Its flexible logging engine allows it to adapt to virtually any TCP‑based protocol, making it useful for debugging, performance analysis, and custom traffic inspection. Justniffer can decode HTTP requests and responses, extracting: - Client and server IP addresses - Requested URLs - HTTP headers - Message bodies - TLS info - Timing information (request time, response time, idle time, etc.) For non‑HTTP traffic, Justniffer provides a powerful and customizable logging system that allows you to extract any relevant information from the TCP data stream. Packet capture is performed using libpcap , ensuring compatibility with standard capture formats and tools such as tcpdump . --- Features - HTTP request/response decoding - Customizable log formats for any TCP‑based protocol - Performance metrics : request time, response time, idle time, connection time - libpcap‑based capture (live or from .pcap files) - Promiscuous mode support for passive monitoring - Extensible via external scripts (bash, Python, Perl, ELF binaries) — Learn more - Reconstructs TCP streams including reordering, retransmissions, fragmentation --- Quick Start Install on Ubuntu Capture HTTP traffic in access‑log style Add response time to each log entry Capture full HTTP requests and responses Use a custom log format Read from a PCAP f","default_branch":null,"files":null,"tree":[],"storefront":"/r/onotelli","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/onotelli/justniffer/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
