Those are a few simple things you can do with tcpdump, but it doesn't really illuminate the network traffic much. Why are the students looking at the tcpdump output? There is no explanation of the network traffic - like what a packet is made of (the headers, the payload), the different protocols, the types of packets that implement the different protocols - etc. Then again, maybe you aren't going into that much depth. But to me, that is the point of tcpdump - to look at the traffic and to understand it. Sometimes with the ultimate goal of finding out what's going wrong with the network. What do you want the students to get out of it? What do the students already know about Linux/Unix? From the plan you gave, they know "cat" (and now they know tcpdump) and have to be taught how to stop a running process (ctl-c) and how to redirect output to a file. I think it is good to use a program like tcpdump to introduce some basics - but maybe a bit more emphasis on teaching shell things like redirection and linux/unix concepts like processes will be a good foundation for them to learn other things. And, you have put the synopsis on the page - but here is a chance to introduce the man pages instead. Well those are my impressions - I hope this is useful for you. I think it's great that you want to teach the kids some command-line tools : -) bjb On Thu, Mar 26, 2020 at 01:25:58PM -0400, Plotnick, Neil via tcpdump-workers wrote:Date: Thu, 26 Mar 2020 13:26:55 -0400 From: "Plotnick, Neil" <nplotnick () everett k12 ma us> Subject: Intro Lesson Plan/Tutorial To: tcpdump-workers () lists tcpdump org I have posted a tutorial designed for my introductory cybersecurity class at my high school.
