Could someone PM me with some help in getting a shell? I’ve been trying for hours, and for some reason the reverse shells never work - I get no answer to my listeners. And yes, I’ve resetted the box half a dozen times.
stuck here as well 
would appreaciate any help to get a shell (have tried staged, unstaged, meterpeter and nishang as well but no luck)
