This repository contains a set of docker images for CORE and a script to (re)build them all.

Clone the repo.

Run ./generate_images.

All containers are derived from an Ubuntu 20.04 (minimal) container

This is a basic container with iproute2 and ethtool for CORE compatibility and dropbear as a lightweight SSH server.

This image builds upon coreemu-base by adding terminal tools:

• dumb-init procps for process management;
• nano vim-tiny for file editing;
• tmux to handle multiple terminal windows with a single terminal connected to the container.

This image builds upon coreemu-termtools by adding networking tools:

• knot-host for DNS;
• iperf3 mtr-tiny net-tools iproute2 ifupdown inetutils-ping tcpdump for network testing/administration;
• openssh-client ncat socat telnet wget curl ca-certificates to act as client/server for different protocols.

This image builds upon coreemu-termnettools by adding more advanced sniffing tools:

• termshark (and tshark implicitly) for command-line/terminal usage of wireshark;
• tcpflow as a simple tcp flow reconstruction utility.

This image builds upon coreemu-sniffer by adding a CTF tool:

• pwntools;
• and associated dependencies/recommendations (among which ipython3 python3-pip git and build-essential).

This image builds upon coreemu-pwntools by adding the packet crafting tool scapy.
