			** NOTE: In this lab you are setting up a DHCP server on your Linux system, this can cause problems for other computers on the same network if you give them incorrect DHCP addressing! In the book they have you disconnect from the network and use a crossover cable to your partner. Instead you can create a connection between two of your VMs and disconnect them from the regular network. BEFORE starting your VM to do this lab open the Virtualbox Network Settings for each of the VMs you are going to use. Switch them from "Bridged Adapter" to "Internal Network" this will connect each of the VMs to a private network on your system where you can experiment with a DHCP server. When you are DONE with this lab you need to make sure the DHCP service (daemon) will not start automatically on boot (remember we talked about how to set default startup for services in chapter 8) and then shutdown the VMs and switch them back to "Bridged Adapter" mode to get them back on the network.

			==EXTRA CREDIT LAB==
			# Log in to your Ubuntu Server VM
			## Check the current IP address, subnet mask, default gateway and nameserver used by your system (note this will require the use of several different programs)
			## Determine the IP address of '''google.com''' using all three of the DNS/hostname resolution tools (do not use ping or traceroute which are not DNS resolution tools) and see how the output differs. If you are on campus you may need to log in to safeconnect using the links or lynx web browser before you will be able to reach off campus locations.
			## Check what order of files and services are used to resolve names on your system
			## Try changing your system hostname both immediately and permanently
			## Change the IP configuration of your system to have a private static IP address of 192.168.2.XX where XX is the number of your computer (check the label on the front). Don't forget to apply the changes. Use a subnet mask of 255.255.255.0 there is no default gateway needed. If you're doing this lab off campus you can select any number for XX as long as it's not already used on your network.
			## Verify the IP address changes took effect, this time using the newer '''ip''' utility instead of the old '''ifconfig''' method. More information on the newer utility can be found [http://lartc.org/howto/lartc.iproute2.explore.html here].
			# Log in to your Fedora VM (do not turn off the Ubuntu Server VM)
			## Change the IP configuration of your system (using the command line) to have a private static IP address of 192.168.2.1XX where XX is the number of your computer (note the 1 in front of the computer number this time so as to avoid an IP address conflict). Use a subnet mask of 255.255.255.0 there is no default gateway needed. If you're doing this lab off campus you can select any number for XX as long as it's not already used on your network.
			## Verify the IP address changes took effect.
			## Put entries in the hosts file of both your Ubuntu and Fedora systems so that you can access the other one by name instead of address
			## Test connectivity between the systems using the ping command and by establishing an SSH session between the two VMs.
			## Restore your Fedora system to DHCP addressing
			# Shutdown your Fedora system and return to your Ubuntu Server VM
			## Restore your Ubuntu system to DHCP addressing
			## Test system connectivity to the Internet by pinging and tracing the route to google.com

			** NOTE: Completing this project will completely erase your Fedora installation and re-install it. You will loose any data or customizations you have done to your virtual machine. If you would like to avoid this you can use the instructions from project 5-2 (above) to copy your edited ks.cfg file to a virtual floppy disk, load it into a new virtual machine, and install Fedora using the kickstart option ks=hd:fd0:/ks.cfg to load the ks.cfg file from your virtual floppy drive.
			** NOTE: In step 2 of this lab you edit your ks.cfg file to include settings about drive and partition sizes. Your virtual hard drive sizes may vary from the 30GB root partition and 4GB swap partition used in the book. Edit the sizes in your ks.cfg file to be appropriate for your virtual hard disk.

			*# Even though our logical volumes are now 4GB and 6GB respectively that space is still not available for storage because the volumes were smaller when we formatted them. Luckily, ext4 supports resizing the filesystem even after data is on the volume and while the partition is in use (online).
