Step 1: Build a Docker image that has Dshell installed and configured
sudo docker build -t dshell .
Step 2: Run the container with a native host directory (/home/user/pcap/) mounted in /mnt/pcap
sudo docker run -v /home/user/pcap:/mnt/pcap -it dshell
Step 3: Use Dshell to analyze network traffic
decode -d netflow /mnt/pcap/*.pcap
