    +1 Thanks
    
    This took a bit more work to validate since the sensors don't just work 
auto-magically.  I had to manually restart each of the sensors and pcap-replay 
for things to really start functioning.
    
    After running the following commands, I am able to see the number of alerts 
growing for each of the 3 demo sensors.
    
    ```
    vagrant --ansible-skip-tags="sensor-stubs" up
    vagrant ssh
    sudo su - 
    service pcap-replay restart
    service yaf restart
    service snortd restart
    service snort-producer restart
    ```
