The only thing that's left in our procedure is how exactly we can create these fake DNS requests on various machines. We need to send DNS queries to our machine with a hostname that matches one of the %mapping hash keys in order to trigger the commands. Assuming our key is openssh, we can use any of the following commands, depending on what software you have installed and what operating system you're running.

    You'll need to supply the IP address or hostname of your Linux machine to the lookup command to make sure that the packet goes here directly, since the command hostnames (e.g. 'openssh') you use will not actually resolve.
