network data, packet captures


Justniffer is a network protocol analyzer that captures network traffic and produces logs in a customized way.

Justniffer can emulate Apache web server log files, track response times and extract all "intercepted" files from the HTTP traffic. It lets you interactively trace tcp traffic from a live network or from a previously saved capture file. Justniffer's native capture file format is libpcap format, which is also the format used by tcpdump and various other tools. Justniffer captures reassembles and reorders TCP packets, performs IP packet defragmentation and displays the tcp flow in the standard output. It is useful for logging network traffic in a 'standard' (web server like) or in a customized way. It can log network services performances (e.g. web server response time , application server keep alive behaviour, etc.). Output format can be customized using the log format option.
