[advice]how about add an volume?

[Tiaonmmn]

When using tcpdump to capture traffic,it will save contents when container stops.But if you start the container,it would clean original capture.pcap.So how about add an volume on Dockerfile?
Just a little advice,don't mind it.

Your advice is useful, I will add a more solid traffic capture method later, maybe change tcpdump to tshark.
For now, you can manually add -v your_dump_volume:/var/lib/tcpdump to your docker create or docker run command to prevent data loss.

Use asuri/ctf-xinetd:1.0.1
