I managed to find a small hole in a web application that appeared as if it wold allow me to execute commands on the local machine.  I tried a simple reverse shell but no joy.  Taking it down to a very basic level, I tried to ping but I needed to capture my ping requests on the other end.  


    I've spent a number of years bouncing back and forth between *nix machines and Windows machines.  But after the 90's, Windows really took hold and I've spent more hours on Windows than anything else and yet when I get a shell on a Windows machine, I feel like I have less control.  Scratch that, I HAVE less control but I can get what I want from outside of the box through PowerShell.


    I remember when I would get this error -- seemed like the kiss of death as far as trying to maneuver once I got a shell.  I'd flounder around, trying to figure out how to accomplish the task at hand but this issue would severely limit my ability.

    Somewhere along the way, I discovered the cause -- you don't have a TTY.   What do you do?
