Pcapviewer

Overview

PcapViewer is a powerful, multi-platform tool that simplifies network traffic analysis, bringing essential PCAP/PCAPNG file inspection capabilities directly into your preferred environment: Visual Studio Code, Terminal UI, a standalone Desktop Application, or a dedicated Web Service.

It enables users to dive into network traffic and inspect various protocol layers, from the Ethernet layer to the application layer, providing a streamlined alternative to full-scale tools like Wireshark. With its lightweight nature, it’s ideal for developers, network administrators, and engineers who need quick insights into network packets.

🌟 Features

• Native Integration: Seamless operation as a custom editor within VS Code.
• Multi-format Support: Handles .pcap, .pcapng, and .cap files.
• High Performance: Utilizes WASM and Rust for fast and efficient packet analysis.
• Extensible Design: Open to contributions and improvements via the modular architecture.

🔌 Protocol Support

- File Formats: PCAP, PCAPNG - Link Layer: Ethernet II, PPPoE, IEEE 1905.1a, IEEE 802.11, SSL - Network Layer: IPv4, IPv6, ARP, RARP, ICMP, IGMP - Transport Layer: TCP, UDP - Application Layer: TLS, HTTP, DNS, DHCP, SSDP, SIP
