=NAD710 - Introduction to Networks - Using Linux=

=Objectives=
* Setup a LAN with three subnets
* Use the route and sysctl command to configure a Linux router
* Use the network analyzing tools to study the changes in IP header when a packet crossing a router

=Hardware Requiremetns=
* Five Linux Machines (FC8/FC9)
* Two network switches (D-Link)
* Seven Cat 5 straight through cables

=Procedure=
* Setup THREE networks: 
** Network A: 10.0.0.0/8,
** Network B: 172.16.0.0/16, and 
** Network C: 192.168.1.0
* Setup THREE Hosts, one in each network
** Host A: 10.0.0.1
** Host B: 172.16.0.1
** Host C: 192.168.1.1
* Setup TWO Linux routers: Router R-ab and R-bc
** Router R-ab: eth0 10.0.0.254, eth1 172.16.0.254
** Router R-bc: eth0 172.16.254.254, eth1 192.168.1.254 
* Use the ping command to verify that ALL 5 Linux systems (three hosts and two routers) can communicate with each other.
* Run the appropriate commands on ALL five Linux systems to capture IP packets that are coming in and going out on each network interface and save to separate files
* Use the wireshark package to study the IP header and investigate what fields were changed when a packet move from the source to the destination with routers in between the path.
=Completing the Lab=
Write up a report on your findings with a properly labeled network diagram and the commands used to setup the LAN.
Email your report in PDF format to your instructor by the due date
