Docker Environment

Interactive Shell

You can start an interactive shell in each of the Docker containers by using the following commands:

docker exec -it source bash
docker exec -it channel bash
docker exec -it sink bash

Wireshark

If you want to have a look at the network traffic inside the Docker containers, you can start Wireshark from your host system inside the network namespace of one of the containers. For example, you can start Wireshark inside the network namespace of the channel container, where FlowEmu is running, by using the following command:

sudo ip netns exec channel wireshark

You should then be able to select between the interfaces in and out, which are connected to the source and sink containers, respectively.
