Let's learn tcpdump!

Ever wanted to know how to use tcpdump, but were intimidated by all the command line options? I was too! But then I learned it, and it wasn’t as bad as I thought. In this zine we’ll explain:

  • what kinds of questions you can answer with tcpdump
  • how to interpret tcpdump output
  • which command line arguments are the really important ones
  • how to write a BPF filter to filter tcpdump output

There’s a Russian translation.
