When saving this file please use your first name and first letter of your last name, followed by “_Lab4” as the file name. For example, I would name the file AlanK_Lab4.docx. When you are done, save it and submit it to me via email () as an attachment.

Task 1:Cloning a Linux virtual machine

  1. Make sure the virtual machine you are working on can access the Internet. If not, be sure to configure your network settings as you did in Lab 1 through YaST.
  1. Power-off your Linux virtual machine, set its network adapter setting in NAT connection mode. Next click on VM menu ->Manage->Clone..->Next -> select The current state in the virtual machine->Next-> select Create a linked clone->Next-> Accept the default name and location or change them yourself ->Finish -> Close
  1. Power-on the cloned virtual machine. Open the Firefox web browser to see if it connects to the Internet. It should be running just fine except that it has the same hostname as the original VM. We’ll change their hostnames properly later in Task 3.

Task 2: Managing Linux Processes

Please work through thehandout Managing Linux Processes, and take screenshots as specified in each of the boxes below:

Screenshot after the command ssh nten@localhost is executed in step 17 of Exercise 2

Task 4: Tunnelling X through SSH

Screenshot of the ncurses-based version of YaST in Exercise 3 –part I.

Before doing Exercise #3, Part III, you may need to make sure you SLES DVD Disk 1 ISO is connected to your server vm.

Screenshot of the Remote Administration dialog in Exercise 3 – part III.
