Termshark — Termshark is a terminal based network protocol analyzer. It allows you to inspect network traffic and analyze packets, similar to Wireshark, but runs in a terminal instead of a graphical interface.

tcpflow offers Captures TCP traffic flows from live network interfaces or packet capture files, Reassembles TCP streams and stores application-layer data, Stores TCP metadata like sequence numbers, acknowledgments, window advertisements, Supports BPF filters for selective capturing, Outputs flows in various formats like ASCII, CSV, JSON, while Termshark provides Captures live packet data from network interfaces, Displays packets in a terminal user interface, Filters packets using display filters, Analyzes protocols including TCP, UDP, HTTP, DNS, and more, Supports common capture file formats like PCAP and PCAPNG.

tcpflow stands out for Open source and free, Lightweight and fast, Powerful BPF filtering capabilities; Termshark is known for Lightweight terminal-based interface, No GUI overhead or dependencies, Works over SSH connections.

Product Overview

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.

Termshark

Description: Termshark is a terminal based network protocol analyzer. It allows you to inspect network traffic and analyze packets, similar to Wireshark, but runs in a terminal instead of a graphical interface.
