What Others Think

It's just the basic usage of tcpdump, isn't it? Except you've used -s0 to set the snapshot length to its DEFAULT. . You haven't explained the options you've used. The sample output just contains the command. It was the same with your zip commands -- basic usage. . To get an upvote, I'm looking for a command that will give me the wow factor. Make me think, "That's useful", or "That's a clever solution to the problem". . The commands don't even have to be useful to me (or anyone) IMHO. (my last command certainly wasn't). But hopefully it'll make people laugh, or think :-)
