VisualEther transforms Wireshark's packet captures (PCAP/PCAPNG) into easily interpretable sequence diagrams, allowing AI coding agents such as Claude Code to articulate, in straightforward language, the reasons behind a network session's failure. While Wireshark provides a detailed view of each packet, it does not present the overall conversation; VisualEther generates this conversation directly from the capture file—ensuring accuracy and reproducibility—with over 82 integrated protocol templates that cover a wide range, including 5G NR, 5G core, LTE, IMS/VoLTE, SIP/RTP, BGP, OSPF, DNS, HTTP/2, HTTP/3, TLS, Kerberos, Diameter, GTP, and various industrial protocols like Modbus, DNP3, and EtherNet/IP. An included MCP server selectively extracts only the relevant messages and fields, enabling an AI agent to process kilobytes of structured information rather than an overwhelming amount of raw packet data, effectively conducting an author-debug-verify cycle that references specific frame numbers as proof. Built upon the functionality of tshark, if Wireshark can analyze it, VisualEther can create a diagram for it. With capabilities for observation, analysis, diagnosis, and automation, VisualEther is available on Windows (through winget), macOS (via Homebrew), and Linux (using apt/dnf), offering a free Community edition alongside paid Professional and Server editions for more advanced needs. This comprehensive tool not only streamlines network analysis but also enhances the troubleshooting process for IT professionals.
