Purpose of the exercise

+

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?

+

Brief description

+

Set up two virtual machines, set MOTD. Connect using ssh.

+ +

How To

+ +
    +
  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, 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.

  4. On Student(student-console) create a new user (with "adduser username", as the task demands of you ( eg. marjankoral19 ), with a custom password.

  5. In Student(student-console) open interfaces file ( nano /etc/network/interfaces ) and set the IP

    How to use the 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. +

  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. Then edit the /etc/motd (eg. with nano editor like this: "nano /etc/motd"), file with the specified string. (eg. "Not for Human consumption" )

  8. For testing, login with the test user into Test(SimpleArbiterDhcpGw)

  11. To run Kpov_judge, login onto SimpleArbiterDhcpGw, find and run the file test_task.py ( with ./test_task.py as all other scripts )

  12. 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. no img
