Thanks for this box. I have learned something totally new which took me 2 days to get this working as expected 
for foothold simply run the basic enumerations and check what you have on your box to help you to get in.
for user simply review what you got from foothold and how to use also existing tools on your box to get in.
for root: don’t make it too complex but understand what the tool is doing and how to manage this.
