What is "justniffer"

Justniffer is a TCP packet sniffer. It can log network traffic in a 'standard' (web server-like) or in a customized way. It can also log response times, useful for tracking network services performances (e.g. web server, application server, etc.). The output format of the traffic can be easily customized. An example written in Python (delivered with the official package) stores the transferred contents in an output directory separated by domains. This means that the transferred files like html, css, javascript, images, sounds, etc. can be saved to a directory.
