CTF문제 풀때 vm 키는거보다 Docker가 성능상이나 속도상, 그리고 엄청 편할거 같아서, 다음같은 Dockerfile를 구성해서 image를 만들어놨다.

FROM c2w2m2/pwn:16.04
MAINTAINER c2w2m2 <juchang0308@gmail.com>
COPY . /home/ctf

이런식으로 끌어다가 쓰면 된다. 적당히 커스텀마이징도 문제따라 하면 될거고 맘에 든다.

이거보다 더 편한 방법으

#!/bin/sh
sudo docker run --cap-add=SYS_PTRACE -v `pwd`:/home/ctf/binary -it c2w2m2/pwn:${1} /bin/bash

이거 쉘스크립트 따놓고 setup {16.04, 18.04, 19.04} 하면 덴다
