and set the IP <br>
- <h2>How to use the <strong>nano</strong> text editor </h2>
- <p>
- 1.) Open the nano editor with the command nano, which is followed by the path and name of the file. Example: <strong>nano /etc/myfile</strong>. If the file doesn't exist, the file will be created by the editor.<br />
- 2.) To move in the editor, we use the arrow keys, <strong>backspace</strong> is used for deleting. <br />
- 3.) To save a file press the combination of keys <strong>ctrl</strong> + <strong>O</strong>. <br />
- 4.) To exit the editor press the combination of keys <strong>ctrl</strong> + <strong>X</strong>. The editor will ask you, if you really want to exit, you can answer with <strong>y</strong> (yes ) or with <strong>n</strong> ( no ). <br />
- 5.) To cut a line press the combination of keys <strong>ctrl</strong> + <strong>K</strong>. <br />
- 6.) To paste a line press the combination of keys <strong>ctrl</strong> + <strong>U</strong>. <br />
- 7.) To search over a document press the combination of keys <strong>ctrl</strong> + <strong>W</strong> and then enter the search string.
- </p> <img src="../images/img7.png" alt="no img" ></li>
- <li>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 ) <br /><img src="../images/slika4.png" alt="no img" /><img src="../images/slika3.png" alt="no img"/></li>
- <li>Then edit the /etc/motd (eg. with nano editor like this: "nano /etc/motd"), file with the specified string. (eg. "Not for Human consumption" ) <br> <img src="../images/img8.png" alt="no img"> </li>
- <li>For testing, login with the test user into Test(SimpleArbiterDhcpGw) <br> <img src="../images/img9.png" alt="no img"></li>
- <li>Then connect to the Student with ssh, using the user marjankoral19 - ssh marjankoral@ip. <br> <img src="../images/img10.png" alt="no img"></li>
- <li>If the login was successful, the Message of the day should apear.</li>
- <li>To run Kpov_judge, login onto SimpleArbiterDhcpGw, find and run the file test_task.py ( with ./test_task.py as all other scripts )<br /> <img src="../images/img11.png" alt="no img"></li>
- <li>A window appears as we can see on the image above, then press Enter, enter your username ( eg. dr6784@student.uni-lj.si ), password, task name (eg. 01-preparation-set_motd), enter the string we should get in motd, enter the username and password of a user on Student(student-console)(eg. marjankoral19), the IP of Student(student-console), and after a brief moment we should get the result. <img src="../images/img12.png" alt="no img"> </li>

-<ol>
- <li>Ustvari dva navidezna računalnika, računalnik Student(student-console) ter računalnik Test(SimpleArbiterDhcpGw) <br> <img src="../images/img4.png" alt="ni slike"></li>
- <li>Spremeni omrežne nastavitve obema navideznima računalnikoma, SimpleArbiterDhcpGw: Adapter 1 na NAT za dostop do interneta, Adapter 2 na "internal network" za lokalno omrežje,
- Student: Adapter1 na internal-network, da je v enakem omrežju kot SimpleArbiterDhcpGw. <br> <img src="../images/img1.png" alt="ni slike" > <br> <img src="../images/img2.png" alt="ni slike"> <br> <img src="../images/img3.png" alt="ni slike"></li>
- <li>Prijavi se na računalniku Student. <br> <img src="../images/img5.png" alt="ni slike"></li>
- <li>Na računalniku Student(student-console) ustvari novega uporabnika (z ukazom "adduser imeuporabnika"), kot to od tebe zahteva naloga (npr. marjankoral19), geslo določi sam. <br> <img src="../images/img6.png" alt="ni slike"></li>
- <li>Računalnik Student, odpri datoteko interfaces ( nano /etc/network/interfaces ), ter nastavi IP. <br> <img src="../images/img7.png" alt="ni slike"></li>
- <h2>Kako se uporablja <strong>nano</strong> urejavalnika besedila: </h2>
- <p>
- 1.) Urejvalnik Nano odpremo z ukazom nano, kateremu sledi ime datoteke. Primer: <strong>nano /etc/mojadatoteka</strong>. Če datoteka ne obstaja jo bo ustvaril urejevalnik. <br />
- 2.) Po urejevalniku se premikamo s smernimi puščicami, brišemo s tipko <strong>backspace</strong>. <br />
- 3.) Za shranjevanje dokumenta pritisnemo kombinacijo tipk <strong>ctrl</strong> + <strong>O</strong> <br />
- 4.) Za izhod iz urejevalnika pritisnemo kombinacijo tipk <strong>ctrl</strong> + <strong>X</strong>. Pri tem nas urejevalnik upraša, če želimo shraniti spremembe. Odgovorimo z <strong>y</strong> (yes, ja ) ali z <strong>n</strong> ( no, ne ). <br />
- 5.) Za izrez vrstice uporabimo kombinacijo tipk <strong>ctrl</strong> + <strong>K</strong>. <br />
- 6.) Za lepljenje vrstice se uporablja kombinacija tipk <strong>ctrl</strong> + <strong>U</strong>. <br />
- 7.) Za iskanje po besedilu uporabimo kombinacijo tipk <strong>ctrl</strong> + <strong>W</strong>, nakar vnesemo iskani niz in pritisnemo tipko enter.
- </p><br />
- <li>Kateri vmesnik (npr. eth0) spada pod kateri adapter (npr. Adapter1 ), lahko preverimo s strojnimi naslovi. Na računalniku zaženemo ukaz ifconfig, pogledamo HWaddr vrednost ter jo primerjamo z vrednostjo v Virtual-boxu (nastavitve => omrežja => adapter => MAC address <br /><img src="../images/slika4.png" alt="ni slike"/><img src="../images/slika3.png" alt="ni slike"/></li>
- <li>Nato spremeni datoteko /etc/motd (z urejevalnikom nano, primer uporabe: "nano /etc/motd"), ter zamenjaj niz z ustreznim nizom kot to od tebe zahteva naloga ( npr. "Not for Human consumption" ) <br>
- <img src="../images/img8.png" alt="ni slike"> </li>
- <li>Za testiranje se s testnim uporabniškim imenom prijavi na prvem računalniku. (SimpleArbiterDhcpGw) <br> <img src="../images/img9.png" alt="ni slike"></li>
- <li>Nato se preko ssh poveži na računalnik Student z uporabniškim imenom marjankoral19 - ssh marjankoral19@ip. <br> <img src="../images/img10.png" alt="ni slike" ></li>
- <li>Po uspešni prijavi se bi moralo izpisati motd sporočilo.</li>
- <li>Kpov_judge poženemo tako da se prijavimo na računalniku SimpleArbiterDhcpGw, najdemo datoteko test_task.py ter jo poženemo ( z ./test_task.py kot se poganjajo vse skripte )<br /> <img src="../images/img11.png" alt="ni slike"></li>
- <li>Pojavi se nam okno kot ga vidimo zgoraj, nato pa pritisnemo tipko Enter, vnesemo svoje uporabniško ime ( npr. dr6784@student.uni-lj.si ), geslo, ime naloge (npr. 01-preparation-set_motd), vnesemo niz ki bi se nam moral prikazati, vnesemo ime uporabnika na računalniku Student (npr. marjankoral19) ter njegovo geslo, ip računalnika študent, nato pa po kratkem premoru dobimo rezultat. <img src="../images/img12.png" alt="ni slike"> </li>
