Background

ThreeRound is a new startup specializing in custom built software. You’re our new CIO and IT-department. Welcome!

This is our company: Maija Välikari, John Doe, Äijä Yrmy, Teija Vanhakuja-Oikarinen, Teppo Kärniö.

Users

Create users for everyone.

Write all users names and passwords to a text file ‘services.txt’ in your home directory. The file is /home/yourname/services.txt, where yourname is your login name. Include your own (sudo user’s) password and user name.

Protect the file so that other users can’t read it.

Web

Create a sample homepages for everyone. Leave all homepages open on tabs after the exam.

Maija and Äijä want to do PHP coding, so create “hello PHP world” for each of them.

Coders

ThreeRound wants to create new commands of its own. Write a sample shell script ‘threeround’, and make it available for all users. Any user should be able to run the command while in any directory, without specifying path.

Run the command, and leave a terminal open showing it run.

Remote access

All users want to access the computer remotely from various countries. Make it possible for users to access the system remotely.

Leave a sample connection visible on the screen.

Ghosts in the LAN

They say that the previous operator of the network, fobarion, is now haunting the network. It is said passed away when he got a heart attack while trying to sort trough Snort packet logs. Now he connects to services he sees in the network.

Find proof that ‘fobarion’ tried to access your computer. He will always use the name ‘fobarion’ when he connects. Put this proof into ‘services.txt’ you created earlier.
