My ctf environment

This sets up a ctf environment i've been using ad-hoc for a little while. Its not perfect but enough to get you up and running.

Some things I do are:

• Always use private internet access for a vpn. (Other vpn services are available)
• Use Dropbox to share ctf files between VMs. This is my persistant storage with all my previous ctf problems and solutions.
• Do most of my work in the ubuntu VM. Kali for pen testing tools, and windows for when its required

notes / issues

Make sure you have ruby 2.6 or later installed. Tested with 2.6.6

You also need bsdtar. For this i installed Vagrant via the installer then copied the included bsdtar to C:\Windows\System32. The default location is C:\HashiCorp\Vagrant\embedded\mingw64\bin\bsdtar.exe

• Kali box file does not exist for hyper-v and i haven't created one yet. so vagrant up or vagrant up ctf-kali will not work on windows.

ctf-ubuntu

1. Default user is vagrant
