I recreated the BoF OSCP environment after running out of lab time. It helped immensely on the exam after practicing a few times and I made a writeup of it below.
Hopefully, this helps some of you preparing for the OSCP exam! Feedback and questions always welcomed, this writeup took an extremely long time
