====== Network Configuration ======


===== Overview =====


In this sequence of laboratory exercises you will set-up and configure a private Linux network with a gateway to the Internet.

This will give you experience of running a private IP network. 

The laboratory is intended to last for around two weeks. You will need to record your experience in your lab book or on-line in a web log. Your work will be assessed by [[eg-253:networkq:home|questionnaire]] that is to be completed by the end of term. 



===== Network Map =====

The architecture we will be attempting to recreate is based on a design for a private teaching network by Edouard Bougon who was an exchange student from France during the spring and early summer of 2005. 

===== About the Design ===== 
The design is quite flexible allowing you to: 
  * experience first-hand the creation and administration of an IP network 
  * examine live the various application, transport, network and link protocols that coexist on such a network 
  * create and administer several application services, most notably the web, but also DHCP, DNS, NAT, NFS and NIS. 
  * hone your Linux and sysadmin skills 

The network, once established, will become a teaching resource used in EG-253 in TB2 but also by level 1 ICCT students. 


===== Keep Good Notes =====

It is important that you keep good notes as you work through this configuration exercise. For your convenience, you can enter your notes directly into the [[eg-253:networkq:home|network configuration questionnaire]] which you have to submit for assessment.
