A Go library for packet decoding, capture, and network traffic analysis.
GoPacket is a Go library that provides packet decoding, capture, and analysis capabilities for network traffic. It allows developers to parse raw network packets, decode various protocols, and build tools for network monitoring, security, or debugging. The library interfaces with libpcap/WinPcap for live packet capture and supports extensible protocol layers.
Go developers building network monitoring tools, security applications, protocol analyzers, or any software requiring low-level packet inspection and manipulation.
Developers choose GoPacket for its comprehensive protocol support, high performance, and seamless integration with Go's ecosystem, offering a native Go alternative to C-based packet processing libraries with easier deployment and maintenance.
Provides packet processing capabilities for Go
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Decodes a vast array of protocols from Ethernet to TCP/UDP, as listed in key features, making it essential for diverse network analysis tasks.
Optimized for speed with minimal allocations, per the features, enabling efficient processing for high-throughput applications like network monitoring.
Supports custom decoders for unsupported protocols, allowing flexibility beyond built-in layers, as emphasized in the extensibility feature.
Interfaces with libpcap/WinPcap for real-time packet capture, providing direct access to live network traffic without external tools.
Relies on libpcap/WinPcap, complicating installation and cross-platform builds, especially in environments without C toolchains or with strict policies.
The README is minimal and points to godoc, which lacks tutorial-style guides, forcing developers to rely on examples or trial-and-error for setup.
Minimum Go version requirements vary (e.g., 1.9 for some components), adding complexity to dependency management and potential compatibility issues.
