EpicTreasure - Batteries included CTF VM

Tools included

Docker

docker pull ctfhacker/epictreasure
docker run --rm -v /path/to/host/share/folder:/root/host-share --privileged -it --workdir=/root ctfhacker/epictreasure

Default settings

By default, my dotfiles are installed onto the VM. Simply comment out the following lines in Dockerfile if you don't want my settings.

# Personal dotfiles
RUN cd /root && \
    rm .bashrc && \
    git clone --recursive https://github.com/ctfhacker/dotfiles.git && \
    cd dotfiles && \
    ./install.sh

Then rebuild the Docker

docker build -t et .

Terminal

  • Colorscheme for the terminal and vim is solarized

Vim

  • jk or jj to ESC out of Vim
  • ESC and Arrow keys are hard coded to not work in Vim (as a teaching mechanism)
  • : is remapped to ; (who uses ; anyway?)
  • leader key is SPACE (thanks to spacemacs)
  • SPACE p will drop an embedded IPython line in a python script
  • H moves to beginning of line, L moves to end of line (instead of ^ and $)

Tmux

  • A new shell spawns a fresh tmux session
  • tmux leader switched to Ctrl+A
  • Ctrl+A - produces a horizontal pane. Ctrl+A \ produces a vertical pane.
  • Ctrl+A [hjkl] moves around available panes as vim motion
