tcpdump vs Termshark

tcpdump — tcpdump is a command-line network monitoring and data acquisition tool used to capture packet data flowing over a network. It can intercept and log traffic passing over a digital network or part of a

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.

tcpdump offers Packet capture and network traffic monitoring, Capture filters for selective packet capture, Reading packets from files for offline analysis, Output to console, files, or other programs, Decoding of various network protocols, 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.

tcpdump stands out for Free and open source, Available for multiple platforms, Powerful command line interface; Termshark is known for Lightweight terminal-based interface, No GUI overhead or dependencies, Works over SSH connections.
