• Ansible
• Creating VMs using Ansible
• Using Ansible commands to create workshop environment
• Access to NSRC materials
• Campus network security and NAT

• Trac

Objectives by Topics

Days 1-2

1. Write and use a lesson plan
   • write specific objectives
   • design a variety of classroom activities
   • use a variety of methods to evaluate student progress
   • deliver a lesson in accordance with the plan

2. Plan a course of instruction or complete a pre-planned course following the points in 1.

Day 3

3. Build a workshop virtualization host using ansible
   • install and partition server
   • describe the relationship between physical volumes, volume groups and logical volumes
   • extend a VG by adding a second PV
   • install ansible
   • locate and unpack the ansible configs
   • configure ansible hosts file and run ansible

4. Have an understanding of the components of a virtualized training platform, including:
   • list the layers of the solution (OS, libvirt, LXC, bridging utilities, network emulation)
   • explain the purpose of libvirt
   • compare the operation of physical machine emulation and containers (e.g. KVM vs LXC) and list some advantages of each
   • explain why software bridges are required
   • say which commands are used to list libvirt instances (virsh list, virsh list --all)
   • say which command is used to show bridge port membership (brctl show)
   • say which commands are used to start and manage the dynamips emulator (dynamips, dynagen)
   • bring up and test the eth1 / br-wan interface
   • connect to the server using ssh from their laptop
   • connect the access point and network switch
   • associate clients and have them reach the Internet via the host
   • use tcpdump to show client traffic
   • read the DHCP log files
   • locate and edit the configuration files for network interfaces, iptables, DNS, dhcp - for example, be able to configure a static forwarder for the DNS server

4a. In addition students will be able to:

• list the requirements of local network infrastructure (gateway/NAT, local DNS, local DHCP, wireless access, local webserver for teaching materials)
• list the requirements of workshop teaching platform (running Linux instances for students, running router/switch instances for students, interconnections, providing student access to those instances)

Day 4

5. Create an initial virtual machine using KVM
   • Create an initial virtual machine image using python-vmbuilder
   • Create an instance in libvirt from an XML template
   • Start and Stop an initial virtual machine using virsh (libvirt)

6. Manage a virtual machine
   • rebuild the VM image (optional)
   • Start and stop a VM
   • login to a VM using serial console
   • login to a VM using ssh
   • login to a VM using public / private keys

7. Clone the initial virtual machine using provided scripts
   • Clone the initial virtual machine using cp/rsync and same XML template
   • Add the virtual machine to libvirt
   • Clone the initial virtual machine using a script which sets the MAC address and adds it to libvirt

8. Manage virtual machines
   • Start and stop multiple VMs using command line looping
   • make bulk changes to a VM using ssh and command line loops

Day 5

9. Understand and configure linux network interfaces to prepare for both the CND topology and NMM topology
   • label (or draw from scratch) the new CND topology and/or the current NMM topology
   • describe the lines in /etc/network/interfaces used to create bridge interfaces, create tap interfaces, assign IP addresses, and bring them up automatically on start
   • use brctl and ifconfig to show the status of interfaces
   • use ifup and ifdown to up/down a specific interface
   • edit /etc/network/interfaces to add a new bridge interface
   • edit the ansible configuration and use it to write a new /etc/network/interfaces (possible)
   • explain why a full reboot may be required after changing /etc/network/interfaces

10. Understand and use the initial NMM and CND topologies, including running through an initial exercise in both environments.

• Start a screen session, detach from the session and reconnect
• start dynamips and bind it to a TCP port
• use dynagen to start a routers.net file (implies they have a ready-to-run routers.net)
• explain what happens when dynagen is killed
• leave dynagen running somewhere where it can be reconnected (*)
• start, stop and reload individual routers
• import configurations for individual routers and all routers (implies we have ready-to-load configs in a directory or zip bundle)

Extra

11. Obtain materials from the NSRC Git repository:
    • Via the web interface and download a zip bundle of repositories
    • paste their ssh public key in to their profile
    • use git clients (we may be out of time for this) with ssh/http to pull repositories (r/o access)

12. Learn about proper CND and planning for requested DEAs
    • Draw a diagram with proper network planning - routing at the core, switching at the edges
    • Describe the planning process before attempting DEA at an institution
