 ==INVESTIGATION 1: USING AUTOMOUNT WITH '''NFS'''==

#You will have to adjust your firewall settings on your VM2 machine to allow NFS to work (Tip: run the '''netstat''' command in order to determine the <u>'''ports '''</u> needed and issue the appropriate ''iptables'' command or commands). Make certain to save your current iptables rules so they remain unchanged whey you reboot your NFS server and your client VM.

#Ensure make certain that your '''VM3''' machine can connect to the VM guest network and that your '''VM1''' machine is functioning properly. You running as the DNS server (Tip: you can use the "host cbc.ca" command to see if DNS queries are being answered. #Ensure Make certain that you have full connectivity to the internetare logged into your '''VM3''' machine.#Again, you should not have to install any NFS softwareInstall the '''nfs-utils''' package on your '''VM3''' machine.
