OPS235 Lab 6 - Fedora17

Configuring a Network Using Virtual Machines

Caution!
This lab is very much under construction. Please do not start it until this warning is removed.

Objectives

• Use the Fedora GUI program to configure network interfaces with static IP configuration and host name resolution
• Use the find command to locate the configuration files modified by the GUI network configuration program
• To examine some of the Linux's TCP/IP configuration files in the /etc/ directory
• To configure a Fedora host with static network configuration without a GUI tool
• To use and interpret the netstat command to troubleshoot and monitor network services
• To configure the linux firewall iptables to allow/disallow/forward different types of network traffic using simple rules

Reference

• man pages for find, ifconfig, ping, netstat, NetworkManager, nslookup, iptables, arp
• Online reading material for week 8.

Required materials

• Fedora 12 Live CD or a classmate on the same pod
• USB flash drive, 64 MB or more in size (Warning: the contents of this drive will be erased)
• One SATA hard disk in a removable drive tray with Fedora host and 3 Fedora Virtual Machines installed

Current Configuration

Currently you should have the following network configuration:

• Fedora host has 1 active network interface (probably eth0)that receives IP configuration from the School's DHCP server.
• Fedora host has 1 active network interface (virbr0) that has a static default configuration of 192.168.122.1/255.255.255.0
• Fedora1 VM has 1 active interface (eth0) that receives a dynamic configuration from your Fedora Host
• Fedora2 VM has 1 active interface (eth0) that receives a dynamic configuration from your Fedora Host
• Fedora3 VM has 1 active interface (eth0) that receives a dynamic configuration from your Fedora Host

Lab Preparation

Important We will be working with your 3 VM's
Start all 3 VM's for this lab.

Important
It is advisable to perform a yum update on your Fedora host and all 3 VM's.
