Instant Messaging Simulation

Prerequisites

This repository depends on tshark which can be found in most package managers such as apt.

apt install tshark

You need to change the permisisons for your user such that it is part of the wireshark group as outlined in the wireshark readme. You may need to restart your machine for the change in group permissions to take effect.

sudo usermod -a -G wireshark $USER

It is probably not ideal to be part of this group long-term so you might want to remove yourself from the group when you are done with this repository.

Container runtime

Use crun to run containers deamon-less for less memory footprint.

wget https://github.com/containers/crun/releases/download/1.20/crun-1.20-linux-amd64
sudo mv crun-1.20-linux-amd64 /usr/bin/crun
sudo chmod +x /usr/bin/crun

Add or replace daemon.json to enable use of crun runtime.

mv daemon.json /etc/docker/
