Welcome the Linux Network Administration.

Week 1 (January 12) - Overview of TCP/IP and Configure Networking Environment

  • Setting up a small (4 nodes) physical Local Area Network
  • Setting up a Virtual Local Area Network using FC10
  • Review of end-node and gateway network configuration
  • Manual and automatic network configuration

Lab 1 

Study the virtualization platform on Fedora Core 10
                 or
Set up a Four-node LAN in Lab T2107

If you want to use VMWare, Check here for pre-build virtual machine images for VMWare

Week 2 (January 19) - Protecting your Local Network with a Packet Filtering Firewall

Lab 2 Modify the sample firewall script and run it on your LAN gateway and hosts to allow access to the following services on your LAN

  • ssh, and
  • all the ports specified in the file /etc/openports
    • the first field of each line is the port number, the second field is the transport, and the rest is description or comment
    • line starts with the # sign is a comment
  • all the ports to be forwarded specified in the file /etc/fwports
    • this file should exist only on a gateway/router machine
    • line starts with the # sign is a comment
    • the first field of each line is the port to be forwarded, the second filed is the transport, and the rest is description or comment

After testing your firewall, use the iptables-save command to save the output to a file. Name the file on the gateway as "gw-fw.txt" and name the file on the host as "host-fw.txt".

Email both files to your instructor by Feb 3, 2009.
