Lab Assessment 02
TASK-01: Linux Commands
Following are some tasks which should be executed in a terminal and
the corresponding screenshot should be included.
• Find out the ID of a specific process and cease its execution using
• Show how to move two files, F1.txt and F22.txt from Device
directory (/dev) to Home directory.
• Investigate the usage of ‘adduser’ command, and attach a
screenshot showing the successful completion of the command by
creating a new user named ‘HarryYourID’. Replace ‘YourID’ with
your CDU student ID. For instance – Harrys298900; don’t use
‘298900’, use your own ID. Online research is allowed for this
• Using Method-1* for chmod, set permission for a file in the format
rwx rw- -w- and rw- r-x –x.
• Using Method-2* for chmod, ‘Give Execute and Write’
permission to group and owner for a file.
* Refer to the chmod section of Linux command file for Method 1
TASK-02: Remote Desktop Connection
Setting up Remote Desktop Connection: 04
You are working as HelpDesk Support for an organization where your
usual duty involves providing remote users various IT related supports.
Majority of these users are placed in locations where high-speed LAN
(10Mbpds) are not available. Assume they are using the Darwin VM at
their end, and you have Canberra VM at your end. Now you will have to
set up Remote Desktop Connection from Canberra to Darwin; so that
you, with the physical access to Canberra VM, can remotely connect to
Darwin VM. You also have to ensure the connection is optimized for lowspeed broadband networks.
Follow the submission format and before starting this task ensure VMs
can ping each other.
TASK-03: Windows Firewall with Advanced Security
Creating Firewall Rules: 06
www.cdu.edu.au or cdu.edu.au has the IP address of 220.127.116.11.
Create an outbound firewall rule in any of the VMs that will allow the
VM’s browser to access all other websites except that of CDU’s one.
Name the rule according to your own CDU student ID, for instance
s298900. But don’t use ‘298900’, use your own ID.
Before you initiate the task, change the VM’s Network from ‘intnet’ to
‘NAT’, this will allow access to internet through your host (physical)
machine. So also ensure your physical machine is connected to internet.
You must provide all the necessary screenshots up until the creation of
the rule as well as results following the submission format. While
providing the result, include browser’s screenshot where it shows it can
access other websites but not CDU; plus in the same screenshot, include
ping screenshot where it shows – within one command box – a ping
request to 18.104.22.168 succeeds whereas another request to 22.214.171.124
fails (the format for screenshot is given next page).
126.96.36.199 is a public DNS server used and maintained by Google so it is
always up and running.
Now once you are done with the above and taken necessary screenshots
for the whole process and result; make required changes to the rule so
that this time, Ping requests to CDU goes through but the website still
remains unavailable. (hint: ping uses ICMP while Web Traffic uses TCP).
I’ve attached the following screenshot for reference, as you can see, the
browser and command box must be present within a single screenshot.
