Product Overview

Packet Capture

Description: Packet capture software intercepts and logs network traffic passing through a network interface. It can help analyze network issues, view raw network packets, monitor bandwidth usage, debug protocols, etc. Popular open-source packet capture tools include Wireshark, tcpdump, and Windump.

tcpflow

Description: tcpflow is an open source tool for capturing TCP traffic flows. It works by capturing packets from network interfaces or packet capture files, reassembling TCP streams, and storing application-layer data with relevant TCP metadata.
