Configure the emulation VM

You will need an emulation Linux Virtual machine that runs mininet.

Install dnsmasq on your emulation vm.

   sudo apt-get install dnsmasq

Install python requests on your emulation vm

   sudo pip install python-requests

In order for DNS to work on mininet hosts you should not be using local caching. Edit /etc/NetworkManager/NetworkManager.conf and comment out.

    #dns=dnsmasq

For the dhcp test, edit /etc/dnsmasq.conf and set up DHCP addresses for testing:

    no-hosts
    addn-hosts=/etc/dnsmasq.hosts
    dhcp-range=10.0.0.1,10.0.0.10,72h
    dhcp-host=00:00:00:00:00:01,10.0.0.1
    dhcp-host=00:00:00:00:00:02,10.0.0.2
    dhcp-host=00:00:00:00:00:03,10.0.0.3

Add a fake hosts in /etc/dnsmasq.hosts of the emulation machine only by adding the following lines:

  203.0.113.13    www.nist.local
  203.0.113.14    www.antd.local
  203.0.113.15    printer.nist.local

Add the following to /etc/hosts on the emulation machine only in order to avoid timeouts:

 203.0.113.13	www.nist.local
 203.0.113.14	www.antd.local
 203.0.113.15       myprinter.nist.local

Make the following change in /etc/nswitch.conf

  #hosts:          files mdns4_minimal [NOTFOUND=return] dns
  hosts: files dns

Kill any existing instance of dnsmasq on the emulation VM. We will restart it in the test script.

  sudo pkill dnsmasq

If dnsmasq is running as a service, perform the following.

  sudo sed -i 's/^dns=dnsmasq/#&/' /etc/NetworkManager/NetworkManager.conf
  sudo service network-manager restart
  sudo service networking restart
  sudo killall dnsmasq

Configure the SDN Controller (OpenDaylight) Host

Add the following to /etc/hosts on your controller host so that the java library can look up our fake host.

  127.0.0.1      dhcptest.nist.local

(We will run the "manufacturer server" on 127.0.0.1 on the controller host.)

Run the following script on the controller host:

  sh copy-test-files-to-odl-cache.sh

This will copy the mudfiles to the cache in preparation for testing. To run mud-dhcp-test make sure you have the setup described in ../../README.md

Then clean the state of the controller:

 cd karaf/target/assembly/
 rm journal/*
 rm snapshots/*

Now start the controller:

cd bin
./karaf clean

At the karaf prompt, install the sdnmud feature

 karaf> feature:install features-sdnmud

Running the UNIT tests

Tests are run from the mininet emulation machine.

important BEFORE YOU BEGIN execute the following file from this directory on the controller :

  sh  copy-test-files-to-odl-cache.sh

This will copy the MUDfiles directly into the cache.

You can run the test as follows in each mud*test directory:

sudo -E UNITTEST=1 python mud-test.py

This will exercise the mud implementation and check if it is working as expected. If you would like to exercise the implementation from the command line, try the following

sudo -E UNITTEST=0 python mud-test.py

This will take you to the mininet command line from where you can run tests manually.

For the DHCP test check the instructions in the mud-dhcp-test directory.
