justniffer is a TCP packet sniffer. It captures TCP packets, reassembles and reorders them, performs IP packet defragmentation and displays the TCP flow in the standard output. It is useful for logging HTTP network traffic in a "standard" (Web server like) or in a customized way. It can log the performance of network services (such as Web server response time or keep-alive behavior). It can be extended by scripts. One is provided for storing all captured HTTP content (such as images, JavaScript, CSS, or HTML) into files.
