The challenge site veteran matrixman
is challenging you to exploit his first warchall challenge which you can find in /home/level/matrixman/13_tryouts
on the box.
Of course you need to create your warchall account
if you haven't done so already.
Don't try random things on your target as it's pretty straight forward.

The warchall project is hosted on vr.org, a cloud based hosting service.
The service and support is unique, and they just have added additional 20GB HDD space for us for free! Thank you very much vr.org!
