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