=LAB PREPARATION=
[[Image:my-network.png|thumb|right|350px|Setting up networks is an essential operation for a system administrator. Maintaining network connectivity and securing the network are also essential operations. In this lab, we will '''configure a Virtual Private Network private virtual network using static IP addresses''' (eg. wired workstation connections). We will learn how to setup a DHCP network (eg. for notebook, table and smartphones) in lab 8.]]
===Purpose / Objectives of Lab 6===
|}
=INVESTIGATION 1: CONFIGURING A VIRTUAL NETWORK (VPN)=
For the remainder of this course, we will focus on networking involving our VMs. This lab will focus on setting up a virtual network, connecting our VMs and c7host machine to the network, and configuring our private network to make more convenient to use, troubleshoot and protect. '''Lab 7''' will focus on configuring SSH and making access to the private network more secure. Finally, '''lab 8''' will focus on configuring mobile (as well as wired devices) via DHCP to automatically assign an IP address.
<li value="1">Let's start with our '''centos1 VM'''. Double-click on your '''centos1''' VM, but instead of running the VM, click on the '''view''' menu, and select: '''Details'''<br />(Note: the Virtual Machine window will appear - do not start virtual machine)</li>
<li>In the '''left pane''' of the Virtual Machine window, select '''NIC:''' and note that this NIC is on the "default" virtual network</li>
<li>Change it to '''Virtual Network network1: NAT''' (i.e. the VPN network that you just created) and click the '''Apply''' button.</li>
</ol>
</li>
# When finished, check your settings, and then click the '''Apply''' button.
# Open a terminal and issue the '''ifconfig''' command to confirm the IP ADDRESS settings change.
# Verify that '''centos1'''VM is now connected to the VPN private network by issuing the following command from your '''c7host''' machine:<br><b><code><span style="color:#3366CC;font-size:1.2em;">ping 192.168.235.11</span></code></b>
[[Image:network-scripts.png|thumb|right|250px|Although you can use the '''ifconfig''' command to temporarily create a static IP address connection to a network, you need to add the network settings in the '''/etc/sysconfig/network-scripts''' directory to automatically connect to the network upon Linux system boot-up.]]
=== Part 3: Configuring VM Network Setup via Command Line ('''centos3''' and '''centos2''') ===

<ol><li value="7">Give this shell script execute permissions and run this shell script.</li><li>You will need to determine the full pathname of the '''ifcfg-ens33''' file in the /etc/sysconfig/network-scripts directory to use '''as an argument ''' for this shell script.</li><li>Run the shell script. What do you notice from the report that the shell script generated?</li><li>Then use wget command to download another variation of the network-info.bash shell script using the awk command to separate the variables and values into separate columns:<br><b><code><span style="color:#3366CC;font-size:1.2em;">https://ict.senecacollege.ca/~ops235/labs/network-info-2.bash</span></code></b><br></li></ol>
