Where can I get a good traffic analyzer?

Question

Analytics

How to implement the ability to analyze the traffic passing through the network in order to see what files (documents, images, etc.) are passing through the network? preferably with file names and extension (document type). Are there any utilities or companies that do this?

Answer 1

There are a lot of analyzers, ranging from the workhorse tcpdump to tshark, trafshow, wireshark, etc.
But apparently you don't need an analyzer or even a sniffer. You need a grabber. Information stealing software.
I must say right away that this software is old. Since few people are engaged in such nonsense. For example here: www.liveinternet.ru/tags/lan+grabber
Here is another

Answer 2

wireshark not working?

Answer 3

If this is a corporate network, then we google InfoWatch Traffic Monitor at the request, if it's just a local network - the comments are higher.
