1. Modern Operating Systems 2014 Practice Tasks

2. Lab1. OS Installation. Boot configuration Install Dual boot system Linux / Windows 7 or 8 / win server 2012(Dreamspark for example) Virtualbox with 2 hd -s and install linux on one hd and windows on second one use windows boot manager to boot both systems in one hdd and Linux boot manager to boot both system in second hdd

3. Lab2. User settings Configure the Linux machine the following way (use the skeleton file for this): Change the background image Change the greeting text in the console Each new user in the system must have the directory named Downloads Create couple of new users and verify the settings

4. Lab3 Users and Groups Create group Leidurid Create users klaus, bruno, paula ja eduard Set klaus group to leidurid Set bruno group to users and leidurid Set paula group to users Set eduard group to leidurid

5. Lab4. Access rights Your task is to create access rights (in form of rwx), which corresponds to the 4-digit number DCBA. The number ABCD you get if you sum up your student code and 2222, take 4 least significant digits, substitue 8 with 4 and 9 with 3. Describe the process step by step.

6. Lab5. File system Create catalog /var/www/leiutised which belongs to group leidurid. Others should be granted with only read access to the directory. Check if user paula can access the directory. Try to create several files with all the users outlined in the previous lab and inspect their corresponding access rights.

7. Lab6. File system Add to the VM a spare 8GB virtual HDD. Create 4GB partition in it and format into xfs. Edit the /etc/fstab file appropriately so that the new file system gets mounted at system boot.

8. Lab7 (basic) Scripting Home assignment : Write script in powershell and in bash to do : 1. Archive only new or modified files from directory to archive directory 2. Archive it to archive directory by compressing each file separately (with zip, or tar or etc) and naming the archive OriginalFileNameDDMMYY.extension where OriginalFileName is the original file name DD is Two-digit day, e.g. 02 MM Two-digit month, e.g. 04 YY Two-digit year, e.g. 96 extension is the extension for the arcive, eg tar.gz,.zip etc..

9. Lab8 (advanced) Scripting In addition monitor directory for changes as soon new file appear in directory doo mentioned tasks.

10. Lab9. Software installation Check if the VM needs to update any of the software packages installed in it. List all the packages that require update (and the process how did you get that), perform an update and verify that the machine no further needs any updates.

11. Lab10. Virtualization Install LXC package on the Linux VM Create two VM-s following the predefined template Configure the networking (useful commands are brconfig, ifconfig) Configure both VMs to start with the host system boot and limit each VM to 200 MB RAM usage.

12. Lab11. Windows Check the process table of the windows system. Which process takes most resources? Which process is the slowest? Can you find any suspicious files or processes there? Install antivirus software and scan the system for suspicious activities. What are the results?
