First , ensure that the '''host ''' and '''domain name ''' is set correctly on each of your four machines (host and three VMsvia /etc/hosts):

* '''host.yoursenecaid.org'''* '''vm1.yoursenecaid.org'''* '''vm2.yoursenecaid.org'''* '''vm3.yoursenecaid.org'''

Note You should notice that these host and domain names are settings that are <u>local </u> to each mahcinemachine, e.g. you will still not be able to contact '''vm1.yoursenecaid.org ''' from '''vm3'''. That's because occurs since you are currently you're using the '''Seneca ''' and other public DNS servers which know nothing about domain name: ''yoursenecaid.org''

This preparation step is in fact actually unnecessary to complete our goal for the this lab 's purpose (do you know why?) but . On the other hand, by performing the above operations, it will make things look appear more consistent, which will and may make your life a little easier.
